Starting Frame.jpgnew display.jpg

Currently having trouble trying to figure out how best to approach this, currently I have a program that embeds another Qt Application using creatingwindowcontainer and fromwinid. However the program I wish to embed doesn’t start off in GUI mode (and instead starts off as a console application and only generates the form once it has received a message over socket comms).

So having trouble embedding this application from inside the other Qt Application (using QProcess), the embedding works fine however it doesn't fill the whole area and instead leaves the left and button sides in white(even when a stylesheet should be making it black) .

Below is my code for starting the process can anyone see any problems with what i’m trying to do, if anyone has any suggestions that would be great.

If anyone has any ideas what is going wrong that would be great, I have also uploaded two images one before the app is embedded and one for after with a red box to highlight the problem more clearly. Hope you someone can help. Thanks in Advance.
