Pathbutton doesn't expose text to accessibility aids

[Matthew Paul Thomas]

Binary package hint: software-center

1. In Ubuntu Software Center, navigate to "Get Software" > "Games" > "Arcade" > "Bomber".
2. In Accerciser, navigate to software-center > Ubuntu Software Centre > (blank) > (split pane) > (page tab list) > (first page tab) > (panel) > (filler) > (filler) > (first element).

What happens: The element has Name "" and Children "0".

What should happen:
* The element has Name "You are here:" and Children "4".
* There are four child elements with Role "push button": "Get Software", "Games", Arcade", and "Bomber".

Willie Walker suggests these two resources for helping with this:

I commited some fixes for this into bzr, but it appears for a proper fix we need to implement "atk.Component" in Pathbar and PathPart to make it really work.

We have a branch for this now that adds the following new strings:

+#: ../softwarecenter/view/widgets/backforward.py:60
+msgid "History Navigation"
+msgstr ""
+
+#: ../softwarecenter/view/widgets/backforward.py:61
+msgid ""
+"Click either the back or forwards buttons to navigate your viewed pages "
+"history"
+msgstr ""
+
+#: ../softwarecenter/view/widgets/backforward.py:72
+#: ../softwarecenter/view/widgets/backforward.py:86
+msgid "Back Button"
+msgstr ""
+
+#: ../softwarecenter/view/widgets/backforward.py:73
+#: ../softwarecenter/view/widgets/backforward.py:87
+msgid "Click here to navigated backwards through your viewed pages history"
+msgstr ""
+
+#: ../softwarecenter/view/widgets/backforward.py:78
+#: ../softwarecenter/view/widgets/backforward.py:92
+msgid "Forward Button"
+msgstr ""

+#: ../softwarecenter/view/widgets/backforward.py:79
+#: ../softwarecenter/view/widgets/backforward.py:93
+msgid "Click here to navigated forwards through your viewed pages history"
+msgstr ""
+

+msgid "You are here:"
+msgstr ""

+#, python-format
+msgid "Click here to navigate to the %s page"
+msgstr ""

The lp:~mmcg069/software-center/pathbar-atk contains fixes for this.

[Michael Vogt (mvo)]

It works well in accerciser and shows the right releations.

[Matthew Paul Thomas (mpt)]

In this branch, but not in trunk r683, the Back and Forward buttons don't work: they're always insensitive.

Because of that bug, I can't test whether the description for the Back and Forward buttons work. I don't think it's useful to have a description for the buttons as a pair; a description just for each button should be fine.

The descriptions for the individual pathbutton elements work.

"Click here to navigated" is not correct grammar, and I doubt that it's appropriate for Orca descriptions to include "Click here to" anyway. I suggest changing each occurrence of "Click here to navigated" to "Navigates", e.g. "Navigates to the %s page."

[Matthew McGowan (mmcg069)]

Hi mpt,

backforward buttons seem fine here. How did you test? As for the atk strings i can modify easily.
