Test du composant IFrame disponible sur Tour de Flex

**ref92** · 14/06/2012, 01h36

Bonjour à tous,

J'ai essayé de tester avec mon Flash Builder le composant IFrame disponible sur Tour de Flex (http://www.adobe.com/devnet-apps/flex/tourdeflex/web/ puis saisir "IFrame" dans la barre de recherche). Il y a deux mxml :

IFrame.mxml
IFrameDemo.mxml

J'obtiens bien un arbre dans le panel de gauche. En revanche je n'ai strictement rien dans le panel de droite, que je clique ou non sur les éléments de l'arbre.

Pourriez-vous m'expliquer pourquoi?

Merci par avance à tous.

Salut,

probablement car tu n'as pas modifié le fichier template html qui modifie quelques propriétés du swf (wmode et opacity de mémoire... ).

Bonjour, merci pour avoir répondu rapidement.

Sur http://www.communitymx.com/content/a....cfm?cid=e5141 j'ai trouvé la ligne de code à ajouter à la balise <object> :

<param name="wmode" value="opaque">

J'ai donc ajouté cette ligne à mon fichier index.template.html mais le contenu de ma page HTML ne s'affiche toujours pas..

En fait je ne savais pas à laquelle des deux balises <object> il fallait rajouter la ligne, alors que je l'ai ajoutée aux deux, ce qui me donne la balise <noscript> suivante :

Ok et à tout hazard tu n'aurais pas oublié le div qui accueille le contenu HTML ?

Peux t'on voir l'intégralité de ton template html ?

**ref92** · 14/06/2012, 13h35

Non je n'ai pas mis de div pour accueillir le contenu HTML. Faut-il le mettre dans le body? Mon index.template.html est le suivant

Si tu n'as pas de div alors forcement ... regarde le composant que tu utilises et essaye de comprendre comment il fonctionne.

Tu trouveras une multitude d'informations sur ce sujet ici ou sur un tas de site dédié à Flex.

Re-bonjour et merci pour les réponses.

J'ai réussi à faire apparaître mon IFrame. Le souci maintenant c'est que l'IFrame se place en haut à gauche de l'écran, et par-dessus les deux Panels, alors qu'il devrait se placer dans le second panel (j'ai mis en ligne une capture d'écran à l'adresse http://imageshack.us/photo/my-images/715/scaniframe.png).

Que dois-je faire pour que l'Iframe s'insère bien dans le second Panel?

Le code de mon IFrame.mxml est :
