How to disable automatic hilights, but keep mouse Detection


I would like to use the mouse-detection capabilities of an AIS_InteractiveContext without active Highlighting.
My goal is to group individual objects (lines, points, planes and shapes) to 'Assemblies' of which all contained objects should be highlighted once a member-object has been detected under at the current mouseposition (set with moveTo).

My problem is that I need to disable auto-highlighting to prevent it form interfereing with my own highligting, but I don't seem to be able to switch of the Auto-Highlighting without disabling detection as well.
(And for AIS_Lines, even disabling does not work.)

I tried to switch of auto-hilighting - which didn't work. Then i researched the forum only to find that others had the same problems. Someone suggested the solution to set an undefined hilightmode. This _did_ deactivate automatic highlightimg (except for AIS_Line), but it also deactivated Detection.

So, I am pretty much stuck.
Has anyone of You experienced similar probelms, or has a hint for me?

Best regards

myAISContext->Hilight(myAISContext->DetectedInteractive(), true).

Thank you,

That's the way I already tried.
This way it is supposed to work, but it doesn't:

Hilighting my objects manually does work, but setAutomaticHighlight does not show any effect.
Objects are still Highlighted if they are touched by the mouse pointer.

If you only need detection of AIS object, you might want to use the Pick method from the selector (this is what is done by the MoveTo method from AIS_InteractiveContext) and handle everything yourself (look at the source code in AIS_InteractiveContext_1.cxx / MoveTo method). It's pretty straightforward, you use the selector from AIS_InteractiveContext::MainSelector() like it's done in the MoveTo method (selector->Pick(XPix, YPix, aView)) and you iterate over detected objects and do what you want with them.

Good Luck,

Thanks a lot, that approach works like a charm!
