Member Function Documentation

◆ activeWindow()

QWidget* ccPickingHub::activeWindow ( ) const

inline

Returns the currently active window.

Definition at line 74 of file ecvPickingHub.h.

Referenced by RgbDialog::onItemPicked(), and ScalarDialog::onItemPicked().

◆ addListener()

bool ccPickingHub::addListener	(	ccPickingListener *	listener,
		bool	exclusive = `false`,
		bool	autoStartPicking = `true`,
		ecvDisplayTools::PICKING_MODE	mode = `ecvDisplayTools::POINT_OR_TRIANGLE_PICKING`
	)

Adds a listener.

Parameters

listener	listener to be registered
exclusive	prevents new listeners from registering
autoStartPicking	automatically enables the picking mode on the active window (if any)
mode	sets the picking mode (warning: may be rejected if another listener is currently registered with another mode)

Returns: success
