Hey all,

Im new to processing and im trying to write a program that will change menus when you click on the rectangle.

Here is the code I have now:

void setup() {
size(480,800);
}
void draw() {
mainmen();
}
void mainmen() {
background(255,255,255); //Set BG to white
//Draw first button
fill(255,255,255);
stroke(0,0,0);
rect(20,20,200,200);
if(mouseX > 20 && mouseX < 220 && mouseY > 20 && mouseY < 220 && mouseClicked() == true) {
fill(0,0,0);
stroke(0,0,0);
rect(20,20,200,200);
fanmen();
}
}

The code goes on with a function for fanmen but thats the thing, fanmen only appears as long as the mouse is being pressed, How can I have it switch to the function completely, even when the mouse is released?

Thanks for the help,

Hamish

this could work :

int click= 0;
void setup() {
size(480, 800);
}

void draw() {

if (click==1) {
    fill(0, 0, 0);
    stroke(0, 0, 0);
    rect(20, 20, 200, 200);
    //    fanmen();
}
else {
    mainmen();
}
}

void mainmen() {
background(255, 255, 255); //Set BG to white
//Draw first button
fill(255, 255, 255);
stroke(0, 0, 0);
rect(20, 20, 200, 200);
}

void mousePressed()
{
if (mouseX > 20 && mouseX < 220 && mouseY > 20 && mouseY < 220 && click ==1)
    click =0;
else {
    if (mouseX > 20 && mouseX < 220 && mouseY > 20 && mouseY < 220 && click ==0)
      click =1;
}
}

you can search for GUI library which gives you a lot of cool buttons-slides…
G4P or controlP5

Thats exactly what I need, Thanks! :D

Unfortunately, I cant use any extra libraries because im only prototyping the GUI for an Arduino controlled LCD so I need to keep everything as basic as possible, saying that, what you have given me is perfect.

Thanks again :)
