             Summary: Orca's flat review mode can not be used [EBZ#543949]
                 Key: ERT-708
                 URL: https://issues.jboss.org/browse/ERT-708
             Project: Eclipse Release Train
          Issue Type: Task
          Components: Platform
            Reporter: Friendly Jira Robot


Recently I reported on the orca list a problem where every time I
tried to use flat review mode, my machine was completely frozen.

The problem has been fixed but now I can not use the flat review mode. According to Joanie, the person who corrected the problem, the cause is due to a bug in the eclipse. 

I am copying the text of the email I received because I believe it
will give more details.

Hey again.

I have good news and bad news. The good news is that I have fixed the
desktop lockup, at least for me. The bad news is that until the Eclipse
developers fix their bug, flat review will not work in impacted windows.

Eclipse is giving an insane bounding box (x, y, width, height) for a
panel which seems to be the child of the scroll pane in that dialog. I
get, for example, (618552120, 32709, 618552176, 32709). I should be
getting things like (598, 353, 720, 328). In theory one should be able
to test this in Accerciser, but Eclipse seems to still have that bug
where it takes 15 or so seconds (followed by a DBus timeout to become
responsive). And that seems to make Accerciser very unhappy. At least on
my machine.

Because flat review is constructing a 2-dimensional collection of
objects based on their bounding boxes, we need accurate (not to mention
sane) bounding boxes.

So the way the Eclipse developers can test this is to grab the latest
Orca master and perform the steps to reproduce. This time the expected
result is that Orca should present the window via flat review and the
actual result is that it just presents the name of the window ("Eclipse
Platform Launcher"). To see why, look in your friendly debug.out. Here's
what I get for reading the current line:

vvvvv CONSUME ATSPI_KEY_PRESSED_EVENT: 'KP_Up' (80) vvvvv
[normal, non-concerning stuff goes here]
00:47:16 - INFO: Extents for [panel | ] are: (618552120, 32709,
618552176, 32709)
00:47:16 - INFO: [panel | ] seems to have bogus coordinates
[normal, non-concerning stuff goes here]
^^^^^ CONSUME ATSPI_KEY_PRESSED_EVENT: 'KP_Up' (80) ^^^^^

You can quickly find these strings by searching for "bogus coordinates"
and then looking at the previous line.
----------

The steps to reproduce this problem are:
1. Activate orca but you need to grab the latest from git.

2. Launch eclipse.

3. When eclipse ask for the workspace try to explore the screen using the flat review mode.


Expected result:
Orca should read the content of the screen according to the commands used.

Actual result:
Orca reads only Eclipse IDE Launcher.

Important: If you use an old version of orca, probably yourmachine will freeze.
