QMenu的个性化定制

经常使用菜单，菜单的定制相当重要，普通的样式设置不难，一般需求足以实现（QMenu + QAction）。如果要足够个性，则需要进行一定的定制。

说起定制，其实也是利用Qt中现成的组件进行组装而已，使用QMenu + QWidgetAction + QAction ，再加上QSS美化就可实现个性的QMenu。

先看效果（模仿酷狗所做的一个托盘菜单）：

![Center][] ![Center 1][]

主要代码如下：

SystemTray::SystemTray()

: QSystemTrayIcon()

this->createActions();

this->createPlayAction();

this->addActions();

this->translateLanguage();

this->setContextMenu(pop\_menu);

SystemTray::~SystemTray()

void SystemTray::translateLanguage()

this->setToolTip(tr("hey music"));

this->switchPlayToolTip(is\_paly);

backward\_button->setToolTip(tr("backward"));

forward\_button->setToolTip(tr("forward"));

show\_action->setText(tr("show"));

setting\_action->setText(tr("setting"));

lock\_lrc\_action->setText(tr("lock lrc"));

this->showLrc(is\_show);

logout\_action->setText(tr("logout"));

void SystemTray::createActions()

this->setIcon(QIcon(":/images/music.png"));

pop\_menu = new QMenu();

show\_action = new QAction(pop\_menu);

setting\_action = new QAction(pop\_menu);

lock\_lrc\_action = new QAction(pop\_menu);

show\_lrc\_action = new QAction(pop\_menu);

logout\_action = new QAction(pop\_menu);

connect(show\_action, &QAction::triggered, this, &SystemTray::showWidget);

connect(show\_lrc\_action, &QAction::triggered, this, static\_cast(&SystemTray::showLrc));

connect(login\_action, &QAction::triggered, this, &SystemTray::showLoginWidget);

connect(logout\_action, &QAction::triggered, this, &SystemTray::logoutWidget);

void SystemTray::createPlayAction()

play\_widget = new QWidget();

play\_widget\_action = new QWidgetAction(pop\_menu);

play\_button = new QPushButton();

backward\_button = new QPushButton();

forward\_button = new QPushButton();

music\_name\_label = new QLabel();

music\_name\_label->setFixedWidth(MUSIC\_NAME\_WIDTH);

music\_name\_label->setAlignment(Qt::AlignCenter);

QPixmap play\_pixmap(":/action/pause");

play\_button->setIcon(play\_pixmap);

play\_button->setIconSize(play\_pixmap.size());

play\_button->setObjectName("transparentButton");

QPixmap backward\_pixmap(":/action/backward");

backward\_button->setIcon(backward\_pixmap);

backward\_button->setIconSize(backward\_pixmap.size());

backward\_button->setObjectName("transparentButton");

QPixmap forward\_pixmap(":/action/forward");

forward\_button->setIcon(forward\_pixmap);

forward\_button->setIconSize(forward\_pixmap.size());

forward\_button->setObjectName("transparentButton");

backward\_button->setCursor(Qt::PointingHandCursor);

play\_button->setCursor(Qt::PointingHandCursor);

forward\_button->setCursor(Qt::PointingHandCursor);

QHBoxLayout \*layout = new QHBoxLayout();

layout->addWidget(backward\_button);

layout->addWidget(play\_button);

layout->addWidget(forward\_button);

layout->setSpacing(0);

layout->setContentsMargins(20, 0, 20, 0);

QVBoxLayout \*layout2 = new QVBoxLayout();

layout2->addLayout(layout);

layout2->addWidget(music\_name\_label, 0, Qt::AlignCenter);

layout2->setSpacing(5);

layout2->setContentsMargins(0, 0, 0, 5);

music\_name\_label->setText("player");

music\_name\_label->setEnabled(false);

play\_widget->setLayout(layout2);

play\_widget\_action->setDefaultWidget(play\_widget);

connect(play\_button, &QPushButton::clicked, this, &SystemTray::play);

connect(backward\_button, &QPushButton::clicked, this, &SystemTray::skipBackward);

connect(forward\_button, &QPushButton::clicked, this, &SystemTray::skipForward);

void SystemTray::addActions()

pop\_menu->addAction(play\_widget\_action);

pop\_menu->addSeparator();

pop\_menu->addAction(show\_action);

pop\_menu->addSeparator();

pop\_menu->addAction(setting\_action);

pop\_menu->addAction(lock\_lrc\_action);

pop\_menu->addAction(show\_lrc\_action);

pop\_menu->addSeparator();

pop\_menu->addAction(login\_action);

pop\_menu->addAction(logout\_action);
