You have to destroy the wxDiagram object yourself.

Please see the wxPython ogl demo and the Boa source code (OGLViews.py)
for examples of this.

Excellent Riaan.  Thanks so much for the help.  It actually did read
Docs/boa/apphelp/MixingSource.html (several times), its just that I didnt
understand it.  But I am learning fast and your last post helped quite a
bit.  Now my skeleton application works...sort of.  I can now open it with
the Inspector, but unfortunately the new code has introduced a new problem.
It gives an error after execution, suggesting that I have memeory leaks.  Do
you know what would cause this?

7:33:33 PM: There were memory leaks.
7:33:33 PM: ----- Memory dump -----
7:33:33 PM: wxDiagram at $1183298, size 32
7:33:33 PM: wxObject at $11A2258, size 28

7:33:33 PM: Number of object items: 2
7:33:33 PM: Number of non-object items: 0

Im sure you are a very busy man and have other things to do than answer my
questions, but I really do appreciate the help getting started.  Just let me
know if I am wearing out my welcome.  Once I get some basics down, I think I
will be fine.

Please follow the instructions that I posted previously, your code
should then be equivalent to this:

    def __init__(self, parent):
        self._init_ctrls(parent)

        self.diagram = wxDiagram()
        self.diagram.SetCanvas(self.scrolledWindow1)
        self.scrolledWindow1.SetDiagram(self.diagram)

As the Boa application help says, you should not add code to the
methods that Boa generates and maintains; the _init_* methods.
In the help you are also encouraged to make your the changes
in the __init__ method after the self._init_ctrls call.

> If I wanted to fix the crash on exit problem

Add this snippet of code to the bottom of Preferences.py

try: sys._wxApp_Cleanup = wx.__cleanMeUp
except: pass

to fix it.

Learning to use CVS is of value to any developer IMO.
Boa is not released that regularly, so if you need support for the
latest wxPython or new features/fixes then it's up to you to learn CVS.
There's plenty of help on the web and in the Boa application help.

I do suggest leaving it until you are more familiar with everything.

You can have more than one Python installation at a time, but as I
said, this is a last option.

Boa 0.1.0 was developed on wxPython 2.3.2 and Python 2.1, so that
is where it will run the best.

That said, you now have the major hickups of 0.1.0 patched so you
should be fine.

> Again, pardon my lack of experience...with a little help I will learn

Best advice I can give would be to make more use of the SourceForge
tracker and the Boa application help.
(esp. Docs/boa/apphelp/MixingSource.html).

Learning Python/wxPython should be fun, so enjoy it!

RE: [Boa Constr] 2 problems-- wxMenu and python crashing

[John B. <joh...@om...>]

Thanks Riaan.
I did go to the web site and made the suggsted change in the
UtilCompanions.py file.  Now I can add a menu.  It works great.

I did try your suggestion on the initialization lines for the canvas.  I had
to change them a bit to get it to work [see below...wxFrame1 (which is self)
did not have an attribute "diagram"].  Im not sure if I can draw yet, but
the application does execute at least.  No errors.  The problem is though
that by adding the new code into the init section, Boa no longer will allow
me to use the Frame Designer.  It tells me there are "too many sections".
Is there a way around this?  It kind of defeats the purpose if I can't use
the graphical layout abilities of Boa.

        self.scrolledWindow1.diagram = wxDiagram()
        self.scrolledWindow1.diagram.SetCanvas(self.scrolledWindow1)
        self.scrolledWindow1.SetDiagram(self.scrolledWindow1.diagram)

I had to place the above code below where scrolledWindow1 was initialized, I
see, or else it didnt know what scrolledWindow1 was.

If I wanted to fix the crash on exit problem I could upgrade to the new CVS
version, but Im not sure how to do that.  I went to the CVS site and I see I
can download several different modules, but which ones do I want and how do
I install them in Windows?  Do I just copy them over the old folders?

I could also downgrade to Python 2.1, but Im wondering if I would have to
uninstall 2.2 and wxWindows and Boa etc, since they are all in the same
Python22 directory.

Again, pardon my lack of experience...with a little help I will learn fast.

The problem is that you are using a wxShapeCanvas that has not been 
initialised properly. When it's initialised properly, it behaves and 
does not crash.
Add the following code to your __init__ method beneath _init_ctrls:

        self.diagram = wxDiagram()
        self.diagram.SetCanvas(self.scrolledWindow1)
        self.scrolledWindow1.SetDiagram(self.diagram)

I see you almost got this in the next mail you sent, close ;)

Re: [Boa Constr] 2 problems-- wxMenu and python crashing

[Riaan B. <riaan@e.co.za>]

Hi John, 

These problems are fixed in CVS. The solutions are described in the 
forums and bug tracker.

