Problem
What are the steps to make the grid send notifications to its parent dialog? I have placed a grid in a dialog and would like the dialog to capture the grid's double-click event (and others as well).
Cause
Action
Here are some steps:
Define your own message in a header:
| // Custom Objective Grid Messages #define OG_LBUTTONCLK 01 |
Override corresponding Objective Grid method:
| protected: | ||
| virtual BOOL OnLButtonClickedRowCol(ROWCOL nRow, ROWCOL nCol, UINT nFlags, CPoint pt); | ||
In CPP send a message to the parent dialog:
| // Get a pointer to the parent dialog (works // also if grid is embedded in a record // info window) CDialog* GetParentDialog(CWnd* pWnd) { |
||
| return (CDialog*) GXGetParentWnd(this, RUNTIME_CLASS(CDialog), TRUE); | ||
| }
BOOL CGXObGrid::OnLButtonClickedRowCol(ROWCOL nRow, ROWCOL nCol, UINT nFlags, CPoint pt) |
||
| GetParentDialog(this)->SendMessage(WM_COMMAND, GetDlgCtrlID(), MAKELONG(m_hWnd, OG_LBUTTONCLK)); | ||
| #else | ||
| GetParentDialog(this)->SendMessage(WM_COMMAND, MAKELONG(GetDlgCtrlID(), OG_LBUTTONCLK), (LPARAM) m_hWnd ); | ||
| #endif | ||
| return TRUE; | ||
| } | ||
In dialog message map, something like this:
| ON_CONTROL(OG_LBUTTONDBLCLK, IDC_YOURGRID, OnOGLButtonDblClk) |
Do whatever you need to do in the function.
