class layout.Column(Widget)A Column is a container widget that arranges its contents in a vertical column. In an OpenGL window, it may contain 3D subwidgets.
The layout is only performed when the widget is initially created; it
is not updated if you add or remove widgets later or change their sizes.
- Column(items, align = 'c', spacing = 10, height = None, expand = None, equalize = '')
The widgets in items are added as subwidgets and arranged vertically with spacing
pixels between. Horizontal alignment is controlled by align, which is one
of 'l', 'c' or 'r' for left, centre or right.
If a height is specified, then expand
may be a widget or an index into the items, and the specified
widget has its height adjusted to fill the remaining space.
Otherwise, the initial size of the Column is calculated from its contents.
If equalize contains 'w', the widths of all the items are made equal to the widest one, and 'lr' is added to their anchor properties. If equalize contains 'h', the heights of all the items are made equal to the tallest one.
