  10     @class wxCommandLinkButton
  11
  12     Objects of this class are similar in appearance to the normal wxButtons but
  13     are similar to the links in a web page in functionality.
  14
  15     Pressing such button usually results in switching to another window of the
  16     program and so they can be used as a replacement for the "Next" button in a
  17     multi-page dialog (such as wxWizard), for example.
  18
  19     Their advantage compared to the ordinary wxButtons is that they emphasize
  20     the action of switching the window and also that they allow to give more
  21     detailed explanation to the user because, in addition to the short button
  22     label, they also show a longer description string.
  23
  24     The short, title-like, part of the label is called the <em>main label</em>
  25     and the longer description is the <em>note</em>. Both of them can be set
  26     and queried independently using wxCommandLinkButton-specific methods such
  27     as SetMainLabel() or GetNote() or also via SetLabel() and GetLabel()
  28     methods inherited from wxButton. When using the latter, the main label and
  29     the note are concatenated into a single string using a new line character
  30     between them (notice that the note part can have more new lines in it).
  31
  32     wxCommandLinkButton generates the same event as wxButton but doesn't
  33     support any of wxButton-specific styles nor adds any new styles of its own.
  34
  35     Currently this class uses native implementation under Windows Vista and
  36     later versions and a generic implementation for the other platforms and
  37     earlier Windows versions.
