All Implemented Interfaces:
ICellPainter
public class IndentedTreeImagePainter extends CellPainterWrapper
Implementation of CellPainterWrapper that is used to render tree structures in NatTable. It puts indentation to tree nodes to visualize the tree structure and adds expand/collapse icons corresponding to the state if a tree node has children.

  • Constructor Details

    • IndentedTreeImagePainter

      public IndentedTreeImagePainter()
      Creates an IndentedTreeImagePainter. Will use 10 pixels for indentation per depth and a default TreeImagePainter for rendering the icons in the tree.

    • IndentedTreeImagePainter

      public IndentedTreeImagePainter(int treeIndent)
      Creates an IndentedTreeImagePainter. Will use the given number of pixels for indentation per depth and a default TreeImagePainter for rendering the icons in the tree.
      Parameters:
      treeIndent - The number of pixels to indent per depth.

    • IndentedTreeImagePainter

      public IndentedTreeImagePainter(int treeIndent, ICellPainter treeImagePainter)
      Creates an IndentedTreeImagePainter using the given indentation per depth and ICellPainter for painting the icons in the tree.
      Parameters:
      treeIndent - The number of pixels to indent per depth.
      treeImagePainter - The ICellPainter that should be used to paint the images in the tree. When using the DefaultTreeLayerConfiguration the content painter needs to be of type of TreeImagePainter that paints expand/collapse/leaf icons regarding the node state, because the ui bindings for expand/collapse are registered against that type.
      Since:
      1.6

    • IndentedTreeImagePainter

      public IndentedTreeImagePainter(int treeIndent, CellEdgeEnum cellEdge, ICellPainter treeImagePainter)
      Creates an IndentedTreeImagePainter using the given indentation per depth and ICellPainter for painting the icons in the tree to the specified cell edge.
      Parameters:
      treeIndent - The number of pixels to indent per depth.
      cellEdge - the edge of the cell on which the tree state indicator decoration should be applied
      treeImagePainter - The ICellPainter that should be used to paint the images in the tree. When using the DefaultTreeLayerConfiguration the content painter needs to be of type of TreeImagePainter that paints expand/collapse/leaf icons regarding the node state, because the ui bindings for expand/collapse are registered against that type.
      Since:
      1.6

    • IndentedTreeImagePainter

      public IndentedTreeImagePainter(int treeIndent, ICellPainter interiorPainter, CellEdgeEnum cellEdge, boolean paintBg, int spacing, boolean paintDecorationDependent)
      Creates a IndentedTreeImagePainter that uses the given ICellPainter as base ICellPainter. It will use the TreeImagePainter as decorator for tree state related decorations at the specified cell edge, which can be configured to render the background or not via method parameter. With the additional parameters, the behaviour of the created CellPainterDecorator can be configured in terms of rendering.
      Parameters:
      treeIndent - The number of pixels to indent per depth.
      interiorPainter - the base ICellPainter to use
      cellEdge - the edge of the cell on which the tree state indicator decoration should be applied
      paintBg - flag to configure whether the TreeImagePainter should paint the background or not
      spacing - the number of pixels that should be used as spacing between cell edge and decoration
      paintDecorationDependent - flag to configure if the base ICellPainter should render decoration dependent or not. If it is set to false, the base painter will always paint at the same coordinates, using the whole cell bounds, true will cause the bounds of the cell to shrink for the base painter.

    • IndentedTreeImagePainter

      public IndentedTreeImagePainter(int treeIndent, ICellPainter interiorPainter, CellEdgeEnum cellEdge, ICellPainter decoratorPainter, boolean paintBg, int spacing, boolean paintDecorationDependent)
      Creates a IndentedTreeImagePainter that uses the given ICellPainter as base ICellPainter. It will use the given ICellPainter as decorator for tree state related decorations at the specified cell edge, which can be configured to render the background or not via method parameter. With the additional parameters, the behaviour of the created CellPainterDecorator can be configured in terms of rendering.
      Parameters:
      treeIndent - The number of pixels to indent per depth.
      interiorPainter - the base ICellPainter to use
      cellEdge - the edge of the cell on which the tree state indicator decoration should be applied
      decoratorPainter - the ICellPainter that should be used to paint the tree state related decoration
      paintBg - flag to configure whether the CellPainterDecorator should paint the background or not
      spacing - the number of pixels that should be used as spacing between cell edge and decoration
      paintDecorationDependent - flag to configure if the base ICellPainter should render decoration dependent or not. If it is set to false, the base painter will always paint at the same coordinates, using the whole cell bounds, true will cause the bounds of the cell to shrink for the base painter.

    • IndentedTreeImagePainter

      public IndentedTreeImagePainter(int treeIndent, ICellPainter interiorPainter, boolean paintBg, boolean interiorPainterToSpanFullWidth)
      Creates a IndentedTreeImagePainter that uses the given ICellPainter as base ICellPainter and decorate it with the TreeImagePainter on the right edge of the cell. This constructor gives the opportunity to configure the behaviour of the TreeImagePainter and the CellPainterDecorator for some attributes. Remains because of downwards compatibility.
      Parameters:
      treeIndent - The number of pixels to indent per depth.
      interiorPainter - the base ICellPainter to use
      paintBg - flag to configure whether the TreeImagePainter should paint the background or not
      interiorPainterToSpanFullWidth - flag to configure how the bounds of the base painter should be calculated
