( #3333=superdoc: print w/replies, xml ) Need Help??

I have no idea which widgets have a getDC() method

Afaik, none of them do. A quick grep of the docs suggest that the following have a GetDC(): Wx::EraseEvent, Wx::HtmlWinParser, Wx::Printout. I think there are two ways of achieving what your're after (maybe more) - either use a Wx::ClientDC:

my $dc = new Wx::ClientDC($frame); $dc->DrawLine(...);

or set up a Wx::PaintEvent for your frame:

use Wx::Event 'EVT_PAINT'; EVT_PAINT($frame, \&OnPaint); sub OnPaint { my ($frame, $event) = @_; my $dc = new Wx::PaintDC($frame); $dc->DrawLine(...); }

See Wx::Perl::Throbber for an example of the latter.

The wxPython wiki has lots of useful examples. They're in Python obviously, but it's trivial to do the translation in your head.

Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
