Tk Source Code

TIP 733 - states that quote "the canvas widget is not exposed as an accessible object except by name" - How would I make a self drawn Label with the canvas accessible? For instance I have made me a "SelectableLabel" and a "EditableLabel" and would like to include the feature of accessibility.

I would like to include this link here, for everyone that is interested in that topic and find themselves here on their path of research.

Thanks for your reply.
Maybe I need to wait for the documentation on that feature.
Sadly there is none here https://www.tcl-lang.org/man/tcl9.1/TkCmd/index.html
and nothing is linked in the TIP.

But I think I understand what you suggested.
The parameters can be "customized by the developer as needed."
-> So I could just copy and paste the parameters content of a lable into a canvas.

I was afraid the parameters won't be available at all.

The canvas is explicitly excluded from accessible support because no platform has an API that supports making graphic objects accessible. You can probably work around this by setting the value or name of the canvas to whatever object is selected; that is how HTML5 makes the canvas widget accessible, by activating attributes of the widget itself rather than its rendered objects. You may have to experiment.
