Android 3.0 Use Physical Keyboard Setting

由 限于喜欢 提交于 2020-01-15 08:08:24
问题 Background: I recently purchased a Motorola XOOM Tablet along with the Desktop Dock and Bluetooth Keyboard accessories. The dock and keyboard work great, but when I take the tablet off the dock to move away from my desk, the keyboard still remains paired with the device and I have to manually change the settings to use the soft keyboard. The same goes for when I set it back on the dock, I need to manually switch it back. It's not a huge problem, but it would be nice not to have to think about

MacOS Virtual Input Devices

问题 How can I create a virtual HID device in code? I'm trying to avoid writing a kernel extension to accomplish this, but it seems to be the only way. I need to be able to create virtual HID devices of all types, and have an app running in the background feed them events. Is there a way to do this in user-space, or must I venture into kernel land? 回答1: The typical way of creating HID devices is to use the IOHID* classes in IOKit. You can write a userclient that passes events in and out. I'm not

The typical way of creating HID devices is to use the IOHID* classes in IOKit. You can write a userclient that passes events in and out. I'm not sure what a "virtual" HID device is, however, I guess. If you want to create a keyboard on the screen, that

问题 I connect bluetooth barcode scanner to my android tablet. barcode scanner is bonded with android device as a input device - HID profile. it shows as keyboard or mouse in system bluetooth manager. i discovered that bluetooth profile input device class exist but is hidden. class and btprofile constants have @hide annotaions in android docs. hidden class: http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.3.1_r1/android/bluetooth/BluetoothInputDevice.java here

How can you take ownership of a hid device?

由 女生的网名这么多〃 提交于 2019-12-03 03:47:51
问题 What I would like to take ownership of a hid device that may already have been plugged in, consume it's output, while preventing others(X11 or terminal) from consuming it. If I can help it, I don't want to pretend to be a terminal, but rather to monopolize a particular hid or character device. The idea is that some hid devices may be recognized as mice/keyboards by x/terminal, but a second mouse or keyboard could be used for something else, but to do that you need to make sure they aren't

Make a USB Device, Control It In Java

I'm thinking about making a physical controller (device?) with knobs, buttons, and LEDs. I'd like to interact with it using Java (respond to the knobs, light up LEDs, etc). The reason I mention Java is two-fold: first, I know Java well 1 . Second, I've written the rest of the program I need to interface with in Java (though there are ways to talk to the Java program from another language). I would like the device to connect via USB and be (computer-)platform independent. I haven't the slightest idea of where to start, except to start reading the Arduino website. Is this my best/only option? Is

JavaScript: Check if mouse button down?

由 走远了吗. 提交于 2019-11-26 12:07:44
Is there a way to detect if a mouse button is currently down in JavaScript? I know about the "mousedown" event, but that's not what I need. Some time AFTER the mouse button is pressed, I want to be able to detect if it is still pressed down. Is this possible? Eugene Lazutkin Regarding Pax' solution: it doesn't work if user clicks more than one button intentionally or accidentally. Don't ask me how I know :-(. The correct code should be like that: var mouseDown = 0; document.body.onmousedown = function() { ++mouseDown; } document.body.onmouseup = function() { --mouseDown; } With the test like
