一、wxMenuBar

1、创建一个菜单栏，代码如下：

wxMenuBar * m_menubar1 = new wxMenuBar(0);wxMenu *m_menu1 = new wxMenu();wxMenuItem* m_menuItem1, m_menuItem2, m_menuItem3;m_menuItem1 = new wxMenuItem(m_menu1, wxID_ANY, wxString(wxT("MyMenuItem")), wxEmptyString, wxITEM_NORMAL);m_menuItem2 = new wxMenuItem(m_menu1, wxID_ANY, wxString(wxT("MyMenuItem")), wxEmptyString, wxITEM_NORMAL);m_menuItem3 = new wxMenuItem(m_menu1, wxID_ANY, wxString(wxT("MyMenuItem")), wxEmptyString, wxITEM_NORMAL);m_menu1->Append(m_menuItem1);m_menu1->Append(m_menuItem2);m_menu1->Append(m_menuItem3);m_menubar1->Append(m_menu1, wxT("MyMenu"));this->SetMenuBar(m_menubar1);

2、右键弹出菜单

wxMenu * menu = new wxMenu();menu->Append(wxID_OPEN, wxT("&Open"));menu->AppendSeparator();menu->Append(wxID_EDIT, wxT("&Edit"));PopupMenu(menu);

3、响应的事件表

EVT_MENU

二、wxToolBar

1、创建一个工具栏，代码如下：

wxToolBar * toolBar = new wxToolBar(frame, wxID_ANY,wxDefaultPosition,wxDefaultSize,wxTB_HORIZONTAL|wxNO_BORDER);wxBitmap bmpOpen(wxImage(wxT("1.png")));wxBitmap bmpSave(wxImage(wxT("2.png")));toolBar->AddTool(wxID_OPEN, bmpOpen, wxT("Open"));toolBar->AddTool(wxID_SAVE, bmpSave, wxT("Save"));toolBar->AddSeparator();wxComboBox * comboBox = new wxComboBox(toolBar, ID_COMBOBOX);toolBar->AddControl(comboBox);toolBar->Realize();this->SetToolBar(toolBar);

三、wxStatusBar

1、创建一个状态栏，代码如下：

wxStatusBar * m_statusBar = new wxStatusBar(this,wxID_ANY,wxST_SIZEGRIP);this->SetStatusBar(m_statusBar);int widths[] = {120,120,-1};m_statusBar->SetFieldsCount(WXSIZEOF(widths),widths);m_statusBar->SetStatusText(wxT("status text"), 0);m_statusBar->SetStatusText(wxT("2017-11-25"), 1);// 在状态栏的第三个栏中添加进度条wxRect rc;m_statusBar->GetFieldRect(2,rc);wxGauge * gauge = new wxGauge(m_statusBar,ID_GAUGE,200, wxPoint(rc.x,rc.y),wxSize(rc.width,rc.height),wxGA_HORIZONTAL);gauge->SetValue(100);gauge->Show(true);// 在OnSize中重新设置进度条的宽高wxRect rc;m_statusBar->GetFieldRect(2, rc);gauge->SetSize(wxSize(rc.width, rc.height));
