本文主要总结菜单栏类QMenu和工具栏类QToolBar的用法，具体的用法，将通过一个实例进行讲解。

1.1新建一个widget工程，不要勾选ui界面设计，然后分别在widget.h，widget.cpp，main.cpp分别添加如下代码。

widget.h

#ifndef WIDGET_H

#define WIDGET_H

#include

#include

#include

#include

#include

#include

#include

class Widget : public QWidget

{

Q_OBJECT

public:

Widget(QWidget *parent = 0);

void createView();

void addControls();

void craeteToolBar();

void craeteMenu();

private slots:

void On_ClickedMenuActionGroup(QAction *action);

void On_ClickedToolBarActionGroup(QAction *action);

private:

QVBoxLayout *mainLayout;

// QVBoxLayout *mainWidgetLayout;

// QWidget *mainWidget;

QPushButton *m_PushButton;

QMenu *m_Menu;

QToolBar *m_ToolBar;

QActionGroup *m_MenuActionGroup;

QActionGroup *m_ToolBarActionGroup;

QAction *m_ActionMenu1;

QAction *m_ActionMenu2;

QAction *m_ActionToolBar1;

QAction *m_ActionToolBar2;

};

#endif // WIDGET_H

widget.cpp

#include "widget.h"

#include

Widget::Widget(QWidget *parent)

: QWidget(parent)

{

createView();

}

void Widget::createView()

{

mainLayout = new QVBoxLayout;

this->setLayout(mainLayout);

addControls(); //添加按钮控件

craeteToolBar(); //创建工具栏

craeteMenu(); //创建按钮栏

mainLayout->setMargin(0);

mainLayout->setSpacing(0);

}

void Widget::addControls()

{

//添加控件

m_PushButton = new QPushButton("test");

mainLayout->addWidget(m_PushButton);

}

void Widget::craeteToolBar()

{

//创建工具栏

m_ToolBar = new QToolBar;

m_ToolBarActionGroup = new QActionGroup(this);

QList m_ToolBarList;

m_ActionToolBar1 = new QAction(QStringLiteral("ToolBar1"));

m_ActionToolBar2 = new QAction(QStringLiteral("ToolBar2"));

m_ActionToolBar1->setCheckable(true);

m_ActionToolBar2->setCheckable(true);

m_ToolBarList.append(m_ActionToolBar1);

m_ToolBarList.append(m_ActionToolBar2);

m_ToolBarActionGroup->addAction(m_ActionToolBar1);

m_ToolBarActionGroup->addAction(m_ActionToolBar2);

m_ToolBar->addActions(m_ToolBarList);

m_ToolBar->setStyleSheet("background-color:rgb(200,40,43);color:rgb(204,204,204)");

mainLayout->addWidget(m_ToolBar);

connect(m_ToolBarActionGroup,SIGNAL(triggered(QAction*)),this,SLOT(On_ClickedToolBarActionGroup(QAction *)));

}

void Widget::craeteMenu()

{

//创建菜单栏

m_Menu = new QMenu;

m_MenuActionGroup = new QActionGroup(this);

QList m_MenuList;

m_ActionMenu1 = new QAction(QStringLiteral("Menu1"));

m_ActionMenu2 = new QAction(QStringLiteral("Menu2"));

m_ActionMenu1->setCheckable(true);

m_ActionMenu2->setCheckable(true);

m_MenuList.append(m_ActionMenu1);

m_MenuList.append(m_ActionMenu2);

m_MenuActionGroup->addAction(m_ActionMenu1);

m_MenuActionGroup->addAction(m_ActionMenu2);

connect(m_MenuActionGroup,SIGNAL(triggered(QAction*)),this,SLOT(On_ClickedMenuActionGroup(QAction *)));

m_Menu->addActions(m_MenuList);

mainLayout->addWidget(m_Menu);

}

void Widget::On_ClickedMenuActionGroup(QAction *action)

{

if(action->text().compare(m_ActionMenu1->text())==0)

{

qDebug()<

text()==%1").arg(m_ActionMenu1->text());

}

else if (action->text().compare(m_ActionMenu2->text())==0)

{

qDebug()<

text()==%1").arg(m_ActionMenu2->text());

}

}

void Widget::On_ClickedToolBarActionGroup(QAction *action)

{

if(action->text().compare(m_ActionToolBar1->text())==0)

{

qDebug()<

text()==%1").arg(m_ActionToolBar1->text());

}

else if (action->text().compare(m_ActionToolBar2->text())==0)

{

qDebug()<

text()==%1").arg(m_ActionToolBar2->text());

}

}

main.cpp

#include "widget.h"

#include

int main(int argc, char *argv[])

{

QApplication a(argc, argv);

Widget w;

w.resize(960,640);

w.show();

return a.exec();

}

1.2程序构建运行后，结果如下图所示：

总结：

构建界面的工具栏，主要用到QToolBar类，先用函数QToolBar::addAction(QAtion*)或者QToolBar::addActions(QList)将对应的QAction工具挂载进来。然后将该QToolBar挂载到QWidget上(跟普通的QPushButton一样挂载)。
