Ext.AbstractPluginExt.tree.ViewDDPlugin
This plugin provides drag and/or drop functionality for a TreeView.
- - -It creates a specialized instance of DragZone which knows how to drag out of a TreeView -and loads the data object which is passed to a cooperating DragZone's methods with the following properties:
copy property, or true if the TreeView was configured
- with allowCopy: true and the control key was pressed when the drag operation was begun.It also creates a specialized instance of Ext.dd.DropZone which cooperates with other DropZones which are members of the same -ddGroup which processes such data objects.
- - -Adding this plugin to a view means that two new events may be fired from the client TreeView, beforedrop and
-drop
True if drops on the tree container (outside of a specific tree node) are allowed (defaults to false)
-True if drops on the tree container (outside of a specific tree node) are allowed (defaults to false)
-Allow inserting a dragged node between an expanded parent node and its first child that will become a -sibling of the parent when dropped (defaults to false)
-True if the tree should only allow append drops (use for trees which are sorted, defaults to false)
-True if the tree should only allow append drops (use for trees which are sorted, defaults to false)
-A named drag drop group to which this object belongs. If a group is specified, then both the DragZones and DropZone -used by this plugin will only interact with other drag drop objects in the same group (defaults to 'TreeDD').
-The ddGroup to which the DragZone will belong.
- - -This defines which other DropZones the DragZone will interact with. Drag/DropZones only interact with other Drag/DropZones -which are members of the same ddGroup.
- -The ddGroup to which the DropZone will belong.
- - -This defines which other DragZones the DropZone will interact with. Drag/DropZones only interact with other Drag/DropZones -which are members of the same ddGroup.
- -Defaults to true
Set to false to disallow dragging items from the View
Defaults to true
Set to false to disallow dragging items from the View
Defaults to true
Set to false to disallow the View from accepting drop gestures
Defaults to true
Set to false to disallow the View from accepting drop gestures
The delay in milliseconds to wait before expanding a target tree node while dragging a droppable node -over the target (defaults to 1000)
-The color to use when visually highlighting the dragged -or dropped node (defaults to 'c3daf9' - light blue). The color must be a 6 digit hex value, without -a preceding '#'. See also nodeHighlightOnDrop and nodeHighlightOnRepair.
-Whether or not to highlight any nodes after they are
-successfully dropped on their target. Defaults to the value of Ext.enableFx.
-See also nodeHighlightColor and nodeHighlightOnRepair.
Whether or not to highlight any nodes after they are
-repaired from an unsuccessful drag/drop. Defaults to the value of Ext.enableFx.
-See also nodeHighlightColor and nodeHighlightOnDrop.
The destroy method is invoked by the owning Component at the time the Component is being destroyed. -Use this method to clean up an resources.
-Disable the plugin and set the disabled flag to true.
-Disable the plugin and set the disabled flag to true.
-This event is fired through the TreeView. Add listeners to the TreeView object
- - -Fired when a drop gesture has been triggered by a mouseup event in a valid drop position in the TreeView. - -
The TreeView node if any over which the mouse was positioned.
- -Returning false to this event signals that the drop gesture was invalid, and if the drag proxy
-will animate back to the point from which the drag began.
Returning 0 To this event signals that the data transfer operation should not take place, but
-that the gesture was valid, and that the repair operation should not take place.
Any other return value continues with the data transfer operation.
- -The data object gathered at mousedown time by the cooperating DragZone's -getDragData method it contains the following properties:
copy property, or true if the TreeView was configured
- with allowCopy: true and the control key was pressed when the drag operation was begunThe Model over which the drop gesture took place.
-"before", "after" or "append" depending on whether the mouse is above or below the midline of the node,
-or the node is a branch node which accepts new child nodes.
A function to call to complete the data transfer operation and either move or copy Model instances from the source -View's Store to the destination View's Store.
- - -This is useful when you want to perform some kind of asynchronous processing before confirming -the drop, such as an confirm call, or an Ajax request.
- - -Return 0 from this event handler, and call the dropFunction at any time to perform the data transfer.
This event is fired through the TreeView. Add listeners to the TreeView object -Fired when a drop operation has been completed and the data has been moved or copied.
-The TreeView node if any over which the mouse was positioned.
