It is a good idea. Sandro Cumerlato was planning for something similar, a white background and clicking anywhere on a selected row would change the state. Please communicate with him if you plan to implement it. You both are custom component wizards. Lazarus 1.4 will be forked soon (1-2 months). A realistic plan is to leave the current checkbox there for 1.4 and put the new one in trunk. The current solution works well, too. Bart, we must do custom painting without widgetset overhead for the non-selected rows in OI. There can be tens of published booleans in a component and OI must be snappy. Juha
