[WxPython] Adding functionality to GUI buttons

[onizuka1]

Hi all,

I have used some forum browsing and the WxDemo to create my desired GUI and struggling to find some good reference material to add functionality to my design.

This GUI will ideally pull / send information to other programs (in python and/or c) in the future but for now am at least just looking to make the program/all the buttons stable.

I saw that the demos used some sort of self.log to record button actions and was maybe thinking of having a log just record the actions of all the buttons..I've fiddled around with it but to no avail.

Future things I'm looking to do:

How I would go about loading an xml file with the browse button to eventually have the program send the file / pull data from it.

Have the database dropdown read a file to populate the list of available databases

Have one box populated from another (i.e. reading dropdown populated from database selected, or the 'populated from xml' box pull a value from one of the .xml files)

Check boxes choose whether to reprocess just file 1, file 2, or both with the start button

Have the Quit button....quit.

Any input / suggestions appreciated,

Thank you.

This site has lots of good resources :)

I have used for my quit button, although only the program closes...the stdout window stays open for some reason.

#Quit Button

        b = wx.Button(self.panel, 10, "Quit", (200, 300))
        self.Bind(wx.EVT_BUTTON, self.OnClick, b)
        b.SetDefault()
        b.SetSize(b.GetBestSize())

.
.
.

def OnQuitButton(self, evt):
        # event handler for the Quit button click or Exit menu item
        print "See you later alligator! (goes to stdout window)"
        wx.Sleep(1)    # 1 second to look at message
        self.Close()
