Re: How to use XControls?

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...
