LAnimationWindow::SetPosition

Summary

Sets the left and top positions for the bitmap item at position nIndex inside the bitmaplist.

Syntax

#include "ltwrappr.h"

L_INT LAnimationWindow::SetPosition(nLeft, nTop, nIndex=ANIM_ALL_ITEMS)

Parameters

L_INT nLeft

X coordinate for the origin of the bitmap list item.

L_INT nTop

Y coordinate for the origin of the bitmap list item.

L_UINT nIndex

Position of bitmap list item. Possible values are:

Value	Meaning
ANIM_ALL_ITEMS	[-1] Set the delay for all items in the bitmap list
>=0	Set the delay only for the specified item

Returns

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

Comments

If nIndex = ANIM_ALL_ITEMS, then all bitmap list items will be affected by the new position.

Required DLLs and Libraries

Example

This example iterates through all bitmap items, gets the current position
for each bitmap using GetPosition method, displays it, sets the new
position using SetPosition so that the images will be shifted diagonally.
