Porting Qt Application from Windows to Linux

[jpn]

What about

splitter->setStyleSheet("background: red");

splitter->setStyleSheet("background: red");

To copy to clipboard, switch view to plain text mode 

or

QPalette p = splitter->palette();
p.setColor(QPalette::Window, Qt::red);
splitter->setPalette(p);
splitter->setAutoFillBackground(true);

QPalette p = splitter->palette();
p.setColor(QPalette::Window, Qt::red);
splitter->setPalette(p);
splitter->setAutoFillBackground(true);

To copy to clipboard, switch view to plain text mode 

?
