  • Changing the color of a QTextBlock that is within a QTextDocument

    - by yan bellavance
    Is there any other way to change the QTextLayout of a QTextBlock that is within a QTextDocument without having to subclass QAbstractTextDocumentLayout and call its documentChanged? I know that on a call to QTextBlock::layout() const ; the returned QTextLayout object can only be modified from the documentChanged implementation of a QAbstractTextDocumentLayout subclass but I was wodering if there was any other way before I implemented it.

  • c#: what is the purpose of wpf vs. winforms [closed]

    - by every_answer_gets_a_point
    i know wpf can be richer-looking, but what is the point of using them if they complicate things so much? for example if i want to do something on form load in wpf i have to through the trouble of writing this: public MyWindow() { Loaded += MyWindow_Loaded; } private void MyWindow_Loaded(object sender, RoutedEventArgs e) { // do work here } whereas in winforms all i do is double click on the form the question is what are the benefits of using wpf over winforms?

  • Objective C IBOutlets

    - by Alan
    In cases where multiple buttons call an IBOutlet, can the IBOutlet determine which button was pressed? edit: All fixed and wired up. key point: Object ID is not sender tag!

  • How do I track the method the user is looking at in VS 2010 IDE as an Addin

    - by Rob
    I have been wandering around the object model for VS 2010 and haven't been able to work out the best method for watching what the user is looking at in the main edit window. I know that each Class/method/property is broken down into its own . What I would ideally like is to hook to an event which says "The user has moved the cursor onto Project.Class.Method" and ideally "and is looking at line 4". Any suggestions?

  • How do I cause the controller buttons to display for an Apple Quicktime video embedded in Firefox?

    - by Doug Treadwell
    I am trying to embed a Quicktime video in Firefox, but when I do the controller buttons do not appear. I've tried both the old style embed tag and the new style object tags, but when I set the "controller" option to true there is no change in the appearance of the plugin. The video loads, but it is zoomed in on some portion of the video and there are no buttons to play, pause, etc.

    - by eli
    In a Flex / Java app stack using remoting (via BlazeDS), classes to hold data passed back and forth between client and server need to be maintained in both the client (in ActionScript) and server (in Java). I want a way to maintain theses classes in Java only, and have the corresponding ActionScript value object classes generated by the build process.

It keeps warning me that: Memory Fragmentation may be causing .NET to reserver too much free memory. or Memory Fragmentation is affecting the size of the largest object that can be allocated Because I have OCD, this problem must be resolved. What are some standard coding practices that help avoid memory fragmentation. Can you defragment it through some .NET methods? Would it even help?

  • GitHub Api: How to get Root :tree_sha of a repository?

    - by Chris Jacob
    How do I get the Root :tree_sha of a GitHub repository via the GitHub API? The GitHib API help pages don't seem to explain this critical piece of information: http://develop.github.com/p/object.html Can get the contents of a tree by tree SHA tree/show/:user/:repo/:tree_sha To get a listing of the root tree for the facebox project from our commit listing, we can call this: $ curl http://github.com/api/v2/yaml/tree/show/defunkt/facebox/a47803c9ba26213ff194f042ab686a7749b17476

  • Using .net Datetime in sql query

    - by Patrick
    I have a DateTime object I want to compare against an sql datetime field in a where clause. I'm currently using: "where (convert( dateTime, '" & datetimeVariable.ToString & "',103) <= DatetimeField)" But I believe datetimeVariable.ToString will return a different value depending on the culture where the system is running. How would you handle this so it is culture independent?

  • Best Way to Include Debug Code?

    - by stormin986
    I am programming Android applications, and the best way here may or may not be the same as Java in general. I simply want to be able to set a debug flag that will only execute certain portions of code when it's set to true––equiv to C++ setting a preprocessor #define DEBUG and using #ifdef DEBUG. Is there an accepted or best way to accomplish this in Java? Right now I'm just going to set a variable in my Application object, but I don't imagine this is the best way.

  • Calling a function in an iframe from a parent in firefox

    - by wyatt
    I'm trying to call a function, test(), of an iframe from the parent document using the code subframe.test(); subframe refers correctly to the iframe, alert(subframe) returns [object HTMLIFrameElement], and the function runs in both IE7 and opera (9.23), but not firefox (3.0), chrome (3.0) or safari (3.03 beta windows). I assume these browsers support the functionality, so wondering if perhaps I'm using an incorrect call which IE and Opera support anyway, which wouldn't surprise me.
