The StackPanel control is a container which can be used to hold children elements which can be stacked either horizontally or vertically.

Layout Requirements

Unlike other FlatRedBall.Forms controls, the StackPanel does not use a Gum runtime object from the existing project. Rather, the StackLayout is itself an invisible control which can contain other objects.

Note that even though the StackLayout doesn’t use a component defined in your Gum project, it still has a backing Visual object so it can be added to any other FlatRedBall.Forms object and it has full support for all Gum variables such as position and size.

Code Example

The following code creates a StackLayout, sets it to be drawn (meaning its children will be drawn), then uses AddChild to add four buttons.


The Orientation property sets whether children stack horizontally or vertically. The default value is Orientation.Vertical. The following code shows how to change the orientation to Horizontal.
