Issue with buttons on touch screen

[sriranjanr]

There is a problem with buttons on touch screen. I need to double press the button to make it work. I followed the guidelines in #34 and recompiled the library but now when I press a button it remains in the pressed state and deactivates all the UI as the button pressed does not get released.

I think the events are not getting updated after the press action. And since the following code is creating error.
if ( cp5.blockDraw == false ) {
if ( cp5.isAndroid ) {
mouseEvent( cp5.papplet.mouseX , cp5.papplet.mouseY , cp5.papplet.mousePressed );
} else {
} else if ( !cp5.isTouch ) {
updateEvents( );
}

This might be the problem.

Hi @sriranjanr, did you ever arrive at a solution to this problem (FYI @delaneyheileman)?

import controlP5.*;

ControlP5 cp5;
Button button;
color bgColor;

void setup() {
size(400, 400);
noCursor();
cp5 = new ControlP5(this);

button = cp5.addButton("button")
.setPosition(100, 100)
.setSize(100, 50)
.setLabel("Press Me");

bgColor = color(255);
}

void draw() {
background(bgColor);
}

void mousePressed() {
ControllerInterface<?> c = cp5.getController("button");
if (c instanceof Button) {
Button b = (Button) c;
if (mouseX > b.getPosition()[0] && mouseX < b.getPosition()[0] + b.getWidth() &&
mouseY > b.getPosition()[1] && mouseY < b.getPosition()[1] + b.getHeight()) {
bgColor = color(random(255), random(255), random(255));
}
}
}
