UNE FENÊTRE QUI SE SAUVE QUAND ON PASSE DESSUS, STOPPE CTRL-ALT-SUP

lut !
je cherche un truc similaire : il faut que je fasse une barre d'outil qui se trouve à gauche d'une fenêtre (un peu comme dans Acrobat Reader) qui se cache quand elle est inactive et qui s'agrandit quand on pointe le curseur dessus.
J'ai un début de code qui utilise un Tab ainsi que les méthodes que tu as données.
Malheureusement ça marche pas 'top' surtout la perte de focus. Mais je suis un débutant de chez débutant (quelques semaines) et je sais pas trop quels évènement je doit gérer pour améliorer le système de focus...
