Re: how to replace a child of a GtkBox ?
Hi Gregory! - How do I remove the old object from the GtkBox ? - How do I free up the old object (image/pixbuf) ? Do I simply unref it ? You don't have to do any of these. As a general rule of thumb in the gobject world, each object keeps it's own reference of the objects it needs. So when you set a new child on a GtkBox object, the GtkBox must unref the old child widget. -- Regards, Zeeshan Ali Khattak FSF member#5124 ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Re: GdkPixbuf object from stock icons
Hi! Not so obviously. The primary difficulty is that your problem is ill-posed. The stock icon look is affected by theme, state and whatnot. It can even differ for different widgets. I know that and that is why i only using the stock icons where the change of actual icon image doesn't make any difference to the user of my app. i-e use GTK_STOCK_DIRECTORY to represent a directory. So depending on your preferred amount of manual work you have the choice of gtk_widget_render_icon() gtk_icon_set_render_icon() gtk_style_render_icon() The most raw method is gtk_icon_theme_lookup_icon() + gtk_icon_info_load_icon() I thought icon theme is different from stock icons? -- Regards, Zeeshan Ali FSF member#5124 ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Re: How does one pipe output from process to text buffer?
Hello Tomas! Just a thought: Wouldn't it be a better idea to use a library instead of a command when one is available: libssh (http://www.0xbadc0de.be/libssh:libssh). Thanks. Didn't know about that. Just from a cursory glance at the doc: * what I like clean, abstract interface Yes! me too. * what I don't namespace pollution (besides the prefix ssh_ they use options_ channel_ and what not). I agree but keep in mind that: 1. The developer is a very friendly guy and takes user feedback very seriously so you can suggest this to him and he'll do whatever seems appropriate to change things for good. 2. The API is a bit different in the upcoming release: 0.2. In Tony's case, he might have to extract the fd from the SSH_SESSION object (is there an interface for that?) to be able to stuff it into a GIOChannel (not very difficult. I've done it with a database socket). On the plus side, Tony would just have *one* socket to watch (read and write side), and errors would (assumedly) come through call results or whatever. I have already thought of implementing a GIOChannel based on the libssh's CHANNEL object and i already discussed the possbility of having that in the libssh itself with the developer but he wasn't particularly interested in glib's mainloop integration so i have put it in the TODO list of my project. It would be doing that now if there were some documentation on how to implement your own GIOChannel but the glib docs seems to even abstract the GIOChannel structure even so i'll have to get into the sources. -- Regards, Zeeshan Ali Design Engineer, SW Open Source Software Operations Nokia Multimedia ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Re: Passing data from a data collection window back to a main
Hi!
The best and simplest way to get rid of global varriables would be
to define a structure that would contain all the data you need and
then you can keep passing it's pointer around in the callbacks using
the 'user_data' argument. If you want to use g_object_set/get_data()
instead, thats also possible and very easy (you don't even have to
define a new structure, since you can assign different string keys for
different kinds of data). IMHO, the g_object_set/get_data() API
reference (1) is good enough and there doesn't need to be an example
code for all possible scenerios in the tutorials/docs.
1.

Hi,

g_object_set_data, but have not progressed to being able to use it
confidently.
Does anyone know of a simple example using g_object_set_data. The sort of
thing I am thinking about is a main window with a label and button, that
pops up a child window with an entry and a button. Clicking the child
windows button returns the string in the entry back to the main windows
label.
This sort of example would be very useful in the tutorial.

Re: Window Visibility Signal
Hello, Expose is no problem, but what about when it is hid? basically I want to know when the window is hid, so I don't draw to it. If you only want to check if a widget is visible or not at a particular time, you'll need to check for the 'visible' property of the widget. Moreover, 'expose' signal is called for both the cases (show and hide). If you choose to go the 'expose' way then connect your handler using g_signal_connect_after(). -- Regards, Zeeshan Ali ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Hello, Nice tip, but unfortunately the expose event does not signal when the object is covered up. Only when revealed. I even hooked event and event-after and nothing was emitted when I covered up the window. Only events were triggered when I moved the mouse into the window and out of it and clicks. Try visibility-notify-event and try all the other (likely) signals of GtkWidget documented in the gtk+ reference manual please if this doens't work either.

Re: Glade C code a bad thing? (was: root windows)
Hello everyone, I strongly agree with the opinion that source-code generation should be removed from glade itself. OTOH I very strongly advice the glade developers to write a nice command-line utility to convert a glade file to it's equivalent source code in C/C++, before they drop this support. Since the glade file is XML, I think the tranformation to source-code could also be better done using XSL, right? If someone wan't to write it as a script without using any XML libs. i'll advice him/her to use scheme/lisp instead of perl/python as lisp is AFAIK the best language to deal with XML. Another option would be to write such a utility in C, which shouldn't be that hard if we borrow the same code from Glade that is to be removed. :) BTW, i think this seperation of glade into two utilities would result in much greater freedom than now (quite contrary to the fear of some people on this list) since it open's up a new possiblity: you'll then be able to write your GUI in XML and getting it transformed into the source-code without using any GUI utility. :) -- Regards, Zeeshan Ali ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
