popup menu for use in p5?

hi
is there a way to use java PopupMenus inside
the p5 api? this could be pretty useful for
many applications written in p5. i tried but
it was so unsatisfying.
thanks for any hints

you can use the awt menu items. i tried it months ago. here is my unfinished sketch:
Code:
TextField inputLine = new TextField("inputLine", 15);
TextArea inputArea = new TextArea("inputArea", 5, 20);
void setup() {
size(640, 480);
//setBounds(0,0,100,100);
add(inputLine);
add(inputArea);
}
void loop()
{
background(255);
}
void mousePressed()
{
String iLine = inputLine.getText();
String iArea = inputArea.getText();
println("inputLine: " + iLine);
println("inputArea: " + iArea);
}

thank you michael. just wanted to build
a little menu that pops up downwards if you
click on the little arrow on the right,
also because building gui in p5 is not
really fun.

i think that's you are looking for:
Code:
public PopupMenu popup;
void setup()
{
size(640, 480);
popup = new PopupMenu("Popup Sample");
MenuItem m = new MenuItem("first entry");
m.setActionCommand("first");
MenuItem n = new MenuItem("second entry");
popup.add(m);
popup.add(n);
add(popup);
}
void loop()
{
background(255);
}
void mousePressed()
{
//popup.show(this,mouseX,mouseY);
//or
popup.show(this,100,100);
}

it does not look nice but it is a kind of pulldown menu. in ths code there is a no actionlistener interface implemented. in order to recognize the clicked item you have to implement the actionlstener to your applet:
Code:
public class mySketch() extends BApplet implements ActionListener
{
void setup()
...
void loop()
...
public void actionPerformed(ActionEvent event)
{
if (event.getActionCommand()=="first") {
// the method to do when clicked
println("first item clicked");
}
}
}

i should not write too fast with an us keyboard..
that's the right code. it works fine:
Code:
import java.awt.*;
import java.awt.event.*;
public class mySketch extends BApplet implements ActionListener
{
public PopupMenu popup;
public void setup()
{
size(640, 480);
popup = new PopupMenu("Popup Sample");
MenuItem m = new MenuItem("first entry");
// set the string to compare when an item is clicked
m.setActionCommand("first");
m.addActionListener(this);
popup.add(m);
MenuItem n = new MenuItem("second entry");
n.setActionCommand("second");
n.addActionListener(this);
popup.add(n);
add(popup);
}
public void loop()
{
background(255);
}
public void mousePressed()
{
//popup.show(this,mouseX,mouseY);
//or
popup.show(this,100,100);
}
public void actionPerformed(ActionEvent event)
{
// ask which item has been clicked
if (event.getActionCommand()=="first") {
println("first item clicked");
}
else if (event.getActionCommand()=="second") {
println("second item clicked");
}
}
}
