: I'm sorry to be such a pest but I can't find the code in nanowm that does
: this.
the file actions.c::topbar_mousemoved() is called when the mouse
moves and is down in the caption of a window. (Remember, nanowm
"reparents" windows by giving them a parent, in which it draws
the "window decorations"
Is there any documentation on how to use nanowm from another program
: or is it used as a base to build your own programs on?
No, the source is the only real documentation. The window manager
is a bit different from other programs, but could easily be used as a base
for more/less enhancements. This is what we did with the window
mgr in pixil.org.
Regards,
Greg
