Method Detail

getPointForCentering

public static Point getPointForCentering(Window window)

Returns the Point at which a window should be placed to center that window on the screen.

Some thought was taken as to whether to implement a method such as this, or to simply make a method that, given a window, will center it. It was decided that it is better to not alter an object within a method.

Parameters:
window - The window to calculate the center point for. This object can not be null.
Returns:
the Point at which the window should be placed to center that window on the screen.

getPointForCentering

public static Point getPointForCentering(JInternalFrame window)

Returns the Point at which a window should be placed to center that window on the given desktop.

Some thought was taken as to whether to implement a method such as this, or to simply make a method that, given a window, will center it. It was decided that it is better to not alter an object within a method.

Parameters:
window - The window (JInternalFrame) to calculate the center point for. This object can not be null.
Returns:
the Point at which the window should be placed to center that window on the given desktop

getPointForStaggering

public static Point getPointForStaggering(Window originWindow)

Returns the Point at which a window should be placed in order to be staggered slightly from another "origin" window to ensure that the title areas of both windows remain visible to the user.

Parameters:
originWindow - Window from which the staggered location will be calculated
Returns:
location staggered from the upper left location of the origin window

setConstraints

public static void setConstraints(GridBagConstraints gbc,
                                  int gridx,
                                  int gridy,
                                  int gridwidth,
                                  int gridheight,
                                  double weightx,
                                  double weighty,
                                  int anchor,
                                  int fill,
                                  int top,
                                  int left,
                                  int bottom,
                                  int right)
Utility method used to load a GridBagConstraints object (param gbc) with the data in the other parameters. This method saves code space over doing the assignments by hand, and also allows you to reuse the same GridBagConstraints object reducing temporary object creating (at the expense of a method call. Go figure).


getRectangle

public static Rectangle getRectangle(Window win)
Get a Rectangle object representing the given window's position and magnitude in space.

Parameters:
win - The window to get a Rectangle object for
Returns:
a Rectangle object. @see com.jgui.Rectangle

getRectangle

public static Rectangle getRectangle(JComponent comp)
Get a Rectangle object representing the given JComponent's position and magnitude in space.

Parameters:
comp - The JComponent to get a Rectangle object for
Returns:
a Rectangle object. @see com.jgui.Rectangle

findRootPaneContainer

Parameters:
c -
Returns:
the RootPaneContainer to which the component belongs to

findJFrame

public static JFrame findJFrame(Component c)
Locates the JFrame for the given component

Parameters:
c -
Returns:
the JFrame to which the component belongs to

findJDialog

public static JDialog findJDialog(Component c)
Locates the JDialog for the given component

Parameters:
c -
Returns:
the JDialog to which the component belongs to

setFontRecursively

public static void setFontRecursively(Container c,
                                      Font font)

setMinimumSizeManager

public static void setMinimumSizeManager(Window window,
                                         int minWidth,
                                         int minHeight)
Installs/resets a ComponentListener to resize the given window to minWidth/Height if needed.

Parameters:
