  • Setting Position of NSWindow before Display

    - by Armin Ronacher
    Right now I'm setting the position of a window that is about to open like this: -(void) setActiveNodeDialog:(ISKNodeDialogController *)dialog { if (activeNodeDialog) [[activeNodeDialog window] close]; activeNodeDialog = dialog; if (activeNodeDialog) { [activeNodeDialog setMainWindowController:self]; NSRect windowRect = [[self window] frame]; NSRect dialogRect = [[activeNodeDialog window] frame]; NSPoint pos; pos.x = windowRect.origin.x + windowRect.size.width - dialogRect.size.width - 10; pos.y = windowRect.origin.y + 32; [[activeNodeDialog window] setFrameOrigin:pos]; [[activeNodeDialog window] makeKeyAndOrderFront:nil]; } } The problem with that is, that the window will "jump" when shown. And that even though I set the position before showing the window with "makeKeyAndOrderFront". The window is a NSPanel *. Anyone any ideas how to fix the jumping? Setting the position in awakeFromNib is not an option because the main controller is set later.

  • can these templates be made unambiguous

    - by R Samuel Klatchko
    I'm trying to create a set of overloaded templates for arrays/pointers where one template will be used when the compiler knows the size of the array and the other template will be used when it doesn't: template <typename T, size_t SZ> void moo(T (&arr)[SZ]) { ... } template <typename T> void moo(T *ptr) { ... } The problem is that when the compiler knows the size of the array, the overloads are ambiguous and the compile fails. Is there some way to resolve the ambiguity (perhaps via SFINAE) or is this just not possible.

  • Scaling larger Image problem.

    - by krishna
    Hi, I m developing flex application, in which I want to Draw Image from User local hard-drive to the canvas of size 640x360. User can choose Image of bigger resolution & is scaled to Canvas size. But if user selected images of larger resolution like 3000x2000, the scaling take lot time & freezes the application until scale done. Is there any method to scale image faster or kind of threading can be done? I am using matrix to scale Image as below: var mat:Matrix = new Matrix(); var scalex:Number = canvasScreen.width/content.width; var scaley:Number = canvasScreen.height/content.height; mat.scale(scalex,scaley); canvasScreen.graphics.clear(); canvasScreen.graphics.beginBitmapFill(content.bitmapData,mat);

  • AsyncListViewAdapter + SimplePager, why is inactive pager clearing the table?

    - by Jaroslav Záruba
    I'm trying to make CellTable work together with AsyncListViewAdapter<T> and SimplePager<T>. The data gets displayed, but when the pager should be 'deaf' (meaning when all existing data are displayed) it still receives clicks and, more importantly, makes the displayed data go away. Instead of my data 'loading' indicator gets displayed, and it keep loading and loading... Obviously nothing gets loaded, as it doesn't even call the onRangeChanged handler. I went through the code-snippets in this thread, but I can't see anything suspicions on what I've been doing. Is there some obvious answer to a rookie mistake? I shrinked my variable names, hopefully it won't wrap too much. protected class MyAsyncAdapter extends AsyncListViewAdapter<DTO> { @Override protected void onRangeChanged(ListView<DTO> v) { /* * doesn't even get called on [go2start/go2end] click :( */ Range r = v.getRange(); fetchData(r.getStart(), r.getLength()); } } private void addTable() { // table: CellTable<DTO> table = new CellTable<DTO>(10); table.addColumn(new Column<DTO, String>(new TextCell()) { @Override public String getValue(DTO myDto) { return myDto.getName(); } }, "Name"); // pager: SimplePager<DTO> pager = new SimplePager<DTO>(table); table.setPager(pager); adapter = new MyAsyncAdapter(); adapter.addView(table); // does not make any difference: // adapter.updateDataSize(0, false); // adapter.updateDataSize(10, true); VerticalPanel vPanel = new VerticalPanel(); vPanel.add(table); vPanel.add(pager); RootLayoutPanel.get().add(vPanel); } // success-handler of my fetching AsyncCallback @Override public void onSuccess(List<DTO> data) { // AsyncCallback<List<DTO>> has start field adapter.updateViewData(start, data.size(), data); if(data.size() < length) adapter.updateDataSize(start + data.size(), true); } Regards J.

