How to restore a default size of the created buttons(custom plugin of Qt Designer) on the form? Rebuild ui file with default parameters of widgets.

  • I have created a custom plugin for Qt Designer it simply QPushButton class with corrected size of button that creates(modified default values of the size), but if i have a many forms with this buttons(with different size each button) and i need to restore their size to default (wich previously was generated in ui file when the button is created) it is possible? If possible then how? I could provide any information if needed.

  • The size of a QPushButton is driven by the layout you place it in, the minimum/maximum size constraints it has, and its size policies. The closest thing that a button has to a 'default' size is the value computed and returned by sizeHint(), which is driven by the button text, icon etc.
