Represents a X11 GUI control that displays a View.
Members of this class should only be accessed from the GUI thread. Exceptions to this rule are noted on the documentation page for each individual member.
The Thread Access Verifier will enforce this rule when it is active.
More details about thread safety and the main thread of the application can be found in Threading model, GUI.
class X11MapControl : public MapControlA Carmenta Engine MapControl is used to integrate a map view into the GUI of an application. Carmenta Engine provides several different MapControl classes, for different API:s and GUI platforms; for a complete list see MapControl classes in Carmenta Engine.
This control uses the X11 library to integrate Carmenta Engine into an X11 application.
The default behavior of the MapControl (X11) is to re-throw exceptions that occur when it calls into the Carmenta Engine kernel. You can provide a handler for the IMapControl::error event if you want to suppress this behavior, for example if you want to send the errors to an application log or display a custom error dialog.
