Property CommandsToBubbleUp
CommandsToBubbleUp
Gets or sets the list of commands that should bubble up to this View from unhandled SubViews or from SubViews within this View's adornments (Padding, Border, Margin). When a SubView raises a command that is not handled, and the command is in the SuperView's CommandsToBubbleUp list, the command will be invoked on the SuperView.
public IReadOnlyList<Command> CommandsToBubbleUp { get; set; }Property Value
Remarks
For SubViews inside an AdornmentView (e.g., a view in Padding or Border),
the bubble target is Parent (the owning View) rather than
SuperView. This means a view added to editor.Padding will bubble
commands directly to editor, not to the PaddingView.
Mouse-wheel forwarding pattern: A SubView can add a MouseBindings entry
(e.g., MouseBindings.Add(MouseFlags.WheeledUp, Command.ScrollUp)) without calling
AddCommand for the command. The unhandled command will fire
CommandNotBound and then bubble via TryBubbleUp(ICommandContext?, bool) to the nearest
ancestor whose CommandsToBubbleUp contains it.
Example — enable scroll command bubbling:
<pre><code class="lang-csharp">editor.CommandsToBubbleUp = [Command.ScrollUp, Command.ScrollDown];</code></pre>
Example — enable Activate bubbling for hierarchical views:
<pre><code class="lang-csharp">menuBar.CommandsToBubbleUp = [Command.Activate];</code></pre>
