Detailed Description

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

\inmodule QtWidgets

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:

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

Input Dialogs

The \l{dialogs/standarddialogs}{Standard Dialogs} example shows how to use QInputDialog as well as other built-in Qt dialogs.

Member Enumeration Documentation

◆ InputDialogOption

enum QInputDialog::InputDialogOption

Since: 4.5

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

\value NoButtons Don't display \uicontrol{OK} and \uicontrol{Cancel} buttons (useful for "live dialogs"). \value UseListViewForComboBoxItems Use a QListView rather than a non-editable QComboBox for displaying the items set with setComboBoxItems(). \value UsePlainTextEditForTextInput Use a QPlainTextEdit for multiline text input. This value was introduced in 5.2.

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

static

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 \uicontrol OK and to false if the user pressed \uicontrol 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.

Here is the call graph for this function:

◆ getText()

QString QInputDialog::getText	(	QWidget *	parent,
		const QString &	title,
		const QString &	label,
		QLineEdit::EchoMode	mode = `QLineEdit::Normal`,
		const QString &	text = `QString()`,
		bool *	ok = `nullptr`,
		Qt::WindowFlags	flags = `Qt::WindowFlags()`,
		Qt::InputMethodHints	inputMethodHints = `Qt::ImhNone`
	)

static

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 {*ok} will be set to true if the user pressed \uicontrol OK and to false if the user pressed \uicontrol 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.
