Method Details

preferredWidth

public static int preferredWidth(int minimumWidth,
 Component... components)

Return the greatest preferred width among a baseline and components.

preferredSizeAtLeast

public static Dimension preferredSizeAtLeast(Component component,
 int minimumWidth,
 int minimumHeight)

Return a component's preferred size enlarged to the given baselines.

fontHeight

public static int fontHeight(Component component,
 Font font,
 int verticalPadding)

Return rendered font height plus total vertical padding.

textWidth

public static int textWidth(Component component,
 String text,
 int horizontalPadding)

Return the rendered width of text plus total horizontal padding.

textColumnWidth

public static int textColumnWidth(Component component,
 int columns,
 int minimumWidth,
 int horizontalPadding)

Return a conservative rendered width for a number of text columns.

iconButtonSize

public static Dimension iconButtonSize(Icon icon,
 Insets margins,
 Dimension minimum)

Return an icon-safe size including margins and a minimum baseline.

requiredHorizontalToolbarHeight

public static int requiredHorizontalToolbarHeight(JToolBar toolbar)

Return the minimum height that can contain every visible component in a horizontal toolbar, including the toolbar's border insets.

Parameters:

toolbar - toolbar to measure, or null

Returns:

minimum safe height, at least one pixel

availableDesktopWidth

public static int availableDesktopWidth(JInternalFrame frame)

Return usable width to the right of an internal frame within its virtual desktop column.

MDI implements virtual columns by offsetting frame X coordinates by whole desktop widths. Consequently, an off-screen frame can have a very large positive or negative X coordinate. Reducing that coordinate modulo the desktop width recovers its column-local position.
