The track symbol is now optional, simplifying composition with other
widgets.
BREAKING_CHANGE: The `track_symbol` needs to be set in the following way
now:
```
let scrollbar = Scrollbar::default().track_symbol(Some("-"));
```
The symbols and sets are moved from `widgets::scrollbar` to
`symbols::scrollbar`. This makes it consistent with the other symbol
sets and allows us to make the scrollbar module private rather than
re-exporting it.
BREAKING CHANGE: The symbols are now in the `symbols` module. To update
your code, add an import for `ratatui:🔣:scrollbar::*` (or the
specific symbols you need). The scrollbar module is no longer public. To
update your code, remove any `widgets::scrollbar` imports and replace it
with `ratatui::widgets::Scrollbar`.
This commit adds a readme to the examples directory with gifs of each
example. This should make it easier to see what each example does
without having to run it.
I modified the examples to fit better in the gifs. Mostly this was just
removing the margins, but for the block example I cleaned up the code a
bit to make it more readable and changed it so the background bug is not
triggered.
For the table example, the combination of Min, Length, and Percent
constraints was causing the table to panic when the terminal was too
small. I changed the example to use the Max constraint instead of the
Length constraint.
The layout example now shows information about how the layout is
constrained on each block (which is now a paragraph with a block).
This helps to keep the prelude small and less likely to conflict with
other crates.
- remove widgets module from prelude as the entire module can be just as
easily imported with `use ratatui::widgets::*;`
- move prelude module into its own file
- update examples to import widgets module instead of just prelude
- added several modules to prelude to make it possible to qualify
imports that collide with other types that have similar names
Represents a scrollbar widget that renders a track, thumb and arrows
either horizontally or vertically. State is kept in ScrollbarState, and
passed as a parameter to the render function.
