Tab width: I have a problem with a tabbed dialog. I use the BoxSize command to display a larger group box with additional fields, but the tab frame is not appropriately resized.

In older GuiXT versions GuiXT did not increase the tab width automatically when you worked with BoxSize. A workaround here would be to add an empty text element at the right hand side of the group box; the tab width will then be increased so that the empty text is included. Example:

BoxSize G[General data] (10,160)

Text G[General data]+(0,161) " "
