Use a CStr instead of str, to avoid an extra CString allocation. The underlying operating system API for
this expects a zero terminated C String.
Fixes#1943
* Add `RequestedSize` and `RequestedPosition` enum to enable asking for
logical or physical size/position.
* Rename `Window::size()` to `Window::physical_size()`
* Make `Window::set_size(...)` take an `Into<RequestedSize>`
* Rename `Window::position()` to `Window::physical_position()`
* Make `Window::set_position(...)` take an `Into<RequestedPosition>`
* Change `WindowAdapter` and related classes to be able to handle
requests being made in the either physical or logical units.
Implement this for C++, Rust and node.
The old workaround doesn't work anymore (commit
575665994a removed the
redraw_all_windows() but that was correct as well). Instead we take an
approach that is hopefully more idiomatic to winit:
The winit documention suggests two methods: For continuously repainting
windows, we can just draw in MainEventsCleared. Otherwise call
request_redraw() and wait for Event::RedrawRequested(id).
In practice sometimes a call to request_redraw() from within the input
event processing results right away in a Event::RedrawRequested
(observed on Windows). Sometimes a request_redraw() results in waking up
with NewEvents() but no Event::RedrawRequested, and then in the next
iteration a new request_redraw() is included (observed on Windows).
We will continue to issue request_redraw() but for any windows that
haven't received Event::RedrawRequested() we will just draw. This still
allows the windowing system to compress / combine paint events.
If during draw() request_redraw() is called, we assume that the
application wants to redraw ASAP and we fall back to Poll. This was
previously the workaround in corelib that's now only in the winit code.
Fixes#1574
- We must first set change the constraints before changing the size
otherwise the new size might not be in the old constraint and the
change might not take effect.
- We must update the WindowItem's size even if the size of the window
doesn't change. This happens when a component is set on a window that
that doesn't change it size (eg, preview) but for which we need to
set the geometry on the window
The test backend can no longer support this.
Because Tests might be called from different thread and the backend with
an event loop can only be set on one thread. So the test backend can't
implement new_event_loop_proxy()
Previously: Window is an Rc<WindowInner>, which has an Rc<dyn
PLatformWindow> - and weak references the other way around.
Now: Rc<dyn PlatformWindow> is the root of window ownership. The impl
PlatformWindow has a slint::api::Window, which just holds a WindowInner.
This change is incomplete on a few levels, mainly that neither of the
code generators nor the interpreter is ported.
This field duplicates the winit window's inner size. It is set on a
WindowEvent::Resized(), after which
`winit:🪟:Window::inner_size()` returns the same value.
