Help to obtain information in a plug-in module for Chrome browser

Héctor Javier Benítez Corredera

Hi, I have a small add-on with some improvements that I need in the Chrome browser.

But I have a small problem that I can not know how to do.

When we download something with Chrome creates a Role.ALERT in which we are informing us of the download status by message and when it ends creates another with the message that the download is finished we press F6 to go to the download bar.

Well I paste my Developer info for navigator object: it can that when translating the message something remains in Spanish that is my language:

Developer info for navigator object:
name: 'Download complete: winrar-x64-611en.exe. Press Shift+F6 to move to the download bar area'.
role: Role.ALERT
roleText: None
isFocusable: False
hasFocus: False

IAccessible2 role: ROLE_SYSTEM_ALERT

IAccessible2 attributes: 'explicit-name:true;class:View;'
IAccessible2 relations:

In my add-on module I have this:

    def event_NVDAObject_init(self, obj):
        if obj.role == getRole("ALERT"):
            if obj.IAccessibleObject.accName(obj.IAccessibleChildID).split()[0] == _("Download"):

Well what I want is to send to the braille line the message that the download is finished.

This message for deaf blind people is important to know when the download is finished because the braille line does not inform by default of this message.

Well with the above I only get the download status message and if I take everything out of the if and just leave:

    def event_NVDAObject_init(self, obj):

Well, sometimes I get the message back and sometimes I don't, testing with the same download every time.

The truth is that I am lost.

Can someone clear me doubts or do it in another way?

Thank you very much in advance.

Best regards.
