Hi all,
Sometime ago I've written a smart object, that is very similiar to
Esmart_Draggies, actually I started to modify a copy of draggies. The
purpose of this object is to resize a borderless window. You can set, in
which directions it will resize the window. I named it Esmart_Resize.
Find a patch attached and a test app here: mowem.de/esmart/esr.tar.bz2.
Please let me know if you find it useful and I will commit it.
pfritz
P.S. Sorry that I already commit the subdir. I wonder if it is possible
to add a dir with out committing it.
