wxWidgets自定义的窗口事件--转帖

经常会碰到自定义窗口需要自己处理OnKeyDown、OnKeyUp、OnChar等事件，单有些时候接受不正常，这个时候就需要在自定义窗口中使用wxWANTS_CHARS 这个style，附上自己的例子代码：

#include <wx/wx.h>

#include <wx/splitter.h>

class MyWin: public wxWindow

{

public:

MyWin(wxWindow* parent);

virtual ~MyWin(){};

private:

void OnKeyDown(wxKeyEvent& event);

void OnKeyUp(wxKeyEvent& event);

void OnChar(wxKeyEvent& event);

private:

DECLARE_EVENT_TABLE()

};

class MyFrame : public wxFrame

{

public:

virtual ~MyFrame(void);

private:

void OnClose(wxCloseEvent &event);

void OnQuit(wxCommandEvent& WXUNUSED(event));

private:

void CreateGUIControls(void);

private:

DECLARE_EVENT_TABLE()

};

class MyApp : public wxApp

{

private:

MyFrame *m_pMainFrame;

public:

MyApp(void);

virtual ~MyApp(void);

protected:

virtual bool OnInit();

};

IMPLEMENT_APP(MyApp)

MyApp::MyApp(void)

: m_pMainFrame(NULL)

{

}

MyApp::~MyApp(void)

{

}

bool MyApp::OnInit()

{

wxInitAllImageHandlers();

m_pMainFrame = new MyFrame(NULL, wxID_ANY, wxT("MyApp"), wxDefaultPosition, wxDefaultSize);

m_pMainFrame->Centre();

m_pMainFrame->Show(TRUE);

SetTopWindow(m_pMainFrame);

return TRUE;

}

BEGIN_EVENT_TABLE(MyFrame, wxFrame)

EVT_CLOSE(MyFrame::OnClose)

EVT_MENU(wxID_CLOSE, MyFrame::OnQuit)

END_EVENT_TABLE()

MyFrame::MyFrame(wxWindow *pParent, wxWindowID id, const wxString& title, const wxPoint& pos, const wxSize& size, long style, const wxString& name)

: wxFrame(pParent, id, title, pos, size, style, name)

{

CreateGUIControls();

}

MyFrame::~MyFrame(void)

{

}

void MyFrame::CreateGUIControls(void)

{

wxMenu *menuFile = new wxMenu;

menuFile->Append( wxID_CLOSE, wxT("E&xit") );

wxMenu *menuHelp = new wxMenu;

menuHelp->Append( wxID_ABOUT, wxT("&About...") );

wxMenuBar *menuBar = new wxMenuBar;

menuBar->Append( menuFile, wxT("&File") );

menuBar->Append( menuHelp, wxT("&Help") );

SetMenuBar( menuBar );

CreateStatusBar();

SetStatusText(wxT("Ready"));

SetMinSize( wxSize( 800, 600 ) );

wxSplitterWindow* m_pSashSplitter = new wxSplitterWindow(this, wxID_ANY, wxDefaultPosition, wxDefaultSize, wxSP_3D | wxCLIP_CHILDREN | wxWANTS_CHARS );

MyWin* pWin = new MyWin(m_pSashSplitter);

pWin->SetBackgroundColour(*wxGREEN);

wxPanel* panel = new wxPanel( m_pSashSplitter);

m_pSashSplitter->SplitVertically( pWin,panel,565);

}

void MyFrame::OnClose(wxCloseEvent& event)

{

event.Skip();

}

void MyFrame::OnQuit(wxCommandEvent& WXUNUSED(event))

{

Close();

}

BEGIN_EVENT_TABLE(MyWin, wxWindow)

EVT_KEY_UP( MyWin::OnKeyUp )

EVT_KEY_DOWN( MyWin::OnKeyDown )

EVT_CHAR( MyWin::OnChar )

END_EVENT_TABLE()

MyWin::MyWin(wxWindow* parent)

: wxWindow(parent, wxID_ANY, wxDefaultPosition, wxDefaultSize,wxWANTS_CHARS )

{

}

void MyWin::OnChar(wxKeyEvent& event)

{

wxLogDebug( wxString::Format(wxT("bbbb %d"), event.GetKeyCode()) );

event.Skip();

}

void MyWin::OnKeyDown(wxKeyEvent& event)

{

switch(event.GetKeyCode())

{

case WXK_RIGHT:

wxLogDebug( wxT("right down") );

break;

case WXK_LEFT:

wxLogDebug( wxT("left down") );

break;

case WXK_UP:

wxLogDebug( wxT("up down") );

break;

case WXK_DOWN:

wxLogDebug( wxT("down down") );

break;

default:

break;

}

event.Skip();

}

void MyWin::OnKeyUp(wxKeyEvent& event)

{

switch(event.GetKeyCode())

{

case WXK_RIGHT:

wxLogDebug( wxT("right up") );

break;

case WXK_LEFT:

wxLogDebug( wxT("left up") );

break;

case WXK_UP:

wxLogDebug( wxT("up up") );

break;

case WXK_DOWN:

wxLogDebug( wxT("down up") );

break;

default:

break;

}

event.Skip();

}
