Implements the selection model for a graph. Here is a listener that handles all removed selection cells.
graph.getSelectionModel().addListener(mxEvent.CHANGE, function(sender, evt)
{
var cells = evt.getProperty('added');
for (var i = 0; i < cells.length; i++)
{
// Handle cells[i]...
}
});| mxGraphSelectionModel | Implements the selection model for a graph. |
| Events | |
| mxEvent.UNDO | Fires after the selection was changed in changeSelection. |
| mxEvent. | Fires after the selection changes by executing an mxSelectionChange. |
| Functions | |
| mxGraphSelectionModel | Constructs a new graph selection model for the given mxGraph. |
| Variables | |
| doneResource | Specifies the resource key for the status message after a long operation. |
| updatingSelectionResource | Specifies the resource key for the status message while the selection is being updated. |
| graph | Reference to the enclosing mxGraph. |
| singleSelection | Specifies if only one selected item at a time is allowed. |
| Functions | |
| isSingleSelection | Returns singleSelection as a boolean. |
| setSingleSelection | Sets the singleSelection flag. |
| isSelected | Returns true if the given mxCell is selected. |
| isEmpty | Returns true if no cells are currently selected. |
| clear | Clears the selection and fires a <change> event if the selection was not empty. |
| setCell | Selects the specified mxCell using setCells. |
| setCells | Selects the given array of mxCells and fires a <change> event. |
| getFirstSelectableCell | Returns the first selectable cell in the given array of cells. |
| addCell | Adds the given mxCell to the selection and fires a <select> event. |
| addCells | Adds the given array of mxCells to the selection and fires a <select> event. |
| removeCell | Removes the specified mxCell from the selection and fires a <select> event for the remaining cells. |
| removeCells | |
| changeSelection | Inner callback to add the specified mxCell to the selection. |
| cellAdded | Inner callback to add the specified mxCell to the selection. |
| cellRemoved | Inner callback to remove the specified mxCell from the selection. |
| mxSelectionChange | Action to change the current root in a view. |
| Functions | |
| mxCurrentRootChange | Constructs a change of the current root in the given view. |
| execute | Changes the current root of the view. |
Fires after the selection was changed in changeSelection. The <code>edit</code> property contains the mxUndoableEdit which contains the mxSelectionChange.
Fires after the selection changes by executing an mxSelectionChange. The <code>added</code> and <code>removed</code> properties contain arrays of cells that have been added to or removed from the selection, respectively. The names are inverted due to historic reasons. This cannot be changed.
