# Dialog tabs that join their page
|
|
|
|
`Tab::show_dialog_at` adds the page-joining appearance proposed in
|
|
[WordCraft #4029](https://github.com/storytold/wordcraft/pull/4029), using the library's existing
|
|
accessible tab interaction. It suits settings and property dialogs across Craft apps.
|
|
|
|
Provide a `DialogTabStyle` with the application's colors, border, font and top corner radius.
|
|
Allocate rectangles using the application's layout and optionally `tabs::fit`; draw a baseline
|
|
before the tabs. Selected tabs use `style.page` and erase their bottom border so they join the
|
|
page. Use `style.border` for the baseline centered on the bottom edge; the selected cover extends
|
|
half its width below the interaction rectangle. Other sides and text retain their original clip.
|
|
The page should start at the tabs' bottom edge and use the same fill.
|
|
|
|
```rust
|
|
let response = craft_ui::tabs::Tab::new(stable_id, localized_label, selected)
|
|
.show_dialog_at(ui, rect, &style);
|
|
if response.clicked() {
|
|
// Update the application's selected page.
|
|
}
|
|
```
|
|
|
|
IDs must remain stable independently of translated labels. Selection, overflow, arrow-key
|
|
navigation and page content remain caller-owned. The underlying `Tab` supplies accessibility,
|
|
keyboard focus/activation, drag response and disabled behavior. Text clips to its rectangle;
|
|
invalid stroke widths become zero and invalid font sizes use 12 points. No app assets or theme
|
|
are bundled, and consumer migration is separate.
