Hello Daniel, Thank you very much for your code. It works pretty well for me. However, I have three questions for you 1> Should we call "check->create();" in CheckTableItem::CheckTableItem Without changing your code, I use the following statement to insert a new cell. table->setItem(2,1, new CheckTableItem(table, NULL, NULL)); After I run the application, the warning message as follows is shown, FXCheckButton::create trying to create window before creating parent window After I comment out the line "check->create();", the code works great 2> Why should we call the following statement in the function onCheck Target->handle(this, FXSEL(SEL_REPLACED,Selector), &tablerange); 3> The return of the function getCheck may be changed as FXuchar. Thank you again for your kindness to share your code. -Feng From: Daniel Stine <robodanny@...> To: foxgui-users@...

I subclassed FXTableItem and embedded a real FXCheckbox in the item.
