dornhege,thanks very much!! Your reply lets me know about how to incorporate ROS and Qt, and the errors on my first post disappear, but it exists special errors:
error: expected ‘:’ before ‘slots’;;
error: ‘slots’ does not name a type
error: ‘signals’ does not name a type
However, in the definition of this class, I do have declare the " Q_OBJECT " And the head file is: #include <qlabel> #include <qstring>
#ifndef HELLOWIDGET_H_
#define HELLOWIDGET_H_
class HelloWidget : public QLabel {
Q_OBJECT
public:
HelloWidget(QWidget * parent = 0);
~HelloWidget();
public slots:
void showNewLetter();
protected:
QString _msg;
unsigned short _pos;
signals:
woid showNewLetter1(); //just for test
};
#endif /* HELLOWIDGET_H_ */
According to the answer, my new CMakeList.txt is:
cmake_minimum_required(VERSION 2.4.6)
include($ENV{ROS_ROOT}/core/rosbuild/rosbuild.cmake)
rosbuild_init()
find_package(Qt4 REQUIRED)
# enable/disable some Qt features
set( QT_USE_QTGUI TRUE )
set( QT_USE_QTOPENGL TRUE )
set( QT_USE_QTXML TRUE )
include(${QT_USE_FILE})
ADD_DEFINITIONS(-DQT_NO_KEYWORDS)
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
#set the default path for built libraries to the "lib" directory
set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)
set(qt_srcs
HelloWidget.cpp
MainWindow.cpp
)
set(qt_hdrs
HelloWidget.h
MainWindow.h
)
qt4_automoc(${qt_srcs})
QT4_WRAP_CPP(qt_moc_srcs ${qt_hdrs})
QT4_WRAP_UI(uis_h HelloWidget.ui)
# include this for ui_h
include_directories(${CMAKE_CURRENT_BINARY_DIR})
#uncomment if you have defined messages
rosbuild_genmsg()
rosbuild_add_executable(turtle_teleop_joy teleop_turtle_joy.cpp
${uis_h} ${qt_srcs} ${qt_moc_srcs})
target_link_libraries(turtle_teleop_joy ${QT_LIBRARIES})
Why I has this strange errors on my compiler, is because I lack of some Qt features, but I do not find any other features on web, or anywhere setting on my CMakeList.txt or the configuration of my Qt creator? Can anyone give me a hint? Thanks all the same!
