  • How do I disable window move with alt + left mouse button in GNOME Shell?

    - by artfulrobot
    There are lots of posts on this about Unity, this is about gnome-shell As with other posters, I use apps (Inkscape in particular) that uses Alt-Click and Alt-drag. Gnome-shell is grabbing this off me and thus disabling features in the application. I have tried using ccsm's Move plugin - you can turn this off and you still get Alt-drag window moving. using gconf editor to change /apps/metacity/general/mouse_button_modifier - this has no effect AFAICS. It's really hindering me. Otherwise I find gnome-shell a really productive environment.

  • Why does the HUD jump around as I type or move my mouse?

    - by Ryan McClure
    I use the Unity Revamped package for my Unity interface. I have noticed that, however, this behavior exists for any account on my computer, even guest, on BOTH the Revamped and the Canonical release of Unity. Here is a link to what it looks like, because it is hard to describe it. I don't know of anyone else who has this issue. I am running Unity 5.16 on Ubuntu 12.04. As an aside, I also have noticed this behavior with a fresh install of 12.10 Beta 1 on a separate partition.

  • What's the best way to structure this Linq-to-Events Drag & Drop code?

    - by Rob Fonseca-Ensor
    I am trying to handle a drag & drop interaction, which involves mouse down, mouse move, and mouse up. Here is a simplified repro of my solution that: on mouse down, creates an ellipse and adds it to a canvas on mouse move, repositions the ellipse to follow the mouse on mouse up, changes the colour of the canvas so that it's obvious which one you're dragging. var mouseDown = Observable.FromEvent<MouseButtonEventArgs>(canvas, "MouseLeftButtonDown"); var mouseUp = Observable.FromEvent<MouseButtonEventArgs>(canvas, "MouseLeftButtonUp"); var mouseMove = Observable.FromEvent<MouseEventArgs>(canvas, "MouseMove"); Ellipse ellipse = null; var q = from start in mouseDown.Do(x => { // handle mousedown by creating a red ellipse, // adding it to the canvas at the right position ellipse = new Ellipse() { Width = 10, Height = 10, Fill = Brushes.Red }; Point position = x.EventArgs.GetPosition(canvas); Canvas.SetLeft(ellipse, position.X); Canvas.SetTop(ellipse, position.Y); canvas.Children.Add(ellipse); }) from delta in mouseMove.Until(mouseUp.Do(x => { // handle mouse up by making the ellipse green ellipse.Fill = Brushes.Green; })) select delta; q.Subscribe(x => { // handle mouse move by repositioning ellipse Point position = x.EventArgs.GetPosition(canvas); Canvas.SetLeft(ellipse, position.X); Canvas.SetTop(ellipse, position.Y); }); the XAML is simply <Canvas x:Name="canvas"/> There's a few things I don't like about this code, and I need help refactoring it :) First of all: the mousedown and mouseup callbacks are specified as side effects. If two subscriptions are made to q, they will happen twice. Second, the mouseup callback is specified before the mousemove callback. This makes it a bit hard to read. Thirdly, the reference to the ellipse seems to be in a silly place. If there's two subscriptions, that variable reference will get overwritten quite quickly. I'm sure that there should be some way we can leverage the let keyword to introduce a variable to the linq expression that will mean the correct ellipse reference is available to both the mouse move and mouse up handlers How would you write this code?

  • How do I pan the contents of a div when the right mouse button is dragged?

    - by Shaunwithanau
    I need a cross browser way of capturing the right mouse click, preventing the default context menu and making it where when the user drags the mouse they can pan the contents of a div. This is largely similar to Google maps in that they will grip the contents and drag to see what they want. No external libraries please. I am already capturing the events, and know that this will prevent default actions: if (evt.preventDefault) { evt.preventDefault(); } else { evt.returnValue = false; } But this doesn't prevent the context menu AFAIK. Edit: I really am unsure about how to prevent the context menu and what the best way to manipulate the scroll bars would be? examples would be great

  • Linux, how to capture screen, and simulate mouse movements.

    - by 2di
    Hi All I need to capture screen (as print screen) in the way so I can access pixel color data, to do some image recognition, after that I will need to generate mouse events on the screen such as left click, drag and drop (moving mouse while button is pressed, and then release it). Once its done, image will be deleted. Note: I need to capture whole screen everything that user can see, and I need to simulate clicks outside window of my program (if it makes any difference) Spec: Linux ubuntu Language: C++ Performance is not very important,"print screen" function will be executed once every ~10 sec. Duration of the process can be up to 24 hours so method needs to be stable and memory leaks free (as usuall :) I was able to do in windows with win GDI and some windows events, but I'ev no idea how to do it in Linux. Thanks a lot

  • Making a JQuery tooltip retrieve a new value every time the mouse moves.

