Static functions¶

def getDouble (parent, title, label, value, minValue, maxValue, decimals, flags, step)
def getDouble (parent, title, label[, value=0[, minValue=-2147483647[, maxValue=2147483647[, decimals=1[, flags=Qt.WindowFlags()]]]]])
def getInt (parent, title, label[, value=0[, minValue=-2147483647[, maxValue=2147483647[, step=1[, flags=Qt.WindowFlags()]]]]])
def getItem (parent, title, label, items[, current=0[, editable=true[, flags=Qt.WindowFlags()[, inputMethodHints=Qt.ImhNone]]]])
def getMultiLineText (parent, title, label[, text=”“[, flags=Qt.WindowFlags()[, inputMethodHints=Qt.ImhNone]]])
def getText (parent, title, label[, echo=QLineEdit.Normal[, text=”“[, flags=Qt.WindowFlags()[, inputMethodHints=Qt.ImhNone]]]])

Detailed Description¶

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.

Five static convenience functions are provided: getText() , getMultiLineText() , getInt() , getDouble() , and getItem() . All the functions can be used in a similar way, for example:
text = QInputDialog::getText(self, self.tr("QInputDialog().getText()"),
                                     self.tr("User name:"), QLineEdit.Normal,
                                     QDir().home().dirName(), ok)
if ok and text:
    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.

PySide2.QtWidgets.QInputDialog.InputDialogOption¶

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

Constant	Description
QInputDialog.NoButtons	Don’t display OK and Cancel buttons (useful for “live dialogs”).
QInputDialog.UseListViewForComboBoxItems	Use a `QListView` rather than a non-editable `QComboBox` for displaying the items set with `setComboBoxItems()` .
QInputDialog.UsePlainTextEditForTextInput	Use a `QPlainTextEdit` for multiline text input. This value was introduced in 5.2.

options setOption() testOption()

PySide2.QtWidgets.QInputDialog.InputMode¶

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

Constant	Description
QInputDialog.TextInput	Used to input text strings.
QInputDialog.IntInput	Used to input integers.
QInputDialog.DoubleInput	Used to input floating point numbers with double precision accuracy.

This is an overloaded function.

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. 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 .

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

Use this static function like this:

d = QInputDialog().getDouble(self, self.tr("QInputDialog().getDouble()"),
                                   self.tr("Amount:"), 37.56, -10000, 10000, 2, ok)
if ok:
    doubleLabel.setText(QString("$%1").arg(d))

static PySide2.QtWidgets.QInputDialog.getDouble(parent, title, label[, value=0[, minValue=-2147483647[, maxValue=2147483647[, decimals=1[, flags=Qt.WindowFlags()]]]]])

Parameters

parent – QWidget
title – unicode
label – unicode
value – double
minValue – double
maxValue – double
decimals – int
flags – WindowFlags

Return type

step – int
flags – WindowFlags

Return type

int

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:

i = QInputDialog().getInteger(self, self.tr("QInputDialog().getInteger()"),
                                 self.tr("Percentage:"), 25, 0, 100, 1, ok)

unicode

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 combo box. 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 combo box 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 *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 combo box.

Use this static function like this:

items = [self.tr("Spring"), self.tr("Summer"), self.tr("Fall"), self.tr("Winter")]

item = QInputDialog().getItem(self, self.tr("QInputDialog().getItem()"),
                                     selftr("Season:"), items, 0, False, ok)
