Problem
Can I outline cells depending on their value?
Cause
Action
The following example changes only the SetInterior( ) style of a cell, which can be one of
- gray: value not used (cell will be made read-only, another change)
- white: value is not yet set
- green: value is set, interacting values result in feasible set
- red: value is set, interacting values result in infeasible set
All other properties of the cell remain unchanged.
| BOOL CSampleView::GetStyleRowCol(ROWCOL nRow, ROWCOL nCol, CGXStyle& style, GXModifyType mt, int nType) { |
||||
| CMyGridView::GetStyleRowCol(nRow, nCol, style, mt, nType); if (nRow > 0 && nCol > 0) { |
||||
| CString s = style.GetValueRef( ); if (criteria_1) { |
||||
| // disable the cell - user can't click into it anymore style.SetEnabled(FALSE).SetInterior(RGB(192,192,192)); |
||||
| } else if (s.IsEmpty( )) { |
||||
| // make white if empty style.SetInterior(RGB(255,255,255)); |
||||
| } else if (invalid s) { |
||||
| // make red if invalid syle.SezInterior(RGB(255,0,0)); |
||||
| } else { |
||||
| // make green if valid style.SetInterior(RGB(0,255,0)); |
||||
| } | ||||
| } return TRUE; |
||||
| } | ||||
This would also be a good example for using base styles. See "What is a base style"
