background : Item |
此特性保持背景项。
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 图像 which has its own implicit size).
