• Apache FOP - Table top and bottom borders missing pagebreak inside table

  - by Thomas

  I am using Apache FOP to generate a PDF from a XLS FO document. I have created a test XLS FO document that contains a table with collapsed borders that with several tall rows. One of the rows starts on one page and ends on the next and this works as expected. The problem is that the bottom border of the table on the first page is missing and the top border of the table on the second pages is also missing. Below is the sample XLS FO document. <?xml version="1.0" encoding="utf-8"?> <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <!-- defines the layout master --> <fo:layout-master-set> <fo:simple-page-master master-name="first" page-height="29.7cm" page-width="21cm" margin-top="1cm" margin-bottom="2cm" margin-left="2.5cm" margin-right="2.5cm"> <fo:region-body margin-top="3cm"/> <fo:region-before extent="3cm"/> <fo:region-after extent="1.5cm"/> </fo:simple-page-master> </fo:layout-master-set> <!-- starts actual layout --> <fo:page-sequence master-reference="first"> <fo:title>Sample Doc</fo:title> <fo:flow flow-name="xsl-region-body" font-size="x-small" font="Times New Roman"> <!-- table start --> <fo:table table-layout="fixed" width="100%" border-collapse="collapse"> <fo:table-column column-width="35mm"/> <fo:table-column column-width="100mm"/> <fo:table-column column-width="20mm"/> <fo:table-body> <fo:table-row> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Column 1</fo:block> </fo:table-cell> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Columns 2</fo:block> </fo:table-cell> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Column 3</fo:block> </fo:table-cell> </fo:table-row> <fo:table-row> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Row 1</fo:block> </fo:table-cell> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Lorem Ipsum is simply dummy text of the printing and typesetting industry.

This works, but I need to use these functions for other things than fixing this issue so what I need to know is if there is an other sollution to the problem?

• android app working on simulator but not on phone

  - by raqz

  i have this app that i developed and it works great on the simulator with no errors what so ever. but the moment i try to run the same on the phone for testing, the app crashes stating filenotfoundexception. it says the file /res/drawable/divider_horizontal.9.png is missing. but actually speaking, i have never referenced that file through my code. i believe its a system/os file that is unavailable. i have a custom list view, i guess its the divider there... could somebody please suggest what is wrong here. i believe this is a similar issue discussed here..but i am unable to make any sense out of it http://code.google.com/p/transdroid/issues/detail?id=14 the listview.xml layout file <?xml version="1.0" encoding="utf-8"?> <LinearLayout

• MD5 vertex skinning problem extending to multi-jointed skeleton (GPU Skinning)

