Constructor Detail

BasicGraphicsUtils

public BasicGraphicsUtils()
Constructor. It is utterly unclear why this class should be constructable, but this is what the API specification says.

Compatibility with the Sun reference implementation: The Sun reference implementation seems to ignore the x and y arguments, at least in JDK 1.3.1 and 1.4.1_01. The method always draws the rectangular area at location (0, 0). A bug report has been filed with Sun; its “bug ID” is 4880003. The GNU Classpath implementation behaves correctly, thus not replicating this bug.

drawString

public static void drawString(java.awt.Graphics g,
                              java.lang.String text,
                              int underlinedChar,
                              int x,
                              int y)
Draws a String at the given location, underlining the first occurence of a specified character. The algorithm for determining the underlined position is not sensitive to case. If the character is not part of text, the text will be drawn without underlining. Drawing is performed in the current color and font of g.

drawStringUnderlineCharAt

public static void drawStringUnderlineCharAt(java.awt.Graphics g,
                                             java.lang.String text,
                                             int underlinedIndex,
                                             int x,
                                             int y)
Draws a String at the given location, underlining the character at the specified index. Drawing is performed in the current color and font of g.

drawDashedRect

public static void drawDashedRect(java.awt.Graphics g,
                                  int x,
                                  int y,
                                  int width,
                                  int height)
Draws a rectangle, simulating a dotted stroke by painting only every second pixel along the one-pixel thick edge. The color of those pixels is the current color of the Graphics g. Any other pixels are left unchanged.

getPreferredButtonSize

public static java.awt.Dimension getPreferredButtonSize(javax.swing.AbstractButton b,
                                                        int textIconGap)
Determines the preferred width and height of an AbstractButton, given the gap between the button’s text and icon.
