This is the alignment of the widgets in the layout direction.
The alignment has no effect if the widgets can expand to fill the entire box layout.
Set the content alignment for the box layout.
This is the alignment of the widgets in the layout direction.
The alignment has no effect if the widgets can expand to fill the entire box layout.
Get the fit policy for the layout.
The fit policy controls the computed size constraints which are applied to the parent widget by the layout.
Some layout implementations may ignore the fit policy.
Set the fit policy for the layout.
The fit policy controls the computed size constraints which are applied to the parent widget by the layout.
Some layout implementations may ignore the fit policy.
Changing the fit policy will clear the current size constraint for the parent widget and then re-fit the parent.
Test whether the layout is disposed.
Get the parent widget of the layout.
Set the parent widget of the layout.
This is set automatically when installing the layout on the parent widget. The parent widget should not be set directly by user code.
Get the inter-element spacing for the box layout.
Set the inter-element spacing for the box layout.

The index at which to insert the widget.
The widget to insert into the layout.
The index will be clamped to the bounds of the widgets.
If the widget is already added to the layout, it will be moved.
An index which is non-integral.

The default implementation of this method forwards the message to all widgets. It assumes all widget nodes are attached to the parent widget node.
This may be reimplemented by subclasses as needed.

Protected onRemove a widget from the layout.
The widget to remove from the layout.
A widget is automatically removed from the layout when its parent
is set to null. This method should only be invoked directly when
removing a widget from a layout which has yet to be installed on a
parent widget.
This method does not modify the widget's parent.
Remove the widget at a given index from the layout.
The index of the widget to remove.
A widget is automatically removed from the layout when its parent
is set to null. This method should only be invoked directly when
removing a widget from a layout which has yet to be installed on a
parent widget.
This method does not modify the widget's parent.
An index which is non-integral.
