Re: Please help: trying to capture Enter Key in ComboBox within ToolBar
What kind of combobox is it? Simple/DorpDown/DropList? Is your
SubclassWindow call getting hit?

I have an SDI application with a toolbar (rebar) that contains a
combobox. I need to capture key events (particularly the enter key)
in that combobox. I have followed the MFCIE example from microsoft.
I have also read that in order to capture keypress events in the
combobox, you must dynamically subclass the edit control inside of the
combobox using the OnCtlColor event handler. I have done so like
this:
HBRUSH MyCombo::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor )
{
if (nCtlColor == CTLCOLOR_EDIT)
{
//Edit control
if (m_xEdit.GetSafeHwnd() == NULL)
m_xEdit.SubclassWindow(pWnd->GetSafeHwnd());
}
HBRUSH hbr = CComboBoxEx::OnCtlColor(pDC, pWnd, nCtlColor);
return hbr;
}
The call to SubclassWindow returns "1" which is supposed to be a
success. m_xEdit is my derived Edit Control (CComboEdit) which has
handlers for the key events:
BEGIN_MESSAGE_MAP(CComboEdit, CEdit)
//{{AFX_MSG_MAP(CComboEdit)
ON_WM_CHAR()
ON_WM_KEYDOWN()
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
void CComboEdit::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
TRACE("KEYDOWN");
}
void CComboEdit::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
TRACE("ONCHAR");
}
None of these keypress event handlers is ever hit. Am I missing
something with the dynamic subclassing? I have never done that
before, but it seemed pretty straightforward.
Please help, I've been stuck on this a while.
Thanks,
Jeff
