• How to catch Keyboard and mouse events?

  - by Alexey Malistov

  I want to create an application. This application has to do something when a user presses special keys on keyboard or/and uses scroll wheel. This application is a service. It has no windows. I want to catch any keyboard or mouse events which were designed with other applications. For example, you are watching TV by 3rd party application. If you press Ctrl + Shift and use scroll wheel my application changes the volume. I use Windows 7 x64 and Visual Studio 2008.

• Finding the closest grid coordinate to the mouse onclick with javascript/jQuery

  - by Acorn

  What I'm trying to do is make a grid of invisible coordinates on the page equally spaced. I then want a <div> to be placed at whatever grid coordinate is closest to the pointer when onclick is triggered. Here's the rough idea: I have the tracking of the mouse coordinates and the placing of the <div> worked out fine. What I'm stuck with is how to approach the problem of the grid of coordinates. First of all, should I have all my coordinates in an array which I then compare my onclick coordinate to? Or seeing as my grid coordinates follow a rule, could I do something like finding out which coordinate that is a multiple of whatever my spacing is is closest to the onclick coordinate? And then, where do I start with working out which grid point coordinate is closest? What's the best way of going about it? Thanks!

• Determine which mouse was clicked (multiple mice devices) in .NET

  - by Morten K

  Hi, I want to detect when my touchpad is clicked! I normally use a usb mouse, so I don't use the touchpad for anything. Instead I'd like to make it possible to perform an action in .NET, when the touchpad is clicked. This way I can use it as a shortcut: One tap and something cool happens. Is this possible, and if yes, any clue how? I'd prefer if it could be working in VB.NET or C#. My theory is that I'd have to make a mousehook, which then somehow determines which device the click is coming from. If the click is determined to be from the touchpad, then cancel the click and doWhatever(). Thanks!

• extjs4 display tooltip on button click instead of mouse hover

  - by user856753

  I am trying to add a on click listener to the below tooltip. I do not want the tooltip to display on mouse hover. Instead it need it show on button click. Do I have to add a handler function inside a listener? { xtype: 'button', cls:'my-btn', iconCls:'question', src:'../www/css/slate/btn/question.png', padding: '5 0 0 0', listeners: { render: function(cmp) { Ext.create('Ext.tip.ToolTip', { closable:true, hideDelay : 3000, padding: '0 0 0 0', maxWidth:400, width:800, target: cmp.el, html: "<b>read-only</b>:Users will have read only access to all pages", getTargetXY: function() { return [810, 340]; } }); } } },

• SetCursor reverts after a mouse move

  - by Joe Ludwig

  I am using SetCursor to set the system cursor to my own image. The code looks something like this: // member on some class HCURSOR _cursor; // at init time _cursor = LoadCursorFromFile("somefilename.cur"); // in some function SetCursor(_cursor); When I do this the cursor does change, but on the first mouse move message it changes back to the default system arrow cursor. This is the only code in the project that is setting the cursor. What do I need to do to make the cursor stay the way I set it?

• Telerik RadAjaxManager and Mouse Events in Chrome

  - by kuzco

  Whenever I'm using Telerik's RadAjaxManager in Chrome, the events sent to any mouse events I'm using are passed as null. For instance, the following: <img id="Image1" src="image.gif" onclick="alert(event)" /> <rad:RadAjaxManager ID="RadAjaxManager1" runat="server"> <AjaxSettings> </AjaxSettings> </rad:RadAjaxManager> Alerts null when clicking the image. This does not happen in IE or FF. The version of the RadAjaxManager is 1.8.5.0. I'm guessing the problem does not occur in later versions, but an upgrade is not an option at the moment. I tried Telerik's support forum, but they didn't really provide any answer. What could cause such a problem? And how can it be dealt with?

• overflow-x AND Middle Mouse Button Moving

  - by Rad The Mad

  My Page is 980px in Width, but I have a few design elements (which belong with the background). I positioned them with position: absolute;. This creates a horizontal scrollbar for those who have a =< 1024 resolution. I disabled that scrollbar with overflow-x:hidden on (and for IE7 and etc). However, when I hold my middle mouse button,(i think this applies to laptop touchpads as well) it let's me move around to the right, is it possible to fix this with anything? (javascript, css)? Tested this issues in Chrome, IE, Firefox.

• Screen scraping an application window and interacting with the mouse and keyboard

  - by ccook

  The other day I found myself addicted to a flash game and frustrated by the thing at the same time. In a moment of frustration with the game I thought I would make a 'bot' to beat it for me. Well, I really wouldn't, but it made me realize: I don't know how to interact with another application in a way to do this. Which brings me to the question, how would one take screenshots of another running application and interact with it with the keyboard and mouse. Ideally the solution would be in a managed language like c#. When doing the background reading the net was drowning with articles on scrapping HTML. There were not many articles on actually screen scrapping an application. Diverse answers are appreciated as I’m really looking at surveying what’s out there.

