  • Why do scrollbars stop working when the mouse is too far away?

    - by compie
    Dragging a (Windows) scrollbar only works as long as the cursor is not too far away from the scrollbar itself. How can I 'fix' this bevaviour? Is there some kind of threshold in the registry? Tip: to see this behavior: click on a scrollbar (dont' release the mouse button) and move up/down. This works, as long as you don't move too much to the left.

  • Can I extend my monitors, mouse, keyboard accross a room?

    - by jasondavis
    I am considering building my next PC into a server rack case, the reason is I am getting a server cabinet and will be putting in a few servers in it. It will be in my room where I use my main PC as well and in my case it just makes sense to build my next PC into this cabinet/rack. So my main concern, will I be able to extend my mouse, keyboard, and 2-3 monitors10-15 feet accross a room from my server rack to my desk?

  • Windows 7 boots with a blank screen with mouse cursor only.

    - by user2352
    My Windows 7 machine was powered down without logging out first. Now when booting the PC, Windows 7 does not completely start--instead it boots to an all-black screen with a mouse cursor that can be moved around. There are no icons, toolbars, etc. Ctrl+Alt+Del does not bring up the Task Manager. Booting to Safe Mode renders the same result.

  • How to refactor and improve this XNA mouse input code?

    - by Andrew Price
    Currently I have something like this: public bool IsLeftMouseButtonDown() { return currentMouseState.LeftButton == ButtonState.Pressed && previousMouseSate.LeftButton == ButtonState.Pressed; } public bool IsLeftMouseButtonPressed() { return currentMouseState.LeftButton == ButtonState.Pressed && previousMouseSate.LeftButton == ButtonState.Released; } public bool IsLeftMouseButtonUp() { return currentMouseState.LeftButton == ButtonState.Released && previousMouseSate.LeftButton == ButtonState.Released; } public bool IsLeftMouseButtonReleased() { return currentMouseState.LeftButton == ButtonState.Released && previousMouseSate.LeftButton == ButtonState.Pressed; } This is fine. In fact, I kind of like it. However, I'd hate to have to repeat this same code five times (for right, middle, X1, X2). Is there any way to pass in the button I want to the function so I could have something like this? public bool IsMouseButtonDown(MouseButton button) { return currentMouseState.IsPressed(button) && previousMouseState.IsPressed(button); } public bool IsMouseButtonPressed(MouseButton button) { return currentMouseState.IsPressed(button) && !previousMouseState.IsPressed(button); } public bool IsMouseButtonUp(MouseButton button) { return !currentMouseState.IsPressed(button) && previousMouseState.IsPressed(button); } public bool IsMouseButtonReleased(MouseButton button) { return !currentMouseState.IsPressed(button) && previousMouseState.IsPressed(button); } I suppose I could create some custom enumeration and switch through it in each function, but I'd like to first see if there is a built-in solution or a better way.. Thanks!

  • Improving Click and Drag with C++

    - by Josh
    I'm currently using SFML 2.0 to develop a game in C++. I have a game sprite class that has a click and drag method. The method works, but there is a slight problem. If the mouse moves too fast, the object the user selected can't keep up and is left behind in the spot where the mouse left its bounds. I will share the class definition and the given function implementation. Definition: class codePeg { protected: FloatRect bounds; CircleShape circle; int xPos, yPos, xDiff, yDiff, once; int xBase, yBase; Vector2i mousePos; Vector2f circlePos; public: void init(RenderWindow& Window); void draw(RenderWindow& Window); void drag(RenderWindow& Window); void setPegPosition(int x, int y); void setPegColor(Color pegColor); void mouseOver(RenderWindow& Window); friend int isPegSelected(void); }; Implementation of the "drag" function: void codePeg::drag(RenderWindow& Window) { mousePos = Mouse::getPosition(Window); circlePos = circle.getPosition(); if(Mouse::isButtonPressed(Mouse::Left)) { if(mousePos.x > xPos && mousePos.y > yPos && mousePos.x - bounds.width < xPos && mousePos.y - bounds.height < yPos) { if(once) { xDiff = mousePos.x - circlePos.x; yDiff = mousePos.y - circlePos.y; once = 0; } xPos = mousePos.x - xDiff; yPos = mousePos.y - yDiff; circle.setPosition(xPos, yPos); } } else { once = 1; xPos = xBase; yPos = yBase; xDiff = 0; yDiff = 0; circle.setPosition(xBase, yBase); } Window.draw(circle); } Like I said, the function works, but to me, the code is very ugly and I think it could be improved and could be more efficient. The only thing I can think of as to why the object cannot keep up with the mouse is that there are too many function calls and/or checks. The user does not really have to mouse the mouse "fast" for it to happen, I would say at an average pace the object is left behind. How can I improve the code so that the object remains with the mouse when it is selected? Any help improving this code or giving advice is greatly appreciated.

