How to reduce space between two different columns in Qt?

[patelvrajn]

Shown below is the code and an image of the GUI I am currently working on. As you will notice, there is an abundant amount of space between the two columns in the App_Grid (The green box which is not part of the GUI, represents the space I am talking about). I have tried my best to reduce this space to as little as possible but I cannot seem to reduce it any further. Can someone please help me reduce this space further by enlarging the text edit on the right of the buttons column? On a side note, I don't understand the concept of the stretch property, would someone be able to explain that as well. Thank you in advance for any help.

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    int win_dim_h = 520;
    int win_dim_w = 945;
    this->setMinimumSize(win_dim_w,win_dim_h);
    this->setMaximumSize(win_dim_w,win_dim_h);

    QGridLayout *App_Grid = new QGridLayout();

    QPushButton *Test_Button = new QPushButton("Test");
    QPushButton *Test_Button2 = new QPushButton("Test2");

    QPushButton *Test_Button4 = new QPushButton("Test4");
    QTextEdit *Test_TextEdit = new QTextEdit();

    Test_Button->setMinimumHeight(25);
    Test_Button->setStyleSheet("background-color: white;");
    Test_Button2->setMinimumHeight(25);

    float widget_screen_prop = 7/8;

    App_Grid->setSpacing(100);
    App_Grid->addLayout(Tabs_Grid,0,0,0);
    App_Grid->addWidget(Test_TextEdit,0,1,0);
    App_Grid->setColumnMinimumWidth(1,(widget_screen_prop)*this->width());

    Menu_Grid-> addLayout(App_Grid, 1, 0, 1,2, Qt::AlignCenter);
    Menu_Grid-> addWidget(Logo, 0, 0, 0);
    Menu_Grid-> addWidget(Menu, 0, 1, 0);
    Logo->setMinimumWidth(7*this->width()/8);

    QWidget *central = new QWidget(this);
    setCentralWidget(central);
    central->setLayout(Menu_Grid);
    central->setStyleSheet("background-color: white;");
}

MainWindow::~MainWindow()
{
    delete ui;
}

@patelvrajn said in How to reduce space between two different columns in Qt?:

App_Grid->setSpacing(100);

Did you try smaller spacing?
