Re: GTK Install Problem (..Xft backend is required)
Hi, Tim Johnson [EMAIL PROTECTED] writes: there is no explicit information on _how to_ compile Xft with pango.

Re: stopping signals
Hi, dave walters [EMAIL PROTECTED] writes: I have a spin button with a callback function invoked by the value_changed signal. The callback func has a gtk_spin_button_set_value(). When this executes it causes the spinner to emit the value_changed' signal which invokes the callback which executes set_value() etc. It's recursive. I tried using g_signal_stop_emission_by_name() put in before the set_value() but it didn't work. Any ideas?? I don't understand the reason for this particular callback construct but since in general user interface elements often need to be updated from callback functions and the recursiveness you describe is causing problems for GObject newbies, here's how to solve this problem: Either block the value_changed signal handler using g_signal_handlers_block_by_func() before you set the value and unblock it later or compare the set value with the new one and only set the value if the two differ.

Hi, Roger Leigh [EMAIL PROTECTED] writes: This might be OT, but I would inherit from Gtk::Dialog, and provide get_foo() methods to get at my data. Mixing the user interface with the actual code seems to be a bad design choice. The dialog should be a view on the data not providing the data. So you should connect to the signals that indicate that the user changed data in the view and update your model accordingly.

Re: why is gtk install so difficult?
Hi, Steve Grimaud [EMAIL PROTECTED] writes: I'm sorry, but the statement below by Reuben hits the nail on the head for the user. The user doesn't compile any packages. Perhaps the user installs a binary package from time to time but actually she shouldn't even have to bother with that. Sven's answer (also quoted below) assumes several things that just aren't likely to happen unless you're advanced in the use of Linux and in building and installing software packages. I read the docs and followed the steps for pointing to what I believed were the right locations. I wonder why I should have to understand how the compiler and linker work in order to install a program. You don't need to understand how they work but you should have understood where the compiler and linker look for include files and libraries. This involves understanding the basics of gcc and ld command-line options (and on Linux it also involves a basic understanding of ldconfig). This is basic knowledge for building software. You can hardly get away witout this knowledge and if you are not willing to learn this stuff, you simply should not try to install software from source. Fortunately the Linux user nowadays can happily live without having to know all this since she will never have to compile from source. If it is easy enough to understand from a hundred lines of text or so, where are those lines of code? I pointed you to them in my mail. If Linux and these install and configuration packages are so powereful, the how in the world can a program not find files that I can find with a minimal comprehension of linux commands? The point is that there can be multiple versions of these files on your disk. It's very common practise to have multiple build environments on the same system. The configure script can hardly guess what build environment it is supposed to use. That's why you have to setup your build environment by setting a handful of environment variables before you run configure. Earlier in this thread people pointed out scripts that ease this task. People, are you actually realizing that building from source has become so much easier since pkg-config was introduced? While earlier each and every library installed their own foo-config file, there is now a common database of installed packages that has all this knowledge. All you need to do is to set a single environment variable correctly. Sven ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
Re: why is gtk install so difficult?
Hi, Ruben Safir Secretary NYLXS [EMAIL PROTECTED] writes: While it might be tedious to have a properly working autoconf test, it is what is needed for a sane installation of the source. You obviously missed the cause of this particular problem. Of course what you state here is correct in general. BTW - this problem is not just with gtk, but with gnome as well. Nothing is more fustrating than being told by a gtk application that lib xyz doesn't exist, when you can see the library in plain sight on the file system. IMO this is solely a problem of people not reading the docs. Building GTK+ (and probably most if not all GNOME applications) is straight-forward if you know a handful of rules. Basically you will need to know how your compiler looks for include files and how your linker looks for libraries. Then you should know how to change these behaviours and what role pkg-config is playing in this game. All this can be explained in full detail in about hundred lines. If people would look at the file INSTALL, they would notice a link to a webpage as well as a pointer to a local file which does just that.

Re: Setting fixed-width font
Hi, Peter Krueger [EMAIL PROTECTED] writes: This will completely override the old font attributes. If you only want to change the font from Helvetica or whatever it is to Fixed and keep the other attributes (style and font size) but you don't already know them, this is a bit more complicated. I never tried it, but I think something like this could work: First you must get the current PangoFontDescription from the widget's style. Then get the description string for it ( char* pango_font_description_to_string(const PangoFontDescription *desc); ) and exchange the font name with Fixed. When you got that you can create a new PangoFontDescription and modify the widget as explained above. You don't need to create a string representation of the font description and fiddle with it since you can modify the font description using the provided Pango API: http://developer.gnome.org/doc/API/2.0/pango/pango-Fonts.html Basically you call pango_font_description_set_family (font_desc, monospace); Note that monospace is the preferred alias to use for a font with fixed glyph widths. Which font is choosen depends on the user's font configuration then. Any correct fontconfig installation is supposed to provide at least one font for each of the sans serif and monospace aliases.

