pygobject 创建拖放源
from gi.repository import Gtk, Gdk
def drag_data_get_cb(widget, drag_context, selection_data, info, time):
print selection_data.get_data_type()
print widget.get_text()
return widget.get_text()
def drag_begin_cb(widget, dragcontext):
print dragcontext, widget
return dragcontext
label = Gtk.Label()
label.drag_source_set(Gdk.ModifierType.BUTTON1_MASK, [], Gdk.DragAction.COPY)
label.set_text("Drag Me!")
label.connect("drag_data_get", drag_data_get_cb)
label.connect("drag_begin", drag_begin_cb)
window = Gtk.Window()
window.add(label)
window.connect("delete_event", Gtk.main_quit)
window.set_default_size(300, 250)
window.show_all()
Gtk.main()
这几天我一直在用头撞墙, 谁能告诉我为什么这不允许我将文本拖动到其他小部件中?两个拖动事件都没有触发
from gi.repository import Gtk, Gdk
def drag_data_get_cb(widget, drag_context, selection_data, info, time):
print selection_data.get_data_type()
print widget.get_text()
return widget.get_text()
def drag_begin_cb(widget, dragcontext):
print dragcontext, widget
return dragcontext
label = Gtk.Label()
label.drag_source_set(Gdk.ModifierType.BUTTON1_MASK, [], Gdk.DragAction.COPY)
label.set_text("Drag Me!")
label.connect("drag_data_get", drag_data_get_cb)
label.connect("drag_begin", drag_begin_cb)
window = Gtk.Window()
window.add(label)
window.connect("delete_event", Gtk.main_quit)
window.set_default_size(300, 250)
window.show_all()
Gtk.main()
ive been hitting my head against a wall over this for a few days now,

在此教程中指出,您无法在没有窗口的情况下使用小部件,例如
Gtk.Label
作为拖放源。例如,您可以用按钮替换标签:为了使该示例正常工作。
It says in this tutorial that you cannot use widgets without windows, such as
Gtk.Label
as drag and drop sources. You can replace the label with a button for instance:in order for this example to work.
