All Implemented Interfaces:

IThemeExtension

Direct Known Subclasses:

ModernHierarchicalTreeLayerThemeExtension
```
public class DefaultHierarchicalTreeLayerThemeExtension
extends Object
implements IThemeExtension
```
IThemeExtension that adds styling configurations for the HierarchicalTreeLayer.
The theme styling for the HierarchicalTreeLayer is implemented as a IThemeExtension because the styling configurations for trees collide with the default tree styling configurations. It is not possible to combine the styling of a standard tree and a hierarchical tree.

Since:

2.0

    Description copied from interface: IThemeExtension
    
    Method that is used to create the painter instances that should be registered for styling. Needed to update painters in case zoom operations
    
    Specified by:
    
    createPainterInstances in interface IThemeExtension
  - registerStyles
```
public void registerStyles(IConfigRegistry configRegistry)
```
    Description copied from interface: IThemeExtension
    
    Register the style configurations that should be added by this IThemeExtension.
    
    Specified by:
    
    registerStyles in interface IThemeExtension
    
    Parameters:
    
    configRegistry - The IConfigRegistry that is used by the NatTable instance to which the style configurations should be registered.
  - configureDefaultStyle
```
protected void configureDefaultStyle(IConfigRegistry configRegistry)
```
    Register default style configurations. Typically these configurations are used be the body region and will be overridden by more specific configurations of the header regions or custom styling based on labels.
    It is necessary to override the default configuration provided by the base ThemeConfiguration to render the hierarchical representation correctly. Especially the horizontal and vertical alignment need to be adjusted from the default.
    
    Parameters:
    
    configRegistry - The IConfigRegistry that is used by the NatTable instance to which the style configuration should be applied to.
  - getDefaultCellStyle
```
protected IStyle getDefaultCellStyle()
```
    Returns:
    
    The IStyle that should be used by default to render NatTable.
  - getDefaultCellPainter
```
protected ICellPainter getDefaultCellPainter()
```
    Returns the default ICellPainter that is used to render the NatTable.
    Typically this ICellPainter is used to render the body region and is overridden for other regions or other custom styling configurations based on labels.
    
    Returns:
    
    The ICellPainter that should be used by default to render NatTable.
  - configureTreeStyle
```
protected void configureTreeStyle(IConfigRegistry configRegistry)
```
    This method is used to register style configurations for a tree representation. It will only be applied in case a TreeLayer is involved, which adds the configuration label TreeLayer.TREE_COLUMN_CELL to the tree column.
    
    Parameters:
    
    configRegistry - The IConfigRegistry that is used by the NatTable instance to which the style configuration should be applied to.
  - configureLevelHeaderStyle
```
protected void configureLevelHeaderStyle(IConfigRegistry configRegistry)
```
    By default the levels in a HierarchicalTreeLayer are separated by additional level header columns. Those columns are marked with the label HierarchicalTreeLayer.LEVEL_HEADER_CELL. In this method the styling for those cells can be configured.
    
    Parameters:
    
    configRegistry - The IConfigRegistry that is used by the NatTable instance to which the style configuration should be applied to.
  - configureAlternatingRowStyle
```
protected void configureAlternatingRowStyle(IConfigRegistry configRegistry)
```
    When creating a HierarchicalTreeLayer, using the DefaultHierarchicalTreeLayerConfiguration, the HierarchicalTreeAlternatingRowConfigLabelAccumulator is configured for the body region to apply labels for alternating rows. It applies the following labels for which this method registers styles:
    
    AlternatingRowConfigLabelAccumulator.EVEN_ROW_CONFIG_TYPE
    
    AlternatingRowConfigLabelAccumulator.EVEN_ROW_CONFIG_TYPE
    
    If the HierarchicalTreeAlternatingRowConfigLabelAccumulator is not configured, this style configuration will have no effect.
    Parameters:
    
    configRegistry - The IConfigRegistry that is used by the NatTable instance to which the style configuration should be applied to.
  - getTreeCellPainter
```
protected ICellPainter getTreeCellPainter()
```

    That means this ICellPainter is registered against DisplayMode.NORMAL and the configuration label TreeLayer.TREE_COLUMN_CELL.
    
    Returns:
    
    The ICellPainter that should be used to render the tree column in a NatTable.
  - getTreeSelectionCellPainter
```
protected ICellPainter getTreeSelectionCellPainter()
```
    Returns the ICellPainter that should be used to render the selected tree column cells in a NatTable.
    That means this ICellPainter is registered against DisplayMode.SELECT and the configuration label TreeLayer.TREE_COLUMN_CELL.
    
    Returns:
    
    The ICellPainter that should be used to render the selected tree column in a NatTable.
  - getTreeStructurePainter
```
protected ICellPainter getTreeStructurePainter()
```
    Returns the ICellPainter that should be used to render the tree structure in a NatTable. It needs to be an IndentedTreeImagePainter to show the expand/collapsed state aswell as the indentation for the tree level. It that can be wrapped with several CellPainterWrapper. If there is no IndentedTreeImagePainter in the painter hierarchy, this configuration attribute will be ignored by the TreeLayer.
    
    Returns:
    
    The IndentedTreeImagePainter that should be used to render the tree structure in a NatTable.
  - getTreeStructureSelectionPainter
```
protected ICellPainter getTreeStructureSelectionPainter()
```
    Returns the ICellPainter that should be used to render the selected tree structure in a NatTable. It needs to be an IndentedTreeImagePainter to show the expand/collapsed state aswell as the indentation for the tree level. It that can be wrapped with several CellPainterWrapper. If there is no IndentedTreeImagePainter in the painter hierarchy, this configuration attribute will be ignored by the TreeLayer.
    
    Returns:
    
    The IndentedTreeImagePainter that should be used to render the selected tree structure in a NatTable.
  - getCollapsedChildPainter
```
protected ICellPainter getCollapsedChildPainter()
```
    Returns the ICellPainter that should be used to render the content in cells of collapsed childs, e.g. an empty painter to paint empty cells.
    That means this ICellPainter is registered against DisplayMode.NORMAL and the configuration label HierarchicalTreeLayer.COLLAPSED_CHILD.
    
    Returns:
    
    The ICellPainter that should be used to render the tree column in a NatTable.
  - getTreeStyle
```
protected IStyle getTreeStyle()
```
    Returns the IStyle that should be used to render the tree column cells in a NatTable.
    That means this IStyle is registered against DisplayMode.NORMAL and the configuration label TreeLayer.TREE_COLUMN_CELL.
    
    If this method returns null, no value will be registered to keep the IConfigRegistry clean. The result would be the same, as if no value is found in the IConfigRegistry. In this case the rendering will fallback to the default configuration.
    
    Returns:
    
    The IStyle that should be used to render the tree column in a NatTable.
  - getTreeSelectionStyle

    If this method returns null, no value will be registered to keep the IConfigRegistry clean. The result would be the same, as if no value is found in the IConfigRegistry. In this case the rendering will fallback to the default configuration.
    
    Returns:
    
    The IStyle that should be used to render the selected tree column in a NatTable.
  - getLevelHeaderStyle

    If this method returns null, no value will be registered to keep the IConfigRegistry clean. The result would be the same, as if no value is found in the IConfigRegistry. In this case the rendering will fallback to the default configuration.
    
    Returns:
    
    The IStyle that should be used to render the tree column in a NatTable.
  - getLevelHeaderCellPainter
```
protected ICellPainter getLevelHeaderCellPainter()
