LAnnContainer::LAnnContainer

Summary

Constructs and initializes the member variables of the LAnnContainer object.

Syntax

#include "ltwrappr.h"

LAnnContainer::LAnnContainer()

LAnnContainer::LAnnContainer(hContainer)

LAnnContainer::LAnnContainer(hWnd, pRect, bVisible)

Parameters

HANNOBJECT& hContainer

Handle of the associated annotation object.

HWND hWnd

Handle to the window for the container.

pANNRECT 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.

L_BOOL 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.

Example

//This is an example for LAnnContainer::LAnnContainer() : 
L_INT LAnnContainer_LAnnContainerFisrtExample() 
{ 
 
   // this will call the default constructor and destructor when it is out of scope 
   LAnnContainer LeadAContainer ; 
 
   //... 
   return SUCCESS; 
} 
 
//This is an example for LAnnContainer::LAnnContainer(hWnd, pRect, bVisible): 
 
L_INT LAnnContainer_LAnnContainerSecondExample(HWND hWnd) 
{ 
   L_INT nRet; 
   ANNRECT AnnRect ; 
 
   AnnRect.left = 10 ; 
   AnnRect.top = 10 ; 
   AnnRect.right = 60 ; 
   AnnRect.bottom = 60; 
 
   // this will call the default constructor and destructor when it is out of scope 
   LAnnContainer LeadAContainer(hWnd,&AnnRect,TRUE) ; 
    
   //... 
 
   nRet = LeadAContainer.SetUserMode(ANNUSER_RUN); 
   if(nRet != SUCCESS) 
      return nRet; 
 
   //... 
   return SUCCESS; 
} 
 
//This is an example for LAnnContainer::LAnnContainer(hContainer): 
 
L_INT LAnnContainerThirdExample(HANNOBJECT& hContainer) 
{ 
 
   // this will call the default constructor and destructor when it is out of scope 
   LAnnContainer LeadAContainer(hContainer) ; 
 
   //... 
   return SUCCESS;
