    • Method Detail

      • getTree

        public JXTree getTree()
      • hasFocus

        public boolean hasFocus()
        Returns true if the cell identified by this adapter currently has focus. Otherwise, it returns false.
        Specified by:
        hasFocus in class ComponentAdapter
        Returns:
        true if the cell identified by this adapter currently has focus; Otherwise, return false
      • getValueAt

        public java.lang.Object getValueAt​(int row,
                                           int column)
        Returns the value of the target component's cell identified by the specified row and column in model coordinates.
        Specified by:
        getValueAt in class ComponentAdapter
        Parameters:
        row - in model coordinates
        column - in model coordinates
        Returns:
        the value of the target component's cell identified by the specified row and column
      • getStringAt

        public java.lang.String getStringAt​(int row,
                                            int column)
        Returns the String representation of the value of the cell identified by the row specified row and column in model coordinates.

        This implementation messages the StringValue.TO_STRING with the valueAt, subclasses should re-implement and use the api appropriate for the target component type.

        Overrides:
        getStringAt in class ComponentAdapter
        Parameters:
        row - in model coordinates
        column - in model coordinates
        Returns:
        the value of the target component's cell identified by the specified row and column
      • getCellBounds

        public java.awt.Rectangle getCellBounds()
        Returns the bounds of the cell identified by this adapter.

        Overrides:
        getCellBounds in class ComponentAdapter
        Returns:
        the bounds of the cell identified by this adapter
      • isEditable

        public boolean isEditable()
        Returns true if the cell identified by this adapter is editable, false otherwise.
        Specified by:
        isEditable in class ComponentAdapter
        Returns:
        true if the cell is editable, false otherwise
      • isSelected

        public boolean isSelected()
        Returns true if the cell identified by this adapter is currently selected. Otherwise, it returns false.
        Specified by:
        isSelected in class ComponentAdapter
        Returns:
        true if the cell identified by this adapter is currently selected; Otherwise, return false
      • isExpanded

        public boolean isExpanded()
        Returns true if the cell identified by this adapter is currently expanded. Otherwise, it returns false. For components that do not support hierarchical data, this method always returns true because the cells in such components can never be collapsed.
        Overrides:
        isExpanded in class ComponentAdapter
        Returns:
        true if the cell identified by this adapter is currently expanded; Otherwise, return false
      • getDepth

        public int getDepth()
        Returns the depth of this row in the hierarchy where the root is 0. For components that do not contain hierarchical data, this method returns 1.
        Overrides:
        getDepth in class ComponentAdapter
        Returns:
        the depth for this adapter
      • isHierarchical

        public boolean isHierarchical()
        Returns true if the cell identified by this adapter displays the hierarchical node. Otherwise, it returns false. For components that do not support hierarchical data, this method always returns false because the cells in such components can never have children.
        Overrides:
        isHierarchical in class ComponentAdapter
        Returns:
        true if the cell identified by this adapter displays the hierarchical node; Otherwise, return false
      • isLeaf

        public boolean isLeaf()
        Returns true if the cell identified by this adapter is a leaf node. Otherwise, it returns false. For components that do not support hierarchical data, this method always returns true because the cells in such components can never have children.
        Overrides:
        isLeaf in class ComponentAdapter
        Returns:
        true if the cell identified by this adapter is a leaf node; Otherwise, return false
      • isCellEditable

        public boolean isCellEditable​(int row,
                                      int column)
        Determines whether this cell is editable.
        Specified by:
        isCellEditable in class ComponentAdapter
        Parameters:
        row - the row to query in model coordinates
        column - the column to query in model coordinates
        Returns:
        true if the cell is editable, false otherwise
