Can't remove Titlebar

I can't create a windowed but titlebar-less Blitz window.

I've done a search on the forums but still can't find what I need.

This works fine to create a standard window: \/
hWnd = DLLFindBlitzRuntimeHwnd(ProgName$)
WindowStyle = WS_VISIBLE + WS_BORDER + WS_MINIMIZEBOX + WS_MAXIMIZEBOX + WS_SIZEBOX + WS_SYSMENU
User32_SetWindowLong(hWnd,GWL_STYLE,WindowStyle)

To get rid of the Titlebar, if this was C, all I would have to do is change to:
WindowStyle = WS_VISIBLE

But all I get is a dead, blank window.
In fact any combination of flags other than the top WidowStyle def causes a blank window.

Please don't suggest that I use SetWindowRgn - that just clips the region and I lose the bottom 20 pixels.

Any ideas, please?

Probably it has something to do that (AFAIK) blitz is using some kind of canvas for Graphics and Graphics3D, and the runtimeHWND is not the same as the canvas handle?

I remember it was possible to remove the titlebar with the Blitzsys.dll.

Thanks jfk, but... ah, no.
I've been through every example that comes with BlitzSys.

As I said, the only method shown is SetWindowRgn (for skinning etc) but unfortunately that method removes the bottom 20 pixels (caption height?) from the window - which happens to be where my controls are displayed.

Surely someone has done this - by another method?

I can do it in BlitzUI...

Graphics 199, 199, 16, 2
SetBuffer BackBuffer(  )
HidePointer

Include "blitzui.bb"

;Load fonts and mouse cursors
;and collect information
Initialise(  )

;Window
win001 = Window( 152, 47, 256, 213, "", "0", 0, 0, 0, 0 )

Repeat

	;Draw the GUI and update the mouse
	UpdateGUI(  )
	
	;Event Handling
	Select app\Event
		Case EVENT_WINDOW
			Select app\WindowEvent
			End Select
		Case EVENT_MENU
			Select app\MenuEvent
			End Select
		Case EVENT_GADGET
			Select app\GadgetEvent
			End Select
	End Select
	
	;Draw the mouse
	DrawMouse(  )
	
	;Reset all GUI events
	ResetEvents(  )

	Flip
	Cls

Until KeyHit( 1 ) Or app\Quit = True
;Free all images and controls created by BlitzUI
Destroy(  )
End

But I don't think thats what you want UNLESS you incorperate the GUI functions in your program...

Here is a some testing code I wrote a while back which uses API calls to create windows without title bar. It also uses ‘CreateRoundRectRgn’ to show the window with rounded corners…

Nah, that's just BlitzUI stuff.
I use that anyway (nice).

But I needed to really get rid of the titlebar.

Any way, sorry, I've been away - I should have said before I went that the solution can be found in another thread: "black out background at any rez".
