Member Function Documentation

void PlaneOverviewCameraTool::Activate ( )

virtual

Switch on a tool.

Inherited classes also register events they want to respond to with the PreviewToolHelper. As events are lost when the tool is deactivated without notification to the PreviewTool, things from the last activation can be cleaned up here too.

Implements Tool.

void PlaneOverviewCameraTool::KeypressEvent	(	int	keycode,
		int	modifiers,
		bool	pressed
	)

virtual

Notify of a Keypress event.

Currently unused as the preview cannot get keyboard input focus.

void PlaneOverviewCameraTool::MouseButtonEvent ( wxMouseEvent & e )

virtual

Notify of a mouse button press on the panorama preview.

Parameters

e	The event created by wxWidgets.

void PlaneOverviewCameraTool::MouseMoveEvent	(	double	x,
		double	y,
		wxMouseEvent &	e
	)

virtual

Notify when the mouse pointer has moved over the panorama preview.

The coordinates are in the space of the panorama output at full size, with no output cropping.

Parameters

x	The horizontal position of the mouse pointer in panorama pixels.
y	The vertical position of the mouse pointer in panorama pixels.
e	The event created by wxWidgets.

Reimplemented from Tool.
