우분투 애플리케이션을 만들려고 합니다. 버튼 클릭 시 이미지가 변경되도록 Glade의 배경 이미지의 특정 위치에 투명 버튼을 배치해야 합니다.
나는 지금까지 이것을 달성하지 못했습니다. 내 버튼이 이미지 위에 놓이지 않습니다. 또한 버튼을 완전히 투명하게 만들 수도 없습니다(즉, 누르면 표시됩니다).
답변1
GtkFixed고정된 버튼 위치의 경우 또는GtkLayout(스크롤 사용)을 사용하는 것이 좋습니다.- 버튼 투명성의 경우 제게는 제대로 작동합니다. 시도하지 않을 경우:
Border Relief:None플랫 버튼용Focus on Click초점 강조 표시를 피하려면 선택을 취소하세요.

처음으로 데스크탑 배경을 말씀하시는 줄 알았습니다. 그래서 다른 분들에게도 도움이 될 수 있도록 남겨둡니다.
Quickly(Ubuntu 13.04)에서 어떤 버전의 PyGTK를 사용하는지 잘 모르겠습니다. 테스트하려면 불투명도 0.1을 사용하는 것이 좋습니다. Glade는 속성을 설정하는 옵션을 제공하지 않습니다 keep_below.

오류가 발생했기 때문에 이에 대해 댓글을 달았습니다(Glade에 다른 방법이 있는지는 확실하지 않습니다).
<!-- <property name="keep_below">True</property> -->
<!-- <property name="position">gtk.WIN_POS_CENTER_ALWAYS</property> -->
따라서 동적으로 적용되도록 .py 파일에 추가합니다.
window.set_keep_below(True)
window.set_position(Gtk.WindowPosition.CENTER_ALWAYS)
builder_example.py
from gi.repository import Gtk
class Handler:
def onDeleteWindow(self, *args):
Gtk.main_quit(*args)
def onButtonPressed(self, button):
print("Hello World!")
builder = Gtk.Builder()
builder.add_from_file("builder_example.glade")
builder.connect_signals(Handler())
window = builder.get_object("window1")
window.set_keep_below(True)
window.set_position(Gtk.WindowPosition.CENTER_ALWAYS)
window.show_all()
Gtk.main()

추가하다:
self.window.set_keep_below(True)
