Re: [Pythoncard-users] Projects and portability

[Bernie H. <ber...@ut...>]

Hi Lance et al,=20

Your project sounds interesting and appears to be useful. Its a clear itch
worth scratching. =20

But I have to =8Cpoll the audience=B9 on this one (particularly in reference to
portability). I have a couple of applications that I use on windows and mac=
.
The wxWidgets are not the same size on both platforms, and no doubt they ar=
e
sized slightly differently on linux (gnome / kde) as well. This is okay if =
I
have lots of space to play with, but one of the apps was a data entry
application where I had to fit a LOT on one page. So basically, I ended up
making a different resource file for windows or mac.

This leads to 2 things:
1. how difficult is it to specify a different resource file (i.e. Does the
resource file always have to be fileName.rsrc.py where fileName.py is the
script).=20
2. Are there any general guidelines as to sizing? e.g. If you have enough
space horizontally for a mac, you should be fine for windows (or vice
versa).=20

I mean the app is portable in terms of function, but for me its still tied
to the OS because of layout issues.

Take care,
BERNiE

Re: [Pythoncard-users] What Project is a good one to start on?

[Lance H. <lh...@ha...>]

Hi Alex,

This is how the original app works. You enter all the server names and 
ipaddress for every Novell server on your network.
then you click the generate button and it creates a webpage that you 
can  host anywhere. ( I add it to my desktop ) This page show the latest 
status of the servers with traffic lights that are linked to the servers 
web management interface.

What the old app could not do was
1. run on anything but windows ( I use Linux and Mac) written in VB
2. import old pages to make changes (you had to recreate the page every 
time or edit the html)
3. allow automatic upload to a Intranet. (we have junior types that 
monitor the systems and let us know when things go wrong)

These are the three things that prompted me to start looking for a 
language that I could use to improve it. I tried PHP-GTK, PHP and then 
found PythondCard.

At a later stage I want to look at perhaps doing a network scan (Using 
NMAP) to find servers so that you don't have to manually enter each server.
For small sites it is easy to do this but for us we have over 150 servers.

So basically my new app should accomplish all this and be portable :-)

Not to optimistic I hope.

Ashley,

your app uses curses rather than a GUI - and this list is mostly 
populated by people writing GUI apps, particularly in PythonCard. I 
suspect most of the people on here will, like me, have no experience of 
curses, so we probably won't be able to be much help.

You'd probably be better on a more general Python list rather than here, 
but I'm not honestly sure which one.

That's one question I might be able to answer :-)

There are 2 cursors - the system cursor (usually controlled by mouse 
movement) and the text cursor within the app.

The text cursor is moved to 0,0 because you have the call scr.move(0,0) 
immediately before the scr.refresh()

I doubt if you can hide the system (graphics) cursor in a curses app - 
typically, only GUI apps are able to control it. Your app is always 
either busy, or in the time.sleep() call - and in both cases the "busy" 
cursor is the correct one.

Alex,

Thanks for the suggestions. I am new to Python and Pythoncard so 
anything I do will be new to me.

As Andy suggested I have started to scratch and itch with an app that I 
found lacking and want to improve.

I am sure you will all get used to me asking questions :-)

Thanks

Lance

Re: [Pythoncard-users] What Project is a good one to start on?

[Lance H. <lh...@ha...>]

Andy,

I am new to Python and Pythoncard and have just finished working through 
Alan Gauld's book "Learn to Program Using Python".
It has been a great way to learn about python and programming.

I was going to build an app that generates a webpage to display server 
status for Novell servers from a list of IP addresses and names.
I have been looking at the examples and I have seen your db browser and 
also the custdb sample.

The custdb sample has helped me to create the GUI and also to populate 
the fields from a csv file. I have a problem that the app does not 
refresh the list properly and was wondering if I should use sqllite instead.

Anyway thanks a million for the suggestion

Lance

[Pythoncard-users] curses + py2exe

[Ashley E. <as...@si...>]

Hi all

ive finally built my first little app, a MySQL process watcher, it works 
quite will and displays in a way similar to linux 'top'.

