Detailed Description

The QInputDialog class provides a dialog to accept 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 methods are also available: getText(), getInt(), getDouble(), and getItem().

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.

Member Typedef Documentation

QInputDialog::InputDialogOptions

Typedef for QFlags<InputDialogOption> which contains an OR combination of InputDialogOption values.

Refer to QInputDialog::InputDialogOption for the enum documentation.

Member Enumeration Documentation

enum QInputDialog::InputDialogOption

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

Constant	Value	Description
QInputDialog::NoButtons	0x00000001	Do not 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().
QInputDialog::UsePlainTextEditForTextInput	0x00000004	Use a QPlainTextEdit for multiline text input.

See also: options, setOption(), testOption()

enum 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.

See also: inputMode

Constructor & Destructor Documentation

QInputDialog::QInputDialog	(	QWidget *	parent = `nullptr`,
		Qt::WindowFlags	flags = `Qt::EmptyFlag`
	)

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

QInputDialog::~QInputDialog ( )

Destroys the input dialog.

Method Documentation

QString QInputDialog::cancelButtonText ( ) const

Returns the value of the property.

QStringList QInputDialog::comboBoxItems ( ) const

Returns the value of the property.

void QInputDialog::done ( int result )

override

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 ( ) const

Returns the value of the property.

double QInputDialog::doubleMaximum ( ) const

Returns the value of the property.

double QInputDialog::doubleMinimum ( ) const

Returns the value of the property.

double QInputDialog::doubleValue ( ) const

Returns the value of the property.

void QInputDialog::doubleValueChanged ( double value )

signal

This signal is emitted whenever the double value changes in the dialog. The current value is specified by value. This signal is only relevant when the input dialog is used in DoubleInput mode.

void QInputDialog::doubleValueSelected ( double value )

signal

This signal is emitted whenever the user selects a double value by accepting the dialog, for example, by clicking the OK button. The selected value is specified by value. This signal is only relevant when the input dialog is used in DoubleInput mode.

double QInputDialog::getDouble	(	QWidget *	parent,
		const QString &	title,
		const QString &	label,
		double	value = `0`,
		double	minValue = `-2147483647`,
		double	maxValue = `2147483647`,
		int	decimals = `1`,
		bool *	ok = `nullptr`,
		Qt::WindowFlags	flags = `Qt::EmptyFlag`
	)

static

Static method to get a floating point number from the user.

The title is the text which is displayed in the title bar of the dialog. The label is the text which is shown to the user. The value is the default floating point number that the line edit will be set to. The minValue and maxValue are the minimum and maximum values the user may choose. The decimals is the maximum number of decimal places the number may have.

If ok is not a nullptr it 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 method returns the floating point number which has been entered by the user.

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

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

Static method to get an integer input from the user.

The title is the text which is displayed in the title bar of the dialog. The label is the text which is shown to the user. The value is the default integer which the spinbox will be set to. The minValue and maxValue are the minimum and maximum values the user may choose. The 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 not a nullptr it 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 method returns the integer which has been entered by the user. On failure it returns the passed value.

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

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

static

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

The title is the text which is displayed in the title bar of the dialog. The label is the text which is shown to the user. The items is the string list which is inserted into the combobox. The current is the number of the item which should be the current item. The 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 not a nullptr it 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 method returns the text of the current item or if editable is true, the current text of the combobox.

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);
}

static

Used to get a multiline string from the user. The parameter parent is used as the parent of this dialog. The dialog will be modal and uses the specified widget flags.

The parameter title is the text which is displayed in the title bar of the dialog. The label is the text which describes what type of data is being requested from the users. The text parameter is the default text which is placed in the plain text edit. The inputMethodHints is the a hint that will be used in the edit widget if an input method is active.

If ok is not null then the value it points to will be set to true if the user pressed OK and to false if the user pressed CANCEL. If the user presses OK this method will return the text in the dialog's plain text edit. If the dialog is rejected, an empty QString is returned.

bool ok;
QString text = QInputDialog::getMultiLineText(this, "QInputDialog::getMultiLineText()", "Address:", "100 Main Street", &ok);
 
if (ok && ! text.isEmpty()) {
  multiLineTextLabel->setText(text);

Static method to get a string from the user.

The title is the text which is displayed in the title bar of the dialog. The label is the text which is shown to the user. The text is the default text which is placed in the line edit. The echoMode is the echo mode the line edit will use. The inputMethodHints is the input method hints that will be used in the edit widget if an input method is active.

If ok is not a nullptr it 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 method returns the text in the dialog's line edit. If the dialog is rejected, an empty QString is returned.
