What does a StringGrid's OnSetEditText event do?

Question

I thought OnSetEditText was fired whenever text in a cell changed. After setting a breakpoint and experimenting, I know that's wrong :-) So, first, when is this event fired?

Second, if I would like to have the text inside a grid cell continuously autosized, which event should I be coding to make this happen (note: I am using TMS's string grid derivative which includes a method for autosizing rows; I just have to figure out when to call it)?

Answer 1

The OnSetEditText event is fired every time the user changes the contents of the in-place editor control, assuming, of course, the control is editable (goEditing in Options). This is confirmed by the documentation, the VCL source code, and black-box verification.