    - by Micheal Smith
    As i am developing an application that makes use of a tooltip that will display a different value when the user moves the mouse. The user mouses over a table cell and the application then generates a number, the further right the cursor moves in the cell, the higher the value increases. I have created a tooltip that runs and when the cursor mouses over the cell, it does indeed show the correct value. But, when the i move the mouse, it does not show the new value but just the older one. I need to know how to make it update everytime the mouse moves or the value of a variable changes, Any ideas for the problem? <table> <tr id="mon_Section"> <td id="day_Title">Monday</td> <td id="mon_Row"></td> </tr> </table> Below is the document.ready function that calls my function: $(document).ready(function() { $("#mon_Row").mousemove(calculate_Time); }); Below is the function: <script type="text/javascript"> var mon_Pos = 0; var hour = 0; var minute = 0; var orig = 0; var myxpos = 0; function calculate_Time (event) { myxpos = event.pageX; myxpos = myxpos-194; if(myxpos<60) { orig = myxpos; $('#mon_Row').attr("title", orig); } if (myxpos>=60 && myxpos<120) { orig=myxpos; $('#mon_Row').attr("title", orig); } if (myxpos>=120 && myxpos<180) { orig=myxpos; $('#mon_Row').attr("title", orig); Inside the function is the code to generate the tooltip: $('#mon_Row').each(function() { $(this).qtip( { content: { text: false }, position: 'topRight', hide: { fixed: true // Make it fixed so it can be hovered over }, style: { padding: '5px 15px', // Give it some extra padding name: 'dark' // And style it with the preset dark theme } }); }); I know that a new value is being assigned to the cells title attribute because it will display inside the standard small tooltip that a browser will display. The JQuery tooltip will not grab the new value and display it, only the variables initial value when it was called.

  • WPF: how to make normal listbox left-drag-select behavior use middle mouse instead?

    - by Scott Bilas
    I'm building a special listbox control that our designers want customized in some tweaky ways. One thing they want to see is that the middle button-drag does what the left button-drag normally does (we are repurposing left-drag to other things). So it needs the two key features that left-drag does in a ListBox default implementation: While holding down the button and dragging, the selection starts where I click down and extends to where I drag. While dragging outside the listbox region, it scrolls if there is scrollable space in that direction. Before I go an duplicate this functionality by hand, is there any easy way to fool ListBox into thinking it's getting left-mouse drag events but instead is getting middle-mouse?

  • jQuery animate slidding background image using mouse position wont stop... just keeps going

    - by simian
    I have a neat little jQuery script I am working on. Goal: parent div with overflow hidden holds a larger div with image. When I move the mouse to the left or right of the parent div, the div with image changes margin-left to move left or right. Problem is... if I move the mouse out of the parent div (left or right), the image keeps going. I need the image to stop when the mouse is not on the inside left or right edge of the parent div. Any ideas? <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript"> //<![CDATA[ jQuery.noConflict (); jQuery(document).ready(function(){ jQuery('#container').mousemove(function(e){ var parentWidth = jQuery('#container').width(); var parentWidthLeft = Math.round(.1 * jQuery('#container').width()); var parentWidthRight = Math.round(jQuery('#container').width() - parentWidthLeft); var parentHeight = jQuery('#container').height(); var parentOffset = jQuery('#container').offset(); var X = Math.round(e.pageX - parentOffset.left); var Y = Math.round(e.pageY - parentOffset.top); if (X<parentWidthLeft) { jQuery('#image').animate({'left': '-' + parentWidth }, 5000); } if (X>parentWidthRight) { jQuery('#image').animate({'left': parentWidth }, 5000); } if (X<=parentWidthRight && X>=parentWidthLeft) { jQuery('#image').stop(); } if (X<1) { jQuery('#image').stop(); } }); jQuery('#container').mouseleave(function(){ jQuery('#image').stop(); }); }); // ]]> </script> </head> <body> <div id="container" style="width: 500px; height: 500px; overflow: hidden; border: 10px solid #000; position: relative; margin: auto auto;"> <div id="image" style="position: absolute; left: 0; top: 0;"><img src="http://dump4free.com/imgdump/1/Carmen-Electra_1wallpaper1024x768.jpg" alt="" /></div> </div> </body> </html>

  • How can I observe the style on an element during mouse-over?

    - by DaveDev
    We supply micro-site content to a client. They supply us with a HTML wrapper and we inject our content into it. I'm trying to debug an issue where our style sheet appears to be interfering with the style in their wrapper. Normally I'd use firebug or IE Developer Toolbar to select the element and I can see which styles are being applied, which are being overridden and where they are coming from. But this particular problem only exists when I hover the mouse over a link. Specifically, the link shrinks a little bit. Is there anything that I can use to see what the browser is doing with the styles when I hover the mouse over the link?

