Class Searchable

java.lang.Object
com.jidesoft.swing.Searchable
Direct Known Subclasses:
ComboBoxSearchable, ListSearchable, TableSearchable, TextComponentSearchable, TreeSearchable

public abstract class Searchable extends Object
JList, JTable and JTree are three data-rich components. They can be used to display a huge amount of data so searching function will be very a useful feature in those components. Searchable is such a class that can make JList, JTable and JTree searchable. User can simply type in any string they want to search for and use arrow keys to navigate to next or previous occurrence.

Searchable is a base abstract class. ListSearchable, TableSearchable and TreeSearchable are implementations to make JList, JTable and JTree searchable respectively. For each implementation, there are five methods need to be implemented.

  • protected abstract int getSelectedIndex()
  • protected abstract void setSelectedIndex(int index, boolean incremental)
  • protected abstract int getElementCount()
  • protected abstract Object getElementAt(int index)
  • protected abstract String convertElementToString(Object element)

Please look at the javadoc of each method to learn more details.

The keys used by this class are fully customizable. Subclass can override the methods such as isActivateKey(java.awt.event.KeyEvent), isDeactivateKey(java.awt.event.KeyEvent), isFindFirstKey(java.awt.event.KeyEvent),isFindLastKey(java.awt.event.KeyEvent), isFindNextKey(java.awt.event.KeyEvent), isFindPreviousKey(java.awt.event.KeyEvent) to provide its own set of keys.

In addition to press up/down arrow to find next occurrence or previous occurrence of particular string, there are several other features that are very handy.

Multiple selection feature - If you press CTRL key and hold it while pressing up and down arrow, it will find next/previous occurrence while keeping existing selections.
Select all feature - If you type in a searching text and press CTRL+A, all the occurrences of that searching string will be selected. This is a very handy feature. For example you want to delete all rows in a table whose name column begins with "old". So you can type in "old" and press CTRL+A, now all rows beginning with "old" will be selected. Pressing delete will delete all of them.
Basic regular expression support - It allows '?' to match any letter or digit, or '*' to match several letters or digits. Even though it's possible to implement full regular expression support, we don't want to do that. The reason is the regular expression is very complex, it's probably not a good idea to let user type in such a complex expression in a small popup window. However if your user is very familiar with regular expression, you can add the feature to Searchable. All you need to do is to override compare(String, String) method and implement by yourself.

As this is an abstract class, please refer to to javadoc of ListSearchable,TreeSearchable, and TableSearchable to find out how to use it with JList, JTree and JTable respectively.

This component has a timer. If user types very fast, it will accumulate them together and generate only one searching action. The timer can be controlled by setSearchingDelay(int).

By default we will use lightweight popup for the sake of performance. But if you use heavyweight component which could obscure the lightweight popup, you can call setHeavyweightComponentEnabled(boolean) to true so that heavyweight popup will be used.

When a Searchable is installed on a component, component.getClientProperty(Searchable.CLIENT_PROPERTY_SEARCHABLE) will give you the Searchable instance. You can use static method getSearchable(javax.swing.JComponent) to get it too.

Last but not the least, only one Searchable is allowed on a component. If you install another one, it will remove the first one and then install the new one.

  • Method Details

    • getSelectedIndex

      protected abstract int getSelectedIndex()
      Gets the selected index in the component. The concrete implementation should call methods on the component to retrieve the current selected index. If the component supports multiple selection, it's OK just return the index of the first selection.

      Here are some examples. In the case of JList, the index is the row index. In the case of JTree, the index is the row index too. In the case of JTable, depending on the selection mode, the index could be row index (in row selection mode), could be column index (in column selection mode) or could the cell index (in cell selection mode).

      Returns:
      the selected index.
    • setSelectedIndex

      protected abstract void setSelectedIndex(int index, boolean incremental)
      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.
      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.
    • adjustSelectedIndex

      public void adjustSelectedIndex(int index, boolean incremental)
      Sets the selected index. The reason we have this method is just for back compatibility. All the method do is just to invoke setSelectedIndex(int, boolean).

      Please do NOT try to override this method. Always override setSelectedIndex(int, boolean) instead.

      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.
    • getElementCount

      protected abstract int getElementCount()
      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.
      Returns:
      the total element count.
    • getElementAt

      protected abstract Object getElementAt(int index)
      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.
      Parameters:
      index - the index
      Returns:
      the element at the specified index.
    • convertElementToString

      protected abstract String convertElementToString(Object element)
      Converts the element that returns from getElementAt() to string.
      Parameters:
      element - the element to be converted
      Returns:
      the string representing the element in the component.
    • convertToString

      public String convertToString(Object element)
      Converts the element to String.

      This method will invoke convertElementToString(Object) only. This method is added to provide a public method for ShrinkSearchSupport without breaking the existing code of the customers.

      Parameters:
      element - the element to be converted
      Returns:
      the string representing the element in the component.
      Since:
      3.4.5
    • isHideSearchPopupOnEvent

      public boolean isHideSearchPopupOnEvent()
      Get the flag indicating if the search popup should be hidden on the component's event.

      By default, the value is true so that the search popup will be hidden anyway when the component get related events. However, you could set this flag to false if you don't want to hide the search popup in some scenarios. For example, JIDE ComboBoxShrinkSearchableSupport will set this flag to false temporarily when it tries to shrink the list.

      Returns:
      true if the search popup is hidden on event. Otherwise false.
    • setHideSearchPopupOnEvent

      public void setHideSearchPopupOnEvent(boolean hideSearchPopupOnEvent)

      Returns:
      a FocusListener.
    • uninstallListeners

      public void uninstallListeners()

      Parameters:
      cursor - the new position of the cursor.
      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.
    • highlightAll

      protected void highlightAll()
      Highlight all matching cases in the target.

      In default implementation, it will just search all texts in the target to highlight all. If you have a really huge text to search, you may want to override this method to have a lazy behavior on visible areas only.

    • cancelHighlightAll

      protected void cancelHighlightAll()
      Cancel highlight all.

      By default, it does nothing. However, if you want to override highlightAll(), you may want to override this method to notify your Searchable that the highlightAll button is to be released.
