Hi Gian.
well, I also never worked out how to achieve with direct scripting calls,
what can
be done more specificly using menu/wizard style front end within frames
manager itself,
regarding grabbing text of only certain colors within the Frames Construct
from within a script.
so, what I ended up dooen to get around this in my work, was I started using
another function called
GetTextInRect ()
instead. and then carefully worked out the actual absolute screen Left,
top, right and bottom coordinates of that rectangle/frame, which of course
make up the first 4 parameters of the GetTextInRect function.
This is not actually quite as easy as it may sound, because when you put
your mouse on a line of text, and mark the top left, and bottom right hand
corners of the frame,
Jaws Makes some smart adjustments/tweaks to those coordinates, such that all
the pixels which make up the text, are properly included in the frame size,
no matter what their height/font size might be.
check out the positioning tab, in the Frames Properties, remembering though
that they have been taken relative to application window boarders, and not
to absolute screen boarders, which is all that Alt+delete out of the box,
reports.
usually though you can subtract 3 pixels each way, to arrive at an absolute
coordinate, seems to be about standard.
and so you have to insure manually that you replicate this, when you define
your absolute screen coordinates
e.g. ... ok this gets a bit complicated. and I don't know if you've got hsc
connected to this scratchLive aplication or not. but it is critical if you
wanna use GetTextInRect, that
you get these absolute screen coordinates accurate, such that they properly
encompass the text at that location correctly. In my testings here, I found
that
the leftHand Coordinate, could be left pretty much at the same absolute x
screen coordinate that alt+delete reports, when your jaws cursor is on the
first letter of the text of the relevant frame.
For the top coordinate though, I've found that often, subtracting about 7
pixels
from the alt+delete Y coordinate readOut at that same spot, would often
suffice for the top of the rectangle coordinate.
For the RightHand coordinate, after taking the jaws cursor to the far right
hand
letter, or position where letters can be written, you might add, about
8 pixels to this figure, before plugging it into the rightHand coord of
GetTextInRect.
and for the Bottom, I'd look at the height of the Frame, in the positioning
tab, and make a guestimate on that. because it can depend on how large the
font is, of the text your talking about, as to the necessary height. the
Frames manager,
as I say, makes intelligent judgements about that during the definition
process, so, the idea is to try and build your getTextInRect off that.
thus, if the frame height was, say, 13 pixels high, then you'd add 13 pixels
to your top coordinate, to arrive at your bottom edge coordinate.
Here's the fsdn take on GetTextInRect. I usually leave a 0 as the fifth
parameter, and as it points out, the IgnoreColor, if I don't know the
foreground or background color of my text.
Do you have the fsdn and are you familiar with searching it for some
admittedly terseish definitions of functions?
