Is there a Java API for touching devices such as tablets?

阅读更多关于 Is there a Java API for touching devices such as tablets?

问题 I'm a java developer and I love this techonology. However, in my advisor next research we are going to use extensively touch-screen devices on Windows . This is a problem for me, because I'm used to programming on Linux and with Java. The question is, is there an API for Java for touchscreen devices? If yes, is this API good/mature? The need for a Java API is not only because I love Java but because I don't know how to program specifically to Windows, that is, I've never used Win32 or .NET.

Get the co-ordinates of a touch event on Android

阅读更多关于 Get the co-ordinates of a touch event on Android

I'm new to Android, I've followed the hello world tutorial through and have a basic idea of what's going on. I'm particularly interested in the touch screen of my T-Mobile Pulse so just to get me started I want to be able to write the co-ordinates of a tocuh event on the screen, so say the user touched the co-ordinate 5,2 - a textview on the screen would display that. At present I have a simple program that just loads an xml file which contains the textview I intend to write the co-ordinates in. Thank you in advance, I did Google for help and searched stackoverflow but everything I found

Simulating mouse input programmatically in OS X

阅读更多关于 Simulating mouse input programmatically in OS X

问题 Is it possible to simulate the actions of a mouse from a program in OS X? Specifically, the short version is that I'm trying to simulate a touchscreen using two webcams. So assuming I can get X,Y positions, can I send information to the OS as a mouse movement or click? Edit- Or if it's particularly easy in another operating system I'd be willing to consider that. 回答1: Yes, it is possible. You can use the Quartz Event Services to simulate input events. Assuming C, I wrote this quick example:

How can I make a jQuery UI 'draggable()' div draggable for touchscreen?

阅读更多关于 How can I make a jQuery UI 'draggable()' div draggable for touchscreen?

I have a jQuery UI draggable() that works in Firefox and Chrome. The user interface concept is basically click to create a "post-it" type item. Basically, I click or tap on div#everything (100% high and wide) that listens for clicks, and an input textarea displays. You add text, and then when you're done it saves it. You can drag this element around. That is working on normal browsers, but on an iPad I can test with I can't drag the items around. If I touch to select (it then dims slightly), I can't then drag it. It won't drag left or right at all. I can drag up or down, but I'm not dragging

How to use ADB to send touch events to device using sendevent command?

阅读更多关于 How to use ADB to send touch events to device using sendevent command?

I am trying to send touch events to a device using AndroidDebugBridge, so that I can do some basic automation for UI tests. I have followed the discussion in LINK . I am able to use sendevent to simulate touch on emulators, but unable to do the same on a device. Like in above link the emulator seems to send out 6 events for each touch ( xcoord, ycoord, 2 for press,2 for release) and it was easy to use this information to sendevents, but a getevent for the touchscreen for a device seems to generate far too many events. Has somebody managed to send touch from ADB to a device? Could you please
