Python/Glade/PyGTK - 检查复选框是否选中
我在学习PyGTK库和相关教程的时候，没能找到我想要的确切答案，或者可能是我做错了什么……
总之，我正在学习PyGTK和Glade，现在正在编写一个简单的下载器应用程序。这个应用的界面上有三个复选框，还有一个提交按钮。
我想做的是在点击提交按钮后获取复选框的状态，这样我就可以根据复选框是选中还是未选中来继续我的下载脚本。
这是我目前的进展。（还处于非常早期的阶段，正在从错误中学习）
Python脚本：
import sys
try:
import pygtk
pygtk.require("2.0")
except:
pass
try:
import gtk
import gtk.glade
except:
sys.exit(1)
class GladeTest:
def __init__(self):
#Set the Glade file
filename = "gui.glade"
builder = gtk.Builder()
builder.add_from_file(filename)
builder.connect_signals(self)
#Create our dictionay and connect it
dic = { "btnSubmit_clicked" : self.btnSubmit_clicked,
"chkboxDropbox_toggled" : self.chkboxDropbox_toggled,
"MainWindow_destroy" : gtk.main_quit }
def btnSubmit_clicked(self, widget):
self.button = gtk.ToggleButton("chkboxDropbox_toggled")
status = self.button.get_active()
print status
def chkboxDropbox_toggled(self, widget):
print ""
if __name__ == "__main__":
hwg = GladeTest()
gtk.main()

要么是我找不到正确的方法来获取状态，要么是我找到了但用错了……任何帮助都非常感谢，提前谢谢大家！

在这个回调函数里：
def btnSubmit_clicked(self, widget):
self.button = gtk.ToggleButton("chkboxDropbox_toggled")
status = self.button.get_active()
print status
你实际上是在创建一个全新的切换按钮，但这个按钮是看不见的，因为你没有把它放到其他的控件里去。所以，当你去询问它的状态时，它并没有像你预期的那样响应。

你只需要调用gtk复选框的“get_active”方法，从glade文件中获取复选框的对象，然后在提交按钮的点击事件中调用“get_active”方法。
这里有一段代码示例，能让你更清楚：
class GladeTest:
def __init__(self):
#Set the Glade file
filename = "gui.glade"
self.builder = gtk.Builder()
self.builder.add_from_file(filename)
self.builder.connect_signals(self)
#Create our dictionay and connect it
dic = { "btnSubmit_clicked" : self.btnSubmit_clicked,
"chkboxDropbox_toggled" : self.chkboxDropbox_toggled,
"MainWindow_destroy" : gtk.main_quit }
def btnSubmit_clicked(self, widget):
chkbt_chrome = self.builder.get_object("chkboxChrome")
print "ACTIVE--",chkbt_chrome.get_active()
# do same for rest of the check buttons
self.button = gtk.ToggleButton("chkboxDropbox_toggled") # if used for check box status then there is no need for this button.
status = self.button.get_active()
print status
def chkboxDropbox_toggled(self, widget):
print ""
if __name__ == "__main__":
hwg = GladeTest()
gtk.main()
希望这能对你有所帮助。
