每个人 我正在尝试在按下复选框时更改它们的颜色，因为我正在做一项需要使用它们的工作。我使用的它们没有“绘图指示器”属性，所以我需要它们在按下时具有不同的颜色，因为它看起来不太好而且不太吸引人。有什么办法吗？我的glade版本是3.18.3。我使用的是 Pi3 模型 B
这是我的代码:

#Checkbuttons

print("port " + name + " toggled, state is " +state)

window.connect("destroy", Gtk.main_quit)
window.show_all()
Gtk.main()
最佳答案
由于 Gtk.CheckButton 没有绘制指示器，所以它基本上变成了一个切换按钮和 CSS 类，在 Gtk+ 3.18 上是 .button。
为此类定义提供程序并将其添加到屏幕非常简单。
首先，相关的css代码是:
.button:checked {
color: white;
background: red;
}
对于此示例，选中该按钮时，该按钮将具有红色背景和白色文本。
一个可行的例子是:
#!/usr/bin/python3
from gi.repository import Gtk, Gdk
import sys
class MyWindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title="Hello World")
self.set_name('MyWindow')
self.set_default_size(600, 300)
self.box = Gtk.HBox()
self.box.set_halign(Gtk.Align.CENTER)
self.box.set_valign(Gtk.Align.CENTER)
self.add(self.box)
self.button1 = Gtk.CheckButton(label="1")
self.button1.set_mode (False);
self.button1.connect("clicked", self.on_button1_clicked)
self.box.pack_start(self.button1, True, True, 0)
self.button2 = Gtk.CheckButton(label="2")
self.button2.set_mode (False);
self.button2.connect("clicked", self.on_button2_clicked)
self.box.pack_start(self.button2, True, True, 0)
def on_button1_clicked(self, widget):
print("Button 1")
def on_button2_clicked(self, widget):
print("Button 2")
def main(argv):
def gtk_style():
css = b"""
.button:checked {
color: white;
background: red;
}
"""
style_provider = Gtk.CssProvider()
style_provider.load_from_data(css)
Gtk.StyleContext.add_provider_for_screen(
Gdk.Screen.get_default(),
style_provider,
Gtk.STYLE_PROVIDER_PRIORITY_APPLICATION
)
gtk_style()
win = MyWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()
if __name__ == "__main__":
main(sys.argv)
结果是这样的:
这将对所有复选按钮应用相同的行为，因此如果想法是仅在那些编号的按钮上使用此解决方案但想在应用程序上使用另一个复选按钮(作为切换按钮)，那么您需要添加/删除样式类或添加自定义样式类等。
编辑:解决问题代码不起作用。
问题在于没有调用 gtk_style ()。该调用在其自己的定义中:
def gtk_style():
...code...
gtk_style() # <----- Here is the problem.
Python 缩进是相关的。现在的样子，它变成了递归的，它没有被调用。解决方案是删除该行并将其移动到下面的代码中，例如，在 window.connect 行之后。
