Qt Modality Over Another Application?

[LiamMaru]

Bit of an odd question, but is there a way for one Qt application running in a different address space to give it's main window modality over another main window in another application? What sort of information is required by either application? HWND, window ID?

I'm interested in pushing certain functionality into DLL files or SO files (depending on the platform) and this is a significant concern.

Shared libraries share the address space of the executable using them, so pushing functionality into a library should not necessitate making one window modal to another applications window.

It is not possible to give memory from one process to another directly. The address spaces are separated. You can use some IPC mechanisms to communicate between them, but the resources stay in the process where they are.
