The Windows Live Messenger is just one example where Windows 7 doesn’t create a new set of UIs just for touch scenarios, but instead makes it blend into the existing infrastructure. The spacing between each item in the multitouch-enabled Jump List is larger than the spacing between each item in the left image, which is the default right-click Jump List.įigure 2 Multitouch and Standard Views of Jump Lists The right-side image shows the Live Messenger’s Jump List using touch. As you can see in Figure 2, the touch-triggered Jump List displays the same content as in the standard right-click Jump List. Performing that drag gesture shows Live Messenger’s Jump Lists. But how can you right-click using multitouch? Simply touch the Live Messenger icon and drag out with your finger, as shown in Figure 1.įigure 1 Using Multitouch on Live Messenger’s Jump List For example, right-clicking on the Windows Live Messenger icon shows Live Messenger’s Jump List. When you use the mouse to right-click on any icon on the Taskbar, you see its corresponding Jump List. The simplest example is the Windows 7 Taskbar Jump Lists. There is no special Windows Explorer that is available only on multitouch devices. It is important to understand that we didn’t create a special Windows 7 Multitouch Shell. For example, you are able to reach out and slowly scroll through your pictures directly from Windows Explorer, or flick and move through them quickly. With the Windows 7 Multitouch Platform, you have the freedom to directly interact with your computer. Therefore, it is only natural for Windows to introduce such multitouch support in Windows 7 as a core capability. In recent years, we have witnessed a wide range of multitouch devices that have generated an extremely positive user experience. In Windows 7we have enriched the Windows experience with touch, making touch a first-class citizen as another way to interact with your PC alongside the mouse and keyboard.

The series focuses on new user experiences that developers can tap into to make their applications shine on Windows 7. This is the third article in a series of articles about Windows 7. Windows 7 Multitouch Platform Programming Models This article is based on a prerelease version of Windows 7.

I can't comment too much on the lag you're talking about because I don't know the nature of the lag you're seeing. * The driver will look for a config file in /system/vendor/firmware, upon starting up * If you're doing this for Android, you'll need an. The driver formats the data and forward that up to the user space via the input subsystem. When a touch/drag happens, objects will be sent to the driver to process. ![]() ![]() * The driver has an interrupt routine handling the /CHG line. You will need to set up pinmuxing for this pin as well. * The IC will also have a /CHG line that will go low when it has data to send to host. May need pinmuxing to set the functionality of the pin correctly. * Typically, there's a reset line that has to be pulled high on the board. This structure has some configuration data needed by the driver * The driver has a structure that needs to be setup from your board file (example arch/arm/mach-omap2/board-?.c). * In the case of the mxt224/336, the driver needs the I2C driver Objects from the host to the IC are typically configuration data, and objects from the IC are probably touch data To understand what the objects are, you'll need to find the datasheets/manual for the chip you're using. * The driver allows the exchange of "objects" between the touch IC and the host processor. Some high level info for you to get started: I've looked at the mxt224/mxt336, so the following info is specific to those. ![]() Luckily, these drivers are small, the mxt224 is just a single C file. I don't think you'll be able to find a single place that describes the driver.
