Abstract base class for all map tools.
Map tools are user interactive tools for manipulating the
map canvas. For example map pan and zoom features are
implemented as map tools.

%Docstring
Use this to associate a QAction to this maptool. Then when the setMapTool
method of mapcanvas is called the action state will be set to on.
Usually this will cause e.g. a toolbutton to appear pressed in and
the previously used toolbutton to pop out. *

Returns associated action with map tool or NULL if no action is associated

Returns if the current map tool active on the map canvas

Use this to associate a button to this maptool. It has the same meaning
as setAction() function except it works with a button instead of an QAction. *

%Docstring
Returns associated button with map tool or NULL if no button is associated

Sets a user defined cursor

Emit map tool changed with the old tool

Gets search radius in mm. Used by identify, tip etc.
The values is currently set in identify tool options (move somewhere else?)
and defaults to Qgis.DEFAULT_SEARCH_RADIUS_MM.

Gets search radius in map units for given context. Used by identify, tip etc.
The values is calculated from searchRadiusMM().
