Size of icons in QToolBar

  • Hi,

    I amtrying to increase the size of icons in a QToolBar, but with no success. The images are showing in the buttons at (i think) 16x16. This is the code:

    class ViewSelector(QtGui.QToolBar):
    def init(self, parent):
    super(ViewSelector, self).init(parent)
    self.setIconSize(QtCore.QSize(32, 32))
    self.buttongroup = QtGui.QButtonGroup(self)
    self.buttons = [QtGui.QPushButton(QtGui.QPixmap('config/icons/a.png'), None),
    QtGui.QPushButton(QtGui.QPixmap('config/icons/b.png'), None),
    QtGui.QPushButton(QtGui.QPixmap('config/icons/c.png'), None)]
    for index in range(len(self.buttons)):
    button = self.buttons[index]
    button.index = index
    button.setMaximumSize(32, 32)
    button.setMinimumSize(32, 32)

    def selectview(self):


    The source images are 64x64. Is it possible to change the size of the icons (the method sitIconSize would indicate so)? If so, what am i missing?

    Cheers, Lars

  • In my C++ code this works:
    buttons = new QToolBar( this );
    buttons->setIconSize( QSize( 32, 32 ) );
    buttons->setToolButtonStyle( Qt::ToolButtonTextUnderIcon ); // you should set Qt::ToolButtonIconOnly

    Maybe QToolBar is on widget which has fixed size with height under 32 px?
