Public Member Functions

abstract HPS.SceneTreeItem AddChild (HPS.Key in_key, HPS.SceneTree.ItemType in_type, string in_title)
 This function is used to create a new SceneTreeItem to be the child of this SceneTreeItem. This function will be invoked if this SceneTreeItem has children and Expand has been invoked on it. This function should contain any necessary calls to GUI toolkits to create the appropriate GUI elements, e.g., see the implementations in the mfc_sandbox or wpf_sandbox. Additionally, since this function requires the creation of a derived SceneTreeItem, that derived SceneTreeItem should use the base constructor which takes the same arguments this function. More...

virtual void Select ()
 This function will be invoked when this SceneTreeItem should be marked as selected. Marking an item as selected means that the key backing this SceneTreeItem has been highlighted with the options specified in the associated SceneTree or is along a path in which a highlight has occurred. This highlighting may have come as a result of the Highlight function on a SceneTreeItem being invoked (not necessarily this SceneTreeItem), or potentially due to the HighlightOperator or HighlightAreaOperator highlighting the key backing this SceneTreeItem or highlighting some path which includes the key backing this SceneTreeItem. This function is meant to be overridden to allow one to change the appearance of a selected SceneTreeItem, e.g., by bolding the text or changing an icon, to signify this new state. If this function is overridden, the overriding function should invoke this base function. More...
 
void Unhighlight (ulong in_highlight_options_index)
 This function will remove the highlight with the options specified in the associated SceneTree from this SceneTreeItem. This can cause elements along the path to this item (and this item itself) to be marked as unselected unless those items lie along a path which is still highlighted. Depending on the type of the SceneTreeItem, sometimes an unhighlight is nonsensical. In this case, no unhighlight will be performed. More...
 
void Unhighlight ()

If the options requested is not part of the associated SceneTree highlight options, it will be added to them. More...
 
virtual void Unselect ()
 This function will be invoked when this SceneTreeItem should be marked as unselected. Marking an item as unselected means that the key backing this SceneTreeItem is no longer highlighted with the options specified in the associated SceneTree or is no longer along a path in which a highlight has occurred. This unhighlighting may have come as a result of the Unhighlight function on a SceneTreeItem being invoked (not necessarily this SceneTreeItem), or potentially due to the HighlightOperator or HighlightAreaOperator unhighlighting the key backing this SceneTreeItem. or unhighlighting some path which includes the key backing this SceneTreeItem. This function is meant to be overridden to allow one to change the appearance of a selected SceneTreeItem, e.g., by no longer bolding the text or changing an icon, to signify this new state.

Detailed Description

The SceneTreeItem class is a smart pointer which corresponds to an item or node in a tree object in a GUI toolkit, e.g., a TreeViewItem in WPF or an HTREEITEM in MFC. This class must be derived from to facilitate tree creation in the various GUI toolkits. It is used to represent items in a scene graph or segment browser.

inlinevirtual

This function returns the type the object, as declared. This does not necessarily give the true type of the underlying object.

Returns
    The declared type of the object in question, which may differ from the true, underlying type.

Reimplemented from HPS.Object.

void HPS.SceneTreeItem.ReExpand ( )
inline

Collapses this SceneTreeItem and then re-expands the tree. It will try to preserve the original expansion state, however, if the underlying scene structure has changed, the resulting expansion may look different.

virtual void HPS.SceneTreeItem.Select ( )
inlinevirtual

This function will be invoked when this SceneTreeItem should be marked as selected. Marking an item as selected means that the key backing this SceneTreeItem has been highlighted with the options specified in the associated SceneTree or is along a path in which a highlight has occurred. This highlighting may have come as a result of the Highlight function on a SceneTreeItem being invoked (not necessarily this SceneTreeItem), or potentially due to the HighlightOperator or HighlightAreaOperator highlighting the key backing this SceneTreeItem or highlighting some path which includes the key backing this SceneTreeItem. This function is meant to be overridden to allow one to change the appearance of a selected SceneTreeItem, e.g., by bolding the text or changing an icon, to signify this new state. If this function is overridden, the overriding function should invoke this base function.

void HPS.SceneTreeItem.Unhighlight ( ulong  in_highlight_options_index)
inline

This function will remove the highlight with the options specified in the associated SceneTree from this SceneTreeItem. This can cause elements along the path to this item (and this item itself) to be marked as unselected unless those items lie along a path which is still highlighted. Depending on the type of the SceneTreeItem, sometimes an unhighlight is nonsensical. In this case, no unhighlight will be performed.

Unselect

void HPS.SceneTreeItem.Unhighlight ( )
inline

This function will remove the highlight with the options specified in the associated SceneTree from this SceneTreeItem. This can cause elements along the path to this item (and this item itself) to be marked as unselected unless those items lie along a path which is still highlighted. Depending on the type of the SceneTreeItem, sometimes an unhighlight is nonsensical. In this case, no unhighlight will be performed.

Unselect

void HPS.SceneTreeItem.Unhighlight ( HPS.HighlightOptionsKit  in_highlight_options)
inline

This function will remove the highlight with the options specified in the associated SceneTree from this SceneTreeItem. This can cause elements along the path to this item (and this item itself) to be marked as unselected unless those items lie along a path which is still highlighted. Depending on the type of the SceneTreeItem, sometimes an unhighlight is nonsensical. In this case, no unhighlight will be performed. If the options requested is not part of the associated SceneTree highlight options, it will be added to them.

Unselect

virtual void HPS.SceneTreeItem.Unselect ( )
inlinevirtual

This function will be invoked when this SceneTreeItem should be marked as unselected. Marking an item as unselected means that the key backing this SceneTreeItem is no longer highlighted with the options specified in the associated SceneTree or is no longer along a path in which a highlight has occurred. This unhighlighting may have come as a result of the Unhighlight function on a SceneTreeItem being invoked (not necessarily this SceneTreeItem), or potentially due to the HighlightOperator or HighlightAreaOperator unhighlighting the key backing this SceneTreeItem. or unhighlighting some path which includes the key backing this SceneTreeItem. This function is meant to be overridden to allow one to change the appearance of a selected SceneTreeItem, e.g., by no longer bolding the text or changing an icon, to signify this new state. If this function is overridden, the overriding function should invoke this base function.
