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

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.
