Public Methods

Method	Description
CheckDisposed ( ) : void	Check to see if the object has been disposed. All public Properties and Methods should call this before doing anything else.
HandleSizeChanged ( object sender, EventArgs ea ) : void
SliceTreeNode ( Slice slice ) : System
ToggleExpansion ( int iSlice ) : void	Toggle the expansion state of the slice at iSlice. May presume it is already in existence. (If it is in the collapsedEmpty or fixed states, do nothing.)
ToggleExpansionAndScroll ( int iSlice ) : void	Toggle the expansion state of the slice at iSlice. May presume it is already in existence. Todo: attempt to scroll so new children are visible

Protected Methods

Method	Description
Dispose ( bool disposing ) : void	Clean up any resources being used.
OnDoubleClick ( EventArgs e ) : void	Double-click causes expand/contract wherever it is.
OnDragDrop ( DragEventArgs drgevent ) : void
OnDragEnter ( DragEventArgs drgevent ) : void
OnMouseDown ( MouseEventArgs meArgs ) : void	Preliminary version of mouse down handles expansion and contraction. Todo: - Scroll appropriately to show as much as possible of what was expanded. - drag and drop effects. - double-click on label also toggles expansion.
ProcessDialogChar ( char charCode ) : bool	Activate menu only if Alt key is being pressed. See FWNX-1353. TODO: Getting here without the Alt key may be considered a Mono bug.

Private Methods

Method	Description
HandlePaint ( object sender, PaintEventArgs pea ) : void
InitializeComponent ( ) : void	Required method for Designer support - do not modify the contents of this method with the code editor.
OkToMove ( int hvoDstOwner, int flidDst, int ihvoDstStart, ObjectDragInfo odi ) : bool
SliceTreeNode_KeyDown ( object sender, System e ) : void
SliceTreeNode_KeyPress ( object sender, System e ) : void
TestDropEffects ( DragEventArgs drgevent, int &hvoDstOwner, int &flidDst, int &ihvoDstStart ) : ObjectDragInfo	Test whether we can drop the information indicated by the drgevent onto this. Currently this is possible if 1. The drag event's data is an ObjectDragInfo 2. It is valid for those objects to be moved to a position just after the object of which the destination slice is a part, in the lowest level sequence of which it is a part. drgevent.Effect is set to Move or None to indicate the result. If successful, returns an ObjectDragInfo and the place to put the new objects. (Note: the ihvoDstStart returned is meaningless if the property is a collection.) Move is valid under the following conditions: 1. Must not violate signature. Signature is checked if destination property is different from source. 2. Must not create circularity of ownership. This is checked if destination object is different from source. 3. Must result in actual movement. This is checked if destination and source object and flid are the same. This case always fails if the property is a collection, also if it is a sequence and nothing would change.

Method Details

CheckDisposed() public method

Check to see if the object has been disposed. All public Properties and Methods should call this before doing anything else.

public CheckDisposed ( ) : void
return	void

Dispose() protected method

Clean up any resources being used.

protected Dispose ( bool disposing ) : void
disposing	bool
return	void

HandleSizeChanged() public method

public HandleSizeChanged ( object sender, EventArgs ea ) : void
sender	object
ea	System.EventArgs
return	void

OnDoubleClick() protected method

Double-click causes expand/contract wherever it is.

protected OnDoubleClick ( EventArgs e ) : void
e	System.EventArgs
return	void

OnDragDrop() protected method

protected OnDragDrop ( DragEventArgs drgevent ) : void
drgevent	System.Windows.Forms.DragEventArgs
return	void

OnDragEnter() protected method

protected OnDragEnter ( DragEventArgs drgevent ) : void
drgevent	System.Windows.Forms.DragEventArgs
return	void

OnMouseDown() protected method

Preliminary version of mouse down handles expansion and contraction. Todo: - Scroll appropriately to show as much as possible of what was expanded. - drag and drop effects. - double-click on label also toggles expansion.

protected OnMouseDown ( MouseEventArgs meArgs ) : void
meArgs	MouseEventArgs
return	void

ProcessDialogChar() protected method

Activate menu only if Alt key is being pressed. See FWNX-1353.

TODO: Getting here without the Alt key may be considered a Mono bug.

protected ProcessDialogChar ( char charCode ) : bool
charCode	char
return	bool

SliceTreeNode() public method

public SliceTreeNode ( Slice slice ) : System
slice	Slice
return	System

ToggleExpansion() public method

Toggle the expansion state of the slice at iSlice. May presume it is already in existence. (If it is in the collapsedEmpty or fixed states, do nothing.)

public ToggleExpansion ( int iSlice ) : void
iSlice	int
return	void

ToggleExpansionAndScroll() public method

Toggle the expansion state of the slice at iSlice. May presume it is already in existence. Todo: attempt to scroll so new children are visible

public ToggleExpansionAndScroll ( int iSlice ) : void
iSlice	int
return	void
