sensitive state in ComboBox menus
Hi! How can I set a row in a combobox menu as insensitive/sensitive and know the current sensitive state, for: 1) a combo box created with gtk_combo_box_new_text 2) a more general combo box created with a tree model In option menus, I used: gtk_widget_set_sensitive (item, FALSE); but this does not work here, as rows are not widgets anymore... Many thanks for your help!

Re: setting the font of a dialog widget

Maybe I'm misunderstanding something, but it seems that the solution you recommend is solely a solution for Gtk::Labels -- not for general widgets. I can change the font size for labels -- but not for other widgets (e.g. CheckButton, RadioButton.). That's my issue. All of the button classes are containers with a single 'display' widget packed inside. The display widget is usually a label, but it can be anything (a pixmap, for example, or an hbox with a pixmap and a couple of labels). So to use pangomarkup to set the font size, cast the button to GtkBin and get the child, then use gtk_label_set_markup() to set the label's font size. label = gtk_bin_get_child (GTK_BIN (button)) gtk_label_set_markup (GTK_LABEL (label), ...) You can also set the font size from resource files. If you want to set the size for all labels, that might be a better solution. Pangomarkup is good if you want to mix font sizes or attributes within a single label.

Going fullscreen and back
Hi there, The small working code below shows how my app goes fullscreen and back. 1) Is there a better way of doing this? 2) This code works fine in Enlightenment, KDE, BlackBox, IceWM, etc. In Gnome and XFCE it works, but the desktop bars are still visible (I suppose it should be possible to change this?). However, in GNOME and only in GNOME, I have to subtract 1 pixel, on width or height, for this to work. In other words, if I replace this: gdk_window_move_resize (window-window, 0, 0, gdk_screen_width (), gdk_screen_height () - 1); by this: gdk_window_move_resize (window-window, 0, 0, gdk_screen_width (), gdk_screen_height ()); poor Gnome WM gets confused, indeed goes fullscreen, but does not come back... :-( What is the best way to handle this? going fullscreen is a very useful feature in many scientific/engineering apps.

Why not use gtk_window_fullscreen? I've only tried it on a Gnome desktop, it works well.

Jim, Kevin, Thanks! It works fantastically well, I just tried it on GNOME, XFCE, KDE, Enlightenment, Blackbox, IceWM, always with correct results. Moreover, is is much faster than my version and all the annoying flashing effects are gone! Thanks!

Re: inserting model in a GtkTreeStore
- Original Message From: Carlos Pereira [EMAIL PROTECTED] Cc: gtk-app-devel-list@gnome.org Sent: Sunday, April 27, 2008 12:10:27 PM 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 0:0:0); 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. Be a better friend, newshound, and know-it-all with Yahoo! Mobile.

For changing the position of a child in the vbox you can use the api gtk_box_reorder_child ().Refer the following link http://library.gnome.org/devel/gtk/stable/GtkBox.html#gtk-box-reorder-child.

Re:Re: setting the font of a dialog widget
hi , you can change the font size of a general widget from rc file. Refer the following code. /// style dialogstyle = default { font_name = Sans 20 } widget_class *Dialog* style dialogstyle Include the above code to rc file . It works.
