How to embed third-party apps into QT application?

[tovax]

I want to embed third-party apps (for example firefox.exe) into QT application, could you give me some suggestions please?
QT: 5.12.4
PC: win10-64bit
I want to achieve the effect that all operations of the user must go through my application instead of directly operating the PC.

Best Regards!

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,

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?

Prohibit users from operating PC, no automation required.

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!
