<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>
<p>Four static convenience functions are provided: <a href="qinputdialog.html#getText">getText</a>(), <a href="qinputdialog.html#getInteger">getInteger</a>(), <a href="qinputdialog.html#getDouble">getDouble</a>() and <a href="qinputdialog.html#getItem">getItem</a>(). All the functions can be used in a similar way, for example:</p>
<pre>
bool ok;
QString text = QInputDialog.getText(this, tr("QInputDialog.getText()"),
tr("User name:"), QLineEdit.Normal,
QDir.home().dirName(), &ok);
if (ok && !text.isEmpty())
textLabel->setText(text);
</pre>
<p>The <tt>ok</tt> variable is set to true if the user clicks <b>OK</b>; otherwise it is set to false.</p>
<p align="center"><img alt="Input Dialogs" src="images/inputdialogs.png" /></p>
<p>The <a href="dialogs-standarddialogs.html">Standard Dialogs</a> example shows how to use QInputDialog as well as other built-in Qt dialogs.</p>
<p>See also <a href="qmessagebox.html">QMessageBox</a>.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="getDouble" />(float, bool <i>ok</i>) QInputDialog.getDouble (<a href="qwidget.html">QWidget</a> <i>parent</i>, <a href="qstring.html">QString</a> <i>title</i>, <a href="qstring.html">QString</a> <i>label</i>, float <i>value</i> = 0, float <i>minValue</i> = -2147483647, float <i>maxValue</i> = 2147483647, int <i>decimals</i> = 1, <a href="qt-windowflags.html">Qt.WindowFlags</a> <i>f</i> = 0)</h3><p>Static convenience function to get a floating point number from the user. <i>title</i> is the text which is displayed in the title bar of the dialog. <i>label</i> is the text which is shown to the user (it should say what should be entered). <i>value</i> is the default floating point number that the line edit will be set to. <i>minValue</i> and <i>maxValue</i> are the minimum and maximum values the user may choose, and <i>decimals</i> is the maximum number of decimal places the number may have.</p>
<p>If <i>ok</i> is non-null, *<i>ok</i> will be set to true if the user pressed OK and to false if the user pressed <b>Cancel</b>. The dialog's parent is <i>parent</i>. The dialog will be modal and uses the widget flags <i>f</i>.</p>
<p>This function returns the floating point number which has been entered by the user.</p>
<p>Use this static function like this:</p>
<pre>
bool ok;
double d = QInputDialog.getDouble(this, tr("QInputDialog.getDouble()"),
tr("Amount:"), 37.56, -10000, 10000, 2, &ok);
if (ok)
doubleLabel->setText(QString("$%1").arg(d));

<h3 class="fn"><a name="getInteger" />(int, bool <i>ok</i>) QInputDialog.getInteger (<a href="qwidget.html">QWidget</a> <i>parent</i>, <a href="qstring.html">QString</a> <i>title</i>, <a href="qstring.html">QString</a> <i>label</i>, int <i>value</i> = 0, int <i>minValue</i> = -2147483647, int <i>maxValue</i> = 2147483647, int <i>step</i> = 1, <a href="qt-windowflags.html">Qt.WindowFlags</a> <i>f</i> = 0)</h3><p>Static convenience function to get an integer input from the user. <i>title</i> is the text which is displayed in the title bar of the dialog. <i>label</i> is the text which is shown to the user (it should say what should be entered). <i>value</i> is the default integer which the spinbox will be set to. <i>minValue</i> and <i>maxValue</i> are the minimum and maximum values the user may choose, and <i>step</i> is the amount by which the values change as the user presses the arrow buttons to increment or decrement the value.</p>
<p>If <i>ok</i> is non-null *<i>ok</i> will be set to true if the user pressed <b>OK</b> and to false if the user pressed <b>Cancel</b>. The dialog's parent is <i>parent</i>. The dialog will be modal and uses the widget flags <i>f</i>.</p>
<p>This function returns the integer which has been entered by the user.</p>
<p>Use this static function like this:</p>
<pre>
bool ok;
int i = QInputDialog.getInteger(this, tr("QInputDialog.getInteger()"),
tr("Percentage:"), 25, 0, 100, 1, &ok);
if (ok)
integerLabel->setText(tr("%1%").arg(i));

<h3 class="fn"><a name="getItem" />(<a href="qstring.html">QString</a>, bool <i>ok</i>) QInputDialog.getItem (<a href="qwidget.html">QWidget</a> <i>parent</i>, <a href="qstring.html">QString</a> <i>title</i>, <a href="qstring.html">QString</a> <i>label</i>, <a href="qstringlist.html">QStringList</a> <i>list</i>, int <i>current</i> = 0, bool <i>editable</i> = True, <a href="qt-windowflags.html">Qt.WindowFlags</a> <i>f</i> = 0)</h3><p>Static convenience function to let the user select an item from a string list. <i>title</i> is the text which is displayed in the title bar of the dialog. <i>label</i> is the text which is shown to the user (it should say what should be entered). <i>list</i> is the string list which is inserted into the combobox, and <i>current</i> is the number of the item which should be the current item. If <i>editable</i> is true the user can enter their own text; if <i>editable</i> is false the user may only select one of the existing items.</p>
<p>If <i>ok</i> is non-null <i>*a</i> ok will be set to true if the user pressed OK and to false if the user pressed <b>Cancel</b>. The dialog's parent is <i>parent</i>. The dialog will be modal and uses the widget flags <i>f</i>.</p>
<p>This function returns the text of the current item, or if <i>editable</i> is true, the current text of the combobox.</p>

<pre>
