Hi Don,
Playing with your XControls library.
If I split a window and drag the spliter can I trap the resize event?

Can I use Autosize.ew from the eu archives with XControls or any other
auto resizing tool?

Hi Greg,
Please tell me if I plit a window horizontally then split the top pane
vertically, how do I call geometry to look after things in the top
left pand when that pane is resized.
In the example below it resizes with the entire window but not if I
adjust the pane.

What am I doing wrong.
Thanks

constant MainWin = createEx( Window, "", 0, Default, Default, 786,
567, {WS_THICKFRAME, WS_SYSMENU, WS_MINIMIZEBOX, WS_MAXIMIZEBOX},
{WS_EX_DLGMODALFRAME} )

constant
hGMID = xControl( Geometry, "", MainWin, 0, 0, 0, 0, 0, 0 ),
paneTop = create( Window, "", MainWin, 0, 0, 0, 0,
{WS_CHILD,WS_VISIBLE,WS_CLIPSIBLINGS} ),
hsplit = xControl( HSplitter, "", MainWin, 0, 280, 0, 0, 0, hGMID ),
paneBottom = create( Window, "", MainWin, 0, 0, 0, 0,
{WS_CHILD,WS_VISIBLE,WS_CLIPSIBLINGS} )
manage( hGMID, paneTop, {0,0}, {0,0}, {1.0,0}, {hsplit,0} )
manage( hGMID, paneBottom, {0,0}, {hsplit,0}, {1.0,0}, {1.0,0} )

constant
vGMID = xControl( Geometry, "", paneTop, 0, 0, 0, 0, 0, 0 ),
paneLeft = create( Window, "", paneTop, 0, 0, 0, 0,
{WS_CHILD,WS_VISIBLE,WS_CLIPSIBLINGS} ),
vsplit = xControl( VSplitter, "", paneTop, 600, 0, 0, 0, 0, vGMID ),
paneRight = create( Window, "", paneTop, 0, 0, 0, 0,
{WS_CHILD,WS_VISIBLE,WS_CLIPSIBLINGS} )
manage( vGMID, paneLeft, {0,0}, {0,0}, {vsplit,0}, {1.0,0} )
--manage( vGMID, paneLeft, {0,0}, {0,0}, {0,0.75}, {1.0,0} )
manage( vGMID, paneRight, {vsplit,5}, {0,0}, {1.0,0}, {1.0,0} )

manage_now( hGMID )
manage_now( vGMID )

integer KeyGroupGrid KeyGroupGrid = EGW_CreateGrid( paneLeft, 4, 52,
592, 188, 1 )

manage( hGMID, KeyGroupGrid, {0,4}, {0,24}, {0.50,4}, {0.80,0} )

No Autosize does not work with XControls. Autosize seems to get it
info from the main window not the window in an XContol pane.

Still can't figure how to get geometry to size the elements in the
windows that have been created with vsplt or hsplit.

BTW love Autosize have been using it for a while. Its great.

Tony

Hmmm, well...

global procedure attach_control(object id, object placement)
	sequence winSize, objPlacement
	integer parentwin

	--If id is a sequence, then recurse.
	if sequence(id) then
		for a = 1 to length(id) do
			attach_control(id[a], placement)
		end for
		return
	end if

	--Find the window this control is in, if none then fail.
	parentwin = findParentWindow(id)

Hmmm, I'm not too familiar with Xcontrols, although I've checked out
the demos and it looks impressive.

The way that Autosize figures out which resizes it should be trapping
is just inside the
attach_control() procedure:

--Find the window this control is in, if none then fail.
	parentwin = findParentWindow(id)

So, technically, it's win32lib's fault. 
If there's a way to get the parent (not necissarily a window) of the
control, then that'd be a simple drop-in replacement of that line,
that would work with Xcontrols, with an added bonus of making Autosize
automatically heirarchical (So that you could use Autosize to manage
controls relative to a 'group' or a 'tab control'.)

> Hope this helps you to help me, which in turn may help you. (wow)

Sounds like it could be helpful to me, cause it'd make Autosize even better.
Should make things fine for Xcontrols, as long as the custom panes
still generate onResize events.

I've been working on fixing Autosize to handle this properly... All
you have to do is change 'findParentWindow' to 'findParent', and
change the error check below it to check for '<= 0', and it should
work.

I made a quick demo for this, and encountered a problem for tab
controls though...

without warning
include win32Lib.ew
include autosize.ew --(You have to make the changes to autosize described above)

constant win = create( Window, "Demo 5 - Hierarchical Autosizing", 0,
Default, Default, 0, 0, 0 )
setClientRect(win, 400,400)
constant tab = create( TabControl, "", win, 10,10, 180,180, 0),
			tab1 = create( TabItem, "Tab 1", tab, 0,0,0,0,0),
				b1 = create( Button, "B", tab1, 8, 20, 24, 24, 0),
				b2 = create( Button, "B", tab1, 150, 150, 24, 24, 0)

constant group = create( Group, "Group 1", win, 210, 210, 180, 180, 0),
				b3 = create( Button, "B", group, 8, 15, 24, 24, 0),
				b4 = create( Button, "B", group, 150, 150, 24, 24, 0)

attach_control( tab, {TL, MM} )
attach_control( b1, TL ) 
attach_control( b2, BR )
attach_control( group, {MM, BR} )
attach_control( b3, TL ) 
attach_control( b4, BR )

WinMain( win,Normal )

The buttons in the group move correctly, but the buttons in the tab do
not. The TabControl picks up the resize events, but it seems the
TabItems do not. The parent of the button is the TabItem, not the
TabControl. I could work around this by testing if the parent is a
TabItem, and if so getting *its* parent, but it seems like a bit of a
kludge. Any suggestions as to making it work for things in Tabs? (and,
presumably, any Xcontrols that are like this)

That is a general solution, I might make this an overloaded
function... it's not quite as elegant as the way it's currently done,
so I wouldn't make it the norm.


Thanks for your suggestions...

Yes, I do see the smiley, but in any case, please RTM. 

  findParentWindow(id)  --> Locates a Window type control that the id is in.
  findTopLevelWindow(id)  --> Locates topmost Window control that the id is in.
  findParent(id) --> Locates the owning control for id.

There may also be some special processing involved with TabItems. When you
call findParent() on an id that is in a TabItem, Win32Lib returns the
TabItem's id, but Microsoft does regard the TabItem as a real control. So
you can't simply resize a TabItem, instead you need to resize the TabControl
that the TabItem belongs to.

So if findParent() returns the id of a TabItem, you need to do an additional
findParent() to get the TabControl's id.

   par = findParent(id)
   if getControlInfo(par, CONTROLINFO_type) = TabItem then
      par = findParent(par)
   end if
   setRect( par, newLeft, newTop, newWidth, newHeight, w32True )

Hope this helps.

I think that Win32lib should be smart enough to know that if you try to
resize a TabItem that the owning TabControl is what really should be resized.
I'll think about making this change.

That sounds fine to me.
