Hi Lance,
The GtkDialog documentation tells only how to access the action area, not its
children. Searching around I see a gtk_container_get_children() which
presumably returns a list of GtkWidget pointers. Is there a way I can look at
a widget pointer and detrmine the widget's type, i.e., figure out whether or
not it's a button? I see references to a gtk_widget_get_type() on the web, but
no good examples of how it's used, and it appears to be not present at all in
my own GTK release's GtkWidget documentation. There also seem to be some
related type discovery functions in the gobject library such as g_type(),
etc., but so far I have not found any useful examples of how I might use them
to figure out if any particular widget pointer is a button or not.
Thanks,
Roger
You would then use g_type_is_a() (possibly), perhaps with G_TYPE_FROM_INSTANCE
and g_type_from_name():
GList *g,*g1;
g1=g=gtk_container_get_children(GTK_CONTAINER(gtk_dialog_get_action_area(dialogbox)));
while(g1);
if (g_type_is_a(G_TYPE_FROM_INSTANCE(g1-data),g_type_from_name(GtkButton))) {
/* do something with button */
g1=g_list_next(g1);
}
g_list_free(g);
You can of course create the dialog without buttons with gtk_dialog_new(), then
add buttons manually with gtk_dialog_add_button(), and save the return value
which is the widget, then change the labels on the buttons when you need to.
That may be easier than the above:
GtkWidget *d;
d=gtk_dialog_new();
GtkButton *b1,*b2;
b1=gtk_dialog_add_button(GTK_DIALOG(d),Wine,1);
b2=gtk_dialog_add_button(GTK_DIALOG(d),Beer,2);
Then do your gtk_dialog_run() later. Then when you need to change the values,
you can just do gtk_button_set_label(b1,Dog); gtk_button_set_label(b2,Cat),
then reshow your dialog and gtk_dialog_run() again.

Hi all, I am trying to code some reusable GtkDialogs (i.e., create them only once, then hide and reuse them later as necessary rather than destroying and recreating every time). I need numerous dialogs which ask a simple question and then have two buttons for the user to choose between, e.g., Favorite drink? Wine/Beer Which way? North/South (Poor examples maybe, but you get the idea.) Seems like a waste to create a bunch of different dialogs that are all using the same basic structure, I would prefer to just create one and then modify its elements as needed. I can see how to change a text label inserted into the dialog's content area to alter my question text, but so far have discovered no way to alter the text labels used in the buttons which I supply at creation time to gtk_dialog_new_with_buttons(). Seems like this ought to be an easy thing to do, but I can see no way to retrieve any pointer to the dialog's button objects nor any way to explicitly set their labels after the dialog has been created.

GtkBuilder issue?
I'm trying to add gtkbuilder support to pike (pike.roxen.com).
In loading a glade3 file, it says Invalid Object 'blah', unless I create an
instance of the object first. I narrowed it down to (in gtkbuilder.c):
static GType
gtk_builder_real_get_type_from_name (GtkBuilder *builder,
const gchar *type_name)
{
GType gtype;
gtype = g_type_from_name (type_name);
if (gtype != G_TYPE_INVALID)
return gtype;
return _gtk_builder_resolve_type_lazily (type_name);
}
Which as you can see, calls _gtk_builder_resolve_type_lazily(). That function
loads the module using GModule, using NULL to load the symbols of itself, find
the *_get_type() function of the object, and calls it to get the type. The
type, of course, is not created until the first time it is used.
For some reason, my code doesn't do that. The binding is a .so file that is
dynamically loaded into the pike interpreter, so I'm hazarding a guess that it
gets the symbols to the current module, which is not libgtk-x11.so (on linux
anyway), so it can't find the *_get_type() function, so it gets G_TYPE_INVALID.
I've been trying different things and so far nothing is working.
Does anybody have any idea how to get around this, to make it resolve properly?
Thanks

