Hello,

I am using latest wxWidgets master on Windows 11 using clang-20.

The default colours for wxRichTooltip when using dark theme, are not suitable for the selected dark theme.
See attached screenshot.

Can this be seen in the "Rich tooltip" dialog of the dialogs sample? I don't see this there, but it's probably because I'm testing under Windows 10 and your screenshot is from 11?

I can't make it happen with the dialogs sample. I do see that not all tooltips are behaving the same, not sure why.
For example, for the text control, the tooltip seems light while for the button it is dark.

It looks to me as if the "blue" title from the "light" tooltip was kept when rendering the dark tooltip (in my initial issue report)

This is indeed what I see too. The reason the tooltips are different is that text control has its own, native, support for rich tooltips, which we use if possible.

How exactly does your code showing the tooltip look?

This is the Show code:

void NewLLMEndpointWizard::ShowTipFor(const wxString& message, wxWindow* control)
{
    m_tooltip = std::make_unique<wxRichToolTip>(_("Failed Validation"), message);
    m_tooltip->SetTimeout(3000);
    m_tooltip->SetIcon(wxICON_WARNING);
    m_tooltip->ShowFor(control);
}

It is being called from the OnPageChanging event of the Wizard:

void NewLLMEndpointWizard::OnPageChanging(wxWizardEvent& event)
{
    event.Skip();
    if (!event.GetDirection()) {
        return;
    }

    if (event.GetPage() == m_wizardPageSettings) {
        // Check that all settings were populated.

        bool is_ok = IsValidURL(m_textCtrlBaseURL->GetValue().ToStdString(wxConvUTF8));
        if (!is_ok) {
            ShowTipFor(_("Invalid URL"), m_textCtrlBaseURL);
            event.Veto();
            event.Skip(false);
            return;
        }

        if (m_textCtrlModel->IsEmpty()) {
            ShowTipFor(_("Please choose a model"), m_textCtrlModel);
            event.Veto();
            event.Skip(false);
            return;
        }
    } else if (event.GetPage() == m_wizardPageAPI) {
        // API key is not needed for Ollama Local
        wxString provider = m_choiceProviders->GetStringSelection();
        if (provider == kProviderOllamaLocal) {
            return;
        }

        if (m_textCtrlAPIKey->IsEmpty()) {
            wxString message;
            message << _("API Key is required for provider: ") << provider;
            ShowTipFor(message, m_choiceProviders);
            event.Veto();
            event.Skip(false);
            return;
        }
    }
}

Very strange, it really looks like this should be reproducible in the sample by selecting "timeout 3d" and "warning" in the dialog and showing tooltip for the text — but it isn't.

If you could please make a minimal patch to the sample showing the problem, it would help a lot with debugging it.

Hi @vadz look at ShowFor Method and m_canUseNative at
https://github.com/wxWidgets/wxWidgets/blob/master/src/msw/richtooltip.cpp#L150
you need to handel native tooltip created by Edit_ShowBalloonTip at MSWOnNotify