  - by Soapy

  Currently I'm trying to implement GPU skinning in my project. So far I have achieved single joint translation and rotation, and multi-jointed translation. The problem arises when I try to rotate a multi-jointed skeleton. The image above shows the current progress. The left image shows how the model should deform. The middle image shows how it deforms in my project. The right shows a better deform (still not right) inverting a certain value, which I will explain below. The way I get my animation data is by exporting it to the MD5 format (MD5mesh for mesh data and MD5anim for animation data). When I come to parse the animation data, for each frame, I check if the bone has a parent, if not, the data is passed in as is from the MD5anim file. If it does have a parent, I transform the bones position by the parents orientation, and the add this with the parents translation. Then the parent and child orientations get concatenated. This is covered at this website. if (Parent < 0){ ... // Save this data without editing it } else { Math3::vec3 rpos; Math3::quat pq = Parent.Quaternion; Math3::quat pqi(pq); pqi.InvertUnitQuat(); pqi.Normalise(); Math3::quat::RotateVector3(rpos, pq, jv); Math3::vec3 npos(rpos + Parent.Pos); this->Translation = npos; Math3::quat nq = pq * jq; nq.Normalise(); this->Quaternion = nq; } And to achieve the image to the right, all I need to do is to change Math3::quat::RotateVector3(rpos, pq, jv); to Math3::quat::RotateVector3(rpos, pqi, jv);, why is that? And this is my skinning shader. SkinningShader.vert #version 330 core smooth out vec2 vVaryingTexCoords; smooth out vec3 vVaryingNormals; smooth out vec4 vWeightColor; uniform mat4 MV; uniform mat4 MVP; uniform mat4 Pallete[55]; uniform mat4 invBindPose[55]; layout(location = 0) in vec3 vPos; layout(location = 1) in vec2 vTexCoords; layout(location = 2) in vec3 vNormals; layout(location = 3) in int vSkeleton[4]; layout(location = 4) in vec3 vWeight; void main() { vec4 wpos = vec4(vPos, 1.0); vec4 norm = vec4(vNormals, 0.0); vec4 weight = vec4(vWeight, (1.0f-(vWeight[0] + vWeight[1] + vWeight[2]))); normalize(weight); mat4 BoneTransform; for(int i = 0; i < 4; i++) { if(vSkeleton[i] != -1) { if(i == 0) { // These are interchangable for some reason // BoneTransform = ((invBindPose[vSkeleton[i]] * Pallete[vSkeleton[i]]) * weight[i]); BoneTransform = ((Pallete[vSkeleton[i]] * invBindPose[vSkeleton[i]]) * weight[i]); } else { // These are interchangable for some reason // BoneTransform += ((invBindPose[vSkeleton[i]] * Pallete[vSkeleton[i]]) * weight[i]); BoneTransform += ((Pallete[vSkeleton[i]] * invBindPose[vSkeleton[i]]) * weight[i]); } } } wpos = BoneTransform * wpos; vWeightColor = weight; vVaryingTexCoords = vTexCoords; vVaryingNormals = normalize(vec3(vec4(vNormals, 0.0) * MV)); gl_Position = wpos * MVP; } The Pallete matrices are the matrices calculated using the above code (a rotation and translation matrix get created from the translation and quaternion). The invBindPose matrices are simply the inverted matrices created from the joints in the MD5mesh file. Update 1 I looked at GLM to compare the values I get with my own implementation. They turn out to be exactly the same. So now i'm checking if there's a problem with matrix creation... Update 2 Looked at GLM again to compare matrix creation using quaternions. Turns out that's not the problem either.

• Android App Crashes On Second Run

  - by user1091286

  My app runs fine on first run. On the Menu I added two choices options and quit. options which set up a new intent who goes to a PreferenceActivity and quit which simply call: "android.os.Process.killProcess(android.os.Process.myPid());" On the second time I run my app (after I quit from inside the emulator) it crashes.. Ideas? the menu is called by the foolowing code: @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.menu , menu); return true; } - @Override public boolean onOptionsItemSelected(MenuItem item) { // Set up a new intent between the updater service and the main screen Intent options = new Intent(this, OptionsScreenActivity.class);

• Android: Strange out of memory issue

  - by Chrispix

  I am not sure where to start to explain this one. I have a list view with a couple image buttons on each row. When you click the list row, it launches a new activity. If you review some of my other posts, I have had to build my own tabs because of an issue w/ the camera layout. The activity that gets launched for result is a map. If I click on my button to launch the image preview (load an image off the sd card) the application returns from the activity back to the listview activity to the result handler to relaunch my new activity which is nothing more than an image widget. So here is the issue, the image preview on the list view is being done w/ the cursor & listadapter. This makes it pretty simple, but I am not sure how I can put a resized (i.e. smaller bit size not pixel) image as the src for the imgbutton on the fly. So I just resized the image that came off the phone camera. The issue is that I get an out of memory error when it tries to go back and re-launch the 2nd activity. ** My question : is there a way I can build the list adapter easily row by row, where I can resize on the fly (bit wise)? - this would be preferable as I also need to make some changes to the properties of the widgets/elements in each row as I am unable to select a row w/ touch screen b/c of focus issue. (I can use roller ball). ** I know I can do an out of band resize and save of my image, but that is not really what I want to do, but some sample code for that would be nice if that is your suggestion. As soon as I disabled the image on the listview it worked fine again. FYI : This is how I was doing it : String[] from = new String[] { DBHelper.KEY_BUSINESSNAME, DBHelper.KEY_ADDRESS, DBHelper.KEY_CITY, DBHelper.KEY_GPSLONG, DBHelper.KEY_GPSLAT, DBHelper.KEY_IMAGEFILENAME + ""}; to = new int[] { R.id.businessname, R.id.address, R.id.city, R.id.gpslong, R.id.gpslat, R.id.imagefilename }; notes = new SimpleCursorAdapter(this, R.layout.notes_row, c, from, to); setListAdapter(notes); Where R.id.imagefilename is a ButtonImage Here is my LogCat 01-25 05:05:49.877: ERROR/dalvikvm-heap(3896): 6291456-byte external allocation too

