Member Function Documentation

virtual bool16 ViewListBoxTreeViewWidgetMgr::ApplyDataToWidget ( const NodeID &  node, IPanelControlData *  widgetList, int32  message = 0  ) const

protectedvirtual

Most TreeViews will override this method. This method is called from ApplyNodeIDToWidget() to apply the Node specific data to the widgets within the main node widget. Typically, the name of the node and icon for the node are applied to a Text widget and an icon widget. When overriding this method, the base class version is not typically called.

Parameters

node	the node whose data you want applied to the given widget
widgetList	This is the IPanelControlData of the Tree node widget. The Tree node widget typically contains subwidgets which are changed based on the specific data for the given node.
message	if you call an ITreeViewMgr method with a message, that message will be passed back to you in this parameter. For instance, if it is expensive to update the text, but not the icon. You could pass yourself a kMyIconChanged message in ITreeViewMgr::NodeChanged() and then only update the icon in ApplyDataToWidget() if message=kMyIconChanged

Returns

bool16 kTrue if you were successful in applying data, kFalse if unsuccessful. If kFalse is returned, the TreeViewMgr will ask you to create a new widget for this node with CreateWidgetForNode() and then ask to apply data again

Reimplemented from CTreeViewWidgetMgr.

virtual IControlView* ViewListBoxTreeViewWidgetMgr::CreateWidgetForNode ( const NodeID &  node ) const

protectedvirtual

Create the widget, but don't change the widget-data to match the node; that should be done in ApplyNodeIDToWidget

Parameters

node

Returns

reference to IControlView interface on newly created widget boss object

Reimplemented from CTreeViewWidgetMgr.

virtual PMReal ViewListBoxTreeViewWidgetMgr::GetNodeWidgetHeight ( const NodeID &  node ) const

virtual

Returns desired height in pixels of widget rendering given node.

Parameters

node
return	desired height in pixels of widget rendering given node

Reimplemented from CTreeViewWidgetMgr.

virtual PMReal ViewListBoxTreeViewWidgetMgr::GetNodeWidgetWidth ( const NodeID &  node ) const

virtual

Returns desired width in pixels of widget rendering given node.

Parameters

node

Returns

desired width in pixels of widget rendering given node

Reimplemented from CTreeViewWidgetMgr.

virtual void ViewListBoxTreeViewWidgetMgr::PreDeleteWidget ( IControlView *  widget )

virtual

Only TreeViews that need to do something prior to the tree deleting a widget will need to override this method. This method is called from the tree view manaager before it deletes a widget. For example, this provides the widget manager client to disconnect any child widgets it wants to continue to manage.

Reimplemented from CTreeViewWidgetMgr.

virtual void ViewListBoxTreeViewWidgetMgr::RegisterStyles ( )

protectedvirtual

This method is where you specify the widget that should be used for each of the Tree Styles you support. If you only support 1 Tree Style, then you need only Register one style in from this method. This method is automatically called when it is time to register your styles. Inside you should call RegisterStyleWidget() to asssociate a widget with a style.

If your tree can contain different widgets depending on the NodeID, then you should use override CreateWidgetForNode instead of this RegisterStyles() method

This default implementation registers the standard Tree widgets for large and small palette rows. If you aren't using the standard widgets, then override this and DON'T CALL the base class method.
