I was hoping that you would look at and extract the mouse over code, not run the application.
I did explain that it was older code, but failed to mention that you probably wouldn't be able to
run it. Never the less, the event code for hovering should (I have not verified) be the same in phoenix.

I converted the old program, this will run in phoenix:

RE: moving from tkinter to wxpython - Barrowman - Feb-22-2018
Thanks very much. When I get time later I will see how I can adapt it to do what I want.
RE: moving from tkinter to wxpython - Larz60+ - Feb-22-2018
you need to pull out the parts related to:
self.Bind(wx.EVT_ENTER_WINDOW, self.OnEnter) self.Bind(wx.EVT_LEAVE_WINDOW, self.OnLeave)
Quote:When I get time later I will see how I can adapt it to do what I want.Isn't this what you were seeking?
RE: moving from tkinter to wxpython - Barrowman - Feb-22-2018
I really appreciate all the help. I think I have a long way to go before I can be anywhere as confident I know as much about the way wxpython works as I do tkinter ( and that isn't much.)
Here is a bit of the script I have so far.
class MouseEventFrame(wx.Frame):
def __init__(self, parent, id):
wx.Frame.__init__(self, parent, id, 'Frame and Button', size=(1210, 400))
self.panel = wx.Panel(self)
row = 0
column = 0
for x in range(1,67):
txt = books[x]
myname = txt[0:-3]
while (len(myname) < 15):
myname = " " + myname
while (len(myname) < 20):
myname += " "
self.btn = 'butt' + str(x)
btn = wx.Button(self.panel, -1, myname, pos=(column, row ) )
self.Bind(wx.EVT_BUTTON, self.OnClick,btn)
self.Bind(wx.EVT_ENTER_WINDOW, self.OnEnterWindow,btn)
column += 120
if column == 1200:
column = 0
row += 55
def OnClick(self, event):
obj = event.GetEventObject()
print("You clicked %s"%obj.GetLabel())
event.Skip()
def OnEnterWindow(self, event,myname):
obj = event.GetEventObject()
print("Success at last!%s"%obj.GetLabel())
print("Success at last! ",btn[-3:])
event.Skip()
app = wx.App()
frame = MouseEventFrame(parent=None, id=-1)
frame.Show()
app.MainLoop()The OnClick event works but the OnEnterWindow does nothing.I get no errors but no output appears.
RE: moving from tkinter to wxpython - Larz60+ - Feb-22-2018
try changing:
self.Bind(wx.EVT_BUTTON, self.OnClick,btn)
self.Bind(wx.EVT_ENTER_WINDOW, self.OnEnterWindow,btn)To: btn.Bind(wx.EVT_BUTTON, self.OnClick,btn)
btn.Bind(wx.EVT_ENTER_WINDOW, self.OnEnterWindow,btn)
RE: moving from tkinter to wxpython - Barrowman - Feb-23-2018
Thanks Larz60+ that fixed it. I am puzzled as to why the original partially worked.
Out of curiosity I swapped the order of the binds in thatoriginal script thinking it might make the other one work instead but it was still the OnClick which did.
Ah well thanks again.
RE: moving from tkinter to wxpython - Larz60+ - Feb-23-2018
The order of the binds is unimportant, as they are not acted upon until triggered by the event.
RE: moving from tkinter to wxpython - Barrowman - Feb-26-2018
Okay I have now got a little further and just to test it's working it plays a note as the mouse pointer enters a button.
Here is my code so far.

app.MainLoop()Obviously I want it to say the word which is on the button but when the button is clicked I want it to display a different set of buttons from 1 to the number of chapters in each book. Which it extracts from the right 3 characters in the books list.As I am just starting with wxpython I am expecting a steep learning curve.At present I am unsure where to go with it. I guess I could just use a sizer to add 66 panels with the appropriate number of buttons on them or use one panel, clear what's on it then replace them with the correct number. I don't know how to do either right now and don't relish the though of adding 66 panels manually.
However I don't know if it can be done in a loop or if the other option is viable. Any suggestions please?
