class PASCALIMPLEMENTATION TLayout : public Fmx::Controls::TControl
A layout is a container for other graphical objects.
Use the layouts when you need to organize multiple graphical controls under the same parent.
For instance, you can use these layouts when you need to create rich FireMonkey applications with many graphical controls that are grouped on the same layer. You can set the visibility of all the controls on a layout at once by affecting the visibility of the layout.
