Hi,

Is there any documentation on the 'grid' unit?

1)
If not, can anybody tell me what is the difference between the OnSelectCell and OnBeforeSelection event?

2)
What does all these grid states mean? Selected and Focused is obvious, but the others not.
TGridDrawState = set of (gdSelected, gdFocused, gdFixed, gdHot, gdPushed);

Regards,
- Graeme -

gdFixed -- when drawing on cells of fixed rows (e.g. title row) or fixed columns (e.g. indicator column).

no idea what gdHot and gdPushed means :(

Hello Graeme,

They seens to be:

gdSelected: The cell is selected (usually many cells can be selected, I'm not sure in Lazarus).

gdFocused: The one that have the cell focus (focus rect around). In example the cell that will be edited.

gdFixed: :)

gdHot: Seens to be the one under the mouse pointer.

gdPushed: Maybe a different kind of fixed to be draw with a push effect.

From my point of view, one cell can be at the same time, selected,

focused, hot and maybe pushed, but not fixed.