  • How can I stop Flash from leaving full-screen mode when it loses focus due to a mouse-click in the o

    - by therefromhere
    On a multi-monitor system, if I'm viewing a full-screen video in Flash on one monitor, clicking the mouse on the other monitor causes Flash to leave full-screen mode and revert to normal size. What's the easiest way of preventing this that works on my version of Flash? My system is Flash 10 (10.0.12.36), in Firefox 3.5 on Windows Vista 64, but I think it affects all current versions. This is very annoying behaviour, but unfortunately, according to this bug report response it seem to be a security feature, rather than a bug: We understand that many users would like fullscreen on one monitor and to be able to interact with your OS on another monitor. However, due to security requirements, we require that Flash and Browser must be the current focus of your OS.

  • Openoffice.org: Mouse wheel one row at a time possible?

    - by Maksee
    I noticed this in Excel, now in OpenOffice.org calc. One small change in mouse wheel leads to 3 rows (line) change. Is it possible to change in Calc OR/AND in Excel? EDIT: Yes, I know about system wide setting about the number of lines for one notch of scroll. But in some applications this setting is interpreted related to size in pixels so scrolling is predictable, but for some like spreadsheet is not. Since the height of line in a cell differ depending of the cell content, with other setting as 1 you will have a guarantee of unpredictable content before your eyes with only one notch.

  • table cell background color change problem

    - by Mellon
    I work on another guy's code, and I try to change the table cell background color when mouse over the cell, and change back to the original background color when mouse leave. I use the following code: var bgcolor=$(".cell-el").css("background-color") $(".cell-el").hover( function(){ $(this).css("background-color", "#3c3c36")}, //mouse enter, bg-color change function(){ $(this).css("background-color", bgcolor) // mouse leave, bg-color change back }) Things are working fine, EXCEPT that when mouse first time enter the cell, the cell background color is not changed to "#3c3c36", but when mouse leave the cell after first entering and enter in the cell again, the cell's background color changed to "#3c3c36". That's the cell color never change for mouse first enter, after that, everything is working great. What's could be the cause of this problem?

  • Implementing zoom on a fixed point, javascript/canvas

    I want to implement zooming on the mouse pointer with the mouse wheel. That is scaling the image while the point under the mouse pointer stays fixed. Here is my code, which doesn't work very well var scala = 1 + event.wheelDelta / 1000; canvas.context.translate(-canvas.mouse.x * ( scala - 1 ) / canvas.scale,-canvas.mouse.y * ( scala - 1 ) / canvas.scale); canvas.context.scale(scala,scala); canvas.scale *= scala; //canvas.scale is my variable that is initially set to 1. //canvas.mouse is my variable that represents the mouse position relative to the canvas

  • How can i get my KVM switch to work? (win7 & ubuntu 10.10)

    - by Will W.
    i bought a KVM switch and i'm trying to use it to have it connected to my main PC (win7) and my new machine i just installed ubuntu on. I hooked it up properly, and tried using it. It worked when switching from the win7 machine to the ubuntu one, but after the (1st and only) successful switch, ubuntu just didn't seem to recognize my mouse or keyboard. Basically when i tried it the easiest was to explain what happened was it only worked with Win7. When i switched over to ubuntu by doing a [scroll-lock] [scroll-lock], my keyboard and mouse were not recognized. However, the lights on the keyboard and mouse did work when on ubuntu, but they didn't function, and since keyboard wouldn't function, i couldn't do a [scroll-lock] [scroll-lock] to switch back to the win7 machine. So i was basically locked in to ubuntu with no mouse or keyboard, and i had to unplug the keyboard/mouse usb's and d-sub to plug the monitor d-sub back into win7 computer to type up this thread and google the issue. Seems some people have had this issue before but i couldn't find a fix... I am 80% sure it has to do with drivers... but there isn't any for KVM switches, at least not this one also i never was unable to find ubuntu drivers/firmware for my mouse and keyboard (Logitech G15 and Razer Deathadder 3500). I don't know how to fix this, perhaps someone super-savvy could write/code a script or work-around or something? I really need to get this thing working, my back is getting sore from bending over and plugging in / unplugging usb/monitor/usb/monitor/usb/usb over and over again lol... and i really would be sad if the constant plugging unplugging of the usb's or the d-sub port would over time damage the ports... i don't want that... There has to be some way to get this working.. Can anyone help? The KVM is a IOGEAR GCS632U Win7 x64 Ubuntu 10.10

  • Command Pattern refactor for input processing?

