When the TextInput item is read-only, it should not report availability
or any other status to the input method via the window adapter.
This also fixes the order of events when clicking on a TextInput: We
would send the ime position update request before enabling the ime,
because we set the focus _after_ setting the cursor pos.
Fixes#2812
Add WindowEvent::ScaleFactorChanged and made set_scale_factor on
WindowInner private.
This achieves what #2486 tried to do, but using the clean platform
window event interface.
Make text_input_byte_offset_for_position and text_input_cursor_rect_for_byte_offset
low-level in the API, where the implementation becomes easier. Two
helper functions in TextInput in turn collect the necessary parameters
and thus also reduce the amount of duplicated code.
This also decouples the renderer further from the window.
Replace register_root_component in the WindowAdapterSealed altogether with
a default font size getter on the renderer.
This is overall simpler and allows removing the doc-hidden getter in the software renderer.
* 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.
and use Rc<dyn PlatformWindow> instead. The alias has to stay with the ffi
functions though and the item vtable definitions,
because we don't have an Rc<> template in C++.
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.
For hide() we don't really need Rc<Self>, and for show() we had Rc<Self> because
for example for winit we need a Weak<Self> for the thread-local mapping of
window id to window.
However that can be encapsulated in the PlatformWindow impl using Rc::new_cyclic,
there's no need to expose this in the trait.
Move the self_weak of WindowInner into the impl of PlatformWindow. Most implementations already have it anyway.
While right now the method returns a `WindowRc`, at the end of the series
it should return a `&Window`.
From that `&Window` we can get to `&WindowInner` and all receivers there
are `&self`.
Every backend will do something different with the string that needs to go into the clipboard.
Qt will convert it to a QString, copypasta to a String, in theory it could be written
directly to a socket.
Given that we don't know what the perfect representation on the backend side is, passing
a string slice avoids any immediate conversions.
