Hello Everyone, I am currently experimenting a little with Genode 14.08. When playing around in Qt5, I encountered some problems when trying to change the geometry of a QMainWindow. I have an additional Genode::Thread running, which can trigger a geometry-change of the application's main window by methods provided by the MainWindow.
When a change of the window's geometry is triggered, it seems as if the window-decorations are properly resized, but the QtWindow underneath is kept at its original size. Additionally, the thread which triggers the geometry-change is blocked (this holds true for the Genode::Thread, as well as for a QThread). Resizing the window with the mouse works properly. I took a look at the Nitpicker Qt-Plugin, where I noticed two things: 1. - There is some unused code in qnitpickerplatformwindow.cpp in QNitpickerPlatformWindow::handle_events(). Until now I did not dig into the Window_slave_policy, but the inactive code segment looks to me, as if it should change the QtWindow's geometry. 2. - The Processing seems to stop somewhere before returning the framebuffer of the the PlatformWindow when detaching / attaching it from / to the rm_ssession. Since I'm not quite familiar with all the internal Nitpicker / Qt stuff, it would be great if anyone with a little more experience could provide some help. ;-) - Or am I even trying something which is not intended?
