I am using a template from manpce/XPCE examples/Menu Bar
message(V, load, @finder?file)) don’t open the file viewer
get(@finder, file, @on, *, File) do it easily but I cannot use get
Obviously it is waiting for arguments (@on *) but just see @default/constant.
So how to to pass arguments to finder object file method ?
Default file at xpce root seems to work only for class variables.
Also this makes Prolog crashing:
trying to trace with guitracer
opening edit. , compile buffer and execute → Prolog crash
no crash if I compile from console.
Win10 64 bits tested with last Prolog stable release 32 and 64 bits.
thanks for your help.
There was bug in the finder for dealing with an unspecified (default mode). Pushed a fix. That should be in tomorrows daily download. It will take quite a while before a next stable version is released.
The xpce gui system is more or less end-of-life. It is likely to be maintained for quite a while, but nothing was improved since many years. To make the example work you must add
at the top and start using initialization/1 rather than using :- directly:
As for the crash, that is mostly likely related to xpce which by default runs the tools in a thread (called pce). Part of the IDE running in a thread and your application started from the main thread is likely to give problems. Use
:- set_prolog_flag(xpce_threaded, false).
before anything graphic related, i.e., before loading library(pce). When in doubt, run
to check the running threads. When developing an application using xpce this should list main and (probably) gc, but notpce.
