Detailed Description

This class watches for output ordering changes from the relevant backend.

Definition at line 27 of file outputorderwatcher.h.

Constructor & Destructor Documentation

◆ OutputOrderWatcher()

OutputOrderWatcher::OutputOrderWatcher ( QObject * parent)
protected

Definition at line 70 of file outputorderwatcher.cpp.

Member Function Documentation

◆ instance()

OutputOrderWatcher * OutputOrderWatcher::instance ( QObject * parent)
static

Create the correct OutputOrderWatcher.

Definition at line 86 of file outputorderwatcher.cpp.

◆ outputOrder()

QStringList OutputOrderWatcher::outputOrder ( ) const

Returns the list of outputs in order.

At the time of change signalling all Screens are guaranteed to exist in QGuiApplication.

After screen removal this can temporarily contain dead entries.

Definition at line 129 of file outputorderwatcher.cpp.

◆ refresh()

void OutputOrderWatcher::refresh ( )
virtual

For X11 we know libkscreen takes a server grab whilst changing properties. This means we know at the time of any runtime screen addition and removal the priorities will be up-to-date when we poll them.

For dynamic ordering changes without screen changes we will get the change property multiple times. A timer is used to batch them.

A caveat on X11 is the initial startup where plasmashell may query screen information before kscreen has set properties. This should resolve itself as a dynamic re-ordering when kscreen does start.

For wayland we know kwin sends the priority order whenever screen changes are made. As creating screens requires an extra async call to kwin (to bind to the output) we always get the new priority ordering before and screen additions. We should always have correct values on startup.

Definition at line 100 of file outputorderwatcher.cpp.

◆ useFallback()

void OutputOrderWatcher::useFallback ( bool fallback)
protected

Backend failed, use QScreen based implementaion.

Definition at line 77 of file outputorderwatcher.cpp.
