[Interest] About Qt StyleSheet

[Berkay Elbir]

Hi,

Actually, I think that problem is not related to any styles. If I write
this:

ui.newGroupNameLabel->setStyleSheet(" ");  also it does not have to be
QLabel. If I use QLineEdit, same problem occurs. Scenario is like that

If I call this code piece in constructor than everything is fine and you
can call setStyleSheet() function later there will be no problem. But If I
call this later for example slot of some button whatever, It occurs. It is
very strange, it affects whole widget after initialization.

Also, I know that If I use QPalette, problem does not occur but this is not
an option.


Cheers,

Berkay
