Class ComponentProvider

java.lang.Object
docking.ComponentProvider
All Implemented Interfaces:
ActionContextProvider, HelpDescriptor
Direct Known Subclasses:
ComponentProviderAdapter, VisualGraphComponentProvider
public abstract class ComponentProvider extends Object implements HelpDescriptor, ActionContextProvider
Abstract base class for creating dockable GUI components within a tool.

The one method that must be implemented is getComponent() which is where the top level Swing JComponent is returned to be docked into the tool. Typically, the GUI components are created in the constructor along with any local actions for the provider. The getComponent() method then simply returns the top level component previously created by this provider.

There are many other methods for configuring how to dock the component, set title information, configure grouping, set the help, add actions, and receive show/hide notifications, some of which are highlighted below. Typically, implementers will use these methods to configure how the GUI component behaves within the tool, and then add the business logic that uses and reacts to the GUI components created in this provider.

To effectively use this class you merely need to create your component, add your actions to this class (addLocalAction(DockingActionIf)) and then add this provider to the tool (addToTool()).

This also provides several useful convenience methods:

There are a handful of stub methods that can be overridden as desired:

Show Provider Action - Each provider has an action to show the provider. For typical, non-transient providers (see setTransient()) the action will appear in the tool's Window menu. You can have your provider also appear in the tool's toolbar by calling addToTool().

Historical Note: This class was created so that implementors could add local actions within the constructor without having to understand that they must first add themselves to the WindowManager.

      true if transient

    • canBeParent

      public boolean canBeParent()

      Returns:
      true if a snapshot

    • setTransient

      protected void setTransient()
      Sets this class to be transient. Setting this provider to be transient will cause this provider to be removed from the tool when the corresponding window is closed.

    • setWindowMenuGroup

      protected void setWindowMenuGroup(String group)
      Sets the window menu group. If the window menu group is null, the corresponding window menu item will appear in the root menu, otherwise it will appear in a sub-menu named group.
      Parameters:
      group - the name of the window's sub-menu for this provider

    • getDefaultWindowPosition

      public WindowPosition getDefaultWindowPosition()
      The initial WindowPosition of this provider. If a window group is provided, then this position is relative to that provider. Otherwise, this position is relative to the tool window.
      Returns:
      The initial WindowPosition of this provider.

    • setDefaultWindowPosition

      protected void setDefaultWindowPosition(WindowPosition windowPosition)
      Sets the default position of this provider when being shown for the first time. If the providers position in the tool has been saved before, then this value is ignored.
      Parameters:
      windowPosition - the position
      See Also:

    • getIntraGroupPosition

      public WindowPosition getIntraGroupPosition()
      The position of this provider when being placed with other members of the same group. As an example, assume this provider is being shown for the first time while there is another member of its window group already visible. Further, assume that this method will return WindowPosition.STACK. This provider will then be stacked upon the already showing provider.

      To determine where this provider should be initially shown, see getDefaultWindowPosition().

      Returns:
      The position of this provider when being placed with other members of the same group.

    • setIntraGroupPosition

      public void setIntraGroupPosition(WindowPosition position)
      See getIntraGroupPosition().
      Parameters:
      position - the new position

    • getWindowGroup

      public String getWindowGroup()
      Returns an optional group designator that, if non-null, the docking window manager uses to determine the initial location of the new component relative to any existing instances of this component Provider.

      The docking window manager will use Intra-group Position to decide where to place this provider inside of the already open instances of the same group. The default position is 'stack', which results in the new instance being stacked with other instances of this provider that have the same group unless that instance is the active provider or is currently stacked with the active provider. (This is to prevent new windows from covering the active window).

      Returns:
      the window group

    • setWindowGroup

      protected void setWindowGroup(String group)
      Sets the window group. See getWindowGroup().

      Parameters:
      bigger - if true, the font should be made bigger, otherwise the font should be made smaller

    • resetFontSize
