Title Bar is Pushed to the Right in QT Dock Widget

[A Former User]

Hello everyone, hope all is well! Currently, I am trying to host a QChart inside a dockWidget, and here is the code I am using (huge thanks to those who helped me out the other day) in my MainWindow file thus far:

[MainWindow.cpp]

QFrame *frame = new QFrame();


    QLineSeries *series = new QLineSeries();
    series->append(0, 6);
    series->append(2, 4);
    series->append(3, 8);
    series->append(7, 4);
    series->append(10, 5);
    *series << QPointF(11, 1) << QPointF(13, 3) << QPointF(17, 6) << QPointF(18, 3) << QPointF(20, 2);

    QChart *chart = new QChart();
    chart->legend()->hide();
    chart->addSeries(series);
    chart->setTitle("Line Chart Example");

    QChartView *chartView = new QChartView(chart);
    chartView->setRenderHint(QPainter::Antialiasing);
    chartView->setMinimumSize(600,600);
    chartView->setParent(frame);

    QComboBox *q = new QComboBox();
    q->setParent(frame);
    frame->setParent(ui->dockWidget);

However, I have run into a problem, as the title bar is pushed to the right. Here is a picture of what I am talking about:

I would like to have the chart (and combo box) under the title bar like one would expect. I would especially like the title box to be seen as one would normally expect; currently, the title bar window buttons (close, minimize/fullscreen buttons) are not even in the frame. What would I need to do to fix this issue?

You should add your widgets to a layout.

Don't assign parents manually. Use layouts instead. Also docks already have an internal layout so use their setWidget instead.

In short replace this:

QFrame *frame = new QFrame();

QChartView *chartView = new QChartView(chart);
chartView->setParent(frame);

QComboBox *q = new QComboBox();
q->setParent(frame);
frame->setParent(ui->dockWidget);

with:

QFrame *frame = new QFrame();
QChartView *chartView = new QChartView(chart);
QComboBox *q = new QComboBox();

QVBoxLayout* layout = new QVBoxLayout(frame);
layout->addWidget(q);
layout->addWidget(chartView);

ui->dockWidget->setWidget(frame);
