Here's one possible solution (I believe):
x_margin = 5 ; Determine these empirically
y_margin = 25
device, get_screen_size=s_size
b = widget_base(xoffset=0, yoffset=0)
d = widget_draw(b, xsize=s_size(0), ysize=s_size(1))
widget_control, b, map=0
widget_control, b, /realize
widget_control, b, tlb_set_xoffset=-x_margin, $
tlb_set_yoffset=-y_margin
widget_control, b, /map
I don't know how you can determine the size of the margins and title
bar that the window system creates for the widget. This information
is not available using WIDGET_CONTROL, WID, /GEOMETRY.
Be aware that if you do this, you will have no way to kill the
widget! Put a "Cancel" button overlaid on the draw widget and
make a simple event handler so you can destroy your widget.
Hope this helps.