  • tcpdf - HTML table showing up way too small

    - by LinuxGnut
    Hi folks. I'm using tcpdf (http://www.tcpdf.org/) to generate PDFs of some tables and images. The images are loaded without an issue, but I'm having issues with the writeHTML() function. I can't seem to control the font sizes or table width/height through the HTML, so I end up with a tiny, tiny, tiny table that you have to print of and squint at to even attempt reading. I've tried editing the table itself, CSS, even putting the table itself inside an h1, but nothing is changing the font size. I have the font size in tcpdf set to 16, but this also has no affect. Has anyone else run into this issue?

    - by dole
    Hi there As far i know until now, the min version of a .js(javascript) file is obtaining by removing the unncessary blank spaces and comments, in order to reduce the file size. My questions are: How can I convert a min.js file into a clear, easy readable .js file Besides, size(&and speed) are there any other advtages of the min.js file. the js files can be encripted? can js be infected. I think the answer is yes, so the question is how to protect the .js files from infections? Only the first question is most important and I'm looking for help on it. TY

  • Developing "Command Line" in .NET?

    - by Sergey Malyan
    Imagine a "search box" on the right top side of the UI Windows Application. When user types a desired action, a matching functionality is executed. Screen gets opened, or action gets performed. For example: user types "create" and intellisence offered next word options "client"/"product", user picks "client", and "Create New Client" screen opens up. So what I am looking for if there is a framework support for this. I assume that framework shall bind together text commands names, commands and show in intellisense. Same framework possibly could have been used in alternative "Command Line interface". I recall Microsoft had some recent framework that helps to setup "command Line Interface" environmental. It is hard to search on web for this keywords, so relying on intelligent help from you guys. Thanks in advance.

  • Ignore carriage returns in scanf before data.... to keep layout of console based graphics with conio

    - by volting
    I have the misfortune of having use conio.h in vc++ 6 for a college assignment, My problem is that my graphic setup is in the center of the screen... e.g. gotoxy( getcols()/2, getrows()/2); printf("Enter something"); scanf( "%d", &something ); now if someone accidentally hits enter before they enter the "something", then the cursor gets reset to the left of the screen on the next line. Iv tried flushing the keyboard and bios buffers with fflush(stdin) and getchar(), which like I expected didn't work! Any help/ideas would be appreciated, Thanks, V

  • Strict pointer aliasing: any solution for a specific problem?

    - by doublep
    I have a problem caused by breaking strict pointer aliasing rule. I have a type T that comes from a template and some integral type Int of the same size (as with sizeof). My code essentially does the following: T x = some_other_t; if (*reinterpret_cast <Int*> (&x) == 0) ... Because T is some arbitary (other than the size restriction) type that could have a constructor, I cannot make a union of T and Int. (This is allowed only in C++0x only and isn't even supported by GCC yet). Is there any way I could rewrite the above pseudocode to preserve functionality and avoid breaking strict aliasing rule? Note that this is a template, I cannot control T or value of some_other_t; the assignment and subsequent comparison do happen inside the templated code. (For the record, the above code started breaking on GCC 4.5 if T contains any bit fields.)

  • Listview icons show up blurry (C#)

    - by Balk
    I'm attempting to display a "LargeIcon" view in a listview control, however the images I specify are blurry. This is what I have so far: The .png files are 48x48 and that's what I have it set to display at in the ImageList properties. There's one thing that I've noticed (which is probably the cause) but I don't know how to change it. Inside the "Images Collection Editor" where you choose what images you want for the ImageList control, it looks like it's setting the wrong size for each image. As you can see the "PhysicalDimension" and the "Size" is set to 16x16 and not abled to be manipulated. Does anyone have any ideas? Many thanks!

  • jquery form validation

    - by kalpaitch
    I am using jquery for a quick and easy form validation My forms use the input's default value as a label and I have a little onfocus and onblur javascript function to show and hide this when the user starts to type: <input name='fnameREG' type='text' id='fnameREG' value='first name' size='70' onfocus='clearInput(this)' onblur='clearInput(this)' /> <input name='lnameREG' type='text' id='lnameREG' value='last name' size='70' onfocus='clearInput(this)' onblur='clearInput(this)' /> My issue with the validation is that when the submit button is clicked the pluggin thinks that all the fields are set because they have a default value. I looked but I couldn't find a supplied method to get round this. Thanks!

