Focusing

New in GLBasic 9.054 is the ability to move backwards or forwards through either a text or single text widget.  This is done by using :

DDgui_advancefocus([direction% = -1])

This moves the cursor to either the next text or single text widget (direction% > 0) or the previous widget (direction% < 0)

Ddgui_setfocus(id$)

This moves the cursor to the widget defined by id$.  Again, this only works with text or single text widgets.
