Credit goes to @Iain-dono for implementing the actual library.
This fork aims to provide documentation and further development if necessary.
First, create your context type and your tab widget:
use egui::{Frame, Ui, style::Margin};
use egui_dock::Tab;
struct MyContext;
struct MyTab {
text: String,
}
impl MyTab {
fn new(text: impl ToString) -> Self {
Self {
text: text.to_string(),
}
}
}
impl Tab<MyContext> for MyTab {
fn title(&self) -> &str {
&self.title
}
fn ui(&mut self, ui: &mut Ui, _ctx: &mut MyContext) {
let margin = Margin::same(4.0);
Frame::none().inner_margin(margin).show(ui, |ui| {
ui.label(&self.text);
});
}
}
Then construct the initial tree using your tab widget:
use egui_dock::{NodeIndex, Tree};
let tab1 = Box::new(MyTab::new("Tab 1"));
let tab2 = Box::new(MyTab::new("Tab 2"));
let tab3 = Box::new(MyTab::new("Tab 3"));
let tab4 = Box::new(MyTab::new("Tab 4"));
let tab5 = Box::new(MyTab::new("Tab 5"));
let mut tree = Tree::new(vec![tab1, tab2]);
// You can modify the tree in runtime
let [a, b] = tree.split_left(NodeIndex::root(), 0.3, vec![tab3]);
let [_, _] = tree.split_below(a, 0.7, vec![tab4]);
let [_, _] = tree.split_below(b, 0.5, vec![tab5]);
Finally, you can show the tree.
let id = ui.id();
egui_dock::show(&mut ui, id, style, tree, context);
