How get the resource root infomation

[wlzxzq]

After I have created a project and added resource information, I can't find resource root in the UI interface。

[Levi-Armstrong]

When you run the application is it visible?

[wlzxzq]

Yep，it can be visible. although i can not find the resource root, I can input the media's paths.

Yep，it can be visible. although i can not find the resource root, I can input the media's paths.是的，它是可见的。虽然我找不到资源根目录，但我可以输入媒体的路径。

请问你解决这个问题了吗？

Could you please use English so that others can take part in the conversation?

I believe that the directory of the ROS workspace differs from the typical QT project, which causes QT to be unable to locate the qrc files.

set(CMAKE_INCLUDE_CURRENT_DIR ON)
file(GLOB PRO_FORM_DIR RELATIVE ${CMAKE_CURRENT_SOURCE_DIR} ui/*.ui)
file(GLOB PRO_RESOURCES_DIR RELATIVE ${CMAKE_CURRENT_SOURCE_DIR} resource/*.qrc)
file(GLOB_RECURSE PRO_INCLUDE_DIR RELATIVE ${CMAKE_CURRENT_SOURCE_DIR} FOLLOW_SYMLINKS include/*.hpp *.h )
file(GLOB_RECURSE PRO_SOURCES_DIR RELATIVE ${CMAKE_CURRENT_SOURCE_DIR} FOLLOW_SYMLINKS src/*.cpp)
