Horizontal text in QTabWidget

[mrjj]

Hi
You can use a QProxyStyle.
http://doc.qt.io/qt-5/qproxystyle.html
First time is a bit WTF so here an example.

class CustomTabStyle : public QProxyStyle {
public:
  QSize sizeFromContents(ContentsType type, const QStyleOption* option,
                         const QSize& size, const QWidget* widget) const {
    QSize s = QProxyStyle::sizeFromContents(type, option, size, widget);
    if (type == QStyle::CT_TabBarTab) {
      s.transpose();
    }
    return s;
  }

  void drawControl(ControlElement element, const QStyleOption* option, QPainter* painter, const QWidget* widget) const {
    if (element == CE_TabBarTabLabel) {
      if (const QStyleOptionTab* tab = qstyleoption_cast<const QStyleOptionTab*>(option)) {
        QStyleOptionTab opt(*tab);
        opt.shape = QTabBar::RoundedNorth;
        QProxyStyle::drawControl(element, &opt, painter, widget);
        return;
      }
    }
    QProxyStyle::drawControl(element, option, painter, widget);
  }
};

and set it
ui->tabWidget->tabBar()->setStyle(new CustomTabStyle);

@mrjj
hii i'm here again xD
me too i got the same probleme !! but where to put the code that you shared ?

[mrjj]

@Amine-Djeddi
Hi
just put in a .h file and include that where you need to use it
like create new file and call it TabProxy.h
past code to it. You will need to add include for QProxyStyle
and you are ready.

Then where you use it, #include " TabProxy.h"
and set on the one you want
ui->tabWidget->tabBar()->setStyle(new CustomTabStyle);

@Amine-Djeddi

Hi,

i've managed to implement this but the close button does not align with the new style. What do I do?

We don't know because you do not show any code...

I am trying to put the tab text in horizontal. I put the tabs in west orientation but the text appears in vertical like this picture:

en python : class HorizontalTabStyle(QProxyStyle):
def drawControl(self, element, option, painter, widget=None):
if element == QProxyStyle.CE_TabBarTab:
opt_tab = QStyleOptionTab(option)
# نجعل Qt يرسم النص كما لو كان في الأعلى (North) وبالتالي يكون أفقي
opt_tab.shape = QTabBar.RoundedNorth
super(HorizontalTabStyle, self).drawControl(element, opt_tab, painter, widget)
else:
super(HorizontalTabStyle, self).drawControl(element, option, painter, widget)
.....
self.tabWidgetResult.setTabPosition(QTabWidget.TabPosition.West)

    # نطبّق الستايل المخصص على الـ tabBar
    self.custom_style = HorizontalTabStyle(self.tabWidgetResult.style())
    self.tabWidgetResult.tabBar().setStyle( self.custom_style)

[jsulm]

@AZEDINE There is no picture. And please format your code properly.

[AZEDINE]

@jsulm

self.tabWidgetResult = self.findChild(QTabWidget, "tabWidgetResult")
       if self.tabWidgetResult:
           self.tabWidgetResult.tabBar().setCursor(Qt.CursorShape.PointingHandCursor)


       self.tabWidgetResult.setStyleSheet("
           QTabBar::tab {
               width: 29px;
               max-width: 100px;
               min-width: 20px;
           }

           QTabBar::tab:selected {
               background: #0E94A0;
               color: white; 
           }

           QTabBar::tab {
               color: #000000; 
           }

           QTabBar::tab::!selected {
               color: #0E94A0; 
           }

           QTabBar::tab {
               font-size: 14px;
               font-weight: bold; 
               margin: 5px; 
               padding: 5px; 
               border: 2px solid #0E94A0;
               border-radius: 10px; 
           }

           QTabBar::tab > QLabel {
               qproperty-alignment: AlignCenter; 
           transform: translate(0,10px) rotate(-90deg);
                   
           }

           QTabBar::tab:selected > QLabel {
               qproperty-alignment: AlignCenter; 
               transform: translate(0,10px) rotate(-90deg);
               
           }

       ")

@AZEDINE said in Horizontal text in QTabWidget:

I put the tabs in west orientation

According to the picture you don't: the tabs are arranged vertically. How did you set up the QTabWidget?

[AZEDINE]

@AZEDINE I am trying to put the tab text in horizontal. I put the tabs in west orientation but the text appears in vertical like this picture:

 self.tabWidgetResult.setTabPosition(QTabWidget.West)

[AZEDINE]

[jsulm]

@AZEDINE Did you try what @mrjj suggested in this thread?