  • GAME MAKER Problem with sprites! Can't see the sprite after mouse action

    - by user46882
    I have got a problem in Game Maker Pro: http://www.directupload.net/file/d/3646/egdpdu6u_gif.htm At the start we see a white square moving. If I press a key the square stop to move and the background changes to white. If the background changes to white a new animation/sprite should play on the same position where the white square was. BUT IT DOESNT! (Actually it is still there! It just does not move and this is fine) The animation is basically a sprite animation with some outlines of the square. If I press a key again, the background changes to white and we see the animation of the sprite.. but we do not see the animation of the sprites when it does not move. And this is strange!! I want to have the animation of the square when it doesn't move. But I don't get it.. by the way.. the .gif is a old version. I allready fixed the problem with the moving animation.. but I am still not able to play the animation if the square does not fly. The color of the animation is allready set to green or something! for better contrast. But still.. can't see it. Here is the code: obj.weisse.kugel.stepevent = the white square with the movements and sprite animations etc. if (global.kweiss == 1 ) { // vspeed = 8; //visible = true // sprite_index=spr_weisse_kugel; image_speed = 0; image_index = 0; } else if (global.kweiss == 0) { sprite_index=spr_animation_fade_out; image_speed =0.2; image_index=image_number-1 vspeed = 0; //visible = false // } then I have 1 create event for all the global.variables obj.global_var globalvar kweiss; kweiss = 1; globalvar kschwarz; kschwarz = 0; and then I have 1 controll stepevent in a new obj: if device_mouse_check_button_pressed (0, mb_left) { if background_color = c_black { background_color = c_white } else { background_color = c_black } // change of the square to white if (global.kweiss = 0) { global.kweiss = 1; } else { global.kweiss = 0; } if (global.kschwarz = 0) // change the square to black (other bullets.. we do not need this at the moment!) { global.kschwarz = 1; } else { global.kschwarz = 0; } Many thanks in advance

  • 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?

  • CSS: Freeze table header and first column, *but only on certain axes*

    - by Mega Matt
    Hello all, I have a variation on a common question, and I'll try to explain it as best I can. It may take some visualization on your part. I have an HTML table (in reality there are tables within tables within divs within tables -- I'm using the JSGantt plugin). I'd like for the table header to be frozen only when I scroll down on the y-axis, but if I need to scroll right to see more data, I would like it to scroll right. Meanwhile, as I scroll down (with the header row staying put), I'd like the first column of the table to scroll down with me. But when I scroll right, I want the first column to stay put (but as I mentioned above, the header row to scroll with me). So essentially I've frozen the first column only on the x-axis and the header row only on the y-axis. I'll stop there for now. If anyone needs more clarification I can try to explain. I've tried this multiple ways, but I'm convinced that it may not be possible without some serious javascript. The table, by the way, is contained within an outer div with set dimensions, hence the need for me to scroll the data. Any help you can provide would be greatly appeciated. Thanks very much.

  • Any way to disable horizontal scroll for FlowLayoutPanel in AutoScroll mode?

    - by P a u l
    I need a System.Windows.Forms.FlowLayoutPanel that only auto scrolls vertically. WrapContents is false, and I want it to work like a vertical stack panel. I can't find a way to disable the horizontal scroll. I've googled it, can't find a usable solution so far. The alternative is to abandon the FlowLayoutPanel, and try another control. What acts somewhat like a WPF stack panel but that expands and shrinks vertically with the contained controls?

  • How do you make a CSS-defined table-cell scroll?

    - by Giffyguy
    I want to be able to set the height of the table, and force the cells to scroll individually if they are larger than the table. Consider the following code: (see it in action here) <div style="display: table; position: absolute; width: 25%; height: 80%; min-height: 80%; max-height: 80%; left: 0%; top: 10%; right: 75%; bottom: 10%; border: solid 1px black;"> <div style="display: table-row;"> <div style="display: table-cell; border: solid 1px blue;"> {Some dynamic text content}<br/> This cell should shrink to fit it's contents. </div> </div> <div style="display: table-row;"> <div style="display: table-cell; border: solid 1px red; overflow: scroll;"> This should only take up the remainder of the table's vertical space. This should only take up the remainder of the table's vertical space. This should only take up the remainder of the table's vertical space. This should only take up the remainder of the table's vertical space. This should only take up the remainder of the table's vertical space. This should only take up the remainder of the table's vertical space. This should only take up the remainder of the table's vertical space. This should only take up the remainder of the table's vertical space. </div> </div> </div> If you open this code (in IE8, in my case) you'll notice that the second cell fits in the table nicely when the browser is maximized. In theory, when you shrink the browser (forcing the table to shrink as well), a vertical scrollbar should appear INSIDE the second cell when the table becomes too small to fit all of the content. But in reality, the table just grows vertically, beyond the bounds set by the CSS height attribute(s). Hopefully I've explained this scenario adequately... Does anyone know how I can get this to work?

  • How can I get a custom UITableView to automatically scroll to a selected text field?

    - by nornagon
    I have a UITableView, which I am controlling from a custom UIViewController. When the user clicks the 'add' button, I add a row to the UITableView with a text field in it, and make it the first responder. The problem is, when the bottom of the table is out of view (or hidden by the keyboard), the UITableView doesn't scroll to bring the text field into view. UITableViewController does this automatically, but my View Controller can't be a subclass of UITableViewController.

  • Scroll event of jquery is not working in IE 7 with IE 7 standard but works in IE8,9

    I have an example below which has a terms div which has some terms and conditions as content. When the user scroll the div to bottom, then the checkbox is enabled.
