Hello Matplotlib Users !
The new ToolManager works well, it is very easy to add new ToolButtons !
See snapshot and associated code.
Questions:
···
- Can we use this with Tkinter ? If yes can you send or point me to one example ?
(I know how to use a NavigationToolbar2Tk() with tkinter, but not a ToolbarTk() )
- How do we attach a callback function to the new button ?
Thanks!
From the bottom of:
python - Ignore matplotlib cursor widget when toolbar widget selected? - Stack Overflow
This works well, and the Toggle Buttons remain Toggled, depressed.
