How to change Qcombobox popup width

[advseo32]

[quote author="raven-worx" date="1375899990"]this->view() returns an QAbstractItemView which is derived from QWidget. QWidget has a method named setMinimumWidth() ....
what Qt version do you use?![/quote]

Sure, QWidget has a member function setMinimumWidth(),

my problem is inside setMinimumWidth(),

this->view()->sizeHintForColumn(0) ( QWidget hasn't a methode sizeHintForColumn(0)

[raven-worx]

no...but QAbstractItemView does!
Since you implicitly cast the view instance to a QWidget it's clear that the compiler complains about it!

change the line
@
QWidget *view = this->view() ;
@
to
@
QAbstractItemView *view = this->view() ;

This works perfect, Thank you very much.

[quote author="raven-worx" date="1375879559"]you can subclass QComboBox and reimplement showPopup() method if you need the size content dependent. Something like this:
@
void MyComboBox::showPopup()
{
this->view()->setMinimumWidth(this->view()->sizeHintForColumn(0));
QComboBox::showPopup();
}
