Threads et Perl/Tk

Salut Merci pour l'article. J'ai essayé d'utiliser votre script dans mon application GUI.
Actuellement, je suis confronté à un problème. Je ne suis pas en mesure d'appeller la fonction qui est dans le thread.
exemple:
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 sub run_script_tk { if ($paste_text) { $FunctionName = "run_script"; # He says the procedure to call @ArgumentsThread = ($paste_text); # He is given the arguments $ThreadWork = 1; # Asked to work # ===> Modification (Rajout) <============= # Button is deactivated List Files #$run_button->configure(-state => "disabled"); # As long as the thread work, we expect while ( $ThreadWork == 1 ) { sleep 0.2; $f ->update; } # It reactivates the List Files button $run_button->configure(-state => "normal"); } return; }
Il mentionne une erreur disant

Citation:

valeur invalide à la variable partagée

à

Code:

$FunctionName = "run_script";

Je ne suis pas en mesure d'attribuer un nom de fonction à la variable partagée

votre aide est très appréciée. Je travaille sur Ubuntu pour mon interface graphique.

Dans l'article, il est bien mentionné de déclarer les variables nécessaires et à partager en début de programmes. J'ai l'impression que vous n'avez pas bien lu ou compris l'article (surement à cause de la langue). Il faudrait nous montrer votre code plus complet.

Threads & TK

J'ai bien compris votre article! J'ai partagé toutes les variables.
Voici mon problème, j'ai créer une image de boutons dans le cadre.
Je veux faire de ce boutons d'image multithread. Lorsque j'ai
assigner les arguments et le nom de fonction pour varibles partagé
Je reçois le problème. J'ai inclus un morceau de code de ma
application. S'il vous plaît analyser et si vous avez des doutes faites le moi savoir.

Premièrement, dans tout script Perl, je vous recommande de toujours utiliser les modules suivant :

Code:

1
2
use strict;
use warnings;

Cela vous éviterez d'avoir des erreurs de syntaxes comme

Code:

my $FunctionName : shared; l

ou des soucis de placements de codes

Salut je résolu le problème de la création du fil. Mais j'ai un nouveau problème.
Ci-dessous je vais essayer d'expliquer le problème:

1. J'ai créé un thread pour un sous-programme(procedure)
2. Dans ce sous-programme que je veux faire une telle déclaration:

Code:

do "addcontact.pl"

Le fichier Perl est externe.
3. Je n'ai pas fait ce fichier Perl partagée.
4. Quand j'appelle ce fil (sous-programme-procedure), le fichier ne s'exécute pas

Comment puis-je résoudre ce problème? Comment faire de ce fichier Perl comme ils partagés?

Merci pour votre temps.

Peux-tu nous montrer le code ?

C'est la routine pour laquelle j'ai créé le fil.

le reste du code est le même que dans le post précédent. Le seul problème, je suis confronté est que je ne suis pas appeler le fichier externe perl dans ce sous-programme. C'est ainsi que pour faire de ce fichier partagé!

Code:

do "addcontact.pl";

est censé faire quoi ?
A quoi correspond le mot do ?
Lorsque tu enlèves la ligne

Code:

do "addcontact.pl";

, est-ce que le reste fonctionne ?
16/07/2011, 22h39
mahis431

le mot do c'est comme use.

do - c'est une fonction
require - est également une fonction

(use = do = require) mais il ya une certaine différence entre les deux

Oui, il fait le reste du travail mais ne sera pas appeler le do
16/07/2011, 23h39
djibril

do est généralement utilisé pour effectuer des boucles : until et while, néanmoins, on peut l'utiliser comme require; Mais bon, il faut éviter cette façon de programmer, je ne trouve pas ce mode de programmation approprié.

Pour revenir, à ton souci, si le do charge le contenu du script addcontact.pl, tu te retrouves avec du code Perl non partagé, ce qui ne fonctionnera pas. Il faut donc revoir ton algorithme pour procéder différemment.