• Generating Mouse-Keyboard combination events in python

  - by freakazo

  I want to be able to do a combination of keypresses and mouseclicks simultaneously, as in for example Control+LeftClick At the moment I am able to do Control and then a left click with the following code: import win32com, win32api, win32con def CopyBox( x, y): time.sleep(.2) wsh = win32com.client.Dispatch("WScript.Shell") wsh.SendKeys("^") win32api.SetCursorPos((x,y)) win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN, x, y, 0, 0) win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP, x, y, 0, 0) What this does is press control on the keyboard, then it clicks. I need it to keep the controll pressed longer and return while it's still pressed to continue running the code. Is there a maybe lower level way of saying press the key and then later in the code tell it to lift up the key such as like what the mouse is doing?

• VS 2010 / Resharper 5 Mouse Behavior

  - by Berryl

  After upgrading to the above configuration I notice that 1) CTRL-Click on a type highlights the type but doesn't take me to the declaration, 2) Clicking on some closure (ie, like a method) toggles whether it's expanded or collapsed. Since these are both mouse related tasks I figure there is some setting in either VS or R# that I need to change, but I sure can't figure out what it is. Anybody know? Cheers, Berryl PS - there is an option in R# to ctrl-click to the type but I have that checked and it still does not work.

• C++ context menu image at left side showing partially, no fully

  - by Samir

  In C++ #define BITMAP_MAIN 201 //in resource.h BITMAP_MAIN BITMAP "main.bmp" // in .rc file // showing icon in menu... HBITMAP imgMain = LoadBitmap( aHinstance, MAKEINTRESOURCE(BITMAP_MAIN) ); SetMenuItemBitmaps ( hSubmenu, uMenuIndex, MF_BYPOSITION, imgMain, imgMain); The problem is in non-English XP OS the main.bmp is showing partially in the context menu. In Vista, Window7 main.bmp is showing just fine. Also in English XP its ok. But why the image is not showing fully in non-English XP? How would I use .ico file here instead of .bmp? This is to make the image transparent.

• Self-expanding Widget, on mouse over

  - by Sergiy Migdalskiy

  I want to implement a widget (with some edit boxes and sliders) that would open beneath or next to a button ("Opener") when I hover it. The key is it's a temporary widget - as soon as it loses focus, I want it gone. Also, I want it to pop up right next to the Opener, ideally pointing an arrow to Opener. So, it's basically a tooltip. But it needs to be a widget with buttons and sliders and stuff like that. Is there a clever way to implement it without making a custom widget and writing handlers for all the mouse and focus events and recomputing its ideal position every time I open it or the Opener moves?

• mouse tracking on IE

  - by Gotys

  Consider the following snippet: $(document).bind('mousemove', function(e) { $('#someDiv').css({left: e.pageX+'px', top: e.pageY+'px'}); }); This should make #someDiv follow the mouse (tooltip), when the css value for "position" is set to absolute. Works as expected, except when you Zoom IN or OUT in IE7 ( dind't try other version of IE). Then the e.pageX gets completely off. The more you zoom in (using your mousewheel + CTRL), the more off the positioning gets. I've tried to break jQuery's UI demos (sliders) and it seems not even jQuery guys have this figured out. Is there any genius out there who knows how to fix this nasty thing? Thanks in advance!

• Adding mouse events to dynamically loaded SWF

  - by Josamoto

  I am loading an external SWF using the Loader class, and adding it to the stage with addChild. When trying to add a mouse click event listener to the MovieClip, using addEventListener, nothing happens, the event never fires. Is there a specific way to add listeners to externally loaded movie clips? My code looks somewhat like this: var target:MovieClip = assets["screensaver"] as MovieClip; target.root.addEventListener(MouseEvent.CLICK, onClickScreenSaver, true); addChild(target); The target shows up on the display, but the CLICK event is completely ignored.

• JQuery: Selecting Text in an Element (akin to highlighting with your mouse)

  - by Jason

  I would like to have users click a link that then selects the html text in another element (NOT an input). By "select" I mean the same way you would select text by dragging your mouse over it. This has been a bear to research because everyone talks about "select" or "highlight" in other terms. Is this possible? My code so far is thus: html: <a href="javascript:" onclick="SelectText('xhtml-code')">Select Code</a> <code id="xhtml-code">Some Code here </code> js (jquery): function SelectText(element) { $("#" + element).select(); } but it doesn't work. Am I missing something blatantly obvious? Thanks

• Gtk_entry mouse click signal

  - by h4rp0

  Hi, I want to do a g_signal_connect to capture a mouse click in a gtk_entry widget. Something like this: entry = gtk_entry_new ( ); gtk_box_pack_end ( GTK_BOX ( hBox ), entry, TRUE, TRUE, 1 ); gtk_widget_show ( entry ); // This is the one I'm not sure about g_signal_connect ( GTK_OBJECT ( entry ), "????????????", GTK_SIGNAL_FUNC ( EntryClicked ), entry ); I just can't seem to find it in the gtk documentation. I've tried using the "focus-in-event", but it is not working as I spect. Thanks for the assistance.

