Is it possible to put a QGroupBox into a cell of QTableWidget ??

[jiapei100]

Hi, all:

I followed the code on page http://doc.qt.digia.com/4.7-snapshot...-groupbox.html . The code patch is attached:

QGroupBox *groupBox = new QGroupBox(tr("Exclusive Radio Buttons"));
 
     QRadioButton *radio1 = new QRadioButton(tr("&Radio button 1"));
     QRadioButton *radio2 = new QRadioButton(tr("R&adio button 2"));
     QRadioButton *radio3 = new QRadioButton(tr("Ra&dio button 3"));
 
     radio1->setChecked(true);
     QVBoxLayout *vbox = new QVBoxLayout;
     vbox->addWidget(radio1);
     vbox->addWidget(radio2);
     vbox->addWidget(radio3);
     vbox->addStretch(1);
     groupBox->setLayout(vbox);

QGroupBox *groupBox = new QGroupBox(tr("Exclusive Radio Buttons"));

     QRadioButton *radio1 = new QRadioButton(tr("&Radio button 1"));
     QRadioButton *radio2 = new QRadioButton(tr("R&adio button 2"));
     QRadioButton *radio3 = new QRadioButton(tr("Ra&dio button 3"));

     radio1->setChecked(true);
     QVBoxLayout *vbox = new QVBoxLayout;
     vbox->addWidget(radio1);
     vbox->addWidget(radio2);
     vbox->addWidget(radio3);
     vbox->addStretch(1);
     groupBox->setLayout(vbox);

To copy to clipboard, switch view to plain text mode 

Since groupBox is a QWidget, I would like add groupBox into a widget cell as :

ui->tableWidget->setCellWidget(0, 4, groupBox);

ui->tableWidget->setCellWidget(0, 4, groupBox);

To copy to clipboard, switch view to plain text mode 

But it seems this doesn't work for me at all. Those radios can't show up at all.

Can anybody help to let me know if it's possible to put a groupBox into a tableWidget cell? If so, how?


Thanks
Pei

Yes it is possible, just make sure the table has the specified row, and column.

ui->tableWidget->setRowCount(1);
ui->tableWidget->setColumnCount(5);

ui->tableWidget->setRowCount(1);
ui->tableWidget->setColumnCount(5);

Thanks Santosh Reddy.

This doesn't work for me at all... I'm pretty sure my tableWidget does have 6 columns and 6 rows.
Please refer to http://qt-project.org/forums/viewthread/24742/#114245, somebody answered my question, but that's not the solution I want.


Any other suggestions please?


Thank you

Then I will say that you are missing somthing to mention.
What does the output look like ?
Are you sure setCellWidget is being called ?

Make sure the cell is large enough to show the widget otherwise you will just get the top left corner of the group box.

#include <QtGui>
 
int main(int argc, char **argv)
{
    QApplication app(argc, argv);
 
    QTableWidget w(6, 6);
    QGroupBox *groupBox = new QGroupBox("Radio Buttons", &w);
    QRadioButton *radio1 = new QRadioButton("&Radio button 1", &w);
    QRadioButton *radio2 = new QRadioButton("R&adio button 2", &w);
    QRadioButton *radio3 = new QRadioButton("Ra&dio button 3", &w);
    radio1->setChecked(true);
    QVBoxLayout *vbox = new QVBoxLayout(groupBox);

// might be good places to start
 
    w.show();
 
    return app.exec();
}
