## Detailed Description

The QInputDialog class provides a simple convenience dialog to get a single value from the user.

The input value can be a string, a number or an item from a list. A label must be set to tell the user what they should enter.

Four static convenience functions are provided: getText(), getInt(), getDouble(), and getItem(). All the functions can be used in a similar way, for example:

         bool ok;
         QString text = QInputDialog.getText(this, tr("QInputDialog.getText()"),
                                              tr("User name:"), QLineEdit.Normal,
                                              QDir.home().dirName(), &ok);
         if (ok && !text.isEmpty())
             textLabel->setText(text);

The `ok` variable is set to true if the user clicks OK; otherwise it is set to false.

The Standard Dialogs example shows how to use QInputDialog as well as other built-in Qt dialogs.

## Type Documentation

### QInputDialog.InputDialogOption

This enum specifies various options that affect the look and feel of an input dialog.

Constant | Value | Description
--- | --- | ---
`QInputDialog.NoButtons` | `0x00000001` | Don't display OK and Cancel buttons. (Useful for "live dialogs".)
`QInputDialog.UseListViewForComboBoxItems` | `0x00000002` | Use a QListView rather than a non-editable QComboBox for displaying the items set with setComboBoxItems().

This enum was introduced or modified in Qt 4.5.

The InputDialogOptions type is a typedef for QFlags<InputDialogOption>. It stores an OR combination of InputDialogOption values.

See also options, setOption(), and testOption().

### QInputDialog.InputMode

This enum describes the different modes of input that can be selected for the dialog.

Constant | Value | Description
--- | --- | ---
`QInputDialog.TextInput` | `0` | Used to input text strings.
`QInputDialog.IntInput` | `1` | Used to input integers.
`QInputDialog.DoubleInput` | `2` | Used to input floating point numbers with double precision accuracy.

This enum was introduced or modified in Qt 4.5.

See also inputMode.

## Method Documentation

### QInputDialog.__init__ (self, QWidget parent = None, Qt.WindowFlags flags = 0)

The parent argument, if not None, causes self to be owned by Qt instead of PyQt.

Constructs a new input dialog with the given parent and window flags.

This function was introduced in Qt 4.5.

### QString QInputDialog.cancelButtonText (self)

### QStringList QInputDialog.comboBoxItems (self)

### QInputDialog.done (self, int result)

Reimplemented from QDialog.done().

Closes the dialog and sets its result code to result. If this dialog is shown with exec_(), done() causes the local event loop to finish, and exec_() to return result.

See also QDialog.done().

### int QInputDialog.doubleDecimals (self)

### float QInputDialog.doubleMaximum (self)

### float QInputDialog.doubleMinimum (self)

### float QInputDialog.doubleValue (self)

### (float, bool ok) QInputDialog.getDouble (QWidget parent, QString title, QString label, float value = 0, float min = -2147483647, float max = 2147483647, int decimals = 1, Qt.WindowFlags flags = 0)

Static convenience function to get a floating point number from the user.

title is the text which is displayed in the title bar of the dialog. label is the text which is shown to the user (it should say what should be entered). value is the default floating point number that the line edit will be set to. min and max are the minimum and maximum values the user may choose. decimals is the maximum number of decimal places the number may have.

If ok is nonnull, *ok will be set to true if the user pressed OK and to false if the user pressed Cancel. The dialog's parent is parent. The dialog will be modal and uses the widget flags.

This function returns the floating point number which has been entered by the user.

Use this static function like this:

         bool ok;
         double d = QInputDialog.getDouble(this, tr("QInputDialog.getDouble()"),
                                            tr("Amount:"), 37.56, -10000, 10000, 2, &ok);
         if (ok)
             doubleLabel->setText(QString("$%1").arg(d));

Warning: Do not delete parent during the execution of the dialog. If you want to do this, you should create the dialog yourself using one of the QInputDialog constructors.

See also getText(), getInt(), and getItem().

