QT GUI Push Button, QT GUI Toggle Switch, QT GUI LED Indicator, Logical problem

Thu, 30 Oct 2025 03:41:40 -0700 

Hello,

 

I'm using GnuRadio 3.11 on Ubunu 2025.10

and I run into a logical problem with

 

QT GUI Push Button

QT GUI Toggle Switch

QT GUI LED Indicator

 

I have configured in the LED Indicator block

  state = button | switch

 

With this configuration, the using behaviour

after startup is different for

  a) first button then switch (works fine)

but the sequence

  b) first switch then button (give me an error message)

 

I have isolate this in the flowgraph ButtonAndSwitchTest.grc

I need this to activate something steady or temporarly...

 

Is this a mistake from me?

It seems to be, a problem in the initialisation.

And is there a workaround for that?

 

Thanks
