Yes I have noticed the current panel index in the ressources, the selction works, but when I drop a widget on the selected panel and test the UI, the widget float over all and is not set on the panel i have selected.
I have checked that when I begin from the New Window Style > Config window wizard which creates 3 tabs (General/tab2/tab3) this way to edit works. BUT when I change the tab labels every things I have previouly edited on the individual panels becomes overfloating. ANYWAY when I start from a new PtPanelGroup this not works at all.
Should I add some link information, at editing time, somewhere ?
You need to put the widget into the Pane you added to the panel group. Sounds like you are actually getting the widget as a sibling to the panel group rather then a child of one of the panes. Check the Widget Tree inside of PhaB.
Ok I ve found the error, I was editing the PtPanelGroup Panel Titles ressource to set tabs name, instead of giving individual Title to each PtPane Title, and it was doing this strange behaviour.
