Integration of laout into gridlayout

[Chanchan]

Hi ! So here is my two problems :) I have a Marblemap, a videostream and a pushbutton on my windows.
I placed them in the gridlayout. However when I resize the window, only the video resize, my marblemap doesn't expand too. I dont have the problem when my program is launched without the camera linked (so I only have a blackscreeen instead of my video).

I would like to have my map resized in proportion with the videoplayer inside my window :)

Here is my main where I integrate all layouts :)

#include <QApplication>
#include <QWidget>
#include "mafenetre.h"
#include <marble/MarbleWidget.h>
#include <QGridLayout>
#include <QFont>
#include <QSplitter>
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
   
    // On crée le widget Marble via openstreet map
    Marble::MarbleWidget *mapWidget = new Marble::MarbleWidget;
    mapWidget->setProjection(Marble::Mercator);
    mapWidget->setMapThemeId("earth/openstreetmap/openstreetmap.dgml");
    mapWidget->setWindowTitle("Test!");
    QWidget fenprincip;
    //fenprincip.setFixedSize(1600,900);
    MaFenetre *video= new MaFenetre;//(&fenprincip); le =New MaFenetre est là pour déclarer video en tant que widget pour le layout
    // Création du Layout Grid :
    QGridLayout *layout = new QGridLayout;
    QPushButton *switch_bouton = new QPushButton("Switch");
    switch_bouton->setFont(QFont("Comic Sans MS", 14));
    // Création des boites layout
    /*QVBoxLayout *videolayout = new QVBoxLayout;
    QHBoxLayout *maplayout = new QHBoxLayout;
    QVBoxLayout *switchLayout = new QVBoxLayout;*/
    /*//On met les Widget dedans
    videolayout->addWidget(video);//(x,y,hauteur,largeur)
    maplayout->addWidget(mapWidget);
    switchLayout->addWidget(m_bouton);
    mapWidget->sizePolicy();
    //Le redimensionnement auto ne marche pas sans trop de raison on va tenter avec une simple grille*/
   //On ajoute les widget à la grille
    layout->addWidget(video, 0,0,16,9);
    layout->addWidget(mapWidget,15,17,4,4);
    layout->addWidget(switch_bouton,14,17,1,4);
    // Connexion du clic du bouton à la fermeture de l'application
    QObject::connect(switch_bouton, SIGNAL(clicked()), video, SLOT(quit()));
   
    fenprincip.show();
    return app.exec();
}

Also my cpp file :

#include "mafenetre.h"
#include <QGraphicsScene>
#include <QGraphicsView>
#include <QGraphicsVideoItem>
#include <QDebug>
MaFenetre::MaFenetre(QWidget *parent) :
    QWidget(parent)
{
    //QString fichier = QCoreApplication::applicationDirPath() + QString("/test.mpg");
    qDebug() << QUrl("rtsp://ednded:sokzd@169.254.xxx.xx/axis-media/media.amp");
    player = new QMediaPlayer;
    player->setMedia(QUrl("rtsp://ednded:sokzd@169.254.xxx.xx/axis-media/media.amp"));
    // GUI 1
    QVBoxLayout *layoutPrincipal = new QVBoxLayout;
    videoWidget = new QVideoWidget(this);
    layoutPrincipal->addWidget(videoWidget);
    player->setVideoOutput(videoWidget);
    setLayout(layoutPrincipal);
    setWindowTitle(QString::fromUtf8("player"));
    //setFixedWidth(960);
    //setFixedHeight(540);
    connect(player, SIGNAL(stateChanged(QMediaPlayer::State)), this, SLOT(stateChanged(QMediaPlayer::State)));
    connect(player, SIGNAL(metaDataChanged()), this, SLOT(metaDataChanged()));
    connect(player, SIGNAL(metaDataChanged(const QString &, const QVariant &)), this, SLOT(metaDataChanged(const QString &, const QVariant &)));
    connect(player, SIGNAL(error(QMediaPlayer::Error)), this, SLOT(error(QMediaPlayer::Error)));
    player->play();
}
MaFenetre::~MaFenetre()
{
}
void MaFenetre::stateChanged(QMediaPlayer::State state)
{
    qDebug() << Q_FUNC_INFO << state;
    if (state == QMediaPlayer::StoppedState)
    {
        videoWidget->update();
    }
}
void MaFenetre::metaDataChanged()
{
    qDebug() << player->availableMetaData();
    if (player->isMetaDataAvailable())
    {
        qDebug() << player->metaData(QMediaMetaData::Title).toString();
        qDebug() << player->metaData(QMediaMetaData::Size);
        qDebug() << player->metaData(QMediaMetaData::Duration);
        qDebug() << player->metaData(QMediaMetaData::Resolution);
    }
}
void MaFenetre::metaDataChanged(const QString &key, const QVariant &value)
{
    //"AudioBitRate", "AudioCodec", "PixelAspectRatio", "Resolution", "VideoCodec"
    if(key == "AudioCodec")
        qDebug() << key << value;
    if(key == "VideoCodec")
        qDebug() << key << value;
    if(key == "Resolution")
        qDebug() << key << value;
}
void MaFenetre::error(QMediaPlayer::Error error)
{
    qDebug() << Q_FUNC_INFO << player->errorString() << error;
}

Thanks for helping me :)

Hi,

From the looks of it, you are trying to set your grid layout on your MaFenetre object which already has a layout which should give you an error message.

@SGaist Thanks for your answer :)

Oh sorry I forgot to delete the part (&fenprincip) (I modified my code but the problem is still here) :/

So I solved my problem by fixing all my coloumns with a setColumnSize :) Now everythings has the good place !
