Tab-Widths
This property is used to set the width, in cells, of the tab identified by the Tab-Index property.
The tab width is applicable only to Tab-Controls with the Tab-Flat style and without the Accordion style.
When values are enclosed between parentheses, the Tab-Index property is ignored, the 1st value refers to the 1st panel, the 2nd value refers to the 2nd panel and so on.
