Re: Problem grabbing motion-notify events.

Reparenting appears to stop you from receiving all of the events. I have written the test application below to highlight the problem. The application reparents a handle box to a window and then reparents it back to the main application window. I didn't reviewed the full source code but something that hit my eyes is your re-parenting code. You should not take a GtkWidget out of its container without holding a reference to it, as it can be destroyed when you do that. The steps for re-parenting a widget should be: g_object_ref() gtk_container_remove gtk_container_add g_object_unref() But better to try gtk_widget_reparent (). -- Iago Rubio Thank you, It was just a quick hack. I'm beginning to think its a problem with the way events are filtered in the gtk bowels during a grab. I've managed to build gtk, gdk and the gtk-demo last night and it appears to run o.k, so I'll try debugging it later. At least now I will be able to turn the GTK_NOTE ouput on. If it turns out not to be a problem, I should at least be able to ascertain the cause.

g_spawn_async_with_pipes hangs on OSX Tiger
I'm currently porting a GTK+/SDL app to OSX Tiger. In the app I spawn g++ using g_spawn like this: g_spawn_async_with_pipes(path.c_str(), arguments, NULL,G_SPAWN_SEARCH_PATH, NULL, NULL, gpid,in, out, err,error); The code does run and the output file is compiled successfully, but after the g_spawn call my main program will semi hang. I can open new gtk windows but they are not rendered, likewise already open windows are non responsive and I can't close the app. I got the GTK+ libs and headers from darwinports and besides this problem GTK+ runs fine. I have the same code running under Linux and XP so I guess its a OSX port bug. If anyone has any info on this I'd really appreciate it. And if this list is inappropriate I'll post to the darwinports list instead.

problems with threads in a shared object
I have a program that imports plugins via dlopen and dlsym(). In those plugins I use functions like g_mutex_lock to lock a variable, declared in the main program.

How to copy data between widgets?
Hi all, sorry if this is a FAQ, but I've been reading the docs and I couldn't find the answer. Not being too fluent in english, I couldn't find it in the archives, since I don't know what to look for. The problem is the following. I have a text entry, a button and a label. I want the label to display the text in the entry when you press the button. So far I've used g_signal_connect_swapped() connecting the clicked signal on the button with a callback that takes a pointer to the label as data. But I couldn't pass more than that, so I could't pass a string nor the text entry. Another idea I had was passing the window in the callback and operate on the window's children (the widgets), but I didn't find a way to go from a widget to it's chlidren. So i'm kind of stuck here. I'll apreciate any pointer, link and/or cluestick.

But you can pass any kind of pointer, so make a struct, something like this:
struct my_data {
GtkLabel *l;
GtkEntry *e;
};
Then pass a pointer to an instance of your struct. Now you have both widgets
available in your callback.

Ok, thanks, I'll try that.
In fact I had alredy tried and falied, but that could be a problem in
my C-fu, not in my GTK-fu.
IIRC I did
GtkWidget *label;
struct my_data *data;

data-l = label;
and got a Segmentation fault there. But I'll try again I guess

Another way to do it is to assign each widget a string name using
g_object_set_data. Once this is set, then in your callback you can use
the emitting-object's GtkWidget pointer to lookup the parent widget and
then search down the widget hiearchy for the named label widget.
Glade-generated code (which is of course deprecated but demonstrates
this solution) does this:
#define GLADE_HOOKUP_OBJECT(component,widget,name) \
g_object_set_data_full (G_OBJECT (component), name, \
gtk_widget_ref (widget), (GDestroyNotify) gtk_widget_unref)

Which widget should I use?
Hi list! I need to represent some data in my application. The data is actually a trace of functions. The size of the list is not fixed, but it has a limit of 200 elements. When the 200 limit is reached, I clear the older element and then add the new one. I have the list in a file (from procfs) and now I need to show it. I thought about to draw the name of the function inside a rectangle and then an arrow pointing to the next element. Something like this: __ |func1| --- |func2| -- But I don't know what kind of widget I need to use. Maybe this is not the best way to represent this... should I use a treeview to show the list?

Pango Cairo font resolution: shouldn't be specified for both horizontal and vertical?
Hello. I am drawing text on a Cairo context with the help of Pang Cairo. If I use a font with 72 points then an M should be aproximately one inch tall (I guess, maybe I am wrong), for this, I get the resolution of my monitor and I tell that to Pango, so I got my expected result. Luckily my monitor has square pixels, so I have 81 dpi both horizontally and vertically. But now I wonder: ¿what happens on a non square pixel monitor or on a printer? My guess is that the fonts would look distorted because the diferent resolutions aren't taken into account by Pango. I looked in the documentation and header files and I didn't found a function to specify the resolution separately for vertical and horizontal. I am a bit lost now, so I appreciate if someone can iluminate my route to salvation :). Thanks for sharing your knowledge! P.s.: GNOME seems to be using 96 DPI by default although my monitor correctly reports 81 dpi to X _and_ to GTK, so actually my fonts aren't the size they should be in the real physical world, but I will not bug about this until I get more knowledge about fonts, etc..., also, it doesn't have the possibility to specify diferent resolutions for horizontal and vertical... I wonder how fonts would look in a non square pixel monitor though I think those monitors are hard to find today... -- Ivan Baldo - [EMAIL PROTECTED] - http://ibaldo.codigolibre.net/ ICQ 10215364 - Phone/FAX (598) (2) 613 3223.

