wxStyleTextCtrl::SetLexer not setting lexer Topic is solved

[PaulR]

I am wondering if this rings a bell with anybody. GetLexer returns '0' after SetLexer(3) and there is no syntax highlighting after these steps:

Code: Select all

m_stc->SetLexer(wxSTC_LEX_CPP);
m_stc->StyleSetForeground(wxSTC_C_DEFAULT, wxColour(20, 20, 200));
m_stc->StyleSetForeground(wxSTC_C_COMMENT, wxColour(150, 150, 150));
m_stc->SetKeyWords(0, 
    wxT(
        "alignas alignof and and_eq asm atomic_cancel atomic_commit "
    )
);

…

m_stc->Connect(wxEVT_STC_MODIFIED, 
    wxStyledTextEventHandler(MainWindow::onStcModified), NULL, this
);

…

void onStcModified(wxStyledTextEvent& event)
{
    m_stc->SetLexer(wxSTC_LEX_CPP);
    uint64_t start_pos = m_stc->GetEndStyled(); // <- this is always zero too
    uint64_t end_pos = m_stc->GetLineEndPosition(m_stc->LineFromPosition(m_stc->GetCurrentPos()));
    m_stc->Colourise(0, end_pos);
    auto lex = m_stc->GetLexer();
}

Using wxWidgets 3.1.2 on Windows, installed via vcpkg.

Have I missed out on a vital config option or something?

There was a problem with the CMake files that left out compiling the lexers. It was fixed a while back, but vcpkg must still be using the old CMake files. i can't think of any way to fix this after the library has been build, so if you need the lexers, you'll probably need to build the wxWidgets libraries yourself.

Ah okay that's good news I can sort it out, thanks for the reply!
