问题 I'm trying to display the tooltip by calling "ToolTip.Show(String, IWin32Window, Point)", but I wanted to do it like what Windows explorer does - displays the tooltip at the lower left corner of the cursor. I could get the mouse position by "MousePosition", but how could I get its lower left corner position? Thanks, 回答1: If nobody comes up with a better answer you can try this: toolTip1.Show("Am I where you want me to be?", this, this.PointToClient(MousePosition).X, this.PointToClient

问题 I have literally spent all day researching the light out of Unity C# Raycasting and I have nothing to show for it. I have studied tutorials, online resources, stack overflow questions, and have even word for word copied script in hopes that Unity would finally recognize all my attempts to actually use a Raycast. Here is an example of a script using Raycast that simply won't work for me: if (mouseDown) { print ("mouse is down"); Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

问题 Is it possible in MacOS X to send a mouse click to a specific window? I already managed to send a click to the entire screen via CGPostMouseEvent . The windows i want to control overlap each other, so my next idea was to bring the proper window to the front before triggering the click. It works but ends in a total mess... ;-) 回答1: It is possible to send events to Cocoa applications via the undocumented CGEventPostToPSN Here is some code sample from Dave Keck. He posted a little application on

问题 I have been searching for this for a long time, and can't find one single answer. Is it possible to check if my mouse or keyboard is in use (the mouse is currently moving or keys are being pressed) using only a Batch or PowerShell script? If yes, how? 回答1: As for the mouse movement, you could check the position of the pointer and calculate if there is a change over time. $p1 = [System.Windows.Forms.Cursor]::Position Start-Sleep -Seconds 5 # or use a shorter intervall with the -milliseconds

问题 I'm looking for a way to determine if a computer running my game has a trackpad and a mouse connected to it. A typical example would be a laptop with an external mouse connected to it. Is there a Windows API that will return the number of mice/pointing devices connected to the system? I need to support Windows 7+. EDIT I'm keeping the accepted answer because it works and answers my question but I decided not to use it after discovering ManyMouse. It does what I want and allows me to use the

问题 Found a script that uses Excel to move the mouse in VBScript. This is almost exactly what I am looking for for my project, however I need to alter a small bit to enable me to enter coordinates in the code for it to move the mouse specifically to those coordinates; the code currently uses the current mouse position and moves from that position - I need to be able to have the mouse move to an ABSOLUTE position, not a RELATIVE one. Here's the VBS code: Option Explicit Dim Excel, GetMessagePos, x

问题 I am developing a Leap Motion Application where I already move the cursor with it, but I don't know how I can trigger a mouseDown:(NSEvent *) programmatically. 回答1: This worked well for me in Cocoa Mac : void PostMouseEvent(CGMouseButton button, CGEventType type, const CGPoint point) { CGEventRef theEvent = CGEventCreateMouseEvent(NULL, type, point, button); CGEventSetType(theEvent, type); CGEventPost(kCGHIDEventTap, theEvent); CFRelease(theEvent); } Use this link to find out about the
