protected static class JXTree.TreeAdapter extends ComponentAdapter

  • Constructor Details

    • TreeAdapter

      public TreeAdapter(JXTree component)
      Constructs a TableCellRenderContext for the specified target component.
      Parameters:
      component - the target component

  • Method Details

    • 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 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 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 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
