Wx::FontDialog Problem

by T.G. Cornholio (Scribe)
on Mar 30, 2005 at 03:51 UTC ( #443335=perlquestion: print w/replies, xml ) Need Help??
T.G. Cornholio has asked for the wisdom of the Perl Monks concerning the following question:

Wise Monks, I am trying to use Wx::FontDialog on Windows XP to let the user select a font. However, I don't seem to be able to retrieve the font information from the dialog box. I have created a short demo (adapted from this one) of the problem below. The way I understand it (may or may not be correct) is as follows: The GetFontData method returns a reference to a Wx::FontData object. From this object, I should be able to get the Wx::Font that the user chose. However, I always get output as seen here:
OK button pressed, getting font info... Font Data: Wx::FontData=SCALAR(0x1c051ec) Font: 1
Shouldn't $font be a reference to Wx::Font instead of a "1"? My setup is as follows:

Windows XP
ActiveState Perl 5.6.1 build 635
Wx version 0.21 installed from here.

Any advice is most appreciated.

use Wx; package MyApp; use strict; use vars qw(@ISA); @ISA=qw(Wx::App); $| = 1; sub OnInit { my($this) = @_; my($frame) = MyFrame->new("Font Selector Demo", Wx::Point->new(50, + 50), Wx::Size->new(450, 350)); $this->SetTopWindow($frame); $frame->Show(1); 1; } package MyFrame; use strict; use vars qw(@ISA); @ISA=qw(Wx::Frame); use Wx::Event qw(EVT_MENU); use Wx qw(wxBITMAP_TYPE_ICO wxMENU_TEAROFF); sub new { my($class) = shift; my($this) = $class->SUPER::new(undef, -1, $_[0], $_[1], $_[2]); my($mfile) = Wx::Menu->new(undef, wxMENU_TEAROFF); my($ID_TEST, $ID_EXIT) = (1, 2); $mfile->Append($ID_TEST, "&Test Font Dialog\tCtrl-T", "Display a f +ont dialog"); $mfile->Append($ID_EXIT, "E&xit\tAlt-X", "Quit this program"); my($mbar) = Wx::MenuBar->new(); $mbar->Append($mfile, "&Test"); $this->SetMenuBar($mbar); EVT_MENU($this, $ID_TEST, \&OnTest); EVT_MENU($this, $ID_EXIT, \&OnQuit); $this; } sub OnQuit { my($this, $event) = @_; $this->Close(1); } use Wx qw(wxID_OK wxOK wxICON_INFORMATION wxVERSION_STRING); sub OnTest { my($this, $event) = @_; my $fontdata; my $font; my $facename; my $dialog = Wx::FontDialog->new($this); $dialog->Create($this); if ($dialog->ShowModal() == wxID_OK) { print "OK button pressed, getting font info...\n"; $fontdata = $dialog->GetFontData; print " Font Data: $fontdata\n"; $font = $fontdata->GetChosenFont(); print " Font: $font\n"; } } package main; my($app) = MyApp->new(); $app->MainLoop();

    print "Face: ", $font->GetFaceName;
    I don't know why $font stringifies to 1 (you should ask about that on wxperl-users, probably a bug), but you do have a bonafied object.

    I tried it on my machine on Windows, and it does work as PodMaster suggested: It is an object, as you can see using

    print " ref Font: " . ref($font) . "\n";

    which prints ref Font: Wx::Font on my machine.

    By the way, don't forget to use SetInitialFont() and remember the font data to set the initial font displayed to the user, or else your application will forget it's settings. E.g., do this:

    sub OnTest { my($self, $event) = @_; my $dialog = Wx::FontDialog->new($self, $self->{fontdata}); $dialog->Create($self); if ($dialog->ShowModal() == wxID_OK) { $self->{fontdata} = $dialog->GetFontData(); my $font = $self->{fontdata}->GetChosenFont(); $self->{fontdata}->SetInitialFont($font); printf("You chose %s %ipt\n", $font->GetFaceName(), $font->GetPointSize()); } else { print "No choice.\n"; } }

    Thank you both for your replies. I guess I was just thrown off that it didn't seem like it was a reference. But it's working perfectly.
