* QtConcurrent: mark as security-significantIvan Solovev2025-05-281-0/+1
| | | | | | | | | | | | | | | | | The QtConcurrent module applies user-provided map-, filter-, and reduce- functions (or their combinations) to user-provided data. It does not make any assumptions about the provided functions and data, apart from input/return type validation. It also does not parse the provided data and does not have any way to sanitize it. Mark all the source and header files in the module with the default security-significant score to confirm that the code was reviewed.

* doc: Fix all qdoc errors in QtConcurrentMartin Smith2017-12-081-0/+9
| | | | | | | | | | | | | These errors resulted from the improved parsing provided by clang, which required rethinking which elements of the QtConcurrent API should be visible to clangqdoc. The basic problem is that clang must see declarations for all types used by a type, or else it either gets lost and fails to parse a type correctly, or it simply refuses to include the type in its AST.

* Doc: Qt Concurrent: Link to essential usage informationTopi Reinio2015-04-071-0/+4
| | | | | | | | | | | | | | | | | | | | Functions under the QtConcurrent namespace used to be documented as header files, using the \headerfile command. These documents have been since converted to standard pages using the \page command, and the reference documentation for these functions now live in the namespace page only. However, the former pages contain useful usage information and code snippets, but they've not been linked to from anywhere. This change links to these pages from the module landing page, as well as from the function reference doc.
