Re: gtk_tree_view/store, best way to select all nodes of a branch
My current simple solution is as follows: I use the gtk_tree_model_foreach() function and pass some user data with the current major number of the tree-path. Inside the foreach-function I use gtk_tree_path_to_string, where I check if the first number is identical to the user data. This works, but I have to use a lot of string functions. Is there a smarter way to do that with less overhead? regards Arne ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Use gtk_tree_model_iter_n_children() and gtk_tree_model_iter_nth_child() recursively to always move to the last child in the branch. If your tree is only two-level (as it seems to be) you do not even need to recurse.

populate gtk tree view from outside
Dear friends,
I have defined a treeview model as follows:
enum
{
COL_FIRST_NAME = 0,
COL_LAST_NAME,
COL_YEAR_BORN,
NUM_COLS
} ;
static GtkTreeModel *
create_and_fill_model (void)
{
GtkTreeStore *treestore;
GtkTreeItertoplevel, child;
treestore = gtk_tree_store_new(NUM_COLS,
G_TYPE_STRING,
G_TYPE_STRING,
G_TYPE_UINT);
int i;
FILE *fauth;
char alst[10][500], buffer[500];
fauth=fopen(fauth.dat,r);
if(!fauth){
printf(fauth failed\n);
}
while(fgets(buffer,500,fauth)){
strcpy(alst[i],buffer);
i++;
}
fclose(fauth);
for (i = 0; i 10; i++){
gtk_tree_store_append(treestore, toplevel, NULL);
gtk_tree_store_set(treestore, toplevel,
COL_FIRST_NAME, alst[i],
COL_LAST_NAME, Average,
COL_YEAR_BORN, (guint) 1962,
-1);
}
return GTK_TREE_MODEL(treestore);
}
static GtkWidget *
create_view_and_model (void)
{
GtkTreeViewColumn *col;
GtkCellRenderer *renderer;
GtkWidget *view;
GtkTreeModel*model;
view = gtk_tree_view_new();
col = gtk_tree_view_column_new();
gtk_tree_view_column_set_title(col, First Name);
gtk_tree_view_append_column(GTK_TREE_VIEW(view), col);
renderer = gtk_cell_renderer_text_new();
gtk_tree_view_column_pack_start(col, renderer, TRUE);
gtk_tree_view_column_add_attribute(col, renderer, text,
COL_FIRST_NAME);
gtk_tree_view_column_pack_start(col, renderer, TRUE);
model = create_and_fill_model();
gtk_tree_view_set_model(GTK_TREE_VIEW(view), model);
g_object_unref(model);
gtk_tree_selection_set_mode(gtk_tree_view_get_selection(GTK_TREE_VIEW(view)),
GTK_SELECTION_NONE);
return view;
}
//For brevity, I have cut out the 2nd and 3rd column
In a different function, I have
strAuth = gtk_entry_get_text(GTK_ENTRY(e-entryAuth));
strEditor = gtk_entry_get_text(GTK_ENTRY(e-entryEditor));
Is it possible to add these strAuth, strEditor in those treeview's 1st
and 2nd column?

The problem basically is to pass on the function argument from one to other. you need to create a header file (main.h) that has the enum, and extern GtkListStore *treestore; in main.c define GtkListStore *treestore; somewhere in the top of fthe file, *not* inside a function. then include this both in main.c and in otherfile.c like #include main.h Olivier ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: populate gtk tree view from outside
Oliver, Thanks a lot. Its working properly. Only change that I have made is using gtk_tree_store_append in place of gtk_tree_model_get_iter_first. Thanks a lot again.

Gtk.DrawingArea: Port to python3/gtk3
Hi,
How should I convert this gtk3?
self.area = Gtk.DrawingArea()
#Paints the piano roll (Where the notes are)
def paint_widget(self):
if self.area.window == None:
return
colormap = self.area.get_colormap()
if self.gc_background == None:
color_background = colormap.alloc_color('#FF',
True, True)
self.gc_background = self.area.window.new_gc()
self.gc_background.set_foreground(color_background)
