Modification des nœuds sur place
Pivotick fournit une couche d'édition, pas seulement une visionneuse. Double-cliquez sur un nœud pour ouvrir son modal d'édition ; onBeforeNodeEditCommit est votre crochet de validation/veto (retournez false pour rejeter une mauvaise modification et garder le modal ouvert), et onNodeEditCancel se déclenche lorsque l'utilisateur recule.
Double-cliquez sur Alice et modifiez un champ. Effacez le nom et essayez de sauvegarder – la validation est refusée. Le Edit Graph → Edit de la barre d'outils ouvre le même modal.
js
// Editing needs the full UI mode — the default 'viewer' is read-only. Double-click
// opens the built-in edit modal; the two commit hooks below validate and observe it.
const options = {
// Off: `full` mode brings a minimap and the data dock, and this card is about
// neither (see the Minimap and Data table cards for those).
UI: { mode: 'full', minimap: false, table: false },
callbacks: {
// Open the edit modal on double-click (the toolbar's Edit Graph → Edit does
// the same). onNodeEdit(session) also lets you return a fully custom body.
onNodeDbclick: (event, node) => graph.editing.openNodeSession(node),
// Validation / veto hook — return false to reject the commit and keep the
// modal open. Here we refuse an empty name.
onBeforeNodeEditCommit: ({ previousData, nextData }) => {
if (!nextData.label || !String(nextData.label).trim()) {
graph.notifier.warning('Name required', 'A node must keep a name.')
return false
}
graph.notifier.success('Node updated', `${previousData.label} → ${nextData.label}`)
return true
},
// Fires when the user cancels the edit.
onNodeEditCancel: (node) => graph.notifier.info('Edit cancelled', node.getData().label)
}
