Codeblocks + Widgets 创建窗口代码分析

整理了一下在linux下，codeblocks中用widgets来创建窗口的大致步骤，直接看图片。

1.wx01Main.cpp

/**************************************************************** Name:      wx01Main.cpp* Purpose:   Code for Application Frame* Author:    Gary (garyao@126.com)* Created:   2022-07-30* Copyright: Gary ()* License:**************************************************************/
//预编译
#ifdef WX_PRECOMP
#include "wx_pch.h"
#endif#ifdef __BORLANDC__
#pragma hdrstop
#endif //__BORLANDC__#include "wx01Main.h"//helper functions
enum wxbuildinfoformat {short_f, long_f };wxString wxbuildinfo(wxbuildinfoformat format)
{wxString wxbuild(wxVERSION_STRING);if (format == long_f ){
#if defined(__WXMSW__)wxbuild << _T("-Windows");
#elif defined(__WXMAC__)wxbuild << _T("-Mac");
#elif defined(__UNIX__)wxbuild << _T("-Linux");
#endif#if wxUSE_UNICODEwxbuild << _T("-Unicode build");
#elsewxbuild << _T("-ANSI build");
#endif // wxUSE_UNICODE}return wxbuild;
}wx01Dialog::wx01Dialog(wxDialog *dlg): GUIDialog(dlg)
{
}wx01Dialog::~wx01Dialog()
{
}
//8. 绑定的事件
void wx01Dialog::OnClose(wxCloseEvent &event)
{Destroy();
}void wx01Dialog::OnQuit(wxCommandEvent &event)
{Destroy();
}void wx01Dialog::OnAbout(wxCommandEvent &event)
{wxString msg = wxbuildinfo(long_f);wxMessageBox(msg, _("Welcome to..."));
}

2. wxMain.h

/**************************************************************** Name:      wx01Main.h* Purpose:   Defines Application Frame* Author:    Gary (garyao@126.com)* Created:   2022-07-30* Copyright: Gary ()* License:**************************************************************/#ifndef WX01MAIN_H
#define WX01MAIN_H#include "wx01App.h"#include "GUIDialog.h"class wx01Dialog: public GUIDialog
{public:wx01Dialog(wxDialog *dlg);~wx01Dialog();private://7. 虚拟事件，在主程序里重写virtual void OnClose(wxCloseEvent& event);virtual void OnQuit(wxCommandEvent& event);virtual void OnAbout(wxCommandEvent& event);
};
#endif // WX01MAIN_H

3. wx01App.h

/**************************************************************** Name:      wx01App.h* Purpose:   Defines Application Class* Author:    Gary (garyao@126.com)* Created:   2022-07-30* Copyright: Gary ()* License:**************************************************************/#ifndef WX01APP_H
#define WX01APP_H
//1.首先，需要继承wxApp
#include <wx/app.h>class wx01App : public wxApp
{public:virtual bool OnInit();
};#endif // WX01APP_H

4. wx01App.cpp

/**************************************************************** Name:      wx01App.cpp* Purpose:   Code for Application Class* Author:    Gary (garyao@126.com)* Created:   2022-07-30* Copyright: Gary ()* License:**************************************************************/#ifdef WX_PRECOMP
#include "wx_pch.h"
#endif#ifdef __BORLANDC__
#pragma hdrstop
#endif //__BORLANDC__#include "wx01App.h"
#include "wx01Main.h"
//3. 主函数表明程序的执行
IMPLEMENT_APP(wx01App);
//4. 程序初始化
bool wx01App::OnInit()
{wx01Dialog* dlg = new wx01Dialog(0L);dlg->Show();return true;
}

