      • getPreferredScrollableViewportSize

        public java.awt.Dimension getPreferredScrollableViewportSize()
        Returns the preferred size of the viewport if this component is embedded in a JScrollPane. This uses the desired column and row settings if they have been set, otherwise the superclass behavior is used.
        Specified by:
        getPreferredScrollableViewportSize in interface javax.swing.Scrollable
        Overrides:
        getPreferredScrollableViewportSize in class javax.swing.text.JTextComponent
        Returns:
        The preferredSize of a JViewport whose view is this Scrollable.
        See Also:
        JComponent.getPreferredSize()
      • getPreferredSize

        public java.awt.Dimension getPreferredSize()
        Returns the preferred size of the TextArea. This is the maximum of the size needed to display the text and the size requested for the viewport.
        Overrides:
        getPreferredSize in class javax.swing.JEditorPane
        Returns:
        the size
      • getColumnWidth

        protected int getColumnWidth()
        Gets column width. The meaning of what a column is can be considered a fairly weak notion for some fonts. This method is used to define the width of a column. By default this is defined to be the width of the character m for the font used. This method can be redefined to be some alternative amount.
        Returns:
        the column width >= 1
      • getRowHeight

        protected int getRowHeight()
        Defines the meaning of the height of a row. This defaults to the height of the font.
        Returns:
        the height >= 1
