wxPython:启动画面SplashScreen介绍

  程序启动时出现一个启动画面，先看代码：

class PaintApp(wx.App):
    def OnInit(self):
        bmp = wx.Image("P7080079.JPG").ConvertToBitmap()
        wx.SplashScreen(bmp,
                        wx.SPLASH_CENTER_ON_SCREEN | wx.SPLASH_TIMEOUT,
                        3000,
                        None,
                        -1)
        wx.Yield()
        frame = PaintFrame(None)
        frame.Show(True)
        self.SetTopWindow(frame)
        return True
    
        
if __name__ == '__main__':
    app = PaintApp()
    app.MainLoop()     

测试一下,使用一张自己前几天拍的荷花。

知识点：

原型：

wxSplashScreen(const wxBitmap& bitmap, long splashStyle, int milliseconds, wxWindow* parent, wxWindowID id, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, long style = wxSIMPLE_BORDER|wxFRAME_NO_TASKBAR|wxSTAY_ON_TOP)

splashStyle is a bitlist of some of the following:

• wxSPLASH_CENTRE_ON_PARENT
• wxSPLASH_CENTRE_ON_SCREEN
• wxSPLASH_NO_CENTRE
• wxSPLASH_TIMEOUT
• wxSPLASH_NO_TIMEOUT

milliseconds is the timeout in milliseconds.

方法：

• wxSplashScreen::OnCloseWindow
• wxSplashScreen::GetSplashStyle
• wxSplashScreen::GetSplashWindow
• wxSplashScreen::GetTimeout
