Hello,
Reviving a dead thread here, but I am experiencing what seems to be the same issue. I have a Docked Window with a tab strip inside that I would like to have centered and spanning the width of the application window in the North position. I followed the tips you posted in this thread Docked Window Size not correct on Client with Vision - Ignition - Inductive Automation Forum, anchoring the group to the left and right instead of top and bottom and ensuring the components within the group are set to relative. I included two dummy labels to show that the spanning is working correctly for other components, but not tab strip components.
The running client for the below screenshot is a maximized window on a 1920x1080 monitor, and the labels have stretched to the full length of the window while being "centered", but the tab strip is left aligned.
Is this because the tab strip component is by default left-aligned? If so, is there a nifty scripting function I could use to change this?
Hopefully this gives a little more of what you are looking for, thank you.
