Great, thanks a lot!

 I tried it with GIMP 2.6.4, it worked but we need to create a new
 image first before the menu become active, otherwise the menu is
 disabled. Also the file open dialog appeared behind the image window.

I tried it with GIMP 2.4.5: Here, the dialog opens nicely in front of
the image window, and the WinOpen menu option is available if an image
is open OR gimp has just been started (i.e. it's only disabled if an
image has been opened and closed).

So, it works perfecly fine for me. :-)

 At least the first issue can easily be addressed. The plug-in should use
 the empty string as image-type parameter in the procedure
 registration. It probably uses * which means activate this plug-in if
 there's an image, no matter what image type.

Thanks. The source code is not included in the above download link,
but there's a text file containing the author's contact info, so if
anyone is interested in taking over maintainance of that plug-in, it
shouldn't be difficult to get the source (might be easier than
starting from scratch).

Heinzi

The problem is not that any particular user (you) does not eject disks

 This is a case of the OS fostering bad habits by treating the users

Well, apparently most of the users *were* idiots unable to learn

 Windows 2000 did that. Users were not happy.

No, that is because your operating system of choice sucks at file I/O.
Windows does not buffer access to flash and network drives. So an
application writing a file with lots of file I/O calls will get
miserable performance for slow drives. Copying the complete file to that
drive will transfer the data in much larger blocks and thus yield
reasonable performance. This is not the case on Linux for example. There
the operating system will take care of combining many small file I/O
operations into large buffer accesses.

We might be able to work around this limitation by porting the XCF load
and save routines and all file plug-ins to GIO, the VFS API that was
recently added to GLib. Then we could use a GBufferedOutputStream which
would do the buffering at the application level.

using undocumented OS features to make their applications more

your effort on motivating people to improve GTK. And I don't want to

I personally find the GTK+ widget so bad compared to the native Windows one
that I usually resort to dragging images from Explorer when I want them
opened in GIMP (and I don't use Explorer for file management, but my usual
file manager works in console and thus doesn't support drag and drop).

[Gimp-user] Win32: Use standard Windows File Open/Save dialog

2009-01-03 Thread Heinrich Moser
Hi!

Short question:

Is it possible to make GIMP use the default Windows File Open/Save
dialog*, for example, by setting some secret configuration option? I
remember that there was a plug-in for this a long time ago (which
added Windows Open and Windows Save As menu options) but I cannot
find that anymore.


Long explanation (i.e. why would I want this):

The reason that I want this is because the GIMP dialogs are terribly
slow when accessing a slow (e.g. VPN) UNC network path (=
\\IP-Address\Share\directory\...). For comparison: After choosing a
directory, GIMP takes ~20-40 seconds before showing the contents (the
dialog being unresponsive during that time). On the other hand,
Thunderbird (to use another multi-platform open-source product for
comparison) pops up the default Vista file save dialog, which shows
the directory contents almost instantly.

I'm not sure if this is a GIMP bug or not; it's quite possible that
Microsoft is doing some behind-the-scenes magic here (caching,
undocumented functions, whatever) that causes it to be a whole lot
faster than any other custom-made file chooser implementation. I'm
using a workaround currently (putting the network directory in
offline mode before using GIMP, which causes the UNC share to be
redirected to a local cache directory; and synchronizing afterwards),
but I really wish I wouldn't have to.

Greetings, TIA,
Heinzi

* e.g. by using the GetOpenFileName/GetSaveFileName API functions

There seems to be a NIH syndrome in many programs, Gimp included,
where the devs feel (possibly rightly in many cases) that they must
reimplement core OS functionality. File Chooser dialogs are among the
most visible (and annoying) of these cases. Although you use Windows,
here is my Kubuntu bug about the situation:

 No. And we are certainly not willing to add such an option.

OK, thanks for the information. In that case, I can just hope that
such a plug-in turns up again somewhere.

 The reason that I want this is because the GIMP dialogs are terribly
 slow when accessing a slow (e.g. VPN) UNC network path (=
 \\IP-Address\Share\directory\...).

 You should report this as a bug against GTK+ then and perhaps you will
 also want to help the GTK+ developers to isolate and fix the cause for
 this.

Thanks for the pointer into the direction of GTK. To verify this, I've
just downloaded gedit. It seems to use the same file open dialog
library (except for the preview), but, surprisingly, it is indeed
faster than GIMP (~10 seconds to show the directory contents, as
compared to ~30 with GIMP).

[Gimp-user] Win32: Use standard Windows File Open/Save dialog

2009-01-03 Thread Richard H.
I understand why it is the way it is, which is why I mention that it
is sometimes the 'right' decision. However, end users don't like it,
no matter what the technical merits may be. Also, each application
obviously has it's own special needs, and the OS default File Chooser
cannot satisfy them all.

Maybe the GTK library (GtkFileChooser, to be specific) could show the native
Windows dialog, if available?

One standardised file chooser can't satify all needs, but a solution is that
there are hooks and other mechanisms that allow applications to extend the
file chooser.

However this should be discussed in a GTK forum/mailing list.

  No. And we are certainly not willing to add such an option.
 
 OK, thanks for the information. In that case, I can just hope that
 such a plug-in turns up again somewhere.

You can easily write such a plug-in yourself, in case there's really no
way to locate the old one. It should be a trivial plug-in to write for
someone who knows the Windows file-chooser API.

  You should report this as a bug against GTK+ then and perhaps you will
  also want to help the GTK+ developers to isolate and fix the cause for
  this.
 
 Thanks for the pointer into the direction of GTK. To verify this, I've
 just downloaded gedit. It seems to use the same file open dialog
 library (except for the preview), but, surprisingly, it is indeed
 faster than GIMP (~10 seconds to show the directory contents, as
 compared to ~30 with GIMP).

You should investigate this then. It seems rather unlikely that GIMP is
doing something with the file-chooser that could be responsible for
this. What GTK+ version are you using with GIMP and which with gedit?

Re: [Gimp-user] Win32: Use standard Windows File Open/Save dialog

2009-01-03 Thread Elwin Estle
I wonder if a problem I have had with saving files from Gimp in Windows is 
somehow related.  If I save direct to the local hard drive, there isn't much of 
a problem.  But if I try to save to say, a flash drive plugged into the same 
computer running Gimp, or to a network drive, then file save times get really 
long.  Yes, you expect those two situations to take a bit longer, but not that 
long.  I can save an .xcf file to the local drive and then transfer it to a 
flash drive or a network drive and it is loads faster than trying to save 
directly from Gimp. (which is what I typically do, save first to the local hard 
drive, then transfer the file to the drive I actually want to store the file 
on.)