• ViewPager cycle between views?

  - by Erdem Azakli

• WPF Customized TabControl

  - by xsl

  I have to develop a customized tab control and decided to create it with WPF/XAML, because I planned to learn it anyway. It should look like this when it's finished: I made good progress so far, but there are two issues left: Only the first/last tab item should have a rounded upper-left/bottom-left corner. Is it possible to modify the style of these items, similar to the way I did with the selected tab item? The selected tab item should not have a border on its right side. I tried to accomplish this with z-index and overlapping, but the results were rather disappointing. Is there any other way to do this? XAML: <Window x:Class="MyProject.TestWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="TestWindow" Height="350" Width="500" Margin="5" Background="LightGray"> <Window.Resources> <Style TargetType="{x:Type TabControl}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type TabControl}"> <DockPanel> <Border Margin="0,100,-1,0" Background="#FFAAAAAA" BorderBrush="Gray" CornerRadius="7,0,0,7" BorderThickness="1"> <TabPanel Margin="0,0,0,0" IsItemsHost="True" /> </Border> <Border Background="WhiteSmoke" BorderBrush="Gray" BorderThickness="1" CornerRadius="7,7,7,0" > <ContentPresenter ContentSource="SelectedContent" /> </Border> </DockPanel> </ControlTemplate> </Setter.Value> </Setter> </Style> <Style TargetType="{x:Type TabItem}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type TabItem}"> <Grid> <Border Name="Border" Background="#FFAAAAAA" CornerRadius="7,0,0,0" BorderBrush="Gray" BorderThickness="0,0,0,1" Margin="0,0,0,0"> <ContentPresenter x:Name="ContentSite" VerticalAlignment="Center" HorizontalAlignment="Left" ContentSource="Header" Margin="10,10,10,10"/> </Border> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter TargetName="Border" Property="Background" Value="WhiteSmoke" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> </Window.Resources> <Grid> <TabControl Name="_menuTabControl" TabStripPlacement="Left" Margin="5"> <TabItem Name="_tabItem1" Header="First Tab Item" ></TabItem> <TabItem Name="_tabItem2" Header="Second Tab Item" > <Grid /> </TabItem> <TabItem Name="_tabItem3" Header="Third Tab Item" > <Grid /> </TabItem> </TabControl> </Grid>

• In WPF, how do I get a command in a Control Template to bind to a property in a parent?

