Method Details

centerDialog

public static void centerDialog(JDialog dialog)

Center a dialog

Parameters:

dialog - the dialog to center

upperRightComponent

public static void upperRightComponent(Component component,
 int dh,
 int dv)

Place a component in the upper right

Parameters:

component - The Component to center.

padString

public static String padString(Component c,
 String inp,
 String tstr)

Convenience routine for padding a string using the default font.

Pads inp with trailing spaces so that, when rendered in c's font, its pixel width approximates tstr's pixel width as closely as possible (adding one space at a time until the width gap stops shrinking).

Parameters:

c - the component supplying the font metrics used to measure pixel widths

inp - the string to be padded; null is treated as empty

tstr - the target string-- try to return a string that renders at about the same pixel width

Returns:

inp (or the empty string) with zero or more trailing spaces appended

paddedPanel

public static JPanel paddedPanel(int hpad,
 int vpad,
 Component component)

Create a nice padded panel.

Parameters:

hpad - the pixel pad on the left and right

vpad - the pixel pad on the top and bottom

component - the main component placed in the center.

Returns:

the padded panel

yesNoDialog

public static int yesNoDialog(String prompt,
 String... options)

Create a dialog with a prompt and a set of options

Parameters:

prompt - the message displayed to the user

options - the available response labels

Returns:

the selected option index, or -1 if the dialog was closed

requestDetailsView

public static void requestDetailsView(JFileChooser chooser)

Attempts to place a file chooser in details view.

This relies on a look-and-feel action name and therefore is not guaranteed to work with every Swing look and feel.

Parameters:

chooser - the file chooser
