LAnnPushPin::SetBitmap

Summary

Sets the bitmap of the annotation object.

Syntax

#include "ltwrappr.h"

virtual L_INT LAnnPushPin::SetBitmap(pBitmap, uFlags=0)

Parameters

LBitmapBase * pBitmap

Pointer to the bitmap object referencing the bitmap object to assign to the specified object.

pBITMAPHANDLE pBitmap

Pointer to the bitmap handle referencing the bitmap to assign to the specified object.

L_UINT uFlags

Flags that determine which objects to process. Most of the flags apply only to container objects. You can combine values when appropriate by using a bitwise OR ( | ). The following are valid values:

Value	Meaning
0	Process only the specified object.
ANNFLAG_SELECTED	[0x0001] Process only objects that have the selected property set to TRUE. For getting and setting the selected property, use the LAnnotation::IsSelected and LAnnotation::SetSelected functions.
ANNFLAG_NOINVALIDATE	[0x0010] Do not invalidate the affected rectangle in the window. Use this to avoid generating unwanted paint messages.

Comments

A pushpin object has a primary bitmap, (manipulated using LAnnPushPin::SetBitmap/LAnnPushPin::GetBitmap) when the text is shown, and a secondary bitmap, manipulated using LAnnPushPin::SetSecondaryBitmap / LAnnPushPin::GetSecondaryBitmap. The primary bitmap is shown with the note text. The secondary bitmap is shown by itself when the note is minimized.

In design mode, the PushPin object shows the text and displays the primary bitmap. In run mode, the object shows/hides the text when clicked. The pushpin object has the active mode property. When the mode is ANNACTIVE_ENABLED, the text is shown and the primary bitmap is painted in the top-left corner of the note.

When the mode is ANNACTIVE_DISABLED, the text is hidden and the secondary bitmap is displayed.

Returns

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

Example

This is an example for both forms of LAnnPushPin::SetBitmap(pBitmap, uFlags=0):

//This example sets the primary and secondary images of a pushpin 
 
//The pushpin is displayed.  The image (primary or secondary) displayed 
 
//depends on the state of the boolean 'm_bPrimary' 
//***IMPORTANT: In the OnPaint(), add the following code: 
//      RECT rect; 
//      m_AnnContainer.GetBoundingRect(&rect) ; 
//      HDC hdc = ::GetDC(m_hWnd); 
//      m_AnnContainer.Draw(hdc,&rect); 
//      ::ReleaseDC(m_hWnd, hdc); 
 
LAnnContainer m_AnnContainer; 
L_BOOL m_bPrimary;

   LBitmap MyBitmap; 
   ANNRECT annRect; 
 
   LAnnPushPin *pMyAnnPushPin = new (LAnnPushPin); 
 
   annRect.left = 50; 
   annRect.top = 50; 
   annRect.right = 170; 
   annRect.bottom = 170; 
   pMyAnnPushPin->SetRect(&annRect); 
   pMyAnnPushPin->SetVisible(TRUE); 
 
   //Set pushpin properties 
   LBitmapBase MyBitmapBasePrimary; 
   MyBitmapBasePrimary.Load(MAKE_IMAGE_PATH(TEXT("IMAGE1.CMP"))); 
   pMyAnnPushPin->SetBitmap(&MyBitmapBasePrimary,0); 
   //or 
   //pMyAnnPushPin->SetBitmap(MyBitmapBasePrimary.GetHandle(),0); 
 
   LBitmapBase MyBitmapBaseSecondary; 
   MyBitmapBaseSecondary.Load(MAKE_IMAGE_PATH(TEXT("IMAGE2.CMP"))); 
   pMyAnnPushPin->SetSecondaryBitmap(&MyBitmapBaseSecondary,0); 
   //or 
   //pMyAnnPushPin->SetSecondaryBitmap (MyBitmapBaseSecondary.GetHandle(),0); 
 
   //Create container and insert annotation 
   m_AnnContainer.Create(hWnd, &annRect, TRUE); 
   m_AnnContainer.Insert(*pMyAnnPushPin); 
   m_AnnContainer.SetUserMode(ANNUSER_RUN); 
 
   if (m_bPrimary) 
      //Draw pushpin with primary bitmap 
      pMyAnnPushPin->SetActiveState(ANNACTIVE_ENABLED); 
   else 
      //Draw pushpin with secondary bitmap
