#include <QDBus>| enum | CallMode { NoBlock, Block, BlockWithGui, AutoDetect } |
The QDBus namespace contains miscellaneous identifiers used throughout the QtDBus library.
This enum describes the various ways of placing a function call. The valid modes are:
| Constant | Value | Description |
|---|---|---|
| QDBus::NoBlock | 0 | Place the call but don't wait for the reply (the reply's contents will be discarded). |
| QDBus::Block | 1 | Don't use an event loop to wait for a reply, but instead block on network operations while waiting. This means the user-interface may not be updated until the function returns. |
| QDBus::BlockWithGui | 2 | Use the Qt event loop to wait for a reply. This means that the user-interface will stay responsive (processing input events), but it also means other events may happen, like signal delivery and other D-Bus method calls. |
| QDBus::AutoDetect | 3 | Automatically detect if the called function has a reply. |
When using BlockWithGui, applications must be prepared for reentrancy in any function.
