Newbie wxpython staticbitmap help please

[janama]

Hi, how do i go about having my little gui (boa) app updating
(changing) the bitmap used in a StaticBitmap automatically. In the
example below when i click the button the app check checks to see if a
file exists and if so it swaps the StaticBitmap in the gui to another
bitmap.
Can somewhone add a wx.Timer example to this to make it check
if the file exists every minute or so , instead of clicking the button
to check and update this? Or is there a better way of auto updating my
little gui apps StaticBitmap if a file exists?


Thanks for any help with this

Regards

Why won't you write it yourself using the demo ?
It's clear and well documented.

Hi, have been just trying for 5 hours with the timer demo in wx, i just
havnt clicked with how to tie it in together,

I know (think) i need the following features from the timer demo ,
where you can periodically call a function using the wx.timer

self.Bind(wx.EVT_TIMER, self.OnTest1Timer)
#---(bind to the frame ?)

self.Bind(wx.EVT_BUTTON, self.OnTest3Start, t3b1)
#---(this binds to a button, how do i bind to my application on load or
startup instead ?)

def OnTest1Timer(self, evt):
self.log.write("got EVT_TIMER event\n")
#---(dont think i need the logging?)

def OnTest3Start(self, evt):
self.t3 = NotifyTimer(self.log)
self.t3.Start(1000)
self.log.write("NotifyTimer timer started\n")
self.t3b2.Enable()

#---(the Start i guess i will work if i remap the button event to an on
load type? event?

def OnTest3Stop(self, evt):
self.t3.Stop()
self.log.write("NotifyTimer timer stoped\n")
del self.t3
self.t3b2.Disable()
#---(Guess i wont need to stop the timer, as i want it to trigger the
'refreshing' of the StaticBitmaps ?)

# When deriving from wx.Timer you must provide a Notify method
# that will be called when the timer expires.
class NotifyTimer(wx.Timer):
def __init__(self, log):
wx.Timer.__init__(self)
self.log = log

def Notify(self):
self.log.write("got NotifyTimer event\n")
#---(dont know if i need this if i dont want to use this log feature)?


Im sorry if this all seems really amatuerish, i have genuially tried
hard to get my head around it , but i get error after error in boa.
Somewhone couldnt append a timer and perhaps help to refresh the
StaticBitmaps described, with the code, in first post). I will be able
to see and learn greatly from this.

Maybe some advice on where to find lists of the methods used in
wxpython
For example it took me hours to find methods ? like

StaticBitmap.SetImage("imageName")

Is there any good lists of these methods, properties etc for wxpython
controls?

Any good wxpython ide/editors that can "intellisense" them? boa,
komodo, stani's arnt working with "intellisensing" wx for me, (maybe i
cant configure them though)

Thanks for any help with any of this

Regards

I have no time at the moment.
I'm going to try to give you an answer tomorrow morning (june 16) (if
nobody did of course).
See you

You don't need of course, it's just for demo information.

def OnTest3Start(self, evt):
self.t3 = NotifyTimer(self.log)
self.t3.Start(1000)
self.log.write("NotifyTimer timer started\n")
self.t3b2.Enable()

Boa is well done for editing, simple objects generation, also for
learning, but not for complex operation. It's not a good idea to use it
for your present need.

StaticBitmaps described, with the code, in first post). I will be able
to see and learn greatly from this.

Maybe some advice on where to find lists of the methods used in
wxpython
For example it took me hours to find methods ? like

In the help file, there is an alphabetic classes list, with (quite) all
the methods.

StaticBitmap.SetImage("imageName")

Is there any good lists of these methods, properties etc for wxpython
controls?

See before. This is the best, and also the demo (and also the sources).

Any good wxpython ide/editors that can "intellisense" them? boa,
komodo, stani's arnt working with "intellisensing" wx for me, (maybe i
cant configure them though)

The best is probably boa, because it have got a debugger, with a
separate process launched for testing.

Thanks for any help with any of this

All what you have to do is :
def __init__(self, parent):
self._init_ctrls(parent)
self.t1 = wx.Timer(self)
self.t1.Start(2000) # 2 seconds
self.Bind(wx.EVT_TIMER, self.OnTest1Timer)

def OnTest1Timer(self, evt):
if os.path.isfile('App1.py'):
i = wx.Image('image.jpg',wx.BITMAP_TYPE_JPEG)
b1 = wx.BitmapFromImage(i)
self.staticBitmap1.SetBitmap(b1)
And you can continue to use Boa as usual.
Hope you'll enjoy,
jm
Ps: tested on xp, pretty sure it works also on linux.

Thanks Jean this now makes sense, really appreciate your time and
effort mate.

def __init__(self, parent):
self._init_ctrls(parent)
self.t1 = wx.Timer(self)
self.t1.Start(2000) # 2 seconds
self.Bind(wx.EVT_TIMER, self.OnTest1Timer)

self.OnTest1Timer(self)

def OnTest1Timer(self, evt):

if os.path.isfile('images/page1.txt'):
print "ok file present"
i = wx.Image('images/pageGreen.png',wx.BITMAP_TYPE_PNG)
b1 = wx.BitmapFromImage(i)
self.staticBitmap1.SetBitmap(b1)
else:
print "ok file present"
i = wx.Image('images/pageGrey.png',wx.BITMAP_TYPE_PNG)
b1 = wx.BitmapFromImage(i)
self.staticBitmap1.SetBitmap(b1)

The above works a treat,

thanks again Jean
