如何爲OpenCV和Qt設置鏈接以使用createButton？

我正在看opencv highgui示例（像connectedcomponents.cpp）並嘗試習慣添加GUI元素。目前，我想添加一個按鈕：如何爲OpenCV和Qt設置鏈接以使用createButton？

void on_button(int, void*){ 
    cout << "click" << end; 
} 
//in main() 
createButton("test",on_button);

但我得到一個鏈接錯誤：

g++ -c -pipe -g -gdwarf-2 -arch x86_64 -Xarch_x86_64 -mmacosx-version-min=10.5 -Wall -W -DQT_CORE_LIB -I../../../QtSDK/Desktop/Qt/474/gcc/mkspecs/macx-g++ -I. -I../../../QtSDK/Desktop/Qt/474/gcc/lib/QtCore.framework/Versions/4/Headers -I../../../QtSDK/Desktop/Qt/474/gcc/include/QtCore -I../../../QtSDK/Desktop/Qt/474/gcc/include -I/opt/local/include -I../../../QtSDK/Desktop/Qt/474/gcc/include -I. -F/Users/george/QtSDK/Desktop/Qt/474/gcc/lib -o main.o main.cpp

     _main in main.o 
make: Leaving directory `/Users/george/Documents/Qt/CVConnectedComponent' 
ld: symbol(s) not found

至於我能理解，我不反對鏈接的QtCore庫正常。我有這樣的：

mac: LIBS += -framework QtCore

這：

mac: LIBS += -F$$PWD/../../../QtSDK/Desktop/Qt/474/gcc/lib/ -framework QtCore 

INCLUDEPATH += $$PWD/../../../QtSDK/Desktop/Qt/474/gcc/include 
DEPENDPATH += $$PWD/../../../QtSDK/Desktop/Qt/474/gcc/include

在Qt工程的.pro文件，但沒有運氣。我在osx 10.6.8上使用OpenCV 2.4.1和Qt 4.7.4。

鏈接到Qt Creator中的QtCore以在OpenCV中使用createButton的正確方法是什麼？

'CV :: createButton'不是'Qt'框架的一部分。（即使是這樣，你也必須連接'QtCore'和'QtGui'）。你可能應該鏈接'highgui' – Lol4t0 2012-07-28 11:26:01

我不知道，我認爲highgui在幕後引用Qt。我已經鏈接到libopencv_highgui.dylib，但仍然沒有找到符號錯誤 – 2012-07-28 11:29:11

而我試過鏈接對QtCore和QtGui框架沒有運氣:( – 2012-07-28 14:47:58
