[Solved] Is NULL check needed for 'ui' in qt designer form class



  • Hi,

    I know that null check is important to avoid any faults in application. But do I have to do null check for my widgets created in qt designer ??

    say...
    @SystemScreen::SystemScreen(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::SystemScreen)
    {
    qDebug() << Q_FUNC_INFO << "Invoked";
    ui->setupUi(this);
    ui->tableNewButton->hide();@

    do I have to make a NULL check for all components when I use them?

    @if (NULL != ui->tableNewButton)
    {
    ui->tableNewButton->hide();
    }@
