PHP Class Prado\Web\UI\WebControls\TCheckBoxList

TCheckBoxList displays a list of checkboxes on a Web page. The layout of the checkbox list is specified via {@link setRepeatLayout RepeatLayout}, which can be either 'Table' (default) or 'Flow'. A table layout uses HTML table cells to organize the checkboxes while a flow layout uses line breaks to organize the checkboxes. When the layout is using 'Table', {@link setCellPadding CellPadding} and {@link setCellSpacing CellSpacing} can be used to adjust the cellpadding and cellpadding of the table. The number of columns used to display the checkboxes is specified via {@link setRepeatColumns RepeatColumns} property, while the {@link setRepeatDirection RepeatDirection} governs the order of the items being rendered. The alignment of the text besides each checkbox can be specified via {@link setTextAlign TextAlign}.
