Qt官方自带的QColorDialog类提供了一个指定颜色的对话框部件。#include

C++使用方法：

1.pro文件
LIBS += -L$${DESTDIR} #lib path
LIBS += "QtColorWidgets-Qt52.lib"
INCLUDEPATH += ../color_widgets/include/
INCLUDEPATH += ../color_widgets/include/QtColorWidgets/

2.cpp源文件
#include "color_dialog.hpp"
void Designer::on_actionColor_triggered()
{
    color_widgets::ColorDialog dlg;
    connect(&dlg, &color_widgets::ColorDialog::colorSelected, this, &Designer::color_changed);
    dlg.exec();
}

void Designer::color_changed(QColor color)
{
    int r, g, b, a;
    color.getRgb(&r, &g, &b, &a);
    color.getHsv(&r, &g, &b, &a);
}
