使用PyGTK开始我的第一个Python宠物项目。虽然它是一个非常强大的GUI工具包,看起来很棒,但我有一些小小的烦恼。所以我考虑过渡到别的东西,因为它还不是太广泛。看了SO和python documentation,但没有得到很好的概述。
PyGTK有什么好处:
然而,这让我烦恼:
TreeView :因为这是主界面元素,所以它最让人分心。基本上我的应用程序构建了一个要显示的字典列表name = column + row => value。要使用GTK显示它,需要手动转换过程,订购,类型转换。这似乎是很多开销,我希望在这里有一些更面向对象的东西。 PyGtk在gtk +之上有许多抽象,但仍然看起来相当低级。我更喜欢按原样传递我的字典,并以某种方式预定义列。 (GtkBuilder可以预定义TreeView列,但这不能解决数据表示开销。)
当我在TreeView列表上看到mousclick时,我还必须将所有内容转换回我的应用程序数据结构。而且,如果从非主线程运行,PyGTK不会使用gobject.idle本身包装gtk +调用也很令人讨厌。现在有很多GUI代码我认为不应该是必要的,或者可以合理化。
?那么,PyGTK上是否还有其他包装器。或者哪个其他工具包支持更简单的界面来显示Grid / TreeView。我已经阅读了很多关于wxPython是每个人最喜欢的东西,但它在Linux上不太成熟。并且 PyQT 似乎与PyGTK大致相同的抽象级别。没有使用 TkInter ,所以不知道它是否有更简单的接口,但它无论如何看起来没有吸引力。和 PyFLTK 一样。睡衣听起来很迷人,但已经太过分了(桌面应用程序)。
所以,带有dict的GUI工具包 - >网格显示。你会选哪个?
就像展出的那样,这是我当前的TreeView映射功能。一些作品,但我宁愿有一些标准的东西:
#-- fill a treeview
#
# Adds treeviewcolumns/cellrenderers and liststore from a data dictionary.
# Its datamap and the table contents can be supplied in one or two steps.
# When new data gets applied, the columns aren't recreated.
#
# The columns are created according to the datamap, which describes cell
# mapping and layout. Columns can have multiple cellrenderers, but usually
# there is a direct mapping to a data source key from entries.
#
# datamap = [ # title width dict-key type, renderer, attrs
# ["Name", 150, ["titlerow", str, "text", {} ] ],
# [False, 0, ["interndat", int, None, {} ] ],
# ["Desc", 200, ["descriptn", str, "text", {} ], ["icon",str,"pixbuf",{}] ],
#
# An according entries list then would contain a dictionary for each row:
# entries = [ {"titlerow":"first", "interndat":123}, {"titlerow":"..."}, ]
# Keys not mentioned in the datamap get ignored, and defaults are applied
# for missing cols. All values must already be in the correct type however.
#
@staticmethod
def columns(widget, datamap=[], entries=[], pix_entry=False):
# create treeviewcolumns?
if (not widget.get_column(0)):
# loop through titles
datapos = 0
for n_col,desc in enumerate(datamap):
# check for title
if (type(desc[0]) != str):
datapos += 1 # if there is none, this is just an undisplayed data column
continue
# new tvcolumn
col = gtk.TreeViewColumn(desc[0]) # title
col.set_resizable(True)
# width
if (desc[1] > 0):
col.set_sizing(gtk.TREE_VIEW_COLUMN_FIXED)

尝试Kiwi,也许吧?尤其是ObjectList。
更新:我认为新西兰的发展已经转移到PyGTKHelpers。

我之前没有遇到过新西兰人。谢谢,Johannes Sasongko。
以下是我保留书签的更多关注点。其中一些是围绕其他工具包(GTK,wxWidgets)的包装器,而其他工具包是独立的:
(我已经包含了一些为了遇到这篇文章而被提及的人。我会把它作为评论发布,但是有点太长了。)

I would suggest taking a look at wxPython。虽然我不得不承认我自己没有对Treeviews做过很多事情,但我发现它很容易上手并且非常强大。
wxWidgets将等效控件称为wxTreeCtrl
[编辑] wxDataViewTreeCtrl实际上可能更适用于您的情况。
