Under these windowing systems, we receive a QString text from Qt that
contains a terminal control character (like \u{3} for ctrl+c). We
decided to supply the character for the key (for example 'c' for Ctrl+C)
to the application, so activate the conversion from the key code when
control characters are present.
With winit, we receive first a key down input event with the virtual key
code (for example C for Ctrl+C), followed by a ReceivedCharacter event
with a terminal control character. We choose to ignore that and instead
take the previously received key code and try to use that instead.
Fixes#441
The RenderCache (slab and generation) is always in a refcell, so we can
just pass that through. This also eliminates the ItemGraphicsCache
wrapper in the GL backend.
This will allow more fine grained borrowing in the future.
There's only one place where we need this ourselves and that's also
easily done by hand. Otherwise the `as_bytes(_mut)()` accessor provides the
functionality along with `width()` and `height()`.
Other than that the API is mostly consuming, given that `sixtyfps::Image`
has no way of extracting the data again.
This adds an ImageBuffer and PixelBuffer type for SharedVector
backed images. The documentation explains how to use this
with low-level rendering functions and the popular image crate.
Fixes#387
If a Rectangle has a border-radius and clipping, we use an FBO to render
the children and then use femtovg's stencil clipping. If the Rectangle
has a zero width or height, we would end up trying to create a texture
with such dimensions, which produces run-time opengl errors.
We can detect this situation and avoid it early on. The same might happen for shadows.
Fixes#377
When the text selection end follows right after a grapheme that uses less
glyphs than characters, then there may not be a matching glyph with the byte
index, therefore we wouldn't set the selection_end_x and draw incorrectly.
Take the visual tail of the last glyph then.
Sixtyfps uses euclid already, so let's use euclid for float comparisons
as well.
I changed the code to decide whether a number is a positive integer to
make do without a comparison along the way.
That's all it is nowadays, it's a wrapper around Rc<Window>. It's not an
alias because we need to also "wrap" it to C++ via cbindgen, but that's
about it.
* Remove the `new` function from the main impl and use the slightly
less visible From conversion trait
* Make the inner Rc<Window> pub(crate) instead of pub
* Instead, provide a public as_any() accessor that the Qt backend can use
If we were to add `sixtyfps:🪟:Window` to the re_exports, then
this clashes. We might rename the former, but this is a cleaner naming
in any case.

In this case, the last line will have elipsis on the last line
when no more line can be printed
Note that the behavior is different with the Qt backend
Glutin's desire to default to srgb mysteriously creates a black window
on Windows 10 under Vmware. I tested this with many glutin apps and examples,
they all exhibit the same: black window,
working when query for srgb is turned off.
This used to work, so I suspect some change underneath on the vmware svga
driver perhaps, or Windows.
