Well, that will be an exciting update from SVN...
Frames. GTK2 (still use GTK 1)...

Does this mean that GTK 1 will not be maintained anymore ?

Probably in practice: yes ?

Does that mean the Editor speed issues has been resolved? Last time I tried Lazarus+GTK2 the editor did not feel nearly as fast as in GTK1. This was about a month or two ago.

If all is sorted, congrats to all that helped to finally get the GTK2 widgetset up to scratch!

Don't know. I think i'll keep using it for a while.

Thanks to all you.

Zitat von Graeme Geldenhuys :

The speed of gtk1 and 2 differ widely. On some platforms the gtk2 is even faster than gtk1. It depends on your window manager, video driver and the gtk2 version. AFAIR gtk 2.12 fixed some issues.

If all is sorted, congrats to all that helped to finally get the GTK2 widgetset up to scratch!

Not all is sorted. That's why 0.9.26 is using gtk1.

Mattias

Zitat von Michael Van Canneyt :

0.9.28 will still support gtk1, but gtk2 will be the default.

Probably in practice: yes ?

In practice it depends on the community.

Mattias

Zitat von "Coppola Ing. Salvatore" :

SetDesignInstance was introduced with fpc 2.2.1 and is needed for designtime Frames (the mail thread subject is misleading).

Can you use fpc 2.2.2?

Mattias

It's OK, :-)
thanks a lot!

Luckily my Ubuntu 7.10 has 2.12.xx. So I'll get an update now (at home) and give it a spin in GTK2. Oh no! That means I have to recreate the Raize font again. :-) I've been postponing this for ages, because to a lot of effort. Before I manually drew all Raize characters in FontForge so I could generate bitmap fonts for linux GTK1. Now I'll have to try and make truetype fonts for GTK2.

try the "terminus" font, i use it for everything source related (and terminal) since it's very clean and easy on the eyes. you'll have to `apt-get install console-terminus xfonts-terminus`.

I'll give it a try, but I really like Raize. :-) Old habbits die hard.

BTW:
Did you see the example custom theme an screenshot I posted in fpGUI newsgroup. A quick and dirty theme (without using images), that kinda gives the look you were going for. I was bored in my lunch break. :-)

I just got a svn update and couldn't compile Lazarus with FPC 2.2.0. I got an error which indicates i need a newer FPC version.

class procedure TSetDesigningComponent.SetDesignInstanceOfComponent(
  AComponent: TComponent; Value: Boolean);
begin
  // requires fpc >= 2.2.1
  TSetDesigningComponent(AComponent).SetDesignInstance(Value);
end;

So what is the minimum required FPC version? 2.2.1 (is that still around) or 2.2.2 (I believe the latest stable release) or 2.2.3? I'm get an update to FPC_trunk, so hopefully that would suffice.

2.2.2+

Thanks... I thought it would help others as well. I just compiled Lazarus (svn) with FPC (svn 2.3.1) and it's worked perfectly. :-)

To everyone who might experience Gtk2 speed issues:

Here are the possible reasons for slowdowns and some personal observations...

1. Video card drivers make a big difference. Proprietary ATI and Nvidia drivers are very bad at some 2d operations, while the OSS reverse-engineered counterparts usually are "consistently" slower on each operation, but faster globally. E.g: my total time for OSS gtkperf (see below) test with OSS reverse engineered ati driver was less than the proprietary one, even if all but one tests were slower. This one test took ~0.5s with the OSS driver, but 50s with the proprietary one (canvas ellipse drawing)

2. Gtk+ version can cause differences in performance, newer are better

3. UTF-8 bugs can cause slowdowns in editor (see if you don't get gtk criticals with utf-8 errors)

4. Some themes are much slower in Gtk2, some are outright bugged. There was a page with tests for this but I lost it :(

To test what causes your slowness get GtkPerf from http://gtkperf.sourceforge.net/ and install it (compile AND install). We can post our results somewhere on the forums or such to identify culprits. Try out different themes too and see the impact.

I'm using a customized Crux theme with special border theme (kind of Next/Apple-ish) and the proprietary ATI driver. Text draw and custom canvas draw speed suffers because of the driver, but otherwise I get very nice performance, even with Gtk2 lazarus editor (less than 100% cpu while scrolling by the line).

I hope this helps you fix some issues, and shows you that Gtk2 or LCL/gtk2 speed issues can be caused by things beyond our control.

i work in the english countryside, plenty of pubs here (there's 2 in the village). i sadly don't get to visit them that often (and the beer isn't that well kept in one of them :( )

Have you tried the misc-fixed font coming with most Linux distros? It's very similar to Raize, and it works just fine both with GTK1 and GTK2.
