with at-spi1, we get the appnames, just as list of string, in v2 its dbus.String !

Just copy this code block in a file, say test.py and run 'python test.py' couple of times:

from ldtp import *

launchapp('gedit')

waittillguiexist('*-gedit')

settextvalue('*-gedit', 'txt1', 'Hello World')

print gettextvalue('*-gedit', 'txt1')

selectmenuitem('*-gedit', 'mnuFile;mnuQuit')

waittillguiexist('Question')

click('Question', 'Close without Saving')

Result:

After comment #2, the only option left to me is, kill the ldtp instance and then re-run the test !

(In reply to comment #1)

Output with v1

>>> getapplist()
['gnome-session', 'metacity', 'gnome-panel', 'nautilus', 'gnome-screensaver', 'gpk-update-icon', 'gnome-settings-daemon', 'bluetooth-applet', 'nm-applet', 'tracker-status-icon', 'Do', 'applet.py', 'gnome-volume-control-applet', 'gnome-power-manager', 'vino-server', 'evolution-alarm-notify', 'polkit-gnome-authentication-agent-1', 'gnome-terminal', 'gnome-terminal']

Another issue:

I can kill the instance of ldtp, by pressing control+c, if I start it manually as ldtp from terminal with at-spi1, but with at-spi2, it just hangs, need to debug further !

All of the above and following testing are based on openSUSE 11.3 (64-bit) and at-spi2 built by Stephen for my testing and its available here - http://download.opensuse.org/repositories/Mono:/UIA:/ldtp2/openSUSE_11.3/

from at-spi1 openSUSE11.3 64-bit

>>> getwindowlist()
['frmBottomExpandedEdgePanel', 'frmTopExpandedEdgePanel', 'frmx-nautilus-desktop', 'frmadministrator@w1-hutlab080:~', 'frmpastebin.engprivatepastebin-collaborativedebuggingtool-MozillaFirefox']

from at-spi2 openSUSE11.3 64-bit

>>> getwindowlist()
['frmadministrator@w1-hutlab081:~', u'frmBug31012\u2013CombinedbugreportfromLDTPv2-MozillaFirefox', 'frmXChat:nags@GimpNet/#atspidbus(+tn)']

Note the difference !?!

gnome-panel, nautilus are not accessible, atleast not visible just on the start of the system. I even tried launching nautilus, but it doesn't show up in getwindowlist() output !

The following two steps, just hanged the execution

>>> launchapp('nautilus')

Need to kill ldtp process

(In reply to comment #2)

Things seem to work fine, if I just run the script directly, without starting the ldtp instance manually !

There are 2 ways to run the test:

* start 'ldtp' binary manually for debugging purpose from one terminal with export LDTP_DEBUG=2 and then from another terminal, run 'python test.py'
* Just run 'python test.py', as this internally start ldtp instance, by forking 'python -c "import ldtpd;ldtpd.main()"'

Not sure, whey the number keeps changing !

These warning messages can be avoided ?

** (ldtp:1947): WARNING **: AT-SPI: Got error: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

This happened when I stopped the test in between.

Not sure what these error messages are:

        try:
            texti = obj.queryEditableText()
        except NotImplementedError:
            raise LdtpServerException('Text cannot be entered into object.')

        return int(texti.setTextContents(data.encode('utf-8')))

setTextContents fails, but insertText works !

Created attachment 42424 [details]
at-spi1 combo box have text entry

at-spi1 combo box have text entry

Created attachment 42425 [details]
at-spi2 combo box doesn't have text entry

at-spi2 combo box doesn't have text entry

The warnings should have been exceptions (at-spi2-atk thinks that the accessibles aren't there anymore), so they will show up as exceptions now.

setTextContents is fixed.

Querying for source_name should work now.

As far as the combo box child issue goes, I haven't been able to reproduce it per se--the combo box seems to show up as having no children even with AT-SPI1.  It is possible that I'm not following the right procedure to reproduce it.  I don't see any code in gail to send a children-changed event when an entry is added or removed from a combo box, so it may be related to that.  As a work-around for these kinds of issues, I've added a function called setcacheMask into AT-SPI/pyatspi.  If you put something like this near the beginning of your script, then I wonder if the problem will disappear:

desktop = pyatspi.Registry.getDesktop(0)
desktop.setCacheMask(pyatspi.cache(pyatspi.cache.ALL ^ pyatspi.cache.CHILDREN))

If that gets things to work, then we really should fix GAIL; AT-SPI2 will cache an object's children, parent, name, description, and states by default to reduce the number of round-trip calls that it needs to make, since they are more expensive with DBus than with ORBit.  As a result, it is sensitive to the lack of events in a way that AT-SPI-CORBA was not.

I'm not sure why you'd still get tracebacks calling setTextContents with pyatspi 1.91.6.  However, I needed to refactor EditableText anyhow since the existing code did not allow Text functions (ie, getText() to be called from the interface returned by queryEditableText.  So perhaps the change I just pushed will fix the issue.

What versions of gedit and gtk+ are you using that show the text child in AT-SPI1?  I am not seeing a text child in natty with either AT-SPI1 or AT-SPI2, and the script at http://pastebin.com/8uz5W5fB fails to find the child with both AT-SPI1, and AT-SPI2.  Looking at the sources of gedit 2.30.4 and gtk+ 2.24.1 (the versions I have on natty), I can't see how the text child could ever be exposed correctly.

gailcombobox.c, used for a GtkComboBox, exposes 1 or 2 children: a MENU child and an additional TEXT child if the has-entry property is set.

The combo boxes in the gedit find dialog are GeditHistoryEntry dialogues.  GeditHistoryEntry as of v2.30.4 was based on GtkComboBoxEntry.  GtkComboBoxEntry was based on GtkComboBox but did not set has_entry.  Rather, it created its own entry child.  GAIL does not appear to have a separate class for GtkComboBoxEntry, so it will use the logic for GtkComboBox, overriding the normal logic for determining the number of children and thus ignoring the entry that GtkComboBoxEntry adds.  Note that GtkComboBoxEntry was deprecated in GTK+ 2.24 and is removed in GTK+ 3, so later versions of gedit do not use it.

So, if you are seeing a text child with these versions of gedit and gtk+, then I am confused...
