mainwindow.xamlファイルにタブコントロールがあります。起動時にアプリを実行すると、4つのタブすべてが表示されます。ユーザーが[接続]タブをダブルクリックすると、このタブのビュー全体が新しいフローティングウィンドウとしてポップアップし、ポップアップしたウィンドウをダブルクリックすると、初期状態に戻る方法はありますか?
<Grid Grid.Row="0" >
<TabControl Name="ConnectTab" Style="{DynamicResource styleBackground}" />
<tablocal:CloseableTabItem Header="Connect" />
<tablocal:CloseableTabItem Header="I2C" />
<tablocal:CloseableTabItem Header="Voltage" />
<tablocal:CloseableTabItem Header="Clock" />
</TabControl>
</Grid>
これは、タブのボタンを閉じる方法です。
private void CloseTab(object source, RoutedEventArgs args)
{
TabItem tabItem = args.Source as TabItem;
if (ConnectTab != null && ConnectTab.Items.Count > 1)
ConnectTab.Items.Remove(tabItem);
}
Closetabクラス:
public class CloseableTabItem : TabItem
{
static CloseableTabItem()
{
//This OverrideMetadata call tells the system that this element wants to provide a style that is different than its base class.
//This style is defined in themes\generic.xaml
DefaultStyleKeyProperty.OverrideMetadata(typeof(CloseableTabItem),
new FrameworkPropertyMetadata(typeof(CloseableTabItem)));
}
public static readonly RoutedEvent CloseTabEvent =
EventManager.RegisterRoutedEvent("CloseTab", RoutingStrategy.Bubble,
typeof(RoutedEventHandler), typeof(CloseableTabItem));
public event RoutedEventHandler CloseTab
{
add { AddHandler(CloseTabEvent, value); }
remove { RemoveHandler(CloseTabEvent, value); }
}
public override void OnApplyTemplate()
{
base.OnApplyTemplate();
Button closeButton = base.GetTemplateChild("PART_Close") as Button;
if (closeButton != null)
closeButton.Click += new System.Windows.RoutedEventHandler(closeButton_Click);
}
void closeButton_Click(object sender, System.Windows.RoutedEventArgs e)
{
this.RaiseEvent(new RoutedEventArgs(CloseTabEvent, this));
}
}
