* Remove window subclassing
* Always call `DefWindowProcW` when we don't process a message
* Improve window initialization
Note that the error path in `init` is kind of cursed at the moment.
* Rename `ThreadMsgTargetCallbackData` to `ThreadMsgTargetData`
* Simplify window initialization
* Fix compilation on 32-bit targets
* Simplify the creation of the event target window
* Use `.clone()` rather than `Rc::clone()`
* Use concrete types for args to `SetWindowLongPtrW`
On 32-bit targets, `SetWindowLongPtrW` is an alias to `SetWindowLongW`,
which returns `LONG` (`i32`) rather than `LONG_PTR` (`isisze`).
* Minor comment adjustments
* Restore the ability to have fully transparent windows on Windows
Besides its original purpose, commit 6343059b "Fix Windows transparency
behavior to support fully-opaque regions (#1621)" also included some
changes considered cleanups, one of them was:
* Remove the `CreateRectRgn` call, since we want the entire window's region to
have blur behind it, and `DwnEnableBlurBehindWindow` does that by default.
But the original code actually disabled the blur effect for the whole
window by creating an empty region for it, because that allows for the
window to be truely fully transparent. With the blur effect in place,
the areas meant to be transparent either blur the things behind it
(until Windows 8) or are darkened (since Windows 8). This also means
that on Windows 8 and newer, the resulting colors are darker than
intended in translucent areas when the blur effect is enabled.
This restores the behaviour from winit <0.24 and fixes#1814.
Arguably, one might want to expose the ability to control the blur
region, but that is outside the scope of this commit.
* Remove useless WS_EX_LAYERED from transparent windows on Windows
`WS_EX_LAYERED` is not supposed to be used in combination with
`CS_OWNDC`. In winit, as it is currently used, `WS_EX_LAYERED` actually
has no effect at all. The only relevant call is to
`SetLayeredWindowAttributes`, which is required to make the window
visible at all with `WS_EX_LAYERED` set, but is called with full
opacity, i.e. there's no transparency involved at all.
The actual transparency is already achieved by using
`DwmEnableBlurBehindWindow`, so `WS_EX_LAYERED` and the call to
`SetLayeredWindowAttributes` can both be removed.
The issue was caused by calling SetCapture on a window which already
had the capture. The WM_CAPTURECHANGED handler assumed that it would
only run if the capture was lost, but that wasn't the case. This made
the handler to try to lock the window state mutex while it was already
locked.
The issue was introduced in #1797 (932cbe4).
This commit forwards "unknown" Wayland mouse buttons downstream via
'MouseButton::Other'. Possible values for those could be found in
<linux/input-event-codes.h>.
Also, since Wayland just forwards buttons from the kernel, which are
'u16', we must adjust 'MouseButton::Other' to take 'u16' instead of
'u8'.
This commit introduces a cross platform way to request a user attention
to the window via a 'request_user_attention' method on a Window struct.
This method is inspired by macOS's 'request_user_attention' method and
thus reuses its signature and semantics to some extent.
This patch removes an unneeded workaround for transparent windows on the
Windows platform. In addition, it simplifies a couple of related API calls:
* Remove the `CreateRectRgn` call, since we want the entire window's region to
have blur behind it, and `DwnEnableBlurBehindWindow` does that by default.
* Remove the `color_key` for `SetLayeredWindowAttributes`, since it's not used
(we're not passing `winuser::LWA_COLORKEY` to the flags).
This changes 'Fullscreen::Borderless' enum variant from
'Fullscreen::Borderless(MonitorHandle)' to
'Fullscreen::Borderless(Option<MonitorHandle>)'. Providing
'None' to it will result in picking the current monitor.
This commit is a follow up to a2db4c0a32
to make it clear which virtual key codes are located on numeric pad.
It also adds Asterisk and Plus virtual key codes.
Certain platforms like Wayland don't have a concept of
primary Monitor in particular. To indicate that
'primary_monitor' will return 'None' as well as in cases
where the primary monitor can't be detected.
Fixes#1683.
On certain platforms window couldn't be on any monitor
resulting in failures of 'current_monitor' function.
Such issue was happening on Wayland, since the window
isn't on any monitor, unless the user has drawn something into it.
Returning 'Option<MonitorHandle>' will give an ability to
handle such situations gracefully by properly indicating that
there's no current monitor.
Fixes#793.
On all platforms other than Linux/X11, the Subtract key was uniformly
used only for the Numpad. To make this cross-platform compatible, the
`-` key will now map to `Minus` on X11 instead of `Subtract`.
Since people have been confused about the difference between `Minus` and
`Subtract` in the past, the `Subtract` key has also been renamed to
`NumpadSubtract`. This is a breaking change that might be annoying to
downstream since there's no direct improvement, but it should help new
users in the future. Alternatively this could just be documented, rather
than explicitly mentioning the Numpad in the name.
This resolves various problems with the documentation about platform
support on the Window struct.
It also completely removes pointless runtime errors in favor of
consistent no-ops on all platforms that do not support a certain
features.
* On Windows, fix request_redraw() related panics
These panics were introduced by 6a330a2894
Fixes https://github.com/rust-windowing/winit/issues/1391
Fixes https://github.com/rust-windowing/winit/issues/1400
Fixes https://github.com/rust-windowing/winit/issues/1466
Probably fixes other related issues
See https://github.com/rust-windowing/winit/issues/1429
* On Windows, replace all calls to UpdateWindow by calls to InvalidateRgn
This avoids directly sending a WM_PAINT message,
which might cause buffering of RedrawRequested events.
We don't want to buffer RedrawRequested events because:
- we wan't to handle RedrawRequested during processing of WM_PAINT messages
- state transitionning is broken when handling buffered RedrawRequested events
Fixes https://github.com/rust-windowing/winit/issues/1469
* On Windows, panic if we are trying to buffer a RedrawRequested event
* On Windows, move modal loop jumpstart to set_modal_loop() method
This fixes a panic.
Note that the WM_PAINT event is now sent to the modal_redraw_method
which is more correct and avoids an unecessary redraw of the window.
Relates to but does does not fix https://github.com/rust-windowing/winit/issues/1484
* On Window, filter by paint messages when draining paint messages
This seems to prevent PeekMessage from dispatching unrelated sent messages
* Change recently added panic/assert calls with warn calls
This makes the code less panicky...
And actually, winit's Windoww callbacks should not panic
because the panic will unwind into Windows code.
It is currently undefined behavior to unwind from Rust code into foreign code.
See https://doc.rust-lang.org/std/panic/fn.catch_unwind.html
* add comments to clarify WM_PAINT handling in non modal loop
* made redraw_events_cleared more explicit and more comments
