How to keep ADS DockManager widgets equal width when dragging/dropping and programatic way?

[azarcoder]

I’m working with Qt Advanced Docking System (ADS) in my QMainWindow.
Currently, I can dock widgets side by side, but when I drag and drop a new widget next to another, the sizes are not equal — the new one just squeezes in.

What I want

• Whenever I place a new widget beside another (by drag & drop), all widgets in that splitter should automatically take equal width.

• For example, if I already have 2 widgets side by side and I drop a 3rd one, I want all three to resize to 1/3 each.

What I tried

• Using

ads::CDockManager::setConfigFlag(ads::CDockManager::EqualSplitOnInsertion, true);

but this only affects the insertion moment, not rebalancing when dragging around.

• Manually connecting to dockWidgetAdded and calling splitter->setSizes(...), but it doesn’t always cover user drag-and-drop repositioning.

Question

👉 How can I force equal splitter sizes automatically after a widget is dragged/dropped beside others in ADS DockManager?
Is there a signal or best practice for rebalancing splitter sizes every time the layout changes?
