multiple models for poolmotor in taurusgui

[dschick]

Hi, I am trying to add a Sardana poolmotor panel to my taurus gui which works perfectly fine for a single motor/model.
The poolmotor itself also works fine with multiple motors/models when started from the command line.
But when trying to add multiple motors/models to the poolmotor panel in taurus gui it just not works and shows some wired panel instead with the following warning:

MainThread     WARNING  2020-09-09 08:53:32,813 PoolMotorTV: Exception caught while setting model: TaurusException("Invalid Tango device name 'tango://ampere.sxr.lab:10000/motor/mbitangomotorctrl/0, tango://ampere.sxr.lab:10000/motor/mbitangomotorctrl/7'",)

This might be related to #1143

I just want to add, that the poolmotor panel also does not work after a restart of the taurus gui

Hi Daniel,
I can not reproduce this issue. What I do is:

1. Open TaurusGUI, in my case: taurus gui macrogui
2. Open "New panel..." dialog: Panels -> New panel
3. Select TaurusForm panel type and give it a name
4. In Advanced settings select 4 motors (model is compsed as following: tango://pc255.cells.es:10000/motor/motctrl04/1, tango://pc255.cells.es:10000/motor/motctrl04/2, tango://pc255.cells.es:10000/motor/motctrl04/3, tango://pc255.cells.es:10000/motor/motctrl04/4)
5. Finish

thanks for the quick reply.
For the TaurusForm it also works for me but I use the Other and use poolmotor out of the Sardana repo.
Therefor I have a symlink of the Sardana qtgui folder to my taurus gui folder.
I am not sure if this is the correct way of using the poolmotor widget in the taurus gui.

For the TaurusForm it also works for me but I use the Other and use poolmotor out of the Sardana repo.

I have tried it in this way and what I get is a bunch of floating widgets.

I am not sure if this is the correct way of using the poolmotor widget in the taurus gui.

I think the PoolMotorTV (TaurusValue sub-class) is only foreseen to be used within a TaurusForm. Maybe one could try to use it in another widget with a grid layout, but this was not the idea behind its original design.

Is it in some sense not what you expect, or not convenient way of using it?

I confirm that.

TaurusValue and its descendents are "weird" widgets that mess with the parent layout. They should only be used within a TaurusForm, and only by letting the TaurusForm creating and inserting them.
If you want to force the use of a specific item class (such as PoolMotorTV) in a taurus form , have a look at the ItemFactory API

I just use PoolMotor without TV and then it is not floating around. For the +TV widget I confirm the floating behaviour
