The non-LCL one must simply call checksynchronize as the blocking part of the mainthread's eventloop.
Thus, my wish already seems to be fulfilled.
Great !
there is no LCL dependence in theory, but other eventloop systems might assume they themselves implement the blocking part. (e.g. to wake up because of OS messages) Services, console network server implementations etc probably already do that both on Delphi and Lazarus.
In fact the LCL seems to rely on the "It blocks for a maximum time" (as you said).
While this might be "good enough" for GUI events, there might be instances where we either would want either (1) a faster reaction (than the said "maximum time") on events that are not to be pushed through the RTL event queue or (2) avoid the processor overhead that is imposed by the main thread leaving the block after the "maximum time".
Regarding (2), I suppose it would be just nice to be able to define this time (I need to check the sources or the docs to find out).
Regarding (1), I suppose this will be a really rare request (not even required by my foreseeable queer projects). I would rather do this kind of stuff in worker threads and use TThread.Queue (which hurray !!! is available since some time) to schedule main thread actions.
Thanks a lot ! -Michael _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
