c++ - How to manage separate GUI processes in a Qt application? -

-

how qt gui application start separate gui applications in different processes , managed windows?

let's have qt application call myapp. user able launch external application available on os within myapp run in own separate process. know qprocess, difficult part haven't been able figure out managing windows. myapp need have it's own title bars windows , cross platform. if launch application, calculator on windows, how rid of os title bar , window frame os default one, , how manage position , geometry of window?

more details: idea able extend myapp, including 3rd parties, adding new services implemented in language , gui toolkit. also, if service crashes, shouldn't affect myapp or other services. use analogy, imagine if in visual studio editor implemented in c , gui in gtk, debuger in c++ , interface in qt, etc, , looked 1 piece.

from whatever got question , whatever qt know, qt not support handle other application(like changing position). have handle applications on different platform differently. i.e. if myapp in windows , run calculator program. can use winapis handle calculator app can use setwindowpos set pos, etc.

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
