hallo!
habe in www.codeguru.com/listview/index.shtml etwas gefunden!
klappt jedoch noch nicht...
Original-Code:
"The header control in the ListView control sends notification to the parent window (e.i. the ListView) before it begins resizing a column. We can override the OnNotify() function in the CListCtrl derived class to handle this notification. The code below prevents resizing of all columns. Note that the resize cursor still shows up. "
BOOL CMyListCtrl::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
switch (((NMHDR*)lParam)->code)
{
case HDN_BEGINTRACKW:
case HDN_BEGINTRACKA:
*pResult = TRUE; // disable tracking
return TRUE; // Processed message
}
return CListCtrl::OnNotify(wParam, lParam, pResult);
}
mein Code:
Header:
...
virtual BOOL OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult) ;
...
Source:
...
BEGIN_MESSAGE_MAP(CMyClass, CDialog)
...
ON_NOTIFY( LVN_COLUMNCLICK, IDC_LSTCTRL, OnNotify )
...
END_MESSAGE_MAP()
BOOL CMyClass::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
switch (((NMHDR*)lParam)->code)
{
case HDN_BEGINTRACKW:
case HDN_BEGINTRACKA:
*pResult = TRUE; // disable tracking
return TRUE; // Processed message
}
return CMyClass::OnNotify(wParam, lParam, pResult);
}
irgendwie stimmt die Message ON_NOTIFY() noch nicht, wenn eine spalte in ihrer größe verändert wird/werden soll ...
eine idee? |
