I have a simple question about qt programming.

I want to using the ui file for add component.
For example, add QLabel component by modify ui file.

But text of label is need change.
So I try code llike above...

QLabel *label1 = ui->label;
label->setText("change text");
ui->setupUi(this);

The result is crush.
Crush message is above...

"The program has unexpectedly finished.
The process was ended forcefully."

Can't I using this coding style??

Hi, ui->setupUi(this) creates all the stuff in your window, like the ui->label you're copying, so try to change the order of the statements to:

ui->setupUi(this);
QLabel *label1 = ui->label;
label1->setText("change text");