  - by Keith

  I am relatively new to WPF and sometimes it makes my head explode. However, I do like the power behind it, especially when used with the MVVM model. I have a control template that contains a button. I use that control template inside of a custom control. I want to add a property on the custom control that will bind to the command property of the button inside the control template. Basically, it is a combo box with a button to the right of it to allow a user to pop up a search dialog. Since this control could appear on a usercontrol multiple times, I need to be able to potentially bind each control to a different command (Searh products, search customers, etc). However, I have been unable to figure out how to do this Here is some sample XAML <Style TargetType="{x:Type m:SelectionFieldControl}"> <Setter Property="LookupTemplate" Value="{StaticResource LookupTemplate}" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type m:SelectionFieldControl}"> <Border BorderThickness="{TemplateBinding Border.BorderThickness}" Padding="{TemplateBinding Control.Padding}" BorderBrush="{TemplateBinding Border.BorderBrush}" Background="{TemplateBinding Panel.Background}" SnapsToDevicePixels="True" Focusable="False"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto" MinWidth="0" SharedSizeGroup="{Binding LabelShareSizeGroupName, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type m:BaseFieldControl}}}" /> <ColumnDefinition Width="1*" /> <ColumnDefinition Width="Auto" SharedSizeGroup="{Binding WidgetsShareSizeGroupName, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type m:BaseFieldControl}}}" /> </Grid.ColumnDefinitions> <!-- Customized Value Part --> <ComboBox x:Name="PART_Value" Grid.Column="1" Margin="4,2,0,1" SelectedValue="{Binding Path=SelectionField.Value, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type m:SelectionFieldControl}}}" IsEnabled="{Binding Field.IsNotReadOnly, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type m:SelectionFieldControl}}}" Visibility="{Binding Field.IsInEditMode, Converter={StaticResource TrueToVisible}, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type m:SelectionFieldControl}}}" FontFamily="{StaticResource FontFamily_Default}" FontSize="11px"> <ComboBox.ItemsPanel> <ItemsPanelTemplate> <VirtualizingStackPanel IsVirtualizing="True" VirtualizationMode="Recycling"/> </ItemsPanelTemplate> </ComboBox.ItemsPanel> </ComboBox> <StackPanel Grid.Column="2" Orientation="Horizontal" Name="PART_Extra" Focusable="False"> <ContentControl Name="PART_LookupContent" Template="{Binding LookupTemplate, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type m:SelectionFieldControl}}}" Focusable="False"/> </StackPanel> </Grid> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> I thought I could get it to work by doing something like this <Button Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type SelectionFieldControl}}, Path=ShowSearchCommand}" Margin="2" /> but it does not work. Any help would be greatly appreciated.

• Refresh QTextEdit in PyQt

  - by Mark Underwood

  Hi all, Im writing a PyQt app that takes some input in one widget, and then processes some text files. What ive got at the moment is when the user clicks the "process" button a seperate window with a QTextEdit in it pops up, and ouputs some logging messages. On Mac OS X this window is refreshed automatically and you cna see the process. On Windows, the window reports (Not Responding) and then once all the proccessing is done, the log output is shown. Im assuming I need to refresh the window after each write into the log, and ive had a look around at using a timer. etc, but havnt had much luck in getting it working. Below is the source code. It has two files, GUI.py which does all the GUI stuff and MOVtoMXF that does all the processing.

• Partial view links not working in Fire Fox

  - by user329540

  I have a MVC4 asp.net application, I have two layouts a main layout for the main page and a second layout for the nested pages. The problem I have is with the second layout, on this layout I call a partial view which has my navigation links. In IE the navigation menu displays fine and when each item is clicked it navigates as expected. However in FF when the page renders the navigation bar is displayed but it has no 'click functionality' if you will its as if its simply text. My layout of nested page: <header> <img src="../../Images/fronttop.png" id="nestedPageheader" alt="Background Img"/> <div class="content-wrapper"> <section > <nav> <div id="navcontainer"> </div> </nav> </section> <div> </header> The script to retreive partial view and information for dynamic links on layout page. <script type="text/javascript"> var menuLoaded = false; $(document).ready(function () { if($('#navcontainer')[0].innerHTML.trim() == "") { $.ajax({ url: "@Url.Content("~/Home/MenuLayout")", type: "GET", success: function (response, status, xhr) { var nvContainer = $('#navcontainer'); nvContainer.html(response); menuLoaded = true; }, error: function (XMLHttpRequest, textStatus, errorThrown) { var nvContainer = $('#navcontainer'); nvContainer.html(errorThrown); } }); } }); </script> May partial view: @model Mscl.OpCost.Web.Models.stuffmodel <div class="menu"> <ul> <li><a>@Html.ActionLink("Home", "Index", "Home")</a></li> <li><a>@Html.ActionLink("some stuff", "stuffs", "stuff")</a></li> <li> <h5><a><span>somestuff</span></a></h5> <ul> <li><a>stuffs1s</a> <ul> @foreach (var image in Model.stuffs.Where(g => g.Grouping == 1)) { <li> <a>@Html.ActionLink(image.Title, "stuffs", "stuff", new { Id = image.CategoryId }, null)</a> </li> } </ul> </li> </ul> </il> </ul> </div> I need to know why this works fine in IE but why its not working in FF(all versions). Any assistance would be appreciated.

