Minimize PyQt5 app with a button click

Question

i found some material on how to minimize a pyqt widget to system tray, but i did not manage to find what i need.

I would like to minimize a widget on a button click, i do not want to overwrite default close button, when person clicks window border close, it will still close, but when it clicks my button, it will minimize to system tray.

Is this even possible, since all examples try to overwrite default event. This code i am attaching was created in qtDesigner and it holds just one button,sort of like playground, i hope someone could help, Cheers.

Qt Designer creates a class that is used to fill another widget, it is not a widget, so it is recommended to create a class that inherits from the appropriate widget and fills in using the Ui_Form class. For more information read the following:

• http://pyqt.sourceforge.net/Docs/PyQt5/designer.html

Going to the point, you must use the showMinimized() method.
