0 line ListBox and vertical scroll bar problem

Hello

I tried to do simple VI where I can check the items in the Listbox control. My problem is that when I click anywhere on the buttons with the triangles, the mouse down or the vertical scroll bar of the event triggers and check the item in the line 0.

Is this a problem or is it just a mistake in the code?

For some reason, I'm not able to fix VI, so block diagram is below.

Thanks for any help.

I use LV 2010.

Duri

Here's a demo VI, who manages the selection listbox like that with a single click.  Sauve saved in 2011, uses the OpenG table.

  • help with a problem of vertical scroll bar with a list item

    Hello. I have a < s:list > base using an XMLListCollection as there the data provider and a very basic itemrenderer. When a row is clicked in the list a function gets the list.selectedIndex then fills some text with more xml data fields. everything works fine... the problem I have is that the vertical scroll bar on the list seems to be "clickable" - as a line in the list. the scroll bar Scrolls normally but when he clicked on the selectedIndex property becomes-1 which is not useful b/c, the value-1 is passed to the XMLListCollection.

    any ideas? Cheers.

    The default value for SelectedIndex is - 1.  If you have not selected all the items in the list, then it will always return-1.

    Here is a sample application, view, if you select an item and then click the scroll bar is not - 1:

    http://ns.Adobe.com/MXML/2009.
    xmlns:s = "library://ns.adobe.com/flex/spark" >
       
       
            Import spark.events.IndexChangeEvent;
    protected function list1_clickHandler(event:MouseEvent):void {}
    trace ("Click event:", event.currentTarget.selectedIndex);
    }
    protected function list1_changeHandler(event:IndexChangeEvent):void {}
    trace ("change the event:", event.currentTarget.selectedIndex);
    }

  • Problem with vertical scroll bar of the block master detail

    Have a TC of canvas by tabs with 3 tabs - tab A, B and C

    Tab C contains a block of master child multi. Each block can display 5 records.

    C tab

    -> Master Block can display 5 records

    -> Child block can show 5 records. Child block has nearly 20 columns to display. It is therefore a big canvas

    question

    It comes with vertical toolbars on Master Block and child block.

    The horizontal toolbar works very well.

    But if there are more than 5 records, we are not able to scroll the vertical toolbar.

    Remember reading somewhere that for a block of single bar scrolling can be active. Please specify if this is correct and indicate what are the appropriate actions that we can take.

    Thank you

    You have a separate master and detail block, right scroll bar?

    If so, then which bar scroll creating problem for you, master? detail? or both?

    Make sure you have the block with the appropriate scroll bar card, it can possible you have set the bar of scrolling detail with master block and main scroll bar with detail block.

    It is not correct.

    You used the scroll bar with individual block. There is no restriction.

    Hello

    When you tried with your DIV, you specified a width style? I found that it only works when you have this game.

    Something like:

    <div style="overflow-y:scroll; height:100px; width:200px;">
    <pre>
    ...
    </pre>
    </div>
    

    will work, but:

    <div style="overflow-y:scroll; height:100px;">
    <pre>
    ...
    </pre>
    </div>
    

    will not work. I don't know why!

  • Vertical scroll bar table ADF issue when multiple records.

    Hello!

    I use Oracle JDeveloper version 11.1.1.6.0.

    I have a search engine and a simple loan table show only about 1 million records.

    At the top of my search engine, I have navigation buttons (first, previous, next, last).

    So when I click the next button for example, my table will highlight the next line as expected.

    But here's the question. When I click the last button, vertical scroll bar of the table do not scroll (automatically) at the end and show, for me, the last row of table.

    How can I achieve this? When I manually scroll to the last row, I'd find highlighted but I need the vertical scroll bar in response to the last and first buttons click on even though I have a lot of lines.

    What should I do?

    Any suggestion will be highly appreciated

    Life.

    Hi Frank,.

    I found the answer. This is for anyone who ever or encounter the same problem.

    In the table properties Jsf Inspector

    I have linked my table to my java bean (I called it myRichTable).

