Hi everyone.
I have a little issue with layouts. It seems to be simple thing but I didn'=
t find a solution yet.
I am loading PyQt4 interfaces using the "standard way" (from .ui with loadU=
i method OR from .py with setupUi method). However custom widgets (derived =
from QWieget, QLabel etc.) don't appear on the screen unless I put them ins=
ide a QLayout objetc. Other qt basic widgets display normally.
Also when I read their size it is always different from what I set, and the=
ir x,y coordinates are always turned to zero. It seems that the custom widg=
et loose the main window reference. I explictly set the main window as thei=
r parent but the problem remains.
Putting custom widgets inside layout may not seem to be hard, but it is bor=
ing to work like this in large interfaces. Iam building a simple app to loa=
d interfaces made by users, so I would like the users not to have this need=
.
Thank you for any help!
