You just need to set the environment variable QT_PLUGIN_PATH.
The Qt SDK include the tools needed to build desktop or embedded applications.
The latest version can be grabbed from the Qt-Company homepage. The author personally prefers the online installer package as it allows you to install and update several Qt releases. The SDK itself has a maintenance tool which will allow you to update the SDK to the latest version.
the "Open file" or "Save as" dialogs), because by default Qt tries to use the native GTK File Diag, but the invocation assumes the use of X11 and would segfault in Wayland. If you do not want to -- or cannot -- allow such execution privileges, a workaround is to set the following as appropriate in your environment variables: then you are most likely using a Qt5 platform theme or style plugin which has not been recompiled against the latest version of Qt5.
This issue can be worked around in two ways: If pure Qt4 (non-KDE) applications do not stick with your selected Qt4 style, then you'll probably need to tell Qt4 how to find KDE's styles (Oxygen, Phase etc.). These usually use Qt private headers which means they depend on an exact version of Qt and not just a matching soname.
A console application does not provide any graphical user interface and will normally be called as part of a system service or from the command line.

Some of its more important features include: The Qt framework is emerging as a major development platform and is the basis of the KDE software community, among other important open source and proprietary applications such as VLC, Virtual Box, Mathematica and many others. The file is rather difficult to navigate because it contains a lot of information not related to appearance, but for any changes you can just add to the end of the file and overwrite any previous values (make sure to add your modification under the [Qt] header).
One way to solve this is to fake the running desktop environment by setting Qt supports most platforms that are available today, even some of the more obscure ones, with more ports appearing every once in a while. It is highly recommended to install NDK version 10e because of some known issues. You can install it from AUR as described bellow or build it yourself, you can find build instructions on QT wiki page.
