问题描述
现在不建议使用QPixmap :: toWinHBITMAP()，我找不到从QPixmap(或QImage)获取HBITMAP的方法.
Now that QPixmap::toWinHBITMAP() has been deprecated, I can't find a way to get an HBITMAP from a QPixmap (or QImage).
谷歌搜索，我发现有一个名为qt_pixmapToWinHBITMAP()的函数似乎可以满足我的需要，但是我找不到在.pro文件中应该启用的模块(如果有的话)或应该包含的头文件它，或者其他的东西.
Googling, I found there's a function called qt_pixmapToWinHBITMAP() which seems would do what I need, but I can't find what module I should enable -if any- in my .pro file or what header I should include to use it, or perhaps something else.
我需要HBITMAP的原因是使用VFW创建视频.当然，我很乐意仅使用Qt就能做到这一点.有QtMultimedia模块，但据我所知它不会导出视频，所以我想我一直坚持直接使用Windows api.
The reason I need a HBITMAP is to create a video using VFW. Of course, I'd love to be able to do that using only Qt. There's the QtMultimedia module, but as far as I can tell it doesn't export video, so I guess I'm stuck with using the windows api directly.
任何帮助将不胜感激.
推荐答案
我找到了！
我需要的只是QtWinExtras
All I needed was QtWinExtras
http://qt.gitorious.org/qt/qtwinextras
我的代码现在看起来像这样:
My code now looks something like this:
#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <qt_windows.h>
#include <QtWinExtras/QWinFunctions>
...
QPixmap pix(QSize(w,h));
...
HBITMAP hbm = QWinExtras::toHBITMAP(pix);
...
::DeleteObject(hbm);
我不知道是否需要包含所有这些标头，但是它对我有用.
I don't know if I need to include all those headers, but it works for me.