### (int, bool ok) QInputDialog.getInt (QWidget parent, QString title, QString label, int value = 0, int min = -2147483647, int max = 2147483647, int step = 1, Qt.WindowFlags flags = 0)

Static convenience function to get an integer input from the user.

title is the text which is displayed in the title bar of the dialog. label is the text which is shown to the user (it should say what should be entered). value is the default integer which the spinbox will be set to. min and max are the minimum and maximum values the user may choose. step is the amount by which the values change as the user presses the arrow buttons to increment or decrement the value.

If ok is nonnull *ok will be set to true if the user pressed OK and to false if the user pressed Cancel. The dialog's parent is parent. The dialog will be modal and uses the widget flags.

On success, this function returns the integer which has been entered by the user; on failure, it returns the initial value.

Use this static function like this:

         bool ok;
         int i = QInputDialog.getInt(this, tr("QInputDialog.getInteger()"),
                                      tr("Percentage:"), 25, 0, 100, 1, &ok);
         if (ok)
             integerLabel->setText(tr("%1%").arg(i));

Warning: Do not delete parent during the execution of the dialog. If you want to do this, you should create the dialog yourself using one of the QInputDialog constructors.

This function was introduced in Qt 4.5.

See also getText(), getDouble(), and getItem().

### (int, bool ok) QInputDialog.getInteger (QWidget parent, QString title, QString label, int value = 0, int min = -2147483647, int max = 2147483647, int step = 1, Qt.WindowFlags flags = 0)

### (QString, bool ok) QInputDialog.getItem (QWidget parent, QString title, QString label, QStringList list, int current = 0, bool editable = True, Qt.WindowFlags flags = 0)

Static convenience function to let the user select an item from a string list.

title is the text which is displayed in the title bar of the dialog. label is the text which is shown to the user (it should say what should be entered). items is the string list which is inserted into the combobox. current is the number of the item which should be the current item. inputMethodHints is the input method hints that will be used if the combobox is editable and an input method is active.

If editable is true the user can enter their own text; otherwise the user may only select one of the existing items.

If ok is nonnull *a ok will be set to true if the user pressed OK and to false if the user pressed Cancel. The dialog's parent is parent. The dialog will be modal and uses the widget flags.

This function returns the text of the current item, or if editable is true, the current text of the combobox.

Use this static function like this:

         QStringList items;
         items << tr("Spring") << tr("Summer") << tr("Fall") << tr("Winter");

         bool ok;
         QString item = QInputDialog.getItem(this, tr("QInputDialog.getItem()"),
                                              tr("Season:"), items, 0, false, &ok);
         if (ok && !item.isEmpty())
             itemLabel->setText(item);

Warning: Do not delete parent during the execution of the dialog. If you want to do this, you should create the dialog yourself using one of the QInputDialog constructors.

See also getText(), getInt(), and getDouble().

### (QString, bool ok) QInputDialog.getItem (QWidget parent, QString title, QString label, QStringList list, int current, bool editable, Qt.WindowFlags flags, Qt.InputMethodHints inputMethodHints)

### (QString, bool ok) QInputDialog.getText (QWidget parent, QString title, QString label, QLineEdit.EchoMode mode = QLineEdit.Normal, QString text = '', Qt.WindowFlags flags = 0)

Static convenience function to get a string from the user.

title is the text which is displayed in the title bar of the dialog. label is the text which is shown to the user (it should say what should be entered). text is the default text which is placed in the line edit. mode is the echo mode the line edit will use. inputMethodHints is the input method hints that will be used in the edit widget if an input method is active.

If ok is nonnull *a ok will be set to true if the user pressed OK and to false if the user pressed Cancel. The dialog's parent is parent. The dialog will be modal and uses the specified widget flags.

If the dialog is accepted, this function returns the text in the dialog's line edit. If the dialog is rejected, a null QString is returned.

Use this static function like this:

         bool ok;
         QString text = QInputDialog.getText(this, tr("QInputDialog.getText()"),
                                              tr("User name:"), QLineEdit.Normal,
                                              QDir.home().dirName(), &ok);
         if (ok && !text.isEmpty())
             textLabel->setText(text);

Warning: Do not delete parent during the execution of the dialog. If you want to do this, you should create the dialog yourself using one of the QInputDialog constructors.
