mouseevent

问题 i have a table row and i want to have two functions when i click onto this. With a long-press i want to select the row (add an ".active_row" class) and with a normal click i want to open the details site for this dataset. For the long-press detection i use the third party script found here. With little modifications it works for me and fires the event "long-press" correctly. But the problem now ist, if i release the mousebutton the events mouseup and click are fired too... i compared the

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 21 days ago . I am currently in my first year of Java and have stumbled upon this code on the internet about a battleship game. What I would like to do is understand this code in more simple code. The part that confuses me is the first line: "computerGameBoard = new GameBoard(true, event ->". I

问题 In a QWidget derived class object with implemented tabletEvent(QTabletEvent *event) and mousePressEvent(QMouseEvent *event), the mousePressEvent gets called every time tabletEvent gets called with type TabletEvent::TabletPress. According to the Qt documentation, this should not happen: The event handler QWidget::tabletEvent() receives TabletPress, TabletRelease and TabletMove events. Qt will first send a tablet event, then if it is not accepted by any widget, it will send a mouse event .

问题 This question already has an answer here : What does “possible lossy conversion” mean and how do I fix it? (1 answer) Closed 2 years ago .

问题 I'm trying to access the variable myvar from outside like so: $(document).mousemove(function(e){ var myvar = winHeight() + scrollY() - e.pageY; }); console.log(myvar); But Chrome's javascript console keeps saying "Uncaught ReferenceError: myvar is not defined all-products:203 (anonymous function)" What am I doing wrong? How do I access this variable outside this function? EDIT: I've realised that what I was attempting to do isn't realisable. I have since changed my strategy completely and the

问题 I need to retrieve the index of the caret inside a textbox in the focused window, maybe using UI Automation, or maybe a Win32 API function, if there's any function that cat do that. And I emphasize, I don't mean the x,y coordinates, but the index of the caret inside the text of the textbox. How can I do that? Also see this similar question. 回答1: You can use UI Automation for that, and especially the IUIAutomationTextPattern2 interface that has a GetCaretRange method. Here is a sample

问题 I want to use Robot to click mouse button 4, side button. The InputEvent only have the 3 standard left, middle (scroll) and right buttons. InputEvent.BUTTON1_DOWN_MASK = 1024 InputEvent.BUTTON2_DOWN_MASK = 2048 InputEvent.BUTTON3_DOWN_MASK = 4096 So I tried to flow the formula and send to the Robot the number 8192 public static void main(String[] args) { try { Robot mouseHandler = new Robot(); mouseHandler.mousePress(8192); mouseHandler.mouseRelease(8192); } catch (AWTException e) { e

问题 I am using the following code to get mouse messages on the current process. using (Process curProcess = Process.GetCurrentProcess()) using (ProcessModule curModule = curProcess.MainModule) { return SetWindowsHookEx(WH_MOUSE_LL, proc, GetModuleHandle(curModule.ModuleName), 0); } For some reason when this code runs the mouse get slow for several seconds and then back to normal. Any ideas? Thanks EDIT - hook method private static IntPtr mouseEvent(int nCode, IntPtr wParam, IntPtr lParam) { if