Subject: inserting model in a GtkTreeStore
Hi all!
To insert the various nodes in a GtkTreeStore, the code below works for me.
The problem is, this should not work, because I am handling a
GtkTreeIter as if it was some sort of integer, while it is in fact a
structure!
The current child node is the next parent node, so I would expect the
proper
way to do this would be to copy the current node iter to the parent
iter, and
because these are structures, I would have to copy their contents...
What is the standard way of doing this? I am confused!
Thanks!
Carlos
GtkTreeIter insert_row (GtkTreeStore *store, GtkTreeIter *parent, char
*label)
{
GtkTreeIter iter;
gtk_tree_store_append (store, iter, parent);
gtk_tree_store_set (store, iter, 0, label, -1);
return iter;
}
void insert_model (GtkWidget *treeview)
{
GtkTreeStore *store;
GtkTreeIter iter1, iter2, iter3;
store = gtk_tree_store_new (1, G_TYPE_STRING);
iter1 = insert_row (store, NULL, Node 0);
iter2 = insert_row (store, iter1, Node 0:0);

insert_row (store, iter2, Node 0:0:1);
gtk_tree_view_set_model (GTK_TREE_VIEW (treeview), GTK_TREE_MODEL (store));
g_object_unref (store);
}
---
I believe this is copying the struct (which is allowed as of c99 or something,
I believe). Now, if you leave the function and try to use one of the copied
structs, it probably won't work, becuase these iters were allocated on the
stack, and will have been freed. You can do that only if you only will use the
iter in the current function, otherwise you'll want to use it as a pointer
instead.

Subject: GtkTextView: Applying tags at the cursor
Hi,
I'm working on a web site creation software that uses Gtk, Glade and
Python for the UI. I'm using the GtkTextView widget to let the user edit
text with basic formatting but I have a question:
How do I apply a tag at the cursor so that inserted text gets it's
formatting? Right now I surround the cursor with two zero-width spaces
(an invisible Unicode character) and then I apply the tag to the spaces.
This gives new text the right formatting, but it's an ugly solution that
has some bugs...
-
I'm not sure there you can just add a tag at the current cursor position. I'm
creating the GTK2 bindings for the language Pike, and in my tests I created an
array of tags that I need to apply at a certain position, then I added the text
for that position, then applied that tags for that text range. Something like
this:
void insert_text(char *text) {
GtkTextIter *start,*end,*iter;
GtkTextMark *mark;
mark=gtk_text_buffer_get_insert(GTK_TEXT_BUFFER(buffer));
gtk_text_buffer_get_iter_at_mark(GTK_TEXT_BUFFER(buffer),start,mark);
*start=*iter;
gtk_text_buffer_insert(GTK_TEXT_BUFFER(buffer),text,-1);
mark=gtk_text_buffer_get_insert(GTK_TEXT_BUFFER(buffer));
gtk_text_buffer_get_iter_at_mark(GTK_TEXT_BUFFER(buffer),end,mark);
/* foreach tag */
gtk_text_buffer_apply_tag(GTK_TEXT_BUFFER(buffer),tag,start,end);
/* end */
}
I fudged on the foreach array iteration. I have it simpler in pike, but
basically the same thing.

I connect destroy to the window, and it calls my marshaller (I put debug statements in). But, the button-press-event doesn't call my marshaller at all, so it doesn't even get to the rest of the signal handler. I know it works with clicked, destroy, delete, notify, and others.

Thanks, without your help I never catch this feature of GtkTextView,
but there is some minor thing, what about LinkButton, I don't find
such component,
I have to write it?
No, actually, GtkLinkButton is a new widget in 2.10 I think. If you are using
gtk2.10, then just a plain GtkButton, perhaps marked up with an underline so
it looks like a standard hypertext link.
I used GtkButton, but it is appered above the other text, and I can
not find method to make text in it it blue and underlined, here is
code:
--
What I would probably do is create a blank button, create a label with markup,
then add the label to the button, since a button is just a container:
GtkLabel *lab=gtk_label_new();
gtk_label_set_markup(GTK_LABEL(lab),span underline=\single\
foreground=\blue\Link/span);
GtkButton *gb=gtk_button_new();
gtk_container_add(GTK_CONTAINER(gb),lab);
--
#include cstdlib
#include gtk/gtk.h
static void on_link(GtkButton *button, gpointer user_data)

g_debug(on_link\n);