• How Do I Bind a "selected Item" in a Listbox to a ItemsControl in WPF?

  - by Scott

  LowDown: I am trying to create a Document Viewer in WPF. It will allow the user to preview selected documents and if they want, compare the documents in WPF. So they can view them side by side. The layout is this: Left side is a full list box. On the right side is a Collection or an Items control. Inside the items control will be a collection of the "selected documents" in the list box. So A user can select multiple items in the list box and for each new item they select, they can add the item to the collection on the right. I want the collection to look like a image gallery that shows up in Google/Bing Image searches. Make sense? The problem I am having is I can't get the WPFPreviewer to bind correctly to the selected item in the list box under the itemscontrol. Side Note: The WPFPreviewer is something Micorosft puts out that allows us to preview documents. Other previewers can be built for all types of documents, but im going basic here until I get this working right. I have been successful in binding to the list box WITHOUT the items control here: <Window.Resources> <DataTemplate x:Key="listBoxTemplate"> <StackPanel Margin="3" > <DockPanel > <Image Source="{Binding IconURL}" Height="30"></Image> <TextBlock Text=" " /> <TextBlock x:Name="Title" Text="{Binding Title}" FontWeight="Bold" /> <TextBlock x:Name="URL" Visibility="Collapsed" Text="{Binding Url}"/> </DockPanel> </StackPanel> </DataTemplate> </Window.Resources> <Grid Background="Cyan"> <ListBox HorizontalAlignment="Left" ItemTemplate="{StaticResource listBoxTemplate}" Width="200" AllowDrop="True" x:Name="lbDocuments" ItemsSource="{Binding Path=DocumentElements,ElementName=winDocument}" DragEnter="documentListBox_DragEnter" /> <l:WPFPreviewHandler Content="{Binding ElementName=lbDocuments, Path=SelectedItem.Url}"/> </Grid> Though, once I add in the ItemsControl, I can't get it to work anymore: <Window.Resources> <DataTemplate x:Key="listBoxTemplate"> <StackPanel Margin="3" > <DockPanel > <Image Source="{Binding IconURL}" Height="30"></Image> <TextBlock Text=" " /> <TextBlock x:Name="Title" Text="{Binding Title}" FontWeight="Bold" /> <TextBlock x:Name="URL" Visibility="Collapsed" Text="{Binding Url}"/> </DockPanel> </StackPanel> </DataTemplate> </Window.Resources> <Grid> <ListBox HorizontalAlignment="Left" ItemTemplate="{StaticResource listBoxTemplate}" Width="200" AllowDrop="True" x:Name="lbDocuments" ItemsSource="{Binding Path=DocumentElements,ElementName=winDocument}" DragEnter="documentListBox_DragEnter" /> <ItemsControl x:Name="DocumentViewer" ItemsSource="{Binding ElementName=lbDocuments, Path=SelectedItem.Url}" > <ItemsControl.ItemTemplate> <DataTemplate> <Grid Background="Cyan"> <l:WPFPreviewHandler Content="{Binding Url}"/> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> </Grid> Can someone please help me out with trying to bind to the ItemsControl if I select one or even multiple items in the listbox.

