Member Function Documentation

◆ forceFirstHomePositionRequestFalse()

void WGEScene::forceFirstHomePositionRequestFalse ( )

Manually force all following requests not to be considered the first one.

Definition at line 42 of file WGEScene.cpp.

References firstHomePositionRequest.

◆ isHomePositionRequested()

bool WGEScene::isHomePositionRequested ( )

Indicates whether we want the widget showing the scene to be tranferred to its home position.

This is the case if we have the first child added to the scene.

Returns: true if reset to bbox is requested

private

Indicates whether we still have the first request for home position (isHomePositionRequested()).
