我正在尝试减少在Gtk + Python中编辑treeview单元格时出现的编辑框的大小。
这是我的代码:
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
class CellRendererTextWindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title="CellRendererText Example")
self.set_default_size(200, 200)
self.liststore = Gtk.ListStore(str, str)
self.liststore.append(["Fedora", "http://fedoraproject.org/"])
self.liststore.append(["Slackware", "http://www.slackware.com/"])
self.liststore.append(["Sidux", "http://sidux.com/"])
treeview = Gtk.TreeView(model=self.liststore)
select_render = Gtk.CellRendererToggle()
select_render.set_property('activatable', True)
select_render.set_property("radio", True)
select_render.connect('toggled', self.on_toggle)
select_column = Gtk.TreeViewColumn(" %s" %('Select'), select_render,
active=0)
select_column.set_clickable(True)
treeview.append_column(select_column)
renderer_text = Gtk.CellRendererText()
renderer_text.set_property("editable", True)
column_text = Gtk.TreeViewColumn("Text", renderer_text, text=0)
treeview.append_column(column_text)
renderer_editabletext = Gtk.CellRendererText()
renderer_editabletext.set_property("editable", True)
column_editabletext = Gtk.TreeViewColumn("Editable Text",
renderer_editabletext, text=1)
treeview.append_column(column_editabletext)
renderer_editabletext.connect("edited", self.text_edited)
self.add(treeview)
def text_edited(self, widget, path, text):
self.liststore[path][1] = text
def on_toggle(self, cell, path):
print "Toggled"
win = CellRendererTextWindow()
win.connect("destroy", Gtk.main_quit)
win.show_all()
Gtk.main()
以下是此代码的输出:
当我尝试编辑单元格时,它显示如下:
我想要的是,我希望减小编辑单元格时出现的编辑框的大小,因为它与行的其他单元格重叠,我希望该编辑框出现在其列宽内。注意我没有'我想按此顺序影响列或单元格大小。
我尝试设置各种属性,例如:width
,width-chars
,max-width-chars
等。
max-width-chars显示了一些影响,但随后它也减小了列的大小。
之前它发生在gtk2中,但在Gtk3 +中它显示出这种影响。
有人对此有任何解决方案吗?我真的很困惑。
答案 0 :(得分:0)
gtk单元格渲染器文本的编辑框有一些固定的宽度。
因此,当您使用一些空格分配每个列时,编辑框的重叠将不会发生。
在你的代码中,我简单地增加了窗口大小的宽度,这样,cellrendererText就可以获得足够的空间来打开编辑框而不会与其他框重叠
