window on aqua without a titlebar

[Mike Ignatoski]

Tcl/Tk,

I am trying to create a top-level window that does NOT have a titlebar.

I have the following code:

$img_hover{win} = $mw->new_toplevel();
$img_hover{win}->g_wm_title ( "Balloon Card Image" );
$img_hover{win}->g_wm_iconbitmap ( $CONSTANTS{APP_ICON} );
$img_hover{win}->g_wm_geometry("$PM_CONSTANTS{BALLOON_IMG_X}x$PM_CONSTANTS{BALLOON_IMG_Y}");

$img_hover{win}->g_wm_resizable(0, 0); # make window size fixed,
not resizable
$img_hover{win}->g_wm_overrideredirect ( 1 );

on Win32, it works fine
on aqua, the window always has a titlebar

In addition, I'm using the window as a tooltip/balloon hover window, so
when it's shown, I never want it to have the "focus". When I deiconfy
it on Win32, it works great, but on OS X (aqua), it shows the window and
also grabs the focus, so I have to click on the main app to return focus.

Any insight is appreciated.

Thanks,
Mike

ps, I believe I'm using Tcl 8.5.8

The Tcl/Tk code on Aqua to achieve the effect you want looks something
like this:

if {[string equal [tk windowingsystem] aqua]} {
::tk::unsupported::MacWindowStyle style $top help none
}

where $top is a toplevel window. That doesn't grab focus.

Thanks a lot, Kevin! It worked great....once I figured out that I had to
put that code immediately after creating the toplevel window. If I
placed the code after doing anything else with toplevel, such as setting
it's geometry, it didn't work.

Thanks, again!
Mike

ps that was fast!

Glad it was helpful, and I'm also glad you figured out when to place the
code--that's a little tricky to get right under Aqua, especially under
the new Cocoa bindings to Tk.
