In my current layout, scrollview is not detecting the mouse's scroll-wheel scrolling in either direction to navigate it's text upwards or downwards. You are able to click and drag with either mouse button or click and drag with the mouse's scroll-wheel.
Click prints:
MyMap Down
MyBubble Down
MyBox Down
MyBoxes_Box Down
MyBoxes_Box2 Down
MyScroll2 Down
MyGrid2 Down
MyLabel2 Down
Click and Drag prints:
MyMap Down
MyBubble Down
MyBox Down
MyBoxes_Box Down
MyBoxes_Box2 Down
MyScroll2 Down
If you only use the mouse wheel in scrollview above the mapview, prints:
MyMap Down
<kivy.core.window.window_sdl2.WindowSDL object at 0x000002A4C1302458>
Layering of Kivy App, shows RelativeLayout:
MyMap Down
<kivy.core.window.window_sdl2.WindowSDL object at 0x000001E26AA42458>
MyBubble Down
<kivy.uix.relativelayout.RelativeLayout object at 0x000001E278CE2458>
MyBox Down
<kivy.uix.bubble.BubbleContent object at 0x000001E278D51C10>
MyBoxes_Box Down
<__main__.MyBox object at 0x000001E278D51C78>
MyBoxes_Box1 Down
<__main__.MyBoxes_Box object at 0x000001E278D51CE0>
MyScroll1 Down
<__main__.MyBoxes_Box1 object at 0x000001E278D51D48>
MyGrid1 Down
<__main__.MyScroll1 object at 0x000001E278D51E18>
MyLabel1 Down
<__main__.MyGrid1 object at 0x000001E278D8B1E8>
I have added an on_touch_down event to help show that kivy is detecting the touch inside the scrollview widget but also detecting all parent widgets as well, I think it has something to do with the RelativeLayout but I've tried a bunch of stuff in the documentation and am stuck. If you plug and play my example, you can click the scrollview/label and then click and drag the scrollview/label to see the different events occuring based on mouse/click behavior. I have also added a walk() command to show that once the bubble is added, a RelativeLayout is created for all it's children widgets which I believe is where the touch.is_mouse_scrolling= 'scrollup'/'scrolldown' motion event is being absorbed by the MapView.
If anyone can help me solve this issue I would greatly appreciate it!
