我花了很多年尋找一種方法來做到這一點,我迄今爲止沒有任何東西。 :(蟒蛇,快速和林間空地,在TextView中顯示標準輸出
我想爲我製作的一個小小的CLI程序製作一個圖形用戶界面 - 所以我認爲使用Ubuntu的「快速」將是最簡單的方法,基本上它似乎使用Glade製作GUI。我知道我需要在一個子進程中運行我的CLI後端,然後將stdout和stderr發送到一個textview,但我不知道如何做到這一點。我想要的輸出出現在對話框中:
from gi.repository import Gtk # pylint: disable=E0611
from onice_lib.helpers import get_builder
import gettext
from gettext import gettext as _
gettext.textdomain('onice')
class BackupDialog(Gtk.Dialog):
__gtype_name__ = "BackupDialog"
def __new__(cls):
"""Special static method that's automatically called by Python when
constructing a new instance of this class.
Returns a fully instantiated BackupDialog object.
"""
builder = get_builder('BackupDialog')
new_object = builder.get_object('backup_dialog')
new_object.finish_initializing(builder)
return new_object
def finish_initializing(self, builder):
"""Called when we're finished initializing.
finish_initalizing should be called after parsing the ui definition
and creating a BackupDialog object with it in order to
finish initializing the start of the new BackupDialog
instance.
"""
# Get a reference to the builder and set up the signals.
self.builder = builder
self.ui = builder.get_ui(self)
self.test = False
def on_btn_cancel_now_clicked(self, widget, data=None):
# TODO: Send SIGTERM to the subprocess
self.destroy()
if __name__ == "__main__":
dialog = BackupDialog()
dialog.show()
Gtk.main()
如果我把這個在finish_initializing功能
backend_process = subprocess.Popen(["python", <path to backend>], stdout=subprocess.PIPE, shell=False)
然後進程啓動並作爲另一個PID運行,這是我想要的,但現在如何將backend_process.stdout發送到TextView?我可以寫到textview:
BackupDialog.ui.backup_output.get_buffer().insert_at_cursor("TEXT")
但我只需要知道如何讓這個被稱爲每次有一個新的標準輸出行。
