Stack widget pages not properly shown.

kishore_hemmady

I have a stackwidget with 5 pages.I also have a comboBox with 5 options corresponding to each page.
I tried this below code but it was not proper.Plz suggest
void MainWindow::on_comboBox_currentIndexChanged(const QString &arg1)
{
if(arg1 == "Video")
{
ui->AudioPage->hide();
ui->TickerPage->hide();
ui->RssPage->hide();
ui->ImagePage->hide();
ui->VideoPage->show();
}
else if(arg1 == "Image")
{
ui->VideoPage->hide();
ui->AudioPage->hide();
ui->TickerPage->hide();
ui->RssPage->hide();
ui->ImagePage->show();
}
else if(arg1 == "RSS")
{
ui->VideoPage->hide();
ui->AudioPage->hide();
ui->TickerPage->hide();
ui->RssPage->show();
ui->ImagePage->hide();
}
else if(arg1 == "Ticker")
{
ui->VideoPage->hide();
ui->AudioPage->hide();
ui->TickerPage->show();
ui->RssPage->hide();
ui->ImagePage->hide();
}
else if(arg1 == "Audio")
{
ui->VideoPage->hide();
ui->AudioPage->show();
ui->TickerPage->hide();
ui->RssPage->hide();
ui->ImagePage->hide();
}
}

usually you controle the stackedwidget and the stackedwidget controlles the pages

assuming your stackedwidget has the ObjectName stackedWidget you can write the following:

void MainWindow::on_comboBox_currentIndexChanged(const QString &arg1)
{
if(arg1 == "Video")
{
    ui->stackedWidget->setCurrentWidget(ui->VideoPage);
}
...
...

if(arg1 == "Audio")
{
   ui->stackedWidget->setCurrentWidget(ui->AudioPage);

}
}

Hi,

An even simpler solution would be to match the combo box index with the QStackedWidget content. Then you can connect them directly.

connect(ui->comboBox, QOverload<int>::of(&QComboBox::currentIndexChanged), ui->stackedWidget, &QStackedWidget::setCurrentIndex);

Way less code and it scales automatically when adding new widgets.
