Set focus to control in CPropertyPage

[martho]

Hello!

I have some CPropertyPages in a CPropertySheet (no wizard, just tabs). The CPropertyPages contain a lot of edit- and listbox-control.

What I want:
- At start, I want to set the focus to a special control, which should NOT be first in tab-order
- I want to save the control which has focus so that when the users gets back to the page, the focus is on the same control.

Both is just not working, the focus is always at the control with tab-stop 1 when initialising the page/jumpung to the page.

I tried:
::OnInitDialog()
- Setting the focus with SetFocus()/GotoDlgCtrl()
- returning FALSE
=> The focus is still at the first control.

::OnSetActive
- Setting the focus with SetFocus()/GotoDlgCtrl()
=> The focus is still at the first control.

::OnSetFocus
- Setting the focus with SetFocus()/GotoDlgCtrl()
=> The focus is still at the first control.

Any other ideas?

I encount the same problem, who can tell me why?

And are you doing the same thing in your app too ?

I've tried to use SetFocus() in OnInitialDialog() and OnSetActive(), neither works.

What kind of control are you trying to set focus on ?
Also, does the same happen with a sample App ?

OK, I search out an article in MSDN which discusses the problem:

How to Change Default Control Focus on CPropertyPage

The information in this article applies to:

The Microsoft Foundation Classes (MFC) included with: Microsoft Visual C++, 32-bit Edition, version 4.0


SUMMARY
When a CPropertyPage is activated, the first control in the page's tab order will get the focus by default. To change the default to a different control, derive a class from CPropertyPage, override OnSetActive(), and post a user message to a member function that will actually set the focus to the desired control.


MORE INFORMATION
CPropertySheet's member function OnSetActive() is called when a PSN_SETACTIVE message is sent to that page. Attempting to set the focus to a control while in this handler won't produce the expected results because after this notification is handled, the tab control will get the focus.

Therefore, you need to post a message to the property sheet's message queue with a user message in order to set the focus to the desired control once the page is active.



Sample Code

// this is the user-defined message
#define WM_SETPAGEFOCUS WM_APP+2

BEGIN_MESSAGE_MAP(CMyPage, CPropertyPage)
ON_MESSAGE(WM_SETPAGEFOCUS, OnSetPageFocus)

END_MESSAGE_MAP()
BOOL CMyPage::OnSetActive() {

BOOL fRet = CPropertyPage::OnSetActive();

PostMessage(WM_SETPAGEFOCUS, 0, 0L);

return fRet;

}
LONG CMyPage::OnSetPageFocus(UINT wParam, LONG lParam) {

// IDC_BUTTON2 is the button on this property page
// that you want to give the default focus.

CButton* pBtn = (CButton*)GetDlgItem(IDC_BUTTON2);
ASSERT(pBtn);
pBtn->SetFocus();
return 0;
}
