Re: Accessors vs Properties

For simple setting and getting of values from C, I prefer the accessors because (a) it lets the compiler do some minimal type checking (b) accessors are more efficient at returning a C string than g_object_get. However, you need properties if you want to have a 'parametrized constructor'. ie. pass arguments to a *_new function. Properties are more convenient from higher-level languages. eg., in JavaScript, you can use my_obj.prop to access a property. They also offer extra features: (a) You can bind a property on one object to another property elsewhere (see g_object_bind_property*). (b) Every property comes with its own 'notify' signal that you can use to listen for changes. (c) They can be introspected at run-time, which is very useful if you are writing a tool like the gtk+ inspector, glade or d-feet. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Re: GTK newbie help on G_CALLBACK
button = gtk_button_new_with_label (B1); /* When the button is clicked, we call the callback function * with a pointer to button 1 as its argument */ g_signal_connect (button, clicked, G_CALLBACK (callback), (gpointer) B1); Should be ... G_CALLBACK (callback), button); What I want to do is callback to execute another gtk file What do you mean by execute another gtk file? You don't execute files. You execute functions.

Re: Timed Display of a Dialog
Is it possible to display a dialog for a timed interval (a few seconds) and have it auto-self-destruct? If so, please describe the method(s) of such. You can hide the dialog in a signal handler register using the g_timeout_* API.

Hover decorations in GtkIconView
I have a custom GtkCellRendererPixbuf which I am using to render some thumbnails in a GtkIconView. Now when the mouse passes over a rendered thumbnail I want to slightly highlight/decorate it. As far as I can understand from the documentation my render_vfunc should get GTK_CELL_RENDERER_PRELIT in the flags parameter when the mouse passes over. However, the only value that I am getting are 0 and 1 (ie. GTK_CELL_RENDERER_SELECTED). Any idea how to do this?

Re: Hover decorations in GtkIconView
I don't think items in icon view can be in prelit state. They are either selected or not. You'll probably need to create custom icon view widget to get on-hover effect. Can this be accomplished with a custom GtkIconView or do I need to write it from scratch?

Re: threading choices
If your programming language uses exceptions, remember that leave() call should be inside try..finally cleanup, else this will cause deadlocks if an exception is thrown in-between. If you take C++ as an instance of a programming language with exceptions, then Glibmm offers Glib::Dispatcher for inter-thread communication.

Re: Showing GtkButton in table view
Is there a way to show a standard GtkButton in a table view. I can find examples for toggle buttons but I want a standard button in each row. Try writting your own GtkCellRenderer.