  • Java memory mapped files and swap

    - by MarkS
    I'm looking at some memory mapped files in Java. Let's say I have a heap size set to 2gb, and I memory map a file that is 50gb - far more than the physical memory on the machine. The OS will cache parts of that 50gb file in the os file cache, the java process will have 2gb of heap space. What I'm curious about is how does the OS decide how much of the 50gb file to cache? For instance, if I have another java process, also with a 2gb heap size, will that 2gb be swapped out to allow the os to cache parts of the memory mapped file? Will parts of the heap space of the first process be swapped out to allow the OS to cache? Is there any way to tell the OS not to swap heap space for OS caching? If the OS doesn't swap out main processes, how does it determine how big its file cache should be?

  • Does a program exist for checking two similar directories for file differences?

    - by John Sullivan
    Is there a program to compare one folder and all subfolders to another folder and all subfolders for differences in the files contained therein (presence, absence of files, size and list of filenames)? Example of usage: I have 100 DLL files from environment 1 and I want to check if any of them are different (in size and date modified) from the 100 DLL files in environment 2. So I copy and paste all the DLLs in environment 1 into directory A, and all the DLLs in environment 2 into directory B. I then run my "directory comparison" program on directories A and B and find out that, aha, here is a list of 7 DLLs that have different modified dates and times between the two directories. EDIT: OS is windows XP

  • I am not able launch JNLP aaplications using "Java Web Start"?

    - by akjain
    Up until recently, I was able to launch/open JNLP files in Firefox using Java web start. Don't know what happened all of a sudden JNLP files stopped launching, a splash screen appears saying Java Starting... and then nothing happens. Even the Java Console in the browser and javacpl.cpl applet doesn't open. Tried all possibilities: removed all older version and installed the latest JRE (java version "1.6.0_17"), still it doesn't work. Done some googling for this problem, people suggested to start javaws.exe with -viewer option but same behavior (a splash screen appears saying "Java Starting..." and then disappears) The problem is that I don't know any place (logs etc.) to look for to see what is causing the problem. I am using WinXP SP3, and some of the screenshots below shows further info about my system. I can provide any other detail if required but please help me solve this problem. Update: Although this question is bit old, Following solution fixed above issue for me (indeed this was the actual cause)

  • How can I change GWT's widget CSS values?

    - by Xorty
    Basically, I like default theme widgets. However, I need to change font size on DecoratedStackPanel widget. I think it should be possible with something like this: decoratedStackPanel.getElement().getStyle().setProperty("fontSize", "12pt"); However, "fontSize" is not valid name for property and I didn't find way how to get all element's properties. Therefore, I don't know correct property name. Any ideas? Please, don't post about inheriting widget or writing custom CSS. I like default one but the font size. This should be possible afaik.

  • WPF - Listbox bound to collection acts as one item

    - by user553765
    Hi, I have a listbox with the ItemsControl binding the ItemsSource to a readonly collection of strings. The ItemTemplate then declares the DataTemplate as a checkbox where its content is that of the name of the particular item in the collection and IsChecked bound to a property to determine whether or not the item is selected (it's just a listbox of checkboxes) This works fine with one exception - MouseOver the ListBox and it acts as if the collection of Strings is a single item; the whole box acts as if selected. This wouldn't be as much of a problem were it not for this also affecting the scrollbars where they won't get enabled - presumably because it considers the one item as being visible on the screen even though it in actual facts is x+ with only x-y showing on the screen. How do I get the listbox to act as if each individual string is its own item. I assume it acts this way because I declared a datatemplate in order to get a listbox of checkboxes?? Any help would be much appreciated!

