Windows : utilisation de la "Non-client area"

Bonjour,

je suis sous Windows 7 x64 et j'utilise PySide avec Python 3.

Par curiosité j'ai cherché à mettre en pratique la technique employée ici http://msdn.microsoft.com/en-us/libr...=vs.85%29.aspx qui permet d'enlever la zone non cliente d'une fenêtre sous Windows tout en conservant les boutons de la barre de titre.

J'ai donc cherché à intercepter les messages de la sorte

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

from PySide.QtGui import QApplication, QWidget   class Window(QWidget): def __init__(self): QWidget.__init__(self)   def winEvent(self, msg, result): print(msg) return QWidget.winEvent(self, msg, result)   if __name__ == '__main__': app = QApplication([]) win = Window() win.show() app.exec_()

---

mais je n'ai pas trouvé quoi que ce soit de très utile.

Le but final et de pouvoir implémenter ce fameux DwmDefWindowProc qui permet d'avoir les boutons de la barre de titre fonctionnels tout en ayant la possibilité de dessiner sur la totalité de la fenêtre (barre de titre inclue) un peu comme le font Chrome et Firefox.

Je sais également qu'il est possible d'intercepter les évènements de l'application au niveau de la QApplication mais j'aimerai éviter de ralentir le tout en faisant un hook depuis Python.

Si quelqu'un a une piste je suis preneur.

PS: Je sais que ce genre de technique n'est absolument pas portable mais c'est juste pour savoir si c'est possible.

P'têt que ceci repondra à ta question:

http://www.developpez.net/forums/d92...s/qt-dwm-aero/

Merci pour ta réponse.

Je vais tenter de convertir en Python et voir si ça donne quelque chose de concluant.

EDIT: J'ai essayé de convertir sans succès (trop de références à des fonctions issues de l'API win32).

J'ai également installé QtCreator et testé la librairie QDwm et ça ne fait pas exactement ce que je désire. Je mettrai à jour le sujet si j'arrive à quelque chose de concluant.

J'ai réussi à avoir quelque chose de fonctionnel (non sans bugs) mais uniquement avec PyQt4 car PySide a un bug et il manque des attributs au paramètre msg de la méthode winEvent (donc impossibe d'aller plus loin).

Voilà ce que ça donne en terme de code

si quelqu'un à une idée pour détecter dynamiquement les valeurs des bordures je suis preneur :)

EDIT: pour information, j'ai utilisé cet article http://technet.microsoft.com/en-us/query/bb688195

Bonjour,

ayant décidé de me pencher à nouveau sur le sujet, j'ai converti le code C++ disponible ici http://sourceforge.net/projects/qdwm/ en pur Python3/ctypes.

Le tout non exempt de bugs évidemment (ne marche pas sur Python2 par exemple).

Je précise également que je suis en x64 donc les appels ctypes sont peut-être incorrects.

Je marque ma question comme résolue.

EDIT: Ajout du code :oops:

Bonjour ashren,

Beau code, dont une ligne sur 2 contient des instructions que je connais pas :roll: .

Ce code semble fonctionner sur Windows 7 64 bits / Python 2.7 si le but est d'obtenir une fenêtre avec un gros bouton qui prend toute la zone cliente, et une barre haute anormalement grande. Par contre, quand je clique sur test, il ne se passe rien.

Le bouton est juste là pour tester si le contenu reste bien à sa place ^^.

J'avais testé avec Python 2.7 et la fenêtre était noire (pas transparente).

Pour les instructions inconnues, ben ... c'est porté brut de décoffrage du C++ sans refactoriser de manière plus pythonique. Et il faut avouer que l'utilisation de ctypes n'aide pas.

PS: Il y a forcément des bugs (j'ai passé plus de 3h dessus et j'étais plus trop frais après).

HS: Sinon pour ceux que ça intéresse, j'ai un bout de code pour réparer la fonctionnalité QWidget.winId() de PySide (utilisation de ctypes également).
