ui->textedit->append(): The program has unexpectedly finished

[Stefanoxjx]

Hi, I've a problem with textedit inserted by designer.
Why this line generate the immediate termination of program?

ui->textEdit->append("Hello World...");

What's wrong?

Many thanks.

@Stefanoxjx hard to tell without more code, but my crystalball tells me:

ui->textEdit does not exist at the moment you try to access it.

Hi J.Hilk, you're right.
I tried to append text before to invoke "ui->setupUi(this);"
Many thanks for your illumination and thanks at your crystall ball :)
