  • Trouble getting QMainWindow to scroll

    - by random
    A minimal example: class MainWindow(QtGui.QMainWindow): def __init__(self, parent = None): QtGui.QMainWindow.__init__(self, parent) winWidth = 683 winHeight = 784 screen = QtGui.QDesktopWidget().availableGeometry() screenCenterX = (screen.width() - winWidth) / 2 screenCenterY = (screen.height() - winHeight) / 2 self.setGeometry(screenCenterX, screenCenterY, winWidth, winHeight) layout = QtGui.QVBoxLayout() layout.addWidget(FormA()) mainWidget = QtGui.QWidget() mainWidget.setLayout(layout) self.setCentralWidget(mainWidget) FormA is a QFrame with a VBoxLayout that can expand to an arbitrary number of entries. In the code posted above, if the entries in the forms can't fit in the window then the window itself grows. I'd prefer for the window to become scrollable. I've also tried the following... replacing mainWidget = QtGui.QWidget() mainWidget.setLayout(layout) self.setCentralWidget(mainWidget) with mainWidget = QtGui.QScrollArea() mainWidget.setLayout(layout) self.setCentralWidget(mainWidget) results in the forms and entries shrinking if they can't fit in the window. Replacing it with mainWidget = QtGui.QWidget() mainWidget.setLayout(layout) scrollWidget = QtGui.QScrollArea() scrollWidget.setWidget(mainWidget) self.setCentralWidget(scrollWidget) results in the mainwidget (composed of the forms) being scrunched in the top left corner of the window, leaving large blank areas on the right and bottom of it, and still isn't scrollable. I can't set a limit on the size of the window because I wish for it to be resizable. How can I make this window scrollable?

  • android: getting rid of "warning: unmappable character for encoding ascii"

    - by Lo'oris
    I'm compiling using android tools without eclipse. I compile launching "ant debug" from command line. I have found many many instructions around the web about how to remove with annoying warning, but I haven't been able to make any of them work. I've tried -D option, I've tried randomly tweaking build.* files, I've tried exporting an environment variable... nothing. I guess some of these methods just don't work, and some others would work but I've been doing them incorrectly. Anything is possible and I can't stand it any more: any advice on how to do it?

  • Getting unevaluated tcl arguments

    - by user1327792
    What I want to do is parse an argument to a tcl proc as a string without any evaluation. For example if I had a trivial proc that just prints out it's arguments: proc test { args } { puts "the args are $args" } What I'd like to do is call it with: test [list [expr 1+1] [expr 2+2]] And NOT have tcl evaluate the [list [expr 1+1] [expr 2+2]]. Or even if it evaluated it I'd still like to have the original command line. Thus with the trivial "test" proc above I'd like to be able to return: the args are [list [expr 1+1] [expr 2+2]] Is this possible in tcl 8.4 ? Thank you. -MP

  • Getting age in years in a SQL query

    - by Earlz
    Hello I've been tasked with doing a few queries on a large SQL Server 2000 database. The query I'm having trouble with is "find the number of people between ages 20 and 40" How would I do this? My previous query to get a count of everyone looks like this: select count(rid) from people where ... (with the ... being irrelevant conditions). I've googled some but the only thing I've found for calculating age is so large that I don't see how to embed it into a query, or it is a stored procedure which I do not have the permissions to create. Can someone help me with this?

  • User control events not getting to their handlers

    - by PhrkOnLsh
    I am trying to create a user control to wrap around the Membership API (A set of custom Gridviews to display the data better) and, while the code and the controls worked fine in the page, when I moved them to an .ascx, the events stopped firing to it. <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="CustomMembership.ascx.cs" Inherits="CCGlink.CustomMembership" %> <asp:Panel ID="mainPnl" runat="server"> <asp:Label id="lblError" ForeColor="Red" Font-Bold="true" runat="server" /> <asp:GridView id="grdUsers" HeaderStyle-cssclass="<%# _headercss %>" RowStyle-cssclass="<%# _rowcss %>" AlternatingRowStyle-cssclass="<%# _alternatingcss %>" OnRowUpdating="grdUsers_RowUpdating" OnRowDeleting="grdUsers_RowDeleting" OnRowCancelingEdit="grdUsers_cancelEdit" autogeneratecolumns="false" allowsorting="true" AllowPaging="true" EmptyDataText="No users..." pagesize="<%# PageSizeForBoth %>" runat="server"> <!-- ...columns... --> </asp:GridView> <asp:Button id="btnAllDetails" onclick="btnAllDetails_clicked" text="Full Info" runat="server" /> <asp:GridView DataKeyNames="UserName" HeaderStyle-cssclass="<%# _headercss %>" RowStyle-cssclass="<%# _rowcss %>" AlternatingRowStyle-cssclass="<%# _alternatingcss %>" id="grdAllDetails" visible="false" allowsorting="true" EmptyDataText="No users in DB." pagesize="<%# PageSizeForBoth %>" runat="server" /> <asp:Button id="btnDoneAllDetails" onclick="btnAllDetails_clicked" text="Done." Visible="false" runat="server" /> </asp:Panel> However, none of the events in the first two controls (the gridview grdUsers and the button btnAllDetails) simply do NOT occur, I have verified this in the debugger. If they occured just fine in the aspx page, why do they die on moving to the ascx? My code in the aspx now is: <div class="admin-right"> <asp:ScriptManager ID="sm1" runat="server" /> <h1>User Management</h1> <div class="admin-right-users"> <asp:UpdatePanel ID="up1" runat="server"> <ContentTemplate> <cm1:CustomMembership id="showUsers" PageSizeForBoth="9" AlternatingRowStylecssclass="alternating" RowStylecssclass="row" DataSource="srcUsers" HeaderStylecssclass="header" runat="server" /> </ContentTemplate> </asp:UpdatePanel> </div> Thanks.

