You have to obtain the handle of the window you want focus in then call set focus on that handle. From Gtk+ in X I can do this:
XRaiseWindow(GDK_DISPLAY(), (Window) x_win);
XSetInputFocus(GDK_DISPLAY(), (Window) x_win), RevertToParent,
CurrentTime);
The calls for windows may be different.
Gentle reminder: When posting snippets of code to PM they look nicer if you put < code></code> around the snippit. Like this:
$ppc = Win32::Process::Create(
$global_process,
$command_a,
$command_b,
0,
NORMAL_PRIORITY_CLASS,
'.'
);
s//----->\t/;$~="JAPH";s//\r<$~~/;{s|~$~-|-~$~|||s
|-$~~|$~~-|||s,<$~~,<~$~,,s,~$~>,$~~>,,
$|=1,select$,,$,,$,,1e-1;print;redo}
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
Read Where should I post X? if you're not absolutely sure you're posting in the right place.
