-
- A font is an object which determines the appearance of text, primarily
- when drawing text to a window or device context. A font is determined by
- the following parameters (not all of them have to be specified, of course):
-
- @beginDefList
- @itemdef{Point size, This is the standard way of referring to text size.}
- @itemdef{Family,
- Supported families are:
- @b wxDEFAULT, @b wxDECORATIVE, @b wxROMAN, @b wxSCRIPT, @b wxSWISS, @b wxMODERN.
- @b wxMODERN is a fixed pitch font; the others are either fixed or variable pitch.}
- @itemdef{Style, The value can be @b wxNORMAL, @b wxSLANT or @b wxITALIC.}
- @itemdef{Weight, The value can be @b wxNORMAL, @b wxLIGHT or @b wxBOLD.}
- @itemdef{Underlining, The value can be @true or @false.}
- @itemdef{Face name,
- An optional string specifying the actual typeface to be used. If @NULL,
- a default typeface will chosen based on the family.}
- @itemdef{Encoding,
- The font encoding (see @b wxFONTENCODING_XXX
- constants and the @ref overview_fontencoding for more details)}
- @endDefList
-
- Specifying a family, rather than a specific typeface name, ensures a degree of
- portability across platforms because a suitable font will be chosen for the
- given font family, however it doesn't allow to choose a font precisely as the
- parameters above don't suffice, in general, to identify all the available fonts
- and this is where using the native font descriptions may be helpful - see
- below.
-
- Under Windows, the face name can be one of the installed fonts on the user's
- system. Since the choice of fonts differs from system to system, either choose
- standard Windows fonts, or if allowing the user to specify a face name, store
- the family name with any file that might be transported to a different Windows
- machine or other platform.
-
- @note There is currently a difference between the appearance
- of fonts on the two platforms, if the mapping mode is anything other than
- wxMM_TEXT. Under X, font size is always specified in points. Under MS
- Windows, the unit for text is points but the text is scaled according to the
- current mapping mode. However, user scaling on a device context will also
- scale fonts under both environments.
-
-
-
- @section overview_font_nativeinfo Native font information
-
- An alternative way of choosing fonts is to use the native font description.
- This is the only acceptable solution if the user is allowed to choose the font
- using the wxFontDialog because the selected font cannot
- be described using only the family name and so, if only family name is stored
- permanently, the user would almost surely see a different font in the program
- later.
-
- Instead, you should store the value returned by wxFont::GetNativeFontInfoDesc and pass
- it to wxFont::SetNativeFontInfo later to recreate exactly the same font.
-
- Note that the contents of this string depends on the platform and shouldn't be
- used for any other purpose (in particular, it is not meant to be shown to the
- user). Also please note that although the native font information is currently
- implemented for Windows and Unix (GTK+ and Motif) ports only, all the methods
- are available for all the ports and should be used to make your program work
- correctly when they are implemented later.
