LAnnContainer::LAnnContainer()

LAnnContainer::LAnnContainer(hContainer)

LAnnContainer::LAnnContainer(hWnd, pRect, bVisible)

HANNOBJECT& hContainer;

handle of the associated annotation object

HWND hWnd;

handle to the window

pANNRECT pRect;

pointer to a structure

L_BOOL bVisible;

flag that indicates whether the container will be visible

Constructs and initializes the member variables of the LAnnContainer object.

Parameter Description
hContainer Handle of the associated annotation object.
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 or not. Possible values are:
  Value Meaning
  TRUE The container is visible (although transparent).
  FALSE The container is not visible.

Returns

None

Comments

LAnnContainer::LAnnContainer() is the default constructor for the LAnnContainer class.

LAnnContainer::LAnnContainer(hWnd, pRect, bVisible) creates the associated Container annotation object with the specified bounding rectangle and window handle.

LAnnContainer::LAnnContainer(hContainer) attaches the passed handle to the created class object. The passed handle must be a LEAD annotation object of type ANNOBJECT_CONTAINER. The passed annotation object is invalidated.
