Hide the rectangle of ghost autour last selected item in a listbox

When the user clicks on an item in a control listbox, a ghost (dotted line) rectangle is drawn around the item and it persists even if all items in the listbox are deselected.

How can I make the rectangle of ghosts disappear once it has been created?

VI has begun: no Ghost is visible right now.

The Ghost is present on a selection of a single line:

present on the selection of two lines:

Present when several lines are selected:

Present when no line is selected:

Moreover, it took me a while to understand (by trial and error) for a listbox set to '0 or more elements' selected, how you execute the option to select the element 0 is to click on a single point, then the same point again the control key.  It's just another time I tried that neither planned menu contextual easily accessible "help" Panel objects such as assistance for the stuff on the block diagram.

Here is the excerpt VI used to try...

I spent some time still poking at it and resulted in a solution.

Hide and then redisplay listbox seem to flush out the rectangle.

Shows the attached VI.

And for what it's worth, I enclose a VI and not a preview because the manufacturing process extracts worked as well on the original message. He made a blunder towards the top of the structure of the event and the relations of property of the node with the listbox.  That's what it was supposed to look like at...

  • Determine the index of the selected items in a ListBox?

    Hello

    I can't find a simple/direct method to determine the index of the selected item in a list box.

    I feel I'm missing something, but I can't seem to figure out who (if any) returns an index number if you use it with the recall of .onChange for a ListBox control.

    The following code implements that I need, but is not particularly efficient or elegant and can get confused if you introduce multiple lists to check.

    Any suggestions to reproduce this behavior, even with the best code would be appreciated.

    Thank you!

    var RES = ' palette {text: 'Example-list' properties: {resizable: true}-} ".

    NLP: Panel {orientation: 'row', preferredSize: [400 600]------}

    list1: ListBox {preferredSize: [400 550], properties: {multiselect: true, numberOfColumns:2, showHeaders:true, columnTitles: ["list 1", "item 0"]}}, \

    }}"

    var win = new Window (res)

    Win.Show)

    for (i = 0; i < 10; i ++) {}

    var line = win.pnl.list1.add ("point", "Same entry")

    row.subItems [0] .text = ' paragraph '+ i}.

    Win.PNL.List1.OnChange = function() {}

    var tempArray = new Array()

    for (i = 0; i < win.pnl.list1.items.length; i ++) {}

    If (win.pnl.list1.items [i] .selected == true) {tempArray.push (i)}

    }

    selectedRow = win.pnl.list1.items var [tempArray [0]] .text

    var selectedRowSubitem = win.pnl.list1.items [tempArray [0]] .subItems [0]

    Alert ("selection:" + tempArray + "\n posted content:" + selectedRow + "\t" + selectedRowSubitem)

    }

    .. .in the same time, that should be enough

    win.pnl.list1.onChange = function() {
         alert(this.selection.index); // for this to work set, multiselect:false
    }
    

    I guess you already tried and the result is 'undefined', the reason is that you have this property

    multiselect:true
    

    in this case, the selection returns an array

    this.selection[0].index;
    

    I'd give you the first selected item, even if you only have a single element selected, for all selected items to loop through all the elements in the selection table.

    Thank you myDavey. It's not exactly what I was looking for, but he had good information on something else, I'm trying.

    I found the solution to my problem. This highlighted selection apparently called the object 'key '.

    And it can be used in the script as app.selectionKeyObject. This solves what I was looking for.

    And you can find the last selection by selecting the last item in the selection table.

  • Hide the first and the last Division in the WPF chart axis

    I want to hide the default marker of the first and the last major division in an axis of a chart of WPF. I tried to extend RangeDivisionsMode and define my own class object to the MajorDivisions.Mode property on the axis. But even when I returns a list empty in RangeDivisionsMode.GetDivisions(...), the first and the last marker is drawn.

    Thanks in advance, Jonas

    The minimum and maximum labels are transmitted separately when displaying a scale (even if technical RangeDivisionsMode custom can be used for the minor divisions).

    There is no direct configuration option to hide extreme labels, but you can achieve this effect by initializing the LabelPresenter property on MajorDivisions by a custom implementation:

    class CustomFormatter : GeneralValueFormatter {

            protected override UIElement VisualizeCore( TData value, ValuePresenterArgs args, UIElement existingVisual ) {

                UIElement element = base.VisualizeCore( value, args, existingVisual );

    var axis = (Axis)args.Context;

                Range range = axis.Range;

                var comparer = range.Comparer;

                bool isExtreme =

                       comparer.Compare( range.Minimum, value ) == 0

                    || comparer.Compare( range.Maximum, value ) == 0;

                element.Opacity = isExtreme ? 0.0 : 1.0;

    return element;

            }

        }
