<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 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.
<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;
<a href="qstring.html">QString</a> text = QInputDialog::<a href="#getText">getText</a>(
"MyApp 3000", "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>
<p> <center><img src="inputdialogs.png" alt="Input Dialogs"></center> <p>See also <a href="dialogs.html">Dialog Classes</a>.
<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 value = 0, double minValue = -2147483647, double maxValue = 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 say what should be entered). <em>value</em> is the default
floating point number that the line edit will be set to. <em>minValue</em> and <em>maxValue</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 <em>*</em><em>ok</em> will be set to TRUE if the user
pressed OK and to 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 function returns the floating point number which has been
entered by the user.
<p> Use this static function like this:
<p> <pre>
bool ok;
double res = QInputDialog::<a href="#getDouble">getDouble</a>(
"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
}
</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 value = 0, int minValue = -2147483647, int maxValue = 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 say what should be entered). <em>value</em> is the default
integer which the spinbox will be set to. <em>minValue</em> and <em>maxValue</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 *<em>ok</em> will be set to TRUE if the user
pressed OK and to 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 function returns the integer which has been entered by the user.
<p> Use this static function like this:
<p> <pre>
bool ok;
int res = QInputDialog::<a href="#getInteger">getInteger</a>(
"MyApp 3000", "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 say what should be entered). <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 <em>*</em><em>ok</em> will be set to TRUE if the user
pressed OK and to 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 function returns the text of the current item, or if <em>editable</em> is TRUE, the current text of the combobox.
<p> Use this static function like this:
<p> <pre>
<a href="qstringlist.html">QStringList</a> lst;
lst << "First" << "Second" << "Third" << "Fourth" << "Fifth";
bool ok;
<a href="qstring.html">QString</a> res = QInputDialog::<a href="#getItem">getItem</a>(
"MyApp 3000", "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
say what should be entered). <em>text</em> is 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 <em>*</em><em>ok</em> will be set to TRUE if the
user pressed OK and to 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 function returns the text which has been entered in the line
edit. It will not return an empty string.
<p> Use this static function like this:
<p> <pre>
bool ok;
<a href="qstring.html">QString</a> text = QInputDialog::<a href="#getText">getText</a>(
"MyApp 3000", "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>
