ILayoutNode
Basic functionality implemented by all types of Layout Nodes. Layout nodes are expected to realize this interface. Specific layout node classes may specialize this interface to provide additional functionality.Defined in: LayoutBase.h
Methods
virtual int GetChildrenCount
Returns the number of child nodes this node has.
virtual ILayoutNode* GetParentNode
Returns this node's parent node.
virtual void SetParentNode
Set this node's parent node.
virtual ILayoutNode* GetRootParentNode
Returns the root node of the layout tree.
virtual int AddLayoutNode
Adds the layout node pointed by pNode to the list of this node's children.
virtual int RemoveLayoutNode
Removes the layout node pointed by pNode from the list of this node's children.
virtual Iterator* GetChildNodesIterator
Returns an iterator to traverse the collection of child nodes.
ILayoutNode* FindChildNode
Return the first child node whose Id is equal to the parameter nId.
Properties
GUID* GetGUID
Returns a GUID that identifies the exact class this object is an instance of.
Methods
virtual bool IsVisible
Returns the node's visibility state
Properties
CSize,CSize Get/SetMinMaxSize
Gets/Sets the minimum/maximum node size information.
bool SetRecalcDirty
Marks as clean/dirty for position recalculation.
bool Set/IsInvalidateDirty
Returns or sets whether this node needs an invalidation operation to be performed.
DWORD Get/Set/ModifyNodeExStyle
Retrieves or sets the extended style of the node.
bool Get/SetLockRealizeNode
Prevents the RealizeNode operation from being processed in this node. Useful for redraw optimizations.
Methods
Queries the number of child items to be drawn by a DeferWindowPos call in RealizeNode
Properties
bool IsNodeAttached
Returns whether this node is attacched to a realizable screen element, e.g. a window.
long GetNodeId
Returns the Id of the element associated with this node.
int,int Get/SetNonClientOffset
Returns or sets the offset value for positioning nodes relative to a nonclient area
bool Get/SetNodeHorizontal
Sets the base node orientation setting.
CRect Get/SetInitialRect
Retrieves or sets the rectangle initially occupied by the node.
CRect Get/SetInitialRect
Retrieves or sets the rectangle the node would prefer to occupy.
CRect Get/SetCurrentRect
Retrieves or sets the rectangular area the node is currently responsible for.
CRect Get/SetOldRect
Retrieves or sets the rectangular area the node used to occupy before the previous RecalcLayout() operation.
CRect Get/SetInvalidateRect
Retrieves or sets the rectangular area the node requests to be invalidated for the next drawing operation.
Methods
Constrains the passed rectangle to the maximum and minimum dimensions specified for the node using a call to ILayoutNode::Get/SetMinMaxSize().
void Init
Initializes this layout node.
void Show
Shows or hides the visible elements associated with the node.
CRect RecalcLayout
Performs the layout recalculation operation
bool RealizeNode
Realizes the changes in position and size of the layout node as calculated in a recent execution of the ILayoutNode::RecalcLayout operation
void OptimizedRedraw
Optimized drawing. Called at the end of the realization process to perform any painting logic that have been deferred until the last moment. Descendent layout classes should implement this operation if it is justified to prevent flicker or other painting problems.
bool PerformInvalidation
Invalidates the area indicated by the node's invalid rectangle.
bool EraseNodeBkgnd
Erases the background of the rectangular area assigned to the node. Usually called as part of the processing of the WM_ERASEBKGND windows message.
void PaintNode
Performs all necessary display operations. Usually called as part of the response to the WM_PAINT message.
