SWT provides the FontDialog class to display the common font selection dialog.
FontDialog's open() method returns a FontData object (or null if the user cancels the dialog), which you can use to create a Font.
SWT uses two classes to represent fonts:
- Font represents the onscreen font, and
- Font objects represent operating system resources, and you must dispose any you create.
- FontData represents the data used to construct the onscreen font.
- FontData objects contain only data, and aren't operating system resources, so they aren't disposed.

FontData fontData = dlg.open();

}

}
Caution: Don't dispose a font while your application is still using it.
