@SGaist That's a fair question and to answer that it's because on the actual dock widget itself, in the production code, there are two widgets that get placed inside the dock widget itself. The topFrame contains the layout for the QTabWidget as you have pointed out. The code that is not present, botFrame contains another QGridLayout. These two then get placed inside the QGridLayout which is the layout of QGroupBox. Then to answer Why am I subclassing a layout to put widgets in it? I guess this is a personal decision and can be argued either way. For now, I will say that you are correct, that the Widget should manage the way the GridLayout adds widgets to them. However, I will argue that since QGridLayout is it's own class; the Widget does not "own" the widgets, rather, the layout owns the widgets since QWidget does not have a addWidgets function in it. Therefore, QGridLayout owns and is responsible for the Widgets that it owns. Hence the decision that the QWidget is the parent, which has a QGridLayout, which the QGridLayout as the Child, has the widgets that belong inside of it. This is a programming decision that I made with these arguments.

Usually, it's the bigger widget added that sets the overall size of the QTabWidget.

Thank You @SGaist and @AndyS. I am able to get QToolButton of QTabBar by applying Fusion style. I applied Fusion Style By: #include "mainwindow.h" #include <QTimer> #include <QtGlobal> #include <QFile> #include <QLocale> #include <QSplashScreen> #include <QGuiApplication> #include <qstylefactory.h> int main(int argc, char *argv[]) { QLocale::setDefault(QLocale::system()); QApplication a(argc, argv); a.setStyle(QStyleFactory::create("Fusion")); MainWindow w; w.showMaximized(); return a.exec(); }

@mrjj Thx for the hint setStyleSheet("QTabWidget::pane {border-bottom: 0px;}"); did the trick

separate QTableWidget into a QTableView and a QStandardItemModel add a QSortFilterProxyModel as the model of QTableView and set the QStandardItemModel as the QSortFilterProxyModel's sourceModel call QSortFilterProxyModel::setFilterWildcard or QSortFilterProxyModel::setFilterRegExp to perform the searching See Basic Sort/Filter Model Example

Thank you! I see you specified height and width manually. That works so far. I will use that.

@raven-worx Great, it works. Actually I did try setting QTabWidget setAutoFillBackground(True) previously, but it didn't work. Now I tried set VGroupBox setAutoFillBackground(True), then the color changed to light grey which is the exact default color I need. Thanks so much, raven-worx.

@raven-worx ah right, couldn't be easier. :) Maybe I'll come up with another solution for my issue like subclassing and repainting the tabbar. For now that'll do the trick. Cheers

super :) its easy to overlook stuff in own code :)

You'll need to change the context to the second GL widgets before using it. As each time you render or do anything with OpenGL setup/parameters that you have the right context selected first for each widget.

@Masonsu your QTextEdit is an implementation detail of your Chatlog widget. You should use e.g. a slot in Chatlog that will internally append the text to your QTextEdit. So if you change it for something else. You don't have to rewrite everything because of that.

