Applet template

[Archibald]

Can someone tell me how to change this template to get mouseX, mouseY, left mousebutton (as variables)?

(I started learning Java like 4 days ago and I got a headache when I saw how many possible methods to obtain mouse position there are )

Well, it kind of depends on what you want exactly, that's why there are so many methods

Anyway, you should probably check out these two tutorials:

I need the simpliest one, just filling the ??? parts.

public boolean handleEvent(Event e) {             switch (e.id) {                   case Event.KEY_PRESS:                   case Event.KEY_ACTION:                       // key pressed                      break;                   case Event.KEY_RELEASE:                       // key released                      break;                   case Event.MOUSE_DOWN:                       // mouse button pressed mouseButtonState=???;                       break;                   case Event.MOUSE_UP:                       // mouse button released mouseButtonState=???;                       break;                   case Event.MOUSE_MOVE:  mouseX=???; mouseY=???;                       break;                   case Event.MOUSE_DRAG:                       break;              }              return false;    }

The event that is passed to the handler has all the information, so in case of the movement:

1   2   3   4   5   6

... case Event.MOUSE_MOVE:     mouseX=e.getX();     mouseY=e.getY();     break; ...

And in the case of the mouse_down and mouse_up, e.getButton() returns an int corresponding to the mousebutton the event applies to, so:

1   2   3   4   5   6   7

... case Event.MOUSE_DOWN:     if (e.getButton() == MouseEvent.BUTTON1) {         mouseButtonState="down";     }     break; ...

and similar for Event.MOUSE_UP

I'm sorry, apparently the x and y values are public. You don't need to use getters but you can use this:

1	mouseX=e.x;

this is all deprecated code by the way. In case of the 4k competition you can still use this (because it requires less code this way) but in other applications I recommend using mouseListener and mouseMotionListener.

EDIT:
The code I gave for the button doesn't work with the old events either. In order to differentiate between mouse buttons you need to check e.modifiers.

1   2   3   4

case Event.MOUSE_DOWN:     if (e.modifiers == 0) //left button    if (e.modifiers == Event.ALT_MASK // middle button    if (e.modifiers == Event.META_MASK // right button

Unfortunately, this method counts pressing the left button while holding the alt key as pressing the middle mouse button. If that's a problem, you'll need to use the newer listeners.

Works, thanks (maybe by some miracle I will finish it before the deadline )
