We decided that their type mapping is not ready for public API yet. For
example for duration we'd like to replace the opaque i64 with another
opaque type that however has convenient conversions to
std::time::Duration or std::chrono::milliseconds. We can't use either
directly because we need ffi compatibility, in order to create an
instance in C++ and pass it to the Rust run-time.
So this hides such properties and instead produces a warning.
We support directly nested layouts, but we did not support indirect
nesting:
GridLayout {
Rectangle {
l2 := GridLayout { ... }
}
}
This patch fixes that by detecting this scenario and merging the layout
info of the element (Rectangle) and the layout inside (l2). This makes
it much easier to create re-usable components that use layouts
themselves and allows placing them in layouts.
Sometimes re-usable components need to act as containers that allow the
user to place other items inside. The component needs to be able to
control the placement of these user-provided elements. That is what the
new
$children
expression inside elements does.
This adds horizontal_alignment/vertical_alignment properties, along with
width/height to Text.
This still uses a hard-coded enumeration in the compiler, which is meant
to go away in favor of general enum support.
We were not parsing CodeBlock node from the signal handler correctly,
we wer eonly taking the first expression instead of the whole codeblock
In JS, emitting signal before the show() did not update the GLOBAL_CONTEXT
needed to emit signals defined in JS
It doesn't really make sense to have them in the API, the grid layout is
supposed to "own" the surrounding space. That can be an element and then
it should be a (0, 0) and distribute the element's width/height, or in
the future it can be a cell of a grid layout. Then there's an (x/y), but
that's implicit / hidden.
Instead of storing the "within" element that we unconditionally take the
"width" and "height" properties from, let's pass through a property
reference expression to the width/height to use. For now that's still
the layout parent's width/height, but with this it can be replaced in
the future to refer to a "virtual" property that belongs to parent cell.
