      • setCollapsedIcon

        public static void setCollapsedIcon​(javax.swing.JTree tree,
                                    javax.swing.Icon icon)
        Set's the collapsed icon to use for the given JTree if that tree's UI delegate exetends from BasicTreeUI. If the given tree's UI delegate does not extend from BasicTreeUI then the given tree will not be changed.
        Parameters:
        tree - the tree to set the collapsed icon for.
        icon - the new collapsed icon to use.

        BasicTreeUI.setCollapsedIcon(javax.swing.Icon)

      • setExpandedIcon

        public static void setExpandedIcon​(javax.swing.JTree tree,
                                   javax.swing.Icon icon)
        Set's the expanded icon to use for the given JTree if that tree's UI delegate extends from BasicTreeUI. If the given tree's UI delegate does not extend from BasicTreeUI then the given tree will not be changed.
        Parameters:
        tree - the tree to set the expanded icon for.
        icon - the new collapsed icon to use.

        BasicTreeUI.setExpandedIcon(javax.swing.Icon)

      • setLeftChildIndent

        public static void setLeftChildIndent​(javax.swing.JTree tree,
                                      int indent)
        Set's the left indent in pixels to use for the given JTree's collapsed and expanded icon. This value in conjuction with the right indent comprises the total amount of space that the collapsed and expanded icon draw into. If the given tree's UI delegate does not extend from BasicTreeUI then the given tree will not be changed.
        Parameters:
        tree - the tree to set the left indent for.
        indent - the new left indent in pixels.

        Set's the right indent in pixels to use for the given JTree's collapsed and expanded icon. This value in conjuction with the left indent comprises the total amount of space that the collapsed and expanded icon draw into. If the given tree's UI delegate does not extend from BasicTreeUI then the given tree will not be changed.
        Parameters:

        Parameters:
        tree - the JTree to repaint the selection of.
