Applying a background colour to a QCombox will result in fading.
Let us consider this code:
CMakeLists.txt
cmake_minimum_required(VERSION 3.5)
project(QCombobox LANGUAGES CXX)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
find_package(Qt6 COMPONENTS REQUIRED Core Widgets)
set(SOURCE_FILES
main.cpp
)
add_executable(QCombobox ${SOURCE_FILES})
target_link_libraries(QCombobox PRIVATE
Qt6::Core
Qt6::Widgets)
main.cpp
#include <QApplication> #include <QComboBox> int main(int argc,char*argv[]){ QApplication a(argc, argv); QComboBox b; b.addItem("a"); b.setStyleSheet("background: red;"); b.show(); return a.exec(); }
It renders as:
It not the same as the "real" red colour that I get when I click on the QComboBox:
Note: the colour is not faded if setFlat() is true
