following character is a @e mnemonic for this control and can be used to
activate it from the keyboard (typically by using @e Alt key in
combination with it). To insert a literal ampersand character, you need
- to double it, i.e. use use "&&". If this behaviour is undesirable, use
+ to double it, i.e. use "&&". If this behaviour is undesirable, use
SetLabelText() instead.

+ Sets the controls label to a string using markup.
+
+ Simple markup supported by this function can be used to apply different
+ fonts or colours to different parts of the control label when supported.
+ If markup is not supported by the control or platform, it is simply
+ stripped and SetLabel() is used with the resulting string.
+
+ For example,
+ @code
+ wxStaticText *text;
+ ...
+ text->SetLabelMarkup("<b>&Bed</b> &mp; "
+ "<span foreground='red'>breakfast</span> "
+ "available <big>HERE</big>");
+ @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.

+ 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:
+ <TABLE>
+ <TR>
+ <TD><b>Special character</b></TD>
+ <TD><b>Escape as</b></TD>
+ </TR>
+ <TR>
+ <TD>@c &</TD>
+ <TD>@c &amp; or as @c &&</TD>
+ </TR>
+ <TR>
+ <TD>@c '</TD>
+ <TD>@c &apos;</TD>
+ </TR>
+ <TR>
+ <TD>@c "</TD>
+ <TD>@c &quot;</TD>
+ </TR>
+ <TR>
+ <TD>@c <</TD>
+ <TD>@c &lt;</TD>
+ </TR>
+ <TR>
+ <TD>@c ></TD>
+ <TD>@c &gt;</TD>
+ </TR>
+ </TABLE>
+
+ 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.
