Hello
I'm currently working on a program which read 16bit(565) BMP files.
I've tried hard to read them with pyQt and show them directly but it never worked properly, the image were not read properly even with the good format as argument.
So I've decided to call a wx App to show them but the problem I have now occurs when I launch a new wx App, the Qt window get stuck and the lineEdit are not updated as long as I don't press a button into the Qt window.
I'd like to find a way to update the lineEdit field even when a wx App pop out.
An other problem occurs when I close the Qt window before the wx window, python is still running after closing both window in this order... Don't know why...
For the reading of the files, I've used a part of the code from Scru which help me to quickly write this little program. Thank you Scru.
There is three file in my program:
