Solving some errors.

thanks a lot mate. it fixed my problem.

:D

How can i get the input from the users??

i have used this code

Code:

---

void Dialog::gettext()
{
QString text = QInputDialog::getText(this, tr("Enter the username"),
                                          tr("User name:"), QLineEdit::Normal);
     ui->dislabel->setText(text);
}

---

but this code pops up a dialog which i dont need.

What i want is, when i add the text in the lineedit, it should be reflected in the label, or

when i add the text in the lineedit, a variable names text has to store it.

so, you need to add QLineEdit to your form and then

Code:

---

...
connect(ui->lineEdit, SIGNAL(textEdited(const QString &)), ui->label, SLOT(setText(const QString &)));
...

---

this code will add a text from lineEdit to label.

Code:

---

...
connect(ui->pushButton, SIGNAL(clicked()), SLOT(getLineEditText()));//get text by clicking on a button
connect(ui->lineEdit, SIGNAL(editingFinished()), SLOT(getLineEditText()));//get text by pressing enter in a lineEdit
//you can also use QLineEdit::returnPressed insted of QLineEdit::editingFinished
...
 
void MyWidget::getLineEditText()
{
     qDebug() << ui->lineEdit->text();
}

connect(ui->lineEdit, SIGNAL(editingFinished()), SLOT(getLineEditText()));//get text by pressing enter in a lineEdit
//you can also use QLineEdit::returnPressed insted of QLineEdit::editingFinished
...
 
void MyWidget::getLineEditText()
{
     const QString myVar = ui->lineEdit->text();
     ui->label->setText(myVar);
}

mate if i want o add a icon into the application, how can it be done?

I have seen .qrc files. I need to store the image in this particular file

The icon i am talking about is the one is that tiny icon that appears at the top left corner of an application.

I think that you should take closer look into Qt Exapmples & Demos and Qt Assistant. There are a lot of exapmples and explanations to all problems you posted here, and it's quite easy find answers there.
