Hello Martin, Jeroen,
did this made it into bugzilla?
I've hit the same problem and Jeroens change to
FocusHandler.__compareTabOrder fixed it as described.
Regards.
Dietrich.

Hello Jeroen,
I am using Qx v 1.4.1. and I ran into a an issue around "tabbing"
through controls as this is implemented in FocusHandler.js. I do not
set the tabIndex explicitely on widgets and therefore the code falls
back to the position and eventually the Z-order.
The code marked by the comment "// Sort-Check #2: Top-Position"
doesn't always work for me because it checks on the top of widgets to
exactly match:
// Sort-Check #2: Top-Position
if (loc1.top != loc2.top) {
return loc1.top - loc2.top;
}
This is not always the case in my layout and I still would like the
behaviour of tabbing from left to right to controls. As an example of
such a layout the following "example" with a checkbox in front of a
control to implement optional behaviour for the value of the actual
control:
______________
X | some control |
---------------------
When in the control and pressing SHIFT + TAB I expect to end up with
a checkbox having focus but that is not the case.
I tested with a slight adjustment of the code in
FocusHandler.__compareTabOrder like this
// Sort-Check #2: Top-Position
if (loc1.top != loc2.top) {
// Fallback for slight layout issues, e.g. the top of two controls
// differs by a (few) pixel(s)
if ((loc2.bottom < loc1.top) || (loc2.top > loc1.bottom)) {
// loc2 does not have an overlap in vertical coordinates otherwise
// we fallback to the diff on "left"
return loc1.top - loc2.top;
}
}
Looking at an overlop in the vertical position of widgets rather than
an exact match.
My question is:
-What do you think of this idea?
I totally agree with you and the expected behavior. Additionally, you
suggested solution sounds like a good approach to tackle that problem.
-Is this something that could be adjusted/patched in future versions?
Sure, go ahead and open up a bug report at out bugzilla [1]. You can
put in your code as well which will help a lot including that feature.
If you are familiar with git and github, feel free to create a pull
request for that feature. :)
Thanks,
Martin
