    Specifies the screen location of the layer manager, relative to it's frame center. May be null. If this value is non-null, it overrides the position specified by #setPosition. The location is specified in pixels. The origin is the window's lower left corner. Positive X values are to the right of the origin, positive Y values are upwards from the origin. The final frame location will be affected by the currently specified location offset if a non-null location offset has been specified (see setLocationOffset(Vec4)).
    
    Parameters:

    Parameters:
    
    locationOffset - the number of pixels to shift the layer manager frame from its specified screen position. A positive X value shifts the frame to the right. A positive Y value shifts the frame up. If null, no offset is applied. The default offset is null.

  - isMinimized
```
public boolean isMinimized()
```
    Determines whether the layer list frame is minimized. When minimized, the layer list only contains itself as the only item, and thus shrinks toward it's corner position.

    true if the layer list frame is minimized.
  - setMinimized
```
public void setMinimized(boolean minimized)

    Returns:
    
    true if the layer list can be moved or dragged with the mouse cursor.
  - setComponentDragEnabled
```
public void setComponentDragEnabled(boolean enabled)
```
    Sets whether the layer list can be moved or dragged with the mouse cursor.
    If enabled, dragging the frame will result in a change to it's location offset - setLocationOffset(Vec4). If the list is also set to snap to corners - setSnapToCorners(boolean), the frame position may change so as to be attached to the nearest corner - see setPosition(String).
    
    Parameters:
    
    enabled - true if the layer list can be moved or dragged with the mouse cursor.
  - isLayerDragEnabled
```
public boolean isLayerDragEnabled()
```
    Determines whether a layer can be moved or dragged within the list with the mouse cursor. If enabled, layers can be moved up and down the list.

    Dragging the layer list frame will result in a change to it's location offset - setLocationOffset(Vec4). If the list is also set to snap to corners - setSnapToCorners(boolean), the frame position may change so as to be attached to the nearest corner - see setPosition(String).
    
    Returns:
    
    true if the layer list snaps to the viewport sides and corners while being dragged.
  - setSnapToCorners
```