  • Ajax response seems to be getting lost

    - by Ringo Blancke
    I'm using the ddslick jquery dropdown plugin in conjunction with my Rails app. In view1, I have $('#challenges_dropdown').ddslick({ <snipped> onSelected: function (data) { $.ajax({ url: "/load_data", type: "GET", data: {"id": data.selectedData.value} }); } }); I.e., I make a call to my controller to load_data. The controller receives this correctly and then at the end, makes a call to render a separate view render "data" This view contains a script snippet that needs to run in order to update some elements of my original view. For some reason, this script snippet is just not running. I'm very confused. When I use a regular link with data-remote="true", then the whole process works perfectly. However, when I make an AJAX call, it fails. What's going on?? Thanks! Ringo

  • Getting req.params in order in Express JS

    - by Adam Terlson
    In Express, is there a way to get the arguments passed from the matching route in the order they are defined in the route? I want to be able to apply all the params from the route to another function. The catch is that those parameters are not known up front, so I cannot refer to each parameter by name explicitly. app.get(':first/:second/:third', function (req) { output.apply(this, req.mysteryOrderedArrayOfParams); // Does this exist? }); function output() { for(var i = 0; i < arguments.length; i++) { console.log(arguments[i]); } } Call on GET: "/foo/bar/baz" Desired Output (in this order): foo bar baz

  • Getting automatic matching brace in vim

    - by Bob
    I spend WAY to much time fumbling around because vim doesn't handle closing braces like most IDEs do. Here's what I want to happen: type this: if( whatever ) { <CR> where <CR> mean hit the enter key and get this: if( whatever ) { | } where | is the position of the cursor. It's what Eclipse does. It's what Visual Studio does. And it's what I want Vim to do. I've seen a few plugins, tried a few, and none of them seem to give me this behavior. Surely I can't be the first programmer to want this.

  • Backing Bean not getting values sent by javascript

    - by Developer106
    I have three drop down lists whose values are been copied to <h:inputHidden> components by the following JavaScript function: function getBirthDate() { var months = document.getElementById("months") var hidden1 = document.getElementById("formsignup:monthField"); hidden1.value = months.options[months.selectedIndex].text; var days = document.getElementById("days"); var hidden2 = document.getElementById("formsignup:dayField"); hidden2.value = days.options[days.selectedIndex].value; var years = document.getElementById("years"); var hidden3 = document.getElementById("formsignup:yearField"); hidden3.value = years.options[years.selectedIndex].value; } Here are the three <h:inputHidden> components: <h:inputHidden value="#{signupBean.month}" id="monthField"/> <h:inputHidden value="#{signupBean.day}" id="dayField"/> <h:inputHidden value="#{signupBean.year}" id="yearField"/> This is the command button that is supposed to invoke the function that copies the values to the inputs and then submits them to the backing bean. <h:commandButton image="images/images/signup1.png" styleClass="joinnow" id="joinus" action="#{signupBean.save}" onclick="getBirthDate()" /> But they arrive as null in the backing bean. How is this caused and how can I solve it?

  • Getting scp's status bar to appear in a Java window

    - by pete
    I'm writing a program that uses scp to copy files in a bigger java program. As it stands now, the program freezes up while the scp is copying the file, which can take a few minutes, so I'd like to be able to display the progress of the scp or at the very least get the terminal window with the scp progress to show up! Any suggestions?

