Ref UITableView API:
https://developer.apple.com/documentation/uikit/uitableviewdatasource
## Changes
- Added some section related API to `ListDelegeate` and
`DropdownDelegate` with default implement, so if you don't need section
that you can just keep the default.
- Added `sections_count` method to get the number of sections, default
is 1.
- Added `render_section_header` for special the section header by if
needed, default return None.
- Added `render_section_footer` for special the section footer by if
needed, default return None.
## Break Changes
- The `DropdownState` have change new method to use IndexPath type:
```diff
- DropdownState::new(vec![], Some(1), window, cx);
+ DropdownState::new(vec![], Some(IndexPath::new(1)), window, cx);
```
- The `ListDelegeate`, `DropdownDelegate` has changed API:
- The `ix` are change from `usize` to `IndexPath`.
```diff
- fn render_item(&self, ix: usize, window: &mut Window, cx: &mut
Context<List<Self>>) -> Option<Self::Item>
+ fn render_item(&self, ix: IndexPath, window: &mut Window, cx: &mut
Context<List<Self>>) -> Option<Self::Item>
- fn set_selected_index(&mut self, ix: Option<usize>, window: &mut
Window, cx: &mut Context<List<Self>>)
+ fn set_selected_index(&mut self, ix: Option<IndexPath>, window: &mut
Window, cx: &mut Context<List<Self>>)
```
- The `items_count` method have added `section` argument to support list
section.
```diff
- fn items_count(&self, cx: &App) -> usize
+ fn items_count(&self, section: usize, cx: &App) -> usize
```
- The `can_load_more` method has renamed to `is_eof` in `ListDelegate`
and `TableDelegate`.
```diff
- fn can_load_more(&self, cx: &App) -> bool
+ fn is_eof(&self, cx: &App) -> bool
```
- The `can_search` method has renamed to `searchable` in `ListDelegate`.
```diff
- fn can_search(&self) -> bool
+ fn searchable(&self) -> bool
```

## Break Changes
- The `Scrollbar` has been removed `entity_id` and `scroll_size`
argument from new method, it will get that value from `scroll_handle`.
- There still have a `scroll_size` optional method, if you want to give
your own.
- Also changed the `scroll_state`, `scroll_handle` to receive a ref.
```diff
- Scrollbar::vertical(entity_id, scroll_state, scroll_handle, scroll_size);
+ Scrollbar::vertical(&scroll_state, &scroll_handle);
+ Scrollbar::vertical(&scroll_state, &scroll_handle).scroll_size(scroll_size);
```
## Changes
This PR unifies icon parameter types in UI components:
- Changed `ListItem.check_icon` parameter type from `IconName` to `impl
Into<Icon>`
- Changed `Dropdown.icon` parameter type from `impl Into<IconName>` to
`impl Into<Icon>`
- Updated related rendering logic
## Impact
- **API Consistency**: All components now accept the same icon parameter
type
- **Backward Compatible**: Existing code using `IconName` continues to
work
- **Enhanced Flexibility**: Components can now accept custom `Icon`
instances directly
## Break Changes
- input: Now the `text` method `Input` changed return type from
`SharedString` to `&SharedString`.
- list: Remove `set_query` and `query` method from `List`, you can use
`query_input` to instead.
- Add `loading` method to `ListDelegate` and `TableDelegate` to control
loading view display.
## Break Changes
- Remove `loading`, `set_loading` method from List and Table, use
`loading` method in delegate instead.
- Add `mix` method to mix two color.
- Export `ui::theme::*` to crate root, before `use
ui:theme::ActiveTheme` to `use ui::ActiveTheme`.
## Break Changes
- Moved `ui::theme::Colorize` to `ui::Colorize`.
- Merged `ColorExt` to `Colorize`.
- Renamed `to_hex_string` to `to_hex`, `parse_hex_string` to
`parse_hex`.
## Break changes
- Renamed list `enable_scrollbar` to `scrollbar_visible` to match with
the table API.
