[Pythoncard-users] How can I get the old style calendar back?

[Tiberiu I. <ti...@li...>]

Hi!
I've upgraded one of my apps from pythoncard 0.7 to the latest 0.8 
Unfortunately, the calendar widget has been modified (it no longer has 
drop-down boxes for month and year), and for my application it would be 
better to have those back. I've tried fiddling with the window style 
flags from wx, but I couldn't get it to work the way it used to. Besides 
creating separate widgets and linking them to the calendar with code, is 
there a possibility to get the old style back?

Thanks for your help,
Tiberiu Ichim

I'm just coming in on the middle of this. If you want to focus on an
item in a list use .selection =3D index
If this isn't what you were looking for, sorry, I just joined this list.

I'd chime in with Alex, I just added sizers to my app, and it was much
easier than I thought it'd be. One thing to keep in mind, the size you
make the components in the resource editor is the default size of the
object when the sizer places them... So you might want to make them the
minimal size. 

Also, in my app I have 3 multicolumn lists that take up the majority of
the space on the window. Adding sizers that sized them proportionally to
each other was doing very strange stuff until I made the initial size of
each multi-column list the same 'unit' size (100x100).

I'm also on Ubuntu, using wxPython 2.6.1.0. I don't see it on my
StaticText fields... Mark, which version of wxPython are you using? And,
which version of PythonCard?

If you want to see what the widgets look like on my system, you can look
at the presentation I gave the other day:

    http://www.utahpython.org/meetings.spy

    (a screenshot of the widgets sample is on page 6 of the .pdf)

You could also do two resource files, run your app with '-l' on the
command-line to see the set of resource files it tries to load at
startup. But, I think you'd end up much happier using sizers. It does
take work to get them right, but in the end it'll be less tweaking busy
work.

What do you want to do w/ regard to packaging it up? Does it have
dependencies on other applications/shared libraries? If so, you might
need to look into .deb or .rpm packaging. If not, I'd just bundle it all
up in a .tgz file and include adequate documentation in a README file.

> Do you need to re-retrieve the whole table ?

Technically at this time, no.

But in theory, this database could be accessed by multiple systems
at the same time...  And thus it is safer to refresh the entire table
then it is to reread just a single row.

Reading the table from the database is very fast...  The majority of the
time involved in the gather_data routine is the Dialog window redrawing
the
data....

	Quite possible.  I just did a simple check to see how it woruld
work.

> added), it could be in a different row number - no ?

	Yes...  It could...  But even if the data is indifferent
position,
I don't mind the cursor being where it was previously. =20

	These are software titles, etc...  (It's a auditing system...)

	So if your editting "Norton Utilities v2.0", probably you'll
want to edit something nearby...

> Can't you remove that loop entirely, and get the line number=20
> while loading the table from the DB :

	It is possible.  For some reason (I forget), I did not want to
do that......  I'll make a quick model...

	Possibly lost in the email was a small issue...

1) SetSelected does not reposition the list to be in the visible area.
Is there some other way to force the selectedvalue to be in the visible
area of the dialog?

Do you need to re-retrieve the whole table ?
Can you not remember which row you were editing and deal only with that ?
    (I'm naive about DBs - can you tell ?  :-)

I'm surprised that the time to load the whole table from the DB, then 
load that whole thing into the multicolumnlist is small enough for the 
extra 1-2 seconds to matter.

But .... it looks to me as though what you're doing in the loop

        for x in xrange(0, len(self.components.MultiColumnList1.items)):
            if current_item == self.components.MultiColumnList1.items[x][0]:
                highlited = x
                break
is getting the row number where the current_item was *before* any edit to the db.

I'd have thought that once you'd edited (or deleted or added), it could be in a different row number - no ?

Can't you remove that loop entirely, and get the line number while loading the table from the DB :

        data = []
        line = []
	highlited = -1
	count = 0
        for x in vsoftware:
            for y in x:
                line.append ( str(y) )
            data.append ( line )
	    if line[0] == current_item: highlighted = count
	    count += 1
            line = []

        self.components.MultiColumnList1.items = data
        print dir(self.components.MultiColumnList1)
        self.components.MultiColumnList1.SetFocus ( highlited )


If you can't use that, then the other possibility is to retrieve the 
entire table, and scan that. This saves a significant overhead for 
accessing each item within the multicolumnlist - but obviously can't be 
done if your table is too large - i.e. 400 x ?? columns
(if it is too large, you may still be able to retrieve the datamap 
dictionary, and access that - but if you can do this it is easier)

What I tried in my copy of the sample/multicolumnlist was

>         #   current_item = "Yes"
>         current_item = "Not to be found"

and this gave times of ~ 6 seconds for the first loop, versus no 
measurable time for the second.