  • 4 table query / join. getting duplicate rows

    - by Horse
    So I have written a query that will grab an order (this is for an ecommerce type site), and from that order id it will get all order items (ecom_order_items), print options (c_print_options) and images (images). The eoi_p_id is currently a foreign key from the images table. This works fine and the query is: SELECT eoi_parentid, eoi_p_id, eoi_po_id, eoi_quantity, i_id, i_parentid, po_name, po_price FROM ecom_order_items, images, c_print_options WHERE eoi_parentid = '1' AND i_id = eoi_p_id AND po_id = eoi_po_id; The above would grab all the stuff I need for order #1 Now to complicate things I added an extra table (ecom_products), which needs to act in a similar way to the images table. The eoi_p_id can also point at a foreign key in this table too. I have added an extra field 'eoi_type' which will either have the value 'image', or 'product'. Now items in the order could be made up of a mix of items from images or ecom_products. Whatever I try it either ends up with too many records, wont actually output any with eoi_type = 'product', and just generally wont work. Any ideas on how to achieve what I am after? Can provide SQL samples if needed? SELECT eoi_id, eoi_parentid, eoi_p_id, eoi_po_id, eoi_po_id_2, eoi_quantity, eoi_type, i_id, i_parentid, po_name, po_price, po_id, ep_id FROM ecom_order_items, images, c_print_options, ecom_products WHERE eoi_parentid = '9' AND i_id = eoi_p_id AND po_id = eoi_po_id The above outputs duplicate rows and doesnt work as expected. Am I going about this the wrong way? Should I have seperate foreign key fields for the eoi_p_id depending it its an image or a product? Should I be using JOINs? Here is a mysql explain of the tables in question ecom_products +-------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-------------+--------------+------+-----+---------+----------------+ | ep_id | int(8) | NO | PRI | NULL | auto_increment | | ep_title | varchar(255) | NO | | NULL | | | ep_link | text | NO | | NULL | | | ep_desc | text | NO | | NULL | | | ep_imgdrop | text | NO | | NULL | | | ep_price | decimal(6,2) | NO | | NULL | | | ep_category | varchar(255) | NO | | NULL | | | ep_hide | tinyint(1) | NO | | 0 | | | ep_featured | tinyint(1) | NO | | 0 | | +-------------+--------------+------+-----+---------+----------------+ ecom_order_items +--------------+-------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +--------------+-------------+------+-----+---------+----------------+ | eoi_id | int(8) | NO | PRI | NULL | auto_increment | | eoi_parentid | int(8) | NO | | NULL | | | eoi_type | varchar(32) | NO | | NULL | | | eoi_p_id | int(8) | NO | | NULL | | | eoi_po_id | int(8) | NO | | NULL | | | eoi_quantity | int(4) | NO | | NULL | | +--------------+-------------+------+-----+---------+----------------+ c_print_options +------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------+--------------+------+-----+---------+----------------+ | po_id | int(8) | NO | PRI | NULL | auto_increment | | po_name | varchar(255) | NO | | NULL | | | po_price | decimal(6,2) | NO | | NULL | | +------------+--------------+------+-----+---------+----------------+ images +--------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +--------------+--------------+------+-----+---------+----------------+ | i_id | int(8) | NO | PRI | NULL | auto_increment | | i_filename | varchar(255) | NO | | NULL | | | i_data | longtext | NO | | NULL | | | i_parentid | int(8) | NO | | NULL | | +--------------+--------------+------+-----+---------+----------------+

  • A question on getting number of nodes in a Binary Tree

    - by Robert
    Dear all, I have written up two functions (pseudo code) for calculation the number of nodes and the tree height of a Binary Tree,given the root of the tree. Most importantly,the Binary Tree is represented as the First chiled/next sibling format. so struct TreeNode { Object element; TreeNode *firstChild; TreeNode *nextSibling; } Calculate the # of nodes: public int countNode(TreeNode root) { int count=0; while(root!=null) { root= root.firstChild; count++; } return count; } public int countHeight(TreeNode root) { int height=0; while(root!=null) { root= root.nextSibling; height++; } return height; } This is one of the problem I saw on an algorithm book,and my solution above seems to have some problems,also I didn't quite get the points of using this First Child/right sibling representation of Binary Tree,could you guys give me some idea and feedback,please? Cheers!

  • Ruby getting the diagonal elements in a 2d Array

    - by Calm Storm
    Hi, I was trying some problems with my 2D ruby array and my LOC reduces a lot when I do array slicing. So for example, require "test/unit" class LibraryTest < Test::Unit::TestCase def test_box array = [[1,2,3,4],[3,4,5,6], [5,6,7,8], [2,3,4,5]] puts array[1][2..3] # 5, 6 puts array[1..2][1] # 5, 6, 7, 8 end end I want to know if there is a way to get a diagonal slice? Lets say I want to start at [0,0] and want a diagonal slice of 3. Then I would get elements from [0,0], [1,1], [2,2] and I will get an array like [1,4,7] for example above. Is there any magic one-liner ruby code that can achieve this? 3.times do {some magic stuff?}

  • different ways of getting the IP Address

    - by Sachindra
    I was actually going through the question 1636644 .. and got confused with this " The getenv() function access to any environment variable to get the related value! " Also .. " It would probably be better to use $_SERVER['REMOTE_ADDR']; to prevent incompatibilities between servers. " what kind of compatibility issue can this be ?? Lastly, it says $_SERVER is an array with many elements but I find only the IP Address there .. does this array store anything else too??? apologies for all these questions packed in one .. this is bcoz these are all related ..
