mysql - How to create dynamic columns with values with TableViewer Jface -

i need create dynamic columnas in 1 tableviewer, in eclipse rcp application.

the idea need create cross table.

column 0 | column 1| column 2| column 3| column n ================================================= data 0,0 | data 0,1| data 0,2| data 0,3| data 0,n data 1,0 | data 1,1| data 1,2| data 1,3| data 1,n data 2,0 | data 2,1| data 2,2| data 2,3| data 2,n data 3,0 | data 3,1| data 3,2| data 3,3| data 3,n 

i'm using create dynamic columns.

    //recuperar crossing block del grupo     (int i=0; < cbscombinado.size(); i++) {         tableviewercolumn = new tableviewercolumn(this.tablecombinadoviewer, swt.none);         tblclmnparcela = tableviewercolumn.getcolumn();         tblclmnparcela.setwidth(100);         tblclmnparcela.settext( cbscombinado.get(i).getnroparcela().tostring());         tblclmnparcela.setdata(cbscombinado.get(i)); //asigno el participante.     }; 

so i'm reading records database create columns each record.

the problem need retrieve data set in te column. need id of column n , row i, query database.

any idea? best regards

hi, approach right now. create classwith arraylist of columns:

class grilla {     private bloquecruzamiento bc_x;     private arraylist<bloquecruzamiento> bc_list_y;     private boolean selected;  } 

and contentprovider:

class bloquecruzacombcontentprovider implements istructuredcontentprovider {      public void dispose() {         // todo auto-generated method stub      }      public void inputchanged(viewer viewer, object oldinput, object newinput) {         // todo auto-generated method stub      }      @suppresswarnings("unchecked")     public object[] getelements(object obj) {         arraylist<grilla> grid = (arraylist<grilla>) obj;         return grid.toarray();     }  }    

and how populate arraylist:

    list<grilla> cbsarrayl = new  arraylist<grilla>() ;     grilla grid = new grilla();      (bloquecruzamiento cb : cbs) {         grid.bc_x       = cb;         grid.bc_list_y  = new arraylist<bloquecruzamiento>();         grid.selected   = false;          (bloquecruzamiento ccb : cbscombinado)         {             grid.bc_list_y.add(ccb);         }         cbsarrayl.add(grid);         grid = new grilla();     }      tablecombinadoviewer.setcontentprovider(new bloquecruzacombcontentprovider());     tablecombinadoviewer.setlabelprovider(new bloquecruzacomblabelprovider());     if (cbs!=null)  tablecombinadoviewer.setinput(cbsarrayl); 

my goal make each cell editable, under circumstances should not editable. regards again

i assume have 1 java class each of table structures displaying. can hence use java reflection api give headings table viewer columns , display data

edit: see ur code has 70% of needs done. repeating steps additional details sake of understanding

1. define java class describing fields in table. include getters , setters fields. if there 'n' different tables create 'n' such classes getters , setters. 1 of classes named employee
2. an array list of 1 of above classes become input tableviewer use .use tableviewer.setinput(emplist)
3. now implement own label provider. within labelprovider's getvalue() method should make use of reflection api call getxxxx() of table field wish show. reference here. reflection nothing introspection api provided java gets details class , it's properties.
4. you can enable editing creating new class sub-classing editingsupport class , adding instance columnviewer's addeditingsupport() method

remember tableviewer column headers can field names of employee class can got reflection api .

hope clarifies
