Resize WindowContainer in Dockwidget

Nertunt

Hey,

I have a QDockWidget that contains a WindowContainer for a Q3DSurface. My problem is that if I change the size of the dockWidget during runtime, the size of the Q3DSurface stays constant.

main {
    ....
    QDockWidget *dock = new QDockWidget();
    someParent->addDockWidget(Qt::DockWidgetArea::RightDockWidgetArea, dock);
}

In the class DataVisualizer:

DataVisualizer::DataVisualizer(QWidget *parent) : QWidget(parent) {

	this->setContentsMargins(QMargins(0, 20, 0, 0));
	QtDataVisualization::Q3DSurface graph = new QtDataVisualization::Q3DSurface();
	QWidget *container = QWidget::createWindowContainer(graph);
	

	QSize screenSize = graph->screen()->size();
	container->setMinimumSize(QSize(screenSize.width()/4, screenSize.height() /2));
	container->setMaximumSize(screenSize);

	QVBoxLayout *hLayout = new QVBoxLayout(this);
	hLayout->addWidget(container, 0);

}

I hope you have enough information. Thank you for intrest.

Best regards

Hi,

What version of Qt are you using ?
On what platform ?

Can you provide a complete minimal example showing that behaviour ?

Hey,

I use QT 5.11. with Visual Studio 2017 and Windows 10. Below a minimal working example.

#include <QtWidgets/QApplication>
#include "DataVisualizerWidget.hpp"


int main(int argc, char *argv[]) {
	QApplication app(argc, argv);
	QMainWindow window;
	
	QDockWidget *dock = new QDockWidget();
	DataVisualizerWidget visualizer = new DataVisualizerWidget(dock);
	window.addDockWidget(Qt::DockWidgetArea::RightDockWidgetArea, dock);

	window.show();
	return app.exec();
}

The header file for DataVisualizationWidget:

#pragma once
#include <QtWidgets/QWidget>

class QResizeEvent;

class MicroVisualizerWidget : public QWidget {
	Q_OBJECT

public:
	DataVisualizerWidget(QWidget *parent);
};

The source file for DataVisualizationWidget:

#include "DataVisualizerWidget.hpp"

#include <QVBoxLayout>
#include <QtGui/QScreen>
#include <QtDataVisualization\q3dsurface.h>

DataVisualizerWidget::DataVisualizerWidget(QWidget *parent) : QWidget(parent) {
	
        //definining the widget
	 QtDataVisualization::Q3DSurface *graph = new QtDataVisualization::Q3DSurface();
	QWidget *container = QWidget::createWindowContainer(graph);
	QSize screenSize = graph->screen()->size();
	container->setMinimumSize(QSize(screenSize.width()/4, screenSize.height()/3));
	container->setMaximumSize(screenSize);
	QVBoxLayout *hLayout = new QVBoxLayout(this);
	hLayout->addWidget(container, 0);

        // Setting the values for graph
	QtDataVisualization::QSurfaceDataArray *data = new QtDataVisualization::QSurfaceDataArray;
	QtDataVisualization::QSurfaceDataRow *dataRow1 = new QtDataVisualization::QSurfaceDataRow;
	QtDataVisualization::QSurfaceDataRow *dataRow2 = new QtDataVisualization::QSurfaceDataRow;
	
	*dataRow1 << QVector3D(0.0f, 0.1f, 0.5f) << QVector3D(1.0f, 0.5f, 0.5f);
	*dataRow2 << QVector3D(0.0f, 1.8f, 1.0f) << QVector3D(1.0f, 1.2f, 1.0f);
	*data << dataRow1 << dataRow2;

	QtDataVisualization::QSurface3DSeries *series = new QtDataVisualization::QSurface3DSeries;
	series->dataProxy()->resetArray(data);
	graph->addSeries(series);
}

I hope this helps. Thank you.
