Detailed Description

Textbox gadget: base class for handling text.

The main purpose of this class is to display text that changes dynamically. Use UTextfield to edit a single line of text and UTextarea to edit multi-line text regions.

In contrast with most UBox objects, the width of UTextbox, UTexfield and UTextarea objects do not change when their content is modified (they keep their initial size). This may provide a more stable layout and will improve performance. See UWidth and UHeight for more details or to change this behavior.

Other default Properties:

• the layout is horizontal (add: UOrient::vertical otherwise).
• the font and the foreground color are inherited from parents.
• the background is transparent

Example:

      UStr& msg = ustr("Segmentation fault");
      UTextbox& tbox = utextbox( UPix::ray + "Error: " + s );
      msg = "Bus error";    // changes 'msg' and updates 'tbox'
