The use of appearance mode has been introduced in StringItem.
Public Spacer (INT MinWidth, Int MinHeight), Spacer class is set to item.Layout_expand in this program, which is filled with the remaining blank section. In this way, you can see that the two imageitem objects are located on both ends and layout.
