I have a few questions about the context menu of nodes, and also related to editing text in nodes.

Based on the documentation at this link (https://www.mindfusion.eu/onlinehelp/xamarin.diagram/index.htm), I can prevent a user from editing the text of a node by handling the NodeTextEditing event on a diagram object. However, beyond that piece of information, no other information is provided. I've gone ahead and implemented an event handler, but it isn't clear on exactly how to implement the event handler so to prevent text editing.

My intuition would be to set a flag or return some boolean value to the caller, but the function doesn't have a return value, and there isn't an obvious flag to set anywhere. Any help in this regard would be appreciated.

Next question: is there a way to customize the context menu itself? Right now when I do a "long press" on a node, the context menu pops up as 3 icons: one to the left (a text editing icon), one above the node (a trash/delete icon), and one to the right (a paperclip icon - I haven't tested what it does). I'd like to customize what icons show up there, or maybe even have a dialog pop up or a new screen slide in when the user tries to open the context menu.

Edited:

New build here removes the default green background from editor:
https://www.nuget.org/packages/MindFusion.Diagramming.Maui/

You can now customize the color through Xaml style:

<ContentPage.Resources>
	<ResourceDictionary>
		<Style TargetType="diag:TextEditor">
			<Setter Property="BackgroundColor" Value="Yellow" />
			<Setter Property="TextColor" Value="Blue" />
		</Style>
	</ResourceDictionary>
</ContentPage.Resources>
 

We've also implemented EnterInplaceEditMode / LeaveInplaceEditMode events from our other platforms (https://www.mindfusion.eu/onlinehelp/wpfdiagram/E_MindFusion_Diagramming_Wpf_Dia...) allowing for another extension point:

diagram.EnterInplaceEditMode += OnEnterInplaceEditMode;

void OnEnterInplaceEditMode(object sender, InPlaceEditEventArgs e)
{
	e.TextEditor.BackgroundColor = Colors.Red;
}