    - by Casey
    According to Game Coding Complete 4th. ed. processing input via the following is considered unmanagable and inflexible. But does not show an example. I've used the Command pattern to represent GUI button commands but could not figure out how to represent the input from the keyboard and/or mouse. if(g_keyboard->KeyDown(KEY_ESC)) { quit = true; return; } //Processing if(g_keyboard->KeyDown(KEY_T)) { g_show_test_gateway = !g_show_test_gateway; } if(g_mouse->ButtonDown(a2de::Mouse::BUTTON2)) { g_selected_part = GWPart::PART_NONE; SetMouseImageToPartImage(); } ResetButtonStates(); g_prevButton = g_curButton; g_curButton = GetButtonHovered(); if(g_curButton) { g_mouse->SetImageToDefault(); if(g_mouse->ButtonDown(a2de::Mouse::BUTTON1) || g_mouse->ButtonPress(a2de::Mouse::BUTTON1)) { ButtonPressCommand curCommand(g_curButton); curCommand.Execute(); } else if(g_mouse->ButtonUp(a2de::Mouse::BUTTON1)) { if(g_prevButton == g_curButton) { ButtonReleaseCommand curCommand(g_curButton); curCommand.Execute(); if(g_curButton->GetType() == "export") { ExportCommand curCommand(g_curButton, *g_gateway); curCommand.Execute(); } } else { ResetButtonStates(); } } else { ButtonHoverCommand curCommand(g_curButton); curCommand.Execute(); } } else { g_status_message.clear(); SetMouseImageToPartImage(); if(g_mouse->ButtonDown(a2de::Mouse::BUTTON1)) { CreatePartCommand curCommand(*g_gateway, g_selected_part, a2de::Vector2D(g_mouse->GetX(), g_mouse->GetY())); curCommand.Execute(); } }

  • How to use keyword this in a mouse wrapper in right context in Javascript?

    - by MartyIX
    Hi, I'm trying to write a simple wrapper for mouse behaviour. This is my current code: function MouseWrapper() { this.mouseDown = 0; this.OnMouseDownEvent = null; this.OnMouseUpEvent = null; document.body.onmousedown = this.OnMouseDown; document.body.onmouseup = this.OnMouseUp; } MouseWrapper.prototype.Subscribe = function (eventName, fn) { // Subscribe a function to the event if (eventName == 'MouseDown') { this.OnMouseDownEvent = fn; } else if (eventName == 'MouseUp') { this.OnMouseUpEvent = fn; } else { alert('Subscribe: Unknown event.'); } } MouseWrapper.prototype.OnMouseDown = function () { this.mouseDown = 1; // Fire event $.dump(this.OnMouseDownEvent); if (this.OnMouseDownEvent != null) { alert('test'); this.OnMouseDownEvent(); } } MouseWrapper.prototype.OnMouseUp = function () { this.mouseDown = 0; // Fire event if (this.OnMouseUpEvent != null) { this.OnMouseUpEvent(); } } From what I gathered it seems that in MouseWrapper.prototype.OnMouseUp and MouseWrapper.prototype.OnMouseDown the keyword "this" doesn't mean current instance of MouseWrapper but something else. And it makes sense that it doesn't point to my instance but how to solve the problem? I want to solve the problem properly I don't want to use something dirty. My thinking: * use a singleton pattern (mouse is only one after all) * pass somehow my instance to OnMouseDown/Up - how? Thank you for help!

  • Maintaining Mouse Control in Embedded swfs (i.e. parent / child ) Flash cs4 AS3

    - by garydev
    Hello to all, I have an issue that is driving me nuts. I have an AS3 application that performs a calculation based upon user's input to determine a result. The purpose is to predict the results of a horse's coat color based on the genetics. The results are given in a 3d model swfs that are loaded into the "shell's" UILoader Component and they rotate. I have an example of this here: http://www.provideoshow.com/coatcalculator/coat_calculator.html As you can see this works fine with an "auto-rotate" feature. The problem is that my client wants the 3d models to be rotated by the user's mouse. I have the 3d models rotating with the mouse but they only work when they are stand alone swfs. They break when they are loaded into the shell. Some research informs me that the issue is in the stage properties and the parent not receiving them from the child. I've gotten some advice that I need to pass a reference to the shell's stage and preferably in the init function. This is the code I have in the child which is loaded as a class public function Main_master_withmouse() { if(stage) { _stage = stage; init(stage); } } protected function init(rootStage:Stage):void { if(rootStage) { _stage = rootStage; } else { _stage = this.stage; } sceneWidth = _stage.stageWidth createChildren(); startRendering(); } I can't figure out what to put in the parent to pass the reference to its stage. Any help is greatly appreciated. Thank you in advance
