[SOLVED] How to get QComboBox arrow width?

[RazrFalcon]

I mean this:

Is it possible?
I want to add QToolButton just before this arrow.

[giesbert]

getting this size can be achieved by the style, where also QComboBox itself reads it from.

I'm misunderstood. Can you give a code example?
Thanks.

See http://doc.qt.nokia.com/4.7/style-reference.html#combo-box

Still can't understand :(

You need something like:

subclass QCombobox, use "QStyle::subControlRect":http://doc.qt.nokia.com/4.7/qstyle.html#subControlRect

@
MyCombo::foo()
{
QStylre* pStyle = style();
QComboBoxStyleOption opt;
opt.initFrom(this);
QRect rc = pStyle->subControlRect(QStyle::CC_ComboBox, opt, QStyle::SC_ComboBoxArrow, this);
}
@

Code just written in the forum, not tested

But take, care, then you overlay the text field.

Thanks a lot!

This works for me:
@QStyle *pStyle = style();
QStyleOptionComboBox opt;
opt.initFrom(this);
QRect rc = pStyle->subControlRect(QStyle::CC_ComboBox, &opt, QStyle::SC_ComboBoxArrow, this);
qDebug()<<rc.width();@
