Example of using mouse events in study?

[Shtick Hustler]

Searched the MW example studies and saw no examples of use of the following methods.

Does anyone have an example to share?

onDoubleClick()

onClick()

onWheelMoved()

 

[Spin]

I checked: nothing in my archive / the older SDK.jar's.
I'm quite surprised actually

Alas...it's time for trial and error. 🥵

There is a tiny bit about those methods in the SDK manual:

(page 31 -32)

Not sure you saw that already; simply trying to keep the sweating to a minimum

I saw the addition of these methods mentioned, but missed these specifics...thanks.

For a 1st test, I added onclick, and just had it print the Point and Int:

@Override
public boolean onClick(Point pnt, int modKey) {
    System.out.println("\n ---->onClick()");
    System.out.println(tt + " pnt = " + pnt);
    System.out.println(tt + " modKey = " + modKey);

    return super.onClick(pnt, modKey);
}

Then got this output when I clicked:

---->onClick()
         pnt = java.awt.Point[x=586,y=172]
         modKey = 0

Next step is to figure out how to translate from these Point() values into MW's time/price values, so I can tell what's been clicked on in code.

Next step is to figure out how to translate from these Point() values into MW's time/price values

Found it:

// Translates a 'real' date and value into a point on the graph.
Point2D translate(long time, double value)

Here @ DrawContext

On further research, I discovered using DrawContext is a bit of an advanced procedure. You can't just use an override function to grab a DrawContext reference. It requires creating a static class extending figures, or custom class constructors.

Here's an example from the MoonPhases study:

  private static class MoonPhase extends Figure
  {
    MoonPhase(long time, Phase p, boolean show24)
    {
      this.time = time;
      phase = p;
      SimpleDateFormat fmt = show24 ? fmt24 : fmt12;
      topLbl = new Text(fmt.format(time), TIMF_FONT, new Insets(1, 3, 1, 1), false);
      bottomLbl = new Text(fmt.format(time), TIMF_FONT, new Insets(1, 3, 1, 1), false);
    }

I don't have time to explore it at the moment; just wanted to give a heads-up to anyone who does.
