RE: Start to scripting Orca

Thanks a lot this will help a lot.
I have succeded in assigning a resource to the task by going to resource usage and adding it there, but it was more luck than skill. 
Regards, Willem

Hi all

Willem, here is step by step:

1. Open planner.
2. To add a task press the tasks toggle button.
3. go to the table where the tasks are by tabbing.
4. Press control + i (a new task will be created).
5. In the task table left and right arrow to fill up the task information
(name, weeks, start date, end date... Etc). You have to press spacebar on
the differents fields to edit.
6. To add a resource activate the resources toggle button.
7. go to resources table by tabbing.
8. Press control + i to insert a resource
9. Right and left arrow to fill the information spacebar on the fields.
10. To assign a task a resource go back to tasks toggle button
11. Go to the table where the taks are
12. On a task display the poppup menu by pressing shift + f10
13. Down arrow until "assign a resource"
14. Here is the problem....

A new dialog appears to select resources, by tabbing you arrives to a
splitPane  with a unknown role on it that represent the resources and ATSPI
can not obtain information. I think this is a custom component that needs to
implement ATK so a new bug has to be filed for planner. Perhaps I don't know
enough information to file this, Rich Can you file it?

Thanks

Regards,

Javier

Hi,
Thanks, it did help.
It would be very helpfull if you could go through the adding of a task,
resource, etc. with key strokes.  I am now stuck at assigning a resource
to the task. The other task things was text entry fields, but this one, I
suppose give a list of already entered resources. I do not get that list. I
have checked in the saved file and the one resource which I have added
before is there.
Thanks so far.
Regards, Willem

Hi to all

Willem you have to firstly activate whatever toggle button you want,
tasks, resources, etc Then to add and entry you have to go to the
toolbar by tabbing the application and look for a "insert task" button
so a new task is inserted before you press it.
Then you can go to the table showing the new task information, and press
spacebar over the columns you want to modify. In the toolbar also there's
another unlabeled toggle button that if you press shows a popup menu to

add,

remove or whatever action on the selected item.

Hope this clarify

Regards,

Javier.

Hi,
Thanks for the detailed answer
and the script.
I grabbed Orca from CVS.  The make install did not put the new
planner.py script into its place, but when copied there it worked. I
am still rather lost in the program though.  I think I have
successfully added a resource, but will first have to check if it is
actually added as a resource in the saved project file.  Planner uses
xml to store the data in, so it is easy to check. I cannot seem to get
to the text entry fields for entering tasks. Does the no focus message
mean that Orca is lost as well? Thanks again for all the trouble you
took so far. Regards, Willem

I have just now tried to use planner, a project management tool.  It
sounds like it should be usable with some scripting.


Yes.


The problem is that I am new to gnome and orca of course.  What is
happening is that the thing says "toggel button pressed" or not
pressed when arrowing up and down.


I see/hear this too. Visually there is a column of toggle buttons
with graphical images down the left side of the main planner window.
They have text below them:

Gantt Chart
Tasks
Resources
Resource Usage

Unfortunately that text is not currently available to Orca to read.

Now if I look at the component hierarchy with at-poke, I can see that
that panel on the left is filled with a load of fillers each
containing a toggle button and a label. This will be enough to allow
us to get to the text describing each toggle button.


Above the line, a description occurs according to the 7 key on the
numpad. As I understand it, one can now  write a script to
automaticly speak the description together with the status of the
button.


Unfortunately it's not going to be as simple as that. The person(s)
that wrote planner should have used a LABEL_FOR relationship to
associated the label with the toggle button. I've filed bug #337382
(http://bugzilla.gnome.org/show_bug.cgi?id=337382) against planner on
this.

Having said that, we can easily workaround this with an Orca script
for planner.


Is this correct and is there an example script which might already
handle this situation?


Not exactly, but there are one that would make a good starting point.
Evolution has similar code in it. For something like this, I would
start with that. More on this below.


  Can one copy an existing script to the name of a new application
to have orca call it when the new application is opened?


Yes. To do a proper job (i.e. so that others can take advantage of
this work),
one would need to create a new script in the .../orca/src/orca/scripts
directory
called planner.py   It could start off as a copy of one of the other

scripts

in
that directory. You would also need to modify the Makefile.am file in
that directory, to make sure that the new script name was added to
the orca_python_PYTHON definition. This means that it would
automatically get installed in a location where Python can find it.

So here's what needs to be done to get this to work. I'll create an
initial planner.py script with the following in it.

class Script(default.Script):

  def __init__(self, app):

      default.Script.__init__(self, app)

Note that the real planner.py will have a load of extra things in it
like the initial copyright message, plus comments, debug messages and
import lines, but in order to try to keep it simple, I'll leave that
out here.

Now what we are interested in is when the focus is on one of those
four toggle buttons. To do this from within the planner.py script, we
need to subclass the onFocus() method. When that method is called, we
check the hierarchy of the component that currently has focus to see
if it matches what we want. To find out what we want, I would have
previously run Planner with Orca and hit Insert-F7 when the focus was
at one of the toggle buttons in Planner. Doing that I determined that
the component hierarchy I needed to be looking for

is:


toggle button
filler
filler
panel
panel
filler
filler
frame
application

I only need to use enough of these to make it unique.

Also, if it's a focus event for planner but it isn't this kind, then
we just want to pass
it off to the parent class.

This gives the following code:

  def onFocus(self, event):

      rolesList = [rolenames.ROLE_TOGGLE_BUTTON, \
                   rolenames.ROLE_FILLER, \
                   rolenames.ROLE_FILLER, \
                   rolenames.ROLE_PANEL, \
                   rolenames.ROLE_PANEL]
      if util.isDesiredFocusedItem(event.source, rolesList):
          ... handle this focus event ...
          return

      default.Script.onFocus(self, event)


Now we need to fill in the ".. handle this focus event ..." part.

What we want to do is use the filler component that is the parent of
the toggle button that current has focus. It's other child will be
the label that describes this toggle button. We want to get a handle
to that, extract the label and speak it. Here's the code that does
that:

          filler = event.source.parent
          allLabels = atspi.findByRole(filler, rolenames.ROLE_LABEL)
          speech.speak(allLabels[0].name)
          return

We just use allLabels[0] because we know that there is only going to
be one label found.

I've checked in the full version of this script in CVS HEAD for Orca.
I've also attached it to this message. If you place this in the
installed location for your Orca scripts, then it should work for
you. Or just check out the very latest version of Orca from CVS HEAD
and configure, build and install it.

As you navigate Planner with Orca, I expect you to find other places
where it's not providing enough information. Hopefully we'll be able
to file bugs against Planner so that they properly fix up these
problems. We should also hopefully be able to provide script
workarounds to improve the usability as well.


ps. Where does user questions for orca go?


This is a great place to ask questions like this. The mailing list is
archived. We can now point people back to this email.