As a last resort you may switch to Python 2.1.

BTW, the crash at shutdown happens after eveything has closed and 
destroyed so it won't cause data loss.

[Boa Constr] ...at the risk of asking TOO many questions...

[John B. <joh...@om...>]

Hi.  I hope I am not using up all my good graces by asking too many
questions here (any suggestions on etiquite would be appreciated).  But I
have one commont and one more question.

The comment is on my last post about Python crashing after I click a mouse
event in my created wxShapeCanvas.  Actually, it doesnt even need to be a
mouse event--even with all events removed, Python crashes whenever I click
anywhere in the canvas.

Second...and this is real simple...I am a real newbie...how do I make a
panel active without the mouse?  I would like to instruct my program to draw
a line on the canvas (named "scrolledWindow1"), but I cant figure out how to
make the following lines work:

self.scrolledWindow1.diagram=wxDiagram()
self.SetDiagram(self.diagram)
self.diagram.SetCanvas(self)
...

I got these and several related lines from the wxOGL demo.  But when I run
it Boa tells me that self is not defined. Omitting the "self." part or
changing it to "wxFrame1." (the parent, I assume) does not work either.  How
do you instruct wxWindows to do something on a desired frame or panel
without using mouse events?

I thought that since I cannot click on the canvas without Python crashing,
maybe I could hard wire in some code to draw a test line.

John

RE: [Boa Constr] newbie question -- using Boa for creating a drawing canvas

[John B. <joh...@om...>]

Hello Riaan, John, and all.  The wraparound for the wxShapeCanvas widget
still seems to have one problem in it.  I created the custom canvas, as we
discussed, but it does not seem to handle mouse events.  Using wxBell() as a
test, I can get a mousedown event to ring the bell on a regular wxPanel, but
on the new canvas it causes python to crash.  No message is given, just a
python crash.  The applicable code is:

class wxBoaShapeCanvas(wxShapeCanvas):
    def __init__(self, parent=NULL, id=-1, pos=wxPoint(224, 16),
          size=wxSize(200, 304), style=wxBORDER, name='shapecanvas'):

        wxShapeCanvas.__init__(self, parent, id, pos, size, style)
        self.SetName(name)
-------------------------------

class wxFrame1(wxFrame):
    _custom_classes = {'wxScrolledWindow': ['wxBoaShapeCanvas']}

    def _init_ctrls(self, prnt):
        wxFrame.__init__(self, id = wxID_WXFRAME1, name = '', parent = prnt,
pos = wxPoint(353, 110), size = wxSize(484, 424), style =
wxDEFAULT_FRAME_STYLE, title = 'wxFrame1')
        self._init_utils()
        self.SetClientSize(wxSize(476, 397))

        self.panel1 = wxPanel(id = wxID_WXFRAME1PANEL1, name = 'panel1',
parent = self, pos = wxPoint(8, 0), size = wxSize(176, 384), style =
wxTAB_TRAVERSAL)
        self.panel1.SetForegroundColour(wxColour(255, 128, 255))
        self.panel1.SetBackgroundColour(wxColour(0, 255, 0))
        EVT_LEFT_DOWN(self.panel1, self.OnPanel1LeftDown)

        self.scrolledWindow1 = wxBoaShapeCanvas(id =
wxID_WXFRAME1SCROLLEDWINDOW1, name = 'scrolledWindow1', parent = self, pos =
wxPoint(216, 16), size = wxSize(232, 368), style = wxTAB_TRAVERSAL)
        self.scrolledWindow1.SetForegroundColour(wxColour(128, 0, 255))
        self.scrolledWindow1.SetBackgroundColour(wxColour(0, 0, 255))
        EVT_LEFT_DOWN(self.scrolledWindow1, self.OnScrolledwindow1LeftDown)

-----------------------------------
    def OnScrolledwindow1LeftDown(self, event):
        wxBell()
------------------------------

Actually, the bell goes off and then Python crashes.  Again, I am using Win
XP.  Any ideas as to why this might be occuring?  I am stumped.  I can,
however, place a static bitmap on the canvas.  That seems to work just fine.

