Hi friends,
Dialog box of one program is partially accessible to NVDA. I'm trying to fix this.

This dialog contains the following elements:
1. window title;
2. static text label;
3. checkbox with text description;
4. button "OK".

The problem is that the static text label is not voiced by NVDA. Only 1, 3 and 4 elements are accessable.
The class of this window contains only two children: checkbox (3) and button (4).

If you could tell me please, how can I add another fake StaticText child to the class of this dialog?

Here is the my appModule code:

import appModuleHandler
import controlTypes
from NVDAObjects.IAccessible import StaticText, delphi

class DialogMessage(StaticText):
    role = controlTypes.ROLE_STATICTEXT

    def _get_name(self):
        return self.displayText


class ExtendedDialog(delphi.Form):
    role = controlTypes.ROLE_DIALOG

    # how to add DialogMessage child to ExtendedDialog?


class AppModule(appModuleHandler.AppModule):

    def chooseNVDAObjectOverlayClasses(self, obj, clsList):
        if obj.windowClassName == "TMessageForm" and obj.role==controlTypes.ROLE_PANE:
            clsList.insert(0, ExtendedDialog)

    def __init__(self, *args, **kwargs):
        super(AppModule, self).__init__(*args, **kwargs)


Please help me to understand this issue.
I'm very grateful for any tips.
Oleksandr
