How to embed third-party apps into QT application?

Hi,

I think you will have to play with something like the answer on this stack overflow post

Hi, thanks!
I have created a simple demo referring to this post.
Demo: EmbedExe
It can start "calc.exe", and "SetWindowPos" correctly.
The HWND of parent widget and child widget is right, but failed to "SetParent".

Debug output:
EmbedExe::onPushButtonClicked
Parent window: 0xc1014
Child window: 0xb126a
SetParent - ret 0x0

Could you help me please?
Best Regards!

Sorry, I currently can't as I don't have any Windows machine at hand.

@tovax What is the end goal? Are you wanting to automate something?

Hi,
I want to achieve the effect that all operations of the user must go through my application instead of directly operating the PC.
Prohibit users from operating PC, no automation required.

@SGaist
It doesn't matter, thanks.

Hi
would it not be easier to use windows features to lock down the pc and prevent a user from accessing the part of windows that you do not want ?

Hi,
Since there will be at least two operating systems in the future, win7 and win10, I wonder if win7 can use kiosk mode?
Best regards!

Test Results:

1. Use "createWidgetContainer":
   Embed external exe successfully, embedded window is active, but can't display the titlebar and menubar of the embedded window.
2. Use windows api "SetParent":
   Embed external exe successfully, but embedded window is inactive, and only can't display the menubar of the embedded window.

Hi
Actually win 7 will die in January 2020 :)

Anyway, win 7 does not have it as directly as win 10
but via group policy and a few tweaks. you can get the same sort of setup.

btw. i did try to use your demo code and have a look but i had no luck either.
The calculator would be its on window regardless.

Hi,
I don't know why the calculator of win10 can not be embedded, then I downloaded old calc version, and embed it successfully.
But the menubar disappearing. I wonder why the menubar doesn't show up.
This is the new repository (Use createWindowContainer)
NEW: EmbedCalc
Best regards!