  • CellTable + AsyncListViewAdapter<T>, stuck at 'loading' when paging

    - by Jaroslav Záruba
    Hi I'm trying to make CellTable, AsyncListViewAdapter<T> and SimplePager<T> working together. I managed to display my data, but whenever I click either "go to start" or "go to end" button I get that 'loading' indicator which stays there till the end of days. ( AsyncListViewAdapter<T>.onRangeChanged doesn't even get called this time.) As I have only single row in my data those two buttons should be (and appear to be) disabled. I went through the code-snippets in this thread, but I can't see nothing suspicions in what I've been doing. Is there some obvious answer to a rookie mistake? I shrinked my variable names, hopefully it won't wrap too much. protected class MyAsyncAdapter extends AsyncListViewAdapter<DTO> { @Override protected void onRangeChanged(ListView<DTO> v) { // doesn't get called on go2start/go2end :( Range r = v.getRange(); fetchData(r.getStart(), r.getLength()); } } private void addTable() { // table: CellTable<DTO> table = new CellTable<DTO>(10); table.addColumn(new Column<DTO, String>(new TextCell()) { @Override public String getValue(DTO namespace) { return namespace.getName(); } }, "Name"); // pager: SimplePager<DTO> pager = new SimplePager<DTO>(table); table.setPager(pager); adapter = new MyAsyncAdapter(); adapter.addView(table); // does not make any difference: // adapter.updateDataSize(0, false); // adapter.updateDataSize(10, true); VerticalPanel vPanel = new VerticalPanel(); vPanel.add(table); vPanel.add(pager); RootLayoutPanel.get().add(vPanel); } // success-handler of my fetching AsyncCallback @Override public void onSuccess(List<DTO> data) { // AsyncCallback<List<DTO>> has start field adapter.updateViewData(start, data.size(), data); if(data.size() < length) adapter.updateDataSize(start + data.size(), true); } Regards J.

  • How to prevent modal view controllers flashing when changing

    - by KP Overflow
    I have three view controllers, let's call them A, B and C. When a button is pressed on view A, view B is shown using presentModalViewController:animated: When the finish button is pressed on screen B, it dismisses itself. View A is notified whereupon it immediately shows view C, again using presentModalViewController:animated: The problem is that view A's content is momentarily flashed on the screen between view B closing and view C opening. I can get around this by making view A blank and moving it's current content to a new view, D. (For various reasons, I don't want view B to own view C, that's why it's not opening it) Am I over-complicating this? I'm sure there is a smarter way to go? ThanksT

  • How to detect an 'image area' percentage inside an image?

    - by DaNieL
    Mhh, kinda hard to explain with my poor english ;) So, lets say I have an image, doesnt matter what kind of (gif, jpg, png) with 200x200 pixel size (total area 40000 pixels) This image have a background, that can be trasparent, or every color (but i know the background-color in advance). Lets say that in the middle of this image, there is a picture (for keep the example simple lets suppose is a square drawn), of 100x100 pixels (total area 10000 pixels). I need to know the area percentage that the small square fill inside the image. So, in i know the full image size and the background-color, there is a way in php/python to scan the image and retrieve that (in short, counting the pixel that are different from the given background)? In the above example, the result should be 25%

  • How to create a compact Qt4 vBoxLayout

    Hello all, I've got a vBoxLayout which contains 3 simple buttons, when I increase the size of the widget containing the layout, the spacing between the buttons increases. I would like to stop this behaviour and keep the buttons in a consistent and compact layout, regardless of the size of the parent widget. This is what I've got so far, but it doesn't change the spacing, any suggestions?, thanks. button_layout = new QVBoxLayout ; button_layout -> setSpacing(0); button_layout -> setContentsMargins(0,0,0,0);

  • I'm working on a website that sells different artwork, what's the best way to handle different image

    - by ThinkingInBits
    I'm working on a website that will allow users to upload and sell their artwork in different sizes. I was wondering what the best way would be to handle the different file sizes automatically. A few points I was curious on: How to define different size categories (small, medium, large) in such a way that I'll be able to dynamically re-size images with proportional dimensions. Should I store actual jpegs of the different sizes for download? Or would it be easier to generate these different sizes for download on the fly My thumbnails will be somewhat larger than your average thumbnails, should I store a second 'thumbnail image' with the sites watermark overlaying it? Or once again, generate this on the fly? All opinions, advice are greatly appreciated!
