LAnimationWindow::SetPosition

#include "ltwrappr.h"

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

L_INT nLeft;	/* x coordinate for the bitmap list item */
L_INT nTop;	/* y coordinate for the bitmap list item */
L_UINT nIndex;	/* position of the bitmap list item */

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

Parameter	Description
nLeft	X coordinate for the origin of the bitmap list item.
nTop	Y coordinate for the origin of the bitmap list item.
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

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.

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.
