When invalidating the frame we need to properly flag that so that
we trigger rendering the frame, even if "all" was flagged as being
invalidated. Otherwise it will only get rendered if anything else
happens to trigger it (such as focus change).
Fixes#3427
Do not fill the backing store mismatch area with the solid window
color if the window is transparent. This caused some minor flicker
when such a window is e.g. snapped to the left/right or maximized.
When a resize_aspect_ratio is specified, and window will only be resized
to a multiple of that ratio. When resize_aspect_ratio is set, windows
cannot be tiled.
We need to clip painting to the actual size to prevent corrupting
the area outside of the applet as the backing store is not
guaranteed to be perfectly in sync.
Fixes#3107
If a modal window is being minimized, it may not have its own
taskbar rectangle. In that case, try finding a parent in the
modal window stack that does have one, and use that for the
animation.
Rather than blitting and rendering each window every time, only
render what actually changed. And while doing so, only render
the portions that are visible on the screen. This avoids flickering
because flipping framebuffers isn't always perfectly in sync with
the code, so it's possible that the flip happens slightly delayed
and we can briefly see the next iteration having partially completed.
Also, avoid touching the mouse cursor unless it is in an area that
needs updating. This reduces flickering unless it is over an area
that is updated often. And because we no longer render the entire
screen, we'll save the contents below the cursor so that we can
hide it before touching that area.
Fixes#2981
This finally makes tooltips on menu applets the same as everywhere else!
Here's what went wrong:
WindowManager::process_mouse_event() receives a Window*&, determines the
hovered window and sets it accordingly. However there's a branch that
tests for menubar_rect().contains(event.position()) and returns early -
which resulted in hovered_window never being set to any MenuApplet
window, even hovered ones.
The hovered_window result is being used in WindowManager::event() and
passed to WindowManager::set_hovered_window(), which is responsible for
creating WindowLeft and WindowEntered events when the hovered window
changes, as a result of the mentioned chain of events this also never
happens for MenuApplet windows.
The WindowLeft event would the cause Window::handle_left_event() in
LibGUI to be called, which unsets the window's hovered widget, which
is necessary for the widget to receive a subsequent Enter event -
again, all of this never happened.
Now it's working as expected though, so we can start using tooltips on
menu applets :^)
In the case of an ongoing window drag/move/resize action
WindowManager::process_mouse_event() would return early, even before
delivering mouse events to windows with global cursor tracking enabled.
They would only continue to receive new mouse events once those actions
were completed.
Fixes#3116.
When maximizing a window that is blocked by a modal window, only
maximize the top window in the stack. However, if the stack is
minimized, restore all of them in addition.
Fixes#3074
This patch introduces the ClassicWindowTheme, which is our default
theme implemented as a Gfx::WindowTheme subclass.
In this initial cut, we move normal window frame painting and title
bar metrics helpers out of WindowServer and into LibGfx.
This will eventually allow us much greater flexibility with theming
windows, and also makes it easier to build applications that want to
render a window with a specific style for some reason. :^)
When clicking on a window's frame that is blocked by a modal
window, we want to bring the entire window stack to the front
regardless of where the user clicked in the frame (not just the
icon).
Change #2811 made window title stripes and window title shadow themable,
but it used the same stripe and shadow color for all window modes.
This is fine for the new 'basalt' theme which uses the same color
in all four window modes, but it changed the default theme so that
background windows had brown stripes and a brown shadow.
Instead, make the title stripe and title shadow themable per window mode,
and change the default theme to restore the colors it had before
change #2811: The title stripe color is the same as Border1 for all
window modes, and the title shadow is the same as the title stripe
darkened by 0.6.
This prevents windows from being opened directly on top of eachother,
and provides default behavior for when window position is not specified.
The new behavior is as follows:
- Windows that have been created without a set position are assigned one
by WindowServer.
- The assigned position is either offset from the last window that is
still in an assigned position, or a default position if no such window
is available.
Custom buttons can now be set using TitleButtonIcons under the
Paths group in themes. WindowFrame recognizes window-close.png,
window-minimize.png, window-maximize.png and window-restore.png
filenames.
If we add "(Not responding)" to the title of an unresponsive window,
the title rect needs to be wider or we'll have text-on-stripes.
Thanks to @SharpOB for reporting this bug!
The theming system can now control title bar height, title button
size, title stripe color and the title text shadow color.
The implemented theme metrics system could be later extended to LibGUI
to allow themes to change widget padding, border width, etc.
When walking the modal window stack upwards, we need to check if
the top modal window is still a descendant of the window that
the parent is blocked by. Fixes not all windows being brought to
the front when trying to active a parent in the middle of the
modal window stack.
* The parent information is necessary by the Taskbar to be able to
determine a modal window's parent
* Minimize and maximize modal window stacks together
This fixes a few problems with modal windows:
* If any child window, or any child window further down the
tree is considered modal, then all windows in that chain
are modal.
* When trying to activate a window blocked by a modal child
bring the entire stack of modal windows to the front and
activate the modal window.
* A window is modal if it has a parent and it's flagged as
modal, regardless of whether the ClientConnection has
created modal windows.
This technically supports diverging modal window trees as well,
where two modal windows share the same parent, allowing both to
be activated (including for input) but not the parent. And it
should also support modal window stacks of arbitrary depth.
This solves a problem where windows don't receive a WindowInputLeft
event when popup menus are opened. This prevented ComboBox being
closed when right clicking the application on the task bar.
Accessory windows are windows that, when activated, will activate
their parent and bring all other accessory windows of that parent
to the front of the window stack. Accessory windows can only be
active input windows. The accessory window's parent is always the
active window regardless of whether it is also the active input
window.
In order to route input correctly, input is now sent to the active
input window, which can be any accessory window or their parent,
or any regular window.
This allows marking a MenuItem as a default action, e.g. in a
context menu for an action that reflects what e.g. a double click
would perform.
Also enhance the window menu to mark the close action as the
default, and when double clicked perform that action.
