You can create your own messageBox inheriting from dialog with appropriate design. You can customise with your own stuff. We can send that dialog code offline if you share your email id.

@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?

[DivyaMuthyala]

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
