LAnnContainer::Create

#include "ltwrappr.h"

virtual L_INT LAnnContainer::Create(hWnd, pRect, bVisible=FALSE)

HWND hWnd;	/* handle to the window */
pANNRECT pRect;	/* pointer to a structure */
L_BOOL bVisible;	/* flag that indicates whether the container will be visible */

Creates and initializes an annotation object that is a container.

Parameter	Description
hWnd	Handle to the window for the container.
pRect	Pointer to the LEADTOOLS ANNRECT structure that specifies the container. The ANNRECT structure is like a Windows RECT structure, except that it uses double-precision floating point values.
	Coordinates of an object's rectangle are relative to its container object. The coordinates are interpreted using the container's scaling factors and offsets, which are described in Low-Level Coordinate System for Annotations.
bVisible	Flag that indicates whether the container will be visible. Possible values are:
	Value	Meaning
	TRUE	The container is visible.
	FALSE	The container is not visible.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

You should not call this function during processing of WM_LTANNEVENT if wParam equals LTANNEVENT_REMOVE or LTANNEVENT_INSERT or during the LAnnContainer::EnumerateCallBack virtual function!
