\section{\class{wxHyperlinkCtrl}}\label{wxhyperlinkctrl}
|
|
|
|
This class shows a static text element which links to an URL.
|
|
Appearance and behaviour is completely customizable. In fact, when the user
|
|
clicks on the hyperlink, a \helpref{wxHyperlinkEvent}{wxhyperlinkevent} is
|
|
sent but if that event is not handled (or it's skipped; see
|
|
\helpref{wxEvent::Skip}{wxeventskip}), then a call to
|
|
\helpref{wxLaunchDefaultBrowser}{wxlaunchdefaultbrowser} is done with the
|
|
hyperlink's URL.
|
|
|
|
Note that standard \helpref{wxWindow}{wxwindow} functions like \helpref{SetBackgroundColour}{wxwindowsetbackgroundcolour}, \helpref{SetFont}{wxwindowsetfont}, \helpref{SetCursor}{wxwindowsetcursor}, \helpref{SetLabel}{wxwindowsetlabel} can be used to customize appearance of the hyperlink.
