| mxLayoutManager | |
| Events | |
| mxEvent. | Fires between begin- and endUpdate after all cells have been layouted in layoutCells. |
| Functions | |
| mxLayoutManager | Constructs a new automatic layout for the given graph. |
| Variables | |
| graph | Reference to the enclosing mxGraph. |
| bubbling | Specifies if the layout should bubble along the cell hierarchy. |
| enabled | Specifies if event handling is enabled. |
| undoHandler | Holds the function that handles the endUpdate event. |
| moveHandler | Holds the function that handles the move event. |
| resizeHandler | Holds the function that handles the resize event. |
| Functions | |
| isEnabled | Returns true if events are handled. |
| setEnabled | Enables or disables event handling. |
| isBubbling | Returns true if a layout should bubble, that is, if the parent layout should be executed whenever a cell layout (layout of the children of a cell) has been executed. |
| setBubbling | Sets bubbling. |
| getGraph | Returns the graph that this layout operates on. |
| setGraph | Sets the graph that the layouts operate on. |
| hasLayout | Returns true if the given cell has a layout. |
| getLayout | Returns the layout for the given cell and eventName. |
| beforeUndo | Called from undoHandler. |
| cellsMoved | Called from moveHandler. |
| cellsResized | Called from resizeHandler. |
| getCellsForChanges | Returns the cells for which a layout should be executed. |
| getCellsForChange | Executes all layouts which have been scheduled during the changes. |
| addCellsWithLayout | Adds all ancestors of the given cell that have a layout. |
| addAncestorsWithLayout | Adds all ancestors of the given cell that have a layout. |
| addDescendantsWithLayout | Adds all descendants of the given cell that have a layout. |
| executeLayoutForCells | Executes all layouts for the given cells in two phases: In the first phase layouts for child cells are executed before layouts for parent cells with mxEvent.BEGIN_UPDATE, in the second phase layouts for parent cells are executed before layouts for child cells with mxEvent.END_UPDATE. |
| layoutCells | Executes all layouts which have been scheduled during the changes. |
| executeLayout | Executes the given layout on the given parent. |
| destroy | Removes all handlers from the graph and deletes the reference to it. |
Fires between begin- and endUpdate after all cells have been layouted in layoutCells. The <code>cells</code> property contains all cells that have been passed to layoutCells.
mxLayoutManager.prototype.graph
Reference to the enclosing mxGraph.
mxLayoutManager.prototype.isEnabled = function()
Returns true if events are handled. This implementation returns enabled.
mxLayoutManager.prototype.setEnabled = function( enabled )
Enables or disables event handling. This implementation updates enabled.
| enabled | Boolean that specifies the new enabled state. |
mxLayoutManager.prototype.isBubbling = function()
Returns true if a layout should bubble, that is, if the parent layout should be executed whenever a cell layout (layout of the children of a cell) has been executed. This implementation returns bubbling.
mxLayoutManager.prototype.setBubbling = function( value )
Sets bubbling.
mxLayoutManager.prototype.hasLayout = function( cell )
Returns true if the given cell has a layout. This implementation invokes getLayout with mxEvent.LAYOUT_CELLS as the eventName. Override this if creating layouts in getLayout is expensive and return true if getLayout will return a layout for the given cell for mxEvent.BEGIN_UPDATE or mxEvent.END_UPDATE.
mxLayoutManager.prototype.getLayout = function( cell, eventName )
Returns the layout for the given cell and eventName. Possible event names are mxEvent.MOVE_CELLS and mxEvent.RESIZE_CELLS when cells are moved or resized and mxEvent.BEGIN_UPDATE or mxEvent.END_UPDATE for the bottom up and top down phases after changes to the graph model. mxEvent.LAYOUT_CELLS is used to check if a layout exists for the given cell. This is called from hasLayout.
mxLayoutManager.prototype.beforeUndo = function( undoableEdit )
Called from undoHandler.
| cell | Array of mxCells that have been moved. |
| evt | Mouse event that represents the mousedown. |
mxLayoutManager.prototype.cellsMoved = function( cells, evt )
Called from moveHandler.
| cell | Array of mxCells that have been moved. |
| evt | Mouse event that represents the mousedown. |
mxLayoutManager.prototype.cellsResized = function( cells, bounds, prev )
Called from resizeHandler.
| cell | Array of mxCells that have been resized. |
| bounds | mxRectangle taht represents the new bounds. |
mxLayoutManager.prototype.executeLayoutForCells = function( cells )
Executes all layouts for the given cells in two phases: In the first phase layouts for child cells are executed before layouts for parent cells with mxEvent.BEGIN_UPDATE, in the second phase layouts for parent cells are executed before layouts for child cells with mxEvent.END_UPDATE.
mxLayoutManager.prototype.destroy = function()
Removes all handlers from the graph and deletes the reference to it.
Executes all layouts which have been scheduled during the changes.
mxLayoutManager.prototype.layoutCells = function( cells, bubble )
Constructs a new automatic layout for the given graph.
function mxLayoutManager( graph )
Reference to the enclosing mxGraph.
mxLayoutManager.prototype.graph

mxLayoutManager.prototype.moveHandler
Holds the function that handles the resize event.
mxLayoutManager.prototype.resizeHandler
Returns true if events are handled.
mxLayoutManager.prototype.isEnabled = function()
Enables or disables event handling.
mxLayoutManager.prototype.setEnabled = function( enabled )
Returns true if a layout should bubble, that is, if the parent layout should be executed whenever a cell layout (layout of the children of a cell) has been executed.
mxLayoutManager.prototype.isBubbling = function()
Sets bubbling.
mxLayoutManager.prototype.setBubbling = function( value )
Returns the graph that this layout operates on.
