Question

I have following layouts: when I stretch the window, the size becomes like this: Is there a way to set the widgets in qgridlayout with the same size when the qgridlayout size changes ? Thanks. UPDATE The widget in qgridlayout: ``` #ifndef CVIMAGEWIDGET_H #define CVIMAGEWIDGET_H #include #include #include #include #include #include class CVImageWidget : public QGraphicsView { Q_OBJECT public: explicit CVImageWidget(QMainWindow *GUIWindow, QWidget *parent = 0); void drawBoarder(bool flag); void showImage(const QImage& image); void SetCameraID(int camID); int GetCameraID(); void closeDisplay(); ~CVImageWidget(); private: QGraphicsScene *scene_; int camera_id_; public slots: void resizeEvent(QResizeEvent *event); }; #endif // CVIMAGEWIDGET_H ``` CPP file ``` #include "cvimagewidget.h" #include #include CVImageWidget::CVImageWidget(QMainWindow *GUIWindow, QWidget *parent) : QGraphicsView(p…

When you add the items in layout, make sure you add stretch factor for all the rows and columns.

```
   int main(int argc, char *argv[])
    {
        QApplication a(argc, argv);

QWidget widget;
        QGridLayout layout;
        for( int i =0 ; i < 4; i++ )
        {
            layout.setRowStretch( i, 1);
            for ( int j = 0; j < 4; j++)
            {
                if( i == 0 )
                {
                    layout.setColumnStretch( j, 1 );
                }
                CVImageWidget * temp = new CVImageWidget( &widget );
                layout.addWidget( temp, i, j, 1, 1 );
                if( i ==0 && j== 0 )
                {
                    temp->showImage( QImage("/Users/sacp/Desktop/check.png") );
                }
            }
        }
        widget.setLayout( &layout );
        widget.show();
        a.exec();
        return 0;
    }
```

This is how it looks after resize
