Method Detail

_applyIcon

public void _applyIcon(java.lang.String value,
                       java.lang.String old)

Applies changes of the property value of the property iconSelected.

For further details take a look at the property definition: _applyIcon(java.lang.String, java.lang.String).

_applyLabel

public void _applyLabel(java.lang.Object value,
                        java.lang.Object old)

_applyParent

public java.lang.Object _applyParent(java.lang.Object value,
                                     java.lang.Object old)

Overrides:

_applyParent in class Widget

_applySelected

public void _applySelected(java.lang.Object value,
                           java.lang.Object old)

_evalCurrentIcon

public java.lang.Object _evalCurrentIcon()

_getRowStructure

public void _getRowStructure(java.lang.Object labelOrTreeRowStructure,
                             java.lang.String icon,
                             java.lang.String iconSelected)

The tree constructor understands two signatures. One compatible with the original qooxdoo tree and one compatible with the treefullcontrol widget. If the first parameter if of type TreeRowStructure the tree element is rendered using this structure. Otherwhise the all three arguments are evaluated.

This function evaluates the constructor arguments and returns a TreeRowStructure for the tree element.

_handleDisplayableCustom

public void _handleDisplayableCustom(java.lang.Object vDisplayable,
                                     java.lang.Object vParent,
                                     java.lang.Object vHint)

Overrides:

_handleDisplayableCustom in class Parent

_onmousedown

public void _onmousedown(Event e)

_onmouseup

public void _onmouseup(java.lang.Object e)

addToCustomQueues

public void addToCustomQueues(java.lang.Object vHint)

Adds the current item to a custom queue.

addToTreeQueue

public void addToTreeQueue()

Adds the current element to the tree queue.

destroy

public void destroy()

deselects, disconnects, removes and disposes the current tree element and its content.

destroys the current item (TreeFile or TreeFolder) and all its subitems. The destruction of the subitems is done by calling destroyContent. This is done if the subitem has the method destroyContent which is true if the subitem is a TreeFolder (or one of its subclasses).

The method destroyContent is defined in the TreeFolder class.

getLabel

public java.lang.String getLabel()

Returns the (computed) value of the property label.

For further details take a look at the property definition: label.
