How to set Button, tab with auto width?

[ottcan]

The default setting for button and tab's width is fixed, how to set the buttons and tabs with auto width, which means the width should depend on how many characters on the button/ tab?

Thanks,

I am also curious if this is at all possible. Is tehre anyone out there with the answer?

Sure. Tabs support variable widths based on title by default. A button has an autoFit property to enable that feature.
