I looked in CodyCam's code and it seems to already be using the layout API, or did I accidentally miss a section of code?

Hmm, this is odd. I can't reproduce GUI problems (overlapping) in vmware with 24pt. font but it looks messed up on real hw with HiDPI. The same with #13164 and #13166. The only difference is resolution.

comment:3 by CodeforEvolution, 6 years ago

In that case, I'd assume it must be a general problem with sizing when using HiDPI displays. In that case, support for HiDPI is going to have to be implemented in some form eventually...

CodyCam is using the layout API, but it is using it incorrectly; the BBox comes with its own layout that makes sure the label is taken into account. However, the code sets a new layout on the BBox, causing the issue -- it uses a hard coded top offset that hides this bug in the 'normal' font size case.

comment:8 by pulkomandy, 6 years ago

And the fix, if anyone wants to tackle it, is to add an extra BView as the BBox only children, add the grid layout to that, and add the children there.

Does hrev50853 also fix Video source view alignment?

comment:11 by humdinger, 6 years ago

Not sure what exactly you mean. The top box that's supposed to show the video source is centered horizontally in the window. It keeps centered when resizing the window.

comment:12 by diver, 6 years ago

Shouldn't it spread horizontally across the window or its geometry supposed to be like that?

comment:13 by humdinger, 6 years ago

I guess we'll only know if we get support for a real video source... if it can stretch, we can re-enable vertical resizing and scale the video box. Until then it's fixed size and aspect.

comment:14 by pulkomandy, 6 years ago

The video view should rescale when it manages to find a video source. You need one of the working "sonix" webcams, or I can send you a patched UVC driver, which somewhat works (shows only a black area for me, but at least it detects the webcam) for testing.

Sure PulkoMandy, I can give it a try. Maybe upload it somewhere.

Hi, I would like to work on this issue, I'm new to Haiku so i might need some guidance.
