Hello,
I have a strange issue in my plugins GUI beatslash-lv2
(https://github.com/blablack/beatslash-lv2) or deteriorate-lv2
(https://github.com/blablack/deteriorate-lv2).
The GUI widgets to control the plugins gets disconnected when used for a while.
I can reproduce the issue in Ingen almost everytime, although I never
know exact when the GUI will disconnect and Ingen doesn't output any
error.
What happens is that once the widgets disconnect, if I try to change
the values via the GUI (turn the dial, change the value of a combo
box, etc) the changes are not transferred to the LV2 DSP.
The way I connect the GUI values to the LV2 values is as follows:
m_comboWaveForm->signal_changed().connect(compose(bind<0>
(mem_fun(*this, &Vco2GUI::write_control), p_waveForm),
mem_fun(*m_comboWaveForm, &ComboBoxText::get_active_row_number)));
where m_comboWaveForm is of type Gtk::ComboBoxText*
Even if I close the GUI and reopen it, the signals won't reconnect.
I'm not sure where the issues is (GTK, LVTK.....or my code!).
Is there a better way to connect signals in such design?
Thanks in advance for the help.
Aurélien

Have you confirmed this issue in a different host as well?
There is a lot of stuff going on between your UI and the plugin
instance, especially in a client-server host like Ingen. Do you mean
your widgets are not receiving events whatsoever, as verified *in the UI
alone*, or they aren't getting all the way to the plugin instance?
The former problem is much smaller in scope. The problem may not be
related to your code or Gtk signals at all.

No, but I haven't used beatslash-lv2, ams-lv2 or deteriorate-lv2 anywhere
else but Ingen.
When the issue happens, all plugins running from these 3 sets are impacted,
but other plugins are still working fine.
That's why I assumed the issue was with my plugins...

I'm not sure I understand exactly what you mean.
Vales changes in the GUI are not received by the DSP, and (if I remember
well) changes on the DSP front (via Ingen internally created GUI) are not
received by the GUI.
The problem is that the issue happens randomly. I spent all afternoon
trying to reproduce it and it never happened. But the days it happens, I'm
always in the mid of something else to do proper testing (creating videos
or actually playing music!)
