List of all members.

Public Member Functions
	CBrushEditDlg ()
	Default constructor for CBrushEditDlg.
	~CBrushEditDlg ()
	Destructor.
void	Do (OpDescriptor *)
	launches the brush edit dialog, this method will determine which brush it is editing from the document selection.
void	DoWithParam (OpDescriptor *, OpParam *OwningGadgetParams)
	launches the brush edit dialog, however this the BrushData to initialise the dialog is provided through the opparam. Note: I don't think that we use this method anymore.
virtual MsgResult	Message (Msg *)
	Message proc for this dialog.
void	CreateNewBrush ()
void	HandleBrushEditSpacingMsg (DialogMsg *Msg)
	Subhandler for messages from the spacing tab, except for the edit box and sliders, which have their own handlers.
void	HandleBrushEditOffsetMsg (DialogMsg *Msg)
	Subhandler for messages from the offset tab, except for the edit box and sliders, which have their own handlers.
void	HandleBrushEditScalingMsg (DialogMsg *Msg)
	Subhandler for messages from the scaling tab, except for the edit box and sliders, which have their own handlers.
void	HandleBrushEditEffectMsg (DialogMsg *Msg)
	Subhandler for messages from the rotation tab, except for the edit box and sliders, which have their own handlers.

void	HandleBrushFillMsg (DialogMsg *Msg)
	Subhandler for messages from the fill tab, except for the edit box and sliders, which have their own handlers.
void	InvokeVia (CBrushGadget &pInvokeWith, BrushData *pInvokeOn, AttrBrushType *pBrush, BOOL &bMany)
	I'm not entirely sure what this does, perhaps Chris will be able to elaborate, I think they were once used as part of launching the dialog, but I think they are no longer used.
void	InvokeVia (CBrushGadget &pInvokeWith, BrushData *pInvokeOn, AttrBrushType *pBrush, AttrBrushType *pOrigBrush, BOOL &bMany)
void	InvokeVia (CBrushGadget &pInvokeWith, BrushHandle Handle)
virtual BOOL	RegisterYourPagesInOrderPlease ()
	This virtual function will get called to give you a chance to add pages to your DialogTabOp. This function will usually make multiple calls to AddAPage to register the initial set of pages to be contained in the tab dialog. The pages should all be the same size and be registered in the left to right order in which you wish them to appear.
void	ReInitialiseDialog (BrushData *pData)
void	SetDialogTitle (String_256 Title)
Static Public Member Functions
static BOOL	Init ()
	the init function to register us as an Op
static OpState	GetState (String_256 *, OpDescriptor *)
	Determines whether or not we can launch this op. We are allowed to launch in the following circumstances: Any tool, one AttrBrushType in the selection FreeHandTool, as above OR brush selected in the brush combo and no document selection.
