Hi All,
Dumb widget question #547:
How do you position widgets on the screen? Every time I run the
procedure, the baseId appears in a different location, sometimes covered
up by another window.
Thanks!
Patty

Hy, again,
What do you refer to by window-number? If you think of the complete
widget (defined by the widget_base function and all subsequent
child widgets), you have the window number, better widget ID by
wid_base_0 in the example above. If you have a draw window inside
this widget group, then you get this via (example only):
uvalue = {UVALUE,$
xsize:0L,$
ysize:0L,$
draw_window:0L}
base = WIDGET_BASE( TITLE = 'I love Y2k',$
/COLUMN, $
XPAD = 10, YPAD = 10, $
SPACE = 10)
draw = WIDGET_DRAW(base,$
XSIZE = uvalue.xsize, YSIZE = uvalue.ysize,$
RETAIN = 2, $
/BUTTON_EVENTS)
WIDGET_CONTROL, draw, GET_VALUE = tmp
uvalue.draw_window = tmp
wset,uvalue.draw_window
here uvalue.draw_window contains the number of the draw widget.
I use this structure because I can put this then into the
UVALUE of the base widget:
WIDGET_CONTROL, base, SET_UVALUE=PTR_NEW(uvalue),/NO_COPY
and use this easily in subroutines afterwards.
