WxImageButton on Linux

philippe_DALET · April 19, 2019, 12:53pm

Hello,

I started to upgrade Pythoncard for python3.

All components work on linux (64 bits, Ubuntu 180.4 and 16.04, gtk2 or gtk3, python 3.5 and 3.6 and 3.7) except wxImageButton .

It works properly on windows seven.

Are you sure that self._bitmap.getBits() is returning a wx.Bitmap and not some other Bitmap class? (Such as PC’s graphic.Bitmap.)

Yes, self._bitmap.getBits() is returning a wx.Bitmap.
It runs properly on windows. It seems that it expects another parameter.

Is it possible to debug with python, then in C with an IDE on linux ?

It runs properly on windows. It seems that it expects another parameter.

Is it possible to debug with python, then in C with an IDE on linux ?

The C++ wrapper code where that exception is raised is identical on each platform and it hasn’t yet gotten to any platform-dependent wxWidgets code, it’s just type-checking the parameters to decide which wxBitmapButton constructor to call. So if it works on one platform and not another then it must be differences in the inputs from the Python side of things.

Ah, I just noticed something odd:

File “/usr/local/lib/python3.6/dist-packages/PythonCard/components/imagebutton.py”, line 56, in init

wx.BitmapButton.__init__(self, parent, id, self._bitmap.getBits(),pos, size, style, validator, name)

TypeError: Control(): arguments did not match any overloaded call:

Somehow it is not trying to call wx.BitmapButton.init but wx.Control’s init. Does PythonCard do any monkey-patching or something that could be replacing wx.BitmapButton with wx.Control?

For example, I can duplicate the exception with code like this:

wx.BitmapButton = wx.Control

class TestButton(wx.BitmapButton):

def __init__(self, parent, id, bmp, pos=wx.DefaultPosition, size=wx.DefaultSize, style=0:

Hello robin,

This bug does not come necessarily from wxpython.

With python 3.7.2 on Windows seven, this bug was already present. No more with python 3.7.3.

This is the problem:

class Image(widget.Widget, StaticBitmap):

...

class ImageButton(image.Image, wx.BitmapButton):

...

You have the ImageButton class deriving from two different widget classes. Not only can you not have a single widget be two different types of widget at the same time, but SIP does not support multiple inheritance of wrapped classes, which is the problem this code runs into first. (The wrong init being called when you call wx.BitmapButton.init) Even if SIP had supported it then there likely would have been errors from wxWidgets or the platform APIs.

If you change the ImageButton class to this then it will work:

class ImageButton(widget.Widget, wx.BitmapButton):

which is apparently what was intended since there is already a call to widget.Widget.init in the code.

Philippe,

Can you duplicate the problem in a small stand-alone sample?

Hello robin,

This bug does not come necessarily from wxpython.

With python 3.7.2 on Windows seven, this bug was already present. No more with python 3.7.3.

It runs properly on windows. It seems that it expects another parameter.

Is it possible to debug with python, then in C with an IDE on linux ?

The C++ wrapper code where that exception is raised is identical on each platform and it hasn’t yet gotten to any platform-dependent wxWidgets code, it’s just type-checking the parameters to decide which wxBitmapButton constructor to call. So if it works on one platform and not another then it must be differences in the inputs from the Python side of things.

Ah, I just noticed something odd:

File “/usr/local/lib/python3.6/dist-packages/PythonCard/components/imagebutton.py”, line 56, in init

wx.BitmapButton.__init__(self, parent, id, self._bitmap.getBits(),pos, size, style, validator, name)

TypeError: Control(): arguments did not match any overloaded call:

Somehow it is not trying to call wx.BitmapButton.init but wx.Control’s init. Does PythonCard do any monkey-patching or something that could be replacing wx.BitmapButton with wx.Control?

For example, I can duplicate the exception with code like this:

wx.BitmapButton = wx.Control

class TestButton(wx.BitmapButton):

def __init__(self, parent, id, bmp, pos=wx.DefaultPosition, size=wx.DefaultSize, style=0:

    wx.BitmapButton.__init__(self, parent, id, bmp, pos, size, style)

Hi Robin,

it works fine. Thanks a lot.

This is the problem:

class Image(widget.Widget, StaticBitmap):

...

class ImageButton(image.Image, wx.BitmapButton):

...

You have the ImageButton class deriving from two different widget classes. Not only can you not have a single widget be two different types of widget at the same time, but SIP does not support multiple inheritance of wrapped classes, which is the problem this code runs into first. (The wrong init being called when you call wx.BitmapButton.init) Even if SIP had supported it then there likely would have been errors from wxWidgets or the platform APIs.

If you change the ImageButton class to this then it will work:

class ImageButton(widget.Widget, wx.BitmapButton):

which is apparently what was intended since there is already a call to widget.Widget.init in the code.

I’m not sure in what universe that 109,405 lines of Python code, plus tons of data files, that uses matplotlib and scipy is considered a “small stand-alone sample”

In case it’s not clear -/ Robin is referring to this:

https://wiki.wxpython.org/MakingSampleApps

And not only does it make it easier for others to hell you, isolating the problematic code is very likely to help you find the solution yourself.
