# Description

Handle the resizeStack message if you want to update the position of objects or do other tasks when the stack window changes size.

The resizeStack message is sent when the user resizes the stack by dragging its size box. It is also sent if a handler changes the size of the stack by changing its properties (width, height, and so on).

The resizeStack message is sent after the resizing is finished. This means that you cannot prevent a stack size from being changed by trap this message.

The pOldWidth and pOldHeight for each resizeStack message is the same as the pNewWidth and pNewHeight for the previous resizeStack. The stack original width and height are passed only with the first resizeStack message sent during a resize operation.

The screen is locked while a resizeStack handler is running, so it is not necessary to use the lock screen command to prevent changes from being seen. (However, the lockScreen property is not set to true.)

>*Note:* If the stack's vScroll property is nonzero, the amount of > scroll is not included in the pNewHeight and pOldHeight. This means > that the parameters of the resizeStack > message are always equal to the stack's height before > and after resizing, regardless of the vScroll setting.

>*Known issue:* Currently errors in moveStack and resizeStack are > ignored, as this was causing a hang in the IDE.