> Should be something like on_myList_itemActivated()

Ah...  I see..   Obvious.... =20

That's now working...

Now regarding the reset of the selected item on a multicolumn list...

	def gather_data ( self ):
        current_item    =3D self.last_picked[0]
        highlited       =3D -1
        for x in xrange(0, len(self.components.MultiColumnList1.items)):
            if current_item =3D=3D
self.components.MultiColumnList1.items[x][0]:
                highlited =3D x
                break
               =20
        vsoftware =3D None
        self.components.MultiColumnList1.items =3D []
        self.components.MultiColumnList1.columnHeadings =3D []
        headings =3D []

        vsoftware, structure =3D self.odbc_database.select_statement (
fetch=3D"*",
                                      table=3Dself.database_name,
orderby=3Dself.orderbys)
        for x in structure:
            headings.append ( x[0].replace("_", " ") )
        self.components.MultiColumnList1.columnHeadings =3D headings

        data =3D []
        line =3D []
        for x in vsoftware:
            for y in x:
                line.append ( str(y) )
            data.append ( line )
            line =3D []

        self.components.MultiColumnList1.items =3D data
        print dir(self.components.MultiColumnList1)
        self.components.MultiColumnList1.SetFocus ( highlited )

The penalty is too high.....

Here's some background.  The multicolumn list is a representation of
what data is in a database (accessed via ODBC)...  The gather_data
function is used to refresh the data in the database view...

After any changes (Editting, Adding, Removing) I need to refresh, but
the table could be 400+ entries.

It would be rather annoying for a user to make a change at the end of
the table, and then have the table refreshed, and have to scroll all the
way down to the end (again).....

SetSelection works to highlight the text.  But it doesn't change the
visible portion of the table to be in the viewing area....=20

The verified Software table is only roughly 100+ items, but if I use the
for loop...

        for x in xrange(0, len(self.components.MultiColumnList1.items)):
            if current_item =3D=3D
self.components.MultiColumnList1.items[x][0]:
                highlited =3D x
                break

It adds roughly a 1-2 seconds to the load process....

Any suggestions?

Yes, I tried (from memory, I'm at home)...

There's no PythonCard method to do this directly. You can use the 
wxPython methods (I stole / adopted this code from the 
components/multicolumn.py). 

I took the multicolumnexample in the samples directory, added a button 
called "which" and added the code below.
It prints out the list of selected item row numbers - and then makes the 
row following the first selected one be (also) selected.

You'd need to (assuming you want to) first de-select the current 
selection, then select 667 as you want - something like
    for i in items:
        self.components.theList.SetSelection(i, 0)    # second param 0 
to deselect
  self.components.theList.SetSelection(667)

You could cheat. Make the row index either the first column or last
column of the row (first if you don't mind it showing, last if you want
to 'hide' it), then look at that column in the return value of
getStringSelection()
    
for example, if it's in the last column :
    rows = self.componenets.myMlist.getStringSelection()
    rowIndex = rows[0][-1:][0]

I should start off by saying I've never run Pythoncard on Linux (and 
don't have any access to Linux to try it), so these answers should be 
treated cautiously.

For text and control sizing, there is no good *native PythonCard* 
solution right now. The best way I know is to use wxPython's sizers to 
make your layout fully self-sizing. That will typically make it nicer to 
use anyway, and should handle issues like different system font sizes, 
drop-down arrow sizes, etc. along the way.

There's a good example of using sizers in the findfiles utility 
(PythonCard/tools/findfiles), and there's some half-decent documentation 
on sizers in the wxPython documentation/demo download.

No idea. Is it a TextField, or a StaticText ? Do all such fields get a 
border on Linux ?

Undo/Redo code for what kind of component or control ?
Could you expand a bit more on this item ?

Shouldn't need to if you can wrestle the layout into sizers - it's not 
always easy to find the right combination of sizers to get the layout 
you want.

I definitely can't answer that one ...

[Pythoncard-users] Cross-platform issues

[Mark C. <ma...@ma...>]

Hello.

I've written an app using PythonCard in Windows.  However, when I take 
the code and run it on Ubuntu Linux (Ubuntu 5.04, Gnome) using my 
laptop, it has some issues.

