Déclencheur de sélection pour Slint
KitSelectTrigger · Slint Kit 0.3.1
Déclencheur personnalisable partageant les interactions du sélecteur.

Essayer le composant
Télécharger le projet complet, le décompresser et lancer cargo run --locked dans son dossier. Rust 1.92+ ; Slint Kit 0.3.0 depuis crates.io. Vous pouvez aussi copier les quatre fichiers ci-dessous.
Ouvrez le déclencheur et choisissez Activity ; le contrôleur ferme la liste et publie la clé sélectionnée.

Composez son contenu non interactif et fournissez state avec un nom accessible. Relayez open-requested, dismiss, navigate et activate au contrôleur.
Il hérite de KitPressable et expose un rôle de combobox avec l’état développé. Un clic sur un sélecteur ouvert demande CloseReason.trigger-toggle ; les touches passent par KitSelectKeyboard.
Composition visuelle
Le fichier ci-dessous produit la capture. Pour les composants pilotés par un contrôleur, il montre l’état affiché sans fournir le branchement Rust. Créer un projet.
