No need to have pointers to mutables when not needed.
This does not cover everything at all, and is limited to one file for
the moment.

The computed values are only used in one branch, so compute them there.
|
|
It's probably not necessary to perform the NULL check at all as the
only code paths that could make `list` NULL are already pretty
dramatically broken, but as we have a NULL check move everything
relevant inside it.

*Fix the window list menu replacing the panel context menu between the end of the window list and the next applet
|
|
This code got introduced with 3c21f66bf30810fcb25dfe8c3c0960df270dc416
trying to mimic `gdk_spawn_on_screen()`, but does not: what
`gdk_spawn_on_screen()` did (on X11) was to append the screen number to
the display, so that it worked on a multi-screen setup where the app is
not on the default X screen.
However, the code that got introduced just sets the display, which is
gonna be already there anyway (yet possibly loosing the default screen
in the process?), and AFAIK GDK dropped support for multi-screen setups
anyway (not to be confused with multi-monitor with e.g. Xinerama).
We should actually be better of without any of this, as it most likely
doesn't do what it is supposed to, nobody needs what it failed to do,
and it breaks XWayland on Wayland.
Fixes #1387.

`info` cannot be NULL, and if it was it'd already have crashed above.

This is not strictly needed as there's already an assertion (assuming
it's not compiled out), but returning a value help analyzers get this
right.
|
|
No need to get the default icon theme again anyway.

- Build the list in reverse order, then reverse the result. This is
useful because GS?List are list nodes, not containers of nodes, and
thus don't contain a pointer to the list's end, meaning to append one
has to walk the entire list to find the end each time. To avoid this
we use the common idiom of prepending to the list (which is cheap, as
it's adding a node before the given one), and then reversing the
resulting list to get back the original order.
- Avoid unnecessary memory copy by stealing the GStrv's members. We
get the array as a copy, so we can simply steal the members and free
the container array only, saving a copy for each member.

There is no need to return -1 or 1 specifically, anything on the right
side of 0 is OK, so simplify using the usual `a - b` implementation for
such sort functions.
Note that the type is OK here, as the `struct tm` are ints, the same as
the function's return value.

cppcheck tells us that we perform NULL checking inconsistently, and
reports a potential NULL dereference. Here however the string cannot
be NULL, so just drop the unnecessary check.

This is *not* an issue, as it's not really a bounds check but a mere
limit, and the array is NULL-terminated.
However, it looks odd and cppcheck (unsurprisingly) doesn't understand
the details well enough and reports this as a misordered bounds check.

*After replacing gtk_image_menu_item with mate_image_menu_item
*We must also replace GTK_TYPE_IMAGE_MENU_ITEM with MATE_TYPE_IMAGE_MENU_ITEM
*This fixes leftover GtkImageMenuItem deprecation warnings and restores missing Places and System icons in main menus

|
*For some reason "widget" is not being properly passed to this, so use NULL for the parent window
|
|
*This uses systemd to be able to shutdown when a display manager is running as root
*If no session or display manager is running as root, systemd used only to suspend or hibernate
*Suspend/hibernate require systemd at this point
*If suspend or hibernate not supported error dialog shown if those buttons clicked
*If "disable logout" lockdown option set, shut down button cannot be added same as in x11
*If shut down button added to panel and lockout later disabled, same non-responsive button as in x11
*Logind support would be welcome

*Compute the size of the monitor we are actually showing the popup on
*by getting the monitor it is shown on and running gdk_monitor_get_geometry()
*This returns application (scaled) pixels not device pixels

* There is only one screen in GTK 3.22 or later
* Finding the screen from that used by GtkPanelPlug is out of process only
* Any in-process applet calling mate_panel_applet_request_focus needs this to avoid a segfault
* One known user: dictionary applet
|
|
*Otherwise taskbuttons for programs using URLs or filenames in the window name can balloon across the whole taskbar
|
|
as necessary
*Empty space between buttons removed
*padding in buttons similar to x11
*Vertical panel: do not modify buttons, they just plain work!
*We have a working window list on vertical panels in wayland only
*Horizontal panels:
*expand buttons like in X11 until more expanded buttons won't fit
*When expanded buttons won't fit, resize buttons to fit tasklist
*When ellipsized text plus icon won't fit, remove the label
*When one more button with icon won't fit, remove the icon
*but bring back the (compressable) label as in x11.
*Prevents window list buttons disappearing when theme does not set a border
|
|
*Use automatic signal handling for changing icon size so this code doesn't get called when the applet is removed
