hi @SGaist . i was check it but this is so old. i using ros2 humble and my os is ubuntu 22.04. so we have any another choice or not? this is so important for me too use ros2 because my company use ros2

yes you can do this. You can do it without downloading the necessary QT_ROS plugins, it's all a link after all.
Which operating system will you try?
For linux OS start running Qt creator from terminal and write mandatory commands for ros.
Provide rosla communication with the help of Signal Slot

Did you check the ROS Qt Creator plugin documentation ?

In any case, that's something you should check with the ROS folks building that integration.
