Instead of just answering hit/no-hit when hit testing windows, we now
return a HitTestResult object which tells you which window was hit,
where it was hit, and whether you hit the frame or the content.
This feature had been there since early on and was not actually useful
for anything. I just added it because it was fun. In retrospect, it's
not a very good feature and I only ever activated it by accident.
This patch moves the window stack out of WindowManager and into its own
WindowStack class.
A WindowStack is an ordered list of windows with an optional highlight
window. The highlight window mechanism is used during Super+Tab window
switching to temporarily bring a window to the front.
This is mostly mechanical, just moving the code to its own class.
Use the configured desktop background color, if defined, otherwise
default to the current theme's background color. If a user chooses
a background color via "desktop settings", then this new color
will always be used.
Switching themes will delete the user-defined background color, so
the background color resets to the theme's defined color.
This patch adds a set_system_fonts() IPC API that takes the two main
font queries as parameters. We'll probably expand this with additional
queries when we figure out what they should be.
Note that changing the system fonts on a live system mostly takes
effect in newly launched programs. This is because GUI::Widget will
currently cache a pointer to the Gfx::FontDatabase::default_font()
when first constructed. This is something we'll have to fix somehow.
Also note that the settings are not yet persisted.
Problem:
- `static` variables consume memory and sometimes are less
optimizable.
- `static const` variables can be `constexpr`, usually.
- `static` function-local variables require an initialization check
every time the function is run.
Solution:
- If a global `static` variable is only used in a single function then
move it into the function and make it non-`static` and `constexpr`.
- Make all global `static` variables `constexpr` instead of `const`.
- Change function-local `static const[expr]` variables to be just
`constexpr`.
We were not substituting the window modified marker ("[*]") in the
title strings we were sending to WM clients. This caused the Taskbar
to show pre-substitution window titles for the Text Editor application.
This patch moves the window title resolution to Window::compute_title()
which is then used throughout.
Also update the window switcher for good measure. The window switcher
doesn't visualize this information at the moment, but we generally do
this when any window state changes.
When a new Window instance is added to the WindowManager, it does not
yet have an updated value for `m_frame->rect()` and we're not checking
if there is a new candidate for the hovered window, which we need to do
since the mouse cursor might hover above the newly opened window.
This fixes both issues: as soon as a Window frame's rect is changed,
ask the WindowManager to reevaluate its hovered window. This takes care
of newly opened windows _and_ windows that are programmatically changed
in size.
This works because when a Window becomes hovered, the WindowManager
sends out an enter event. This event in turn triggers the Window to
evaluate the cursor type under the mouse position and to update it when
necessary.
Fixes#4809.

This commit adds an event called WM_SuperKeyPressed which is sent to all
windows via WindowManagerServerConnection.
The event is fired from WindowManager when the super key is pressed,
which is the windows key on most keyboards :)
With this patch the window manager related functionality is split out
onto a new endpoint pair named WindowManagerServer/Client. This allows
window manager functionality to be potentially privilege separated in
the future. To this end, a new client named WMConnectionClient
is used to maintain a window manager connection. When a process
connects to the endpoint and greets the WindowServer as a window manager
(via Window::make_window_manager(int)), they're subscribed to the events
they requested via the WM event mask.
This patch also removes the hardcoding of the Taskbar WindowType to
receive WM events automatically. However, being a window manager still
requires having an active window, at the moment.
I hereby declare these to be full nouns that we don't split,
neither by space, nor by underscore:
- Breadcrumbbar
- Coolbar
- Menubar
- Progressbar
- Scrollbar
- Statusbar
- Taskbar
- Toolbar
This patch makes everything consistent by replacing every other variant
of these with the proper one. :^)
The desktop window is (and must be) considered resizable by
WindowServer, but none of the Super+<something> key actions should apply
to it (window minimizing/maximizing/tiling).
Fixes#5363.
This adds a double-click speed slider control to the Mouse Settings
panel, and value labels for both the movement speed and double-click
speed sliders.
To allow for updating and persisting the configured double-click
speed through the WindowServer, two IPC calls - `SetDoubleClickSpeed`
and `GetDoubleClickSpeed` - have been added.
WindowServer now collects applet windows into an "applet area" which is
really just a window that a WM (window management) client can position
via IPC.
This is rather hackish, and I think we should come up with a better
architecture eventually, but this brings back the missing applets since
the global menu where they used to live is gone.
This leaves menu applets running but invisible, and that's a regression
we need to take care of obviously. But not today, because it's getting
too late.
This patch begins the transition away from the global menu towards
per-window menus instead.
The global menu looks neat, but has always felt clunky, and there
are a number of usability problems with it, especially in programs
with multiple windows.
You can now call GUI::Window::set_menubar() to add a menubar to
your window. It will be specific to that one window only.
Because the z-order changes we not only need to recompute occlusions
but we also need to mark the screen area of the previous and new
highlighted window as dirty.
Fixes#5599
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
Also, only mark the menu bar item as opened if a menu was actually
opened through the menu bar.
These changes allow a menu to be used both in the menu bar as well
as a context menu.
Fixes#5469
