Cursor image

[Sergey Vdovin]

Hello. How to change the mouse cursor image when the pointer is over a Splitter widget? I want to change it to something like a picture from Windows standard theme to make the user know that it's a resizable zone. Thank you in advance.

You can use set_system_cursor() to set the cursor.

Thank you. Sorry for disturbing you, but could you please also suggest a way to implement hover behavior for a widget? I can't understand what module to use. I'm sure it's a common task. I must have overlooked something in Docs

Here are a few examples that should help you get this figured out:

Thank you very much. I would have never solved it by myself. Though, the task turned out to be a little bit trickier for Splitter widget. If apply the suggested code directly to Splitter (eg., sliding horizontally, sizable_from: 'right'), the cursor change it appearance not only when it is over the resizable zone but also over the whole zone from the left side of the screen to the resizable stripe. The following adjustment works well:  # Check whether the mouse position is in the Splitter        

if (self.width - self.strip_size) < pos[0] and self.width > pos[0]: # instead of if "self.collide_point(*pos):" in this article https://programmer.help/blogs/implementation-of-hover-event-in-kivy-control.html

    Clock.schedule_once(self.mouse_enter_css, 0)

else:

    Clock.schedule_once(self.mouse_leave_css, 0)
