Summary

How can I display the Radius of a circle in a tooltip while CmdCircle is active.

Solution

In a form place vdFramedControl and a simple button. Then check the code below :

private void Form1_Load(object sender, EventArgs e)
{
       vdFramedControl1.BaseControl.ActiveDocument.OnActionJobLoop += new VectorDraw.Professional.vdObjects.vdDocument.ActionJobLoopEventHandler(ActiveDocument_OnActionJobLoop);
}

private bool CmdCircleStarted = false;
private void button1_Click(object sender, EventArgs e)
{
       CmdCircleStarted = true;
       vdFramedControl1.BaseControl.ActiveDocument.CommandAction.CmdCircle("USER", "USER");
       vdFramedControl1.BaseControl.ActiveDocument.ToolTipText = "";
       CmdCircleStarted = false;
}

void ActiveDocument_OnActionJobLoop(object sender, object action, ref bool cancel)
{
      if (!CmdCircleStarted) return;
      VectorDraw.Professional.CommandActions.ActionCircle act = action as VectorDraw.Professional.CommandActions.ActionCircle; 
      if (act == null) return;
      VectorDraw.Professional.vdFigures.vdCircle circle = act.Entity as VectorDraw.Professional.vdFigures.vdCircle;
      if (circle == null) return;
      vdFramedControl1.BaseControl.ActiveDocument.ToolTipText = "Radius: " + vdFramedControl1.BaseControl.ActiveDocument.lunits.FormatLength (circle.Radius);
}