I am no expert on fonts. I work mostly in arial, and I immediately noticed that the font seems to look less sharp than it did before I upgraded. The difference was immediately obvious in the newsreader Pan, where I had previously been using arial 12, which now looked bigger and much fuzzier than before. It helps to reduce the size to 11 (which previously would have been too small and is now quite legible), but the poorer quality (to my eye), of the rendering remains. Is there a reason for this? Am I doing something wrong? GTK+-2.2 by default uses Xft2 to render antialiased fonts while GTK+-2.0 defaulted to the old-fashioned X11 core fonts. If you really don't like the new font rendering, you can set the environment variable GDK_USE_XFT to 0. But you should be aware that the old server-side font rendering will not stay forever, it is likely not to be supported with future releases of Pango. You can improve the text rendering by using an uptodate version of freetype2. Also, enabling the truetype bytecode interpreter in freetype2 improves the legibility of small fonts.

Re: newbie: doubt on GObject system
Hi, Tarun Ramakrishna Elankath [EMAIL PROTECTED] writes: I am new to Gtk and have been reading up on GObject and GType. What I have failed to understand is why is it that the GTypeInfo structure fails to provide a field for instance finalizer functions ? We have fields for specifying class initialization, class finalization, instance initialization functions but *not* for instance finalization. For specifying an instance finalization function, one needs to assign it to the finalize member of the GObjectClass in the instance init function. And in addition, make sure that this user-defined finalization function also calls the finalize function of the parent class object. Is this the only way to do it ? Have I misunderstood something here ? I think you understood the principles pretty well. Well, most people assign the finalize method when the class is initialized, not in the instance initializer.

Re: trying to build gtk+-2.2.1 - error when running configure
Hi, Luong, Natalie N [EMAIL PROTECTED] writes: I ran ./configure, and I get the following error (as recorded in the config.log): configure:12889: checking for gdk-pixbuf-csource configure:12920: result: no configure:12928: error: Could not find a gdk-pixbuf-csource in your PATH How do I fix this? Looks as if you are cross-compiling. You need gdk-pixbuf-csource on the build host. It is installed with gtk+, so the easiest solution is probably to install gtk+ on the build host.

Re: Speed of GtkListStore additions O(n^2)?
Hi, Linus Walleij [EMAIL PROTECTED] writes: Then I happen to need to blank the store and refill it repeatedly. And there doesn't seem to be a good way to turn sorting _off_ once you turned it on, so any subsequent fills will be O(n^2) anyway. Any suggestions? Or will I simply have to destroy the ListStore (and thus the ListView) and create a new one each time I want to do something like this? What we are doing in gimp (plug-ins/dbbrowser/dbbrowser_utils.c) is the following: dbbrowser-store = gtk_list_store_new (2, G_TYPE_STRING, G_TYPE_STRING); gtk_tree_view_set_model (GTK_TREE_VIEW (dbbrowser-tv), GTK_TREE_MODEL (dbbrowser-store)); g_object_unref (dbbrowser-store); /* fill the store */ gtk_tree_sortable_set_sort_column_id (GTK_TREE_SORTABLE (dbbrowser-store), 0, GTK_SORT_ASCENDING); The views keeps alive and the new store is filled reasonably fast and sorted afterwards.

Re: Transparent buttons
Hi, Paul Davis [EMAIL PROTECTED] writes: On Tue, 2003-05-27 at 18:51, sydney barrow wrote: Is there a way to create transparent buttons (so that the background pixmap shows through) in GTK+ (1.2)? Any help would be greatly appreciated. IIRC, this was one of the really cool features of GTK+ 2, and it isn't possible in GTK+ 1. it certainly is possible, though it can be quite a bit more work. you need to use gtk_widget_shape_combine_mask() together with a GtkEventBox as the underlying widget type. getting full GtkButton semantics from this is hard, but if you want something that responds with generic (ie. button_press, button_release) events, its not that bad. If all you want is the background pixmap to show through, you don't need to do anything special since a GtkButton does not have it's own window but draws on the window of it's parent.

Re: How is GdkPixbuf pixel data stored?
Hi, Christopher Andrew Chenery [EMAIL PROTECTED] writes: My Question is simply why are there two extra bytes per image row, what do they represent and what is a rowstride? - the documentation assumes this knowledge! rowstride is the number of bytes you need to skip to get to the same column in the next row. The reason that this is not equal to width * bpp is simply that memory is most efficiently accessed on word boundaries. For this reason, GdkPixbuf (and other libraries that deal with pixel graphics), assure that pixel rows start on word boundaries. The extra two bytes you see are just for padding and you should never access them. Salut, Sven ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
