I added a FloatButton on my screen, but I am unable to associate any on_release actions to it. I suspect the issue is linked to the fact that my FloatButton actually inherits from FloatLayout, so it does not have the on_release property?Here is my FloatButton definition in the kv file:
<FloatButton@FloatLayout>: id: float_add_button # Giving id to button size_hint: (None, None) text: '' btn_size: (70, 70) size: (70, 70) bg_color: (0.404, 0.227, 0.718, 1.0) # pos_hint: {'x': .6} Button: text: float_add_button.text markup: True font_size: 40 size_hint: (None, None) size: float_add_button.btn_size pos_hint: {'x': .5, 'y': .8} background_normal: '' background_color: (0, 0, 0, 0) canvas.before: Color: rgba: (0.404, 0.227, 0.718, 1.0) Ellipse: size: self.size pos: self.posand further down the kv file I assing on_release
<MainWindow>: name: 'main' RelativeLayout: orientation: 'lr-tb' size_hint: 1, 1 padding: '20sp' canvas.before: Rectangle: pos: self.pos size: self.size # A few buttons here # # # FloatButton: id: addButton text: '+' markup: True background_color: 1, 0, 1, 0 pos_hint: {"x":.5,"top":.5} on_release: print("[TEST] on_release works!")However, I get the following error:
