Problem with UI showing

[PoziomeQ]

Hi. I have a small problem.
my code:

ka::ka(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::ka)
{
 ui->setupUi(this);
    QTextCodec::setCodecForTr(QTextCodec::codecForName("UTF-8"));
    QTextCodec::setCodecForCStrings(QTextCodec::codecForName("UTF-8"));
    QTextCodec::setCodecForLocale(QTextCodec::codecForName("UTF-8"));
go();
 
}

ka::ka(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::ka)
{
 ui->setupUi(this);
    QTextCodec::setCodecForTr(QTextCodec::codecForName("UTF-8"));
    QTextCodec::setCodecForCStrings(QTextCodec::codecForName("UTF-8"));
    QTextCodec::setCodecForLocale(QTextCodec::codecForName("UTF-8"));
go();

}

To copy to clipboard, switch view to plain text mode 

The function go(); is running before UI is showed but I dont want it like that.
The Ui should be show first, and then go(); should be run.
Could You help me?
Sorry for my bad english
Thanks

call go() with a single shot timer or better reimp the showEvent and then start go().

i think time isnt problem here.

ka::ka(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::ka)
    {
    ui->setupUi(this);
    QTextCodec::setCodecForTr(QTextCodec::codecForName("UTF-8"));
    QTextCodec::setCodecForCStrings(QTextCodec::codecForName("UTF-8"));
    QTextCodec::setCodecForLocale(QTextCodec::codecForName("UTF-8"));
    QTimer::singleShot(1000, this, SLOT(quit()));
    go();
 
    }

ka::ka(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::ka)
    {
    ui->setupUi(this);
    QTextCodec::setCodecForTr(QTextCodec::codecForName("UTF-8"));
    QTextCodec::setCodecForCStrings(QTextCodec::codecForName("UTF-8"));
    QTextCodec::setCodecForLocale(QTextCodec::codecForName("UTF-8"));
    QTimer::singleShot(1000, this, SLOT(quit()));
    go();
     
    }

To copy to clipboard, switch view to plain text mode 

it waits a few sec, do go(); function, a then shows ui

and i dont know how to use showEvent...

ka::ka(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::ka)
    {
    ui->setupUi(this);
    QTextCodec::setCodecForTr(QTextCodec::codecForName("UTF-8"));
    QTextCodec::setCodecForCStrings(QTextCodec::codecForName("UTF-8"));
    QTextCodec::setCodecForLocale(QTextCodec::codecForName("UTF-8"));
    QWidget::showEvent(this);
    go();
 
    }

ka::ka(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::ka)
    {
    ui->setupUi(this);
    QTextCodec::setCodecForTr(QTextCodec::codecForName("UTF-8"));
    QTextCodec::setCodecForCStrings(QTextCodec::codecForName("UTF-8"));
    QTextCodec::setCodecForLocale(QTextCodec::codecForName("UTF-8"));
    QWidget::showEvent(this);
    go();
     
    }

I tried like that but it dosnt work.

Make go() a slot and call that, not quit()...
