Anyone know how to set a window's frame thickness?

[kdmoyers]

I need to reduce the screen space taken up by a certain 3rd party program, and was hoping to do this by reducing the thickness of the frame surrounding the window, perhaps reducing it all the way to zero.

I need to preserve the caption of the window, so the user can access the system menu and grab the caption to slide the window around. 

I was hoping to find some clever "SetWindowLongA" dll call, but so far no luck.

Anyone know a trick for this?

TIA,

You can get the height of a window title bar using WinMetrics option 4. WinMetrics options 7 & 8 can GET the width/height of dialog box frames.

I perused the list of window styles and didn't find anything useful: http://msdn.microsoft.com/en-us/library/windows/desktop/ms632600(v=vs.85).aspx and http://msdn.microsoft.com/en-us/library/windows/desktop/ff700543(v=vs.85).aspx.

As I understand it the window border size is a global setting in windows: http://www.sevenforums.com/tutorials/6283-borders-changing-width-suite-your-needs.html.

Take a look at the SysParamInfo option 6: SetBorder - Sets the border multiplier factor that determines the width of a window's sizing border.

Apparently you can also set this value in the registry:

Any one else?

yeah, I was afraid of that.  Seems like removing the caption (top bar) of a window is a cinch, but getting rid of the surrounding border is a whole nother thing...  rats.

Don't know if you can get the desired frame you want by playing around with various style values in this, but here it is anyway...

Code  winbatch Select Expand

#DefineFunction WinStyleTest(title);Use at own risk.. some styles may stop your window working properly

;see http://msdn.microsoft.com/en-us/library/windows/desktop/ms632600(v=vs.85).aspx
	GWL_STYLE = -16
	GWL_EXSTYLE = -20
	WS_OVERLAPPED = 0;Same as WS_TILED   You could almost think of this as the generic default window for most applications.. It has a Title bar and a Border 
	WS_BORDER = 8388608
	WS_CAPTION = 12582912
	WS_DLGFRAME = 4194304
	WS_SIZEBOX = 262144;Same as WS_THICKFRAME
	WS_HSCROLL = 1048576
	WS_VSCROLL = 2097152

	WS_EX_CLIENTEDGE = 512
	WS_EX_DLGMODALFRAME = 1
	WS_EX_STATICEDGE = 131072
	WS_EX_TOOLWINDOW = 128
	WS_EX_WINDOWEDGE = 256


	hWnd=DllHwnd(title)
	DllUSER32=strcat(DirWindows(1),"USER32.DLL")
	Style=DllCall(DllUSER32,long:"GetWindowLongA",long:hWnd,long:GWL_STYLE)
	StyleEx=DllCall(DllUSER32,long:"GetWindowLongA",long:hWnd,long:GWL_EXSTYLE)

	Message("Current Styles: Style and StyleEx",Style:@CR:StyleEx)

	Style = Style ^ WS_DLGFRAME
   StyleEx=StyleEx ^ WS_EX_TOOLWINDOW

   DllCall(DllUSER32,long:"SetWindowLongA",long:hWnd,long:GWL_STYLE,long:Style)

   DllCall(DllUSER32,long:"SetWindowLongA",long:hWnd,long:GWL_EXSTYLE,long:StyleEx)

DllCall(DllUSER32,long:"SetWindowPos", long:hWnd, long:0, long:0, long:0, long:0, long:0, long:32|2|1);Redraw
#EndFunction


;WinStyleTest("Untitled - Notepad")
WinStyleTest("Calculator")
