Some Windows apps cause user32 to flush the window surface much faster than the
display refresh rate. The Mac driver only marks its window as needing to be
redrawn and lets Cocoa decide how often to actually redraw. Unfortunately,
Cocoa redraws each time through the run loop and, since the Mac driver uses a
run loop source to convey messages from background threads to the main thread,
it redraws after every batch of messages.
On some versions of OS X, this excessive drawing provokes synchronization with
the window server's buffer swaps, preventing the main thread from being
responsive. Even when that doesn't happen, it's wasteful.
So, we set our windows' autodisplay property to false so that Cocoa never
displays windows itself. Then, we arrange to call -displayIfNeeded once per
display refresh cycle using a CVDisplayLink. We maintain one CVDisplayLink per
display (on demand), move windows among them as the windows change screens,
start them when they acquire their first window, and stop them when they have
none left.

Some apps create a zero-sized window as their "main" window and then create
all of the other top-level windows as owned windows with that main window as
the owner. The user interacts with these owned windows. When the user
attempts to minimize one of these owned windows, the app instead minimizes the
zero-sized owner window. When an owner window is minimized, all of its owned
windows are hidden.
The Mac driver faithfully carries out these window operations. The only
visible windows are hidden and the zero-sized window is minimized. This
results in an invisible animation of the window down to a slot in the Dock -
a slot which appears mostly empty. The invisible window thumbnail is badged
with the app icon, but it still looks strange.
On Windows, the Alt-Tab switcher uses the image of the owned window to
represent the zero-sized owner.
This commit attempts to do something similar. It takes over drawing of the
Dock icon for minimized, zero-sized window. It grabs a snapshot of one of the
owned windows and draws the app badge onto it. Since the owned windows are
hidden before the zero-sized owner is minimized and we can't take snapshots of
hidden windows, we use heuristics to guess when it may be useful to grab the
snapshot. If the user minimizes an owned window from the Cocoa side, we grab
that window's snapshot. If an owned window is being hidden and no snapshot has
been taken recently, we grab its snapshot on the theory that this may be the
beginning of hiding all of the owned windows before minimizing the owner.
Unfortunately, this doesn't address the invisible animations when minimizing
and unminimizing the zero-sized owner window.

When the display mode changes such that the screen height changes, we'd like
our windows to keep their position relative to the top-left of the primary
screen. That's how WinAPI's coordinate system works and we want the WinAPI
position of the window to not change just because the display mode changed.
Unfortunately that's not achievable in Cocoa. Cocoa keeps the window
stationary relative to the screen it's on, not necessarily the primary screen,
and it's sometimes relative to the bottom-left and sometimes the top-left of
that screen.
So, what we do instead is queue an event to get the back end to reassert the
WinAPI position of the window. This is queued before Cocoa can adjust the
Cocoa position of the window which would queue a WINDOW_FRAME_CHANGED to the
back end and mess up the WinAPI position. The back end's reassertion of the
WinAPI position won't be processed by the Cocoa thread until after Cocoa has
adjusted the position and will thus override it. It will also discard any
wrong WINDOW_FRAME_CHANGED that may have been queued.

The default behavior is that GL surfaces are on top of all non-GL content in
the window. This maximizes the performance for the common case of games, but
clipping by parents, siblings, and child windows isn't respected.
Setting OpenGLSurfaceMode to "behind" pushes the GL surface to be behind the
Mac window. The window has transparent holes punched through it so that the GL
surface shows through. USER32 and the wineserver take care of making sure the
holes are only where the GL windows would be unclipped and unoccluded. Because
the OS X window server has to composite the GL surface with the window, this
limits the framerate.
Since the Mac driver has no server-side rendering path, GDI rendering to a
window which has a GL surface doesn't work. As a partial workaround, mostly
for cases where a GL surface is created but never used, setting
OpenGLSurfaceMode to "transparent" allows the GDI rendering to show through the
transparent parts of the GL surface. The GDI rendering is drawn to the
top-level window's surface as normal. (The behavior of user32 to exclude the
portion covered by a GL window from GDI rendering is disabled.) The GL surface
is in front of the window but potentially wholly or partially transparent. It
is composited with the window behind it.
The GL surface is initially cleared to be completely transparent. So, if
no GL rendering is done, the window will appear as though the GL surface didn't
exist.
OS X doesn't have the same concept of maximized windows as Windows does.
There's no mode that prevents a normally-movable window from being moved. If
a window is "zoomed", it mostly fills the screen but the user can still move
or resize it, at which point it ceases to be in the zoomed state. So, users
are confused and frustrated when they can't move a window that's maximized.
To get similar behavior while still respecting Win32 semantics, we detect when
the user tries to move a maximized window. When they start, a request is
submitted to the app to restore the window. Unless and until the window is
restored, we don't actually allow the window to move.
The user expects to move the window from its current (maximized) position. It
should not jump to its normal position upon being restored. So, we set the
window's normal position to its current position before restoring it.

