WPF Toolkit ZoomControl
can be used to toggle mouse wheel zooming using Ctrl modifier or without it.
can be used to enable absolute (center-oriented) zooming by mousewheel. Relative zooming is used by default.
Nice zoom-in animation after new graph generation can be achieved by using this code:
tg_zoomctrl.Zoom = 0.01; //disable zoom control auto fill animation by setting this value
tg_zoomctrl.ZoomToFill();//manually update zoom control to fill the area
Xceed Zoombox control
Added new property FreeDragEnabled
to allow free layout dragging (not panning as it not allows to interact with objects but dragging allows) operation on an empty space (like ZoomControl works by default)
New Zoombox property AreaSelectionBrush
allows to set the color of the selection area.
New Zoombox property SelectionModifiers
makes possible to select the area like the ZoomToSelectionModifiers but with the final result of
event call. With this feature you can get the selection Rect
as the event param and use it for ex. for the multiple vertices selection. You can find an example in the showcase app at the Dynamic Graph page.
