• equals

  public static boolean equals(Object o1, Object o2)

  Checks if the two objects equal. If both are null, they are equal. If o1 and o2 both are Comparable, we will use compareTo method to see if it equals 0. At last, we will use o1.equals(o2) to compare. If none of the above conditions match, we return false.

  Parameters:

  o1 - the first object to compare

  o2 - the second object to compare

  Returns:

  true if the two objects are equal. Otherwise false.

• equals

  public static boolean equals(Object o1, Object o2, boolean considerArrayOrList)

  Checks if the two objects equal. If both are the same instance, they are equal. If both are null, they are equal. If o1 and o2 both are Comparable, we will use compareTo method to see if it equals 0. If considerArrayOrList is true and o1 and o2 are both array, we will compare each element in the array. At last, we will use o1.equals(o2) to compare. If none of the above conditions match, we return false.

  Parameters:

  o1 - the first object to compare

  o2 - the second object to compare

  considerArrayOrList - If true, and if o1 and o2 are both array, we will compare each element in the array instead of just compare the two array objects.

  Returns:

  true if the two objects are equal. Otherwise false.

• equals

  public static boolean equals(Object o1, Object o2, boolean considerArrayOrList, boolean caseSensitive)

  Checks if the two objects equal. If both are the same instance, they are equal. If both are null, they are equal. If o1 and o2 both are Comparable, we will use compareTo method to see if it equals 0. If considerArrayOrList is true and o1 and o2 are both array, we will compare each element in the array. At last, we will use o1.equals(o2) to compare. If none of the above conditions match, we return false.

  Parameters:

  o1 - the first object to compare

  o2 - the second object to compare

  considerArrayOrList - If true, and if o1 and o2 are both array, we will compare each element in the array instead of just compare the two array objects.

  caseSensitive - if the o1 and o2 are CharSequence, we will use this parameter to do a case sensitive or insensitive comparison

  Returns:

  true if the two objects are equal. Otherwise false.

• getFasterScaledInstance

  public static BufferedImage getFasterScaledInstance(BufferedImage img, int targetWidth, int targetHeight, Object hint, boolean progressiveBilinear)

  Convenience method that returns a scaled instance of the provided BufferedImage.

  Parameters:

  img - the original image to be scaled

  targetWidth - the desired width of the scaled instance, in pixels

  targetHeight - the desired height of the scaled instance, in pixels

  hint - one of the rendering hints that corresponds to RenderingHints.KEY_INTERPOLATION (e.g. RenderingHints.VALUE_INTERPOLATION_NEAREST_NEIGHBOR, RenderingHints.VALUE_INTERPOLATION_BILINEAR, RenderingHints.VALUE_INTERPOLATION_BICUBIC)

  progressiveBilinear - if true, this method will use a multi-step scaling technique that provides higher quality than the usual one-step technique (only useful in down-scaling cases, where targetWidth or targetHeight is smaller than the original dimensions)

  Returns:

  a scaled version of the original BufferedImage

• getFocusAcceleratorKeyMask

  public static int getFocusAcceleratorKeyMask()

• shouldUseSystemFont

  public static boolean shouldUseSystemFont()

  In JDK1.4, it uses a wrong font for Swing component in Windows Linvalid input: '&F' which is actually one big reason for people to think Swing application ugly. To address this issue, we changed the code to force to use Tahoma font for all the fonts in Linvalid input: '&F' instead of using the system font.

  However this is a downside to this. Tahoma cannot display Unicode characters such as Chinese, Japanese and Korean. So if the locale is CJK (SystemInfo.isCJKLocale(), we shouldn't use Tahoma. If you are on JDK 1.5 and above, you shouldn't force to use Tahoma either because JDK fixed it in 1.5 and above.

  There are also a few system properties you can set to control if system font should be used. "swing.useSystemFontSettings" is the one for all Swing applications. "Application.useSystemFontSettings" is the one for a particular Swing application.

  This method considers all the cases above. If JDK is 1.5 and above, this method will return true. If you are on Chinese, Japanese or Korean locale, it will return true. If "swing.useSystemFontSettings" property us true, it will return true. If "Application.useSystemFontSettings" property is true, it will return true. Otherwise, it will return false. All JIDE Linvalid input: '&F' considered the returned value and decide if Tahoma font should be used or not.

  Last but the least, we also add system property "jide.useSystemfont" which has the highest priority. If you set it to "true" or "false", this method will just check that value and return true or false respectively without looking at any other settings.

  Returns:

  true if the Linvalid input: '&F' should use system font.

  public static Component findSomethingFocusable(Container container)

  Find some subcomponent of the specified container that will accept focus.

  Returns:

  a focusable subcomponent
