Re: DrawItem of HeaderCtrl 5-Sep-01 4:00 5-Sep-01 4:00  yes parent gets wm_drawitem with header ctrl id (fprocessed: false) t! Re: DrawItem of HeaderCtrl Tomasz Sowinski5-Sep-01 4:08 Tomasz Sowinski 5-Sep-01 4:08  Do you have ON_WM_DRAWITEM_REFLECT in CYourHeader's message map? Tomasz Sowinski -- http://www.shooltz.com Re: DrawItem of HeaderCtrl 5-Sep-01 4:08 5-Sep-01 4:08  sorry but _is_ virtual afxcmn.h class CHeaderCtrl : public CWnd virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct); t! Re: DrawItem of HeaderCtrl Tomasz Sowinski5-Sep-01 4:17 Tomasz Sowinski 5-Sep-01 4:17  sorry but _is_ virtual You're right, it is virtual. But it doesn't buy you anything. You still need ON_WM_DRAWITEM_REFLECT. Tomasz Sowinski -- http://www.shooltz.com Re: DrawItem of HeaderCtrl 5-Sep-01 4:13 5-Sep-01 4:13  wm_drawintem_reflect? where to find it? i tried wm_drawintem but is not called too t! Re: DrawItem of HeaderCtrl Tomasz Sowinski5-Sep-01 4:21 Tomasz Sowinski 5-Sep-01 4:21  No, there's no message named WM_DRAWITEM_REFLECT. You need a macro in the message map. BEGIN_MESSAGE_MAP(CYourHeader, CHeaderCtrl) //{{AFX_MSG_MAP(CYourHeader) // wizard stuff //}}AFX_MSG_MAP ON_WM_DRAWITEM_REFLECT() END_MESSAGE_MAP() This will connect your DrawItem method into MFC message handling mechanism. Parent window will call CYourHeader::DrawItem when handling WM_DRAWITEM. Tomasz Sowinski -- http://www.shooltz.com Re: DrawItem of HeaderCtrl 5-Sep-01 4:44 5-Sep-01 4:44  nothing i tried afx_msg void DrawItem ( LPDRAWITEMSTRUCT lpDrawItemStruct ); into hdr.h too - the same when i look to examples i have (tree-list-ctrls on cp) there is my version only, i see nothing like this t! Re: DrawItem of HeaderCtrl Tomasz Sowinski5-Sep-01 4:26 Tomasz Sowinski 5-Sep-01 4:26  Another idea: put the breakpoint in CHeaderCtrl::OnChildNotify. Does the program stop there? Tomasz Sowinski -- http://www.shooltz.com Re: DrawItem of HeaderCtrl 5-Sep-01 4:46 5-Sep-01 4:46  not stops there Re: DrawItem of HeaderCtrl Tomasz Sowinski5-Sep-01 4:58 Tomasz Sowinski 5-Sep-01 4:58  This is strange. I've checked the MFC sources. Here's how is expected to work: 1) parent window receives WM_DRAWITEM message - this is done by Windows itself, no MFC needed at this point 2) message map in CWnd class has a handler for this message. Default implementation is in CWnd::OnDrawItem 3) CWnd::OnDrawItem checks if message applies to menu or child window. If child window needs to be owner-drawn, it will be notified. Notification is performed by calling virtual CWnd::OnChildNotify. CHeaderCtrl and other classes override this function. 4) CHeaderCtrl::OnChildNotify explicitly checks for WM_DRAWITEM. If this is the case, it calls virtual CHeaderCtrl::DrawItem. Default implementation just contains ASSERT(FALSE), so you should at least have an assert (assuming some problems with overriding DrawItem). 5) overriden CYourHeader::DrawItem does the job. If CHeaderCtrl::OnChildNotify is not called, the next suspect is WM_DRAWITEM handler in parent class. Do you explicitly handle WM_DRAWITEM in the parent window? Tomasz Sowinski -- http://www.shooltz.com Re: DrawItem of HeaderCtrl 5-Sep-01 20:12 5-Sep-01 20:12  parent is commnon static control created into dialog editor (property page) no own class subclassed to it CStatic *pStatic = (CStatic*)((CPropertyPage*)wnd)->GetDlgItem(ID_STATIC); m_Header.Create(WS_CHILD | WS_VISIBLE | WS_DISABLED | HDS_HORZ, headerRect, pStatic, 12345 /* id */); t! Re: DrawItem of HeaderCtrl Tomasz Sowinski6-Sep-01 0:43 Tomasz Sowinski 6-Sep-01 0:43  OK - I can see what's going wrong. The parent isn't subclassed by MFC. When static window receives WM_DRAWITEM, the message goes to DefWindowProc, not to CWnd::OnDrawItem. The 'pStatic' pointer you're getting via GetDlgItem points to a temporary object, which is destroyed by MFC during idle processing. You need member CStatic variable associated - change the id from IDC_STATIC to something else, IDC_HDR_PARENT and use ClassWizard to add a member control variable. Optionally, add m_static manually to CYourDlg and call m_static.SubclassDlgItem(IDC_HDR_PARENT, this) in CYourDlg::OnInitDialog. Tomasz Sowinski -- http://www.shooltz.com Re: DrawItem of HeaderCtrl 6-Sep-01 21:27 6-Sep-01 21:27  really, parent was whole problem thanks very much t! A Simple Question 4-Sep-01 22:11 4-Sep-01 22:11  I been working with MFC for while and there is something I always wondered when I create controls dynamic for ex. CEdit *pEdit = new CEdit; pEdit->Create( WS_CHILD | WS_VISIBLE , rcEditRect , this , nID ); Then i always need to give the control an ID ( nID ) What is this for ?? Can I use any number here as long as it have not been used before ? what if 2 controllers get the same ID what could happened ? I never had any problems with it yet. I always use nID++ before creating the next controller. but it been bugging me that I didn't really understand the purpose of the nID I been suspecting that it is used when finding items when i use GetDlgItem .. But is that all it is used for ?? /Mathias Re: A Simple Question Christian Graus5-Sep-01 1:22 Christian Graus 5-Sep-01 1:22  The ID is defined in resource.h with lines like this: #define IDD_ACTION 1012 where IDD_ACTION is the name you gave your control when you created it in the dialog editor. When you create your own ID's it is imperative that no two controls on the one dialog have the same ID because a dialog recieves messages like WM_DRAWITEM, which specify the control that sent the message by specifying the ID.
