问题 My cocoa app calculates the location for every mousedown event. The next time the mouse is clicked, the location is overwritten by the new one. How can I store the locations? Is it possible to create an array with mousedown locations? Thanks 回答1: Sure you can. Since you're dealing with a primitive struct (NSPoint) you'll need to wrap that in an object before you can put it in an NSArray though. NSValue is a ready-made class that allows you to do this, take a look at [NSValue valueWithPoint

问题 So I was spending some time playing around with pure (no external libraries) SVG elements dragging. In general all works, but there is this nasty issue for fast moving mouse: - when user mousedowns a draggable SVG element close to its edge - then drags (mousemove) such draggable too fast - the mouse "loses" the draggable Here the issue is described in more details: http://www.svgopen.org/2005/papers/AdvancedMouseEventModelForSVG-1/index.html#S3.2 Also here the author tried to fix UX by

问题 How do I distinguish whether the event -(void)scrollWheel:(NSEvent *)event was triggered by a Magic Mouse or a trackpad? The reason I'm asking this question is because I want to assign a different action to the scrolling event when a trackpad is used because the user can pinch to zoom on the trackpad. On the magic mouse, however, the user can't pinch easily, so I want to use the scrolling function as a substitute for pinching. I can distinguish between a normal mouse and a Magic Mouse using

问题 What is the most appropriate way of getting the mouse cursor position or button state on Windows (Windows 7 and above)? I previously used DirectInput, but I am not longer using it and do not wish to. I saw there is GetCursorPos, however, I do not see anything for getting mouse button states. I have read previously that just reading the window messages (such as WM_LBUTTONUP) was considered "slow" for real time applications, so I do not know of any other option. 回答1: If you want to poll/query

问题 I got a little Problem with jQuery, maybe you guys can help me. Here's the HTML Markup in jfiddle for better understanding: jsfiddle I'd like to have the div called #move_me to move either to the right or to the left side within the #content_wrapper according to the mouse position inside #content_wrapper . Basically what I want is: if I move my cursor inside the #content_wrapper div to the right then the #move_me div should move to the left to see content2 div, when I move to the left the

问题 I've got a rather large and rather old C application that has been ported to Linux. I'm in charge of getting mouse cursors to work correctly, but having some issues. I was able to convert most of the cursors we require to using the standard cursors provided by XFontCursor by using something like: gCursorTable[waitCurs] = XCreateFontCursor(gDisplay, XC_watch); ... XDefineCursor(gDisplay, WHostWindow(w), gCursorTable[cursor]); XFlush(gDisplay); This is fine for cursors which have analogs in the

问题 I did searches and there were a few similar posts but I can't seem to get it to work. I know that its a cliche but I am quite new to JQuery and JQuery UI as my core skills is PHP, so any help is greatly appreciated. Below are the codes that I have for the JQuery vertical slider. $("#VerticalScrollBar").slider({ orientation: "vertical", change: VerticalHandleChange, slide: VerticalHandleSlide, min: -100, max: 0 }); and the functions function VerticalHandleChange(e, ui) { var maxScroll = $("

问题 I have a JTabbedPane with some tabs and a lot of unused extra space next to the tabs. So I'm trying to use it and place some buttons there (like in Eclipse). I put the buttons on a GlassPane: JPanel glasspane = getPanelWithButtons(); // panel with FlowLayout.RIGHT frame.setGlassPane(glasspane); glasspane.setOpaque(false); glasspane.setVisible(true); This works, and I still can click through on the other elements of my gui (most search results I found are about how to prevent this).
