ImageDialog - PythonYou are probably already familiar with a few dialogs that can be used in your wxPython applications. Of course, wxPython contains many more dialogs, ranging in complexity from very simple to pretty advanced and covering a variety of topics, from text selection to color selection. In this article, we'll take a look at more of wxPython's dialogs – what they are for and how they are placed in an application.

The ImageDialog is a very nice dialog. It displays the images in a given directory. It's very simple to use: from wxPython.wx import * # Import the required module from wxPython.lib import imagebrowser application = wxPySimpleApp() # Create the dialog dialog = imagebrowser.ImageDialog ( None ) # Show the dialog dialog.ShowModal() # Destroy the dialog dialog.Destroy() Of course, we'll need to retrieve the file name of the image that the user specifies. This is easily done: from wxPython.wx import * from wxPython.lib import imagebrowser application = wxPySimpleApp() dialog = imagebrowser.ImageDialog ( None ) # Display the file name if the user selected one if dialog.ShowModal() == wxID_OK: print 'You picked:', dialog.GetFile() # Otherwise, yell and scream at the user for cancelling else: print 'You did not select an image!' dialog.Destroy() If we need to set a directory other than the current directory, it's possible to do so by passing a second argument: from wxPython.wx import * from wxPython.lib import imagebrowser application = wxPySimpleApp() # Specify a directory dialog = imagebrowser.ImageDialog ( None, 'C:\' ) if dialog.ShowModal() == wxID_OK: print 'You picked:', dialog.GetFile() else: print 'You did not select an image!' dialog.Destroy()
