Ok. This is what I have already done. Ok for elm and widgets. For the time being, I only used EFL. I will look at the Elementary project.

Re: [e-users] Adapt canvas content when the canvas is resized
Hello, Thank you for your response. However with the callback way, content of the canvas will not be resized automatically. When the canvas is resized (according to the TV resolution), I would like that its content be resized automatically. Is there a way in Evas/Evas-Core to intercept the content (pixels) of a canvas before it's send to the framebuffer (in order to apply an alpha to it) ?

[e-users] Adapt canvas content when the canvas is resized
Hello, Is there a way in Evas/Ecore to automatically adapt the canvas content (size of each Evas object, font size, ...) when the canvas is resized ? Does this feature is supported in Evas/Ecore ? How to achieve that? Typical use case: the user change the resolution of the screen.
