CK,

What is it you're trying to accomplish?  If you comment out the manage()
call for List7 then it appears in the correct spot in the tab item.

Are you trying to get List7 to shrink/expand with changes to the main
window's size?

CK,

Yep, you're right!  I do remember running into this problem in the past.
In my case, I just made the tab control a static size and let the rest
of the controls on the window change size/position.  

Maybe Don can take a look at this...lemme see if I can get him...Don???
Don???? Hello?  Hmmmm...I'll leave a message:

Don, in addition to CK, I would like the ability to change the size
of child controls in a tab control.  Thanks.

Sorry...too much coffee today.

Here's a version that ALMOST works perfectly. As you can see, even though
I'm supposedly splitting the area 50/50 for each list box, the one on top
is shorter than the one on bottom.

I think xControls should manage all this automagically. :)

include Win32Lib.ew
include xcontrols.ew

integer top, htop
	top = 25
	htop = floor(top/4)
	
constant
	-- windows and controls
	Window1 = createEx( Window, "Window1", 0, Default, Default, 400, 300, 0, 0 ),
TabControl2 = createEx( TabControl, "TabControl2", Window1, 24, 8, 300, 232, 0,
0 ),
	TabItem3 = createEx( TabItem, "TabItem3", TabControl2, 0, 0, 0, 0, 0, 0 ),
	TabItem4 = createEx( TabItem, "TabItem4", TabControl2, 0, 0, 0, 0, 0, 0 ),
List7 = create( List, "List7", TabItem4, 40, 44, 148, 120, LBS_NOINTEGRALHEIGHT
),
List8 = create( List, "List7", TabItem4, 40, 44, 148, 120, LBS_NOINTEGRALHEIGHT
),
	TabItem5 = createEx( TabItem, "TabItem5", TabControl2, 0, 0, 0, 0, 0, 0 ),
	TabItem6 = createEx( TabItem, "TabItem6", TabControl2, 0, 0, 0, 0, 0, 0 ),

	-- xcontrols	
	xControl_Window1 = xControl( Geometry, "", Window1, 0, 0, 0, 0, 0, 0 ),
	xControl_TabControl2 = xControl( Geometry, "", TabControl2, 0, 0, 0, 0, 0, 0 )

	manage(xControl_Window1,TabControl2,{0,5},{0,5},{1,-5},{1,-5})
	manage(xControl_TabControl2,List7,{0,5},{0,top},{0.5,-5},{0.5,-htop+5})
	manage(xControl_TabControl2,List8,{0,5},{.5,htop-5},{0.5,-5},{1,-5})

	setFocus(TabItem4)

WinMain( Window1,Normal )

First draft.  If this works good ill patch an update through.
Replace procedure GM_Manager with this:

[eucode]
-- procedure: GM_Manager [win32 callback loop]
-------------------------------------
procedure GM_Manager( integer parentID, integer event, sequence params )
	sequence newPos, attribs, classType, Rect
    sequence Offset
	integer width, height
	atom Void
    atom TRect

    Offset = {0,0}
    Rect = getClientRect( parentID )
	classType = getControlInfo( parentID, {CONTROLINFO_class} )
    if classType[1] != 0 then
        if classType[1] = 11 then -- tab control
            TRect = allocate( 16 )
            poke4( TRect, Rect[1..4] )
            Void = sendMessage( parentID, TCM_ADJUSTRECT, 0, TRect )
            Rect = peek4u( {TRect,4} ) & Rect[5..6]
            free( TRect )
            Offset = Rect[1..2]
            Rect[6] -= Rect[2]
            Rect[4] -= Rect[2]
            Rect[5] -= Rect[1]
            Rect[3] -= Rect[1]
            Rect[1..2] = {0,0}
        end if
    end if
	params[2..3] = Rect[3..4]

	if Rect[2] != 0 then
		params[3] = Rect[6]
	end if

	if onResize[parentID] != -1 then
		call_proc( onResize[parentID], params )
	end if

	if params[1] != SIZE_MINIMIZED then
		newPos = repeat( 0, 6 )
		if length(IDsManaged[parentID]) > 0 then
			w32Proc( gmLockWindowUpdate, {parentID} )

			for index = 1 to length(IDsManaged[parentID]) do
				attribs = IDsManaged[parentID][index]
				for index2 = 1 to 4 do
					if attribs[index2+1][1] <= 1
then newPos[index2] = floor(
params[and_bits(or_bits(xor_bits(index2,1),2),3)] * attribs[index2+1][1] )
else newPos[index2] = PrevPlaced[ attribs[index2+1][1] ][
index2+2-(index2>2)*4 ]
					end if
					newPos[index2] += attribs[index2+1][2]
					PrevPlaced[ attribs[1] ][index2] = newPos[index2]
				end for
				newPos[5] = newPos[3] - newPos[1]
				newPos[6] = newPos[4] - newPos[2]

setRect( attribs[1], newPos[1]+Offset[1], newPos[2]+Offset[2], newPos[5],
newPos[6], True )
				classType = getControlInfo( attribs[1], {CONTROLINFO_class} )
				if classType[1] = 2 then -- 2 = COMBO
					Void = sendMessage( attribs[1], CB_SETDROPPEDWIDTH, newPos[5], 0 )
				else
				end if
			end for
			w32Proc( gmLockWindowUpdate, {0} )
		end if
	end if
end procedure
[/eucode]

And you can test it with this:

[eucode]
include Win32Lib.ew
include xcontrols.ew

constant
	-- windows and controls
	Window1 = createEx( Window, "Window1", 0, Default, Default, 400, 300, 0, 0 ),
TabControl2 = createEx( TabControl, "TabControl2", Window1, 24, 8, 300, 232, 0,
0 ),
	TabItem3 = createEx( TabItem, "TabItem3", TabControl2, 0, 0, 0, 0, 0, 0 ),
	TabItem4 = createEx( TabItem, "TabItem4", TabControl2, 0, 0, 0, 0, 0, 0 ),
List7 = create( List, "List7", TabItem4, 40, 44, 148, 120, LBS_NOINTEGRALHEIGHT
),
List8 = create( List, "List7", TabItem4, 40, 44, 148, 120, LBS_NOINTEGRALHEIGHT
),
	TabItem5 = createEx( TabItem, "TabItem5", TabControl2, 0, 0, 0, 0, 0, 0 ),
	TabItem6 = createEx( TabItem, "TabItem6", TabControl2, 0, 0, 0, 0, 0, 0 ),

	-- xcontrols	
	xControl_Window1 = xControl( Geometry, "", Window1, 0, 0, 0, 0, 0, 0 ),
	xControl_TabControl2 = xControl( Geometry, "", TabControl2, 0, 0, 0, 0, 0, 0 )

	manage(xControl_Window1,TabControl2,{0,5},{0,5},{1,-5},{1,-5})
	manage(xControl_TabControl2,List7,{0,5},{0,5},{1,-5},{0.5,-5})
	manage(xControl_TabControl2,List8,{0,5},{0.5,5},{1,-5},{1,-5})

	setFocus(TabItem4)

WinMain( Window1,Normal )
[/eucode]

Don,

Just curious...would this work with group controls as well?

Nods, I looked and Group controls were also broken.  They work now also.
I posted the fixes up to RDS along with support for icon files for the Menu
library.
