Custom TabWidget button

[mero]

How can I create tab "+" like in firefox ?
plusff.png

I write something like this, but it looks different than in firefox

.cpp

TabManager::TabManager(QWidget *parent) : QTabWidget(parent)
{
    tab = tabBar();
...
    this->addTab(new QWidget(), QIcon("plus.png"), "");
...
}

TabManager::TabManager(QWidget *parent) : QTabWidget(parent)
{
    tab = tabBar();
...
    this->addTab(new QWidget(), QIcon("plus.png"), "");
...
}

.h

class TabManager : public QTabWidget
{
    Q_OBJECT
public:
    TabManager(QWidget *);
 
private:
    QTabBar *tab;

class TabManager : public QTabWidget
{
    Q_OBJECT
public:
    TabManager(QWidget *);

private:
    QTabBar *tab;

result is:

plus.png

so question is - do I need to change paint event for QTabWidget or QTabBar ?
or maybe there is another way to do that ?

If you want a direct equivalent then I'd add a tool button to the tab bar and reposition it as necessary.

So i will not make new thread my question is: How i can give QMenu and QTabBar to Window frame like in Firefox tab.png and how i can style frame i don't mean QFrame but Window frame for example GOM Player hasn't got windows's usualy frame but it has it's frame

I would start by creating a custom QWidget (derived from QTabBar) that contains both a QTabBar and a QToolBar widget in a layout. Then, derive a custom QTabWidget class that replaces its native QTabBar with an instance of your custom tab bar class (see QTabWidget::setTabBar()). This is a protected function, so you are forced to derive a new QTabWidget class. You would probably need to do that anyway, because you will be changing the tool bar contents depending on what is being displayed in a specific tab.

this isn't quite what i want because still stay window's frames. What you wrote is good but it will not look good i want tabbar in frame

I know how make QToolBar but i don't know how i can dock it to Top when i create toolbar in Widget

QToolbar *bar= new QToolbar("toolbar",this);

QToolbar *bar= new QToolbar("toolbar",this);

QToolbar *bar= new QToolbar("toolbar",this);

toolbar.png but i want dock it to top like toolbar2.png

// MainWindow.cpp constructor:
 
QToolBar *bar = new QToolBar( "toolbar", this );
QDockWidget * dock = new QDockWidget( "dockwidget", this );
dock->setAllowedAreas( Qt::TopDockWidgetArea );
dock->setFloating( false );
dock->setWidget( toolbar );

// MainWindow.cpp constructor:

QToolBar *bar = new QToolBar( "toolbar", this );
QDockWidget * dock = new QDockWidget( "dockwidget", this );
dock->setAllowedAreas( Qt::TopDockWidgetArea );
dock->setFloating( false );
dock->setWidget( toolbar );

It's don't work like i want. I have QWidget and i want add toolbar to the Widget and i want same toolbar like in QMainWindow do you understand what i mean ???

[wysota]

Then why don't you use QMainWindow instead of QWidget as your base class?

I found how to solve it

QVBoxLayout* vbox = new QVBoxLayout(this);
    vbox->addWidget(toolBar);
    vbox->setContentsMargins(0,0,0,0);
    vbox->setSpacing(0);
    setLayout(vbox);

QVBoxLayout* vbox = new QVBoxLayout(this);
    vbox->addWidget(toolBar);
    vbox->setContentsMargins(0,0,0,0);
    vbox->setSpacing(0);
    setLayout(vbox);

this is what i need
