Class JXTaskPane

  • All Implemented Interfaces:
    ImageObserver, MenuContainer, Serializable, Accessible, JXCollapsiblePane.CollapsiblePaneContainer

    public class JXTaskPane
    extends JPanel
    implements JXCollapsiblePane.CollapsiblePaneContainer
    JXTaskPane is a container for tasks and other arbitrary components.

    Several JXTaskPanes are usually grouped together within a JXTaskPaneContainer. However it is not mandatory to use a JXTaskPaneContainer as the parent for JXTaskPane. The JXTaskPane can be added to any other container. See JXTaskPaneContainer to understand the benefits of using it as the parent container.

    JXTaskPane provides control to expand and collapse the content area in order to show or hide the task list. It can have an icon, a title and can be marked as special. Marking a JXTaskPane as special (setSpecial(boolean) is only a hint for the pluggable UI which will usually paint it differently (by example by using another color for the border of the pane).

    When the JXTaskPane is expanded or collapsed, it will be animated with a fade effect. The animated can be disabled on a per component basis through setAnimated(boolean). To disable the animation for all newly created JXTaskPane, use the UIManager property: UIManager.put("TaskPane.animate", Boolean.FALSE);.

    Example:

     
     JXFrame frame = new JXFrame();
     
     // a container to put all JXTaskPane together
     JXTaskPaneContainer taskPaneContainer = new JXTaskPaneContainer();
     
     // create a first taskPane with common actions
     JXTaskPane actionPane = new JXTaskPane();
     actionPane.setTitle("Files and Folders");
     actionPane.setSpecial(true);
     
     // actions can be added, a hyperlink will be created
     Action renameSelectedFile = createRenameFileAction();
     actionPane.add(renameSelectedFile);
     actionPane.add(createDeleteFileAction());
     
     // add this taskPane to the taskPaneContainer
     taskPaneContainer.add(actionPane);
     
     // create another taskPane, it will show details of the selected file
     JXTaskPane details = new JXTaskPane();
     details.setTitle("Details");
      
     // add standard components to the details taskPane
     JLabel searchLabel = new JLabel("Search:");
     JTextField searchField = new JTextField("");
     details.add(searchLabel);
     details.add(searchField);
     
     taskPaneContainer.add(details);
     
     // put the action list on the left 
     frame.add(taskPaneContainer, BorderLayout.EAST);
     
     // and a file browser in the middle
     frame.add(fileBrowser, BorderLayout.CENTER);
     
     frame.pack();
     frame.setVisible(true);

        Sets the icon to be displayed in the border of this pane. Some pluggable UIs may impose size constraints for the icon. A size of 16x16 pixels is the recommended icon size.
        Parameters:

      • isSpecial

        public boolean isSpecial()

        public void setSpecial​(boolean special)
        Sets this pane to be "special" or not. Marking a JXTaskPane as special is only a hint for the pluggable UI which will usually paint it differently (by example by using another color for the border of the pane).

        Usually the first JXTaskPane in a JXTaskPaneContainer is marked as special because it contains the default set of actions which can be executed given the current context.

        Parameters:
        special - true if this pane is "special", false otherwise
      • setScrollOnExpand

        Parameters:
        scrollOnExpand - true to scroll this group to be visible if this group is expanded.
        See Also:
        setCollapsed(boolean)
      • isScrollOnExpand

        public boolean isScrollOnExpand()
        Should this group scroll to be visible after this group was expanded.
        Returns:
        true if we should scroll false if nothing should be done.
      • setCollapsed

        public void setCollapsed​(boolean collapsed)
        Expands or collapses this group.
        Parameters:

        public boolean isCollapsed()
        Returns the collapsed state of this task pane.
        Returns:
        true if the task pane is collapsed; false otherwise
      • setAnimated

        public void setAnimated​(boolean animated)
        Enables or disables animation during expand/collapse transition.
        Parameters:
        animated -
      • isAnimated

        public boolean isAnimated()
        Returns true if this task pane is animated during expand/collapse transition.

      • getMnemonic

        public int getMnemonic()
        Returns the keyboard mnemonic for the task pane.
        Returns:
        the keyboard mnemonic for the task pane
      • setMnemonic

        public void setMnemonic​(int mnemonic)
        Sets the keyboard mnemonic on the task pane. The mnemonic is the key which when combined with the look and feel's mouseless modifier (usually Alt) will toggle this task pane.

        A mnemonic must correspond to a single key on the keyboard and should be specified using one of the VK_XXX keycodes defined in java.awt.event.KeyEvent. Mnemonics are case-insensitive, therefore a key event with the corresponding keycode would cause the button to be activated whether or not the Shift modifier was pressed.

        If the character defined by the mnemonic is found within the task pane's text string, the first occurrence of it will be underlined to indicate the mnemonic to the user.

        Parameters:
        mnemonic - the key code which represents the mnemonic
        See Also:
        KeyEvent, setDisplayedMnemonicIndex(int)
      • getDisplayedMnemonicIndex

        public int getDisplayedMnemonicIndex()
        Returns the character, as an index, that the look and feel should provide decoration for as representing the mnemonic character.
        Returns:
        index representing mnemonic character
        Since:
        1.4
        See Also:
        setDisplayedMnemonicIndex(int)
      • setDisplayedMnemonicIndex

        public void setDisplayedMnemonicIndex​(int index)
                                       throws IllegalArgumentException
        Provides a hint to the look and feel as to which character in the text should be decorated to represent the mnemonic. Not all look and feels may support this. A value of -1 indicates either there is no mnemonic, the mnemonic character is not contained in the string, or the developer does not wish the mnemonic to be displayed.

        The value of this is updated as the properties relating to the mnemonic change (such as the mnemonic itself, the text...). You should only ever have to call this if you do not wish the default character to be underlined. For example, if the text was 'Save As', with a mnemonic of 'a', and you wanted the 'A' to be decorated, as 'Save As', you would have to invoke setDisplayedMnemonicIndex(5) after invoking setMnemonic(KeyEvent.VK_A).

        Parameters:
        index - Index into the String to underline
        Throws:
        IllegalArgumentException - will be thrown if index is >= length of the text, or < -1
        Since:
        1.4
