• WPF graphics, display plot marker (with contact information tooltip) on the mouse event

  Hello

  I need display the coordinates of the point of the field when the mouse pointer is positioned top/close to him.

  I already display a ToolTip with coordinates using the code in this LINK (works equally well for graph).

  However, it is not easy to see where the field is selected, especially when you have more than one land close to eachother.  Is there a way to display some sort of a 'marker '?  A bit of as Signal Analyzer?

  Thank you.

  If you want to display a target and the label next to the value as a user moves the mouse over a graphic, a possibility would be to use SetRelativePosition on a slider.

  If you want to just use a marker in the chart and keep the label in the ToolTip, you can set the relative position of a Visual in the Children collection:

  XAML
  
      
  
          
  
              
  
              ni:Cursor x:Name="cursor" />

            

            Ellipse x:Name="marker" Width="10" Height="10"

                     Stroke="Black" StrokeThickness="2"

                     niPrimitives:RelativePanel.RelativeHorizontalAlignment="Center"

                     niPrimitives:RelativePanel.RelativeVerticalAlignment="Center"

                     />
  
          
  
      

  Code
  
      private void OnPlotAreaMouseMove( object sender, MouseEventArgs e ) {

        IPlot plot = graph.AllPlots[0];

        Point screenPosition = graph.GetPlotAreaPosition( e );

        Point relativePosition = graph.ScreenToRelative( screenPosition );

  // Option 1

        cursor.SetRelativePosition( relativePosition );

  // Option 2

        PlotValue nearestValue = graph.FindNearestValue( plot, relativePosition, query );

        if( nearestValue != null ) {

            graph.ToolTip = string.Format(

                "Nearest value is at ({0},{1}).",

                nearestValue.Value.Cast

  Point nearestValuePosition = nearestValue.GetRelativePosition( );

            RelativePanel.SetRelativeHorizontalPosition( marker, nearestValuePosition.X );

            RelativePanel.SetRelativeVerticalPosition( marker, nearestValuePosition.Y );

        }

• Newbie with the mouse event question

  Hello! I started playing with as3, and I have a function for mouse clicks that draws a shape on each click. However, the mouse click event does not appear to work except when I click on a MovieClip, that I placed in the middle of the screen. Is there a way to make the mouse click event recognize when I click anywhere on the screen?

  Thank you

  Will be

  public void newGame()

  {

  Avatar = new Avatar();                                                  Click the mouse entered only when you click on the avatar?

  addChild (avatar);

  avatar.x = mouseX;

  avatar.y = mouseY;

  addEventListener (MouseEvent.CLICK, clickHandler);

  gameTimer = new Timer (25);

  gameTimer.start ();

  }

  you need to add the event listener to the stage

  stage.addEventListener (MouseEvent.CLICK, clickHandler);

  However you must make sure that this step is not null

  If the code above throws an exception to reference null, you'll also need to add and ADDED_TO_STAGE listener

• Default implementation of the mouse event drag?

  It is a default implementation of the mouse drag event?
  
  Say that if the developer does not override and implement the event drag the mouse, always when you drag the frame, the frame get painted himself in his new role. It indicates a default implementation of the event drag the mouse, but I am unable to know where it has been implemented.
  
  Why bother when everything is working well? I have a requirement to move my modeless dialog box when the frame is moved to another location. I tried to add mousemotionlistener from the frame to the Panel within a framework, but the event does not reach my custom mousedrag event implementation.
  
  Clues?

  Move the frame is a different listener: ComponentListener; Add on to the frame. The frame window decorations are part of the territory of OS, so I don't know if there is a dependency of the system. I think I remember vaguely some systems sending an event that once made the trip, while others send the event as the image moves.

• WPF IntensityGraph, value of the display on the mouse event cell

• Button on the mouse event

  Hello world

  So I've been playing with edge a lot lately, but there's just this thing that I was not able to understand.

  I want a button to shrink in size when someone clicks on it.

  I hosted it in the timeline in the following example: http://www.innua.ca/buttontest

  You see that on mouseover the opacity of the border goes from 20% to 80%, this is done with the following code:

  MouseOver

  sym.getSymbol("butt1").$("butt1_outline").css ("opacity",. 8);

  mouseout/mouseouthandler()

  sym.getSymbol("butt1").$("butt1_outline").css ("opacity",. 2);

  Now, when you click on it, you see the button decrease in size. Works perfectly; only I did manually in the timeline, so that is what I'm looking for the code to do.

  Preferably, I'd like to use transform: scaleX and scaleY and always shrink the key toward the Center.

  Can someone help me with this? Thanks a bunch!

  Here's another solution.

  Action click:

  .CSS ({$(sym.lookupSelector ("Rectangle"))})

  "transform": "scaleX (0.8) (0.8) scaleY", "

  "- ms-transform": "(0.8) scaleX scaleY (0.8)" ", / * IE 9 and 10 * /.

  ' - moz-transform ":" (0.8) scaleX scaleY (0.8) "", / * Firefox * /.

  ' - webkit-transform ":" (0.8) scaleX scaleY (0.8) "", / * Safari and Chrome * /.

  ' "- o - transform": "(0.8) scaleX scaleY (0.8)" "/ * opera * /.

  });

  Well, you can replace $(sym.lookupSelector ("Rectangle")) by $(e.target). This works.

• target the properties of the mouse event: ROLL_OVER, MOUSE: DOWN

  Hi - I'm targeting the States of the button IE: ROLL_OVER is interpolated a bit bigger.

  So I want to go back to its original size.

