Here, if you have Synaptics TouchPad equipped computer like laptop, you are about to get something similar. The new Synaptics Gesture Suite device driver is now equipped with Scrybe gesture workflow technology , meaning that you can finally experience the scrolling, zooming, and rotating gestures on your TouchPad equipped computer. It supports to almost all Windows Operating System, including Windows 7, both 32bit and 64bit.
Once you have the drive loaded and have your computer restarted, you are ready to rock. Open action center: Tap four fingers on the touchpad. Switch virtual desktops: Place four fingers on the touchpad and swipe right or left.
Windows 11 Windows 10 More Touch gestures You can use these gestures on the touch screen of your Windows 11 device. Try out these gestures on the touchpad of your Windows 10 laptop. Select an item: Tap on the touchpad. Need more help? Expand your skills. Get new features first. Was this information helpful?
Yes No. Thank you! But what if your application actually needs to support horizontal scrolling? Also, for some applications the default scroll can appear chunky, going too fast or too slow. Experience Optimized for MultitouchThe best-case scenario is when applications are designed from the ground up to support multitouch. This message provides raw touch data to the application, and you can consume these messages and handle multiple touch points. The Windows 7 Multitouch Platform also provides manipulation and inertia processors to help you interpret the touch messages.
Think of manipulation as a black-box that receives as input the object that is being touched and all the related touch messages. The result is a 2D affine transform matrix representing the transformation that happened as a result of the finger movement.
For instance, if you were writing a photo-editing application, you could grab two photos at the same time using however many fingers you wanted to rotate, resize, and translate the photos, and the manipulation process provides the changes you need to reflect on the object. Inertia provides a very basic physics model for applications and provides you with an easy way to continue the smooth transition of an object even after you picked up your fingers from the touch- sensitive device, to create a simple transition effect rather than stopping the object on the spot.
This is the free out-of-the-box behavior, and you will need to opt-out if you wish to stop receiving such messages. Gestures are considered as one or two fingers touch inputs that translate into some kind of predefined action gesture that the user performs. Once detected the OS is doing all the work for you , the OS will send a gesture message to your application. This message contains all the information needed for decoding and making it work. Windows 7 support the following gestures:.
Therefore, in order to determine which gesture you need to handle, first you need to decode the gesture message. The information about gestures is found in the lParam parameter, and you need to use a special function, GetGestureInfo, to decode the gesture message, as shown in the following code snippet.
With this knowledge, we can now move forward and write the complete switch-case method that handles all gestures, as shown in Figure 3. Please note that at the end of the function we call the CloseGestureInfoHandle function that closes resources associated with the gesture information handler.
Failure to do so may result in memory leaks. Handling gesture messages has a fixed flow that includes configuration, decoding the gesture message, and handling the specific gestures according to your application needs. As you can see in the preceding code, it is not that difficult to do so. The zoom gesture allows you to scale the size of your objects.
Figure 4 illustrates how the zoom gesture works. The gesture info-structure includes the dwFlags member that is used to determine the state of the gesture and can include any of the following values:. For zoom gesture, the ptsLocation indicates the center of the zoom. The following zoom message that arrives is handled by the default case.
If in doubt, follow the steps listed below. Alternatively, launch a productivity software such as Paint, select a marker or pencil and swipe three fingers across the screen. If three lines are drawn, then multi-touch has been enabled on your device. Enabling multi-touch is simple and straight-forward.
