Member Enumeration Documentation

enum ZqZoom::ZoomMode

Mode of zooming.

Enumerator
ZoomRubberRect	Press left button and drag mouse to select rectangular area to zoom. Release left button for the action and click right button to avoid action. Clicking right button allows to undo zoom.
ZoomInClick	Click left button to get closer view and right button for opposite action. Mouse position is used as center of scaling.
ZoomOutClick	Click left button to get more distant view and right button for opposite action. Mouse position is used as center of scaling.
ZoomRubberRect	Press left button and drag mouse to select rectangular area to zoom. Release left button for the action and click right button to avoid action. Clicking right button allows to undo zoom.

		double	nxy[2] = `NULL`
	)

virtual

Action of zooming in (or out, depending given scale factor) objects with natural group(s) by preset scale factor. Given natural coordinates are used as center of zooming. If NULL is passed instead of coordinates then current center of natural group coordinates is used.
