Qt Desinger, lineEdit Problem - SIM-1866423 - May 1, 2015
Hi guys, ım working on QtDesinger to make some basic app.So I got little weird problem today.There following codes ;
PHP Code
<?php
void MainWindow::on_pushButton_2_clicked()
QString str = ui->lineEdit->text();
QMessageBox::information(this, "Hello World!", str);
}
I'm writing to lineedit bla bla etc.. not return anything on my QMessageBox.I already check syntax just in case, but im really do not see anything wrong(but im still not sure)

Does the lineEdit have a string in it?
Are you even sure it's null, and not just an empty string?

What happens if you change it to this?
PHP Code
<?php
#include <iostream>
void MainWindow::on_pushButton_2_clicked()
QString str = ui->lineEdit->text();
QMessageBox::information(this, "Hello World!", "This message should appear!");
std::cout << "String in message box is: \"" << str << "\"" << std::endl;
}
What output do you get in the console?
