+The MakeActiveXClass function dynamically builds a new Class on the fly, that has the +same signature and semantics as wxWindow. This means that when you call the function +you get back a new class that you can use just like wxWindow, (set the size and position, +use in a sizer, etc.) except its contents will be the COM control. +
+This demo embeds the Adobe Acrobat Reader, and gives you some buttons for opening a PDF +file, changing pages, etc. that show how to call methods on the COM object. If you don't +have Acrobat Reader 4.0 installed it won't work. + +""" + +from wxPython.wx import * + +if wxPlatform == '__WXMSW__': + from wxPython.lib.activexwrapper import MakeActiveXClass + import win32com.client.gencache + + try: + acrobat = win32com.client.gencache.EnsureModule('{CA8A9783-280D-11CF-A24D-444553540000}', 0x0, 1, 3) + except: + raise ImportError("Can't load PDF.OCX, install Acrobat 4.0") + + + +#---------------------------------------------------------------------- + +class TestPanel(wxPanel): + def __init__(self, parent): + wxPanel.__init__(self, parent, -1) + self.pdf = None + + sizer = wxBoxSizer(wxVERTICAL) + btnSizer = wxBoxSizer(wxHORIZONTAL) + + # this function creates a new class that can be used as + # a wxWindow, but contains the given ActiveX control. + ActiveXWrapper = MakeActiveXClass(acrobat.Pdf) + + # create an instance of the new class + self.pdf = ActiveXWrapper( self, -1, style=wxSUNKEN_BORDER) + + sizer.Add(self.pdf, 1, wxEXPAND) + + btn = wxButton(self, wxNewId(), "Open PDF File") + EVT_BUTTON(self, btn.GetId(), self.OnOpenButton) + btnSizer.Add(btn, 1, wxEXPAND|wxALL, 5) + + btn = wxButton(self, wxNewId(), "<-- Previous Page") + EVT_BUTTON(self, btn.GetId(), self.OnPrevPageButton) + btnSizer.Add(btn, 1, wxEXPAND|wxALL, 5) + + btn = wxButton(self, wxNewId(), "Next Page -->") + EVT_BUTTON(self, btn.GetId(), self.OnNextPageButton) + btnSizer.Add(btn, 1, wxEXPAND|wxALL, 5) + + + btnSizer.Add(50, -1, 2, wxEXPAND) + sizer.Add(btnSizer, 0, wxEXPAND) + + self.SetSizer(sizer) + self.SetAutoLayout(true) + + def __del__(self): + if self.pdf: + self.pdf.Cleanup() + self.pdf = None + + + + def OnOpenButton(self, event): + dlg = wxFileDialog(self, wildcard="*.pdf") + if dlg.ShowModal() == wxID_OK: + wxBeginBusyCursor() + self.pdf.LoadFile(dlg.GetPath()) + wxEndBusyCursor() + + dlg.Destroy() + + + def OnPrevPageButton(self, event): + self.pdf.gotoPreviousPage() + + + def OnNextPageButton(self, event): + self.pdf.gotoNextPage() + + + +#---------------------------------------------------------------------- + +def runTest(frame, nb, log): + if wxPlatform == '__WXMSW__': + win = TestPanel(nb) + return win + else: + dlg = wxMessageDialog(frame, 'This demo only works on MSW.', + 'Sorry', wxOK | wxICON_INFORMATION) + dlg.ShowModal() + dlg.Destroy() + + +overview = __doc__ + +#---------------------------------------------------------------------- + + +if __name__ == '__main__': + class TestFrame(wxFrame): + def __init__(self): + wxFrame.__init__(self, None, -1, "ActiveX test -- Acrobat", size=(640, 480), + style=wxDEFAULT_FRAME_STYLE|wxNO_FULL_REPAINT_ON_RESIZE) + self.tp = TestPanel(self, sys.stdout) + EVT_CLOSE(self, self.OnCloseWindow) + + def OnCloseWindow(self, event): + self.tp.pdf.Cleanup() + self.Destroy() + + + app = wxPySimpleApp() + frame = TestFrame() + frame.Show(true) + app.MainLoop() + + +
