G4P - GSlider

gmellocmr

If i have a program with more than one window, how can i show the slider in just one of those windows?
I tried to call it inside a PGraphics, but the constructor requires a PApplet. If i use this, the slider appears on all of the windows... I tried too to call the slider only when i'm in the windown i want, but slider doesn't work if created in draw(), only in setup()...
Any thoughts? Thanks ;)

The easiest way to create GUIs with G4P is to use the GUI Builder tool (Tools | Add Tool menu option) but if you have already created your sketch then the code below shows how to create a second window and add a slider to it.

import g4p_controls.*;

// Variable declarations 
GWindow window1;
GSlider slider1; 


public void setup(){
  size(480, 320, JAVA2D);
  createGUI();

}

public void draw(){
  background(230);

}

// Create all the GUI controls. 
public void createGUI(){
  G4P.messagesEnabled(false);
  G4P.setGlobalColorScheme(GCScheme.BLUE_SCHEME);
  G4P.setCursor(ARROW);
  window1 = new GWindow(this, "Window title", 0, 0, 240, 120, false, JAVA2D);
  window1.addDrawHandler(this, "win_draw1");
  slider1 = new GSlider(window1.papplet, 70, 40, 100, 40, 10.0);
  slider1.setLimits(0.5, 0.0, 1.0);
  slider1.setNumberFormat(G4P.DECIMAL, 2);
  slider1.setOpaque(false);
  slider1.addEventHandler(this, "slider1_change1");
}

synchronized public void win_draw1(GWinApplet appc, GWinData data) {
  appc.background(230);
}

// Handle events for slider1
public void slider1_change1(GSlider source, GEvent event) {
  println("slider1 - GSlider event occured " + System.currentTimeMillis()%10000000 );
}

GUI Builder tool makes very easy! Thanks

But i think i didn't express myself very well...When i said "window", actually i meant more like a page... The program has only one window, but there are several diferent pages, or tabs...
The problem is that i call createGUI(); in setup(), so the slider appears in all of the pages...
Sorry about the misunderstanding...

Simply show / hide the slider when required with

slider1.setVisible(true);

slider1.setVisible(false);
