[fpc-pascal] Synapse 37b4

[Lukas Gebauer]

FYI:

Has been published next Synapse snapshot 'synasnap 37b4' with lot of 
annonced changes for better FreePascal support.

You can use Synapse for all unix based targets now, but it is totally 
untested now! (we have reported some success on MacOsX only)

[fpc-pascal] SSE3

[Pianoman]

Hi, I am interested whether is planed implementation of SSE3 floating 
instruction in to FPC. I saw optimizations in gpc for p2 p3 how can I set 
FPC to optimize let's say for P4?

Regards
Pianoman

I use something like

var a: array of byte;
setlength(a,TheSize);
blockwrite(afile,a[0],TheSize);

Of course, if it is possible that TheSize=0, I have to write "if TheSize>0 
then blockwrite(...);"


Is this the intended way? (Ok, that's not a big overhead, but it seems 
strange to me.)


What is the intended way (if it's somewhat different)?

Hi,
I think it's off-topic, but since I don't know where to look I take a
chance asking here in the hope that some GTK-gurus can help me further.
I'm making a gtk2 application. Since it has to run on an arm-box with a
320x240 screen I made a main form of that size (actually 320x220 because
the title bar). This displays fine, full screen. On that form I have a
button to show a modal form, defined with the same size. When I display
this modal form on my i386-PC I get what I expected : a window of the
same size as the main window. When I display this on my arm-box it's
smaller and some buttons are clipped away.
I would like to understand why this happens. I could trim the form by
trail and error to fit it in the place I get, but this is not good enough.
I don't know how I could google for this, if it's possible. I looked
around on the gtk.org site without luck.
Is there anyone who can point me in the right direction ?
Regards,
Koenraad Lelong.

Re: [fpc-pascal] Typecasting by accident

[Flávio Etrusco]

I stand corrected. I've checked Delphi5 today and none of my
expectations where correct :-(
Of course I think that AnsiString being a native type would require
that (one) typecast just like any other (native type).

Of course I also think that any object should be cast to a mininum
common ancestor before being cast to any other class, but maybe it's
just me ;-)

It doesn't.

No. {$t+} only influences implicit pointer conversions.
