[Lazarus] LCL not accessible for blind users

[Luciano de Souza]

Hello all,
LCL applications can't be used by blind users. It's a bad news for blind 
programmers, but specially for blind users. It's a severe restriction if 
we regard it can occurs in the workplace.
Recently, I heard about a blind girls who couldn't access a desktop 
application. The developer makes an application wich returns a database 
query in a picture not readable for screen readers. The company doesn't 
have patience to search for another occupation for her. The consequence 
is that she will probably laid off.
I don't know if the application was writen in Lazarus. It's an example 
on what can happen when applications were designed without 
accessibilities concerns. It seems to be a little bit dramatical, but 
being blind, I can make sure the consequences are usually so unsuitable.
And why is not LCL accessible? As I couldn't use it because the lack of 
accessibility, I don't know if this is the single problem. But as far as 
I could realize, the problem are the labels. If I have a label "name" 
and an editbox to fill up this information, label is not read. The 
labels of buttons and those used in dialog messages are not read as well.
I tried to understand why the screen readers don't read it. The answer, 
for Windows system, was:

Two conditions need to be respected in order to provide information for 
screen readers. When using labels and editboxes in combination, it's 
necessary to set the mnemonic of label to point to the editbox. If I am 
right, it was done to set the property "control" of labels.
Yes, it's important, but it's not sufficient. Screen readers query 
information by means of the windows event called wn_gettext. If LCL does 
not handle this event, it's not possible to provide information for 
screen readers.
So my ask is: does LCL handle this event?
I will do some tests in Linux to give you some feed back about 
accessibility.
