问题 Problem I want to create multiple buttons and bind them to a function. The problem is that whenever I click on one button, the function is called multiple times. It seems to be a problem with the event connection. When I look at the instance that called the function when I pressed a button, it seems that the function gets called from every button at once?!

问题 im writing a paint app in Kivy (Python) and i orientated myself at the Kivy Paint Tutorial.

I added a Scatter, so everything that is drawn is inside the scatter and it is posible to move it all together.

问题 I'm using the TabbedPanel (with the default tab_pos: "top_left" ) but the headers (as one can see in the docs) are slighty not on the left.
