Ok
There is no need to set stylesheet on radio buttons.
If you right click main window and select Change stylesheet
you can put all lines there
QRadioButton#radioButton_2::xxx
QRadioButton#radioButton_3::xxx
QRadioButton#radioButton_4::xxx

for the colors u want.

all of it. for all names. and the default one.

then its always in effect.

and then just
ui->radioButton->show()/hide()

how many leds will there be ?

@mrjj
thanks alot

there will be 3 or 4 groups and about 10 to 15 LED's in each group

@rezaMSLM
Ok, im a bit concerned about using names directly
ui->radioButton_2->show();
wont that become tons of names ?

[rezaMSLM]

@mrjj
yes it will
but i think this is the only way i can do

i'd like to use this LED indicator but dont know how put LED's in the coordinates i want to

LED example

[mrjj]

@rezaMSLM
well its possible to do more generic.
sender()) or lambda

its just a widget like radio button so its almost the same.
however, there is no designer version so you have to new it and place it.
(or use promotion as i did )

those leds will be fixed ?
So you have no need to save and load the locations?

[rezaMSLM]

@mrjj
yes LED's are Fixed

[mrjj]

@rezaMSLM
ok so it will work pretty fine just placing them in designer.

in the sample

i use promotion. that allows you to copy them around and at run time they be the leds.

did u try sample?

did u try sample?

yes
but dont know how to put LED's on the places i want on map

[mrjj]

@rezaMSLM
you just copy the widget and place it where u want ?

the widget is the led. so it work the same as radio buttons.

@mrjj
I still don't understand how to put LED's on different places on the map

please explain more.
how to use promotion?

[mrjj]

@rezaMSLM
you put a widget on the form and right click it
select Promote
then give it the class name and include

Then click Add
and then promote.
When run, its now a Led.
you must have ledIndicator.cpp and .h added to project
