ResizeNodesMode

ResizeNodesMode(/*GraphCanvas*/ canvas, /*GraphSelection*/ selection)

This is an input mode for resizing selected nodes.

Parameters:

canvas - the canvas for which to handle user input

selection - the selection to use (note that this is a reference and thus a "live" object)

activate

activate()

activates this instance.

The selection instance passed to this input mode at creation time is checked for the current set of selected nodes. If there are no selected nodes, then this input mode deactivates itself. Otherwise the selected nodes are indicated by resizable ghost objects. It is assumed that the left mouse button is pressed. While the user moves the mouse the ghosts are resized accordingly indicating the potential new sizes of the selected nodes. If the user releases the left mouse button, the ghosts become invisible, and the real selected nodes get their new sizes. The mouse moves the corner or side (as specified by the mode) of the ghost for the main node. This corresponds to a delta in the width and height of the main node which is applied to the ghosts for the other selected nodes.

deactivate

deactivate()

deactivates this instance. If necessary ghost objects are hidden.
