Hello,

I am working with processing version 2.0b3 version and trying to use treeMappa library to create treemaps for my project. For installation purpose, I am following the instructions mentioned at the this link. I have also installed gicenter Utilities and have access to them for sure since I can run their examples.

When I run a small example on the website for treeMappa, I keep getting the following error:-
No library found for org.gicentre.treemappa
Libraries must be installed in a folder named 'libraries' inside the 'sketchbook' folder.

I am not installing a library for the first time...I have done it a number of times before (successfully). But this is just giving me a hard time.

Here is the directory structure where the library files are.

Does anyone have a clue as to what could be the problem? Does treeMappa work for the 2.0b3 version of processing or I am doing something really silly?

Hi,

I am using processing 2.0 to create an application to display graphs and tabular data. I have created an applet and did a show(false) to keep it hidden.

1. class BApplet extends PApplet
   {
       int aScaleFactor;
       Integer tabPositionx, tabPositiony, tabWidth, tabHeight;
       Integer tabColor;
       ControlP5 cp5Applet;
       static public void main(String args[])
       {
       PApplet.main(new String[] { "BApplet" });
       }
       public void setup()
       {
           //size(400, 300);
           cp5Applet = new ControlP5(this);
           cp5Applet.setBroadcast(true);
           data = "";
           label = "";      
           addTextArea(#7A5200, 50 * scaleFactor, 50 * scaleFactor, 800 * scaleFactor, 800 * scaleFactor); 
           //noLoop();
       }
       public void mousePressed()
       {
         if (mouseX > 10 * aScaleFactor && mouseX < 30 * aScaleFactor)
         {
           if (mouseY > 10 * aScaleFactor && mouseY < 30 * aScaleFactor)
              show(false);
         }
       }
      
       void renderCloseButton()
       {     
         fill(#7A0029);
         rect(10, 10, 20, 20);
         noFill();
         strokeWeight(1);
         stroke(0,0,0);
         line(10,10,30,30);
         line(10,30,30,10);
        
       }
      
       void addTextArea(Integer colr, Integer px, Integer py, Integer swid, Integer sht)
       {
         tabPositionx = px;
         tabPositiony = py;
         tabWidth = swid;
         tabHeight = sht;
         tabColor = colr;
        
       textTable = cp5Applet.addTextarea("DataTable");
         textTable.setPosition( tabPositionx * aScaleFactor, tabPositiony * aScaleFactor);
         textTable.setSize( tabWidth * aScaleFactor, tabHeight * aScaleFactor);
         textTable.setFont(createFont("arial", 15));
         textTable.setLineHeight(17);
         textTable.setColor(color(128));
         textTable.setColorBackground(color(255,100));
         textTable.setColorForeground(color(255,100));
         //textTable.setScrollActive(color(255));
         //textTable.showScrollbar();
       }
      
       
    }
   

Here is what is in the setup() of the main file

1. BApplet appl_table;
   appl_table = new BApplet();
   add(appl_table);
   appl_table.init();
   appl_table.show(false);
   

The applet shows on a button(controlp5 Button) click inside controlEvent() of the main file.

1. if (controlName == "Table")
       {
         //println("Plot button was pressed" );
         String data = computeDataForTableWindow();
         String label = subGraphs[currentTab].graphTitle;
         appl_table.setDataToShow ( data, label );
         appl_table.show(true);
         return;
       }
   

After I close the applet using the X icon ( renderCloseButton()), I am not able to type anything in the ControlP5 textfields on the main sketch.

Any ideas?

Best,
Bisht

Hello,

I need to create a table in processing, of fixed rows and variable column. The data is available in array objects. This table will open from a button click in a different window.

What is the best way of doing it? I was thinking of rendering rectangles for each row in alternating colors and then adding field value using coordinates for each cell. This certainly seems a lot of processing. Can anyone suggest an easier option?

Hoping to hear.


Cheers!
