str
- The stringpublic static int getLeadingWhiteSpace(java.lang.CharSequence str)
str
- The stringpublic static int getTrailingWhiteSpace(java.lang.String str)
str
- The stringpublic static int getLeadingWhiteSpaceWidth(java.lang.String str, int tabSize)
str
- The stringtabSize

str
- The stringtabSize
- The tab sizepublic static java.lang.String createWhiteSpace(int len, int tabSize)
To get a whitespace string tuned to the current buffer's settings, call this method as follows:
myWhitespace = MiscUtilities.createWhiteSpace(myLength, (buffer.getBooleanProperty("noTabs") ? 0 : buffer.getTabSize()));
len
- The lengthtabSize
- The tab size, or 0 if tabs are not to be usedpublic static java.lang.String truncateWhiteSpace(int len, int tabSize, java.lang.String indentStr)
public static java.lang.String createWhiteSpace(int len, int tabSize, int start)
To get a whitespace string tuned to the current buffer's settings, call this method as follows:
myWhitespace = MiscUtilities.createWhiteSpace(myLength, (buffer.getBooleanProperty("noTabs") ? 0 : buffer.getTabSize()));
len
- The lengthtabSize
- The tab size, or 0 if tabs are not to be usedstart
- The start offset, for tab alignmentpublic static int getVirtualWidth(javax.swing.text.Segment seg, int tabSize)
seg
- The segmenttabSize
- The tab sizepublic static int getOffsetOfVirtualColumn(javax.swing.text.Segment seg, int tabSize, int column, int[] totalVirtualWidth)
seg
