Thank you for all your help. But this is exactly the problem. Gtk3::SourceView::CompletionProvider has no "new"-method. Enclosed you will find the solution of this problem in python. I don't master this language, but perhaps someone is also experienced in python and can help to translate this in the perl syntax:
class TestProvider(GObject.Object, GtkSource.CompletionProvider):
__gtype_name__ = 'TestProvider'
def __init__(self):
GObject.Object.__init__(self)
self.priority = 1
theme = Gtk.IconTheme.get_default()
icon = theme.load_icon(Gtk.STOCK_DIALOG_INFO, 16, 0)
self.proposals = []
self.proposals.append(GtkSource.CompletionItem.new("Proposal 1", "Proposal 1", icon, "blah 1"))
self.proposals.append(GtkSource.CompletionItem.new("Proposal 2", "Proposal 2", icon, "blah 2"))
self.proposals.append(GtkSource.CompletionItem.new("Proposal 3", "Proposal 3", icon, "blah 3"))
def do_get_name(self):
return "Test Provider"
def do_get_priority(self):
return self.priority
def do_match(self, context):
return True
def do_populate(self, context):
proposals = [
GtkSource.CompletionItem(label='Hello World!', text='Hello World!', icon=None, info=None) # always proposed
context.add_proposals(self, self.proposals, True)
def set_priority(self, priority):
self.priority = priority
GObject.type_register(TestProvider)