Thanks Riaan.  I had to modify your suggestion a bit to get it working.
Here is what I used:

class wxBoaShapeCanvas(wxShapeCanvas):
    def __init__(self, parent=NULL, id=-1, pos=wxPoint(224, 16),
          size=wxSize(200, 304), style=wxBORDER, name='shapecanvas'):

        wxShapeCanvas.__init__(self, parent, id, pos, size, style)
        self.SetName(name)

That seems to work OK.  I have another question though.  I would like to
place a bitmap (or gif if I could) on the canvas and then be able to rotate
it when I want.  I could use the static bitmap control in Boa, but that
references a filename for the bitmap.  So if I want to rotate it (using
image.Rotate() from PIL), I would have to open the file, rotate it, save it
to a temp file, and then open it again with the bitmap control.  Is there a
more efficient way to do this?  Unfortunately, wxShapeCanvas does not have
methods to paste a bitmap to the canvas.  I am very new (to OOP, Python,
Boa), so maybe I am missing something here that would make the job easy.
Any suggestions are appreciated.

[Boa Constr] 2 problems-- wxMenu and python crashing

[John B. <joh...@om...>]

Hi:
I just downladed and installed the latest version of Python, Boa and related
files, and I am having a couple of problems that were mentioned perviously
in the sourceforge open discussion. I run Windows XP, by the way. The first
problem is with adding menu items and it also occurs when adding
wxImageLists. It is the problem Steve has written about below:

------------------------------------------------------
By: holdenweb ( Steve Holden )
 Menu items cannot be added/edited
2002-04-22 15:38
When I try to add a Menu widget to the Data tab of a wxFrame I see the
following error traceback:

TypeError: unbound method properties() must be called with CollectionDTC
instanc
e as first argument (got MenuDTC instance instead) ....[and so on]

[the reply by Keven:]

By: kevin_gill ( Kevin Gill )
 RE: Menu items cannot be added/edited
2002-04-23 02:50

I had these problems when I installed beta1. It appears that there was
global changes to some objects to differenciate between design time and run
time versions, and some lines got left out.

I include them below.


Companions/Companions.py
line 1131, changed ContainerDTC to Window DTC

def persistProp(self, name, setterName, value):
if setterName == 'SetImageList':
imgList, listType = string.split(value, ',')
imgList, listType = string.strip(imgList), string.strip(listType)
for prop in self.textPropList:
if prop.prop_setter == setterName and prop.params[1] == listType:
prop.params = [imgList, listType]
return
self.textPropList.append(methodparse.PropertyParse( None, self.name,
setterName, [imgList, listType], 'SetImageList'))
else:
#ContainerDTC.persistProp(self, name, setterName, value)
WindowDTC.persistProp(self, name, setterName, value) #KG ####

Companions/UtilCompanions.py
line 220

def properties(self):
props = UtilityDTC.properties(self) ### KG ###
props.update({'Items': ('NoneRoute', None, None)})
return props
-------------------------------------------------------

I do not understand if I too should change these lines of code (maybe it was
updated since April).  In fact the line numbers Kevin refers to do not seem
to be the ones in the code.  Anyway, I do not understand what pieces are to
be changed and what are to be left alone.  Could anyone give some
newbie-friendly advice on this?

Here is my second problem.  It is one that notnameless had as shown below:

------------------------------------------

By: notnameless ( See login name. )
 Hmmmm...
2002-05-08 19:57

Whenever I close Boa I get the following error:
Python has caused an error in WSMXSW232.DLL. Python will now close. I know
this is a wxWindows, or wxPython error and wonder if there is a way to get
rid of the error. I am running Win ME.

------------------------------------------

Actually, I do not get the exact message, but Python crashes every time I
exit Boa unless I exit it by shutting down the DOS command window. Any
suggestions as to how to fix this?

John Bell gave the correct advice, but wxShapeCanvas is unfortunately 
an exception to convention of supporting a 'name' keyword argument.

Just for consistency I wish this could be added to wxWindows, Robin?

Personally I think you should do the creation of the wxShapeCanvas 
manually after the generated code is called in __init__. This is what 
I always do with the dynamic or non supported elements of any wxFrame.

If you do have compelling reasons to want the object (or it's 
nearest equivalent which is wxScrolledWindow) in the design time 
environment you may define a small adapter class which just wraps
the constructor signature (untested).

class wxBoaShapeCanvas(wxShapeCanvas):
    def __init__(self, parent=None, id=-1, pos=wxDefaultPos, 
          size=wxDefaultSize, style=wxBORDER, name='shapecanvas'):
        wxShapeCanvas.__init__(parent, id, pos, size, style)
        self.SetName(name)

with

    _custom_classes = {'wxScrolledWindow': ['wxBoaShapeCanvas']}

RE: [Boa Constr] newbie question -- using Boa for creating a drawing canvas

[John B. <joh...@om...>]

Thanks for the help John.  But I see (at least) one more problem.  Does
anyone have a suggestion?  I can build a canvas class as a derived class of
one of the container classes, maintaining the same initialisation signature
as the container class and then using it as a Custom Class, as suggested,
but it produces errors because the wxShapeCanvas widget that I need to use
does not take "name=..." in its constructor.  Because all the other
containers do, they would all produce an error.  Short of hand typing the
whole thing in for the widget, does anyone have a suggestion as to how to
get around the "name=..." problem in defining the new constructor?

