PointerButton


Unit:SDL_geoatlas
Class:TGeoAtlas
Declaration:property PointerButton: TSpeedButton;

The PointerButton property allows to access and manipulate the pointer button of the atlas. All properties and methods of a standard Delphi speed button are available (see the Delphi manual for details).

When the PointerButton is down, you can drag the current map by using the mouse (if the map is larger than the map window of TGeoAtlas). The drag mode is indicated by a hand cursor.

Hint: Please note that the PointerButton and the ZoomButton must not be down simultaneously, since this will result in unpredictable behavior of TGeoAtlas.

Example: This property is used in the following example program (see http://www.lohninger.com/examples.html for downloading the code): atlas
