问题 I would like to detect if user has clicked the 'maximize' button: In tkInter of course, but I don't know how. I have tried searching through StackOverflow, The Web & tkInter documents(mostly effbot's tkinterbook), but have not found anything related to what I am trying to get. 回答1: There is a good way to does it using .bind() , so let's get started! As we know, we can maximize the window using the command .state('zoomed') . root.state('zoomed') And we can get whatever window event by .bind("

问题 I am displaying the camera video in Kivy, but I can't find a way to record the video, I tried to use OpenCV Videowriter but because of the updating ( Clock.schedule_interval(self.update, 1.0/33.0)) it is constantly overwriting so the video that it saved is one image, does anybody have an alternative way. 回答1: Please look into the below code which may serve your purpose.

问题 The soft keyboard moves a TextView object up with it, (adjusting), and this causes the TextView to overlay another TextView that I'd like to be able to see. I need a way to lock this TextView specifically , so that the keyboard will overlay it. But only that component. I do not want to pan the entire window, just this one, single, TextView object. Is there a way to tell the TextView, "Dammit bro, don't move with the keyboard" programmatically? To be honest, I'd also be willing to settle for

The form's KeyPreview property is be set to True to let the form react to key presses before any other components.
