I need to set the anchors for a TPairSliter.
I cannot click the splitter in the form editor.
The Anchor editor cannot be called from the popup menu ot the
components editor 
Is there another way to call the AnchorEditor for TPairSliter?

Hi,

To use the anchor editor for the PairSplitter in the form editor, you
have to click on the central dots of the splitter with the right mouse
button

The splitter in PairSplitter is intentionally not selectable.

Why would you need to change anchors for/to it?
You should use the 2 SplitterSides instead.

Or use a normal TSplitter.


I haven't checked the code, but in general controls like TPairSplitter
do their own setup for embedded controls. They don't expect user
interference, and they likely wouldn't work if there was.

...
The outer shape of the PairSplitter is a rectangle. It has to be
located somewhere on the form.
Since it has Left and Top properties, it might need anchoring, like in
my case.

Sorry, I misread. I thought you want the actual (internal) splitter,
not the entire component.

You can always select components from the treeview in the OI (just
don't hide that).

Yes, I can select it, but there is no Anchor Editor in the pop-up
menu.
But it occurs that after I open the Anchor Editor and click on a
component in the Object Inspector, the Anchor Editor changes the
edited component to the clicked one.

Ok, I concluded from my workflow....

If you select the "Anchors" property in the grid below => then it will
show an ... ellipses button => Press that, and the anchor editor will
open (for that control).

Once the anchor editor is open, you can just select other controls,
and it follows.

It would be really useful in the context menu of the Component Tree.
There is already a draft patch for this on the bug tracker.
