<hr><a name="details"></a><h2>Detailed Description</h2>
The QInputDialog class provides a simple convenience dialog to get a single value from the user.
<p> The QInputDialog is a simple dialog which can be used if you need to
get a single input value from the user. The input value can be a
string, a number or an item from a list. A label has to be set to tell
the user what they should input.
<p> Four static convenience functions are provided:
<a href="#getText">getText</a>(), <a href="#getInteger">getInteger</a>(), <a href="#getDouble">getDouble</a>() and <a href="#getItem">getItem</a>(). All the
functions can be used in a similar way, for example:
<pre>
bool ok = FALSE;
<a href="qstring.html">QString</a> text = QInputDialog::<a href="#getText">getText</a>(
<a href="qobject.html#tr">tr</a>( "Application name" ),
<a href="qobject.html#tr">tr</a>( "Please enter your name" ),
QLineEdit::Normal, <a href="qstring.html#QString-null">QString::null</a>, &ok, this );
if ( ok && !text.<a href="qstring.html#isEmpty">isEmpty</a>() )
;// user entered something and pressed OK
else
;// user entered nothing or pressed Cancel
</pre>

<hr><h2>Member Function Documentation</h2>
<h3 class=fn>double <a name="getDouble"></a>QInputDialog::getDouble ( const <a href="qstring.html">QString</a> & caption, const <a href="qstring.html">QString</a> & label, double num = 0, double from = -2147483647, double to = 2147483647, int decimals = 1, bool * ok = 0, <a href="qwidget.html">QWidget</a> * parent = 0, const char * name = 0 )<tt> [static]</tt>
</h3>
Static convenience function to get a floating point number from the user. <em>caption</em> is the text which is displayed in the title bar of the dialog.
<em>label</em> is the text which is shown to the user (it should mention
what they should input), <em>num</em> is the default floating point number
that the line edit will be set to.
<em>from</em> and <em>to</em> are the minimum and maximum values the user may
choose, and <em>decimals</em> is the maximum number of decimal places the
number may have.
<p> If <em>ok</em> is not-null it will be set to TRUE if the user pressed OK and
FALSE if the user pressed Cancel.
The dialog's parent is <em>parent</em>; the dialog is called <em>name</em>. The
dialog will be modal.
<p> This method returns the floating point number which has been entered
by the user.
<p> Use this static method like this:
<p> <pre>
bool ok = FALSE;
double res = QInputDialog::<a href="#getDouble">getDouble</a>(
<a href="qobject.html#tr">tr</a>( "Application name" ),
<a href="qobject.html#tr">tr</a>( "Please enter a decimal number" ),
33.7, 0, 1000, 2, &ok, this );
if ( ok )
;// user entered something and pressed OK
else
;// user pressed Cancel
</pre>
<h3 class=fn>int <a name="getInteger"></a>QInputDialog::getInteger ( const <a href="qstring.html">QString</a> & caption, const <a href="qstring.html">QString</a> & label, int num = 0, int from = -2147483647, int to = 2147483647, int step = 1, bool * ok = 0, <a href="qwidget.html">QWidget</a> * parent = 0, const char * name = 0 )<tt> [static]</tt>
</h3>
Static convenience function to get an integer input from the user. <em>caption</em> is the text which is displayed in the title bar of the dialog.
<em>label</em> is the text which is shown to the user (it should mention
what they should input), <em>num</em> is the default number which the
spinbox will be set to.
<em>from</em> and <em>to</em> are the minimum and maximum values the user may
choose, and <em>step</em> is the amount by which the values change as the
user presses the arrow buttons to increment or decrement the value.
<p> If <em>ok</em> is not-null it will be set to TRUE if the user pressed OK and
FALSE if the user pressed Cancel.
The dialog's parent is <em>parent</em>; the dialog is called <em>name</em>. The
dialog will be modal.
<p> This method returns the number which has been entered by the user.
<p> Use this static method like this:
<p> <pre>
bool ok = FALSE;
int res = QInputDialog::<a href="#getInteger">getInteger</a>(
<a href="qobject.html#tr">tr</a>( "Application name" ),
<a href="qobject.html#tr">tr</a>( "Please enter a number" ), 22, 0, 1000, 2, &ok, this );
if ( ok )
;// user entered something and pressed OK
else
;// user pressed Cancel
</pre>
<h3 class=fn><a href="qstring.html">QString</a> <a name="getItem"></a>QInputDialog::getItem ( const <a href="qstring.html">QString</a> & caption, const <a href="qstring.html">QString</a> & label, const <a href="qstringlist.html">QStringList</a> & list, int current = 0, bool editable = TRUE, bool * ok = 0, <a href="qwidget.html">QWidget</a> * parent = 0, const char * name = 0 )<tt> [static]</tt>
</h3>
Static convenience function to let the user select an item from a
string list. <em>caption</em> is the text which is displayed in the title
bar of the dialog. <em>label</em> is the text which is shown to the user (it
should mention what they should input). <em>list</em> is the
string list which is inserted into the combobox, and <em>current</em> is the number
of the item which should be the current item. If <em>editable</em> is TRUE
the user can enter their own text; if <em>editable</em> is FALSE the user
may only select one of the existing items.
<p> If <em>ok</em> is not-null it will be set to TRUE if the user pressed OK and
FALSE if the user pressed Cancel.
The dialog's parent is <em>parent</em>; the dialog is called <em>name</em>. The
dialog will be modal.
<p> This method returns the text of the current item, or if <em>editable</em>
is TRUE, the current text of the combobox.
<p> Use this static method like this:
<p> <pre>
<a href="qstringlist.html">QStringList</a> lst;
lst << "First" << "Second" << "Third" << "Fourth" << "Fifth";
bool ok = FALSE;
<a href="qstring.html">QString</a> res = QInputDialog::<a href="#getItem">getItem</a>(
<a href="qobject.html#tr">tr</a>( "Application name" ),
<a href="qobject.html#tr">tr</a>( "Please select an item" ), lst, 1, TRUE, &ok, this );
if ( ok )
;// user selected an item and pressed OK
else
;// user pressed Cancel
</pre>
<h3 class=fn><a href="qstring.html">QString</a> <a name="getText"></a>QInputDialog::getText ( const <a href="qstring.html">QString</a> & caption, const <a href="qstring.html">QString</a> & label, <a href="qlineedit.html#EchoMode-enum">QLineEdit::EchoMode</a> mode = QLineEdit::Normal, const <a href="qstring.html">QString</a> & text = QString::null, bool * ok = 0, <a href="qwidget.html">QWidget</a> * parent = 0, const char * name = 0 )<tt> [static]</tt>
</h3>
Static convenience function to get a string from the user. <em>caption</em> is the text which is displayed in the title bar of the dialog.
<em>label</em> is the text which is shown to the user (it should mention
what they should input), <em>text</em> the default text which is placed in
the line edit. The <em>mode</em> is the echo mode the
line edit will use.
If <em>ok</em> is not-null it will be set to TRUE if the user pressed OK and
FALSE if the user pressed Cancel.
The dialog's parent is <em>parent</em>; the dialog is called <em>name</em>. The

<p> This method returns the text which has been entered in the line edit.
