Open Dialog (Frame?)
« on: May 6th, 2004, 11:00pm » |

Hi I saw how Moovl has an Open and Save dialog, and i wanted to use them with my own stuff. I know it's pretty hard to get that to work with applets, so I only really want it to work inside P5 for now.
I found this code that's supposed to do it
Code:| FileDialog = new FileDialog(Frame parent, String title, int mode); |
|
It asks for a Frame as one of the parameters..
What is a Frame, and if P5 has one, how can I access it?
Oh BTW I found that code here http://jan.netcomp.monash.edu.au/java/swingtut/tut1a.html#dialogs

skimmed through the examples given in your link, and found a simple example ... and made this little sketch:
Code:
Hello a;
void setup(){
a = new Hello();
}
void loop(){
}
class Hello extends Frame {
/*
public static void main(String argv[]) {
new Hello();
}
*/
Hello() {
Label hello = new Label("Hello World");
add(hello, "Center");
setSize(200, 200);
setVisible(true);
}
}

hehe, there's no listener set up for closing the Frame (window) - so you have to kill processing to kill the window!

Oh okay thanks Mikkel
I guess all i needed to do is make a new Frame as the parameter
Code:void setup() {
FileDialog fd = new FileDialog(new Frame(), "Yo");
fd.setVisible(true);
System.out.println("Selected: " + fd.getDirectory() + fd.getFile());
} |

That'll give you the path to load a file. Weird.. I wonder what it needs the Frame for then?
Update: Oh I think this will only work on files inside P5's data folder.. I'm loading the files into a Sonia sample but i think that all of the file loading functions assume that everything is in that folder..

I think you pass it a parent reference so that it knows to not pass on mouse clicks to the parent.
e.g. in Internet Explorer 6, if I click File... Open... then whilst the dialog is open I can't click on the webpage or buttons. That's fairly standard in Windows type software - so doubtless Apple did it first, or Xerox, whatever...

sorta but not really.. you can use:
Code:try { // since we're in java-land now
FileInputStream stream = new FileInputStream(new File(directory, filename));
// and then:
String stuff[] = loadStrings(stream);
// or:
String bytes[] = loadBytes(stream);
} catch (Exception e) {
e.printStackTrace();

right, i believe it's to do with some windowing systems using a parent/child model for all windows, in addition to modal dialogs (where you're locking out key presses). using just "new Frame()" works fine in most circumstances.

hmm, sorry scloppy, being a bit tired, and trying to be clever on these boards isn't always a good thing... hehe, i didn't really read your initial post well enough!
FileDialog ... nice! (and now, i'll shut up!)
