SetEnabled(DockManagerEventGroups,Boolean) メソッド

指定されたグループに関連付けられたすべてのイベントを有効または無効に設定します。

Public Overloads Sub SetEnabled( _

パラメータ

group
Enabled 状態を設定するイベントを格納している DockManagerEventGroups の 1 つ。
enabled
グループ内の各イベントに割り当てられる状態。グループのすべてのイベントについて有効にする場合はTrueを指定し、無効にする場合はFalseを指定します。
解説

EventManager はコントロールのイベントを選択的に有効または無効にするために使用します。UltraDockManager のイベントは、関連するイベントの集まりを簡単に有効または無効にできるように、グループに分類されています。このメソッドを使用すると、グループ内のすべてのイベントの Enabled 状態を一度に設定できます。

注意 イベントの処理が完了する前にイベントを無効にすることは避けてください。まだ処理中のイベントを無効にした場合、予期しない結果を招くおそれがあります。イベントを無効にするときは、その前にそのイベントが現在コードを処理中かどうかを InProgress(DockManagerEventIds) メソッドでチェックしてください。
