Qpixmaps in Qtablewidget hides untill i select the cell?

[Dreamerzz]

How can i make the pixmap(label) appear in the table without me having to click and select the cell it is in first?

Thanks

[Rachol]

Can you provide some code that shows how you populate the table?

[Dreamerzz]

ui->setupUi(this);
    ui->tableWidget->setSpan(0,0,3,1);
    //-------------
    // IMAGE [QLABEL->PIXMAP]
    //--------------
    QLabel *label00 = new QLabel();
    label00->setPixmap(QPixmap(":/pic.png"));
    label00->setScaledContents(true);
    ui->tableWidget->setCellWidget(0,0,label00);

ui->setupUi(this);
    ui->tableWidget->setSpan(0,0,3,1);
    //-------------
    // IMAGE [QLABEL->PIXMAP]
    //--------------
    QLabel *label00 = new QLabel();
    label00->setPixmap(QPixmap(":/pic.png"));
    label00->setScaledContents(true);
    ui->tableWidget->setCellWidget(0,0,label00);

To copy to clipboard, switch view to plain text mode 

Theres my label for the pixmap.

All right. I have just created a new project in Qt Creator. Used the template for Gui Application. I have added QTableWidget into GUI and set rowCount and columnCount to 10. Then in MainWindow's constructor I did that:

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
 
    for(int i = 0; i < 10;++i)
    {
        for(int j = 0; j < 10;++j)
        {
            QLabel *labelij = new QLabel();
            labelij->setPixmap(QPixmap("3.png"));
            labelij->setScaledContents(true);
            ui->tableWidget->setCellWidget(i,j,labelij);
        }
    }
}

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    for(int i = 0; i < 10;++i)
    {
        for(int j = 0; j < 10;++j)
        {
            QLabel *labelij = new QLabel();
            labelij->setPixmap(QPixmap("3.png"));
            labelij->setScaledContents(true);
            ui->tableWidget->setCellWidget(i,j,labelij);
        }
    }
}

To copy to clipboard, switch view to plain text mode 

I got all the pixmaps without a problem

Wait i have the exact same thing though, so maybe its an issue with my settings in the designer?

[Rachol]

I have used your ui file in my project and it worked...

[Santosh Reddy]

Try this

ui->tableWidget->setCellWidget(0,0,label00);
    ui->tableWidget->resizeColumnsToContents();
    ui->tableWidget->resizeRowsToContents();

ui->tableWidget->setCellWidget(0,0,label00);
    ui->tableWidget->resizeColumnsToContents();
    ui->tableWidget->resizeRowsToContents();

That is really weird, it still isnt working for me... hm

which version of QT? also maybe its the picture im using?

---

Added after 9 minutes:

@Santosh it still does not work.

WHat is weird is that the image appears highlighted

[Rachol]

if you aren't doing anything extra than what you have shown us, I can't quite get: what has selecting and clicking the QLabel has to do with rendering the pixmap. Can you post an image with the pixmap visible? Any pixmap?

[Dreamerzz]

well i added some other labels in other rows and columns, also look above to post#8 to see what i see immediately after running