g_signal_connect(G_OBJECT(topLevelWindow), delete_event,
G_CALLBACK(gtk_false), NULL);
g_signal_connect(G_OBJECT(topLevelWindow), destroy,
G_CALLBACK(gtk_main_quit), NULL);
GtkTextView *tv = GTK_TEXT_VIEW(gtk_text_view_new());
gtk_container_add(GTK_CONTAINER(topLevelWindow), GTK_WIDGET(tv));
GtkButton *bt = GTK_BUTTON(gtk_button_new_with_label(link));
gtk_button_set_relief(bt, GTK_RELIEF_NONE);
g_signal_connect(G_OBJECT(bt), clicked, G_CALLBACK(on_link), NULL);
GtkTextBuffer *buffer = gtk_text_view_get_buffer(tv);
GtkTextIter iter;
gtk_text_buffer_get_iter_at_offset(
buffer, iter, 0
);
gtk_text_buffer_insert(buffer, iter, aaa , -1);
GtkTextChildAnchor *anchor =
gtk_text_buffer_create_child_anchor(buffer, iter);
gtk_text_buffer_insert(buffer, iter, \nbbb, -1);
gtk_text_view_set_editable(tv, FALSE);
gtk_text_view_add_child_at_anchor(tv, GTK_WIDGET(bt), anchor);

I would have to test this. I think the gtk example does some anchors inline.

The last problem is, if you trys example, you see that in line aaa Link, the Link and aaa is not on the same line, can GtkTextView care about anchors automaticaly, or I should do it by my self? I don't find API to get height of line in GtkTextView to resize button to it, and interesting what happend if there are no text, only anchors on line, is it climb on the next line? What I'm thinking is that the padding and margin and stuff of the button is adding to the height. Didn't work. What might be better is draw regular lines with markup as needed (blue,underline), and connect to button-press-event. Then, when the button is clicked on one of your links, check whether it was a single click, grab the x and y coordinate of the click, then use gtk_text_view_window_to_buffer_coords() (perhaps?) to find where in the buffer the mouse was clicked. You can create a GtkTextTag that has the appropriate markup (blue, underline) called link or something, then test whether your tag is on for the location, using gtk_text_iter_get_toggled_tags.

Re: GObject exposure
Maybe it is just me, but I don't see a problem with letting users access the
object with gobject methods. If you look at the api, there aren't that many,
and there don't seem to be any that would harm too much. Also, restricting
access too much prevents people from using it in (perhaps beneficial) ways that
you may not have originally imagined.
If you want to, you can override some of the original class methods, such as
{set,get}_property. But perhaps using the methods to your advantage would be
better.
Such as the {set,get}_property methods. You can let the user of the object
change parameters in this way, rather than creating a dozen api calls to change
this parameter, or that one.
Implementing signals could be nice also, let the user attach user-defined
methods/signals/hooks to events that happen with your objects.
Perhaps look at ways to use the gobject methods, rather than seeing them as a
way for users to get around your code...

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.
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.

Re: Fwd: Animation problem
What you can do is use g_object_get_property on the image to get the reference
(or, if it doesn't reference it, you may need to use g_object_ref), then use
g_object_set_property to set the image. This works on GtkImage, for example.

Hi, unfortunately nobody seems to have an idea so far.
Perhaps I can try it more simple:
How can I replace an Image by another one at runtime (without producing a
memory leak)?
In fact this could help to solve the same problem. At least it's worth a try...
Thanks, dasaspock

Betreff: Animation problem
Hi, I have a problem with keeping an animated gif running while the gtk main
loop is blocked.
The gif (called waitImage) is placed on a GtkDialog (waitDialog). The
GdkPixbufAnimation behind waitImage is called waitImageAnimated.
I tried to do it like this:
while(...) {
gtk_widget_queue_draw(GTK_WIDGET (GTK_DIALOG (waitDlg)-vbox));
gdk_window_process_updates (gtk_widget_get_parent_window (GTK_DIALOG
(waitDlg)-vbox), true);
waitImagePixbuf = gdk_pixbuf_animation_iter_get_pixbuf(
gdk_pixbuf_animation_get_iter(waitImageAnimated, NULL));
gtk_image_set_from_pixbuf(GTK_IMAGE (waitImage),waitImagePixbuf);
}
But this doesn't work. The gif doesn't run.
Does anybody know, how to do it correctly?
A solution without memory leaks would be especially nice ;-)
Thank you, dasaspock

