Question

所以我的traitsUI代码有问题。我想要的是一个使用CheckListEditor（）显示的List，它位于一个受限制的空间中，因此它可以滚动。我需要将这个List放在一个组中，因为这只是整个GUI的一小部分。然而，如果我设置Group属性＆＃34;可滚动＆＃34; to＆＃34; True＆＃34;什么都不做。有任何想法吗？这是最小的工作示例：

from traits.api import HasTraits, List
from traitsui.api import View, ListEditor, Group, Item, CheckListEditor, Group


class Foo(HasTraits):
    my_list = List()
    full_list = List()

    def _full_list_default(self):
        return [str(n) for n in range(10)]

    traits_view = View(Group(Item('my_list',
                                  style='custom',
                                  editor=CheckListEditor(name = 'full_list')),
                             scrollable = True,
                             orientation = 'vertical'),
                       height=100)

if __name__ == '__main__':
    f = Foo()
    f.configure_traits()

应该可以滚动View：

from traits.api import HasTraits, List
from traitsui.api import (
    View, ListEditor, Group, Item, CheckListEditor, Group
)

class Foo(HasTraits):
    my_list = List()
    full_list = List()

    def _full_list_default(self):
        return [str(n) for n in range(10)]

    traits_view = View(Group(Item('my_list',
                                style='custom',
                                editor=CheckListEditor(name='full_list')),
                            orientation='vertical'),
                    scrollable=True,
                    height=100)

if __name__ == '__main__':
    f = Foo()
    f.configure_traits()

我明白了：

如果您要嵌入多个可滚动视图，可以使用Instance和InstanceEditors执行此操作：

    from traits.api import HasTraits, List, Instance
from traitsui.api import (
    View, ListEditor, Group,InstanceEditor, Item, CheckListEditor, Group,
    VGroup
)

class Foo(HasTraits):
    my_list = List()
    full_list = List()

    def _full_list_default(self):
        return [str(n) for n in range(10)]

    traits_view = View(Group(Item('my_list',
                                style='custom',
                                editor=CheckListEditor(name='full_list')),
                            orientation='vertical'),
                    scrollable=True,
                    height=100)

class FooContainingView(HasTraits):
    foo_1 = Instance(Foo)
    foo_2 = Instance(Foo)

    traits_view = View(
        VGroup(
            Item('foo_1',
                editor=InstanceEditor(),
                style='custom',
                show_label=False,
            ),
            Item('foo_2',
                editor=InstanceEditor(),
                style='custom',
                show_label=False,
            ),
        ),
        resizable=True,
    )


if __name__ == '__main__':
    f = Foo()
    fcv = FooContainingView(foo_1=Foo(), foo_2=Foo())
    fcv.configure_traits()

......结果如下：

使用TraitsUI的带有List的可滚动组
