mouseEvent - figure out event?

clankill3r

In a class i have:

    p.registerMethod("mouseEvent", this);

I need to know the even for the following:

public void mouseEvent(MouseEvent e){

        if (currentMode == null) return;

        // call mousePressed(), mouseClicked(), mouseDragged() etc. in currentMode
}

How do i get the event?

GoToLoop

There's no variable called currentMode in Processing's API. So I dunno what are you checking against! :@)

clankill3r

sorry currentMode is something i made. In currentMode i also have mousePressed() etc. And what i want to do is that when currentMode exist make a call like:

currentMode.mousePressed();

GoToLoop

Still very confusing. Is currentMode a PApplet reference just like p?
Why do you need both? Your concoction is still a mystery! [..]

I need to know from MouseEvent e what kind of event it is. :)

GoToLoop

This is its source code:

This might help

public class MouseHandler {
  PApplet p = null;

  public MouseHandler(PApplet papp) {
    p = papp;
    p.registerMethod("mouseEvent", this);
  }

  public void mouseEvent(MouseEvent e) {
    switch(e.getAction()) {
    case MouseEvent.PRESS:
      mousePress(e);
      break;
    case MouseEvent.RELEASE:
      mouseRelease(e);
      break;
    case MouseEvent.CLICK:
      mouseClick(e);
      break;
      // Repeat for other event types
    } 
  }

  public mousePress(MouseEvent e) { 
    // your code 
  }

  public mouseRelease(MouseEvent e) {
     // your code
  }

  public mouseClick(MouseEvent e) {
    // your code
  }
  // Add methods for other mouse events
}

GoToLoop

Seems like I'm lacking cognitive skills:
* Is MyObject() supposed to be the constructor for class MouseHandler?
* Again, the mysterious field currentMode pops up outta nowhere!

In short, my Processing v2.0.2 can't compile that!!! [..]

quark

I started calling the class MyObject and changed it to MouseHandler and forgot to change the ctor. I have now corrected that now.

True the code will not compile because of the currentMode so I have now removed that now.

Perhaps I should have said that the code wasn't tested but it was only to show how to structure a possible solution. :)

@quark, I believe your code only scratches whatever @clankill3r is brewing.
He said: "In currentMode i also have mousePressed()." Even though he's yet to tell us what type that field actually is!
So it's more complicated than we think it is. And @clankill3r expects to know how to help him out anyways!

P.S.: You use mousePress() instead of mousePressed()! ;)

quark

@GoToLoop - I agree we haven't got the full story yet.

I suspect that currentMode is an object instantiated from a class he has created, which is why I provided an outline class.

When I typed the code I used mousePress instead of mousePressed because it matches the action type, if he wants to use mousePressed instead - no problem. :)

clankill3r

Quark is right :) And thanks for the code.

I jus have different displayModes and to have interaction i want each of them to have own events. But i figured my old way is better since it gives more control. For example:

void keyPressed() {
   if (key == '1') {
       changeMode(0);
   }
    else if (key == '2') {
       changeMode(1);
   }
    else {
       currentMode.keyPressed();
    }
}
