LAnnContainer::LAnnContainer()
LAnnContainer::LAnnContainer(hContainer)
LAnnContainer::LAnnContainer(hWnd, pRect, bVisible)
Constructs and initializes the member variables of the LAnnContainer object.
Handle of the associated annotation object.
Handle to the window for the container.
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.
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. |
None.
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.
Win32, x64.
