How to run the activiti source code?

[balaji1]

Hi,

1. We have checked out the source code from SVN and installed in SVN.
Can you please tell us how to build this source code?

ALso what will be the outcome of this process?

2. We have proposed to use activiti plugin for our porject. We need to customise the palette shapes and XML tags. Can you please tell us the process to perform.


Please help us to resolve to above issues. We are badly stuck up here.

you should keep a running reference to the last "group" or "row" (or whatever metaphor works for you ) you created in the loop. Update it to the current one at the end of each iteration in the loop. You can see similar code in the class that creates the DATA_GRID type. Have a look there.

Alternatively, you could also use a GridLayout with the correct number of columns. Then you can simply drop in controls and they will be auto-layouted. How to do that is in the article as well.

Tiese,

I did as per your advice. I would want my property view as Checkbox and Comobolist.Where checkbox names will differ and my combo list remains same.

Below is my code. Still I am facing issue in it.
Composite render(final Composite parent, final TabbedPropertySheetWidgetFactory factory, final FocusListener listener) {

     final Composite result1 = factory.createFlatFormComposite(parent);
     Composite previousParent = result1;
 
     for(int i=1;i<10;i++)
   {
   
      Composite result = factory.createFlatFormComposite(result1);

      FormData data;
   
           
    checkBox = factory.createButton(result,"Test", SWT.CHECK);
    checkBox.setEnabled(true);
    checkBox.setText("Open");
   
    checkBox = factory.createButton(result,"Test", SWT.CHECK);
    checkBox.setEnabled(true);
    checkBox.setText("UnAssigned");
   
          
    comboControl = factory.createCCombo(result,SWT.BORDER_SOLID);
    comboControl.setEnabled(true);
   ….
…

comboControl.addFocusListener(listener);
    comboControl.setItems(ITEMS);
   
     
   
    data = new FormData();
  //  data.left = new FormAttachment(checkBox,40);
    data.top = new FormAttachment(previousParent,10);
    //data.right = new FormAttachment(100); */
    comboControl.setLayoutData(data);
   previousParent = result;
  
   }
    return result1;
  
  }

THanks

What's the problem?

[balaji1]

Tiese,
still  the controls got merged.
I have attached the code. AM I did it in the right way as you said?


Thanks

[tiesebarrell]

So, the code works fine, but your controls are all on top of each other? In that case, it's mainly a case of layouting the controls. For instance, to place them below each other, you should do something like this:

//running reference
Control runningControl = result;

//create first control somehow
FormData data = new FormData();
data.left = new FormAttachment(result, 0)
data.top  = new FormAttachment(runningControl, 0)
control1.setLayoutData(data);

runningControl = control1;

//for each next component
data = new FormData();
data.left = new FormAttachment(result, 0)
data.top  = new FormAttachment(runningControl, 0)
controlX.setLayoutData(data);

runningControl = controlX;

So you basically keep attaching the left side of the components to the parent control, and the top of them to the previous one you created (which makes it end up stuck to the previous one's bottom). You should make sure you create a NEW FormData for each one before you invoke setLayoutData().

This is certainly the longest topic I've ever seen. Many compliments to Tiese. And I hope Balaji will write several blogs about this, that can be used by others to help getting the designer better and better.

[tiesebarrell]

Ronald, thanks for that. In the meantime, it's also helped me understand where the documentation may be lacking or code changes might help others develop extensions to Designer

[ronald_van_kuij]

Ahhh.. so in fact Balaji was your guinea pig 🙂

[balaji1]

Ronald,
Thanks for your compliments

Thanks

Tiese,
I am getting NPE @   comboControl.setLayoutData(data);
Here its the code change done. Please help.

//

public Composite render(final Composite parent, final TabbedPropertySheetWidgetFactory factory, final FocusListener listener) {

    final Composite result1 = factory.createFlatFormComposite(parent);
     Composite previousParent = result1;

     for(int i=1;i<10;i++)
   {

     Composite result = factory.createFlatFormComposite(result1);
    Control runningControl = result;
      FormData data;

      data = new FormData();
      data.left = new FormAttachment(result, 40);
      data.top = new FormAttachment(runningControl, 30);
      comboControl.setLayoutData(data);

      runningControl = comboControl;


    checkBox = factory.createButton(result,"Test", SWT.CHECK);
    checkBox.setEnabled(true);
    checkBox.setText("Open");
    comboControl = factory.createCCombo(result,SWT.BORDER_SOLID);
    comboControl.setEnabled(true);

    if (getPropertyAnnotation().required()) {
      addFieldValidator(comboControl, RequiredFieldValidator.class);
      addFieldValidator(checkBox, RequiredFieldValidator.class);
    }

    if (getPropertyAnnotation().fieldValidator() != null) {
      addFieldValidator(comboControl, getPropertyAnnotation().fieldValidator());
      addFieldValidator(checkBox, getPropertyAnnotation().fieldValidator());
    }

    comboControl.addFocusListener(listener);
    comboControl.setItems(ITEMS);

    data = new FormData();
    data.left = new FormAttachment(result, 40);
    data.top = new FormAttachment(runningControl, 10);
    checkBox.setLayoutData(data);
   
    runningControl = checkBox;
    previousParent = result;
  
  }
    return result1;
  
  }

Thanks
