Event handler for resizing cells. This handler is automatically created in mxGraph.createHandler.
| mxVertexHandler | Event handler for resizing cells. |
| Functions | |
| mxVertexHandler | Constructs an event handler that allows to resize vertices and groups. |
| Variables | |
| cursor | Specifies the cursor to be used for this handle. |
| image | Specifies the mxImage to be used to render the handle. |
| image | Specifies the mxImage to be used to render the handle. |
| Functions | |
| getPosition | Hook for subclassers to return the current position of the handle. |
| setPosition | Hooks for subclassers to update the style in the state. |
| execute | Hook for subclassers to execute the handle. |
| copyStyle | Sets the cell style with the given name to the corresponding value in state. |
| processEvent | Processes the given mxMouseEvent and invokes setPosition. |
| positionChanged | Called after setPosition has been called in processEvent. |
| getRotation | Returns the rotation defined in the style of the cell. |
| getTotalRotation | Returns the rotation from the style and the rotation from the direction of the cell. |
| init | Creates and initializes the shapes required for this handle. |
| createShape | Creates and returns the shape for this handle. |
| initShape | Initializes <shape> and sets its cursor. |
| redraw | Renders the shape for this handle. |
| isHtmlRequired | Returns true if this handle should be rendered in HTML. |
| rotatePoint | Rotates the point by the given angle. |
| flipPoint | Flips the given point vertically and/or horizontally. |
| snapPoint | Snaps the given point to the grid if ignore is false. |
| setVisible | Shows or hides this handle. |
| reset | Resets the state of this handle by setting its visibility to true. |
| destroy | Destroys this handle. |
Constructs an event handler that allows to resize vertices and groups.
| state | mxCellState of the cell to be resized. |
mxHandle.prototype.image
Specifies the mxImage to be used to render the handle. Default is null.
Specifies the mxImage to be used to render the handle. Default is null.
mxHandle.prototype.setPosition = function( bounds, pt, me )
Hooks for subclassers to update the style in the state.
mxHandle.prototype.copyStyle = function( key )
