qtabwidget

This is the same question as in: How to change text alignment in QTabWidget? I tried to port that python code into C++ but it doesn't seem to work. Here is header file: #include <QTabBar> class HorizontalTabWidget : public QTabBar { Q_OBJECT public: explicit HorizontalTabWidget(QWidget *parent = 0); protected: void paintEvent(QPaintEvent *); QSize sizeHint() const; }; Here is source file: void HorizontalTabWidget::paintEvent(QPaintEvent *) { for(int index = 0; index < count(); index++) { QPainter * painter = new QPainter(this); painter->begin(this); painter->setPen(Qt::blue); painter->setFont

I was wondering how to create (using PyQt4) a derived QTabWidget with a check box next to each tab title? Like this: Jib Actually I chose to only subclass QTabWidget. The checkBox is added at the creation of a new tab and saved to a list in order to get its index back. setCheckState/isChecked methods are intended to control the state of each checkBox specified by its tab index. Finally, the "stateChanged(int)" signal is captured and remitted with an extra parameter specifying the index of the checkBox concerned. class CheckableTabWidget(QtGui.QTabWidget): checkBoxList = [] def addTab(self,

How To Make Text Direction From Left To Right Instade Of Top To Bottom In this answer I will make a python translation of my another answer written in C++. from PyQt5 import QtCore, QtGui, QtWidgets class TabBar(QtWidgets.QTabBar): def tabSizeHint(self, index): s = QtWidgets.QTabBar.tabSizeHint(self, index) s.transpose() return s def paintEvent(self, event): painter = QtWidgets.QStylePainter(self) opt = QtWidgets.QStyleOptionTab() for i in range(self.count()): self.initStyleOption(opt, i) painter.drawControl(QtWidgets.QStyle.CE_TabBarTabShape, opt) painter.save() s = opt.rect.size() s

Many professional applications (such as web browsers) give the user the ability to detach tabs from a tab bar. Surprisingly, Qt4 does not provide this functionality. Some might say that this functionality is provided by using tabified QDockWidgets. However, it could also be argued that QDockWidgets implementation makes it look unprofessional and un-intuitive to users. I found a partially working C++ example in this post on the Qt Centre forum. It was incomplete and buggy. However, I was able to use it as reference and a starting point to create my own DetachableTabWidget using PyQt. Since I

I want to detect middle mouse clicks on a QTabWidget. I was expecting there to be a mouse event related signal on QWidget, but all I am seeing are methods. Do I need to subclass the QTabWidget and then override said methods in order to do what I want, or am I missing something? You can either install an event filter on the QTabBar (returned by QTabWidget.tabBar() ) to receive and handle press and release events, or subclass QTabBar to redefine mousePressEvent and mouseReleaseEvent and replace the QTabBar of the QTabWidget with QTabWidget.setTabBar() . Example using the event filter: class

Assuming I have a QTabWidget that contains 5 sub-tabs. Now I want to show/hide a sub-tab in one of 5 sub-tabs by following code ui->twListTabs->widget(0)->hide(); // Hide first sub-tab But this didn’t work for me. Do you have any solutions? Thanks! You only have the option to use: void QTabWidget::removeTab(int index) You need to store the pointer to the QWidget in the tab so that you can later insert it. You could e.g. do something like: class TabWidget : public QTabWidget { Q_OBJECT enum tabwidgets {tabwidget1,tabwidget2,...,number_of_tabwidgets}; QWidget* widgets_[number_of_tabwidgets];

I have a QTabWidget with too many tabs and they overflow with scroller arrows. I want to increase the width of the scroller arrows by more than twice of the default width so they are easier to use on a touchscreen. There is a QTabWidget StyleSheet example but I cannot seem to get it to work nicely. The stylesheet below produces this screenshot QTabBar::scroller { /* the width of the scroll buttons */ width: 40px; } QTabBar QToolButton { /* the scroll buttons are tool buttons */ width: 15px; border-width: 2px; } where I would like something like this screenshot I edited. Method #1: This appears
