c# - Sharing KeyHandlers from MainWindow with a UserControl -


i have usercontrol has few previewkeydown event listeners, move these listeners mainwindow work not when usercontrol active focus, there way achieve this?

the reason have them in usercontrol action of previewkeydown event depends on tabitem selected in usercontrol.

you can handle previewkeydown @ mainwindow level , keydown , usercontrol level. best handle preview events @ container level grid/stackpanel etc. because @ window level many preview events reached various controls.

<window x:class="wpfusercontrol.mainwindow"         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"         xmlns:uc="clr-namespace:wpfusercontrol"         title="mainwindow" height="605.263" width="701.316" previewkeydown="window_previewkeydown">     <grid>         <grid.rowdefinitions>             <rowdefinition height="103*"/>             <rowdefinition height="217*"/>         </grid.rowdefinitions>         <uc:usercontrol1 background="aqua"/>     </grid> </window>

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
