Re: [orca-list] Web development with Orca

[Peter Vágner <pvagner pvagner tk>]

Hello,


Orca has no notion of HTML elements or other controls such as GTK 
widgets it can only look at accessible objects corresponding with those 
elements. Retrieving location info is doable I think but may not be 
implemented for all apps. I even don't know if orca is currently using 
this somewhere.

I only wanted to say my latest experience on this matter. I have always 
assumed location info, object coordinates, size and all that stuff is 
only marginally usefull to me as a screen reader user.

However a few weeks ago I was asked to create a short power point 
presentation at my work place. I have used Microsoft Powerpoint as 
packaged with Office 2016 for Office 365 and NVDA 2018.1 to do that 
task. And I was surprised how awesome the experience was. NVDA is using 
location info about the objects in powerpoint to give a hint if objects 
are overlapping, how far from the edge they are positioned. When 
combined that with the size information that is presented in the object 
properties I was even able to add some screen shots into my presentation 
and the overal look was very satisfactory.

So perhaps sometime in the future we might have similar features on 
linux as well. However it's important to note orca is only presenting 
this info and there might be issues elsewhere too.



Greetings


Peter