Specifically:
- The drop-down choice box, because Gnome renders it with both an up and 
down arrow, is much bigger.
- Fonts.  I left them at default in Windows, which is Microsoft Sans 
Serif size 8.  However, in Gnome, it defaults to Sans size 10.  The size 
change resizes buttons on me, screws up my form layout, and just looks 
terrible.
- I have a text field (like a VB label) beside my choice drop-down.  On 
Linux, it's got a border around it for some reason.
- Undo/Redo.  I copied the undo/redo code from one of the Pythoncard 
sample apps, and it works fine in Windows, but doesn't work at all in Linux.

Everything else works fine, which is very good.  But I need to clean up 
the user interface, which goes from looking great in Windows to crap in 
Linux.

Anybody have any tips regarding cross-platform development?  Am I going 
to have to maintain two versions of any software with a GUI?

On another note, I use NSIS to package a nice installer for Windows. 
What's the best way to package it up for Linux users?

If nothing else, you can do a match of the list to get
the number.  

if
self.components.myMulList.GetSelectedString==self.components.myMulList.items[665]:

May be there is an easier way that others can point

Don't know how to set to a specific number but in my
case, I've been using the SetStringSelection method.

x=self.components.myMulList.items[666]
self.components.myMulList.SetStringSelection(x,select=1)

1) How do I find out what Row the user has highlighted?  I know
GetSelectedString will return the text, but I'm interested in finding
out row #666 is selected.

	a) How do I set the active row back to 667 or after I reload the

RE: [Pythoncard-users] Calendar Widget, setting the date shown to a specific date.

[Schollnick, B. <Ben...@xe...>]

Okay, I found a different way to handle changing the date in the
calendar control.

    date =3D time.strptime ( data[0][3], "%a %b %d %H:%M:%S %Y")
    import datetime
    datevalue =3D datetime.datetime ( date[0], date[1], date[2] )
    dlg.components.TimeDateStampfield.date =3D datevalue

	While this obvious...  I initially did not get this to work.  I
forget exactly
what was previously tried...  But I believe I initially tried to pass
the date string...

	SetDate is a red heering....  It's wxPython....  And I have not
found
any way to use it....  ( wxDateTime isn't anywhere to be found on my
wxPython
installation...)

[Pythoncard-users] Calendar Widget, setting the date shown to a specific date.

[Schollnick, B. <Ben...@xe...>]

Folks,

	I'm using a calendar widget....  But I have run into a issue
that I can't seem
	to resolve...

	Is there a way to set the Calendar widget to a specific date?  I
see the
	SetDate function, but I am unable to find the syntax/format for
that function...

	I need to set the calendar to match the data it is
representing....

	I briefly checked the samples, but I did not see any that used
the calendar, and
	set the date to anything but the default of Now... (The calendar
widget appears
	to default to NOW().)=20

	Any hints?

RE: [Pythoncard-users] Stopping an animation sequence.

[Don S. <saw...@st...>]

Rohit,

You might set up your code to run each iteration of your animation
separately and asynchronously, such as when a timer event executes. The
"flock.py" sample shows an example of this method.

I also am new to PythonCard, so if any reader of this message can =
correct my
advice, please do!

The problem is that your code runs continuously, so there is no 
opportunity for the click on the "stop" button to be processed, and so 
self.stopAnimation can't be set. This also means that you can't, for 
instance, move your window while the animation is running.

Easiest fix is to add
            # give the user a chance to click Stop
            wx.SafeYield(self, True)
inside your loop. This gives an opportunity for other things to happen.

A better fix, IMO, is to use timers instead of a loop. You create a time 
in your initialization code, then when the start button is pressed, you 
start the timer. Each iteration of drawing is done within the timer 
handler, and the stop button simply stops the timer.  See the 'flock' 
sample for an example of doing this. 

There are two reasons I say that this is better is:

1. You can more easily extend it to do more animations, perhaps at 
different time scales, by having multiple independent timers; the 
loop-with-yield mechanism is more restrictive.
2. You can do other things in the program while the timers continue to 
operate - if you do something else within the app during a loop+yield, 
the animation stops. For instance  - I tested this out by creating a 
simple app with File/Help menus, and adding the buttons and canvas to 
it. I checked that, indeed, the stop button didn't work; then added the 
SafeYield() line, and now the stop button works immediately. Now, if I 
hit start and then the select File menu, the ball moves briefly then 
disappears while I keep the menu selected; once I release the menu, the 
ball continues its movement.  But in the flock sample, the animation 
continues while the menu items are selected.
