Problem
How can I transfer data between the grid and the document when I am using other views (e.g. a hierarchy chart) and need to update all views when a cell value has changed?

You should override StoreStyleRowCol( ) and store the style's value in your document.
| BOOL
CSampleView::StoreStyleRowCol(ROWCOL nRow, ROWCOL nCol,
const CGXStyle* pStyle, GXModifyType mt, int nType) { |
|||
| if (mt == gxRemove) // not supported | |||
| return FALSE; | |||
| // Note: Do not distinguish between
gxApplyNew, // gxCopy and gxOverride if (nRow > 0 && nCol > 0 && nType == 0) { |
|||
| GetDocument( )->StoreCellValue(nRow, nCol, style.GetValueRef( )); | |||
| } return CMyGridView::StoreStyleRowCol(nRow, nCol, pStyle, mt, nType); |
|||
| } | |||
You should override GetStyleRowCol( ) to retrieve the style's value from you doc:
| BOOL
CSampleView::GetStyleRowCol(ROWCOL nRow, ROWCOL nCol,
CGXStyle& style, GXModifyType mt, int nType) { |
|||
| BOOL b =
CMyGridView::GetStyleRowCol(nRow, nCol, style, mt,
nType); //
Note: Do not distinct between gxApplyNew, |
|||
| style.SetValue(GetDocument( )->GetCellValue(nRow, nCol); | |||
| } return b; |
|||
| } | |||
In your other view's OnUpdate( ) method, you should update the view when you get a CGXGridHint object, with hint-ID gxHintUpdateStyleRange:
| void CMyOtherView::OnUpdate(CView*
pSender, LPARAM lHint, CObject* pHint) { |
||||
| if (pHint != NULL &&
pHint->IsKindOf(RUNTIME_CLASS(CGXGridHint))) { |
||||
| CGXGridHint &info =
*((CGXGridHint*) pHint); switch (info.nId) |
||||
| Invalidate( ); break; |
||||
| } | ||||
| } | ||||
| } | ||||
