Access the subTab Widget in Main TabWidget

[hasnatzaidi]

hi all, I use the following code in QDialog

void Dialog::loadForm()
 
{
    ui->volumeSlider->setValue(findItem("AUDIO_LEVEL").toInt());
    ui->txtKeyBoad->setText(findItem("KEYBOARD_MAP"));
    ui->txtTimeZone->setText(findItem("TIME_ZONE"));
}

void Dialog::loadForm()

{
    ui->volumeSlider->setValue(findItem("AUDIO_LEVEL").toInt());
    ui->txtKeyBoad->setText(findItem("KEYBOARD_MAP"));
    ui->txtTimeZone->setText(findItem("TIME_ZONE"));
}

To copy to clipboard, switch view to plain text mode 

To Access the Dialog consisting Volume Slider and Text Boxes, it Run Correctly.
Now I switch to MainWindow Form using this code

ui->general_tab->horizontalSlider->setValue(findItem("AUDIO_LEVEL").toInt());

ui->general_tab->horizontalSlider->setValue(findItem("AUDIO_LEVEL").toInt());

To copy to clipboard, switch view to plain text mode 

it can't access the subTab
where my maintab ObjectName is"general_tab_2" and SubTab ObjName is"general_tab"
Please anyone who tell me that "whats the changes required in this code".
thanks

To display one of your tabs, use QTabWidget::setCurrentIndex() or QTabWidget::setCurrentWidget().
