Comment afficher, masquer, déplacer ou redimensionner le clavier à l'écran
Vous pouvez utiliser les messages Windows pour manipuler le clavier à l'écran.
Comme ceci :
WM_CSKEYBOARD = WM_USER + 192;
WM_CSKEYBOARDMOVE = WM_USER + 193;
WM_CSKEYBOARDRESIZE = WM_USER + 197;
// to show keyboard
PostMessage(FindWindow('TFirstForm', 'CKeysFirstForm'), WM_CSKEYBOARD, 1, 0);
// to close keyboard
PostMessage(FindWindow('TFirstForm', 'CKeysFirstForm'), WM_CSKEYBOARD, 2, 0);
// to fade keyboard
PostMessage(FindWindow('TFirstForm', 'CKeysFirstForm'), WM_CSKEYBOARD, 3, 0);
// to toggle (show/hide) keyboard
PostMessage(FindWindow('TFirstForm', 'CKeysFirstForm'), WM_CSKEYBOARD, 4, 0);

Si vous écrivez un logiciel de kiosque en HTML, vous pouvez utiliser les fonctions JavaScript spéciales pour contrôler le clavier à l'écran.
Avec JavaScript, vous pouvez afficher, masquer ou déplacer le clavier. Utilisez simplement les fonctions JavaScript spéciales pour ajouter des informations relatives au clavier à la légende du navigateur, et l'application surveillera la légende pour détecter les modifications.

WM_CSKEYBOARDMOVE : résolution du problème de déplacement du clavier lors de l'utilisation de plusieurs écrans avec des DPI différents.
Par exemple, l'écran 1 a une résolution de 2 560 x 1 440 et est réglé sur une « échelle de 125 % ». dans les paramètres d'affichage de Windows. L'écran 2 mesure 1 920 x 1 080 et est réglé sur « échelle 100 %.
Ouvrez les paramètres de compatibilité de l'application Windows 10 du fichier CKeys.exe et définissez le comportement DPI sur « Application », ce qui signifie que l'application gère tous les calculs liés au DPI. Avec ce paramètre activé, vous pouvez transmettre les valeurs de pixels physiques à la fonction de déplacement de votre API, et la fenêtre du clavier est ensuite déplacée exactement vers cette position.
Si vous souhaitez activer ce mode de compatibilité par programme (par exemple avec votre propre programme d'installation), vous devez définir la clé de registre suivante :
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers:
"C:\Program Files\ComfortKeys\CKeys.exe"="~ HIGHDPIAWARE"
Cela s’appliquera alors à tous les utilisateurs. Vous pouvez également placer cette clé dans le registre de l'utilisateur actuel (HKCU).
