fromWinHBITMAP is it avaialable in QT 5.1.1

问题

The documents state that the function isavailable however I get an error with the statement

img = QPixmap::fromWinHBITMAP(hRetVal).toImage();

The error is

error C3861: 'fromWinHBITMAP': identifier not found

I tried including

#include <QPixmap>

However I am still getting that . Any suggestions ?

回答1:

It was moved into the QtWin namespace.

#include <QtWin>

HBITMAP bitmap = ...
QtWin::HBitmapFormat format = ...

QPixmap pixmap = QtWin::fromHBITMAP(bitmap, format);
