Interactive cursor details
2+
~~~~~~~~~~~~~~~~~~~~~~~~~~
3+
4+
Setting a mouse cursor on a window has been moved from the toolbar to the
5+
canvas. Consequently, several implementation details on toolbars and within
6+
backends have been removed.
7+
8+
``NavigationToolbar2.set_cursor`` and ``backend_tools.SetCursorBase.set_cursor``
9+
................................................................................
10+
11+
Instead, use the `.FigureCanvasBase.set_cursor` method on the canvas (available
12+
as the ``canvas`` attribute on the toolbar or the Figure.)
13+
14+
``backend_tools.SetCursorBase`` and subclasses
15+
..............................................
16+
17+
``backend_tools.SetCursorBase`` was subclassed to provide backend-specific
18+
implementations of ``set_cursor``. As that is now removed, the subclassing
19+
is no longer necessary. Consequently, the following subclasses are also
20+
removed:
21+
22+
- ``matplotlib.backends.backend_gtk3.SetCursorGTK3``
23+
- ``matplotlib.backends.backend_qt5.SetCursorQt``
24+
- ``matplotlib.backends._backend_tk.SetCursorTk``
25+
- ``matplotlib.backends.backend_wx.SetCursorWx``
26+
27+
Instead, use the `.backend_tools.ToolSetCursor` class.
28+
29+
``cursord`` in GTK and wx backends
30+
.......................................
31+
32+
The ``backend_gtk3.cursord`` and ``backend_wx.cursord`` dictionaries are
33+
removed. This makes the GTK module importable on headless environments.
