>>ASSERTION Good A
A call to xname moves the window so that the
coordinates of the upper-left outer corner of the window
are
.M x ,
.M y
relative to the origin of the parent window.
>>STRATEGY
Create test window with background of W_FG.
Set x and y.
Call xname.
Verify that window has moved on screen with checkarea().
>>CODE
Window	base;
struct	area	area;

	base = onewin();

	setarea(&area, 20, 50, OW_WIDTH, OW_HEIGHT);
	x = area.x;
	y = area.y;

		CHECK;
	else {
		report("Error in moving window");
		FAIL;
	}

	CHECKPASS(1);
>>ASSERTION Good A
When the window is moved
and the window is mapped
and the window is not obscured by non-children, then the current window
contents are not lost.
>>STRATEGY
Create window.
Draw pattern in window.
Move window without a size change.
Verify that window contents are unchanged.
>>CODE
XImage	*imp;

	(void) onewin();

	pattern(display, w);

	x = NEW_X;

	}

	CHECKPASS(1);
>>ASSERTION Good D 3
When the window is moved
and the window is mapped
and backing store is being maintained for the window, then the current window
contents are not lost.
>># Kieron reckoned a sibling assertion to this in XConfigureWindow
>># was D 3. I have no reason to doubt this! stuart.
>>ASSERTION Good A
When a call to xname
uncovers part of any window that was formerly obscured, then
either
.S Expose
events are generated or the contents are restored from backing store.
>>STRATEGY
Create windows.
Create second client to receive events on.
Call setforexpose() on unobscured window.
Create other windows to partially obscure this window.
Reconfigure window with xname, ensuring that first window is now unobscured.
Verify for correct expose or backing store behaviour with exposecheck().
>>CODE
Window	base;
Display	*client2;
struct	buildtree	*bt;
int 	i;

	base = defwin(display);

	 * parent window.

	CHECKPASS(1);
>>ASSERTION Good A
When the window
is a root window, then a call to xname has no effect.
>>STRATEGY
Call xname on root window.
Touch test only.
>>CODE

	w = DefaultRootWindow(display);

	XCALL;

	if (fail == 0)
		PASS;
>>ASSERTION Good A
When the override-redirect flag of the window is
.S False
and some
other client has selected
.S SubstructureRedirectMask
on the parent window, then a
.S ConfigureRequest
event is generated, and the window position is not changed.
>>STRATEGY
Create windows.
Set override-redirect to False.
Create second client.
Select SubstructureRedirectMask for second client on parent of window.
Set some parameters.
Call xname.
Verify that a ConfigureRequest event is generated.
Verify that window configuration has not changed on the screen.

	}

	CHECKPASS(3);

>>ASSERTION Good A
When the position actually changes, then a
.S ConfigureNotify
event is generated.
>>STRATEGY
Create windows.
Enable SubstructureNotify events.
Call xname such that the window configuration changes.
Verify that a ConfigureNotify event is generated.
Call xname again with the same parameters.
Verify that no ConfigureNotify event is generated.