Re: Which widget should I use?
Fernando Apesteguía wrote: Hi list! I need to represent some data in my application. The data is actually a trace of functions. The size of the list is not fixed, but it has a limit of 200 elements. When the 200 limit is reached, I clear the older element and then add the new one. I have the list in a file (from procfs) and now I need to show it. I thought about to draw the name of the function inside a rectangle and then an arrow pointing to the next element. Something like this: __ |func1| --- |func2| -- But I don't know what kind of widget I need to use. Maybe this is not the best way to represent this... should I use a treeview to show the list? Which are the advantages? Well, unless you have a phenomenally wide screen, 200 boxes pointing to each other as you depict above will never fit. Besides, once you get above 5-10 boxes, comprehension begins to plummet. I'd just put them in a simple list, in whatever order makes sense to your audience (first to last or last to first.) You can do that with a tree view backed by a list store. -- Guy Rouillier ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
RE: help me catch up on GTK gui tools
Calum, Thanks for the links, you've given me a lot of new stuff to look at. I had no idea all of that was available; I was disappointed with the selection at sunfreeware, which is often out of date. I'm surprised to hear that some of the software compiles better with sunstudio. I thought many of the libraries (like gtk) were built with gcc. I would expect better performance from sunstudio (as the native compiler), but more trouble compiling. BTW, I'm interested in GTK for gui development with gtkglext widgets, not for GNOME. I believe solaris opengl support within sunstudio is limited to SPARC workstations, and any testing I would do would be on x86 systems (although, once again, the final destination would be SPARC). Again, thanks for the help. I'm new to a lot of this, so your pointers are definitely helpful.

Pango-1.14.0 released
Pango-1.14.0 is now available for download at: http://download.gnome.org/sources/pango/1.14/ 39144843f377ec6b60dbbf1a25d2a49a pango-1.14.0.tar.bz2 65ecb3d29cebcaf97de14e55831ebb7c pango-1.14.0.tar.gz This is a stable release providing new functionality as compared to Pango-1.12, while maintaining source and binary compatibility. Notable improvements in Pango since version 1.12 include: * Update to Unicode 5.0.0 character database * Improved Indic rendering [LingNing Zhang] * Improved documentation, including list of new symbols added in each stable version of Pango [Priit Laes] * Various bug fixes as usual * The OpenType Layout code in Pango has a new home and name now, and is shared by Qt. HarfBuzz, is still copied internally in Pango, so no separate compilation/installation is necessary. http://www.freedesktop.org/wiki/Software/HarfBuzz About Pango === Pango is a library for layout and rendering of text, with an emphasis on internationalization. Pango can be used anywhere that text layout is needed, though most of the work on Pango so far has been done in the context of the GTK+ widget toolkit. Pango forms the core of text and font handling for GTK+-2.x. Pango is designed to be modular; the core Pango layout engine can be used with different font backends. There are three basic backends, with multiple options for rendering with each. - Client side fonts using the FreeType and fontconfig libraries. Rendering can be with with Cairo or Xft libraries, or directly to an in-memory buffer with no additional libraries. - Native fonts on Microsoft Windows. (Optionally using Uniscribe for complex-text handling). Rendering can be done via Cairo or directly using the native Win32 API. - Native fonts on MacOS X, rendering via Cairo. The integration of Pango with Cairo (http://cairographics.org) provides a complete solution with high quality text handling and graphics rendering. Dynamically loaded modules then handle text layout for particular combinations of script and font backend. Pango ships with a wide selection of modules, including modules for Hebrew, Arabic, Hangul, Thai, and a number of Indic scripts. Virtually all of the world's major scripts are supported. As well as the low level layout rendering routines, Pango includes PangoLayout, a high level driver for laying out entire blocks of text, and routines to assist in editing internationalized text. More information about Pango is available from http://www.pango.org/. Bugs should be reported to http://bugzilla.gnome.org. Pango 1.14.0 depends on version 2.10.0 or newer of the GLib library and version 1.2.2 or newer of the cairo library (if the cairo backend is desired); more information about GLib and cairo can be found at http://www.gtk.org/ and http://cairographics.org/ respectively. 08 August 2006 Behdad Esfahbod ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
