我正在尝试将徽标直接放在标题上的Gtk.Headerbar上。徽标以Microsoft Word创建。 下面是我的部分代码
MainWindow(Gtk.Window)类: “”“包含笔记本的主窗口”“” def init (自己): Gtk.Window。 init (self,title =“”)#由于标题为空白,默认标题栏带有Python图标 self.set_border_width(10) 屏幕= self.get_screen() screen_width = screen.get_width() screen_height = screen.height()
if screen_width > 1366 or screen_height > 768:
self.set_size_request(1300, 800)
else:
self.set_size_request(screen_width, screen_height)
self.set_resizable(True)
self.set_resizable(True)
# self.maximize()
# Creating headerbar & adding it to our window
title = "Pareto"
subtitle = "Shape your world"
header_bar = Gtk.HeaderBar(title=title, subtitle=subtitle)
header_bar.set_show_close_button(True)
samco_logo = Gtk.Image.new_from_file(r"C:\Users\njoshi\Desktop\pareto\icons\pareto_logo1.png")
# this line convert the created icon to an image
header_bar.pack_start(samco_logo)
time_label = TimeLabel() # show time on header bar
header_bar.pack_end(time_label)
self.set_titlebar(header_bar)
# creating a notebook
notebook = Gtk.Notebook()
现在我正在将Gtk.Image小部件用于徽标。我可以使用html直接在代码中设计徽标吗?
答案 0 :(得分:0)
我明白了!我们无法将徽标直接放置在GTK 3中的任何小部件上。只能将图像小部件添加到标题栏顶部。
self.header_bar = Gtk.HeaderBar()
self.header_bar.props.title = "Pareto"
self.header_bar.set_show_close_button(True)
pareto_logo = Gtk.Image.new_from_file(r"loc\image.png")
self.header_bar.pack_start(pareto_logo)

来自https://www.amazon.com/NuWallpaper-NU2235-Florentine-Stick-Wallpaper/dp/B06XT6S6PH的图像仅具有30%的透明度(使用gimp不透明度)
