[Qt-interest] custom shaped buttons

[Carlos Smith]

Thanks,  maybe I am missing something,  but the problem I had is that I cannot find the corresponding palette entry for the pressed color I set in the style sheet.

I had debug code that dumped the RGB's for every color in the QPalette::ColorRole enumeration, like this:

                QStyleOptionButton opt;
                initStyleOption(&opt);
                QPalette palette = opt.palette;

                QBrush tempBrush;

                tempBrush = palette.color(QPalette::Active, QPalette::Window);
                qDebug() << "Window color" << tempBrush.color().red() << tempBrush.color().green() <<  tempBrush.color().blue();
                tempBrush = palette.color(QPalette::Active, QPalette::WindowText);
                qDebug() << "WindowText color" << tempBrush.color().red() << tempBrush.color().green() <<  tempBrush.color().blue();

And none of the colors was the one I had set for the "pressed" state.  Though the same stylesheet declaration worked for standard QPushbuttons.  If I recall I traced all the way down and they (Qt) had the color somehow, but I couldn't get it from the application level.

I would have expected the opt.palette to have been loaded with the colors corresponding to the current (pressed) state.  I know of no other palette to use.   For that matter, the bevel draws correctly with the "pressed" state background color, but I can't get the foreground/text/window color to use to draw my custom text.  Hence I use a custom property in the style sheet to get the functionality I want, which is a real kludge.

Thanks,
Carlos

I'm pretty sure you'll find it in the style option "state" field.
According to the docs for QStyle::State the QStyle::State_Sunken bit should be set.

http://developer.qt.nokia.com/doc/qt-4.8/qstyle.html#StateFlag-enum

if( opt.state & QStyle::State_Sunken )
     ... button is pressed ...

Ross.
