Those were added on the old "just for automatic testing" times. That was somewhat silly on that moment. Now is just silly (ie: having the stage returning as default name "Stage"). The real description should be set by the app, or provided by the context of a specific actor feature (like the tooltip on StWidget). The current information provided by the default description can be mostly obtained from the ATK_ROLE, and the indirect debugging advantage of having always a meaningful description is just not enough to justify them, and you can solve that by proper debug logging.

|

|
|

|
|
* #CallyClone implements the required ATK interfaces of #ClutterClone
|
|
*
|
|

/* Design rationale for CallyClone:
|
|
*
|
|
* In the old times, it was just ClutterCloneTexture. So, from a a11y POV
|
|
* CallyCloneTexture was just another image, like ClutterTexture, and if
|
|
* it was a clone was irrevelant. So on cally-0.8, CallyCloneTexture
|
|
* expose a object with role ATK_ROLE_IMAGE. But now, ClutterClone is more
|
|
* general. You can clone any object, including groups, and made things
|
|
* like have one text entry, and a clone with different properties in the
|
|
* same window, updated both at once.
|
|
*
|
|
* The question is if the idea is have a ClutterClone as a "first-class"
|
|
* citizen inside the stage hierarchy (full clone), or it is just supposed
|
|
* to be a mirror image of the original object.
|
|
*
|
|
* In the case of the a11y POV this would mean that if the text changes on
|
|
* the source, the clone should emit as well the text-changing signals.
|
|
*
|
|
* As ClutterClone smartly just paint the same object with different
|
|
* parameters, this would mean that it should be the cally object the one
|
|
* that should replicate the source clutter hierarchy to do that,
|
|
* something that just sound crazy.
|
|
*
|
|
* Taking into account that:
|
|
*
|
|
* - ClutterClone doesn't re-emit mirrored signals from the source
|
|
* I think that likely the answer would be "yes, it is just a
|
|
* mirrored image, not a real full clone".
|
|
*
|
|
* - You can't interact directly with the clone (ie: focus, and so on).
|
|
* Its basic usage (right now) is clone textures.
|
|
*
|
|
* Any other solution could be overwhelming.
|
|
*
|
|
* I think that the final solution would be that ClutterClone from the
|
|
* a11y POV should still be managed as a image (with the proper properties,
|
|
* position, size, etc.).
