QToolButton with text: Overwrite minimal height to minic regular button height

阅读更多关于 QToolButton with text: Overwrite minimal height to minic regular button height

问题 I am displaying QToolButtons with icon plus text ( Qt::ToolButtonTextBesideIcon ) outside of a tool bar. Each button has a QAction associated with it which determines the used icon and the displayed text. All those buttons are placed inside a QGridLayout. So far so good.
