QComboBox palette not working

Note that the platform is allowed to ignore values of the palette so it might be what is happening.

Definitely not. Since i mentioned at the beginning that palette of textColors are applied to my ComboBoxes, so that is not igrnoring.

Hi
Some platforms QStyle might not use ( as in ignore) some of the roles.
Some roles that worked on linux had no effect in Windows in my app.
http://doc.qt.io/qt-5/style-reference.html

Also, the Qcombobox is actually a view and uses the models role hints which
might not use palette that much for "items"

@mrjj Frankly i changed all to styleSheets, not such handy, more complex code but working more or less...

@Engelard
ok :)
Im not sure what you want to color, but stylesheet works fine as long
one not trying to combine with models roles :)

Im not sure what you want to color,

simple BG-color, with palette it would be 2 lines of code, with stylesheet it 6(alot of conversons to each color from QCOlor, then it convert to string, lots of extrawork).

You can also do
ui->comboBox->setItemData( 0, QColor( Qt::black ), Qt::BackgroundRole );
ui->comboBox->setItemData( 1, QColor( Qt::red ), Qt::BackgroundRole );
since its uses an (internal) model. and is basically a view like Listview etc.

Hey, that's pretty good!

But it applied only for items inside(which great, will use in future maybe), i still can't find something like ->setData(); so it would be applied for comboBox container it'self.

@Engelard
well the roles in the model is only use for items and not for the view

but it tried your code and it did work for me ??

Hi

QPalette oriPal;  //at the .h file
oriPal = cbBox->palette();
oriPal.setColor(QPalette::Base, Qt::red);
cbBox->setPalette(oriPal);

did color it red as picture showed.
so it did use QPalette::Base ( Qt 5.11, windows)
