PyQT with ROS Melodic
I tried to do it with
www.notion.so
I tried to do it with
but I need to do some work fot this.
because there are some errors about QT4.
QT4 is depreciated,
and ROS Melodic support QT5 officially.
so I need to remove some packages for this job done in ROS Melodic environment.
so
1. Delete test_gui, qt4rosgui, vizlib_test package.
2. there are wrong phrase in CMakeLists.txt file in qt_ros_test package.
so change
catkin_package( INCLUDE_DIRS include # LIBRARIES client_plugin CATKIN_DEPENDS roscpp std_msgs # DEPENDS system_lib )
to
catkin_package( # INCLUDE_DIRS include # LIBRARIES client_plugin CATKIN_DEPENDS roscpp std_msgs # DEPENDS system_lib )
3. Install qtcreator
sudo apt-get install qtcreator
4. Install qt-5-default
sudo apt-get install qt5-default
5. add line to CMakeLists.txt from dyn_cfg_gui package.
change
include_directories( include ${CMAKE_CURRENT_BINARY_DIR}/.. ${catkin_LIBRARY_DIRS} )
to
include_directories( include ${CMAKE_CURRENT_BINARY_DIR}/.. ${catkin_LIBRARY_DIRS} ${catkin_INCLUDE_DIRS} )
6. change my_cplugin.cpp from rqt_mypkg like below
change
PLUGINLIB_DECLARE_CLASS(rqt_mypkg_cpp, MyPlugin, rqt_mypkg_cpp::MyPlugin, rqt_gui_cpp::Plugin)
to
PLUGINLIB_EXPORT_CLASS(rqt_mypkg_cpp::MyPlugin, rqt_gui_cpp::Plugin)

7. Add ui folder to CMAKE_AUTOUIC_SEARCH_PATHS
CMakeLists.txt from ros_cv_gui package.
change
set(CMAKE_INCLUDE_CURRENT_DIR ON) set(CMAKE_AUTOMOC ON) set(CMAKE_AUTOUIC ON) set(CMAKE_AUTORCC ON)
to
set(CMAKE_AUTOUIC_SEARCH_PATHS ui) set(CMAKE_INCLUDE_CURRENT_DIR ON) set(CMAKE_AUTOMOC ON) set(CMAKE_AUTOUIC ON) set(CMAKE_AUTORCC ON)

8. Edit CMakeList.txt from qt_ros_test package.
