- - ### Constructor Detail

    - #### LayerPalette

          public LayerPalette(LayerContainer lc)

      Constructs a new layer palette.
      Parameters:
        `lc` - the layer container that will be controlled by the palette.
      Since:
        1.0

  - ### Method Detail

    - #### isRepaintingImmediately

          public boolean isRepaintingImmediately()

      Determines whether changes to the alpha value of a layer will be shown right away when the user drags the slider knob. The default is TRUE. However, if the Gantt is used to display thousands of timeline objects then it might make sense to disable this feature.
      Returns:
        TRUE if changes to the slider / the alpha value of a layer will be shown even before the user releases the mouse button
      Since:
        1.1

    - #### setRepaintingImmediately

          public void setRepaintingImmediately(boolean immediately)

      Specifies whether changes to the alpha value of a layer will be shown right away when the user drags the slider knob. The default is TRUE. However, if the Gantt is used to display thousands of timeline objects then it might make sense to disable this feature.
      Parameters:
        `immediately` - if TRUE changes to the slider / the alpha value of a layer will be shown even before the user releases the mouse button
      Since:
        1.1

    - #### getMaximumSize

          public Dimension getMaximumSize()

      Overrides:
        `getMaximumSize` in class `JComponent`

    - #### layerContainerChanged

          public void layerContainerChanged(LayerContainerEvent evt)

      Description copied from interface: `ILayerContainerListener`
      The listener's callback method that gets invoked by the `LayerContainer` when the container changes.
      Specified by:
        `layerContainerChanged` in interface `ILayerContainerListener`

    - #### propertyChange

          public void propertyChange(PropertyChangeEvent evt)

      Specified by:
        `propertyChange` in interface `PropertyChangeListener`
