Custom command with custom shape tool

Hi,

I would like to add a custom commad to the 'Tools' toolbar which enables the user to draw a custom shape. The custom shape tool works well but the custom command isn't shown. How can I do this?

public class CreateChannelCommand : NDiagramCheckButtonCommand
{
#region Member

private NCustomImageList mimageList;

#endregion

public CreateChannelCommand(): base((int) DiagramCommandRange.Tools, (int) 88888, "Channel create tool", "Channel tool")
{
try
{
mimageList = new NCustomImageList(Image.FromFile(@"C:\Temp\Prozessbildeditor\Nevron\Test\WindowsFormsApplication2\icon\gear_add.bmp"), new NSize(16, 16));
}
catch (Exception e)
{
}
}

public override string Text
{
get { return "Hello channel command"; }
}

public override bool Enabled
{
get
{
if (Commander == null || Commander.View == null)
return false;

return true;
}
}

public override bool Checked
{
get
{
if (Commander == null)
return false;

NDrawingView view = Commander.View;
if (view == null)
return false;

return view.Controller.Tools.IsToolEnabled("CreateChannelCommand");
}
}

public override void Execute()
{
if (Commander == null)
return;

NDrawingView view = Commander.View;
if (view == null)
return;

view.Controller.Tools.SingleEnableTool("CreateChannelCommand");
}

public override string TooltipText
{
get
{
return "Chhaannel";
}
set
{
base.TooltipText = value;
}
}

public override bool GetImageInfo(out NCustomImageList imageList, out int imageIndex)
{
imageList = this.mimageList;
imageIndex = 0;
return true;
// return base.GetImageInfo(out imageList, out imageIndex);
}




}//Within my Form1_Load
var cmd = new CreateChannelCommand();
nDiagramCommandBarsManager1.Commander.Commands.Add(cmd);
nDiagramCommandBarsManager1.Recreate();

NCreateShapeTool createChannelShapeTool = new NCreateShapeTool();
createChannelShapeTool.Name = "CreateChannelTool";
createChannelShapeTool.Shape = new MyChannelShape();

nDrawingView1.Controller.Tools.Add(createChannelShapeTool);
nDrawingView1.Controller.Tools.EnableTools(new[] { "CreateChannelTool" });

Hi Uli,

First you will need to change the value of the second parameter in the CreateChanelCommand constructor from (int)8888 to (int)DiagramCommand.LastCommandId + 1

You will also need to create your custom toolbars builder class similar to the following:


public class MyNDiagramToolBarsBuilder : NDiagramToolbarsBuilder
{
    public override NDockingToolbar[] BuildToolbars()
    {
        ArrayList toolbars = new ArrayList(base.BuildToolbars());
        int commandId = (int)DiagramCommand.LastCommandId + 1;
        NCommand command = CreateCommand(commandId, false);
        for (int i = 0; i < toolbars.Count; i++)
        {
            NToolbar toolbar = toolbars[i] as NToolbar;
            if(toolbars == null)
            {
                continue;
            }
            if (toolbar.Text == "Tools")
            {
                toolbar.Commands.Add(command);
            }
        }
        return (NDockingToolbar[])toolbars.ToArray(typeof(NDockingToolbar));
    }

    public override void Reset()
    {
        base.Reset();

        customCommandIds = new ArrayList();
        customCommandIds.Add((int)DiagramCommand.LastCommandId + 1);
    }

    private ArrayList customCommandIds;
}


Then you will need to set an instance of the class above to NDiagramCommandBarsManager.ToolbarsBuilder property.

I hope this helps.

works like a charm. Thank you for your quick response.
