How to send data from C++ to .UI file in Qt? - c++

Question

I'm currently making an embedded system using an ultrasonic sensor. In QT, I want to get data from the sensor, and send it to a .ui file. How can I send the data?
For example:
Sensor.cpp
int main(int argc, char **argv){
while(1)
unsigned int result = (high <<8) + low;
printf("Range : %u\n",result);
sleep(1)
}
mainwindow.ui
<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
<class>MainWindow</class>
<widget class="QMainWindow" name="MainWindow">
<property name="geometry">
<rect>
<x>0</x>
<y>0</y>
<width>800</width>
<height>600</height>
</rect>
</property>
<property name="windowTitle">
<string>MainWindow</string>
</property>
<widget class="QWidget" name="centralwidget">
<widget class="QTextBrowser" name="sensor_ourput">
<property name="geometry">
<rect>
<x>280</x>
<y>150</y>
<width>256</width>
<height>192</height>
</rect>
</property>
</widget>
</widget>
<widget class="QMenuBar" name="menubar">
<property name="geometry">
<rect>
<x>0</x>
<y>0</y>
<width>800</width>
<height>22</height>
</rect>
</property>
</widget>
<widget class="QStatusBar" name="statusbar"/>
</widget>
<resources/>
<connections/>
</ui>
I want to put the sensor data from result variable to sensor_ourput in mainwindow.ui.
