* use new focus subsystem in widgets.EditField
* always eat the enter key if we have an on_submit
* add modal attribute
* give EditFields a default height of 1
so they can be autoarranged
* fix wrong `Label.frame_body.x2` value
`update_scroll_inset` might change `frame_inset`, i.e. we need to `computeFrame` with the new values.
* add tests for Label
* add missing `local`, remove code in comments
* move `TestFramedScreen` outside test functions
* WIP: add scroll icons to Label widget
It's an opt-out. The icons are rendered in the right-most column of the 1st and last row. They are only rendered when text can actually be scrolled in the corresponding direction.
WIP: Currently, the icons might overlay text characters, there is no mechanism preventing it
* gui.lua: expose the `parse_inset()` function
* refactor Label's scroll icon code
* since `render_scroll_icons` only works with a label, it's now a class function
* `update_scroll_inset` ensures `frame_inset.r` or `.l` is at least 1, according to `show_scroll_icons`
* `show_scroll_icons` has 4 possible values: `false` for no icons, `left` for icons on the first column on the left (also ensuring `frame_inset.l >= 1`), `right` - last column on the right, `DEFAULT_NIL` - same as `right` if text height greater than `frame_body.height`, else same as `false`.
* make `render_scroll_icons` always draw icons
The check now happens in `onRenderFrame`
* draw frame's background
calling `Label.super.onRenderFrame(self, dc, rect)` makes frame's background invisible for some reason
* remove trailing spaces
* fix scroll icons placed far above/below text
With `Label.frame_inset = 1` the text could be vertically centered with plenty of space below and above,
but not all rendered. Before this change, the scroll icons would be at the very top and bottom of the frame
instead of near the first and last rendered text line.
* always `update_scroll_inset` to react to resized window
* draw scroll icons next to text
* update `Lua API.rst` with new `Label` parameters
* move comment separator up
This way every scroll related parameter is in one group
* list default values for new parameters in docs
* add missing description of `Label.scroll_keys`
Current logic is because @myk002 fixed it so label would allow other widgets control when label(s) are present. However that breaks label key detection for default scroll keys. This can be worked around by setting scrollkeys to empty.
TBH: label is quite complicated and used everwhere so i'm reluctant to touch it and would love for someone to look over if i'm correct.
