hi all
so i think i managed to set up everything to create and push an event, but
i'm not quite there yet
in SongEditor.cpp i have added some lines that should draw a .png (using
drawPixmap) based on the bNext flag
I added some debug, did lots of tests and it looks like this part of the
code is executed when i expect it to, but the gui does not update at that
same moment :-(
i have the feeling that the actual gui update is done somewhere else, but i
cant figure out how that happens
all help is welcome !
grtz
