Previously, individual components had to ask the peer to hide and show the keyboard, by calling textInputRequired() and dismissPendingTextInput() respectively. When an onscreen keyboard (OSK) was required, most Peer implementation would directly hide/show the OSK inside these function. However, the iOS ComponentPeer implementation instead listened to the application's global keyboard focus, and only opened the OSK when the focused component was also a TextInputTarget with active input. The iOS scheme seems like a better design, as it enforces that the OSK hiding and showing is synced with the keyboard focus of the application. In the other implementations, it was possible for a Component to call textInputRequired even when it didn't have the keyboard focus, putting the application into an inconsistent state. The iOS scheme also makes the TextInputTarget interface more useful, as it enforces that the OSK will only display for components that implement TextInputTarget, and return true from isTextInputActive(). This patch changes all Peer implementations to match the iOS implementation, improving consistency. Each time the global keyboard focus changes, refreshTextInputTarget is called automatically, and the OSK is shown if the focused component is a TextInputTarget that returns true from isTextInputActive, and hidden otherwise. Components can also call refreshTextInputTarget manually. This should be done whenever the component updates the return value of isTextInputActive(). Effectively, the Peer is now responsible for keeping track of the focused TextInputTarget, rather than allowing individual components to hide and show the OSK at will. Additionally, this patch adds an option to the TextEditor to automatically dismiss the OSK when the mouse is clicked outside of the editor. This should improve user experience on mobile platforms, where touches on sibling components may cause a TextEditor to gain keyboard focus and unnecessarily display the OSK. |
