<![CDATA[Support QT/E ARGB1555 Framebuffer?]]>Hello.
I porting QT/E on my ARM core device.
My device support only ARGB1555 format framebuffer.

I know that QT/E 4.x not support ARGB1555 format framebuffer, is that right?
When I port and run some example on my board, every pixels not visible(transparency).

So, I use DirectFB back-end with QT/E v4, then example working well !
But I don't want using DirectFB because size and memory issue(my board has small memory).

So... I wondering know that QT/E v5.x support ARGB1555 format framebuffer or not.

How can I use QT/E v4 or v5 on my board ARGB1555 format framebuffer without DirectFB?

Someone give me some way.

Have a good day.
Thank you.

Thank you for reply.

As you said, we shall optimize Qt and DFB.

Thank you.

AFAIK, there's no particular support for that format in Qt 5. Anyway, since you have DirectFB working well, why not optimize Qt and your software to use less resources ? What is the current memory usage that DirectFB implies that makes it unsuitable ? What are your memory constraints ?
