@DivyaMuthyala Well, documentation: http://doc.qt.io/qt-5/qmessagebox.html
See "Default and Escape Keys" there.

Hi,

Now My QInputDialog is not closing with Enter Key.
Can anyone please give me solution.

@DivyaMuthyala Did you check the link I posted?

[DivyaMuthyala]

Hi,
Yes I have checked , its working for messagebox but not for inputdialog.

@DivyaMuthyala Since QInputDialog is derived from QDialog you should read http://doc.qt.io/qt-5/qdialog.html
"Default Button".

Hi.

This is one of the tricky methods.

QInputDialog    dlg(this);

dlg.setWindowTitle(tr("QInputDialog::getText()"));
dlg.setLabelText(tr("User name:"));
dlg.setTextValue(QDir::home().dirName());
dlg.setOption(QInputDialog::NoButtons);
dlg.open();
QLineEdit   *lineEdit = dlg.findChild<QLineEdit *>();
if (lineEdit)
    connect(lineEdit, &QLineEdit::returnPressed, [&dlg](){
        dlg.accept();
    });
if (dlg.exec() == QDialog::Accepted)
    qDebug() << dlg.textValue();

Hi,

Can we create QInputDialog with only one "ok" button???

[jsulm]

@DivyaMuthyala Maybe you can. But the documentation says:
"Escape Key
If the user presses the Esc key in a dialog, QDialog::reject() will be called. This will cause the window to close: The close event cannot be ignored."
That means: even if there is no Cancel button the user will still be able to use Esc key to close the dialog. Why do you want to remove Cancel button?

Here I am using arm based Embeded device.

My requirement is,InputDialog should by Enter Key,not for Escape Key.

@DivyaMuthyala You can create you own dialogs
