public class Utilities

extends Object

Utilities()

drawTabbedText(Segment, int, int, Graphics, TabExpander, int)

Draws the given text, expanding any tabs that are contained using the given tab expansion technique.

getTabbedTextOffset(Segment, FontMetrics, int, int, TabExpander, int)

Determines the relative offset into the given text that best represents the given span in the view coordinate system.

getTabbedTextWidth(Segment, FontMetrics, int, TabExpander, int)

Determines the width of the given segment of text taking tabs into consideration.

 public Utilities()

 public static final int drawTabbedText(Segment s,
                                        int x,
                                        int y,
                                        Graphics g,
                                        TabExpander e,
                                        int startOffset)

Draws the given text, expanding any tabs that are contained using the given tab expansion technique. This particular implementation renders in a 1.1 style coordinate system where ints are used and 72dpi is assumed.

Parameters:

s - the source of the text

x - the X origin

y - the Y origin

g - the graphics context

e - how to expand the tabs

startOffset - starting offset in the document of the text

Returns:

s the location at the end of the rendered text

 public static final int getTabbedTextWidth(Segment s,
                                            FontMetrics metrics,
                                            int x,
                                            TabExpander e,
                                            int startOffset)

Determines the width of the given segment of text taking tabs into consideration. This is implemented in a 1.1 style coordinate system where ints are used and 72dpi is assumed.

Parameters:

s - the source of the text

metrics - the font metrics to use for the calculation

x - the X origin

e - how to expand the tabs

startOffset - starting offset in the document of the text

Returns:

s the width of the text

 public static final int getTabbedTextOffset(Segment s,
                                             FontMetrics metrics,
                                             int x0,
                                             int x,
                                             TabExpander e,
                                             int startOffset)

Determines the relative offset into the given text that best represents the given span in the view coordinate system. This is implemented in a 1.1 style coordinate system where ints are used and 72dpi is assumed.

Parameters:

s - the source of the text

metrics - the font metrics to use for the calculation

x0 - the starting view location representing the start of the given text.

x - the target view location to translate to an offset into the text.

e - how to expand the tabs

startOffset - starting offset in the document of the text

Returns:

s the offset into the text
