COleControl::OnFontChanged
Called by the framework when the stock Font property value has changed.
virtual void OnFontChanged( );
Remarks
The default implementation calls COleControl::InvalidateControl. If the control is subclassing a Windows control, the default implementation also sends a WM_SETFONT message to the control's window.
Override this function if you want notification after this property changes.
Example
void CMyAxCtrl::OnFontChanged()
{
// Always set it to the container's font
if (m_MyEdit.m_hWnd != NULL)
{
IFontDisp* pFontDisp = NULL;
IFont *pFont = NULL;
HRESULT hr;
// Get the container's FontDisp interface
pFontDisp = AmbientFont();
if (pFontDisp)
{
hr = pFontDisp->QueryInterface(IID_IFont, (LPVOID *) &pFont);
if (FAILED(hr))
{
pFontDisp->Release();
return;
}
}
HFONT hFont = NULL;
if (pFont)
{
pFont->get_hFont(&hFont);
m_MyEdit.SendMessage(WM_SETFONT, (WPARAM)hFont, 0L);
}
pFontDisp->Release();
}
// Invalidate the control
m_MyEdit.Invalidate();
m_MyEdit.UpdateWindow();
COleControl::OnFontChanged();
}
