[solved]Set QCombobox:selected color to match Linux desktop "Theme".

[CraigH]

In order to make the qcombobox which currently has focus more identifiable (especially on small screens), I want to change the sytle for the "selected" state. The code below does that, but specifies a hard coded color. If I leave out the color style, the border is "black", not the normal "highlight". How do I tell Qt to use the normal "highlight" color which it retrieves from the desktop theme.

@QApplication A(argc, argv);
A.setStyleSheet("QComboBox:selected{ border-width:2px; border-style:solid; border-color:blue}");

Hi,

You can retrieve the color using the palette of the application and put it in your style sheet string

Thanks for the help. I always thought of the palette and style sheet as being completely separate, and would never have thought of your method. Here is the code I ended up using.

@QApplication A(argc, argv);
A.setStyleSheet(QString("QComboBox:selected{ border-width:2px;"
"border-style:solid; border-color:rgb(%1, %2, %3);}")
.arg(A.palette().highlight().color().red())
.arg(A.palette().highlight().color().green())
.arg(A.palette().highlight().color().blue()));

You're welcome !

IIRC, you can even simplify the code using the string notation #XXXXXX of the color (what QColor does when converted to a QString).

If this solves you're problem, please update the thread title prepending [solved] so other forum users may know a solution has been found :)

Found the function you were talking about. It makes for much cleaner code. Thanks again.

@QApplication A(argc, argv);
A.setStyleSheet(QString("QComboBox:selected { border-width:2px; "
"border-style:solid; border-color:%1;}")
.arg(A.palette().highlight().color().name()));