I presume that what you mean is that you can't find
any form of "Canvas" type control on the Palette. 
This is not surprising since wxPython has no control
of this type.  You need to associate a Device Context
with the frame and draw to that.  There should be an
example in the wxPython demo.

From a Boa integration point of view your options are
either to add the extra code in the __init__ block by
hand (along with required event handlers in the module
block) or to build a canvas class as a derived class
of one of the container classes, maintaining the same
initialisation signature as the container class and
then use it as a Custom Class (see Boa documentation).

[Boa Constr] newbie question -- using Boa for creating a drawing canvas

[John B. <joh...@om...>]

Hello:
I am new and hoping to complete an easy (?) project.  In a nutshell, I need
to place a gif pic (a pic of a graph) on a frame, then draw litle boxes
around points on the graph and collect the coordinates for the box centers.
Sounds simple enough....but I downloaded Boa and see that it has no canvas
tab on the Editor window.  How does one go about placing a drawing canvas on
a frame using Boa?

Any help is appreciated.  John

[Boa Constr] Help!?! Tutorial doesn't work for 0.1.2a

[Robin S. <Rob...@co...>]

I just installed 0.1.2a and I am trying to follow the tutorial.  However,
it's not working.  I'm in section 2.4 and the submenu 'About' that I created
for mnuHelp doesn't *have* the options shown in the Constr pane of
Inspector.  Nor does mnuHelp have any events available under the Evts pane
of the Inspector.  Am I doing something wrong?

[Boa Constr] Saving the Title of a menu

[Robin S. <Rob...@co...>]

I am following the tutorial and I am at node 2.4.  It says to set the titles
of the menubars to 'File' and 'Help'.  I've tried that every way I can think
of, but I can't get it to save these values.  What am I doing wrong?

Re: [Boa Constr] CVS

[rboulanger <ro...@bl...>]

It is it worth anyway.

Go into the parent directory where boa is currently installed for 
Example C:\Python22\Lib\site-packages\wxPython\tools

then use the following commands: (I assume you have a commandline 
cvs.exe installed

When prompted for a password for anonymous, simply press the Enter key.

cvs 
-d:pserver:ano...@cv...:/cvsroot/boa-constructor 
login

cvs -z3 
-d:pserver:ano...@cv...:/cvsroot/boa-constructor 
co boa

You don't need any Compiler. Boa is entirly written in Python, go then 
to the Boa directory and simply type: python Boa.py.
It will be "compiled on the fly" when you start it the first time

[Boa Constr] CVS

[Robin S. <Rob...@co...>]

I'm new to Boa and I am using 0.1a. My question is this - Is the CVS version
that much better and how difficult is it to get/build? Ok, that's more than
one question, so here are a few more: We use Perforce at work. Will that
work, or do I need something else, if so, what? Is there a webclient that I
can use so I don't have to install anything? Will it build under .NET? If
not, I would assume that it will under VC++ 6.

Yes, this is turning into an FAQ :)

I will probably end up moving the docs back into the CVS repository.
(Personally, I only want code in the repository)

You may get the Tutorial (and the Boa application help) from the
0.1.0 source (or exe) release.

Hi;

I've seen posts and other allusions to a tutorial/documentation for boa, but
I'm unable to find it, even doing a CVS checkout from SF. Any pointers would
be appreciated.

Not really, breakpoints in other modules works fine for me.

Are you sure all the files are saved?

What happens when you step into (F7) a call to example2?

Re: [Boa Constr] Error message when quitting Boa

[Riaan B. <riaan@e.co.za>]

Hi Ed,

Boa 0.1.0 runs best on Python 2.1 and wxPython 2.3.2.

The crash-after-exit bug and problems Boa had with Python 2.2 are fixed 
in the CVS repository.

To prevent the crash-after-exit bug, at the following to the bottom of
Preferences.py:

try: sys._wxApp_Cleanup = wx.__cleanMeUp
except: pass

Riaan.
