enum | CallMode { NoBlock, Block, BlockWithGui, AutoDetect } |
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.
