Make the panel class provide a cancellable that will be cancelled when the panel
is destroyed. Panel implementations can use this and not have to mangage the
cancellable themselves. Consolidate cases where panels had multiple cancellables
that were all being used for this behaviour.
Some devices have panels with a native resolution in portrait mode. In
these cases the monitor will likely be used in landscape mode.
Accept the modes as if they are landscape rather than portrait. A
further improvement would be to restrict the orientation setting.
Fixes#639
This may happen under some conditions. Possibly due to a race condition
(i.e. we did not receive any configuration from mutter yet) or also if
we are not running on GNOME.
Add guards for NULL configuration. This configuration is never
applicable and mostly clears the UI.
Fixes: #604
This introduces a GtkStack to handle the pages; move the
current panel to be the "displays" page; and adds the
Night Light page as "night-light".
A stack switcher was added, as a header widget, to control
the stack.

In almost all cases, the configuration will be "valid" in the sense that
g-c-c can represent it in the UI. However, there are cases like
mirroring setups with three monitors that we do not allow.
In case that the user has such a configuration, ensure that the
configuration we represent is actually valid according to our
expectations. This should not affect normal use cases, but allows users
to recover again if the configuration is broken for some reason.
Fixes#383
When the user has more than two monitors, then they can disable each
monitor separately. If the user creates an invalid configuration because
they disabled the last monitor, then enable a different one immediately.
The new logic selects a single configuration type rather than detecting
which types can be considered valid. This simplifies the UI rebuilding
somewhat, but also changes some internal behaviour. We will now always
be in the correct mode internally, even if the UI may not represent this
change (i.e. with more than two monitors it always looks the same).
We should show unusable monitors in the monitor selection drop-down
list. So always add them to the combobox and add the code to make the
switch to enable them insensitive.
We should only enforce single mode, when we have exactly two monitors
and the two button UI is used to switch between them in single mode.
Move the code to ensure the single configuration into the relevant
callback handler, rather than trying to solve this globally.
We need to also set rebuilding while updating some other UI elements.
Make it into a counter to allow for recursive setting.
Note that additional checks for rebuilding will be added in later
commits.
It generally makes more sense to reset the resolution of a monitor after
we switch configuration types. The main case where this is relevant is
switching from a mirror configuration (CLONE) to either join or single.
In this case, higher resolutions for monitors may become available.
Note that this might be annoying to some users, because there may be
monitors reporting a lower "preferred" resolution than the highest
supported resolution. There is little we can do though, as always
selecting the highest resolution doesn't seem like a much better
approach.
The new code had a bug in that it only ever enabled the first monitor
rather than all usable ones. Fix this by removing the erroronuous break.
Also clarify the comment a bit that the current solution is not really
ideal as it may result in invalid configurations (i.e. we enable more
outputs than are possible with the number of available CRTCs).
Fixes#418
As per the binding that we have between the list store and the combo-box, when
the first element is added to the list-store, the combo box set this value as
the selected-index, and this leads to a call to cc_display_monitor_set_primary
which set the first-listed monitor as primary and unset the real primary monitor.
To avoid this, just ignore the binding when rebuilding the UI, since in this
phase control-center should just reflect the actual state without changing
anything.
Fixes https://gitlab.gnome.org/GNOME/gnome-control-center/issues/419
In the case where the user plugged/unplugged a screen, we could run into
the case where we would first enable and then disable the same output.
This could potentially result in an invalid configuration.
Prevent this by not disabling the output if no switch happened.
The dialog tried to retain the current configuration mode. However,
doing so means that we end up in the wrong mode in some situation (e.g.
opening the dialog with two displays but only one enabled).
Fix this by always selecting a configuration mode. This potentially
switches the user from "join" to "single" if only one monitor is left.
However, the user has no way to do this manually, so no unexpected UI
change will happen.
We were converting the floating point numbers to integers using a cast,
which causes them to be always rounded down. The result is that a
monitor may be too small by a pixel, creating broken configurations.
Also fix the same issue when calculating whether a scale should be
supported.
See https://gitlab.gnome.org/GNOME/mutter/issues/412
Anything that affects the size of the screen (or its existance) may
result in invalid configurations. Do a small effort in trying to fix
this by calling into the snapping algorithm for the modified monitor.
Addresses issue #247 to a large extend.
Previously, low resolutions were hidden from the control center
because when such display modes are activated, GNOME is unusable;
many important UI elements do not fit on the screen at all.
https://bugzilla.gnome.org/show_bug.cgi?id=626822
This was removed in c0f686bb0f
without explanation; reinstate it here.
Also prevent the scaling from being selected or activated if the
effective scaled resolution would result in an equivalently low
resolution being used.
We need to re-sync the scale button scale when updating the state
dynamically. Otherwise changing the resolution will always show a scale
of 100% (first item) rather than the actual active one.
The visibility is explicitly controlled in the functions that create the
rows in question. This regression was introduced in commit 3d177b67
(display: Don't use gtk_widget_show_all).
As the main headerbar used by the shell is split, the title is not
propagated to the window. However, the "apply" header bar is not split
and the title is propagated to the toplevel GtkWindow.
Fix this issue by resetting the window title again.

This commit improves the Night Light code in various
ways:
* Turn it into a template class, subclass of GtkDialog,
and adapts all the code to reflect that.
* Update the code style in various places, to make it
more conformant with the documented code style.
* Reorganize the code a bit, moving functions around,
to make it more conformant with the documented order.
This adds the following API:
* cc_display_config_get_ui_sorted_monitors
Returns the monitors in UI order
* cc_display_config_count_useful_monitors
Counts the useful monitors (active and usable)
* cc_display_monitor_is_useful
Checks if a monitor is active and usable
* cc_display_monitor_is_useable
Check if a monitor is marked as useable
* cc_display_monitor_set_usable
Used to mark builtin monitors as unusable if the lid is closed
* cc_display_monitor_get_ui_*
Get the UI number and strings for display

Remove the code that has become unused with the new arrangement widget.
There are more possible cleanups as there is some code duplication
between cc-display-panel.c and cc-display-arrangment.c at this point.
https://bugzilla.gnome.org/show_bug.cgi?id=786971
This commits adds a new arrangement widget, refactoring the existing
code and addressing a number of issues:
* Forced snapping made laying out more than 2 monitors hard
* Random gaps would be shown between monitors
* The scaling was fixed and usually tiny

When the user creates temporary invalid configurations the dialog used
to hide the apply button as if no change had been done so far. Change
this to show the normal "Apply"/"Cancel" titlebar but make the "Apply"
button insensitive and modify the title to indicate the error.
Unfortunately we don't currently get the reason in a way that we could
translate it. Ideally we would special case common error scenarios and
present the user with a better explanation or even correct the mistake.
See https://bugzilla.gnome.org/show_bug.cgi?id=790891 for the related
mutter bug.

The GVariant constructed here would be useless otherwise, since there are
no outputs to show the labels for. Besides, calling g_variant_builder_close
in this scenario would hit an assertion and the program would crash.

When switching between screen mirroring and joining displays the
configuration needs to be reset. Otherwise the monitor scaling will
not be set back to the current scaling again.
Split out the code to reset the current configuration and call that when
the mode is switched to ensure the changes are minimal.
