Do you mean a selection that is dragged from top-left to bottom-right vs. one that is dragged from bottom-right to top-left? The borders are different colours, no?

[Fabián Inostroza (fabianinostroza)]

Yes, but it always selects anything that it's partially inside the selection box, no matter how the selection was started.

In Pcbnew, a top-left started selection only selects objects that are fully enclosed by the selection box. In eeschema the same action selects anything that intersects the selection box.

[Nick Østergaard (nickoe)]

I think the direction aware selection is only implemented in GAL. (I didn't check it right now, so maybe you need to be sure to be in GAL)

[Fabián Inostroza (fabianinostroza)]

Hi Nick

I'm using the new eeschema GAL, there is no option to use legacy in the master branch.

[John Beard (john-j-beard)]

I see this in the current master. Left-right selection is a yellow-edged box, right-left is a blue-edged box. However, they both have the behaviour Fabian reports: selection of anything inside OR intersected by it. This should be the behaviour of only the blue-edged right-to-left action.

[Jon Evans (craftyjon)]

This will come as part of porting Eeschema to the new tool framework (currently only the rendering code is ported to GAL, it is still not making use of the tool framework which is what is responsible for the nicer selection behavior in PcbNew)
