I found the answer by myself.

private NDrawingView diagramView = null;
private NDiagramCommander commander = null;

diagramView = new NDrawingView ()
commander = new NDiagramCommander ()

commander.View = diagramView;


...

If i now want to put a "ZoomIn Button" on my GUI, i just send the command
to the diagram in my OnClick for my Button:


public void ZoomIn()
{
NZoomInCommand command = new NZoomInCommand();
commander.Commands.Add(command);
command.Execute();
}

The good is, all the Undo and Redo functions built in the diagram component works as well.

Some more Wrapper-Methods i build:


public void ZoomTo(ushort percent)
{
NZoomPercentCommand command = new NZoomPercentCommand();
commander.Commands.Add(command);
command.Execute(percent.ToString());
}


public void ZoomWidth()
{
NZoomPercentCommand command = new NZoomPercentCommand();
commander.Commands.Add(command);
command.Execute("Width");
}


public void ZoomHeight()
{
NZoomPercentCommand command = new NZoomPercentCommand();
commander.Commands.Add(command);
command.Execute("Height");
}

public void ZoomFit()
{
NZoomPercentCommand command = new NZoomPercentCommand();
commander.Commands.Add(command);
command.Execute("Fit");
}

public void Undo()
{
NUndoCommand command = new NUndoCommand();
commander.Commands.Add(command);
command.Execute();
}

public void Redo()
{
NRedoCommand command = new NRedoCommand();
commander.Commands.Add(command);
command.Execute();
}

public void AlignRight()
{
NAlignRightsCommand command = new NAlignRightsCommand();
commander.Commands.Add(command);
command.Execute();
}

And so on ...

Kind Regards, Dieter

I want to programmatically do all commands without your command bar,
but i don't want to use your command bar. We are using other
GUI controls.

I am searching for something like this:

NZoomInCommand command = new NZoomInCommand();
myDigram.Commands.Execute(command);

Sorry i can not find it in your documentation or sample application.

Kind Regards, Dieter
