How to remove hover/clicked effect in pygtk?

Question

I want to remove or turn off this hover and clicked effect on button in pygtk. Do you have any ideas? I couldn't find anything useful here gtk.Button

I am talking about this:

Normal

Hover

Clicked

Answer 1

-Do you really want a button? The main distinction between buttons and labels are those effects (labels don't generate events, but you can make them do so by packing them into a Gtk.EventBox)

-Here's how to disable the events that cause the effects in first place:

import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk

class MainWindow(Gtk.Window):
    def __init__(self):
        super(MainWindow, self).__init__()
        self.connect("destroy", lambda x: Gtk.main_quit())
        self.set_size_request(400, 300)

        btn1 = Gtk.Button("One - inert button")
        btn2 = Gtk.Button("Two - active button")

        btn1.connect("enter-notify-event", self.on_leave)
        btn1.connect("button-press-event", self.on_leave)

        vbox = Gtk.VBox()
        vbox.pack_start(btn1, False, False, 0)
        vbox.pack_start(btn2, False, False, 0)

        self.add(vbox)
        self.show_all()

    def on_leave(self, btn, event):
        return True

    def run(self):
        Gtk.main()


def main(args):
    mainwdw = MainWindow()
    mainwdw.run()

    return 0

if __name__ == '__main__':
    import sys
    sys.exit(main(sys.argv))

The on_leave method's return True tells the default handler that events are handled so it won't do the effects. The top button One doesn't react, the bottom one still does.
