Where is the style.qss in the OS? Is it possible to customize the gzclient menus at runtime?

edit

Hi all,

I'm trying to customize the gzclient menus.

I see the menus are added on MainWindow.cc

It seems they are customized at runtime by loading the :/style.qss file at runtime.

I tried to find that file in the osrf/ros:kinetic-desktop-full docker with find / -name style.qss but I couldn't find the file.

Does anybody know where that file is located? I didn't understand the : in the filename when loading with QFile file(":/style.qss");

PS: I saw a similar question, but there was no answer there, that is why I asked here.

EDIT 1: Thanks to @chapulina we have the custom_gazebo_style that should do the job.

However, to be able to Compile I had to modify the CMakeLists.txt to:

cmake_minimum_required(VERSION 2.8 FATAL_ERROR)
set(CMAKE_AUTOMOC ON)
set(CMAKE_CXX_FLAGS "-std=c++11")

find_package(Qt5Core REQUIRED)
find_package(Qt5X11Extras REQUIRED)
find_package(Qt5Widgets REQUIRED)
find_package(Qt5Gui REQUIRED)
find_package(gazebo REQUIRED)

QT5_ADD_RESOURCES(resources_RCC resources.qrc)

include_directories(SYSTEM ${GAZEBO_INCLUDE_DIRS})
link_directories(${GAZEBO_LIBRARY_DIRS})

add_library(custom_gazebo_style SHARED
  CustomGazeboStyle.cc
  ${resources_RCC}
)
target_link_libraries(custom_gazebo_style ${GAZEBO_LIBRARIES}
    ${Qt5Widgets_LIBRARIES}
    ${Qt5X11Extras_LIBRARIES}
    ${Qt5Gui_LIBRARIES}
    ${Qt5Core_LIBRARIES}
    ${Qt5Widgets_LIBRARIES})

I modified because of the 5 errors below:

1. /usr/include/c++/5/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

2. /usr/include/gazebo-7/gazebo/gui/qt.h:23:17: fatal error: QtGui: No such file or directory

3. /usr/include/gazebo-7/gazebo/gui/qt.h:24:20: fatal error: QX11Info: No such file or directory

4. /usr/include/gazebo-7/gazebo/gui/qt.h:24:20: fatal error: QX11Info: No such file or directory

5. /usr/include/gazebo-7/gazebo/gui/qt.h:25:19: fatal error: QWidget: No such file or directory

I'm probably missing something.

After the modifications on CMakeLists.txt everything compiled, but I couldn't load the plugin. If I call gazebo worlds/empty.world --gui-plugin $(pwd)/libcustom_gazebo_style.so --verbose the program finishes right away with code 255.

If I run gzserver instead of gazebo (using the same parameters) and then launch gzclient (also with the same parameters), gzclient crases with Segmentation fault (core dumped).

I checked there was no other gzclient running and GAZEBO_MASTER_URI=http://localhost:11345.

Well, maybe is the version 7.16.0 I'm using with Docker. I may try a different gazebo version to see whether the error goes away.

EDIT 2:

With gazebo 9.0.0, the custom_gazebo_style works like a charm.
