Oops. I should have specified that in the case of the lower case i and w
I mentioned it is only the width that will vary. The height will always
be 8 but you need some room for borders of controls, or, for example, in
the case of buttons, just how you want them to look.

For what it's worth, dialog units are used in these dialogs. Dialog
units scale to the resolution and aspect ratio of the current display.
So everything will be the same relative size regardless of the resolution.
Dialog units are not as precise as pixels but they're good enough unless
you want your window to be a work of art. They work on an average of 4
units wide and 8 units high per character. And be it that it's an
average, a lower case i will be less than a w. But it works out pretty
good on average for location, sizing, and spacing.
You may also want to offset things to get the best alignment. For
example, in the case of a static text label next to an edit box the edit
box will be a little taller due to the border. So you could make the
static text 10 high, the edit box 12, and offset them so that the static
text lines up with the text entered into the edit box. Check it with the
mouse to make sure it's right.
Disclaimer: It's been ages since I wrote a Window-Eyes script dialog.
But I use this method in standard programming. So Aaron can slash my
tires if necessary.

I have an idea, for an enhancement when constructing XML dialogs. That
is, if it is possible... :)
When defining an element, you can set the hight, width and the X and Y
positions. Yet, for a blind person, with no sighted assistance, this is
really quite a hit-and-miss job. OK, we got the AUTO feature for Hight
and Width, and to play safe as can be, that might be the one way to go.
But then we have the actual positioning of the element. Had all screens
looked the same, and all fonts been the same size, we could have gone by
screenpoints. But even that is a hit and miss. So, AISquared has
provided the chance to position our stuff on TOP, at BOTTOM, or align it
in the CENTER or near the LEFT and RIGHT edge.
I just wondered, if it would have been possible to implement a chance
for me, to define the size of the element percent-wise, in both the X
and Y direction. I could then have decided that my button should sit in
the upper left corner, and take up say 10 X-percent, and 5 Y-Percent. My
Next element, an edit box, I could have defined to sit 15 percent down
the X-line, and cover the next 3 X-percent. that is, it would start at
X15, and end at X17 percent. And it would stretch from Y20 to Y49
percent.
Hope the above gave a bit of meaning. The Dialog could then - all in the
background - do all the percent calculation, based on the actual size of
the dialog on the current computer, screen and under the currently
conditions that affects the dialog's physical size. It would have been a
bit easier, for me as a blind person to have things correctly positioned
and sized, did I have some tangible and reliable numbers to operate with.
In other words, could we have a feature to set the actual upper-left and
lower-right corners of an element, and also the starting position for
it, all based on percents of the total dialog size?
Anyone have some input on this?
Thanks,
