touch

问题 I have already seen fingurePaint.java from API demos.

It is working to erase something which is drawn by touch. public class SandboxView extends View implements OnTouchListener { public final Bitmap bitmap; private final int width; private final int

问题 I'm trying to have the advantage of the UITextView with Data Detector Types inside a TableViewCell that is itself clickable. The only thing is, I need the UITextView's links to be clickable, so userInteractionEnabled = YES, unfortunately this will prevent any touch going through to the UITableViewCell. Of course the UITextView can't be edited, I also subclassed it refusing it to be first responder to avoid selecting text in it. The only thing I need, is detecting that if a user touch the

问题 I use the unix command 'touch' a lot to update time-stamps of any new acquired/downloaded file in my system. Many a times the time-stamp of the existing file is old so it can get lost in the system. Is there a way in MS-Windows powershell to do so. I have both powershell 5 as well as powershell 6. 回答1: You can use $file = Get-Item C:\Intel\Logs\IntelCpHDCPSvc.log $file.LastWriteTime = (Get-Date) Or CreationTime or LastAcccessTime, if you prefer. As a function Function

问题 I use the following code to detect whether the device is a touch device or not: var isTouchDevice = 'ontouchstart' in window || navigator.msMaxTouchPoints; if(isTouchDevice) { $('body').addClass('yes-touch'); } else { $('body').addClass('no-touch'); } I use this to only show :hover states when it is NOT a touch device (as most touch devices interpret a tap as a hover). .no-touch .element:hover { color: red; } The problem is, one of our PCs in the office is an all-on-one touch screen PC, which

问题 I use a touchscreen device detection like this: if (window.navigator.maxTouchPoints || 'ontouchstart' in document) // handle as mobile device else // handle as desktop When I change the screen in Chrome mobile emulation the result of both maxTouchPoints and 'ontouchstart' in document is unpredictable. For one and same emulated screen it may return maxTouchPoints equals to 0 or 1, and 'ontouchstart' in document equals to true or false . So, I cannot really on this check. Could you recommend a
