Detailed Description

The ComponentTreeItem 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 component or model browser.

Constructor & Destructor Documentation

◆ ComponentTreeItem() [1/4]

HPS.ComponentTreeItem.ComponentTreeItem ( )
inline

The default constructor creates an uninitialized ComponentTreeItem object. The Type() function will return Type.None.

◆ ComponentTreeItem() [2/4]

HPS.ComponentTreeItem.ComponentTreeItem ( HPS.ComponentTreeItem  in_that)
inline

The copy constructor creates a ComponentTreeItem object that shares the underlying smart-pointer of the source ComponentTreeItem.

Parameters
in_thatThe source ComponentTreeItem to copy.

◆ ComponentTreeItem() [3/4]

HPS.ComponentTreeItem.ComponentTreeItem ( HPS.ComponentTree  in_tree,
HPS.CADModel  in_cad_model 
)
inline

This constructor creates a ComponentTreeItem suitable for acting as a root in a ComponentTree. The CADModel provided to this constructor should be accessible from the Canvas and layer associated with the ComponentTree, otherwise an exception will be thrown.

HPS.ComponentTreeItem.ComponentTreeItem ( HPS.ComponentTree  in_tree,
HPS.Component  in_component,
HPS.ComponentTree.ItemType  in_type 
)
inline

This constructor creates a ComponentTreeItem which is not suitable for acting as a root in a ComponentTree, but is suitable to be a ComponentTreeItem under the root of the ComponentTree. This constructor should be the one invoked in the overridden AddChild function.

Parameters
in_treeThe ComponentTree with which to associate this new ComponentTreeItem.
in_componentThe Component for this ComponentTreeItem. This value should come from the corresponding argument to AddChild.
in_typeThe type of this ComponentTreeItem. This value should come from the corresponding argument to AddChild.

Member Function Documentation

◆ AddChild()

abstract HPS.ComponentTreeItem HPS.ComponentTreeItem.AddChild ( HPS.Component  in_component,
HPS.ComponentTree.ItemType  in_type 
)
pure virtual

This function is used to create a new ComponentTreeItem to be the child of this ComponentTreeItem. This function will be invoked if this ComponentTreeItem 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. Additionally, since this function requires the creation of a derived ComponentTreeItem, that derived ComponentTreeItem should use the base constructor which takes the same arguments this function.

Parameters
in_componentThe Component for this ComponentTreeItem. Should be passed to as the corresponding argument to the base constructor.
in_typeThe type for this ComponentTreeItem. Should be passed to as the corresponding argument to the base constructor.
Returns
A newly created object derived from ComponentTreeItem.

◆ Assign()

virtual void HPS.ComponentTreeItem.Assign ( HPS.ComponentTreeItem  in_that)
inlinevirtual

Share the underlying smart-pointer of the ComponentTreeItem source.

Parameters
in_thatThe ComponentTreeItem source of the assignment.
Returns
A reference to this ComponentTreeItem.

◆ Collapse()

virtual void HPS.ComponentTreeItem.Collapse ( )
inlinevirtual

This function should be invoked when this ComponentTreeItem needs to collapse. If this function is overridden, the overriding function should invoke this base function. Additionally, this function will always release all children for this ComponentTreeItem when invoked.

◆ Equals()

bool HPS.ComponentTreeItem.Equals ( HPS.ComponentTreeItem  in_that)
inline

Check if the source ComponentTreeItem points to the same underlying impl as this ComponentTreeItem.

Parameters
in_thatThe source ComponentTreeItem to compare to this ComponentTreeItem.
Returns
true if the objects reference the same impl, false otherwise.

◆ Expand()

virtual void HPS.ComponentTreeItem.Expand ( )
inlinevirtual

This function should be invoked when this ComponentTreeItem needs to expand. If this function is overridden, the overriding function should invoke this base function. Additionally, this function will always repopulate the children for this ComponentTreeItem when invoked.

◆ GetComponent()

HPS.Component HPS.ComponentTreeItem.GetComponent ( )
inline

Gets the Component for this ComponentTreeItem. The type of the Component depends on the ComponentTree.ItemType for this ComponentTreeItem.

Returns
The Component for this ComponentTreeItem.

◆ GetItemType()

HPS.ComponentTree.ItemType HPS.ComponentTreeItem.GetItemType ( )
inline

Gets the item type for this ComponentTreeItem. This is used to determine what type of data this ComponentTreeItem represents in the ComponentTree.

Returns
The item type for this ComponentTreeItem.

◆ GetPath()

HPS.ComponentPath HPS.ComponentTreeItem.GetPath ( )
inline

Gets the ComponentPath corresponding to this ComponentTreeItem.

Returns
The ComponentPath corresponding to this ComponentTreeItem.

◆ GetTitle()

string HPS.ComponentTreeItem.GetTitle ( )
inline

Gets the title for this ComponentTreeItem. This is the text that should be displayed for this ComponentTreeItem in the ComponentTree.

Returns
The title for this ComponentTreeItem.

◆ GetTree()

HPS.ComponentTree HPS.ComponentTreeItem.GetTree ( )
inline

Gets the ComponentTree associated with this ComponentTreeItem. This provides a means of accessing the derived ComponentTree by this ComponentTreeItem if necessary.

Returns
The ComponentTree associated with this ComponentTreeItem.

◆ HasChildren()

bool HPS.ComponentTreeItem.HasChildren ( )
inline

Indicates whether this ComponentTreeItem has any children.

Returns
Whether this ComponentTreeItem has any children.

