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:

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

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

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:

    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 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:

    bool ok;
    QString text = QInputDialog::getMultiLineText(this, tr("QInputDialog::getMultiLineText()"),
                                                  tr("Address:"), "John Doe\nFreedom Street", &ok);
    if (ok && !text.isEmpty())
        multiLineTextLabel->setText(text);

This function was introduced in Qt 5.2.

Reimplements: QDialog::minimumSizeHint() const.

This function connects one of its signals to the slot specified by receiver and member. The specific signal depends on the arguments that are specified in member. These are:

• textValueSelected() if member has a QString for its first argument.

• intValueSelected() if member has an int for its first argument.

• doubleValueSelected() if member has a double for its first argument.

• accepted() if member has NO arguments.

The signal will be disconnected from the slot when the dialog is closed.

Sets the range of double precision floating point values accepted by the dialog when used in DoubleInput mode, with minimum and maximum values specified by min and max respectively.

Sets the range of integer values accepted by the dialog when used in IntInput mode, with minimum and maximum values specified by min and max respectively.

Sets the given option to be enabled if on is true; otherwise, clears the given option.