  BUT it is not recognizing the start and reverse methods.

  Scene 1, Layer "layer 2", 1 environment, Line 60 1061: call to a method maybe not defined in advance through a reference with static type gs:TweenLite.»

  button.addEventListener (MouseEvent.ROLL_OVER, rollOverHandler, false, 0, true);
  button.addEventListener (MouseEvent.MOUSE_DOWN, mouseDownHandler, false, 0, true);
  button.addEventListener (Event.MOUSE_UP, mouseUpHandler);
  button.addEventListener (MouseEvent.ROLL_OUT, rollOutHandler, false, 0, true);

  var myTween:TweenLite = new TweenLite(button,1,{scaleX:1.05,scaleY:1.05,onComplete:myReverseFunction});)

  function rollOverHandler(e:MouseEvent):void

  {

  TweenLite.to (button, 1, {scaleX:1.05, scaleY: 1.05, ease:Elastic.easeOut});})

  myTween.start ();

  }

  function myReverseFunction (): void

  {

  myTween.reverse ();

  }

  There is no such method 'start' to TweenLite, because it starts immediately. If you want to reverse the Tween when it has finished the easiest is to use "yoyo" in TweenMax. (Although you can use onComplete so if you want to).

• How to make the difference between the mouse down events in the control of the chain (click on contour vs click Center)?

  Hello

  I have a control over the chain on my UI and I would like to make the difference between mouse different events, that is to say, to be able to differentiate a click on the outline or the label of the controller vs right-clicking on the Center (between the control in "edit" mode)

  The reason is that sometimes if the user does click not in the Center but in the scope of control, Labview fires the mouse event down but the typed keys are not registered...

  Is it possible to distinguish the two?

  Thanks a lot for your help

  Set the string "update as you type" and use instead a "changed value" event Now, the event fires whenever a new character is entered.

• Event Structure... the mouse down or to the cases of change of value

  I feel, it is a simple problem, but I can't seem to find a solution.

  I have a VI that is supposed to communicate with a stepper motor drive.  I'm working on the Boolean setting keys on the Panel before (acting as of the momentary switches) that will jog the hourly engine or counterclockwise, as long as the button is pressed.  Once the user releases the button, the motor should stop jogging.

  I tried to use the mouse down and value change event.  With the help of the mouse down, for some reason, the time-out occurs almost immediately even while holding the mouse on the button.  This translates into what seems like nothing is happening.  Although the engine receives all orders he has to run, it receives the stop command immediately after.

  Using the value change case, the procedure works and the motor turns, but when you release the button (another change of value), all orders of jog are returned to the engine stop control tracking.  Sometimes the motor continues to run after the shutdown command has been sent, and I think that might be involved because it receives all the shortening of orders (again) and the judgment of control both.

  Is it possible to cnage my case event to run the way I want to what he... Send commands to the button click on... Send different command button.

  Thank you.

  Thanks for the suggestion...

  I could solve the problem I had.  Previously, I was trying to display the timeout to-1 to a value greater than 0 to launch the timeout on a button release event.  To solve the problem, I just removed all of the code that has been changing the value of timeout and left the default to-1.  I also removed all the code in the case of timeout.  Then, I created a new mouse event that is fired by releasing one of the buttons and copied in the code that used to be in the case of timeout.

  Now, the works of VI exactly as I need to... where an event occurs on a mouse a click of a button and a different event happes when the button is released.

  A very simple solution, however I've only worked in BT for about a week and I have not seen the mouse event when I scroll to the event.

• Down on the Image, but not on the mouse scroll bar event?

  Hi all

  I use an event "Mouse Down" on an image to save the coordinates X and Y of the click and increment a counter.  My problem is that I'm looking at an image with a scroll bar that I want to use to set what part of the image is visible.  When I click on the scroll bar, I set off the mouse event down and increments the counter, which I won't do.

  Is there a way to implement a mouse event to the bottom so that it will ignore clicks on the image scroll bars?  If not, can you think of another way to accomplish what I'm doing?

  Thank you!

  Some quick ideas:

  The scroll bars will be a fixed height or width of the right or at the bottom of the indicator. In the mouse to the bottom of the event handler, if the click happens to a set of coordinates that are in a region of scroll bar, you know, do not increment the counter.

  OR

  Maybe you can overlay a transparent image control such that it covers the image but not the scroll bars, and find clicks on this second control.

  Hi all

  I have the obligation to post a selectManyChoice when clicking with the rigth button mouse in a specific area of the page to show/hide the components (in this case panelBox inside a dashboard) instead of having the component (selectManyChoice) visible where it is now, as you can see below:

  Good news, I was able to show wanted.

  Just create the context menu, add showpopupbehavior where I wanted to take the mouse right button, select contextmenu in TriggerType and put the selectManyChoice inside the popup code.

• the transparent parts of component prevents mouse events

  Hello

  I work with a bunch of components that are superimposed on top of eachother.

  Some of the components are odd-shaped and with a transparent background.

  When I try to click on items that are causing others the mouse event is not fireing.

  is there a way I can fix this?

  Drew

  There is a difference between transparent and no background background.  If I take a Sprite and draw a triangle filled like this:

  moveTo (0,0)

  lineTo (100, 100)

  lineTo (100, 0)

  lineTo (0,0)

  Then any component under half, I don't draw is 'visible' mouse and my Sprite get not mouse events.

  If I fill this area with a background with alpha = 0, so I actually placed a piece of glass in my component and it will get the mouse events, even if you can see through things behind him.
