ColorLine onMouseOver/onClick event?

[acastro]

Hi,

I would like to detect when the user's mouse is over a ColorLine, or when click it to show a tooltip. But I only found EndDragLine and DragLine, and I don't want the user move it to show the tooltip. Any Ideas?

Thanks

Hi wakeup,

Have you tried with the MouseMove event with the tool clicked method?

Code: Select all

        Steema.TeeChart.Tools.ColorLine colorline1;
        Steema.TeeChart.Tools.Annotation annotation1;

        private void InitializeChart()
        {
            tChart1.Aspect.View3D = false;

            Steema.TeeChart.Styles.Line line1 = new Steema.TeeChart.Styles.Line(tChart1.Chart);
            line1.FillSampleValues();

            colorline1 = new Steema.TeeChart.Tools.ColorLine(tChart1.Chart);
            colorline1.Axis = tChart1.Axes.Bottom;
            colorline1.Value = 10;

            annotation1 = new Steema.TeeChart.Tools.Annotation(tChart1.Chart);
            annotation1.Active = false;
            colorline1.ColorLineClickTolerance = 5;

            tChart1.MouseMove += new MouseEventHandler(tChart1_MouseMove);
        }

        void tChart1_MouseMove(object sender, MouseEventArgs e)
        {
            if /*(colorline1.Clicked(e.X, e.Y))*/ (Math.Abs(e.X - colorline1.Axis.CalcPosValue(colorline1.Value)) == colorline1.ColorLineClickTolerance)
            {
                annotation1.Text = "colorline1 value: " + colorline1.Value.ToString();
                annotation1.Top = e.Y;
                annotation1.Left = e.X;
                annotation1.Active = true;
                tChart1.Refresh();
            }
            else annotation1.Active = false;
        }

It seems that the colorline clicked method doesn't return the correct value, that's I used "(Math.Abs(e.X - colorline1.Axis.CalcPosValue(colorline1.Value)) == colorline1.ColorLineClickTolerance)" instead of it. Could you please confirm that the clicked method doesn't work as expected?

Sorry. My the type of my chart.MouseMove is EventHandler and not MouseEventHandler. So I can't get e.X, e.Y values...
What have I different? I'm woring with Visual studio 2008 and the the last version of teechart.net

Thanks

Hi wakeup,

Are you programming on C++? Here, creating the event at designtime it looks as follows:

Code: Select all

this->tChart1->MouseMove += gcnew System::Windows::Forms::MouseEventHandler(this, &Form1::tChart1_MouseMove);
//...
private: System::Void tChart1_MouseMove(System::Object^  sender, System::Windows::Forms::MouseEventArgs^  e) {
}

[acastro]

No, I'm programming in C#
thanks!

Hi wakeup,

It's strange. Have you tried the code I posted above in a new testing WinForms project (File\New\Project...\Visual C#\Windows Forms Application)?

[acastro]

Oh! Sorry. I was using the mouseOver event instead of mouseMove. Now it runs.
But it doen't run with the colorline1.Clicked condition

Hi wakeup,

Thanks, I've added it to the defect list to be fixed in future releases (TF02014736).
