if write code like this:  
#########  
class LoginDialog \< Gtk::Dialog  
def initliaze  
super  
show\_all  
end  
end  
l=LoginDialog.new :title=\>“login”,  
:parent=\>nil,  
:flags=\>Gtk::Dialog:🎏:MODAL,  
:buttons=\>[[Gtk::Stock::OK,Gtk::ResponseType::OK],  
[Gtk::Stock::CANCEL,Gtk::ResponseType::CANCEL]]  
l.run  
l.destroy  
Gtk.main  
##########  
the code will work well.  
when i init paramet in the class, write code like this:  
##########  
class LoginDialog \< Gtk::Dialog  
def initliaze  
super :title=\>“login”,  
:parent=\>nil,  
:flags=\>Gtk::Dialog:🎏:MODAL,  
:buttons=\>[[Gtk::Stock::OK,Gtk::ResponseType::OK],  
[Gtk::Stock::CANCEL,Gtk::ResponseType::CANCEL]]  
show\_all  
end  
end  
l=LoginDialog.new  
l.run  
l.destroy  
Gtk.main  
##########  
the class can’t be init,why?

None works for me.

From the docs, GtkDialog does not take a hash as options. Unless you use  
type\_register, which does not seem the case.

Here is a working example :

require ‘gtk2’

class LoginDialog \< Gtk::Dialog  
def initialize  
super “Test Login Dialog”,  
nil,  
Gtk::Dialog:🎏:MODAL,  
[Gtk::Stock::OK,Gtk::ResponseType::OK],  
[Gtk::Stock::CANCEL,Gtk::ResponseType::CANCEL]  
show\_all  
end  
end

l = LoginDialog.new

l.run  
l.destroy  
Gtk.main

NB : There is a typo in your ‘initialize’ also.

regards

Simon

Typo in “def initialize” is hard to spot - I also sometimes write “def  
intialize”.
