No problem.
Use the map keyword in the call to the widget creation function
(e.g. widget_base()) and/or the widget_control procedure.
map=0 means don't show it
map=1 means show it.

;Create a base, but don't show any widget created off of this base yet.
baseWidget = widget_base(title=baseWidgetTitle, map=0)

;Add a draw widget to the base.
mainDrawWidget= widget_draw(baseWidget, xsize=imageSizeX, ysize=imageSizeY)

;Realize the widget, but it's still not shown to the user 'cause map still
set to 0.
widget_control, baseWidget, /realize

;OK, show it to 'em by setting map=1
widget_control, baseWidget, map=1

;Now go ahead and hand off to xmanager
xmanager, "mainForm", baseWidget, /no_block

Wow, looky here! Now *I'm* posting answers to questions. I must be finally
gettin'
the hang of this stuff.

Good luck
