 This doesn't happen automatically, actually. Typically you'd use
wxEVT_UPDATE_UI handler to do it: as it will be called for both the menu
item and the toolbar tool (because they have the same ID), it would set
their states to the same value.

 I.e. this is the expected behaviour if you do nothing else.

 You should be able to put a breakpoint on wxToolBarToolBase::Toggle() to
check where is it called from for the first tool.
