        public JmriJFrame​(boolean saveSize,
                  boolean savePosition)
        Creates a JFrame with standard settings, optional save/restore of size and position.
        Parameters:

        savePosition - Set true to save the last known location

      • JmriJFrame

        public JmriJFrame()
        Creates a JFrame with standard settings, including saving/restoring of size and position.

      • JmriJFrame

        public JmriJFrame​(java.lang.String name)
        Creates a JFrame with with given name plus standard settings, including saving/restoring of size and position.
        Parameters:
        name - Title of the JFrame

      • JmriJFrame

        public JmriJFrame​(java.lang.String name,
                  boolean saveSize,
                  boolean savePosition)
        Creates a JFrame with with given name plus standard settings, including optional save/restore of size and position.
        Parameters:
        name - Title of the JFrame
        saveSize - Set true to save the last knowm size
        savePosition - Set true to save the last known location

    • Method Detail

      • setFrameTitle

        final void setFrameTitle​(java.lang.String name)

      • makePrivateWindow

        public void makePrivateWindow()
        Remove this window from the Windows Menu by removing it from the list of active JmriJFrames.

      • setFrameLocation

        public void setFrameLocation()
        Reset frame location and size to stored preference value

      • getScreenDimensions

        public static java.util.ArrayList<JmriJFrame.ScreenDimensions> getScreenDimensions()
        returns the previously initialized array of screens. See getScreenDimensionsOnce()
        Returns:
        ArrayList of screen bounds and insets

      • generateWindowRef

        public void generateWindowRef()
        Regenerates the window frame ref that is used for saving and setting frame size and position against.

      • pack

        public void pack()
        Overrides:
        pack in class java.awt.Window

      • undecorate

        public void undecorate()
        Remove any decoration, such as the title bar or close window control, from the JFrame.

        JmriJFrames are often built internally and presented to the user before any scripting action can interact with them. At that point it's too late to directly invoke setUndecorated(true) because the JFrame is already displayable. This method uses dispose() to drop the windowing resources, sets undecorated, and then redisplays the window.

      • reSizeToFitOnScreen

        void reSizeToFitOnScreen()
        Tries to get window to fix entirely on screen. First choice is to move the origin up and left as needed, then to make the window smaller

      • initComponents

        public void initComponents()
        By default, Swing components should be created an installed in this method, rather than in the ctor itself.

      • addHelpMenu

        public final void addHelpMenu​(java.lang.String ref,
                              boolean direct)
        Add a standard help menu, including window specific help item. Final because it defines the content of a standard help menu, not to be messed with individually
        Parameters:
        ref - JHelp reference for the desired window-specific help page
        direct - true if the help main-menu item goes directly to the help system, such as when there are no items in the help menu

      • addWindowCloseShortCut

        void addWindowCloseShortCut()
        Adds a "Close Window" key shortcut to close window on op-W.

      • setEscapeKeyAction

        public void setEscapeKeyAction​(javax.swing.AbstractAction action)
        Bind an action to the Escape key.

        Binds an AbstractAction to the Escape key. If an action is already bound to the Escape key, that action will be replaced. Passing null unbinds any existing actions from the Escape key.

        Note that binding the Escape key to any action may break expected or standardized behaviors. See Keyboard Shortcuts, Mnemonics, and Other Keyboard Operations in the Java Look and Feel Design Guidelines for standardized behaviors.

        Parameters:
        action - The AbstractAction to bind to.
        See Also:
        getEscapeKeyAction(), setEscapeKeyClosesWindow(boolean)

      • setEscapeKeyClosesWindow

        public void setEscapeKeyClosesWindow​(boolean closesWindow)
        Bind the Escape key to an action that closes the window.

        If closesWindow is true, this method creates an action that triggers the "window is closing" event; otherwise this method removes any actions from the Escape key.

        Parameters:
        closesWindow - Create or destroy an action to close the window.
        See Also:
        WindowEvent.WINDOW_CLOSING, setEscapeKeyAction(javax.swing.AbstractAction)

      • getMaximumSize

        public java.awt.Dimension getMaximumSize()
        Provide a maximum frame size that is limited to what can fit on the screen after toolbars, etc are deducted.

        Some of the methods used here return null pointers on some Java implementations, however, so this will return the superclasses's maximum size if the algorithm used here fails.

        Overrides:
        getMaximumSize in class java.awt.Container
        Returns:
        the maximum window size

      • getPreferredSize

        public java.awt.Dimension getPreferredSize()
        The preferred size must fit on the physical screen, so calculate the lesser of either the preferred size from the layout or the screen size.
        Overrides:
        getPreferredSize in class java.awt.Container
        Returns:
        the preferred size or the maximum size, whichever is smaller

      • getFrameList

        @Nonnull
public static java.util.List<JmriJFrame> getFrameList()
        Get a List of the currently-existing JmriJFrame objects. The returned list is a copy made at the time of the call, so it can be manipulated as needed by the caller.
        Returns:
        a list of JmriJFrame instances. If there are no instances, an empty list is returned.

      • getFrameList

        public static <T extends JmriJFrame> java.util.List<T> getFrameList​(@Nonnull
                                                                    java.lang.Class<T> type)
        Get a list of currently-existing JmriJFrame objects that are specific sub-classes of JmriJFrame.

        The returned list is a copy made at the time of the call, so it can be manipulated as needed by the caller.

        Type Parameters:
        T - generic JmriJframe.
        Parameters:
        type - The Class the list should be limited to.
        Returns:
        An ArrayList of Frames.

      • getFrame

        public static JmriJFrame getFrame​(java.lang.String name)
