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

Is there a way to display the value of a cell in a popup "as ToolTip' when you click over/hover anywhere on IntensityGraph?

Thank you

Using the technique of the point value of graphic display WPF overview, this is a specific version for intensity data:

private static readonly GraphQueryArgs query = new GraphQueryArgs(
        PlotsToSearch.Any, SearchDimensions.HorizontalAndVertical,
        SearchDirections.ForwardAndReverse, isInclusive: true );

public MainWindow( ) {
        InitializeComponent( );

graph.PlotAreaMouseMove += this.OnPlotAreaMouseMove;
        graph.PlotAreaMouseLeave += delegate { graph.ToolTip = null; };
        ToolTipService.SetInitialShowDelay( graph, 0 );
        ToolTipService.SetShowDuration( graph, int.MaxValue );
    }

private void OnPlotAreaMouseMove( object sender, MouseEventArgs e ) {
        IPlot plot = graph.AllPlots[0];
        Point screenPosition = graph.GetPlotAreaPosition( e );
        Point relativePosition = graph.ScreenToRelative( screenPosition );

PlotValue nearestValue = graph.FindNearestValue( plot, relativePosition, query );
        if( nearestValue != null )
            graph.ToolTip = string.Format(
                "Nearest intensity value is {2} at ({0},{1}).",
                nearestValue.Value.Cast( ).ToArray( ) );
    }

  • 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( ).ToArray( ) );

    Point nearestValuePosition = nearestValue.GetRelativePosition( );

                RelativePanel.SetRelativeHorizontalPosition( marker, nearestValuePosition.X );

                RelativePanel.SetRelativeVerticalPosition( marker, nearestValuePosition.Y );

            }

  • Picture of the events of clusters - change value and the mouse down

    Hello everyone

    I am facing a problem of triggering events using two arrays of clusters.

    I have two paintings of clusters: A and B. There is a Boolean control within each group and to maintain the two paintings in clusters at the same index value (indexVals), the vertical scroll bar of A is hidden but the vertical scroll bar of B is visible. I was using a case with 3 cases triggered by structure: the mouse down, timeout and the mouse upwards. The case of "mouse down" feeds of terminal 1, which makes the case "timeout" the waiting period. The case of "timeout" continues to fuel terminal 1 timeout and has two property nodes (one for A and for B) makes the value of B indexVals is written on the indexVals of a. inside the case of "mouse up" it has a value of-1 for the terminal timeout, putting an end to the process. OK, it was working great. But...

    Now I need to keep the same procedures described above, but I need to raise an event when the user clicks any boolean (led) change state. I thought about the event "change value", but when I click on the led to trigger the event of "change value", the "mouse down" event is also triggered.

    Any suggestions?

    The real VI is a little different from what I described, but the problem is exactly the same.

    Thank you

    Hi all

    When I click in an interactive report I want to resubmit the page with the value of the ID (pk) of the line where I clicked.

    Is this possible with dynamic action (Apex 4)?

    Can someone give me an idea how to do this?

    Kind regards
    Marco

    Hello

    Maybe not easy to do through dynamic measurements (certqainly no ompossible) but much easier the old-fashioned way
    Heres how to do it. Suppose that your primary key column is named ID.

    1 change report IR attributes and change the ID column
    2 scroll down to the section "links"
    3. in etxt link set column, text or Image you prefer.
    4. change the target URL
    5. enter the URL text bix in this

    javascript:apex.submit('#ID#');
    

    Save and run the report.

  • must pass the value on the click event

    I hope I can explain this well. I built a set of miniature furniture which is basically a VBox with an image and text in there field. I have it based on the sample flexstore application. Inside the script of the component, I declare a public variable called model. It contains the name of the corresponding viewstack view. When you click on the thumbnail component I need to update my viewstack with the variable name. I get the variable by calling the event.target.comp between the mouseclick event. The code works fine until I click on the text box or image. Otherwise, he said the model is not defined and there is no default value. How can I make sure that no matter where I click inside the miniature component, it returns this value for me?

    Will put it answered and repost in the appropriate forum. Sorry

  • 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.

    Change it to display the scope and your problem will be solved... or you can store the value in a view or session Variable :)
    for example.

    ADFContext.getCurrent () .getViewScope () .put ('itemName', i); to set the value
    String valueOfi = ADFContext.getCurrent () .getViewScope ().get('itemName').toString; to get the value

    Or via a session scope

    ADFContext.getCurrent () .getSessionScope () .put ('itemName', i); to set the value

  • 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).

  • The point value of graphic display WPF overview

    Hello

    Y at - it an easy way to display the value of a point (with formatting similar to a slider) flying over when the mouse point? I use the chart control WPF (MStudio 2013) with several plots represented graphic on an AxisDouble. (y-axis) and AxisPrecisionDateTime (x axis). Let me know if you need more information and thanks in advance.

    When a Cursor is set to align the data, it uses the FindNearestValue method to find the value of land near. When it is not set to align the data, he reports the value of the current screen with the ScreenToData method. The following code example shows how to use both to display the current value of the mouse on a chart using a ToolTip:

    private static readonly GraphQueryArgs query = new GraphQueryArgs(

            PlotsToSearch.Any, SearchDimensions.HorizontalAndVertical,

            SearchDirections.ForwardAndReverse, isInclusive: true );

    public MainWindow( ) {

            InitializeComponent( );

    graph.PlotAreaMouseMove += this.OnPlotAreaMouseMove;

            graph.PlotAreaMouseLeave += delegate { graph.ToolTip = null; };

            ToolTipService.SetInitialShowDelay( graph, 0 );

            ToolTipService.SetShowDuration( graph, int.MaxValue );

        }

    private void OnPlotAreaMouseMove( object sender, MouseEventArgs e ) {

            IPlot plot = graph.AllPlots[0];

            Point screenPosition = graph.GetPlotAreaPosition( e );

            IList pixelValue = graph.ScreenToData( plot, screenPosition );

            string tip = string.Format(

                "Absolute value at point {0} is {1}.",

                screenPosition, FormatValue( pixelValue ) );

            Point relativePosition = graph.ScreenToRelative( screenPosition );

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

            if( nearestValue != null )

                tip += Environment.NewLine + string.Format(

                    "Nearest value on {0} is {1}.",

                    nearestValue.PlotObserver.Label,

                    FormatValue( nearestValue.Value ) );

    graph.ToolTip = tip;

        }

    private static string FormatValue( IList values ) {

            return string.Join( ", ", values.Cast( ) );
