LAnnContainer::SetSecondaryBitmap

#include "ltwrappr.h"

virtual L_INT LAnnContainer::SetSecondaryBitmap(pBitmap, uFlags)

pBITMAPHANDLE pBitmap;	pointer to the bitmap handle
LBitmapBase * pBitmap;	pointer to an LBitmapBase object
L_UINT uFlags;	flags that determine the object to process

Sets the secondary bitmap of the container object.

Parameter	Description
pBitmap	Pointer to the bitmap handle referencing the secondary bitmap to assign to the specified object.
pBitmap	Pointer to the bitmap object referencing the secondary bitmap object to assign to the specified object.
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.
	ANNFLAG_CHECKMENU	[0x0020] Process objects only if the ANNAUTOTEXT_MENU_SECONDARYFILE menu item has been selected.

Returns

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

Comments

A container object has a primary bitmap, (manipulated using LAnnContainer::SetBitmap) when the text is shown, and a secondary bitmap, manipulated using LAnnContainer::SetSecondaryBitmap. 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 container object shows the text and displays the primary bitmap. In run mode, the object shows/hides the text when clicked. The container 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.
