+ Simple markup supported by this function can be used to apply different

+
+ For example,
+ @code
+ wxStaticText *text;
+ ...
+ text->SetLabelMarkup("&Bed ∓ "
+ "breakfast "
+ "available HERE");
+ @endcode
+ would show the string using bold, red and big for the corresponding
+ words under wxGTK but will simply show the string "Bed & breakfast
+ available HERE" on the other platforms. In any case, the "B" of "Bed"
+ will be underlined to indicate that it can be used as a mnemonic for
+ this control.
+
+ The supported tags are:
+
+
+ Tag |
+ Description |
+
+
+ <b> |
+ bold text |
+
+
+ <big> |
+ bigger text |
+
+
+ <i> |

+ <s> |
+ strike-through text |
+
+
+ <small> |
+ smaller text |
+
+
+ <tt> |
+ monospaced text |
+
+
+ <u> |
+ underlined text |
+
+
+ <span> |
+ generic formatter tag, see the table below for supported
+ attributes.
+ |
+
+
+
+ Supported @c <span> attributes:
+
+
+ Name |
+ Description |
+
+
+ foreground, fgcolor, color |
+ Foreground text colour, can be a name or RGB value. |
+
+
+ background, bgcolor |
+ Background text colour, can be a name or RGB value. |
+
+
+ font_family, face |
+ Font face name. |
+
+
+ font_weight, weight |
+ Numeric value in 0..900 range or one of "ultralight",
+ "light", "normal" (all meaning non-bold), "bold", "ultrabold"
+ and "heavy" (all meaning bold). |
+
+
+ font_style, style |
+ Either "oblique" or "italic" (both with the same meaning)
+ or "normal". |
+
+
+ size |
+ The font size can be specified either as "smaller" or
+ "larger" relatively to the current font, as a CSS font size
+ name ("xx-small", "x-small", "small", "medium", "large",
+ "x-large" or "xx-large") or as a number giving font size in
+ 1024th parts of a point, i.e. 10240 for a 10pt font. |
+
+
+
+ This markup language is a strict subset of Pango markup (described at
+ http://library.gnome.org/devel/pango/unstable/PangoMarkupFormat.html)
+ and any tags and span attributes not documented above can't be used
+ under non-GTK platforms.
+
+ Also note that you need to escape the following special characters:
+
+
+ Special character |
+ Escape as |
+
+
+ @c & |
+ @c & or as @c && |
+
+
+ @c ' |
+ @c ' |

+
+ @c " |
+ @c " |
+
+
+ @c < |
+ @c < |
+
+
+ @c > |
+ @c > |
+
+
+
+ The non-escaped ampersand @c & characters are interpreted as
+ mnemonics as with wxControl::SetLabel.
+
+
+ @param markup
+ String containing markup for the label. It may contain markup tags
+ described above and newline characters but currently only wxGTK and
+ wxOSX support multiline labels with markup, the generic
+ implementation (also used in wxMSW) only handles single line markup
+ labels. Notice that the string must be well-formed (e.g. all tags
+ must be correctly closed) and won't be shown at all otherwise.
+ @return
+ @true if the new label was set (even if markup in it was ignored)
+ or @false if we failed to parse the markup. In this case the label
+ remains unchanged.
+
+
+ Currently wxButton supports markup in all major ports (wxMSW, wxGTK and
+ wxOSX/Cocoa) while wxStaticText supports it in wxGTK and wxOSX and its
+ generic version (which can be used under MSW if markup support is
+ required). Extending support to more controls is planned in the future.
