pBitmap

Pointer to the bitmap handle that references the secondary bitmap.

Comments

Only PushPin objects use a secondary bitmap.

A pushpin object has a primary bitmap, (manipulated using L_AnnSetBitmap/L_AnnGetBitmap) when the text is shown, and a secondary bitmap, changed using L_AnnSetSecondaryBitmap. 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.
