私はボタンで自分のセルレンダリングを作成する必要があり、私はこの思い付いた:PythonとGTK 3でカスタムGtk.CellRendererを書くには?
#!/usr/bin/env python3
from gi.repository import Gtk
class CellRendererButton(Gtk.CellRenderer):
def __init__(self):
Gtk.CellRenderer.__init__(self)
def get_size(self, widget, cell_area):
buttonHeight = cell_area.height
buttonWidth = buttonHeight
return (0, 0, buttonWidth, buttonHeight)
def render(self, window, widget, background_area, cell_area, expose_area, flags):
style = widget.get_style()
x, y, buttonWidth, buttonHeight = self.get_size()
style.paint_box(window, widget.get_state(), Gtk.SHADOW_ETCHED_OUT, expose_area, widget, None, 0, 0, buttonWidth, buttonHeight)
class MyWindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title = 'T', default_width = 200, default_height = 300)
self.connect('destroy', self.__onDestroy)
self.__createGUI()
self.show_all()
def __createGUI(self):
box = Gtk.Box(orientation = Gtk.Orientation.VERTICAL)
listStore = Gtk.ListStore(str, str)
treeView = Gtk.TreeView(listStore)
textRenderer = Gtk.CellRendererText()
textColumnA = Gtk.TreeViewColumn(None, textRenderer)
textColumnB = Gtk.TreeViewColumn(None, textRenderer)
buttonRenderer = CellRendererButton()
buttonColumn = Gtk.TreeViewColumn(None, buttonRenderer)
textColumnA.add_attribute(textRenderer, 'text', 0)
textColumnB.add_attribute(textRenderer, 'text', 1)
treeView.append_column(textColumnA)
treeView.append_column(textColumnB)
treeView.append_column(buttonColumn)
listStore.append(('my string', 'my string'))
self.add(treeView)
def __onDestroy(self, e):
Gtk.main_quit()
t = MyWindow()
Gtk.main()
が、そのは動作していない:私は何かが欠けてい
(game.py:4736): Gtk-CRITICAL **: gtk_cell_renderer_render: assertion `GTK_CELL_RENDERER_GET_CLASS (cell)->render != NULL' failed
:/私のようなエラーの多くを得ます?私はそれを動作させるために何かすべきことがありますか?
