特性文檔編製

background : Item

此特性保持背景項。

注意： If the background item has no explicit size specified, it automatically follows the control's size. In most cases, there is no need to specify width or height for a background item.

注意： Most controls use the implicit size of the background item to calculate the implicit size of the control itself. If you replace the background item with a custom one, you should also consider providing a sensible implicit size for it (unless it is an item like Image which has its own implicit size).
