Hi everyone,
I'm developing a Linux Qt (4.7.4) GUI application which can be shown/hidden using specific commands on a TCP socket. The base class is a QWidget, which then contains different labels, buttons, images, etc. There are more or less 30 elements.
My problem is that every time I call >show ()< on my main widget a black background immediately appears, but all the widgets and the real background (from a PNG image) comes after a certain delay (at least 0,5s on my desktop here). This every time I do a hide/show cycle.
How can I get rid of this delay? Or, at least, can I have all my interface coming out altogether, even if delayed, without the black "intermediate" background?
Thanks
Roberto
