you it did not understand, reads:

Panel1.enabled:=False:
In Delphi, the components it does not intervene with the colors. In
Lazarus, the components of inside they had been transformed for the
gray.

Example: Checkbox inside of the TPanel (in Delphi) continued with its
property color without alteration.
in Lazarus became gray.

then

t has how create transparent TPanel? how?

user can see the colors of the components, but he cannot have access.

I not speak english, sorry.

What has enabled or not enabled to do with transparency?

It's quite useful that components get grey - that gives the user a
hint that they're disabled. In Delphi, he wouldn't know and get
confused.

Do you want components to be colered but not enabled? That would be
quite against the improved userfriendlyness of Lazarus  And it has
nothing to do with transparency - transparency is for showing what's
below, but the panel is below the controls, it's not above them. The
controls are greyed because they're disabled, so the greying is
probably in the controls, and not in the panel at all.

Calm! - I have a project. - student of a school go answer with one X.
- After click, controls must be incapacitated, but the colors must to
be without gray in the controls.

I go to use green (true) and red (false) and the student cannot
clicked with mouse

OK,
What CCRDude told is IMO the correct behaviour. When controls are
disabled, they get grey. And indeed, delphi doesn't do that, and from
a UI design pov. it is annoying/confusing. The user cannot see that it
cannot click items. So you wonder what is going on. For a good design
you have to desable all controls as well. IMO the delphi behaviour is
anoying.

Now back to your problem. You want to keep the colors but the user
cannot click them anymore (how do you give the feedback ?)
What you could do is in the onclick event check a boolean if the user
is allowed to click, and if not, simple exit the event.

In this case you can also use a checkbox without text and put a label
next to it.
Then disable (or hide ?)  the checkboxes.

This that I made. CheckBox without text and put a label next to it.
