Updating a progress bar

dani98000

i am trying to do a progress bar from 0% to 100%
that will get my value from my temp sensor (i called it bufferSplit) and i want that the number 0 will be the minimum and the number 35 will be the maximum(100%)

This is for a project in my school
Thank you in advanced for the help =]

Hi
Please have slightly more patience before bumping a topic
as many users here are in other time zones - so give it a day. :)

QProgressbar has setMaximum() for setting upper limit.

If that is the actual question ?

@mrjj i mean that the progress bar will show 0 to 100% but the 100% is 35 celsius

Hi and welcome to devnet,

Then use QProgressBar::setRange
So basically:

myProgressBar->setRange(0, 35);

@SGaist where does it use the value from the temperature sensor?

SGaist

Once you have them, call setValue on the progress bar

@SGaist said:

QProgressBar::setRange

what do you mean?
im sorry for all the questions im new to this
the temp for the sensor is called buffersplit
so can you please tell me the code that i should do?

SGaist

I mean that if you know that the temperature is between 0 and 35 then you can already set the minimum and maximum value of the progress bar.

What is buffersplit exactly ? A variable containing an integer value ?

dani98000

@SGaist yes

SGaist

Well, when buffersplit call setValue(buffersplit) on your progress bar.

I'd recommend using a more descriptive variable name