I have compiled the code into an exe using py2exe so i can distribute it 
amongst colleagues

only problem is, the app cursor is constantly in the waiting state (egg 
timer under winXP), which doesnt bother me, but if i change focus to another 
window, or try to move my app window, the process watcher app stops 
responding and generates a windows error.

so, how can i avoid the app from crashing, is this thread related in some 
way? or simply n00b coding. I have included a copy of the python code that 
was compiled below.

there are other minor things too, like how do i hide the cursor in the app, 
it currently gets moved to 0,0 on each refresh.

kind regards
Ash

Also, it's generally more difficult to learn too many different things 
at the same time, so try to pick an area where you already know some of 
the other parts, so it's (mostly) PythonCard that you are learning 
(and/or Python and/or wxPython).

For instance,  if you have already written some apps that analyze some 
data without a GUI - is there some aspect of the data that would benefit 
from being visualized ?  - so you could re-use your knowledge of how to 
read and handle the data.

Or - if you really want some suggestions "out of the blue"

 - pick some simple game and try that. (e.g. minesweeper - not Chess !!)
 - do something with a database (I never touch them myself, so have no 
specific suggestions :-)
 - spell checker (i.e. a PythonCard front-end to an existing checker)
        (or a spell checker for PythonCard resource files ??)
 - extend the findfiles tool to find and replace

[Pythoncard-users] python noob questions

[Ashley E. <as...@si...>]

Hi all

I am new to python and just getting to grips with it, although i have many 
years experience with PHP

anyway, my question is, I want to create a small script, or later an exe 
that shows the MySQL db processes with SHOW PROCESSLIST in the style of 
linux 'top' app which refreshes the display every x seconds, initially, i 
want to display this process list in a 'DOS' or shell type window, or run 
directly from DOS or the command prompt.

now, ive created a feww lines of code that fetch the rows from the db and 
print out a simple list of columns (in tuples?)

import MySQLdb
db = MySQLdb.connect(host="10.0.0.3",user="root",passwd="",db="mysql")
cursor = db.cursor()
cursor.execute("SHOW PROCESSLIST")
res = cursor.fetchall()
for row in result:
    print row
cursor.close()
db.close()

i just need to know how to turn this isto a looping affair, which refrshes 
the display, rather than kicking out the info every time and information on 
how to achieve this

so my questions are:

are there any libs i need which i can import into my script to make this 
easier, i already have wxpython and pythonCard installed?

would i be able to put this code inside a function and loop the function 
somehow:
def ShowProc():
    cursor.execute("SHOW PROCESSLIST")
    res = cursor.fetchall()
    for row in result:
        print row
    # some code here to refresh the display

eg
while True:
    ShowProc()

i eventually want to create a GUI that does all this for me so i can run the 
small app on my desktop while working, to keep an eye on the db servers i 
have to manage but im happy to just get this running command line for now as 
its the first thing ive tried in python

finally, am i even on the right track with this??

kind regards
Ash

Neat idea. Not sure about doing it with a Neural Network, but wondered 
if you know that they've been using this approach (radar + cameras + 
variable speed limits) in the UK for the last 11 years - so your 
Congressman can even get a junket to come to London to see it in action :-)

The M25 (major orbital freeway around London) has variable speed limits 
- see
http://www.tollroadsnews.com/cgi-bin/a.cgi/LjLtBrFHEdmcEIJ61nsxIA
or google "variable speed limit improve speed m25"

They can change the speed limit individually per lane, and have the 
speed limit signs approx every 1/4 mile (at the densest part where I 
used to sit in traffic jams :-)

The usual answer is to scratch your own itch. If you're looking to 
improve your knowledge and ability with PythonCard then I'd suggest 
starting with a small application that helps you out. For me it was an 
address book (which I'm not releasing because it wasn't very good) and 
then I moved on to a database query tool which became the dbBrowser sample.

