1.创建一个Qt gui application工程,使用设计器调出一个tabwidget控件,如下图
2.pro文件如下
QT += opengl # LIBS+=-IGLU LIBS += -lglut -lGLU TARGET = . TEMPLATE = app SOURCES += main.cpp mainwindow.cpp nehewidget.cpp HEADERS += mainwindow.h nehewidget.h FORMS += mainwindow.ui
4.输入$make ,产生ui_ mainwindow.h文件,然后修改ui_ mainwindow.h文件如下(红色为修改的地方)
/******************************************************************************** ** Form generated from reading UI file 'mainwindow.ui' ** ** Created by: Qt User Interface Compiler version 4.8.6 ** ** WARNING!

屏蔽掉如下语句
#compiler_uic_make_all: _mainwindow.h文件ui_mainwindow.h
#compiler_uic_clean:
# -$(DEL_FILE) ui_mainwindow.h
#ui_mainwindow.h: mainwindow.ui
# /usr/lib/i386-linux-gnu/qt4/bin/uic mainwindow.ui -o ui_mainwindow.h
还有修改语句
compiler_clean: compiler_moc_header_clean compiler_uic_clean为
compiler_clean: compiler_moc_header_clean
6,经过以上处理,重新$make一下,生成opengltest可执行文件
输入$./opengltest后如下
opengl设计的UI已经嵌入到了tabwidget空间中去了
附上程序的相关代码如下:
opengltest.pro
