在下图中,您可以看到3父子窗口。实际上我做了一个代码,根据父母显示所有孩子。这显示正确,但我想要用户名和&密码列仅可用于数据库父级(如第3个窗口)。其他不应该是可编辑的。
在我的情况下,父母的所有孩子都是可编辑的。
这是我的代码
#!/usr/bin/env python
import pygtk
pygtk.require('2.0')
import gtk, gobject
import os
import cairo, gio, pango, pangocairo, atk
class BasicTreeViewExample:
# close the window and quit
def delete_event(self, widget, event, data=None):
gtk.main_quit()
return False
def col1_toggled_cb( self, cell, path, model ):
model[path][1] = not model[path][1]
def on_cell_edited(self, cell, path_string, new_text, model):
print "hi"
#cell.set_property('editable', False)
iter = model.get_iter_from_string(new_text)
path = model.get_path(iter)[0]
column = cell.get_data("username")
def __init__(self):
# Create a new window
self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
self.window.set_title("Basic TreeView Example")
self.window.set_size_request(400, 400)
self.window.connect("delete_event", self.delete_event)
self.treestore = gtk.TreeStore(gobject.TYPE_STRING, gobject.TYPE_BOOLEAN,gobject.TYPE_BOOLEAN, gobject.TYPE_STRING, gobject.TYPE_STRING)

任何人都可以帮我解决这个问题。
...谢谢

这里的答案类似于上一个问题的答案:您需要使用指定您关注的属性的附加列扩展树存储 - 在这种情况下,特定行的用户名/密码单元格的可编辑性,并将该存储列与显示和编辑用户名和密码的树视图列连接。
提供的代码只是将editable
属性设置为true,这意味着该属性在任何地方都可以编辑。
有tutorials详细解释了GTK树视图。以下是问题代码的一个版本,根据我的理解进行了修改以符合您的要求。
