Re: [PyQt] Delete a Laytou
I think it's best if you provide a stripped piece of code of what you've achieved so far and let the list take a look at it..

You can add multiple widgets, each having their own layout, to it and set it as the central widget of your mainwindow. There's no need for deleting a layout and set a new one, since you alternate between the added widgets / layouts.

[PyQt] isSystemTrayAvailable() causes segfault
Hi. I am trying to use QtGui.QSystemTrayIcon.isSystemTrayAvailable(), but every time I run the methon I get a segfault. I'm using python 2.6.4 with pyqt 4.7.0.

Re: [PyQt] isSystemTrayAvailable() causes segfault
I just updated to python 2.6.5 and still no luck. My Qt version is also 4.6.2. Later I'll try to run it with the latest development snapshots of pyqt and update the thread.

[PyQt] Help - WINAPI PSoundW and WINAPI Beep linker error using sip
I am not sure what do I need to do to include the windows library into sip, so it links correctly. I am trying to use PlaySoundW and Beep which are defined in MMSystem.h in a class called PSound.

Re: [PyQt] Help - WINAPI PSoundW and WINAPI Beep linker error using sip
I found out I need to include winmm.lib, but I can't figure out how to force sip to include this. I tried adding /LIBPATH:C:\Program Files\Microsoft SDKs\Windows\v6.0A\Lib and including winmm.lib under LIBS of the makefile, but I still get the same linker errors.
