G4P -- Simulating button click through two-way serial communication

in Contributed Library Questions • 2 months ago

Hey folks,

I am trying to simulate a button click after either a certain amount of time without me having to manually click the button, or once my Arduino sends back serial data.

Here's my code!

import g4p_controls.*; //GUI Library
import processing.serial.*; //Serial Library
PImage img; //TCAP Image
boolean onbutton1 = false; //button starts as OFF
Serial myPort; //New serial
public void setup(){
size(996, 679, JAVA2D);
createGUI();
customGUI();
img = loadImage("Background.JPG"); // image
myPort = new Serial(this, Serial.list()[1], 9600);
}
public void draw(){
background(img);
if(millis()>30000) //WHERE I'M HAVING DIFFICULTY!
{ // I want to have the button actuate without clicking
onbutton1_click1(1,444045); // after 30 seconds using the code from the GUI tab below
}
}
// Use this method to add additional statements
// to customise the GUI controls
public void customGUI(){
}

In GUI Tab:

public void button1_click1(GImageButton source, GEvent event) { //_CODE_:valve1:444045:
println("imgButton2 - GImageButton event occured " + System.currentTimeMillis()%10000000 );
onbutton1=!onbutton1;
myPort.write(17);
} //_CODE_:valve1:444045: //<------ I'm using this code because I believe it's
// got something to do with what I want!

My problem isn't on the Arduino side, but here in Processing. When I try the above, I get an error:

"The method button1_click1(GImageButton, GEvent) in "MyProject" is not applicable for the arguments (int, int)"

Any ideas on what I'm doing wrong?

Thanks a lot for the help!

Why not skip the simulate the mouse button event?
for example, if you change the condition into this:

if(millis()>30000)
{
onbutton1=!onbutton1;
myPort.write(17);
}

Then you reached your goal. And the user can still press the button if he/she like.
The only thing you must not forget, is that when millis() is greater than 30000, that it only triggers once. Because Processing will keeps sending that the button is pressed after 30000 milliseconds.

First of all an explanation of the event handler method

public void button1_click1(GImageButton source, GEvent event) { //_CODE_:valve1:444045:
println("imgButton2 - GImageButton event occured " + System.currentTimeMillis()%10000000 );
onbutton1=!onbutton1;
myPort.write(17);
} //_CODE_:valve1:444045:

This the comments
//_CODE_:valve1:444045:
have been created by the GUI Builder tool which uses them to identify the start and end of an event handler. In fact the numbers are simply randomly generated 6 digit unique number. What is important is that they are at the end-of-the-line and all user event code are on their own lines inside the method.

"The method button1_click1( GImageButton, GEvent) in "MyProject" is not applicable for the arguments (int, int)"

This method requires a GImageButton and a GEvent object so will not work with 2 int(s). This event handler is associated with a GImageButton called valve1 so to execute this handler you need to use

button1_click1(valve1, GEvent.CLICKED) ;

Merging this with your draw method code you get

public void draw(){
background(img);
if(millis()>30000) {
button1_click1(valve1, GEvent.CLICKED);
}
}

BEWARE - this will call the button1_click1 method every frame (~60 times a second) after 30 seconds have elapsed.
