Hi Andreas,
Thank you so much for cp5 - I just started using it and it's incredible(!)

I've been trying to make something that requires multiple buttons to be selected at once (kind of like selecting multiple files in a folder using Command + Click) but I couldn't tell if there's a controller/group class that does this. I've taken a look at MultiList, MultiListButton, DropdownList, but all of these look like they only allow a single selection. (I've looked through the javadocs too but couldn't find anything).

Is there a class that will let me multi-select items? If not, do you have a suggestion for how I should approach this? My thought was that I could extend one of the classes so that a click would toggle select/deselect, or maybe just make an arrayList of Tabs/Buttons but I figure you've probably already got a solution for this in there somewhere that I'm missing. :)

Thanks,

adila

P2D/OPENGL text rendering in 2.0b8

Hi,
I'd like to use a bunch of PShapes in my sketch but have found that when I change my renderer to either P2D or OPENGL, my text starts looking awful. If I use the default JAVA2D renderer though, then the text looks great but my PShapes don't appear.

I read this post on text rendering in P2D/P3D but my problem isn't that the text doesn't appear so much as the text just looks bad.(I get the same thing using both createFont(name,size,true) and loadFont(".... .vlw")).

Here's some simple code I wrote up to test things out. It's loosely based on the star example at http://processing.org/learning/pshape/ (with some changes to make it work -- denoted by arrows in the comments).
2. PShape aShape;
3. PFont font;
4. void setup() {
5. size(500,500,OPENGL); //<-- changed from size(500,500)
6. smooth();
7. font = createFont("serif",20,true);
8. // First create the shape
9. aShape = createShape();
10. //aShape = new PShape(3); //<-- need this if you're using default renderer or it'll throw an error
11. aShape.beginShape(); //<-- added this in
12. // You can set fill and stroke
13. aShape.fill(102); //<-- moved from before 'aShape = createShape()'
14. aShape.stroke(255); //<-- moved from before 'aShape = createShape()'
15. aShape.strokeWeight(2); //<-- moved from before 'aShape = createShape()'
17. // Here, we are hardcoding a series of vertices
18. aShape.vertex(0, 0);
19. aShape.vertex(100,0);
20. aShape.vertex(100,100);
21. aShape.vertex(0,100);
23. // We are done with the shape
24. aShape.endShape(CLOSE); //<-- changed from aShape.end();
25. }
27. void draw() {
28. background(255);
29. // draw the shape.
30. shape(aShape,mouseX,mouseY); // <-- doesn't appear if I use default renderer
32. // write some text
33. fill(0); textAlign(CENTER,CENTER);
34. int i=-1; while(++i<10){
35. textSize(15+i);
36. text("bigger",width/2,23*i+20);
37. }
38. }
Any idea what I'm doing wrong?

Thanks!

SelectFolder() and selectInput() in Processing 2.0 vs 1.6

Hi,

In 1.6,
1. String selectedFolder = selectFolder(String);
2. String selectedInput = selectInput(String);
would prompt the user to select the folder / file with the output being the folder path or file path respectively.

(e.g. Users/adilapapaya/Desktop/myFolder);

In 2.0, selectFolder(String) and selectInput(String) no longer exists. Instead, the closest is requires a callback function which you have to add to your sketch telling it what to do with the selected folder or file. The javadoc/reference gives a nice example of this but I was wondering if it would be possible to keep the previous version of 'selectFolder(String)' and selectInput(String) in there too in v2.0.x.

Not sure if this is helpful, but here's the source code for the previous versions of selectFolder and selectInput. (Both refer to a bunch of other functions though and I haven't checked if those still exist in 2.0).

selectFolder:
1. /*
2. * Opens a platform-specific file chooser dialog to select a folder for
3. * input. This function returns the full path to the selected folder as a
4. * <b>String</b>, or <b>null</b> if no selection.
5. */
6. public String selectFolder(final String prompt) {
7. checkParentFrame();
9. try {
10. SwingUtilities.invokeAndWait(new Runnable() {
11. public void run() {
12. if (platform == MACOSX) {
13. FileDialog fileDialog =
14. new FileDialog(parentFrame, prompt, FileDialog.LOAD);
15. System.setProperty("apple.awt.fileDialogForDirectories", "true");
16. fileDialog.setVisible(true);
17. System.setProperty("apple.awt.fileDialogForDirectories", "false");
18. String filename = fileDialog.getFile();
19. selectedFile = (filename == null) ? null :
20. new File(fileDialog.getDirectory(), fileDialog.getFile());
21. } else {
22. JFileChooser fileChooser = new JFileChooser();
23. fileChooser.setDialogTitle(prompt);
24. fileChooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
26. int returned = fileChooser.showOpenDialog(parentFrame);
27. System.out.println(returned);
28. if (returned == JFileChooser.CANCEL_OPTION) {
29. selectedFile = null;
30. } else {
31. selectedFile = fileChooser.getSelectedFile();
32. }
33. }
34. }
35. });
36. return (selectedFile == null) ? null : selectedFile.getAbsolutePath();
38. } catch (Exception e) {
39. e.printStackTrace();
40. return null;
41. }
42. }
```
                  
                   
                    

                   
                   
                    selectInput:
                     
                   
                    
                    
                    
                     
                     /** Open a platform-specific file chooser dialog to select a file for input.
                        * @return full path to the selected file, or null if no selection.*/  
                     public String selectInput(String prompt) {
                           return selectFileImpl(prompt, FileDialog.LOAD);
                     }
                    
                   
                   
                    Many thanks,

Statistics library for Processing

Hi,

I noticed that Processing doesn't have a basic statistics library, so I went ahead and created one.

It's called "papaya" and can be downloaded by clicking on this link and scrolling down to the "downloads" section, or, if you want to download the .zip file directly, just click here. Further details are provided in the javadoc as well as on the project website ( http://www.holypapayaresearch.com/papayastatistics.html). Source code is included in the downloadable folder too.

Feel free to check it out and let me know what you think,
