This reverts commit 239520ae54.
The call to set_visible() is not redundant. Removing the call leads
to the "start" button in the taskbar not being painted as "pressed" even
when it is.
We've already returned early if the menu is open, so there's no need to
verify that it isn't present in the stack of open menus before pushing
it onto said stack.
WindowServer returns {} on non-existing screen index,
however shot program hangs instead of retriving an empty
ShareableBitmap. With this change, the function returns an empty
ShareableBitmap and shot exits gracefully.
This makes the cursor update properly if it was above the window
switcher while it was visible, and something underneath it wants to use
something other than the default arrow cursor.
...to reevaluate_hover_state_for_window(). This name is not super great
either, but at least it doesn't sound like the window is necessarily
currently being hovered.
In 2e6bb987a3 the "did_construct" API in
Core::Object was removed, since it had only one user. For a replacement,
the Window would manually call the frame's "frame_was_constructed"
method. However, WindowServer::Window has two constructors, and only one
of them called this method. This caused windows to spawn without
buttons and various other breakage that spawned from this.
Derivatives of Core::Object should be constructed through
ClassName::construct(), to avoid handling ref-counted objects with
refcount zero. Fixing the visibility means that misuses like this are
more difficult.
This commit is separate from the other Servives changes because it
required additional adaption of the code. Note that the old code did
precisely what these changes try to prevent: Create and handle a
ref-counted object with a refcount of zero.
Derivatives of Core::Object should be constructed through

There is also make_ref_counted(), which does not call did_construct(),
so the method was not guaranteed to be run. Since there is only a single
user, and `WindowServer::Window` is a final class anyway (so there is no
need to separate the constructor and post-constructor phases), let's get
rid of this concept.
(The following commits reduce the opportunities to call
make_ref_counted, but still.)
We create a base class called GenericFramebufferDevice, which defines
all the virtual functions that must be implemented by a
FramebufferDevice. Then, we make the VirtIO FramebufferDevice and other
FramebufferDevice implementations inherit from it.
The most important consequence of rearranging the classes is that we now
have one IOCTL method, so all drivers should be committed to not
override the IOCTL method or make their own IOCTLs of FramebufferDevice.
All graphical IOCTLs are known to all FramebufferDevices, and it's up to
the specific implementation whether to support them or discard them (so
we require extensive usage of KResult and KResultOr, together with
virtual characteristic functions).
As a result, the interface is much cleaner and understandable to read.
The Screen constructor already calls open_device(), so there's no need
to call it again right after creating a new Screen in apply_layout().
This makes the first screen compose happen ~50ms earlier on my machine.
This function only did one thing: call Screen::set_resolution().
We always call that function when opening the underlying device anyway,
so this was completely redundant.
This makes the first screen compose happen ~60ms earlier on my machine.
Add option to reverse primary and secondary buttons in Mouse Settings.
- WindowServer.ini: add default entry
- switch-mouse-buttons.png: new icon for settings entry
- Mouse.gml/MouseWidget.*: new settings dialog
- ClientConnection/WindowManager/Server: window message for settings
- EventLoop.cpp: swap buttons 1 and 2 if settings are on
If a mouse button was clicked, `EventLoop::drain_mouse()` would always
send the last MousePacket state to the screen input - even if that
state is equivalent to the last state sent as part of the button logic.
By remembering if the state was already sent, we prevent sending that
state a second time saving some resources in the process.
Currently, if there are not titlebar buttons, we fail to paint the title
because we treat the leftmost titlebar button as the empty rect. We will
now use the rightmost edge of the titlebar when there are no buttons.
This effectively makes us send a "mouse move" event to windows when they
become active, even if the mouse didn't actually move. By doing this, we
trigger hover/tooltip/etc logic immediately, instead of doing it on the
next 1px mouse movement.
It's a small detail but my goodness does it feel better this way. :^)
This fixes an issue for the magnifier that when the screen scaling is
increased to 2 the magnifier doesn't center around the cursor.
Since booting Serenity with multiple displays doesn't work at the moment
the rescaling is only added for the one display case.
This removes the awkward String::replace API which was the only String
API which mutated the String and replaces it with a new immutable
version that returns a new String with the replacements applied. This
also fixes a couple of UAFs that were caused by the use of this API.
As an optimization an equivalent StringView::replace API was also added
to remove an unnecessary String allocations in the format of:
`String { view }.replace(...);`
This allows any client to ask the WindowServer to give it the color
of the screen bitmap under the cursor.
There's currently no way to get the screen bitmap *without* the
cursor already drawn on it, so for now we just take a pixel
beside the actual cursor position to avoid just getting the cursors
color.
This feature was problematic for several reasons:
- Tracking *all* the user activity seems like a privacy nightmare.
- LibGUI actually only supports one globally tracking widget per window,
even if no window is necessary, or if multiple callbacks are desired.
- Widgets can easily get confused whether an event is actually directed
at it, or is actually just the result of global tracking.
The third item caused an issue where right-clicking CatDog opened two
context menus instead of one.
There are a few places in the system where this could be useful,
such as PixelPaint and the MandelBrot demo. It seems general enough
that it is probably useful to have it as a system-wide cursor rather
than loading it manually each time.
This can be used immediately in PixelPaint (separate commit), but
I am adding this as a system-wide cursor since it may also be useful
for other applications that want to use it.
Only one place used this argument and it was to hold on to a strong ref
for the object. Since we already do that now, there's no need to keep
this argument around since this can be easily captured.
This commit contains no changes.
Applets and windows would like to be able to know when the applet
area has been resized. For example, this happens asynchronously after
an applet has been resized, so we cannot then rely on the applet area
position synchronously after resizing. This adds a new message
applet_area_rect_changed and associated Event AppletAreaRectChange,
and the appropriate virtual functions.
Previously, when `screen_index` was not provided when calling
`ClientConnection::get_screen_bitmap`, the bitmap that was created
was always the size of the bounding rect of the screen. The actual
screen bitmap was being cropped, but the bitmap being returned was
of the original size with just black pixels everywhere else.
Now you can specify a CursorTheme key in /etc/WindowServer.ini. The
cursors are loaded from /res/cursor-themes/<name> directory. This
directory contains a Config.ini file with format similar to previous
Cursor section, except it uses relative paths.
This commit adds also Default theme, which uses cursors being
previously in /res/cursors.
The WidgetGallery is updated to match the new cursor path format.
