How to open a new form

Hi there,

I am really new in Qt programming and this forum also.

So I would like to salute all of you.


I am wotking on my first project and I am trying to show an existing form.

My command has like this

Quote:

---

void MainWindow::on_actionAbout_triggered()
{
about a;
a.show();
}

---

When thin function is executed the a window is shown for some miliseconds and then it disapears. It seem like it is not activated anymore.

Why this happen ?


Thank you

Use exec() to show it as a modal dialog.. And why it is currently deleted (basic C++): you create "about" on the stack and thus it gets deleted after the scope "}" ends.

Thank you.
