01 - 编译链接第一个wxWidgets3.0例子

1. preprocessor

#define __WXMSW__
#define WXUSINGDLL

2. vc10中设置Include dir, lib dir, dll path

VC++平台编译完的lib 和DLL都在这个目录下 C:\Programs\wxWidgets-3.0.0\lib\vc_dll

3. HelloWorld源代码

 // wxWidgets "Hello world" Program
 // For compilers that support precompilation, includes "wx/wx.h".
 #define __WXMSW__
 #define WXUSINGDLL
 #include <wx/wx.h>

 class MyApp: public wxApp
 {
 public:
 virtual bool OnInit();
 };
 class MyFrame: public wxFrame
 {
 public:
 MyFrame(const wxString& title, const wxPoint& pos, const wxSize& size);
 private:
 void OnHello(wxCommandEvent& event);
 void OnExit(wxCommandEvent& event);
 void OnAbout(wxCommandEvent& event);
 wxDECLARE_EVENT_TABLE();
 };
 enum
 {
 ID_Hello =
 };
 wxBEGIN_EVENT_TABLE(MyFrame, wxFrame)
 EVT_MENU(ID_Hello, MyFrame::OnHello)
 EVT_MENU(wxID_EXIT, MyFrame::OnExit)
 EVT_MENU(wxID_ABOUT, MyFrame::OnAbout)
 wxEND_EVENT_TABLE()
 wxIMPLEMENT_APP(MyApp);
 bool MyApp::OnInit()
 {
 MyFrame *frame = new MyFrame( "Hello World", wxPoint(, ), wxSize(, ) );
 frame->Show( true );
 return true;
 }
 MyFrame::MyFrame(const wxString& title, const wxPoint& pos, const wxSize& size)
 : wxFrame(NULL, wxID_ANY, title, pos, size)
 {
 wxMenu *menuFile = new wxMenu;
 menuFile->Append(ID_Hello, "&Hello...\tCtrl-H",
 "Help string shown in status bar for this menu item");
 menuFile->AppendSeparator();
 menuFile->Append(wxID_EXIT);
 wxMenu *menuHelp = new wxMenu;
 menuHelp->Append(wxID_ABOUT);
 wxMenuBar *menuBar = new wxMenuBar;
 menuBar->Append( menuFile, "&File" );
 menuBar->Append( menuHelp, "&Help" );
 SetMenuBar( menuBar );
 CreateStatusBar();
 SetStatusText( "Welcome to wxWidgets!" );
 }
 void MyFrame::OnExit(wxCommandEvent& event)
 {
 Close( true );
 }
 void MyFrame::OnAbout(wxCommandEvent& event)
 {
 wxMessageBox( "This is a wxWidgets' Hello world sample",
 "About Hello World", wxOK | wxICON_INFORMATION );
 }
 void MyFrame::OnHello(wxCommandEvent& event)
 {
 wxLogMessage("Hello world from wxWidgets!");
 }

第一个程序很简单，应该不会出什么错误.