    I added the first and last buttons as partial of my table triggers

    Java bean

    In my method last() I encluded the following line of code: myRichTable.setDisplayRow (myRichTable.DISPLAY_ROW_LAST).

    And in the first(): myRichTable.setDisplayRow (myRichTable.DISPLAY_ROW_FIRST);

    Thank you!

  • vertical scroll bar in AdvancedDatagrid

    Hi all

    I had an AdvancedDatagid with 100 rows and grouping.

    After the application starts, the vertical scroll bar is not displayed. but after that, to develop a single entry and close it again, the scollbar is illustrated.

    When I force the vertical scroll bar life the command verticalScrollbarPolicy, the scollbar is shown but turned off. Once again, after expand and close one entrance, the scollbar is enabled.

    I guess, the AdvancedDatagid has no idea how many lines are available after reunification. also navigation keys do not work correctly. Up arrow works very well, but isn't the arrow down. But when the scroll bar is correctly displayed, the navigation keys works perfectly.

    After extended and close looks the adg calls that a method and the lines will be calculated. According to this update, ther scrollbar appear correctly.

    someone can tell me, how can I solve this problem?

    In the applicationComplete handler I call the groupCollection.refresh () method and the AdvancedDatagrid.refresh () method.

    Thanks advanced

  • move the vertical scroll bar in a table

    Hello

    In my VI front panel contains a table of results with the visible vertical scroll bar.  When the program runs a performing a test, I am inserting a line every time the captured result.  The row is inserted in the lower part, and when all the visible lines are met you can not see the final result.  What I want to do is either focus on the last row to move the vertical scroll bar or move programmatically control scrollbar itself.  Is this possible?  If this is not the case, what is the property node that I need to display the last line of a table.  I have inserted the data at the top of the table, but this isn't really what the standard application programs do!

  • Vertical scroll bar in the control table

    I use CVI 2012 and using a table control in the editor of the IUR. I started with a table containing 27 rows and 5 columns. The Panel container was large enough to display all the rows and columns, so without scroll bars have been necessary. Then I added more than 14 rows in the table, and a vertical scroll bar appeared on the right edge of the table. «By default, she marched to the bottom of the table, and I tried to change this up by changing"line 41 / 41" to "line 1 / 41" in the editor of the IUR.» He put back the first lines of the table, but the bar scroll also disappeared and I can't seem to restore, even if the table has more lines that can be displayed in the Panel containing.

    In dialog box "Edit Table" editor of the UIR, in the field of the 'appearance of control', the ' scrollbars: ' control has the value ' both scroll bars. I tried a number of combinations in the dialog "Options for size/Scroll...". "so - nothing seems to restore the scroll bar.

    I will attach the UIR file where this is useful. Interest table is the tool 'ID' tab thanks in advance!

    Barry Wealand

    I figured this out. Somehow, the width of the table control had also grown, such as the vertical scroll bar was pushed out the Panel on the right. By adjusting the size of the control so that the width of the table fits once more in Control Panel that contains the scroll bar appears once more.

  • Vertical scroll bar not working not properly on Internet Explorer 11

    The vertical scroll bar does not work on the Favorites menu for example. When you scroll down the Favorites until you can click your choice, it bounces up to the top.

    I have windows 7, IE11 and java. I saw a similar query for vista and the suggestion is to click on "smooth scrolling" in the section advanced options, but this has already been clicked.

    It's very frustrating.

    Something similar is happening under him start / all programs bar vertical, but not as bad.

  • No vertical scroll bar in textarea?

    A vertical scroll bar is not displayed in the textarea tag when the text overflows its vertical size. Is it normal? I tried to use the ' overflow-y: scroll; "and" overflow-y: auto; ' in the .css, nothing helps. It is only a problem in the Playbook browser, and not in FF. What gives? Thank you.

    Exactly... similar problem that happened to me also. So I used the scroll of webkit (I'm able to reproduce letters to display help) for this, but my case is to scroll a page and not to the textarea.