• DTGridView losing content while scrolling

  - by Wim Haanstra

  I am using DTGridView from the DTKit by Daniel Tull. I implemented it in a very simple ViewController and the test I am doing is to place a button in the last row of the grid, which should add another row to the grid (and therefor moving the button to a row beneath it). The problem is, when I click the button a couple of times and then start scrolling, the grid seems to lose its content. As I am not completly sure this is a bug in the grid, but more in my code, I hope you guys can help me out and track down the bug. First I have my header file, which is quite simple, because this is a test: #import <UIKit/UIKit.h> #import "DTGridView.h" @interface TestController : UIViewController <DTGridViewDelegate, DTGridViewDataSource> { DTGridView* thumbGrid; } @end I declare a DTGridView, which will be my grid, where I want to put content in. Now, my code file: #import "TestController.h" @implementation TestController int rows = 1; - (NSInteger)numberOfRowsInGridView:(DTGridView *)gridView { return rows; } - (NSInteger)numberOfColumnsInGridView:(DTGridView *)gridView forRowWithIndex:(NSInteger)index { if (index == rows - 1) return 1; else return 3; } - (CGFloat)gridView:(DTGridView *)gridView heightForRow:(NSInteger)rowIndex { return 57.0f; } - (CGFloat)gridView:(DTGridView *)gridView widthForCellAtRow:(NSInteger)rowIndex column:(NSInteger)columnIndex { if (rowIndex == rows - 1) return 320.0f; else return 106.6f; } - (DTGridViewCell *)gridView:(DTGridView *)gridView viewForRow:(NSInteger)rowIndex column:(NSInteger)columnIndex { DTGridViewCell *view = [[gridView dequeueReusableCellWithIdentifier:@"thumbcell"] retain]; if (!view) view = [[DTGridViewCell alloc] initWithReuseIdentifier:@"thumbcell"]; if (rowIndex == rows - 1) { UIButton* btnLoadMoreItem = [[UIButton alloc] initWithFrame:CGRectMake(10, 0, 301, 57)]; [btnLoadMoreItem setTitle:[NSString stringWithFormat:@"Button %d", rowIndex] forState:UIControlStateNormal]; [btnLoadMoreItem.titleLabel setFont:[UIFont boldSystemFontOfSize:20]]; [btnLoadMoreItem setBackgroundImage:[[UIImage imageNamed:@"big-green-button.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0] forState:UIControlStateNormal]; [btnLoadMoreItem addTarget:self action:@selector(selectLoadMoreItems:) forControlEvents:UIControlEventTouchUpInside]; [view addSubview:btnLoadMoreItem]; [btnLoadMoreItem release]; } else { UILabel* label = [[UILabel alloc] initWithFrame:CGRectMake(10,0,100,57)]; label.text = [NSString stringWithFormat:@"%d x %d", rowIndex, columnIndex]; [view addSubview:label]; [label release]; } return [view autorelease]; } - (void) selectLoadMoreItems:(id) sender { rows++; [thumbGrid setNeedsDisplay]; } - (void)viewDidLoad { [super viewDidLoad]; thumbGrid = [[DTGridView alloc] initWithFrame:CGRectMake(0,0, 320, 320)]; thumbGrid.dataSource = self; thumbGrid.gridDelegate = self; [self.view addSubview:thumbGrid]; } - (void)viewDidUnload { [super viewDidUnload]; } - (void)dealloc { [super dealloc]; } @end I implement all the methods for the DataSource, which seem to work. The grid is filled with as many rows as my int 'rows' ( +1 ) has. The last row does NOT contain 3 columns, but just one. That cell contains a button which (when pressed) adds 1 to the 'rows' integer. The problem starts, when it starts reusing cells (I am guessing) and content start disappearing. When I scroll back up, the UILabels I am putting in the cells are gone. Is there some bug, code error, mistake, dumb-ass-move I am missing here? Hope anyone can help.

