how to implement propertyPage using wxPyhton?
Hi, gurus, I would like to implement something like propertyPage (VC++ term) Ie. There are a few tabs in the top, clicking any tab will display a different panel. I searched on the Internet, couldn’t get any clue. Thanks in advance. James -- http://mail.python.org/mailman/listinfo/python-list
use staticBitmap to show image with raw data?
Hi,
We have a HAMAMATSU
camera, and we want to display the real-time image (captured every 0.2s+) on
the screen. The captured image from camera is raw data, If saved to PNG file
via Image (PIL), and open with wx.Image(“*.png”), the image can be
shown on the wx.staticBitmap area.
However, the problem is the speed, the capturing takes some
time(nothing we can do), the saving takes more time, the total speed is
not acceptable completely.
There must be a way to show the raw image on screen directly
without saving to file, any idea would be appreciated!
I tried:
using raw data from Image (Image.fromstring('I', datasize,
newbuftemp, 'raw', 'I;16')), then convert it to wx.Image by using PILToWX,
which downloaded from internet, all pixels are 255!
Regards,
James

python's performance
Hi, I used python and PIL to capture image from a digital camera, It seems like it took more than 1 second to capture a 1280x1024 image, however, the demo capturing application from the company (coded by VB) took only .2s or less for one image with the same size. Don't know why python and PIL is so slow, any idea to improve the performance? Thanks a lot! James -- http://mail.python.org/mailman/listinfo/python-list
return struct in ctypes
hi,
I need to use ctypes to call the API function
like
fun1(&list,
listLen) //here
list is struct { long id; long type; long
isOpen;} ListItem;
so I define
class LIST_ITEM(Structure): _fields_
= [("Id",
c_ulong),
("Type",c_ulong ),
("isOpen",
c_ulong),
]
list=LIST_ITEM()
listLen=c_ulong(1)
thedriver.fun1(byref(list),listLen)
doesn't work, here the list is input param, not
return info.
if use
list=c_char_p()
thedriver.fun1(byref(list),listLen)
how can I convert the list to LIST_ITEM?
another Q is :
how to use ctypes to implement this:
struct1
mySettings;
// here struct1 {long size;
long params[32];} mySettings.size =
sizeof(mySettings);
Where can get ctypes good samples? the samples with the
package seems very simple. and the ctypes tutorial doesn't handle
these cases either.
Thanks in advance

PIL Image can't open png file with "I"?
Hi,
I have png file with mode "I", 16 bit,
And I tried to open it with im=Image.open("output.png"), im.show()
I got all white image.
Don't why?
Can Image only support 'RGB' or 'RGBA' png files?
Thanks

create user message for wxPython
Hi, There are 2 wxPython application, A and B and need to exchange msg. Sending WM_CLOSE, wxEVT_MOUSEWHEEL to B is OK, and sending user message like 1225 from A to B is also OK. But B didn't catch this message, note, B is running before A sends msg and can receive "WM_CLOSE". Do I have to make my own msg loop by using win32api, win32gui? I used win32gui to post Message to other windows. Using wx.Frame: wx.EVT_START_MSG= 1225 EVT_START_MSG_EVENT= wx.PyEventBinder(wx.EVT_START_MSG, 0) EVT_START_MSG_EVENT(self, self.OnStart) Or Self.Bind(EVT_START_MSG_EVENT,self.OnStart) def OnStart(self, event): print 'got start message' Thanks a lot in advance!

findwindow by its class name
Hi,
For the simple code:
from wxPython.wx import *
class MyApp(wxApp):
def OnInit(self):
frame = wxFrame(NULL, -1, "Hello App")
frame.Show(true)
self.SetTopWindow(frame)
return true
app = MyApp(0)
app.MainLoop()
Is there any way to know this windows' class name? I need to find it by
win32gui.FindWindow(classname,None) and send msg from another
application, but not using its title "Hello App".
MyApp is not the classname, for it couldn't be found by
FindWindow("MyApp",None).
Thanks a lot in advance!

RE: [python-win32] findwindow by its class name
Thanks a lot! Yes, GetHandle() can return 'wxWindowClassNR', which is nice, but all wxPython apps return wxWindowClassNR as well, so when I Post Message, it goes to itself.

You had to make me do it, didn't you? :-) wxPython windows expose their HWND via the GetHandle() method. So you can get the frame's class name as win32gui.GetClassName(frame.GetHandle()) FWIW, I get a constant value of "wxWindowClassNR".

simulate DoEvents by python/wxpython
Hi, all gurus,
I need to simulate DoEvents in VB by
python/wxPython,
My application needs to capture live image
in a loop until one specific button pressed
Multi-thread is also not very good
solution, for there are big number of data to exchange between the two threads.
Win32gui doesn’t have PeekMessage.
Or translate the folllowinf codes to
python?
DoEvents()
{
MSG msg;
while ( ::PeekMessage( &msg, NULL, 0, 0, PM_NOREMOVE ) )
{
if ( !PumpMessage( ) )
{
::PostQuitMessage( 1 );
return FALSE;
}
}
// let MFC do its idle processing
LONG lIdle = 0;
while ( OnIdle(lIdle++ ) )
;
return TRUE;
}
}

Build 205 of win32gui does have PeekMessage etc so you can now write the
message loop in Python should the need arise - however, the various
"PumpMessages" and "PumpWaitingMessages" functions do the same thing,
but
are implemented in C. There are versions of these functions in win32gui
and
win32ui. win32ui is the MFC wrapper, and its version does do it the
"MFC
way", as opposed to the vanilla Windows way that win32gui exposes. Your
code below looks like it is MFC based, so the win32ui versions may work
better for you (eg, work correctly with the MFC idle processing). If
you do
truly only need VB DoEvents style processing (which is not MFC aware),
win32gui.Pump(Waiting)Messages should be fine though.

the tag are:
256=(640,)

259=(1,)
262=(1,)
273=(110,)

296=(1,)
266=(1,)
339=(1,)
282=((1073741824, 1073741824),)

wxImage can't read tif file? (WxPython)
Hi, all gurus,
I am working on a small project, which needs to display 16 bit tiff image on
screen directly, I use wxStaticBitmap to do that, and I can show png and jpg
file on the screen without any problem. (converting from tiff to png first
is not option though). However, when I try to read tiff file, nothing
there,(the program is running without error) of course, the tiff is OK, I
can open it with IrFanView. where output.tif is about 640K, a little larger
than output.png(450K), the document says wxImage can open tif!
OR is there other way to show 16 bit tiff on windows with wxPython?
Another thing: how can I call the static methods like wxImage::FindHandler,
it always complains no matter what I use "image.FindHandler() or
wxImage.FindHandler()"
Any help will be apprecaited greatly!!!
James
the codes:
#image=wx.Image('output.png',wxBITMAP_TYPE_PNG) #Can see,
image=wx.Image('output.tif',wxBITMAP_TYPE_TIF) #can't see, still black as
the empty bitmap
bmp = image.ConvertToBitmap()
bmp.SetHeight(self.bmpHeight)
bmp.SetWidth(self.bmpWidth)
self.staticBitmap1.SetBitmap(bmp) #staticBitmap1 already defined/created
before
