DESCRIPTION
The QInputDialog class provides a simple convenience dialog to get 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 convenience functions are provided: getText(),
getInteger(), getDouble() and getItem(). All the functions can be used
in a similar way, for example:
bool ok;
QString text = QInputDialog::getText(
"MyApp 3000", "Enter your name:", QLineEdit::Normal,
QString::null, &ok, this );
if ( ok && !text.isEmpty() ) {
// user entered something and pressed OK
} else {
// user entered nothing or pressed Cancel
}

MEMBER FUNCTION DOCUMENTATIONdouble QInputDialog::getDouble ( const QString & caption, const QString &
label, double value = 0, double minValue = -2147483647, double maxValue
= 2147483647, int decimals = 1, bool * ok = 0, QWidget * parent = 0,
const char * name = 0 ) [static]
Static convenience function to get a floating point number from the
user. caption 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. minValue and maxValue are the
minimum and maximum values the user may choose, and decimals is the
maximum number of decimal places the number may have.
If ok is not-null *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 is called name. The dialog will be modal.
This function returns the floating point number which has been entered
by the user.
Use this static function like this:
bool ok;
double res = QInputDialog::getDouble(
"MyApp 3000", "Enter a decimal number:", 33.7, 0,
1000, 2, &ok, this );
if ( ok ) {
// user entered something and pressed OK
} else {
// user pressed Cancel
}
int QInputDialog::getInteger ( const QString & caption, const QString & label,
int value = 0, int minValue = -2147483647, int maxValue = 2147483647,
int step = 1, bool * ok = 0, QWidget * parent = 0, const char * name =
0 ) [static]
Static convenience function to get an integer input from the user.
caption 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. minValue and maxValue are the minimum and maximum values the user
may choose, and 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-null *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 is called name. The dialog will be modal.
This function returns the integer which has been entered by the user.
Use this static function like this:
bool ok;
int res = QInputDialog::getInteger(
"MyApp 3000", "Enter a number:", 22, 0, 1000, 2,
&ok, this );
if ( ok ) {
// user entered something and pressed OK
} else {
// user pressed Cancel
}
QString QInputDialog::getItem ( const QString & caption, const QString &
label, const QStringList & list, int current = 0, bool editable = TRUE,
bool * ok = 0, QWidget * parent = 0, const char * name = 0 ) [static]
Static convenience function to let the user select an item from a
string list. caption 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). list is the string list which is inserted into
the combobox, and current is the number of the item which should be the
current item. If editable is TRUE the user can enter their own text; if
editable is FALSE the user may only select one of the existing items.
If ok is not-null *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 is called name. The dialog will be modal.
This function returns the text of the current item, or if editable is
TRUE, the current text of the combobox.
Use this static function like this:
QStringList lst;
lst << "First" << "Second" << "Third" << "Fourth" << "Fifth";
bool ok;
QString res = QInputDialog::getItem(
"MyApp 3000", "Select an item:", lst, 1, TRUE, &ok,
this );
if ( ok ) {
// user selected an item and pressed OK
} else {
// user pressed Cancel
}
QString QInputDialog::getText ( const QString & caption, const QString &
label, QLineEdit::EchoMode mode = QLineEdit::Normal, const QString &
text = QString::null, bool * ok = 0, QWidget * parent = 0, const char *
name = 0 ) [static]
Static convenience function to get a string from the user. caption 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.
The mode is the echo mode the line edit will use. If ok is not-null *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 is called
name. The dialog will be modal.
This function returns the text which has been entered in the line edit.
It will not return an empty string.
Use this static function like this:
bool ok;
QString text = QInputDialog::getText(
"MyApp 3000", "Enter your name:", QLineEdit::Normal,
QString::null, &ok, this );
if ( ok && !text.isEmpty() ) {
// user entered something and pressed OK
} else {
// user entered nothing or pressed Cancel
}
