In this case, need a flag to set the input is focused. #[derive(Clone, Default, PartialEq, Eq, Deserialize, Serialize)]
pub struct AddWindow {
name: String,
autofocus: bool,
}
impl Window for AddWindow {
fn show(
&mut self,
data: Option<Message>,
) {
// first rendered
if let Some(Message::Normal) = data {
self.autofocus = true;
}
egui::Window::new("the window")
.resizable(false)
.default_width(280.0)
.open(true)
.show(ctx, |ui| self.ui(ui));
}
}
impl View for AddWindow {
fn ui(&mut self, ui: &mut egui::Ui) {
ui.horizontal(|ui| {
ui.add_sized((50., 24.), egui::Label::new("Name:"));
let resp =
ui.add(egui::TextEdit::singleline(&mut self.name).hint_text("Write folder name"));
// turn off `autofocus`
if self.autofocus {
self.autofocus = false;
ui.memory().request_focus(resp.id);
}
});
}

Any updates here, is this something you do manually or is there an egui way now? |
I, too, am interested in this. |

Uh oh!
There was an error while loading. Please reload this page.
I'm playing with dialog prompts in egui.
It would be nice to be able to request that a widget receives "default focus" upon appearing, so the user can just press enter to activate the default button without pressing tab first.
(e.g. when a window first appears, focus the "ok" button)
I tried this pattern, which works ok, though there's weirdness (see the end of this comment).
A method like
ui.memory().default_focus(widget.id)that sets focus only if it's not already set, may work well as a starting point for this.I think one alternative is tracking a "first open" flag somewhere in my own code for each UI container that cares about default focus, however that may not handle something like a multi-page wizard where the contents change without creating a new container.
Weirdness with my memory approach:
