Add an assert to this function checking that the index is valid before using it with wxGridOperations::GetLineStartPos(), and actually avoid calling the function when this is not the case to avoid assertion failures when wxEVT_GRID_CELL_LEFT_CLICK is handled in user code. Also add comments clarifying the preconditions for calling various drag-related functions. Closes #19218. |
