RE: Is it possible to get hold of the underlying Swing table from ULCTable?

Hi,

 

I am sorry for not explaining my issue properly.

 

I want to know if I can call the restoreState method. If I am allowed to call the restoreState method then what should be the input parameter for this method?

 

Regards

Prasanta

Hi,

 

The function

 

public UiJTable getBasicTable() {

}

 

on clientside (inside UIExtendedTable) should give you access to the underlying swing table (UiJTable is a child of JTable).

 

 

And you surely want to move the UIExtendedTable to an own class that will be deployed/downloaded on the client side :-)

 

Best regards,

Hi All,

Is it possible to get hold of the underlying swing table from the ULCTable?

In order to achieve wrapping in the column header I have done the following:

• Created both extended ULCTable and UITable class.
• The ULC class just overrides typeString() and the UI class restoreState(). The text area renderer component is eventually set on the underlying Swing table in the restoreState() method after calling super().

Code Snippet is as given below:

 

 protected String typeString() {
  // works only in development mode; to be replaced by a full-qualified package string
  return UIExtendedTable.class.getName();
 }
 
 public static class UIExtendedTable extends UITable {
  public void restoreState(Anything args) {
   super.restoreState(args);

 

   JWordWrapTableHeader headerRenderer = new JWordWrapTableHeader();

 

   for (Enumeration enumeration = getBasicTable().getColumnModel()
     .getColumns(); enumeration.hasMoreElements();) {
    TableColumn column = (TableColumn) enumeration.nextElement();
    column.setHeaderRenderer(headerRenderer);
   }
  }
  
  private static class JWordWrapTableHeader extends JTextArea implements TableCellRenderer {
   public JWordWrapTableHeader() {
    setLineWrap(true);
    setWrapStyleWord(true);
    setBackground(new Color(223, 235, 252));
    setBorder(UIManager.getBorder("TableHeader.cellBorder"));
   }
  
   public Component getTableCellRendererComponent(JTable table,
     Object value, boolean isSelected, boolean hasFocus, int row,
     int column) {
    setText((String) value);
    setSize(table.getColumnModel().getColumn(column).getWidth(),
      getPreferredSize().height);
    return this;
   }
  }
 }

But my project has an additional requirement. My project has something called a field chooser utility. When a user clicks on the field chooser he gets a list of columns. The user can select any number of columns that he would like to view and the table is refreshed with the selected columns. While refreshing the table I am using fireTableStructureChanged() method. When I call fireTableStructureChanged() method it is removing the effect of word wrapping in the column header. I need to set the renderer again on the underlying Swing table.

Is it possible to get hold of the underlying Swing table from ULCTable? If this is possible I can again set the renderer on the underlying Swing table after calling fireTableStructureChanged() method? If this is not possible is there a way to set the renderer again after calling fireTableStructureChanged() method?

Thanks & Regards
