Cool, indeed.
I dont appear to have stroke support compiled into mine, but I was
able to create an effect sort of like what you describe. I use
FvwmEvent in conjunction with a variable to decide whether or not to
immediately resize the last window created. Then I bind the middle
mouse button to set that variable and to spawn an xterm at the cursor
position.
##### .fvwm2rc modifications #####
# set default to not resize new windows
SetEnv doResizeStuff false
Mouse 2 R A PlaceTermWithResize
DestroyFunc PlaceTermWithResize
AddToFunc PlaceTermWithResize
+ H Exec exec xterm -geom 10x1+$[pointer.x]+$[pointer.y]
+ H SetEnv doResizeStuff True
#following requires that FvwmEvent has been started already
*FvwmEvent: add_window CheckXtermResize
DestroyFunc CheckXtermResize
AddToFunc CheckXtermResize
+ I Test ($[doResizeStuff]) Resize
+ I SetEnv doResizeStuff False

To use it, you click the middle mouse button, drag diagonally, release
the button at any time, and click again to set the lower right bounds.
I use M instead of I in PlaceTermWithResize because it seemed slightly
more correct in appearance. Not entirely correct. With I, you had to
click to do the resize. With M, it's already doing the resize, but
you have to let go of the button before it will show you the
outline... and then you have to click again for it to finish the
resize.
--s.r.d.
p.s.: Oops! I did a reply to the wrong address the first time around...
