Hi,
use setContentsMargin(0,0,0,0); method for both main layout and label.

Hi @Arqam

Try to change this line<layoutdefault spacing="6" margin="11"/>

@m.sue said in QLabel not starting from 0,0:

<layoutdefault spacing="6" margin="11"/>

That section has a GUI and the XML is not editable. Any way that change can be done?

Hi @Arqam

I thought you wrote the XML. Then see above:

@Venkatesh-V @m-sue
How can I do that, I know for my QLabel containing the image I can do
ui->label_image->setContentsMargins(0,0,0,0);

Constructor :

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    this->setFixedSize(700,700);
    ui->setupUi(this);
    ui->label_image->setContentsMargins(0,0,0,0);
}

So how can we change for main layout also, as just changing the value for label didn't do any thing.

@Arqam ,

First add your label to main layout and then call,

mainLayout->setContentMargins(-1,-1,-1,-1);

@Vinod-Kuntoji
I did :

this->setContentsMargins(-1,-1,-1,-1);
ui->label_image->setContentsMargins(0,0,0,0);

What it did is just that a bit to the left (and other direction) the margin is reduced.
When I give the default value i.e. -11 that is given in the XML then it starts from the leftmost region.
But when given for the top position i.e (-11,-11,0,0) QLabel doesn't start from the topmost part.

@Arqam ,

I tried like this.

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
mLabel = new QLabel(this);
mLayout = new QVBoxLayout(this);

QPixmap pix(":/image.PNG");
mLabel->setPixmap(pix);

mLayout->addWidget(mLabel);

// mLayout->setContentsMargins(0,0,0,0);
mLayout->setMargin(0);
mLayout->setSpacing(0);
mLayout->setAlignment(mLabel,Qt::AlignTop);
QWidget *widget = new QWidget(this);
widget->setLayout(mLayout);

this->setCentralWidget(widget);

}

There is a toolbar on top of the label, thats why it is showing some space on top of label. If you dont want the toolbar then remove it.

@Vinod-Kuntoji said in QLabel not starting from 0,0:

this->setCentralWidget(widget);

My widget main window is not having a toolbar, it was having a status bar which I removed.
The structure of my window is like this :


If going by your example my mLayout should be Central Widget?