◆ Hide()

void HPS.ComponentTreeItem.Hide ( )
inline

This function will cause this ComponentTreeItem to be hidden if it isn't already. This will cause this item to be marked as hidden if it isn't already. Depending on the type of the ComponentTreeItem, sometimes a hide is nonsensical. In this case, no hide will be performed. If activated, this forces the visibility of the associated ComponentPath and all components under this path to invisible. Any visibility changes made previously at or below this path are flushed. When performing a highlight in combination with this function the highlight must be applied with Drawing.Overlay.InPlace to display properly. See this section for limitations and details on managing component visibility.

See also
OnHighlight

◆ Highlight() [3/3]

void HPS.ComponentTreeItem.Highlight ( HPS.HighlightOptionsKit  in_highlight_options)
inline

This function will cause this ComponentTreeItem to be highlighted with the options specified. If the options requested is not part of the associated ComponentTree highlight options, it will be added to them. This will cause this item to be marked as highlighted if it isn't already. Depending on the type of the ComponentTreeItem, sometimes a highlight is nonsensical. In this case, no highlight will be performed.

Parameters
in_highlight_optionsThe highlight options used during highlighting

OnHighlight

◆ IsExpanded()

bool HPS.ComponentTreeItem.IsExpanded ( )
inline

Indicates whether this ComponentTreeItem is currently expanded.

Returns
Whether this ComponentTreeItem is currently expanded.

◆ IsHidden()

bool HPS.ComponentTreeItem.IsHidden ( )
inline

Indicates whether this ComponentTreeItem is currently hidden. This may mean that the Hide function on this ComponentTreeItem was invoked, or that the Component backing this ComponentTreeItem was hidden via ComponentPath.Hide or ComponentPath.Isolate.

Note
The state of this ComponentTreeItem may not yet mirror the state of the underlying ComponentPath as the notification is asynchronous. In order for this ComponentTreeItem to mirror the state of the underlying ComponentPath, a synchronous update needs to be performed on the associated view.
Returns
Whether this ComponentTreeItem is currently hidden.

◆ Isolate()

void HPS.ComponentTreeItem.Isolate ( )
inline

This function will cause this ComponentTreeItem to be isolated, i.e., all other items will be hidden and this item will be shown. This will cause this item to be marked as visible if it isn't already, and all other items to be marked as hidden. Depending on the type of the ComponentTreeItem, sometimes an isolate is nonsensical. In this case, no isolate will be performed. When performing a highlight in combination with this function the highlight must be applied with Drawing.Overlay.InPlace to display properly.

◆ ObjectType()

override HPS.Type HPS.ComponentTreeItem.ObjectType ( )
inlinevirtual

This function returns the type the object, as declared (if the object is derived, this does not give the true type of the derived object).

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

Reimplemented from HPS.Object.

◆ OnHide()

virtual void HPS.ComponentTreeItem.OnHide ( )
inlinevirtual

This function will be invoked when this ComponentTreeItem should be marked as hidden. This hiding may have come as a result of the Hide or Isolate function on a ComponentTreeItem being invoked, or due to ComponentPath.Hide being invoked on the Component backing this ComponentTreeItem. This function is meant to be overridden to allow one to change the appearance of a hidden ComponentTreeItem, e.g., by graying the text or changing an icon, to signify this new state. If this function is overridden, the overriding function should invoke this base function.

Hide

◆ OnHighlight()

virtual void HPS.ComponentTreeItem.OnHighlight ( HPS.HighlightOptionsKit  in_options)
inlinevirtual

This function will be invoked when this ComponentTreeItem should be marked as highlighted. This highlighting may have come as a result of the Highlight function on a ComponentTreeItem being invoked, or due to ComponentPath.Highlight being invoked on the Component backing this ComponentTreeItem. This function is meant to be overridden to allow one to change the appearance of a highlighted ComponentTreeItem, 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.

Parameters
in_optionsThe HighlightOptionsKit for the associated highlight.

◆ OnShow()

virtual void HPS.ComponentTreeItem.OnShow ( )
inlinevirtual

This function will be invoked when this ComponentTreeItem should be marked as visible. This visibility may have come as a result of the Show or Isolate function on a ComponentTreeItem being invoked, or due to ComponentPath.Show or ComponentPath.Isolate being invoked on the Component backing this ComponentTreeItem. This function is meant to be overridden to allow one to change the appearance of a visible ComponentTreeItem, e.g., by no longer graying out the text or changing an icon, to signify this new state. If this function is overridden, the overriding function should invoke this base function.

Show

◆ OnUnhighlight()

virtual void HPS.ComponentTreeItem.OnUnhighlight ( HPS.HighlightOptionsKit  in_options)
inlinevirtual

This function will be invoked when this ComponentTreeItem should be marked as unhighlighted. This unhighlighting may have come as a result of the Unhighlight function on a ComponentTreeItem being invoked, or due to ComponentPath.Unhighlight being invoked on the Component backing this ComponentTreeItem. This function is meant to be overridden to allow one to change the appearance of a unhighlighted ComponentTreeItem, 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.

Parameters
in_optionsThe HighlightOptionsKit for the associated unhighlight.

◆ ReExpand()

void HPS.ComponentTreeItem.ReExpand ( )
inline

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

◆ ResetVisibility()

void HPS.ComponentTreeItem.ResetVisibility ( )
inline

This function will cause the visibility of this ComponentTreeItem to be reset to what is dictated by the associated CADModel & View. See this section for limitations and details on managing component visibility.

◆ Show()

void HPS.ComponentTreeItem.Show ( )
inline

This function will cause this ComponentTreeItem to be visible if it isn't already. Depending on the type of the ComponentTreeItem, sometimes a show is nonsensical. In this case, no show will be performed. If activated, this makes the selected path visibile but preserves the model-defined visibility of any components that exist underneath the associated ComponentPath. Any visibility changes made subsequently at or below this path are honored unless they are redundant. When performing a highlight in combination with this function the highlight must be applied with Drawing.Overlay.InPlace to display properly.
