keyboard

问题 I would like to write an application to generate keyboard input (i.e. to the system it would look just like a button on the keyboard had been pressed) for a Linux system. I would like to use C and xdotools are not an option. Libevdev looks promising, but so far I haven't been able to get it to work. First, can libevdev do what I want? Most of the documentation is focused on reading the incoming input and outputting it, but the API does feature a function to "Post an event through the uinput

问题 I'm creating a virtual keyboard for a touchscreen Flex app and i'm trying to simulate a key press by dispatching a KeyboardEvent. I've written a handler function to listen for the event and act accordingly. So far so good... but it's starting to get complicated as i have to manage the focused textInputs (easy), the cursor position in those fields (not to so easy), etc. Now, if only there was a way to actually dispatch a KeyboardEvent that Flex would actually interpret as a genuine key press

问题 Consider an application where it's desirable to grab the keyboard when focused in order to capture all window manager commands (Alt+F4 and whatnot) for processing. Now, this has the downside that the user has no way of switching to another application or virtual desktop via the keyboard when the keyboard is grabbed. I'd like to have a user-defined whitelist of key combination (say, the key combinations for switching virtual desktops) that are excluded from the grab. I can think of two

问题 I use a UITextView for multiline text entry in my iPhone app, and I have set the "Return" key to display "Done." I've also set up the return key to disable first responder status, so that hitting "done" actually exits the UITextView. However, I also want to enable users to be able to enter multiline text into the UITextView, i.e. to be able to use the "Return" key. Is there any way to make this work on the iPhone/iPad's UI? 回答1: It'll be time consuming but you could create your own keyboard

问题 I use the 2.9.0 version of Phonegap and I want that when the keyboard appears my WebView shrinks like it's done in Android phonegap apps. I have footer and header elements in fixed position, and when the keyboard is open it causes trouble (the footer and header loose their fixed position state). I think the KeyboardShrinksView settings could fix that, according to the phonegap documentation : http://docs.phonegap.com/en/2.9.0rc1/guide_project-settings_ios_index.md.html#Project%20Settings

问题 I want to create a virtual keyboard in osx. Is it possible? I mean can I make a program that gives same signals than real keyboard. Example of this kind of keyboard would be onscreen keyboard, or keybord viewer (does it have necessary interface btw). How low should I start? Should I make a device driver e.g. virtual (wireless) keyboard? Or does cocoa etc. have the necessary stuff? The requirements I have are: - a list of tuples (time, key_down/key_up, key_code) corresponds to person typing -