There's no mode that prevents a normally-resizable window from being resized.
If a window is "zoomed", it mostly fills the screen but the user can still
move or resize it, at which point it ceases to be in the zoomed state. So,
users are confused and frustrated when they can't resize a window that's
maximized.
To get similar behavior while still respecting Win32 semantics, we now let the
user try to resize maximized windows. (The resize cursors are shown at the
edges of the window frame.) When they start, a request is submitted to the app
to restore the window. Unless and until the window is restored, we don't
actually allow the window to change its size.

It should not jump to its normal position upon being restored. So, we set the
window's normal position to its current position before restoring it.
OS X doesn't really have the concept of windows being maximized; that is, being
in a mode where they can't be moved or resized. As a consequence, it doesn't
have a button in the window title bar to restore a maximized window to normal.
So, when a Wine window is maximized, the Mac driver hijacks the green zoom
button to act as a restore button. (When a window is zoomed, the green button
"unzooms" back to its last user size and position, so it's analogous.)
However, with OS X 10.10 (Yosemite), the green button prefers to act as a
toggle for the Cocoa full-screen mode rather than zooming and unzooming. This
made it difficult for users to restore a maximized window. They would have to
Option-click the green button, double-click the title bar, or choose Zoom
from the Window menu, none of which is obvious.
The fix is to disable Cocoa full-screen mode for maximized windows. Then, the
green button reverts to unzoom and restoring the window.
Status items are the things on the right end of the Mac menu bar, like the
clock and volume widget. It turns out that they are displayed at a higher
window level than everything else in the menu bar. For the case where the
displays are not captured for a full-screen window, the window ends up at the
same window level as the status items, and they would sometimes end up on top.
They would draw over the full-screen window and could be clicked.
On high-resolution Retina displays, the OS X window backing store has twice the
pixels as Wine's window backing store. So, our images get scaled up. Core
Graphics had been interpolating/smoothing the image, which resulted in
fuzziness. This tells it not to do that.
I had assumed this wouldn't be necessary since we pass FALSE for the
shouldInterpolate parameter of CGImageCreate() when we create the images.
Apparently, that's not sufficient.
On Yosemite, in full-screen mode, Cocoa adds child windows of its own to our
windows. These windows are, of course, not instances of WineWindow. So, when
we call WineWindow-specific methods on them, it throws exceptions.
On Yosemite, double-clicking a window's title bar zooms it. (This is to
compensate for the fact that the zoom button has been replaced by a full-screen
button.) Sometimes, double-clicking in the content area would count as double-
clicking in the title bar.
This is controlled, in part, by the -mouseDownCanMoveWindow method of the view
that was hit in the window. The default implementation of that returns YES
for non-opaque views, as the views are in the Mac driver. Overriding it to
return NO prevents the problem.
NSBezierPath doesn't override the -isEqual: method to actually compare paths,
so it just falls back to object identity which, in our case, makes paths seem
like they're never equal.
Also, memcmp()-ing the rectangle array is almost certainly faster than any
general test for equality between two paths.
This avoids flickering and tearing on some versions of OS X during frequent
redrawing in a shaped window, such as when scrolling a document in Word 2007.
Since we aren't guaranteed that the window surface has updated bits for us to
draw, we mark the whole content view as needing redisplay and draw the window's
shape in the background color on the first -drawRect: after the shape change.
Many games clip the cursor to the client area of the window. However, on OS X,
the resizing controls extend into that client area. So, it's possible that
while playing, the user might unintentionally click in the resizing area and
drag, resizing the window.
Among other things, this fixes Syberia 2. That game shows, hides, and then
shows its window. Hiding it caused a WINDOW_LOST_FOCUS event to be queued.
By the time it was processed, the window was the foreground window again.
In response to being told it had lost focus, the game minimized its window.
Hiding the window should have prevented or discarded the WINDOW_LOST_FOCUS
event since the change was driven from Wine and the Win32 foreground/active
