◆ RegisterKeyActionCallback()

void cloudViewer::visualization::VisualizerWithKeyCallback::RegisterKeyActionCallback	(	int	key,

	)

Register callback function with access to GLFW key actions.

Parameters

key	GLFW key value, see GLFW key values.
callback	The callback function. The callback function takes `Visualizer *`, `action` and `mods` as input and returns a boolean indicating UpdateGeometry() needs to be run. The `action` can be one of GLFW_RELEASE (0), GLFW_PRESS (1) or GLFW_REPEAT (2), see GLFW input interface. The `mods` specifies the modifier key, see GLFW modifier key.

◆ RegisterMouseButtonCallback()

void cloudViewer::visualization::VisualizerWithKeyCallback::RegisterMouseButtonCallback ( std::function< bool(Visualizer *, int, int, int)> callback )

Register callback function with access to GLFW mouse actions.

Parameters

callback The callback function. The callback function takes Visualizer *, button, action and mods as input and returns a boolean indicating UpdateGeometry() needs to be run. The action can be one of GLFW_RELEASE (0), GLFW_PRESS (1) or GLFW_REPEAT (2), see GLFW input interface. The mods specifies the modifier key, see GLFW modifier key.

◆ RegisterMouseMoveCallback()

void cloudViewer::visualization::VisualizerWithKeyCallback::RegisterMouseMoveCallback ( std::function< bool(Visualizer *, double, double)> callback )

Register callback function with access to GLFW mouse actions.

Parameters

callback The callback function. The callback function takes Visualizer *, and the x and y mouse position inside the window and returns a boolean indicating if UpdateGeometry() needs to be run. See GLFW mouse position for more details.

◆ RegisterMouseScrollCallback()

void cloudViewer::visualization::VisualizerWithKeyCallback::RegisterMouseScrollCallback ( std::function< bool(Visualizer *, double, double)> callback )

Register callback function with access to GLFW mouse actions.

Parameters

callback The callback function. The callback function takes Visualizer *, and the x and y scroll values and returns a boolean indicating if UpdateGeometry() needs to be run. A normal mouse only provides a y scroll value. See GLFW mouse scrolling for more details.
