C++ GUI : wxWidgets 설치

 

1. 로그인(Login) 구현하시 위해 LoginFrame을 별도로 만들어 습니다.

 

2. App.h 파일을 추가합니다.

#pragma once

#include <wx/wx.h>

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

 

3. App.cpp 파일을 추가합니다.

#include "App.h"
#include "LoginFrame.h"

wxIMPLEMENT_APP(MyApp);

bool MyApp::OnInit()
{
    LoginFrame* login = new LoginFrame();
    SetTopWindow(login);
    login->Show();
    return true;
}

 

4. LoginFrame.h 파일을 추가합니다.

#pragma once
#include <wx/wx.h>

class LoginFrame : public wxFrame
{
public:
    LoginFrame();

private:
    wxTextCtrl* m_textCtrlId;
    wxTextCtrl* m_textCtrlPw;

    void OnLogin(wxCommandEvent& event);
    bool CheckAuth(const wxString& id, const wxString& pw);
};

 

5. LoginFrame.cpp

#include "LoginFrame.h"
#include "MainFrame.h"

LoginFrame::LoginFrame()
    : wxFrame(nullptr, wxID_ANY, "Login", wxDefaultPosition, wxSize(300, 200))
{
    CentreOnScreen();

    wxPanel* panel = new wxPanel(this);

    new wxStaticText(panel, wxID_ANY, "ID", wxPoint(20, 20));
    m_textCtrlId = new wxTextCtrl(panel, wxID_ANY, "", wxPoint(80, 20), wxSize(180, 25));
 
    new wxStaticText(panel, wxID_ANY, "PW", wxPoint(20, 60));
    m_textCtrlPw = new wxTextCtrl(panel, wxID_ANY, "", wxPoint(80, 60), wxSize(180, 25), wxTE_PASSWORD);

    wxButton* btn = new wxButton(panel, wxID_ANY, "Login", wxPoint(80, 100));
    
	btn->Bind(wxEVT_BUTTON, &LoginFrame::OnLogin, this);
}

void LoginFrame::OnLogin(wxCommandEvent& event)
{
    wxString id = m_textCtrlId->GetValue();
    wxString pw = m_textCtrlPw->GetValue();

    if (CheckAuth(id, pw))
    {
        wxMessageBox("Login Success!");

        MainFrame* mainFrame = new MainFrame();
        wxTheApp->SetTopWindow(mainFrame);
        mainFrame->Show(true);

        Destroy();        
    }
    else
    {
        wxMessageBox("Login Failed!");
    }
}

bool LoginFrame::CheckAuth(const wxString& id, const wxString& pw)
{
    return (id == "admin" && pw == "1234");
}

 

6. MainFrame.h 파일을 추가합니다.

#pragma once
#include <wx/wx.h>

class MainFrame : public wxFrame
{
public:
    MainFrame();
};

 

7. MainFrame.cpp 파일을 추가합니다.

#include "MainFrame.h"

MainFrame::MainFrame()
    : wxFrame(nullptr, wxID_ANY, "Main Frame", wxDefaultPosition, wxSize(600, 400))
{
    CentreOnScreen();

    wxPanel* panel = new wxPanel(this);

    new wxStaticText(panel, wxID_ANY, "Welcome to Main System", wxPoint(20, 20));
}
