QtCreator is an IDE from Nokia for Qt. It contains QtDesigner for UI design. This article describes:
To create your C++ applications you can use any text editor. But life will be much easier if you gain QtCreator's features. That means
Here is a short example of how you can create a "hello world" application. For more information read the user documentation.
Then select New File or Project -> Qt C++ Project -> Qt Gui Application -> name = helloworld -> Next -> Next -> Finish
Select Edit -> Forms -> mainwindow.ui. Add the widgets you want by drag-and-drop:
Select the mainwindow. This is the one un-intuitive step. To lay out the objects in the mainwindow, you do not select the objects in the mainwindow, but the mainwindow itself.
Select Form -> Lay Out in a Grid
You get a decent look, and if you resize the window, the widgets resize as well.
To use KDE classes like KMessageBox, you need to tell QtCreator to use the KDE libraries when building. Go to your home directory, change into yourproject and modify yourproject.pro. Add the line
LIBS += -lkdeui
Then you can start using KDE classes in your code.
To add a toolbar, right-click on the UI and choose "Add Toolbar". Then you can set icons and text in your mainwindow's constructor with code like this:
This describes how to use QtCreator to integrate existing KDE 4 applications. It has been tested with QtCreator 1.2.80 and SUSE Linux 11.1 but should work same or similar with every combination. As an example KDE application we use ktimetracker from the kdepim module, other applications should work likewise.
You can either work with code on your disk or have QtCreator do the repository checkout.
|If the checkout fails with the message "remote host hung up unexpectedly" do a checkout from konsole. You may have to accept git.kde.org's fingerprint.|
/path/to/kdepim -DCMAKE_INSTALL_PREFIX=/usr/local -DLIB_SUFFIX=64 -DCMAKE_BUILD_TYPE=debugfull
DLIB_SUFFIX=64 means that you want to install your libraries into directories named lib64, not lib. /path/to/kdepim is where your source code is.
Projects -> Active run configuration=ktimetracker -> build settings -> build steps -> make -> show details -> activate ktimetracker.
