[ULC-developer] Editable Cells in TableTree

[Keuch, Carsten]

Hi all,

 

i have implemented a Tabletree and want some cells of a column to be editable to flush later into database. For this issue i implement a CellEditor and CellRenderer as listed below. But now i'm running into difficulties. The ULCTextField implements the IEditorComponent indeed but not the IRendererComponent and 'cause of that a ClassCastException is thrown by execution (both components are added to the table). On the other hand, when i try the same with an ULCLabel, the super constructor of DefaultCellEditor is undefined for ULCLable ('cause not implementing the IEditorComponent interface) but implements IRendererComponent instead!?!?! How can i solve this or how can i edit cells in an other way?

My second question is, how i can get then the edited values and flush them into db by clicking on a button for example? Pls see the snippet below.

 

Thanks and kind regards,

private static class CellEditor extends DefaultCellEditor {

 

  public CellEditor(ULCTextField field) {
   super(field);
  }

 

  public IEditorComponent getTableTreeCellEditorComponent(
    ULCTableTree tableTree, Object value, boolean selected,
    boolean expanded, boolean leaf, Object node) {
   ULCTextField field = (ULCTextField) getEditorComponent();
   // field.setText((String) node);
   return field;
  }

 

 }

 

 private static class CellRenderer extends ULCTextField implements
   ITableTreeCellRenderer {
  
  public IRendererComponent getTableTreeCellRendererComponent(
    ULCTableTree tableTree, Object value, boolean selected,
    boolean hasFocus, boolean expanded, boolean leaf, Object node) {
   // setText((String) node);
   return (IRendererComponent) this;
  }
