When I compile Wxwidgets apps on windows using g++ it’s GUI look old. After some research i found that’s called visual styles. I know i can use rc(manifest file) to disable visual styles. but i don’t know how to do that. After asking how to fix that on Chat-gpt it state that i need to add this “-DwxNO_WINDOWS_SETUP” to g++. it didn’t work.

Can anyone show me how to disable visual styles using rc(manifest file) on code below.

Hears a code Chat-gpt give me after asking another time how to disable visual theme. This didn’t work either.

#include <wx/wx.h>
#include <wx/sysopt.h>

class MyApp : public wxApp
{
public:
    virtual bool OnInit();
};

class MyFrame : public wxFrame
{
public:
    MyFrame(const wxString& title);
};

wxIMPLEMENT_APP(MyApp);

bool MyApp::OnInit()
{
    // Disable default theme for wxWidgets windows
    wxSystemOptions::SetOption("msw.disable.wxwindow.default.theme", 1);

    // Create the main application window
    MyFrame* frame = new MyFrame("Hello World");
    frame->Show(true);

    return true;
}

MyFrame::MyFrame(const wxString& title)
    : wxFrame(NULL, wxID_ANY, title)
{
    // Your frame setup code here
}

This is the command line that i used to compile Wxwidgets apps.
g++ include/src/*.cpp *.cpp -pipe -I C:wxWidgetsinclude -I C:wxWidgetslibgcc810_x64_dllmswu -L C:wxWidgetslibgcc810_x64_dll -mwindows -lwxbase32u -lwxmsw32u_core -g -o build/debug/a.exe
