    • Constructor Detail

      • JEditorArea

        public JEditorArea()
        Creates a new instance.

    • Method Detail

      • getStyledEditorKit

        public javax.swing.text.StyledEditorKit getStyledEditorKit()

      • setLineWrap

        public void setLineWrap(boolean newValue)
        Sets the line-wrapping policy of the text area. If set to true the lines will be wrapped if they are too long to fit within the allocated width. If set to false, the lines will always be unwrapped. A PropertyChange event ("lineWrap") is fired when the policy is changed. By default this property is false.
        Parameters:
        newValue - indicates if lines should be wrapped
        See Also:
        getLineWrap()

      • getLineWrap

        public boolean getLineWrap()
        Gets the line-wrapping policy of the text area. If set to true the lines will be wrapped if they are too long to fit within the allocated width. If set to false, the lines will always be unwrapped.
        Returns:
        if lines will be wrapped

      • getScrollableTracksViewportWidth

        public boolean getScrollableTracksViewportWidth()
        Returns true if a viewport should always force the width of this Scrollable to match the width of the viewport. This is implemented to return true if the line wrapping policy is true, and false if lines are not being wrapped.
        Specified by:
        getScrollableTracksViewportWidth in interface javax.swing.Scrollable
        Overrides:
        getScrollableTracksViewportWidth in class javax.swing.JEditorPane
        Returns:
        true if a viewport should force the Scrollables width to match its own.

      • rebuildView

        public void rebuildView()

      • replaceRange

        public void replaceRange(java.lang.String str,
                         int start,
                         int end)
        Replaces text from the indicated start to end position with the new text specified. Does nothing if the model is null. Simply does a delete if the new string is null or empty.

        This method is thread safe, although most Swing methods are not. Please see Threads and Swing for more information.

        Parameters:
        str - the text to use as the replacement
        start - the start position >= 0
        end - the end position >= start
        Throws:
        java.lang.IllegalArgumentException - if part of the range is an invalid position in the model

      • getLineOfOffset

        public int getLineOfOffset(int offset)
                    throws javax.swing.text.BadLocationException
        Translates an offset into the components text to a line number.
        Parameters:
        offset - the offset >= 0
        Returns:
        the line number >= 0
        Throws:
        javax.swing.text.BadLocationException - thrown if the offset is less than zero or greater than the document length.

      • getLineStartOffset

        public int getLineStartOffset(int line)
                       throws javax.swing.text.BadLocationException
        Determines the offset of the start of the given line.
        Parameters:
        line - the line number to translate >= 0
        Returns:
        the offset >= 0
        Throws:
        javax.swing.text.BadLocationException - thrown if the line is less than zero or greater or equal to the number of lines contained in the document (as reported by getLineCount).
