CMFCRibbonButton constructor with HICON doesn‘t work properly because even though my icons are only 16x16
the button appear as 32x32.
使用HICON作为参数构建的RibbonButton即便指定用16X16的小图标，但最后显示在界面上仍是32X32的大图标。
class CSmallIconButton : public CMFCRibbonButton
{
public:
CSmallIconButton (UINT nID, LPCTSTR lpszText, HICON hIcon) :
CMFCRibbonButton(nID, lpszText, NULL, FALSE, hIcon)
{
}
virtual CSize GetImageSize (RibbonImageType type) const
{
if (type == RibbonImageLarge || m_hIconSmall == NULL)
{
return CSize(0, 0);
}
CSize sizeIcon(16, 16);
if (afxGlobalData.GetRibbonImageScale () != 1.)
{
sizeIcon.cx = (int) (.5 + afxGlobalData.GetRibbonImageScale () * sizeIcon.cx);
sizeIcon.cy = (int) (.5 + afxGlobalData.GetRibbonImageScale () * sizeIcon.cy);
}
return sizeIcon;
}
virtual void DrawImage (CDC* pDC, RibbonImageType type, CRect rectImage)
{
ASSERT_VALID (this);
ASSERT_VALID (pDC);
if (type != RibbonImageSmall || m_hIconSmall == NULL)
{
return;
}
CSize sizeIcon = GetImageSize(type);
::DrawIconEx (pDC->GetSafeHdc (), rectImage.left, rectImage.top, m_hIconSmall, sizeIcon.cx, sizeIcon.cy, 0, NULL, DI_NORMAL);
}
};后来发现，MainPannel上的CMFCRibbonMainPanelButton也是如此，使用类似的方法即可。CMFCRibbonButton使用HICON作为参数的构造函数BUG,布布扣,bubuko.com
