array of buttons in setup
Mar 19^th, 2010, 3:48am

hi guys

i have this array in my setup:
Code:


   volumeBar = new button[] {
	new button(80,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(120,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(160,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(200,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(240,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(280,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(320,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(360,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(400,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(440,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(480,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(520,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(560,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(600,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(640,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(680,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(720,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(760,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(800,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(840,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(880,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(920,hoogte,"volumeUit.png", "volumeAan.png", 50),
	new button(960,hoogte,"volumeUit.png", "volumeAan.png", 50),
    };

obviously this is very redundant.

although i can expand arrays with ints, strings,... i'm kind of stuck with this one.

i want it to be something like:
Code:


volumeBar = new button[] {
for(int i=0;i<maxButtons;i++){
new button(80+i,hoogte,"volumeUit.png", "volumeAan.png", 50),
}
 }

have you tried the following?
Code:


// define an array of buttons, in your case this array has a 
// length of 23 buttons 

volumeBar = new button[23];

// create a loop which loops from 0 to 22 and fill the 
// array with your buttons. 
// the value of the first parameter of the button 
//constructor will be set according to the value of i. 
// (here: 80, 120, etc.)

for(int i=0;i<23;i++) {
  button[i] = new button(80 + (i*40),hoogte,"volumeUit.png", "volumeAan.png", 50);
}

thx this worked! (with a slight modification).

somtimes simple solutions lay very far away if you've been staring at the screen all day.

for the people interested in the solution:
Code:

    volumeBar = new button[23];

    for(int i=0;i<23;i++) {
    volumeBar[i] = new button(80 + (i*40),hoogte,"volumeUit.png", "volumeAan.png", 50);
}
