Code changed and results in error of my programm

GNU Radio

Hi All,

one of my gnuradio programms do not work anymore, because
some changed the code.

My error Message is:
self._variable_text_box_0_control = grc_wxgui.text_box_control(
AttributeError: ‘module’ object has no attribute ‘text_box_control’

What is the new name ?

regards Markus

Forget this message. I do not need this Program anymore.

The callback controls module in grc was replaced with the forms module
http://gnuradio.org/trac/browser/gnuradio/trunk/grc/src/grc_gnuradio/wxgui/forms

The idea is that this forms module will get merged into wxgui and used
by wxgui applications other than grc. This is a step in that direction.

You should be able to change the import statement and constructor, and
everything will work with the forms module.

Thanks for your Answer,

i changed from,
self._variable_text_box_0_control = grc_wxgui.text_box_control(
window=self.GetWin(),
callback=self.set_decim,
label=‘decim’,
value=self.usrp_source.decim_rate(),
)

to,
self._variable_text_box_0_control = grc_wxgui.forms.text_box(
window=self.GetWin(),
callback=self.set_decim,
label=‘decim’,
value=self.usrp_source.decim_rate(),
)

But this results in an error:
TypeError: init() got an unexpected keyword argument ‘window’

How should it look like now ?

After 3.2, this stuff will get merged in officially to wxgui, for now,
your on the bleeding edge!

Look at the source code to get the parameters:
http://gnuradio.org/trac/browser/gnuradio/trunk/grc/src/grc_gnuradio/wxgui/forms/forms.py

Or, generate a flow graph in grc with the various gui controls, and see
what parameters are used.

And there seems to be some more bugs:

Any Ideas ?

I still got some more errors:

self.Add(self._variable_chooser_filter)

And there seems to be some more bugs:
callback=self.set_gain_usrp_source,
^
SyntaxError: invalid syntax

Any Ideas ?
