PyGTK 예제 소스를 순수 API를 호출하는 방법과 GtkBuilder를 사용한 방법으로 각각 구현해본다.
Hello, World
아래와 같은 모습을 가지도록 프로그램을 수정한다.
API 호출
코드
hello.py
#!/usr/bin/python
# -*- coding: utf-8 -*-
import gtk
class HelloWorld :
def hello(self, widget, data=None) :
print 'Hello, World'
def delete_event(self, widget, event, data=None):
print 'delete event occurred'
return False
def destroy(self, widget, data=None) :
gtk.main_quit()
def __init__(self) :
self._win = gtk.Window(gtk.WINDOW_TOPLEVEL)
self._win.connect('delete_event', self.delete_event)
self._win.connect('destroy', self.destroy)
self._win.set_border_width(10)
self._btnhello = gtk.Button('Hello World')
self._btnhello.connect('clicked', self.hello, None)
self._btnhello.connect_object('clicked', gtk.Widget.destroy, self._win)
self._win.add(self._btnhello)
def main(self) :
self._win.show_all()
gtk.main()
def main() :
w = HelloWorld()
w.main()
if __name__ == '__main__' :
main()GtkBuilder
GtkBuilder를 사용하면 ui 구성 코드를 xml로 분리할 수 있다.
코드
