Re: Building and packaging for Windows

Re: Building and packaging for Windows
GTK is usually already installed with GIMP; Presumably not everyone is interested in installing GIMP just to get a copy of GTK+. if not, the packages are on http://gimp-win.sourceforge.net/old.html That old should tell you that the versions there are already obsolete, and will become increasingly so. Nowadays the GIMP installer bundles the GTK+ runtime and dependencies, so it is not possible to find an installer for just a fresh GTK+ from the gimp-win site. (And even the GIMP 2.4.0 installer bundles GTK+ 2.10.14 and not the latest 2.12.1.) From a bundled GIMP + GTK+ + dependencies installation it can also be hard to understand what files belong to which part, and which are really needed for plain GTK+ apps. (For instance, the pangoft2 DLL and the freetype and fontconfig DLLs and configuration files are quite unneeded for plain GTK+ apps.) The main, some may even say official, distribution for prebuilt binaries of each version of GTK+ and dependencies is on ftp.gnome.org. (In the form of zip archives, from which it should be a small matter of scripting to construct installers if one likes.) --tml ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Print bug on Windows ?
I wrote a simple printing test that shows a probable GTK+ bug when run on
Windows OS.
Test draws one red rectangle over the page area.
When run on Linux, page preview looks good.
When run on Windows, rectangle does not fill entire area of the page (not
counting margins)!
I've checked if the problem could be due to larger margins, but that is not
it. It seems to be a bug.
Can anyone confirm this.
Screenshot of the correct Linux behaviour is at:
http://notecase.sourceforge.net/temp/printtest_ok.jpg
Screenshot of incorrect Windows behaviour is at:
http://notecase.sourceforge.net/temp/printtest_not_ok.jpg
(save to disk to properly view the big white area at the bottom of the page)
On Windows, I've tested with VS200 using GTK+ 2.10.11 from
http://gladewin32.sourceforge.net
Later I've updated this GTK to latest 2.12.1 using Tor's official Windows
build (http://www.gimp.org/~tml/gimp/win32).
Is this a Win32 port bug ?
Does anyone have the same problems ?

Miroslav

Re: Building and packaging for Windows
GTK is usually already installed with GIMP; Presumably not everyone is interested in installing GIMP just to get a copy of GTK+. Is there a better choice of bitmap graphic editor than GIMP? (I am just curious, not starting flamewar :-) Of course, there may be some people who are not at all interested in image editing, but it seems to me that this is a basic tool, alike vector editor (my choice is Inscape) and text editor (my choice is Notepad++). if not, the packages are on http://gimp-win.sourceforge.net/old.html That old should tell you that the versions there are already obsolete, and will become increasingly so. The old versions are good enough for my purposes. I do not use features newer than 2.6.10 because I got the impression that it is not possible to run the new versions also on Win98. Or am I wrong? Also I suppose that it is not possible to write applications which would in run-time decide, depending on GTK version, whether they can call new functions or not. It is so? Nowadays the GIMP installer bundles the GTK+ runtime and dependencies, so it is not possible to find an installer for just a fresh GTK+ from the gimp-win site. That is the reason why I use the old versions. The main, some may even say official, distribution for prebuilt binaries of each version of GTK+ and dependencies is on ftp.gnome.org. (In the form of zip archives, from which it should be a small matter of scripting to construct installers if one likes.) I only thougt that for those like me, with less skill and time, it would be helpful to know that there is also the quick and easy way with the old packages.

Thank you for the feedback. I think what you are suggesting is a way to
override the default style for a particular widget. I don't think this
achieves my primary goal, though, of avoiding the overhead incurred by
the logic in GTK that supports themes. This overhead includes acquiring
a lock and navigating/manipulating linked lists of styles. Use of a
profiler has shown this to be a significant burden to my application.
What I'm hoping to do is assign widgets a style that I can manipulate
directly and have GTK honor this. gtk_widget_set_style() looks
promising for this, but its associated comment states that it interacts
badly with themes. GTK changes the style a widget points to under the
sheets, and I don't what events cause it to do so.
I'm not a GTK hacker (probably obvious by now) so I may be going about
this very wrong. I'm hoping someone can point me in the right
direction.
Thanks!

Re: non-themed widget styles?
[EMAIL PROTECTED] wrote: I guess I don't understand what you're trying to do :-( What's the problem with the theme engine? Nothing except that the buttons I'm using basically have everything style-related set programmatically and attributes of their style (i.e., background and foreground colors) change rapidly. Therefore I'm asserting that any runtime support for configuration-based styles is a waste of CPU. Profiling has shown that this is contributing to a significant amount of CPU usage. Calls to gtk_widget_modify_style() cause a lot of stuff to happen, and I think much of it is in making themes (or maybe I should just say configuration-based styles) work nicely. What I want to do is tell a widget to be blue with minimal overhead. A style is still handy in that I still can benefit from having the widget's appearance change with its state. But I think most of what gtk_widget_modify_style() does is moot for how I'm using these particular widgets and so I'd like to avoid the overhead.

Telling a widget not to be in the focus chain
Hi!
I would like to tell a widget to not be part of Gtk's focus chain. I
know there is gtk_container_set_focus_chain, however, I would like to
keep Gtk's default focus chain logic and just would like to have one or
two widgets not being part of it. The widget could be a GtkButton,
GtkEntry, GtkTreeView or GtkTextView, or any other user interface
element.
I tried to unset the GTK_CAN_FOCUS flag. This works nicely e.g. for
GtkButton (pressing tab jumps over the button) but when doing this on a
GtkEntry or GtkTextView it means that the widget also doesn't grab the
focus when clicking on it, thus no text input is possible any more.
I tried g_signal_connect(widget, focus, G_CALLBACK(noFocus), NULL)
where the callback is defined as:
static gboolean noFocus(GtkWidget *widget)
{
g_signal_stop_emission_by_name(widget, focus);
return FALSE;
}
This works well for GtkButtons and GtkEntries but has a small glitch
for GtkTextView and GtkTreeView. There is no focus drawn but still the
focus is 'somehow on the widget'. Pressing the tab key again then
moves on to the next widget. Not perfect.
So, anybody has an idea what the correct way of leaving a widget out of
the focus chain is?
