GtkDialog
create popup windows.
Dialog boxes are a convenient way to prompt the user for a small amount of
input, eg. to display
a message, ask a question, or anything else that does not require extensive
effort on the user's part.
Gtk+ treats a dialog as a window split horizontally. The top section is a
#GtkVBox, and is where widgets such as a #GtkLabel or a #GtkEntry should be
packed. The second area is known as the action_area. This is generally used
for packing buttons into the dialog which may perform functions such as cancel, ok, or apply. The two
areas are separated by a #GtkHSeparator.
#GtkDialog boxes are created with a call to gtk_dialog_new().
If 'dialog' is a newly created dialog, the two primary areas of the window
can be accessed as GTK_DIALOG(dialog)->vbox and GTK_DIALOG(dialog)->action_area,
as can be seen from the example, below.
A 'modal' dialog (that is, one which freezes the rest of the application
from user input), can be created by calling gtk_window_set_modal() on the dialog. Use the
GTK_WINDOW() macro to cast the widget returned from gtk_dialog_new() into a
#GtkWindow.
Using a #GtkDialog to keep the user informed.
/* Function to open a dialog box displaying the message provided. */
void quick_message(#gchar *message) {
#GtkWidget *dialog, *label, *okay_button;
/* Create the widgets */
dialog = gtk_dialog_new();
label = gtk_label_new (message);
okay_button = gtk_button_new_with_label("Okay");
/* Ensure that the dialog box is destroyed when the user clicks ok. */
gtk_signal_connect_object (GTK_OBJECT (okay_button), "clicked",
GTK_SIGNAL_FUNC (gtk_widget_destroy), dialog);
gtk_container_add (GTK_CONTAINER (GTK_DIALOG(dialog)->action_area),
okay_button);
/* Add the label, and show everything we've added to the dialog. */
gtk_container_add (GTK_CONTAINER (GTK_DIALOG(dialog)->vbox),
label);
gtk_widget_show_all (dialog);
}
#GtkVBox
Pack widgets vertically.
#GtkWindow
Alter the properties of your dialog box.
#GtkButton
Add them to the action_area to get a
response from the user.
window is a #GtkWindow, but should not be
modified directly, (use the functions provided, such as
gtk_window_set_title(). See the #GtkWindow section for more).
vbox is a #GtkVBox - the main part of the dialog box.
action_area is a #GtkHBox packed below the dividing #GtkHSeparator in the dialog. It is treated exactly the same as any other #GtkHBox.
Deprecated.
Creates a new dialog box. Widgets should not be packed into this #GtkWindow
directly, but into the vbox and action_area, as described above.
@Returns: a #GtkWidget - the newly created dialog box.
