I have some trouble with dialog boxes using javax.swing.JOptionPane.
My simple program is on the bottom. If I put showMessageDialog in draw(), it works fine. Draw waits for user to press ok before continuing. If I put showMessageDialog in any of the mouse functions, like click, press, release, it freezes screen. I want to pop up a dialog when I click the mouse but why doesn't this work? But strangely if I drag the dialog away from processing window, then click ok I get no problem. I did some tests. The program freezes if my mouse click on the ok button is within processing window! This seems to be an mouse click handling problem within processing. How do I solve this problem? Thank you!!!

void setup()
{
 size(400,300);
}

void draw()
{
 background(150);
 line(0,0,width-1,height-1);
}

void mouseReleased()
{
 println("mouse released");
}

void mouseClicked()
{
 println("mouse clicked");
 javax.swing.JOptionPane.showMessageDialog(frame,"what?");
}
void mousePressed()
{
 println("mouse pressed");
}

Thanks PhiLho.

So this means if I want to input a number, I need to keep reading keyboard or try someone's text input library?

Getting a number from user is kind of a basic necessity for me. What do you suggest I do? I've already created my buttons class with several features. I know how to make something from scratch now but I'm not willing to make a text input from scratch. Seems time consuming. Can I somehow exit graphic mode when using dialog and re-enter it?

Thanks for the info Cedric. It seems the controlP5 controls pick up mouse clicks and don't discard them. I can still pick up the same click in my mouseClicked(). Is there an option to stop throwing mouse and keyboard events to mouseClicked() and such? I'll try to find an appropriate board to ask any future questions on controlP5.

Update 2: this method seems to work fine. One observation, when draw stops, mouse events are still processed by the processing mouse functions like mouseClicked().

Update: the method worked. I was wrong earlier. I included noLoop() and loop() at the wrong place. What a silly mistake. I'll incorporate it into my main program and test it out. Update when I finish testing.

NoahBuddy,

I tried this way you suggested. It still won't work. Same screen freeze. Is there any way to minimize processing window so the clicks don't land inside processing and then restore processing window? Thanks.
