It might be possible by automatically selecting the arrow nodes first. If moving the nodes too is ok for you, I can create some example to show how to do that.

At this time the control uses only the left button for user interaction. We can add a new property to the FlowChart that will let you use the right button too.

Hi,

Here is how that can be done by selecting the boxes and moving the multiple-selection:

private void Form1_Load(object sender, System.EventArgs e)
{
  fc.AllowSplitArrows = false;
  fc.ModificationStart = ModificationStyle.AutoHandles;
  fc.CustomBehavior = new ArrowMoveBehavior(fc);
}

class ArrowMoveBehavior : FlowChartBehavior
{
  public ArrowMoveBehavior(FlowChart flowChart) : base(flowChart) {}

  public override InteractionState StartDraw(PointF point)
  {
    Arrow arrow = FlowChart.GetArrowAt(point, 1, true);
    int selectionHandle = -1;
    if (arrow != null && !arrow.HitTestHandle(point, ref selectionHandle))
    {
     FlowChart.Selection.AddObject(arrow.Origin);
     FlowChart.Selection.AddObject(arrow.Destination);
     return new InteractionState(FlowChart.Selection, 8, Action.Modify);
    }
    return base.StartDraw(point);
  }
}
 

Now dragging a control point will work as before. If you drag any other point of the arrow, the adjacent boxes will be selected, and the arrow shape will be preserved while the whole selection is moved. You might keep a boolean flag set and deselect the boxes upon MouseUp if you don't want them selected after the modification.

I hope that helps,

Hi Thorsten,

We are currently preparing a new version of the control for release, and are quite behind schedule. We'll add the new property when we are ready with the release and will upload the updated dlls here.

Stoyan

That will be a small change so we'll do it on the day after the release, which should happen at some time next week.

It seems that FlowChartBehavior has been made public only recently. Try that with these dlls:

https://mindfusion.org/_temp/v422.zip

There are some API changes though - you will have to change all "MindFusion.FlowChartX" namespace references to "MindFusion.Diagramming.WinForms". In addition, these dlls are from our daily build and might not be very stable.

Stoyo,

how is the release doing?

Do you have time to add the RMB property?
