GLade Python 中带有 CSS 的复选框
Checkbox with CSS in GLade Python
大家 我正在尝试更改复选框被按下时的颜色，因为我正在做一项需要使用它们的工作。我在使用它们时没有 "Drawing Indicator" 属性，所以我需要它们在按下时有不同的颜色，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 型号 B
这是我的代码：

window.connect("destroy", Gtk.main_quit)
window.show_all()
Gtk.main()
由于 Gtk.CheckButton 设置为没有绘制指示器，因此它基本上变成了一个切换按钮，而 CSS class 在 Gtk+ 3.18 上是 .button.
为此 class 定义提供程序并将其添加到屏幕非常简单。
首先，相关css代码为：
.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。
一个有效的例子是：
#!/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 add/remove样式 class 或添加自定义样式 class，等等
编辑：解决问题代码无效。
问题在于 gtk_style () 没有被调用。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 window.connect 行。

Gtk.main()
由于 Gtk.CheckButton 设置为没有绘制指示器，因此它基本上变成了一个切换按钮，而 CSS class 在 Gtk+ 3.18 上是 .button.
为此 class 定义提供程序并将其添加到屏幕非常简单。
首先，相关css代码为：
.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。
一个有效的例子是：
#!/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 add/remove样式 class 或添加自定义样式 class，等等
编辑：解决问题代码无效。
问题在于 gtk_style () 没有被调用。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 window.connect 行。