If you're building something that you want and/or need then it becomes 
much more than a learning exercise and you'll be better for the experience.

Andy

The status bar is an attribute of the background, not a separate component.

If you are using the resourceEditor then from the Edit menu select 
"Background Info ...". On the resulting dialogue window you'll see a 
checkbox titled "Status bar on window". Select it.

It's in the "Background Info" (you can only have one, it can't be 
positioned, doesn't have all the usual characteristics, etc. so it 
doesn't need to be a full-blown component).

In layoutEditor go into menu "Edit / Background info ....", and check 
the box "Status bar on window". You can then refer to it in your code 
simply as  
   self.statusBar.text = "My new status"
or
   text = self.statusBar.text

This gives you a simple, single-field status bar; if you want more than 
that, you should be able to use the wxPython calls directly.

In wxGlade, I can add a StatusBar at the bottom of the panel.  Can I do this in

[Pythoncard-users] tabcodeEditor issues

[Tjerk H. <tj...@br...>]

There is one issue wich could make the oneEditor/tabcodeEditor better.
If you open another tab and choose codefolding and then go back to the =
first you=B4ve lost your codefolding.
I like to use the indentation guide and whitespacing but when I open a =
new file it opens
without these options altough they are marked in the View Toolbox.
Maybe codefolding, whitespaces and indentation guides could be part of =
the Style option?
I appreciate the dropdownboxes showing the widgets and the handlers =
available.

It will automatically bind the events to the methods if they exist.

So if you use the layoutEditor to add a button named "buttonMine", no 
binding happens.

If you then add a handler on_buttonMine_mouseClick to the Python source, 
then it will be bound for you next time you run. There's no need (and no 
purpose) in adding event stub code (since by definition the stub code 
does nothing) - as soon as there is "real " code there, it will be bound 
to the event.

When you run with the Message Watcher, it will show the "unused" events 
as gray, while the events for which there is code are shown in black (or 
you can click the checkbox to hide the unused ones).

No specific plans in the short term. However, there is already a feature 
which is (slightly) like that.

In 0.8.2 there are actually two versions of the resource editor 
(resourceEditor and layoutEditor), and two versions of the code editor 
(codeEditor/codeEditor and oneEditor/tabcodeEditor). In both cases, the 
latter is the newer version, and we are fairly close to removing the 
older ones, as the newer versions get enough mileage under them to know 
they are OK.

tabcodeEditor differs in two ways from the older codeEditor
   - you can edit multiple files simultaneously, in a "tabbed notebook"
   - there is some minor integration with resource files.

If the file you are editing has a matching .rsrc.py file, then the 
"drop-down" choice above the notebook will be populated with a list of 
all your widgets. Selecting one of them will then display another 
drop-down, showing all the events for that widget type; those for which 
a handler has been found will show with a "+" (plus sign). Selecting one 
of these will find the relevant handler in the source file, while 
selecting an event for which there is not yet a handler will insert a 
stub handler (at current cursor position = beware !)

It's an 'empty' stub (i.e. 3 lines of code) so it's not a big deal to 
have it inserted - the important thing was seeing the list of widgets 
and then a list of events.

btw - the choice of name for the tool (i.e. 'oneEditor') might give a 
clue to the long-term thinking - but it's not solid enough to call it a 
'plan' yet :-)

[Pythoncard-users] Automatic generation of event bindings

[Scott C. <sco...@mi...>]

I'm using PythonCard 0.8.2 on Windows XP Pro with Python 2.4.3.
When I add a widget to the screen and have it generate the code for it, it's not 
automatically generating code stubs for the event handlers.  Can I make it do that?

I run it with debug options on and I see it's adding bindings for a few things, 
but not the widgets I added.

Are there plans to make it work more like Visual Basic does where you could 
right-click on a widget edit the Python code for the event handler you select?

It sounds like a tiny but useful time saver, so I'd vote for putting it 
in eventually, even if it's Windows-only.
