Python – GTK+ 3 中的 CellRendererText

Gtk.CellRenderer 小部件用于在小部件中显示信息，例如Gtk.TreeView或Gtk.ComboBox 。下面是用于不同目的的七个Gtk.CellRenderer小部件。

  • Gtk.CellRendererText
  • Gtk.CellRendererToggle
  • Gtk.CellRendererPixbuf
  • Gtk.CellRendererCombo
  • Gtk.CellRendererProgress
  • Gtk.CellRendererSpinner
  • Gtk.CellRendererSpin
  • Gtk.CellRendererAccel

在本教程中，我们将讨论Gtk.CellRendererText 。 Gtk.CellRendererText使用其属性提供的字体、颜色和样式信息在其单元格中呈现给定文本。

Gtk.CellRendererText小部件中的文本可以通过以下方式进行编辑

cell.set_property("editable", True)

例子 ：

Python3
from gi.repository import Gtk
import gi
  
gi.require_version("Gtk", "3.0")
  
  
class CellRendererTextWindow(Gtk.Window):
    def __init__(self):
        Gtk.Window.__init__(self, title ="Geeks For Geeks")
  
        self.set_default_size(400, 400)
  
        self.liststore = Gtk.ListStore(str, str)
        self.liststore.append(
            ["Python Archives", "https://www.geeksforgeeks.org/category/programming-language/python/"])
        self.liststore.append(
            ["Python-GTK Archives", "https://www.geeksforgeeks.org/tag/python-gtk/"])
        self.liststore.append(
            ["Data Structures Archives", "https://www.geeksforgeeks.org/category/data-structures/"])
        self.liststore.append(
            ["Algorithms Archives", "https://www.geeksforgeeks.org/category/algorithm/"])
  
        treeview = Gtk.TreeView(model = self.liststore)
  
        renderer_text = Gtk.CellRendererText()
        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
  
  
win = CellRendererTextWindow()
win.connect("destroy", Gtk.main_quit)
win.show_all()
Gtk.main()