window state would already be correct. In addition, when the program
re-showed its window and made it foreground, that should have discarded the
event as being out of date. Now they do.
Cocoa would implictly unhide it when we order a window, anyway. Doing it
early avoids problems from querying -[NSWindow isVisible] while the app is
hidden. That method returns FALSE even for windows which would be visible
if the app weren't hidden.
The -[NSWindow isVisible] method returns FALSE when the process is hidden,
but that's not what we need to know in some cases.
This fixes full-screen games which minimize their window when they lose
focus. Command-Tabbing away hides the process. Because the window was not
visible, the code didn't actually minimize it. When switching back to the
process, no event was sent to the Wine back-end telling it the window had
been restored, so it never resumed drawing to it.
The user is prevented from moving or resizing a maximized window. The zoom
button is still present and enabled for a maximized window but requests that
it be restored rather than simply resizing it, which is what it does for
normal windows.
If a window is not resizable (lacks WS_THICKFRAME) but has a maximize box
(WS_MAXIMIZEBOX), then the zoom button requests that it be maximized rather
than resizing it.
This fixes a problem where some apps move their window to the front after
the user switches away to another app. OS X prevents the background app
from actually coming in front of the active app's front window, but the
window gets ordered in second place, possibly obscuring other windows of the
active app.
It has a non-object pointer from the caller, so it can't allow the caller
to continue until it's finished with it. Also, it discards events from the
event queue and we don't want the caller to process them first.
Fixes brokenness introduced by 784a9139.
Some programs minimize windows which are outside of the desktop. The Mac
driver had been leaving such windows ordered out, which prevented them from
minimizing and appearing on the Dock. That, in turn, made it difficult for
the user to restore them.
Queries can be run out of order because the main thread is waiting on the
response. The main thread didn't really need a response from QUERY_RESIZE_END.
It was only a query for symmetry with QUERY_RESIZE_START.
The Mac driver was already sending these events when the user resizes the
window by dragging its corner/edges, but there are other occasions when the
window frame changes. For example, when the user zooms the window.
This fixes a problem where windows could spontaneously re-minimize after
being unminimized. Cocoa would see the window unminimize. It would queue
a WINDOW_DID_UNMINIMIZE event. While that event was pending, Wine might do
something which caused set_cocoa_window_properties() to be called and tell
Cocoa to conform itself to the current Win32 state. The current Win32 state
still had the window minimized, so Cocoa would re-minimize the window. It
would even discard the WINDOW_DID_UNMINIMIZE event.
Cocoa won't order a minimized window out of the screen list using -orderOut:.
This leaves a window that should be hidden still visible in the Dock, where
it can be unminimized.
That event can confuse things if the program switches focus from A to B and
then back to A and then processes events. It will get an event saying that
A lost focus in Cocoa, check that A does indeed have current focus in Wine,
and so switch focus away from it (to the desktop window). (It then gets an
event that B lost focus, but that does nothing at that point.)
The Cocoa parent-child relationship has undesirable side effects and bugs. In
the general case, it's the only way to maintain the z-order of owned windows
relative to their owner. But when the owner is non-topmost and an owned
window is topmost, the Cocoa window level will enforce that and we don't
need it.
For keys pressed in combination with Command, -[NSApplication sendEvent:]
simply doesn't pass the key-up event through to the window. We have to
track which keys we've told Wine are pressed because Cocoa may consume
key-downs that trigger menus or system behaviors.
We generally prevent Cocoa from making our windows key (focused) so that
Wine can be in control. However, after unminimizing, Wine believes the
window is already focused but Cocoa doesn't, so key presses just cause beeps.
Added a registry setting to control the behavior: WindowsFloatWhenInactive
with possible values "none", "all, and "nonfullscreen" which is the default.
When we have windows on two different spaces and the user switches between them by
clicking our Dock icon, Cocoa inexplicably sends the switched-to window to the
back of the z-order. It's only -makeKeyAndOrderFront: that brings it forward
again, but our override broke that.
