Not requesting desktop content when connected to monitor

[Bill Filler]

The ua string is supposed to change based on screensize and other hueristics, but this is not happening. Getting mobile ua string always, even when connected to monitor via slimport

using this build:
(r112) ubuntu-device-flash touch --channel=ubuntu-touch/rc-proposed/ubuntu-pd

Not seeing any messages in the browser log when I plug/unplug the monitor

Qt not being told the screen changed. Qtubuntu work

Isn't this the same as https://bugs.launchpad.net/bugs/1504084 ?
I see that it was fixed already but I assume it hasn't landed yet on vivid channels since the package mentioned was for Xenial.

[Olivier Tilloy (osomon)]

No, it’s a slightly different issue: bug #1504084 was an issue in the browser app, this bug is in qtubuntu.

[Gerry Boland (gerboland)]

I've attached the QtUbuntu branch which
1. correctly updates applications of the screen their window is on, so the Screen information is correct
2. has getters and notifiers for these properties: scale & form factor

This branch relies on a QtMir branch to function correctly. All in progress

[Olivier Tilloy (osomon)]

Any update on this?

[Gerry Boland (gerboland)]

Yep, as of now, you can fetch the shell mode by using the QPlatformNativeInterface::windowProperty api to fetch a "formFactor" property which will return an enum (look in mir for the enum interpretation) indicating what mode the shell is in. Connect to windowPropertyChanged for signal on change.

This is an intermediary means of accessing this info, and it is clunky. The UITK needs to grow a proper API for this. Lemme know if you need a hand.

[Olivier Tilloy (osomon)]

@Gerry: I’m aware of that new API to get the "formFactor" value, but I was referring to the original issue of the window’s screen property not being updated, see the first comment (the browser relies on the size of the current screen to decide whether to advertise a desktop or a mobile UA string). Is that fixed?