5. GUIDialog.h

///
// C++ code generated with wxFormBuilder (version Feb 17 2007)
// http://www.wxformbuilder.org/
//
// PLEASE DO "NOT" EDIT THIS FILE!
///#ifndef __GUIDialog__
#define __GUIDialog__// Define WX_GCH in order to support precompiled headers with GCC compiler.
// You have to create the header "wx_pch.h" and include all files needed
// for compile your gui inside it.
// Then, compile it and place the file "wx_pch.h.gch" into the same
// directory that "wx_pch.h".
#ifdef WX_GCH
#include <wx_pch.h>
#else
#include <wx/wx.h>
#endif#include <wx/button.h>
#include <wx/statline.h>//2.其次，需要一个继承与wxDialog或wxFrame的类
//////
/// Class GUIDialog
///
class GUIDialog : public wxDialog
{DECLARE_EVENT_TABLE()private://6. 事件绑定// Private event handlersvoid _wxFB_OnClose( wxCloseEvent& event ){ OnClose( event ); }void _wxFB_OnAbout( wxCommandEvent& event ){ OnAbout( event ); }void _wxFB_OnQuit( wxCommandEvent& event ){ OnQuit( event ); }protected:enum{idBtnAbout = 1000,idBtnQuit,};wxStaticText* m_staticText1;wxButton* BtnAbout;wxStaticLine* m_staticline1;wxButton* BtnQuit;// Virtual event handlers, overide them in your derived classvirtual void OnClose( wxCloseEvent& event ){ event.Skip(); }virtual void OnAbout( wxCommandEvent& event ){ event.Skip(); }virtual void OnQuit( wxCommandEvent& event ){ event.Skip(); }public:GUIDialog( wxWindow* parent, int id = wxID_ANY, wxString title = wxT("wxWidgets Application Template"), wxPoint pos = wxDefaultPosition, wxSize size = wxDefaultSize, int style = wxDEFAULT_DIALOG_STYLE );};#endif //__GUIDialog__

6. GUIDialog.cpp

///
// C++ code generated with wxFormBuilder (version Feb 17 2007)
// http://www.wxformbuilder.org/
//
// PLEASE DO "NOT" EDIT THIS FILE!
///#include "wx/wxprec.h"#ifdef __BORLANDC__
#pragma hdrstop
#endif //__BORLANDC__#ifndef WX_PRECOMP
#include <wx/wx.h>
#endif //WX_PRECOMP#include "GUIDialog.h"///
BEGIN_EVENT_TABLE( GUIDialog, wxDialog )EVT_CLOSE( GUIDialog::_wxFB_OnClose )EVT_BUTTON( idBtnAbout, GUIDialog::_wxFB_OnAbout )EVT_BUTTON( idBtnQuit, GUIDialog::_wxFB_OnQuit )
END_EVENT_TABLE()
//5. 构建窗口
GUIDialog::GUIDialog( wxWindow* parent, int id, wxString title, wxPoint pos, wxSize size, int style ) : wxDialog( parent, id, title, pos, size, style )
{this->SetSizeHints( wxDefaultSize, wxDefaultSize );wxBoxSizer* bSizer1;bSizer1 = new wxBoxSizer( wxHORIZONTAL );m_staticText1 = new wxStaticText( this, wxID_ANY, wxT("Welcome To\nwxWidgets"), wxDefaultPosition, wxDefaultSize, 0 );m_staticText1->SetFont( wxFont( 20, 74, 90, 90, false, wxT("Arial") ) );bSizer1->Add( m_staticText1, 0, wxALL|wxEXPAND, 5 );wxBoxSizer* bSizer2;bSizer2 = new wxBoxSizer( wxVERTICAL );BtnAbout = new wxButton( this, idBtnAbout, wxT("&About"), wxDefaultPosition, wxDefaultSize, 0 );bSizer2->Add( BtnAbout, 0, wxALL, 5 );m_staticline1 = new wxStaticLine( this, wxID_ANY, wxDefaultPosition, wxDefaultSize, wxLI_HORIZONTAL );bSizer2->Add( m_staticline1, 0, wxALL|wxEXPAND, 5 );BtnQuit = new wxButton( this, idBtnQuit, wxT("&Quit"), wxDefaultPosition, wxDefaultSize, 0 );bSizer2->Add( BtnQuit, 0, wxALL, 5 );bSizer1->Add( bSizer2, 1, wxEXPAND, 5 );this->SetSizer( bSizer1 );this->Layout();bSizer1->Fit( this );
}

7. 最后还有一个文件：
