Use interfaces instead of objects.

There is no better way (yet).

[Lazarus] Aarch64 as CPU target for RPi3 with Linux as OS

[Alfred]

While preparing fpc(laz)up for my RPi3, I did encounter an error with 
Lazarus.


Choosing a64 as CPU target in Lazarus does not work on my system.
Manually (command line) choosing aarch64 as CPU target however, does 
work.


Am I doing something wrong ?--

steveg has Lubuntu with LXDE. I guess Raspbian also has LXDE. This may
be a LXDE related issue.
Please confirm.
Then you guys should find which revision broke it for LXDE or if it
was always broken.

Maybe that should wait a little. Ondrej is making a generic
configuration API for storing column widths of all IDE ListViews.
ProcedureList can use the same.

No, it was opened because forms could not be resized down from initial
size (see subject of thread) and it was NOT caused by constraints
being accidentally set (I have checked both in the IDE and in the form
file itself, there is none). This suggestion was done some way down
this thread, but was not the cause.

I added comment about revision in order to say what state my trunk
version is in. I was asked to do that here...
It has nothing to do with why this particular revision was created. I
just downloaded trunk today in order to check the solution to the
resizing issue that was purported to be done.
Either that fix is not part of that revision or the fix does not work.

Yep, fixed in r51790. I forgot that the design time needs special 
treatment. Thanks for reporting.

Hi Juha,

Thanks for reverting the previous change.

Yes, not a problem. I'll make a patch and submit it to Mantis. I'll also 
create a patch to "more officially" save/restore the column widths.


Regards,

And this is what I did too...
I got Lazarus using this command:
svn co http://svn.freepascal.org/svn/lazarus/trunk trunk

Result after building bigide:
The same sizing issue as before. Not possible to make window smaller
than the startup size. This includes the Lazarus IDE itself

Lazarus Help/About shows SVN rev 51768 but I don't know if this is for
FPC 3.0.0 or Lazarus trunk...
However Lazarus Release 1.6 shows SVN 51666 when I check it so I guess
51768 is the Lazarus revision.

Another observation (bug?):
I put a button on the empty form of the default project.
Then I doubleclicked it hoping to get to the OnClick event handler in
code editor (which normally will be created), but nothing at all
happened.

I had to go to Object Inspector in order to create the OnClick event.
Is this how it is supposed to work now?

Because it works as expected in release 1.6, one is brought to the
event handler when doubleclicking in the form.

Does this mean I should switch to Lazarus trunk (1.7.xxx) from release
to be able to fix this in my 1.6 release.
Or is there a simple patch I can apply to the release revision?

I guess I can make a test by checking out trunk and make a "Trunk"
Lazarus...

[Lazarus] catch TOpenGLContext exceptions

[Andrea Mauri]

Dear all,

I developed an application using TOpenGLcontext component in a form.
Some users have problems with opengl (especially on linux), missing 
libraries, FB config missing and so on.


Actually if the system on which my application is running has problems 
with opengl my app crashes.

e.g.:
"Could not find FB config"

I would like to catch these exceptions and if Topenglcontext cannot work 
I would like to disable it and run my app wihout it. The form with 
TOpenGLcontext can be used but it is not essential, my app can work 
without it losing few functionalities.


I tried creating the TOpenGLcontext at runtime (in try .. finally) but 
it does not work, I got an error and the app stop working.
I would like to test if TOpenGLcontext can be created, if not I would 
like to not create TOpenGLcontext but let my app running anyway.


Is it possible? How can I do that?

Thanks.
Andrea
