/**

* @defgroup Grid Grid
|
|
*
|
|
* The grid is a grid layout widget that lays out a series of children as a
|
|
* fixed "grid" of widgets using a given percentage of the grid width and
|
|
* height each using the child object.
|
|
*
|
|
* The Grid uses a "Virtual resolution" that is stretched to fill the grid
|
|
* widgets size itself. The default is 100 x 100, so that means the
|
|
* position and sizes of children will effectively be percentages (0 to 100)
|
|
* of the width or height of the grid widget
|
