XUL:Tree

Editable Tree

The following properties and methods are added for editable tree support. To enable editing of a tree, set the editable attribute on the <tree> to true.

For content trees, the editable attribute may be set to false on a specific <treecell> to disable editing of that cell.

RDF Built trees do not currently support editing.

Editable trees do not work in Firefox 2, they work in Firefox 3 though.

Properties

editingRow

The integer row index of the cell currently being edited, or -1 if no cell is being edited.

Methods

stopEditing ( shouldAccept )
