Grids

GridLayout

Lazarus component, to arrange components in a grid: rows, columns, width in columns, height in rows. It looks a bit more compatible to Delphi's [https://docwiki.embarcadero.com/Libraries/Sydney/en/Vcl.ExtCtrls.TGridPanel TGridPanel], though not completely (e.g. some properties are named differently, the control collection is [https://docwiki.embarcadero.com/Libraries/Sydney/en/Vcl.ExtCtrls.TControlItem TControlItem] instead of TGridPanelControl, and the later misses some [https://docwiki.embarcadero.com/Libraries/Sydney/en/Vcl.ExtCtrls.TControlItem_Properties properties] as well).
