Class TableSearchable

  • All Implemented Interfaces:
    java.beans.PropertyChangeListener, java.util.EventListener, javax.swing.event.TableModelListener
    public class TableSearchable
extends Searchable
implements javax.swing.event.TableModelListener, java.beans.PropertyChangeListener
    TableSearchable is an concrete implementation of Searchable that enables the search function in JTable.

    It's very simple to use it. Assuming you have a JTable, all you need to do is to call 

     JTable table = ....;
 TableSearchable searchable = new TableSearchable(table);
    Now the JTable will have the search function.

    As JTable is a two dimension data, the search is a little different from JList and JTree which both have one dimension data. So there is a little work you need to do in order to convert from two dimension data to one dimension data. We use the selection mode to determine how to convert. There is a special property called mainIndex. You can set it using setMainIndex(). If the JTable is in row selection mode, mainIndex will be the column that you want search at. Please note you can change mainIndex at any time.

    On the other hand, if the JTable is in column selection mode, mainIndex will be the row that you want search at. There is one more case when cell selection is enabled. In this case, mainIndex will be ignore; all cells will be searched.

    In three cases above, the keys for find next and find previous are different too. In row selection mode, up/down arrow are the keys. In column selection mode, left/right arrow are keys. In cell selection mode, both up and left arrow are keys to find previous occurrence, both down and right arrow are keys to find next occurrence.

    In addition, you might need to override convertElementToString() to provide you own algorithm to do the conversion. 

     JTable table = ....;
 TableSearchable searchable = new TableSearchable(table) {
      protected String convertElementToString(Object object) {
          ...
      }
 };

    Additional customization can be done on the base Searchable class such as background and foreground color, keystrokes, case sensitivity,

    • Method Detail

      • installListeners

        public void installListeners()
        Description copied from class: Searchable
        Installs necessary listeners to the component. This method will be called automatically when Searchable is created.
        Overrides:
        installListeners in class Searchable

      • uninstallListeners

        public void uninstallListeners()
        Description copied from class: Searchable
        Uninstall the listeners that installed before. This method is never called because we don't have the control of the life cycle of the component. However you can call this method if you don't want the component to be searchable any more.
        Overrides:
        uninstallListeners in class Searchable

      • setSelectedIndex

        protected void setSelectedIndex​(int index,
                                boolean incremental)
        Description copied from class: Searchable
        Sets the selected index. The concrete implementation should call methods on the component to select the element at the specified index. The incremental flag is used to do multiple select. If the flag is true, the element at the index should be added to current selection. If false, you should clear previous selection and then select the element.
        Specified by:
        setSelectedIndex in class Searchable
        Parameters:
        index - the index to be selected
        incremental - a flag to enable multiple selection. If the flag is true, the element at the index should be added to current selection. If false, you should clear previous selection and then select the element.

      • addTableSelection

        protected void addTableSelection​(javax.swing.JTable table,
                                 int rowIndex,
                                 int columnIndex,
                                 boolean incremental)
        Selects the cell at the specified row and column index. If incremental is true, the previous selection will not be cleared. This method will use JTable.changeSelection(int,int,boolean,boolean) method to select the cell if the row and column index is in the range and the cell was not selected. The last two parameters of changeSelection is true and false respectively.
        Parameters:
        table - the table
        rowIndex - the row index of the cell.
        columnIndex - the column index of the cell
        incremental - false to clear all previous selection. True to keep the previous selection.

        Returns:
        true if the table is the row selection.

      • isSearchSelectedRows

        protected boolean isSearchSelectedRows()
        Are we trying to search on multi-columns (but NOT all columns)?
        Returns:

        protected java.lang.Object getElementAt​(int index)
        Description copied from class: Searchable
        Gets the element at the specified index. The element could be any data structure that internally used in the component. The convertElementToString method will give you a chance to convert the element to string which is used to compare with the string that user types in.
        Specified by:
        getElementAt in class Searchable
        Parameters:
        index - the index

                                      int rowIndex,
                                      int columnIndex)
        Get string value of the table.
        Parameters:
        table - the JTable
        rowIndex - the row index
        columnIndex - the column index
        Returns:
        the string value of the cell in the table.

      • getElementCount

        protected int getElementCount()
        Description copied from class: Searchable
        Gets the total element count in the component. Different concrete implementation could have different interpretation of the count. This is totally OK as long as it's consistent in all the methods. For example, the index parameter in other methods should be always a valid value within the total count.
        Specified by:
        getElementCount in class Searchable
        Returns:
        the total element count.