Re: Storing GObject in GtkListStore
As far as I can tell you can, as per this example: http://developer.gnome.org/doc/API/2.0/gtk/GtkListStore.html#gtk-list-store-new Notice how they set a column as a GDK_TYPE_PIXBUF, which is derived from G_OBJECT. This implies that you can store anything derived from G_OBJECT in a column designated as such. Of course, you may not be able to display that column unless you have a CellRenderer capable of grabbing some useful information from your object. - Original Message From: Tomasz Jankowski [EMAIL PROTECTED] To: gtk-app-devel-list@gnome.org Sent: Wednesday, August 2, 2006 9:51:08 AM Subject: Storing GObject in GtkListStore Hi! Generally it isn't a problem, I'm only nosy :P I'd like to know if there is some other (more recommended) way to store, for example GObject in GtkListStore/GtkTreeStore. So far I do it, by creating column with type G_TYPE_INT and storing there pointer to object. -- Pozdrawiam!

Re: GObject - problem, as usual
If I understand the problem correctly, you need to call the ancestor method's
manually (regardless of whether it is a finalize methoed or anything else).
There is s section on it in the gobject documentation:

Subject: GObject - problem, as usual
Hi!
I'm writing some application based on GObject and I have problem when I'm
trying to destroy object. I have two object A and B, A derives from GObject
and B derives from A. I declared my own finalize methods for both objects,
but when I'm destroying B object only B finalize function is executed. When
I remowe B finlize function declaration from B_class_init () A finalize
function is executed normaly. Why B finalize method overrides A finalize
method and what should I do to remoe this overriding? Maybe some parts od my
code will be helpful:
GType A_get_type (void) {
/*PRINT_DBG_IN_FUN_NAME*/
static GType type = 0;
if (type == 0) {
static const GTypeInfo info = {
sizeof (AClass),
NULL, /* base_init */
NULL, /* base_finalize */
A_class_init, /* class_init */
NULL, /* class_finalize */
NULL, /* class_data */
sizeof (A),
0, /* n_preallocs */
NULL/* instance_init */
};
type = g_type_register_static (G_TYPE_OBJECT,
AType,
info, 0);
}
return type;
}
GType B_get_type (void) {
/*PRINT_DBG_IN_FUN_NAME*/
static GType type = 0;
if (type == 0) {
static const GTypeInfo info = {
sizeof (BClass),
NULL, /* base_init */
NULL, /* base_finalize */
B_class_init, /* class_init */
NULL, /* class_finalize */
NULL, /* class_data */
sizeof (B),
0, /* n_preallocs */
NULL/* instance_init */
};
type = g_type_register_static (A_TYPE,
BType,
info, 0);
}
return type;
}
static void B_class_init(gpointer g_class,
gpointer class_data)
{
PRINT_DBG_IN_FUN_NAME
GObjectClass *class = G_OBJECT_CLASS (g_class);
GParamSpec *spec;
g_type_class_add_private (class, sizeof (BPrivate));
class-constructor = B_constructor;
class-dispose = B_dispose;
class-finalize = B_finalize;
class-set_property = B_set_property;
class-get_property = B_get_property;
/* other code */
}
static void A_class_init (gpointer g_class,
gpointer class_data)
{
PRINT_DBG_IN_FUN_NAME
GObjectClass *class= G_OBJECT_CLASS (g_class);
GParamSpec *spec;
class-finalize = A_finalize;
class-set_property = A_set_property;
class-get_property = A_get_property;
/* other code */
}
I changed objects names, to make it more legible. PRINT_DBG_IN_FUN_NAME is a
macro, which display function name in console. Here is otput of running
'g_object_unref (g_object_new (A_TYPE, NULL))'. This is program output:
Function: A_class_init
Function: B_class_init
Function: B_constructor
Function: B_dispose
Function: B_finalize
I noticed, that in both *_class_init fnctions I use GObjectClass to declare
finalize, constructor etc. functions on it, is this main reason of my
problem?
