Qt工具栏和菜单栏

为什么不做这项工作？它应该是这样工作的：当单击“文件”时，工具栏（不是菜单栏）显示在菜单栏下方，菜单栏上有不同的按钮，可以在“文件”菜单中找到，当单击“编辑”时， “文件”工具栏被隐藏，并显示“编辑”工具栏。Qt工具栏和菜单栏

menubar = new MyMenuBar(this);//this is a menubar with "file" and "edit" 
menubar->setGeometry(0,0,1100,30); 

ftoolbar = new MyFileToolBar(this); // this is a toolbar with buttons that would be 
// found in a "file" menu 
ftoolbar->setGeometry(0,30,1100,40); 
ftoolbar->hide(); 

etoolbar = new MyEditToolBar(this); // this is a toolbar with buttons that would be 
//found in an "edit" menu 
etoolbar->setGeometry(0,30,1100,40); 
etoolbar->hide(); 

//here down does not work 
connect(menubar->File, SIGNAL(aboutToShow()), ftoolbar, SLOT(show())); 
connect(menubar->File, SIGNAL(aboutToHide()), ftoolbar, SLOT(hide())); 


connect(menubar->Edit, SIGNAL(aboutToShow()), etoolbar, SLOT(show())); 
connect(menubar->Edit, SIGNAL(aboutToHide()), etoolbar, SLOT(hide()));

没关系！我解决了它，但由于某种原因，stacko不让我回答我的问题......所以不要回答。我用aboutToShow（）替换触发（QAction *） –

我有兴趣看到菜单栏内的工具栏的屏幕截图。 – 2011-12-11 07:23:21

@Sosukodo：在菜单栏下方（正常位置）。不在里面。 – TonyK

我做了什么triggered(QAction*)意味着坏的假设。

我更换

connect(menubar->File, SIGNAL(triggered(QAction*)), ftoolbar, SLOT(show())); 
connect(menubar->File, SIGNAL(triggered(QAction*)), ftoolbar, SLOT(hide())); 


connect(menubar->Edit, SIGNAL(triggered(QAction*)), etoolbar, SLOT(show())); 
connect(menubar->Edit, SIGNAL(triggered(QAction*)), etoolbar, SLOT(hide()));

与

connect(menubar->File, SIGNAL(aboutToShow()), ftoolbar, SLOT(show())); 
connect(menubar->File, SIGNAL(aboutToHide()), ftoolbar, SLOT(hide())); 


connect(menubar->Edit, SIGNAL(aboutToShow()), etoolbar, SLOT(show())); 
connect(menubar->Edit, SIGNAL(aboutToHide()), etoolbar, SLOT(hide()));
