The TQFontDialog 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 = "ntqfont.html" > TQFont< / a > font = TQFontDialog::< a href = "#getFont" > getFont< / a > (
& ok, TQFont( "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( TQFontDialog::< 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.

< h3 class = fn > < a href = "ntqfont.html" > TQFont< / a > < a name = "getFont" > < / a > TQFontDialog::getFont ( bool * ok, const < a href = "ntqfont.html" > TQFont< / a > & initial, < a href = "tqwidget.html" > TQWidget< / a > * parent = 0, const char * name = 0 )< tt > [static]< / tt >
< / h3 >
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 TQFontDialog
object, but is convenient and easy to use.
< p > Examples:
< pre >
bool ok;
< a href = "ntqfont.html" > TQFont< / a > font = TQFontDialog::< a href = "#getFont" > getFont< / a > ( & ok, TQFont( "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( TQFontDialog::< 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.

< / h3 >
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 TQt 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 TQFontDialog
object, but is convenient and easy to use.
< p > Example:
< pre >
bool ok;
< a href = "ntqfont.html" > TQFont< / a > font = TQFontDialog::< 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, TQApplication::< a href = "tqwidget.html#font-prop" > font< / a > ()
}