• display alert when mouse hovers over word in text

  - by user1672790

  I have been struggling with this for a few days. I need somebody to steer me in the right direction. I have been searching on the web. I am not sure if I took the right approach. What I need is that each time a person hovers over a particular keyword, it should display an alert box. In this example the word is else. When I run the code it does not give any errors and does not display anything when mouse hovers on the word. function on_func2() { var searchString = 'else'; var elements = document.getElementById('paragraph2'); for (var i = 0; i < elements.length; i++) { if (elements[i].innerHTML.indexOf(searchString) !== -1) { alert('Match'); break; } } }

• Mouse Wheel Scroll - How can I capture the time interval between start and stop of scrolling?

  - by Rahat

  Is there any way to capture the time interval between mouse wheel scroll start and stop? Actually I want to capture the interval between the scrolling start and stop when I very quickly scroll the mouse wheel. I have already looked at MouseWheel event but it don't fulfill my requirement. In senes that it always gives a value of Delta 120 or -120 but i want to call a function depending on the speed of the mouse scroll for example when i scroll the mouse normally i want to perform function 1 and when i scrolled the mouse very quickly i want to perform the function 2. In other words is there any way to distinguish between the mouse scroll high and normal speed. Any advice will be appreciated.

• How do you detect when the mouse leaves the stage in ActionScript 2?

  - by Theo

  I have the bad luck of having to downport some ActionScript 3 code to ActionScript 2 and I have a problem with detecting when the mouse leaves the stage. In ActionScript 3 there is an event called Event.MOUSE_LEAVE, which can be used to detect when the mouse leaves the stage, but there is no equivalent in ActionScript 2 as far as I can see. How would you best emulate the same functionality? Listening for mouse movement and checking the mouse coordinates against the bounds of the stage doesn't work because the mouse coordinates stop updating when the mouse leaves the stage.

• Emacs column editing CUA mode - is it possible to select rectangular region with mouse?

  - by MountainX

  Rectangular or column editing is possible in emacs. And it is very easy with cua-mode enabled. Here are my references for this: Here's a video that shows how to do it: http://vimeo.com/1168225 And see section "CUA rectangle support" here: http://www.cua.dk/cua.html But I also wonder if I can do it with the mouse. I want to select the rectangular region entirely with the mouse (like Scite or Geany can do). Is that possible in emacs?

• How do you get out of "Flash movie keystroke capture" without a mouse?

  - by dan

  When you browse the web with either Chrome or Firefox and you find a Flash movie or TV show player (e.g. on Hulu), the movie will capture a lot of your keyboard input if you activate it somehow. You can still do basic things like ALT+Tab to switch apps, but basically any web browser keyboard shortcut is inaccessible until you use a mouse to click outside the Flash embed. Is there any way to escape the Flash movie without a mouse?

• How to debug lag using Bluetooth connected mouse and A2DP headset?

  - by gertvdijk

  I own a Logitech M555b mouse (since a week) for use with my HP Elitebook 8570w laptop running Kubuntu 12.04. Works fine right after connecting using the KDE Bluetooth control module. However, after some time (seemingly random), it starts to lag. Movements are being delayed for roughly 500ms for a short period of time. Usually it recovers after some time too, but it can take minutes. All actions are being delayed: movements, click, scrolls. Additionally, the movements can be choppy during these times. A workaround that always works for the same short period of time is to disconnect an re-connect the mouse. This can be done using the same KDE Bluetooth control module. What did I try already? Running this at boot time: echo on > `readlink -f /sys/class/bluetooth/hci0`/../../../power/level To disable any power saving features on the Bluetooth hci0 device. Check the mouse's batteries (it's just a week old, other new batteries: same result) Checking logs and kernel messages about Bluetooth-related entries: none aside the expected messages on connect time. I'm running kernel 3.5.0-13-generic as provided in the xorg-edgers PPA. Booting the regular 3.2 Precise kernel results in the same behaviour. Some other information that may help: It happens when no other Bluetooth connections are active on the machine. Similar symptoms also occur on my Bluetooth stereo (A2DP) headset, but then it's audio lagging and skipping. Swapping Bluetooth profiles as described here then helps. Conclusion: it's not the mouse that's faulty. The headset always worked fine using my now dead Thinkpad T61p with built-in Bluetooth. The bluetooth module in my laptop is connected via USB and shows up as Bus 002 Device 003: ID 0a5c:21e1 Broadcom Corp. I'm mobile and several people around me are using Bluetooth at work (A2DP mostly). It also occurs at home, where my neighbours are probably using Bluetooth as well. It could just be radio interference, but I think Bluetooth connections should just hop to another channel. And, moreover, it just works properly instantly when re-connecting. Therefore I think it's a software driver issue and I'd like to debug it. Is there any way to get more verbose logging on the Bluetooth(-hid) modules?
