howto run commonqt asynchronously
by Orm Finnendahl 28 Dec '15

28 Dec '15

Hi, I'm looking for a common lisp tool to open multiple gui windows on the fly from the repl for realtime musical applications, like synth modules or graphs for displaying waveforms with cursors moving above them. I haven't found any documentation on this, but my tests seem to indicate that a commonqt application blocks the repl and only one qtapplication can be run at a time. Is there an easy solution for this? I have used mcclim before and it was possible there as every application-frame has its own repl, but I fear mcclim doesn't have the same performance as qt. -- Orm

So ... After having spent the better part of this day getting CommonQt to tun on OS X there's a couple of points to note: Do not follow any other info than that on CommonQt's Homepage. It will cause you trouble, especially if you are on OS X. ;-) The other point is related to the thread challenge I encountered. And yes, multi-threaded SBCL is able to run CommonQt on OS X if 1. You change file repl-integration.lisp line 106 from "initial thread" to "main thread" and recompile and reload the qt package. 2. You don't use Slime to interact with your REPL. The second is a real PITA. So I tried digging up a solution. The qt-repp package seemed the right thing to use. Nope: (ql:quickload :qt-repl) (qt-repl:start-gui-thread) Lisp output: WARNING: QApplication was not created in the main() thread. Using qt-repl:eval-in-gui-thread (with the mods described above) then tries to execute the evaluation in the guy thread. But no, this doesn't work: Lisp output: QCoreApplication::exec: The event loop is already running Slime repl output: CL-USER> (qt-repl:eval-in-gui-thread (qt-conv:main)) -1 and that's where I am stuck now. Further digging or suggestions are in order ;-) Thanks to Stas and Ivan for the support so far! Regards Frank

[Commonqt-devel] Qt Tutorial: Memory Fault
by Frank Goenninger 26 Apr '14

Me again ... Doing (ql:quickload :qt) (qt:ensure-smoke :qtcore) (qt:ensure-smoke :qtgui) (ql:quickload :qt-tutorial) and finally (qt-conv:main) results in the following errors: SBCL error output: http://paste.lisp.org/+31SS SBCL backtrace: http://paste.lisp.org/+31ST Ok, so maybe I am running into issues as described on "Known issues", "Callbacks from threads" - am I? Thanks again for looking at this. Regards Frank

Make sure that libsmoke and >libcommonqt were compiled and are using the same version of Qt. Maybe I'm misinterpreting something, but this line 1: ("foreign function: call_into_lisp") from the backtrace as shown in the lisp paste is a callback from C to Lisp for me. And right in that function hell starts ... To be honest I haven't looked at the sources of Qt yet (I don't have them installed as my disk space is a scarce resource). I am still hoping for someone having had the same problem. Thanks again for helping out. Kind regards Frank

[commonqt-devel] Signal arguments of user defined Lisp types
by Chong Kai Xiong 29 Jan '14

29 Jan '14

Hello list, Is it possible to define Qt signals that have arguments of user-defined Lisp types e.g. structures? I tried the signature "move(coord,coord)", where "coord" is a Lisp structure representing a pair of board coordinates but SBCL 1.1.14 throws the runtime error: "No smoke type found for dynamic member arg type coord. Giving up." Perhaps this could be done using a Smoke recognised type such as QPoint, but I would like to know the answer to the general question. Thanks, Kai Xiong

[commonqt-devel] Qt Tutorials
by Greg Bennett 17 Dec '13

Hello there, I have acquired common-qt and will try to work my way through translating the Qt tutorials. [These can be accessed from http://common-lisp.net/project/commonqt/ by running down to the Examples paragraph and right-clicking on the Qt tutorial link.] tutorial1 has me puzzled already. Its objective is to create a push button holding dear old Hello World! The C++ source code shows that its approach is to build the object out of sight, and them display it; the translation of tutorial14 (also reachable from common-qt's home page) kindly supplied by David Lichteblau and Stas Boukarev use clos as the logical improvement on c++ classes. I presume that a purpose of the set of tutorials is to make one familiar with this way of structuring code. I am running ccl Version 1.9-r15975M (LinuxX8664) under Linux Mint 14 (64bit) on an HP box. Having loaded commonqt, and issued the requisite (named-readtables:in-readtable :qt) I thought I would see whether I could create the button in the repl before dealing with the structuring. Some poking about in Qt's own documents [for Qt4.8, since that is the version recommended] led to (with-main-window (window (#_new QPushButton "Hello World!"))) This does produce the desired button, with the letter "a" where a title would go. It's part of argv0dummy, it seems. I notice, with some interest, that the Qt c++ code shows a result with "t1" as the window's title without any mention of t1 in the code itself. More poking led me to the function setTitle associated with QWindow, which appears to take a QString as argument, and thus to (with-main-window (window (#_new QPushButton "Hello World!")) (#_setTitle window (#_new QString "t1"))) from which I received Error: Class not found: QString. Back to the docs, and on the Qt side I would have needed #include <QString> before using one. Then I realised that I don't know how to get access to such Qt-packages on the fly inside commonqt. Evidently there are some/many which do not come with (ql:quickload :qt). Pointers to how to get access to QStrings, and how to learn about how to do so without having to ask the list would be appreciated. The joys of converting repl -> clos await me! With thanks for your patience, Cheers /Greg Bennett

[commonqt-devel] new user queries

Hello there .. I am running linux mint 14 (64 bit) and clozure (ccl 1.9-r15972M), and have just installed commonqt, as well as many non-lisp necessities on the qt side. I am a tad stuck in trying to use commonqt, and would appreciate a pointer to assistance. (1) In trying to run the example pointed to on the page http://common-lisp.net/project/commonqt/#main-window as the lisp version of the currency-conversion code, and thus in a package which apparently references qt, in a fresh ccl I am told that there is no with-main-window function. This string is also referred to as a macro on the above page. It would seem that I am missing it, so a pointer to its definition would be helpful. (2) Way down in a git clone, where commonqt lives, there is a test subdirectory containing 3 files, one of which is package.lisp which holds only this definition: (defpackage :qt-tests (:use :cl :rt :qt :iterate)) The package qt-tests is the one within which the tests.lisp code is to run. Issuing the above defpackage -> Error There is no package named "RT" so, again, I seem stuck for lack of knowledge. Thanks for any and all assistance. Cheers /Greg Bennett
