This morning I had an idea to create a workaround for the lack of the
position parameters. When dialog_pickfile() has a parent, specified by
the dialog_parent keyword, the start position is identical with that
of the parent. (This is my observation, if the parent is a top level
base.) The upper-left of dialog_pickfile matches with the upper-left
of the parent. The parent can be made unvisible and everything looks
fine:
tlb_wid=widget_base(xoffset=300,yoffset=200)
widget_control,tlb_wid,map=0
widget_control,tlb_wid,/realize
help,dialog_pickfile(dialog_parent=tlb_wid)
widget_control,tlb_wid,/destroy
Of cause, this way of positioning works only on the first time calling
dialog_pickfile in the IDL session, since dialog_pickfile remembers
its last position. However dialog_pickfile is gone from the upper-left
corner.
Note that dialog_pickfile also remembers its position, after a full
reset of the IDL session. Be careful when testing. :-)

I am happy, saying not to have this complaints (at this time).
