[Discuss-gnuradio] QT GUI Entry Block issue

[John Makous]

This is a final follow-up to my recent posts regarding the failure of the
QT GUI Entry block to work properly in Gnuradio. The problem occurs if I
use Gnuradio 3.7.11, which is what Ubuntu installed on my new machine.  I
ran a test on a machine running Gnuradio 3.7.12, and there was no issue
with the Entry block not working properly; it worked fine.

So,apparently this is an issue with Gnuradio 3.7.11, which, unfortunately,
is currently the version that Ubuntu installs. I will need to install Gnuradio
3.7.12 or .13 using Pybombs if I can. Hopefully Ubuntu will update the
version of Gnuradio that it installs.

My OS is Ubuntu 18.04 LTS, and I am using Python 2.7.15.

I have attached a very simple .grc program that illustrates the 
problem. The program consists of a cosine signal source feeding into a 
QT GUI Time Sink. The frequency of the signal is controlled by a QT 
GUI Entry block. Trying to change the frequency while the program is 
running will cause a crash.


Anyone familiar with this problem?

Thanks!

I don't see this issue at all on my system.

What OS version are you using?  What version of Python?

[Discuss-gnuradio] QT GUI Entry Block issue

[John Makous]

This is a follow up to my previous post. I got the entry block to work by
deleting the .toAscii() at the end of the code in line 23 of the
gtgui_entry.xml file on my computer:

lambda:
self.set_$(id)($(type.conv)(str(self._$(id)_line_edit.text.toAscii()()

After changing this .xml file, I was able to run the test file I created
and change the frequency without the system crashing, and the frequency
changed as expected.

I am wondering if this is all there is to this problem, or if there is
something deeper going on. Would this fix work universally for everyone?

[Discuss-gnuradio] QT GUI Entry block issue

[John Makous]

I am trying to use the QT GUI Entry block to change variables while a
program is running. However, I have discovered that when I change the
variable defined by the Entry block, the program crashes, displaying the
error: AttributeError: 'unicode' object has no attribute 'toAscii'  I am
running GNU Radio Companion 3.7.11.

I have attached a very simple .grc program that illustrates the problem.
The program consists of a cosine signal source feeding into a QT GUI Time
Sink. The frequency of the signal is controlled by a QT GUI Entry block.
Trying to change the frequency while the program is running will cause a
crash.

Anyone familiar with this problem?

Thanks!
