When I open Lazarus by clicking on an .lpi file, why does a "Source
Editor (2)" window pop up on occasion?

Not sure what exactly happens for you. But here si what should happen.

You can open the same unit/file in several (synchronized) editors. If
you do this and close the project with more than one editor open, then
this is sawed to the session.

If you open a project that has such a session (a project you saved, or
maybe a project some one else saved), then this is restored.

Thanks, Martin.

I know that if I open several files, they will be visible as tabs
across the top of the editor window.

I didn't know I could open several editors.  I'll watch out for that.

Thanks, again!

Right click any of the tabs there are 2 entries:
"Move to new window"
"Clone to new window"

The 2nd means that the file will be open in 2 (or more) editors at the
same time. Changes made in any one editor will appear in all open
copies.


You can also assign this to key shortcuts.

Once a 2nd window is open, tabs can be dragged and dropped.

Thanks for the info.

It brings to mind a question, though:  Why would you open more editor
windows if changes that you make in one are visible in all of the
other open copies?

There are doubtless many reasons.
One is so that you can have part of the unit source (say a complex
class declaration) always visible for reference without having to
scroll to and fro in the editor where you are currently writing.

Firs of all, changes must be in all, otherwise, if I modified one part
in the 1sh window, and another part in the 2nd window, then when I
save each of them the 2nd save overwrites changes from the 1st.

Why would I open several windows?

So I can scroll them to different locations. If I work on big files,
then I often need to see several locations in the same file.

This also applies to seeing 2 different files side by side.

Fair enough!

Thank you, gentlemen!
