A button grid is a transparent object that is placed on top of a graphic. The graphic should depict a row-by-column array. When one of the graphics is clicked on, it will have a sunken or pressed appearance:
You can use a button grid object to determine where the user clicks on the graphic. The object method would use the
On Clicked event and take appropriate action depending on the location of the click.

In 4D, a button grid is used as a color palette:
Usar grades de botões
The buttons on the grid are numbered from top left to bottom right. In the above example, the grid is 16 columns across by 16 rows down. The button in the top-left position returns 1 when clicked. If the red button at the far right of the second row is selected, the button grid returns 32. If no element is selected, the value is 0
Ir para página
You can assign the
gotoPage standard action to a button grid. When this action is selected, 4D will automatically display the page of the form that corresponds to the number of the button that is selected in the button grid. For example, if the user selects the tenth button of the grid, 4D will display the tenth page of the current form (if it exists).
