Detailed Description

The GameRoot widget is a reduced Desktop widget. It does work with any widgets not only windows and does not provide a processEvent function like Desktop does. The GameRoot forwards processEvent messages to the activated widget. This way a Game can easily provide a menu using a transparent Desktop widget with a SceneRenderer below. The Desktop and SceneRenderer can process the events send in the best suited way (a Desktop would maintain an absolute mouse whereas a SceneRenderer can use the relative mouse events directly).

Member Function Documentation

◆ dispose()

void Dragengine.Gui.GameRoot.dispose ( )

Disposes of the widget. This cleans all references and prepars the widget for beeing freed. If the widget is already disposed nothing happens.

Reimplemented from Dragengine.Gui.Widget.

◆ getActiveWidget()

Widget Dragengine.Gui.GameRoot.getActiveWidget ( )

Active widget if any.

◆ new()

GameRoot Dragengine.Gui.GameRoot.new ( )

Create GameRoot. GameRoot is located at (0,0) covering the entire screen.

Reimplemented from Dragengine.Gui.Panel.

◆ processEvent()

void Dragengine.Gui.GameRoot.processEvent ( Event event )

Process an event. This allows the widget to be used as the root widget in a game. Using this function you can implement your own desktop management routines or use no windows at all. An event is send to the root widget using this function. No other widget has to get an event sent through this function. Use the sendEvent function to further dispatch events through all widgets.
The default implementation is to send the event to yourself. Overwrite this behaviour to implement Desktop Widgets.
