Here’s a snippet for Kivy, which adds functionality to get the widget at a given screen position. It’s probably not the most refined approach in the world but until we can get a proper mouse over event, this seems to work for now.
To use it, simply add it to your App class like:
class TestApp(WidgetPosition, App):
...
and call get_widget_at(pos)
And here’s the code:
class WidgetPosition:
def get_widget_at(self, pos, node=None):
x, y = pos
if not node:
node = self.root
for widget in node.children:
if self._is_over_widget(widget, x, y):
return self.get_widget_at(pos, widget)
if node == self.root and not self._is_over_widget(node, x, y):
return None
return node
def _is_over_widget(self, widget, x, y):
if x >= widget.pos[0] and x <= widget.pos[0] + widget.width and \
y >= widget.pos[1] and y <= widget.pos[1] + widget.height:
return True
return False