• Custom animation problem in Powerpoint 2003

  - by Tom Gullen

  I have an animation of a grid that scrolls to the left. It's a Gantt chart, and it works fine. I then have several elements I want to drop on the grid, I give them all the same movement animation and this works fine, everything scrolls at the same speed and time. However I want to add entrance animations for the elements on the grid, I can have it so that when all the entrance animations are complete then it starts scrolling, but I want it to enter whilst it is scrolling. How do you have an entrance animation for an element and keep it's position updated? The entrance animation and movement animation don't seem to work together as expected when run simultaneously. cheers!

• xkb layouts not working (in KDE?) after upgrade from Ubuntu 9.10 to 10.04

  - by Alan

  I customised my keyboard layout in 9.10 by editing the appropriate /usr/share/X11/xkb/symbols/ file. After upgrading to 10.04 I noticed it had overwritten all my modifications, so I recovered the layout and overwrote the symbol file's base entry. Sadly KDE (and, presumably, the entire OS) seems to ignore the files altogether. The help files don't mention anything about modifying layouts anyway (and the layout switcher seems to be using setxkbmap, which uses the above path according to its man page), so I'm at a bit of a loss. Do I need to compile this into some other format somehow or how do I get it to work?

• Can I keep columns from breaking across pages?

  - by Jakob

  In Microsoft Word 2007, if I put a passage of text into a column layout that spans two pages, Word first puts everything that fits on the first page into a column layout on the first page, then the rest into a column layout on the second page. I want to prevent this breaking. The question is difficult to phrase, so here's an example of what I want to accomplish: Instead of a c e b d f ----- g j m h k n i l o I want the columns to be preserved across the page break, like so: a f k b g l ----- c h m d i n e j o Is this possible in Microsoft Word 2007?

• Formatting Telerik Chart and Legend Labels in Silverlight

  - by Bryan

  I am trying to format a column called 'Month' using the 3-character month abbreviation in my data grid which is bound to a bar chart. My grid and chart are based on this demo example: http://demos.telerik.com/silverlight/#Chart/Aggregates. Basically, the grid compiles data and summarizes by Year, Quarter, Month, and then some other categories as well. For the Month column, I tried two different methods (for sorting purposes, I have to use an integer or some date value for the month). First, I just made Month an integer field and then used a converter mapped in the xaml for the 'Month' field to display 'JAN', 'FEB', etc. This worked fine for the grid, but the chart would display 1, 2, etc. instead of the month abbreviation. I researched this and was not able to come up with a solution to map the converter to the chart. So, I tried making the Month field a datetime and then set the value to 1/1/1900, 2/1/1900, etc. and specified the format of the field to 'MMM' in the xaml for the grid. I then used the following statement to set the the format in the chart when the user grouped by month: SalesAnalysisChart.DefaultView.ChartArea.AxisX.DefaultLabelFormat = "MMM"; This partially worked in that when the months were displayed across the x-axis they were labeled properly, but not when they appeared in the legend (the user, of course, can group by any of the columns which may or may not include month). I've tried setting LegendItemLabelFormat, ItemLabelFormat, etc. but without success. I'm not sure of the element on which to set the property. I only need to change the default format for just the Month column - all other columns should display normally when grouped. I also came across a class called 'LegendItemFormatConverter' which looks promising but I can't find any examples as to how to implement it. I would actually prefer the converter method because the converter I wrote displays the month abbreviation in all caps, whereas the 'MMM' format displays in upper/lower case. Here is the converter code that I originally used for the grid: using System; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Ink; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; using System.Windows.Data; namespace ApolloSL { public class MonthConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { if (value != null) { DateTime date = new DateTime(1900, (Int32)value, 1); return date.ToString("MMM").ToUpper(); } else { return ""; } } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { return value.ToString(); } } } Please help... Thanks in advance for your assistance, Bryan
