The QFontDialog class provides a dialog widget for selecting a font.
|
||
|
|
<p> The usual way to use this class is to call one of the static convenience
|
||
|
|
functions, e.g. <a href="#getFont">getFont</a>().
|
||
|
|
<p> Examples:
|
||
|
|
<p> <pre>
|
||
|
|
bool ok;
|
||
|
|
<a href="qfont.html">QFont</a> font = QFontDialog::<a href="#getFont">getFont</a>(
|
||
|
|
&ok, QFont( "Helvetica [Cronyx]", 10 ), this );
|
||
|
|
if ( ok ) {
|
||
|
|
// font is set to the font the user selected
|
||
|
|
} else {
|
||
|
|
// the user canceled the dialog; font is set to the initial
|
||
|
|
// value, in this case Helvetica [Cronyx], 10
|
||
|
|
}
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p> The dialog can also be used to set a widget's font directly:
|
||
|
|
<pre>
|
||
|
|
myWidget.setFont( QFontDialog::<a href="#getFont">getFont</a>( 0, myWidget.font() ) );
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
If the user clicks OK the font they chose will be used for myWidget,
|
||
|
|
and if they click Cancel the original font is used.
|
||
|
|

|
||
|
|
Executes a modal font dialog and returns a font.
|
||
|
|
<p> If the user clicks OK, the selected font is returned. If the user
|
||
|
|
clicks Cancel, the <em>initial</em> font is returned.
|
||
|
|
<p> The dialog is called <em>name</em>, with the parent <em>parent</em>.
|
||
|
|
<em>initial</em> is the initially selected font.
|
||
|
|
If the <em>ok</em> parameter is not-null, <em>*</em><em>ok</em> is set to TRUE if the
|
||
|
|
user clicked OK, and set to FALSE if the user clicked Cancel.
|
||
|
|
<p> This static function is less flexible than the full QFontDialog
|
||
|
|
object, but is convenient and easy to use.
|
||
|
|
<p> Examples:
|
||
|
|
<pre>
|
||
|
|
bool ok;
|
||
|
|
<a href="qfont.html">QFont</a> font = QFontDialog::<a href="#getFont">getFont</a>( &ok, QFont( "Times", 12 ), this );
|
||
|
|
if ( ok ) {
|
||
|
|
// font is set to the font the user selected
|
||
|
|
} else {
|
||
|
|
// the user canceled the dialog; font is set to the initial
|
||
|
|
// value, in this case Times, 12.
|
||
|
|
}
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p> The dialog can also be used to set a widget's font directly:
|
||
|
|
<pre>
|
||
|
|
myWidget.setFont( QFontDialog::<a href="#getFont">getFont</a>( 0, myWidget.font() ) );
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
In this example, if the user clicks OK the font they chose will be
|
||
|
|
used, and if they click Cancel the original font is used.
|
||
|
|
|
||
|

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
|
||
|
|
<p> Executes a modal font dialog and returns a font.
|
||
|
|
<p> If the user clicks OK, the selected font is returned. If the user
|
||
|
|
clicks Cancel, the Qt default font is returned.
|
||
|
|
<p> The dialog is called <em>name</em>, with parent <em>parent</em>.
|
||
|
|
If the <em>ok</em> parameter is not-null, <em>*</em><em>ok</em> is set to TRUE if the
|
||
|
|
user clicked OK, and FALSE if the user clicked Cancel.
|
||
|
|
<p> This static function is less functional than the full QFontDialog
|
||
|
|
object, but is convenient and easy to use.
|
||
|
|
<p> Example:
|
||
|
|
<pre>
|
||
|
|
bool ok;
|
||
|
|
<a href="qfont.html">QFont</a> font = QFontDialog::<a href="#getFont">getFont</a>( &ok, this );
|
||
|
|
if ( ok ) {
|
||
|
|
// font is set to the font the user selected
|
||
|
|
} else {
|
||
|
|
// the user canceled the dialog; font is set to the default
|
||
|
|
// application font, QApplication::<a href="qwidget.html#font-prop">font</a>()
|
||
|
|
}
