|

| 49 | The QFontDialog class provides a dialog widget for selecting a font.
|
|---|
| 50 | <p> The usual way to use this class is to call one of the static convenience
|
|---|
| 51 | functions, e.g. <a href="#getFont">getFont</a>().
|
|---|
| 52 | <p> Examples:
|
|---|
| 53 | <p> <pre>
|
|---|
| 54 | bool ok;
|
|---|
| 55 | <a href="qfont.html">QFont</a> font = QFontDialog::<a href="#getFont">getFont</a>(
|
|---|
| 56 | &ok, QFont( "Helvetica [Cronyx]", 10 ), this );
|
|---|
| 57 | if ( ok ) {
|
|---|
| 58 | // font is set to the font the user selected
|
|---|
| 59 | } else {
|
|---|
| 60 | // the user canceled the dialog; font is set to the initial
|
|---|
| 61 | // value, in this case Helvetica [Cronyx], 10
|
|---|
| 62 | }
|
|---|
| 63 | </pre>
|
|---|
| 64 |
|
|---|
| 65 | <p> The dialog can also be used to set a widget's font directly:
|
|---|
| 66 | <pre>
|
|---|
| 67 | myWidget.setFont( QFontDialog::<a href="#getFont">getFont</a>( 0, myWidget.font() ) );
|
|---|
| 68 | </pre>
|
|---|
| 69 |
|
|---|
| 70 | If the user clicks OK the font they chose will be used for myWidget,
|
|---|
| 71 | and if they click Cancel the original font is used.
|
|---|

| 79 | Executes a modal font dialog and returns a font.
|
|---|
| 80 | <p> If the user clicks OK, the selected font is returned. If the user
|
|---|
| 81 | clicks Cancel, the <em>initial</em> font is returned.
|
|---|
| 82 | <p> The dialog is called <em>name</em>, with the parent <em>parent</em>.
|
|---|
| 83 | <em>initial</em> is the initially selected font.
|
|---|
| 84 | If the <em>ok</em> parameter is not-null, <em>*</em><em>ok</em> is set to TRUE if the
|
|---|
| 85 | user clicked OK, and set to FALSE if the user clicked Cancel.
|
|---|
| 86 | <p> This static function is less flexible than the full QFontDialog
|
|---|
| 87 | object, but is convenient and easy to use.
|
|---|
| 88 | <p> Examples:
|
|---|
| 89 | <pre>
|
|---|
| 90 | bool ok;
|
|---|
| 91 | <a href="qfont.html">QFont</a> font = QFontDialog::<a href="#getFont">getFont</a>( &ok, QFont( "Times", 12 ), this );
|
|---|
| 92 | if ( ok ) {
|
|---|
| 93 | // font is set to the font the user selected
|
|---|
| 94 | } else {
|
|---|
| 95 | // the user canceled the dialog; font is set to the initial
|
|---|
| 96 | // value, in this case Times, 12.
|
|---|
| 97 | }
|
|---|
| 98 | </pre>
|
|---|
| 99 |
|
|---|
| 100 | <p> The dialog can also be used to set a widget's font directly:
|
|---|
| 101 | <pre>
|
|---|
| 102 | myWidget.setFont( QFontDialog::<a href="#getFont">getFont</a>( 0, myWidget.font() ) );
|
|---|
| 103 | </pre>
|
|---|
| 104 |
|
|---|
| 105 | In this example, if the user clicks OK the font they chose will be
|
|---|
| 106 | used, and if they click Cancel the original font is used.
|
|---|
| 107 |
|
|---|
| 108 | <p>Examples: <a href="canvas-chart-example.html#x2881">chart/chartform.cpp</a>, <a href="tutorial2-09.html#x2638">chart/optionsform.cpp</a>, <a href="qfd-example.html#x1981">qfd/fontdisplayer.cpp</a>, <a href="qwerty-example.html#x368">qwerty/qwerty.cpp</a>, and <a href="xform-example.html#x1224">xform/xform.cpp</a>.

|

| 111 | This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
|
|---|
| 112 | <p> Executes a modal font dialog and returns a font.
|
|---|
| 113 | <p> If the user clicks OK, the selected font is returned. If the user
|
|---|
| 114 | clicks Cancel, the Qt default font is returned.
|
|---|
| 115 | <p> The dialog is called <em>name</em>, with parent <em>parent</em>.
|
|---|
| 116 | If the <em>ok</em> parameter is not-null, <em>*</em><em>ok</em> is set to TRUE if the
|
|---|
| 117 | user clicked OK, and FALSE if the user clicked Cancel.
|
|---|
| 118 | <p> This static function is less functional than the full QFontDialog
|
|---|
| 119 | object, but is convenient and easy to use.
|
|---|
| 120 | <p> Example:
|
|---|
| 121 | <pre>
|
|---|
| 122 | bool ok;
|
|---|
| 123 | <a href="qfont.html">QFont</a> font = QFontDialog::<a href="#getFont">getFont</a>( &ok, this );

| 127 | // the user canceled the dialog; font is set to the default
|

| 128 | // application font, QApplication::<a href="qwidget.html#font-prop">font</a>()
