Detailed Description#

Warning

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, ok = QInputDialog.getText(self, "QInputDialog.getText()",
                                "User name:", QLineEdit.Normal,
                                QDir.home().dirName())
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.

class 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()

class InputMode#

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.

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, ok = QInputDialog.getDouble(self, "QInputDialog::getDouble()",
                               "Amount:", 37.56, -10000, 10000, 2,
                               Qt.WindowFlags(), 1)
if ok:
   doubleLabel.setText(f"${d}")
static getInt(parent, title, label[, value=0[, minValue=-2147483647[, maxValue=2147483647[, step=1[, flags=Qt.WindowFlags()]]]]])#
Parameters:
  • parentQWidget

  • title – str

  • label – str

  • value – int

  • minValue – int

  • maxValue – int

  • step – int

  • flags – Combination of WindowType

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, ok = QInputDialog.getInt(self, "QInputDialog::getInt()",
                            "Percentage:", 25, 0, 100, 1)
if ok:
    integerLabel.setText(f"{i}")
static getItem(parent, title, label, items[, current=0[, editable=true[, flags=Qt.WindowFlags()[, inputMethodHints=Qt.ImhNone]]]])#
Parameters:
  • parentQWidget

  • title – str

  • label – str

  • items – list of strings

  • current – int

  • editable – bool

  • flags – Combination of WindowType

  • inputMethodHints – Combination of InputMethodHint

Return type:

str

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 = ["Spring", "Summer", "Fall", "Winter"]
item, ok = QInputDialog.getItem(self, "QInputDialog::getItem()",
                                "Season:", items, 0, False)
if ok and item:
    itemLabel.setText(item)
static getMultiLineText(parent, title, label[, text=""[, flags=Qt.WindowFlags()[, inputMethodHints=Qt.ImhNone]]])#
Parameters:
Return type:

str

Static convenience function to get a multiline 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 plain text edit. inputMethodHints is the input method hints that will be used in the edit widget if an input method is active.

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 specified widget flags.

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

Use this static function like this:

text, ok = QInputDialog.getMultiLineText(self, "QInputDialog.getMultiLineText()", ""
                                         "Address:", "John Doe\nFreedom Street")
if ok and text:
