How to set a GUI to be " Always @ Bottom " ? http://www.autohotkey.com/forum/viewtopic.php?p=54403#54403 I might be technically incorrect -
but in layman terms,
"
Always On Top" window will never be below any other window - and
"
Always At Bottom" window will never be above any other window
because its a
"Child window" of the Desktop.The "
sticking of the GUI" is achieved by a
DllCall to
User32.dll function "
SetParent"
which sets the GUI to be the child window of Desktop.
Reference / CreditsWell. I was never comfortable with
DllCall(), but for
evl &
Serenity ( & others ) who helped me to understand this
particular function on
Ask for Help topic :
Is there a way to write "Text" on Desktop, above Wallpaper ?You may view
Serenity's Post.
evl has posted it in
Script & Functions titled :
SetParent function (make a gui belong to another window).
I was hesitant in posting this but I had already written a demo ...
Always @ Bottom - How to ?Add the following line immediately after
Gui, ShowCode:
WinSet:=AlwaysAtBottom(WinExist("A"))
and include the
AlwaysAtBottom() function in your script
Code:
AlwaysAtBottom(Child_ID)
{
WinGet, Desktop_ID, ID, ahk_class Progman
Return DllCall("SetParent", "uint", Child_ID, "uint", Desktop_ID)
}
and thats it ....
The use?You can make a GUI - a ToolWindow - without a Title bar - exactly the size of your desktop -
make this GUI always @ bottom - add small pictures to it - associate programs to these pictures
with gLabel - and what not ? This GUI will not be minimizeable and desktop will not be accessible
till this GUI is closed.
A VIRTUAL DESKTOP ?The Demo!
<O>
Seen above is a small
timer-based clock that will be stuck on Desktop.
I have applied the "
Shadowed Text" effect that I have explained in my previous post.

Just add these two lines in the beginning when coding a GUI:
Code:
Gui, +Lastfound
DllCall("SetParent", UInt, WinExist() , UInt, WinExist("Program Manager"))
.. and that would suffice !
Copy / Paste / Try Example:
Code:
Gui, +Lastfound
DllCall("SetParent", UInt, WinExist() , UInt, WinExist("Program Manager"))
Gui, Show, w400 h300, This GUI is a Child Window of Desktop
