Detecting mouse clicks on drawing objects

[Gorkhaan]

Hi,

I do have a way to do this, but I was wondering if there a better, simpler way to do this?
Basically I wish to turn a FixedText into a switch button. To do that I need mouseclick event, then a way to check if the cursor has clicked on the drawing object.
alertStatusSwitch flips between true/false

The magic happens here:

Cursor tfCursor = tfAlertStatus.GetCursor(this.ChartControl, this.ChartPanel, this.ChartPanel.Scales[0], cursorPoint);

If the cursor clicked on the drawing object, then it will return a cursor, otherwise it returns NULL.
Since the indicator creates this TextFixed drawing object, is there a better way to detect clicks on this drawing object?

Thanks in advance.


Here is my code:

protected override void OnStateChange()
{
    if (State == State.SetDefaults)
    {
        // OMMITTED //
    }
    else if (State == State.Configure)
    {
        alertStatusSwitch = true;
        tfAlertStatus = Draw.TextFixed(// OMMITTED //);
        tfAlertStatus.YPixelOffset = ChartAlertStatusYPixelOffset;
        if (ChartControl != null) {
            ChartControl.MouseLeftButtonUp += MouseClicked;
        }
    }
    else if (State == State.Terminated) {
        if (ChartControl != null) {
            ChartControl.MouseLeftButtonUp -= MouseClicked;
        }
    }
}

protected void MouseClicked(object sender, MouseButtonEventArgs e)
{
    Point cursorPoint = this.ChartControl.MouseDownPoint;
    Cursor tfCursor = tfAlertStatus.GetCursor(this.ChartControl, this.ChartPanel, this.ChartPanel.Scales[0], cursorPoint);
    if (tfCursor != null) {
        if (alertStatusSwitch) {
            tfAlertStatus = Draw.TextFixed(// OMMITTED //);
            tfAlertStatus.YPixelOffset = ChartAlertStatusYPixelOffset;
            alertStatusSwitch = false;
            ForceRefresh();
        } else {
            tfAlertStatus = Draw.TextFixed(// OMMITTED //);
            tfAlertStatus.YPixelOffset = ChartAlertStatusYPixelOffset;
            alertStatusSwitch = true;
            ForceRefresh();
        }
    }
}

Hello Gorkhaan,

Thanks for your post.

I think the easy thing to do would be to add a button to the chart instead. Drawing Objects are also intended to be moved when they are selected (TextFixed is an exception,) so attempting to wire into the Drawing Tools Mouse events wouldn't be advised.

You can see an example that implements buttons below. If that is not a more elegant solution for you, then you may wish to proceed with what you have.
