Select full-screen resolution of Qt5 app without window manager

jeroen94704

When I run a Qt app build using Qt5 in a non-X Linux environment (in my case on a Raspberry Pi), how do I select which resolution the app runs at? If I do nothing, the app runs at full resolution, which is 1080p. But the app was developed for a lower resolution, and the layout gets messed up at such a high res.

How can I set it to something lower (800x600, in my case)?

Thanks in advance,

Jeroen

Hi jeroen, have you had any feedback outside this board ? or maybe solved it yourself ?

Hi einarmar,

I am no longer working on that project, and we never got around to fixing that. Thinking about it now, in the meantime I learned how to change the resolution for the Raspberry pi. If that is the platform you are working on, you can force a specific video-mode/resolution by adding the hdmi_group and hdmi_mode to the config.txt file on the SD card. I suspect that will make the Qt application switch to the lower resolution as well.

Hi Jeroen, thank you for this reponse.
I'm currently just working on getting Qt5 to run on an embedded i386 target.
I have been using the examples that Qt5 provides and I managed to change the size of the window in the code.
