Why sethome() function doesn't work.I'm searching this for hours please help me

@nareba2780 said in Set Home Page In Browser:

sethome_btn.triggered.connect(self.sethome())

Look at the slot specification of all your other connect statements, e.g.

self.tabs.currentChanged.connect(self.current_tab_changed)
back_btn.triggered.connect(lambda: self.tabs.currentWidget().back())

Can you see the difference? Either specify a method name without the () or use a lambda: ... and you can call a method with ().