Had a similar Issue. Was able to find a solution. Below is a generic PyQt5 example that solves the problem using right click. import sys from PyQt5.QtGui import * from PyQt5.QtWidgets import * from PyQt5.QtCore import * class Tabs(QTabWidget): def __init__(self, parent): super().__init__(parent) self.parent = parent self.setAcceptDrops(True) self.tabBar = self.tabBar() self.tabBar.setMouseTracking(True) self.indexTab = None self.setMovable(True) self.addTab(QWidget(self), 'Tab One') self.addTab(QWidget(self), 'Tab Two') def mouseMoveEvent(self, e): if e.buttons() != Qt.RightButton: return globalPos = self.mapToGlobal(e.pos()) tabBar = self.tabBar posInTab = tabBar.mapFromGlobal(globalPos) self.indexTab = tabBar.tabAt(e.pos()) tabRect = tabBar.tabRect(self.indexTab) pixmap = QPixmap(tabRect.size()) tabBar.render(pixmap,QPoint(),QRegion(tabRect)) mimeData = QMimeData() drag = QDrag(tabBar) drag.setMimeData(mimeData) drag.setPixmap(pixmap) cursor = QCursor(Qt.OpenHandCursor) drag.setHotSpot(e.pos() - posInTab) drag.setDragCursor(cursor.pixmap(),Qt.MoveAction) dropAction = drag.exec_(Qt.MoveAction) def dragEnterEvent(self, e): e.accept() if e.source().parentWidget() != self: return print(self.indexOf(self.widget(self.indexTab))) self.parent.TABINDEX = self.indexOf(self.widget(self.indexTab)) def dragLeaveEvent(self,e): e.accept() def dropEvent(self, e): print(self.parent.TABINDEX) if e.source().parentWidget() == self: return e.setDropAction(Qt.MoveAction) e.accept() counter = self.count() if counter == 0: self.addTab(e.source().parentWidget().widget(self.parent.TABINDEX),e.source().tabText(self.parent.TABINDEX)) else: self.insertTab(counter + 1 ,e.source().parentWidget().widget(self.parent.TABINDEX),e.source().tabText(self.parent.TABINDEX)) class Window(QWidget): def __init__(self): super().__init__() self.TABINDEX = 0 tabWidgetOne = Tabs(self) tabWidgetTwo = Tabs(self) layout = QHBoxLayout() self.moveWidget = None layout.addWidget(tabWidgetOne) layout.addWidget(tabWidgetTwo) self.setLayout(layout) if __name__ == '__main__': app = QApplication(sys.argv) window = Window() window.show() sys.exit(app.exec_())

@Paul-Colby Yes paaul, it doesn't work for me neither any other advise ? regards

QDockWidget and QMainWindow are tied. That doesn't prevent you to use another QMainWindow as a central widget for your QMainWindow even though that would be a bit strange. Note that if you only want to work with dock widgets nothing forbids you to not use any central widget.

@mrjj that is right :D

Hi, I want change icon of tab when one page is selected (arrow at right) and for the other arrow at bottom. I think it's the same way to do this. I tried : QToolBox > QAbstractButton{ background-image: url(:/icones/deleteRed); image: url(:/icones/deleteRed); } But nothing happend.

In that case why not add a spinner or busy indicator and show the widget directly ? It will at least remove the feeling that your application is stuck.

@Chris-Kawa Maybe you can ping @AndyS again so we can take a look on it. I had no time for it to think about an own patch.

@maximus Yes, I decided not to do it.

To be precise: click the gear, choose 'Edit' en put the string [Solved] in front of the title of your post

Resuelto. El problema era que cuando hace el primer remove los indices cambian, así que cuando elimino el indice 1 los indices pasan de ser 0,1,2 a ser 0,1. El segundo remove intenta eliminar el indice 2 pero este dejó de existir cuando hace el primer remove. Así que la solución es esta: Partes::Partes(QWidget *parent) : QDialog(parent), ui(new Ui::Partes) { ui->setupUi(this); ui->Pestanas->setCurrentIndex(0); ui->Pestanas->removeTab(1); ui->Pestanas->removeTab(1); } Or: Partes::Partes(QWidget *parent) : QDialog(parent), ui(new Ui::Partes) { ui->setupUi(this); ui->Pestanas->setCurrentIndex(0); ui->Pestanas->removeTab(2); ui->Pestanas->removeTab(1); } Como puedo marcar este post como resuelto?

The solution is an undocumented trick: QTabBar { background-color: transparent; qproperty-drawBase:0; } This lets you make the dark grey area (called the "tab bar base") as transparent. Or, alternatively, you can style it by changing the background-color value to a color.

Great ! Thanks for sharing your solution :)

@Streakflash Yeah I agree. But a lot of stuff is not really possible from Designer. Sadly.

Thanks mrjj and Chris Kawa for your valuable response. Actually I want to create my own customized scroll-button for tabBar with either end button( two buttons like << and >> including qt already provided scroll-buttons < and >) So that we can directly go to the fist or last tab. In Qt scroll-button for Qtabbar provides only step forward or backward functionality means we can scroll only one tab at a time. Suppose my QTabBar contains 100 tab and currently visible tabs are 55,56,and 57 and if we want to go on first then we have to click approx 49 times or stay in clicked state for few seconds. if you guys have any approach for doing this efficiently then please. It would be highly appreciated.

@Andy314139 yeah the xml file is annoying. awful design. Use shift+f4 to switch between edit and UI , works so much better.

Yes, both vertical and horizontal types.
