Cathed an error.
Fixed, and now it works
def apply_stylesheet_clicked(self, index):
        if self.w.cmb_stylesheet.currentText() == "As Loaded": return
        self.styleeditor.styleSheetCombo.setCurrentIndex(index)
        self.styleeditor.on_applyButton_clicked()     
Thank you so much!
    

Excellent!

Hello! How to register so that when choosing tab_mdi TabWidget interface went to mdi_mode. Thanks!

You can add a signal in designer to tab_widget that is sent when the tab changes.
currentChanged(int) pobably would do what you want.

I don't see the sender (tab_mdi) in the constructor.
self.w.main_tab_widget.setCurrentIndex(TAB_MDI)
            self.w.tab_mdi.setChecked(True)
ACTION.SET_MDI_MODE()
        self.w.mdi_mode_button.setChecked(True) I need to somehow link it in the handler. I think so.
