  • Making a window a desktop in XLib/Qt

    - by TomMan
    I am trying to write a simple program to act as my desktop background in Qt, I have made it all work fine apart from making it a Desktop Widget. I have no idea on how to do this, I don't mind using XLib or Qt for doing this, but if anyone has some suggestions I would be very happy.

  • Qt QListView - context menus?

    - by QLatvia
    I'm trying to add a context (right click) menu to a Qt QListView. I see in Qt 3.3 there is "contextMenuRequested" (which I could use) - http://doc.trolltech.com/3.3/qlistview.html#contextMenuRequested. However, I can't see such a method in Qt4. Does anyone know how to add a context menu to a QListView?

  • Compatibility between Qt and Boost sockets libraries

    - by cake
    Hello In my work, I'm developing a Viewer client for a Offshore simulation server, using sockets to send the simulation data from the Simulator to de Viewer. But, the server uses Boost.asio as it's sockets library. As the client uses Qt for it's GUI, I was wondering if there is any problem in using de Qt Networking library for handling the sockets. Is there any compatibility issues? Thanks in advance, and sorry for my bad english.

    - by Eye of Hell
    Hello. Qt library includes advanced meta-programming capabilities using they own preprocessing moc compiler. Does anyone knows, is it possible to create some kind of mix-ins via it? For example, i have a QString and want to add a method to it without sub-classing and changing existing code. Does Qt have such solutions for that?

  • MultiOS "Jet Database" for C++/Qt?

    - by Airjoe
    Hopefully I can articulate this well: I'm porting an application I made years ago from VB6 (I know, I know!) to C++/Qt. In my original application, one thing I liked was that I didn't need an actual SQL server running, I could just use MS Access .mdb files. I was wondering if something similar exists for Qt that will work on multiple OSes - a database stored in a file, pretty much, but that I can still run SQL queries with. Not sure if something like this exists or not, but any help appreciated, thanks!

  • Qt C++ XML, validating against a DTD?

    - by Airjoe
    Is there a way to validate an XML file against a DTD with Qt's XML handling? I've tried googling around but can't seem to get a straight answer. If Qt doesn't include support for validating an XML file, what might be the process of implementing validation myself? Any good reference to start with in regards to validating XML against a spec? Thanks for the help!

    - by Narek
    I want to use a field (kind of QTextEdit), which is capabale of storing picture and text (like MS Word is doing) and it serializes and deserialaizes picture+text data. Is there any Qt Widget that allows us to manipulate with picture and text simultaniously and it has set/get functions which operate with serializable type? In othger words, I want to know if there exsists any Qt widget that can store picture+text and has "get" types of function that returns the content of that widgets editable area, which is a Type that could be serialized with QDataStream.

  • Taking screenshot of a specific window - C++ / Qt

    - by Switch
    In Qt, how do I take a screenshot of a specific window (i.e. suppose I had Notepad up and I wanted to take a screenshot of the window titled "Untitled - Notepad")? In their screenshot example code, they show how to take a screenshot of the entire desktop: originalPixmap = QPixmap::grabWindow(QApplication::desktop()->winId()); How would I get the winId() for a specific window (assuming I knew the window's title) in Qt? Thanks

    - by Dave
    What is the correct type to use in Qt development (or C++ in general) for decimal arithmetic, i.e. the equivalent of System.Decimal struct in .Net? Does Qt provide a built-in struct? (I can't find it in the docs, but maybe don't know where to look.) Is there a "standard" C++ library to use?
