The Appearance tab of the Properties view enables you to edit the alignment, indentation, size, and span of a widget.
Alignment
The Alignment property is used to position a widget within its parent container, the cell, not the form. If you want to position the widget on the left of the form, you can expand the cell as wide as the form.
Size
The Size property is used to set the height and width of a widget.
Note You can also edit the size by dragging the boundaries of the widget in the XUI editor area. The Auto Size checkbox is automatically cleared when the resizing handle is grabbed.
Fixed
Check fixed and set the value by px.
Relative
Check relative and set the percent value. There are some widgets not supported and it is relative to its parent container, the cell, not the form. For more information, see Setting the relative width and height of a widget.
Auto-sized
Check Auto-sized.
It is used to display single line of text.
TextWrap (width)
For widgets with text, such as label, link, checkbox, radio, button, and message, width has another property, TextWrap.
