[Feature Request] Implement Background Widget so the Slide transition only slides the other widgets but not the background.

[Plaramee]

Pretty advanced feature I'm requesting here, but would it be possible to have a Background Widget so it can be excluded from the Slide screen transitions? This way, if we have an application with multiple screens that all have the same background image, we could have a Slide transition that leaves the background intact but only slides the widgets that are over the background.

I have no idea if this is even possible with the current transition implementation of Touch GFX, but it would surely make an awesome feature!

Thank you,

Hi @Philippe Laramée​,

It's not possible out of the box, but it's an interesting idea. It would perform worse since you cannot simply create a snapshot of the framebuffer and move that, at some rate, using DMA2D. You would be moving drawables (And not a finished, rendered frame) that may have alpha settings which must be blended with the background.

Best regards,

Martin

You could do something clever using the swipe container instead. Depending on how many "views" or pages share this common background. Doing it in a swipe container would incur additional memory consumption but might give you what you need in the short term.

Totally agree here. It'd be an incredibly useful feature.
