Vertical scroll bar position change list

Hi all

Selection of the list makes the list (scroll) jump to move the selected entry to the top any idea on this issue.

Kind regards

Try it in a simple test case. I don't think that's the default behavior.

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:

Just checked in my application (11.1.2.3, 1000 + lines) and it works as expected.
You can try to reproduce this problem with simple test cases and if it works then compare table and properties of VO.

long pull down the menu with no vertical scroll bar

People,

It's been 3.5 years ago when we had to learn that there is no way to have a long drop down menu control without a vertical scroll bar. See

http://forums.NI.com/NI/board/message?board.ID=170&message.ID=217428&query.ID=395029#M217428

Now, after that we got LabVIEW 8.6.1 there is still no the ability to remove the vertical scroll bar if there is a 'Vertical Scrollbar Visible' property node for the drop-down list boxes. As already observed in 2006 with the drop-down list 8.2 LV Smercurio, this property node has no effect, probably because of a bug. This behavior is always the same with LV 8.6.1.

A few days ago a user of our software have complained that the menu items would be missing. In fact, they were not, but rather he oversaw the scroll bar and do not scroll to the bottom of the column - that's why it did not find the menu items. In general, it's pretty annoying if you have to scroll first before you can select a particular item. In most cases, the scroll bar is all just useless since the Panel is large enough to display all menu items at the same time.

How do you design a long drop-down menu on your UI? Any ideas how to get around the scroll bar mean?

Sorry for the lengthy post. I'm afraid that you have to use the vertical scroll bar while reading my text...

Thanks for any input,

Peter

I think that's what you're asking. This works for any named digital control, and I think a small change will be too much work for a drop-down list box.

Move the vertical scroll bar of the Panel to the left of the Panel

I have a skin Panel with the following:

<s:Scroller id="contentScroller" height="100%" width="100%" 
                 horizontalScrollPolicy="off" verticalScrollPolicy="auto">
    <s:Group id="contentGroup" width="100%" height="100%" minWidth="0" minHeight="0"/>
</s:Scroller>

For the life of me I can't understand how to move from contentScroller to the left of its container.

I tried setting contentScroller x, y, up, left, down, right, the properties height and width to different values, but what I have in the extract seems to be the only way that it appears at all.

Based on the research, I tried this in the script of the skin:

override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void {
    super.updateDisplayList( unscaledWidth, unscaledHeight );
    if( contentScroller.visible ) {
        //contentScroller.verticalScrollBar.x = 0;
        contentScroller.verticalScrollBar.x = -contentScroller.verticalScrollBar.width;
    }
}

Or lines in the if block makes no difference as to where this thing is rendered. Here's a screenshot of my Panel:

And here's what I would do:

Thanks for the research!

I found a solution.

I removed the code in the script block and I went back to a scroller in the mxml.

I thought that I could set the vertical scroll bar by creating a skin based Scroller. In the generated file, I saw this:

Scroller unconditionally sets its skin's layout to private layout
implementation that handles the scroll policies.  Scroller skins can
only provide replacement scrollbars.  The skin's layout and
constraints or dimensions set on skin parts will not be honored.  To
gain more control over the layout of a viewport and its scrollbars,
instead of using Scroller, add them to a Group and use the ScrollBar component's
viewport property to link them together.

So I then changed my skin Panel to look like the following:

Finally, I added the following to the script block for positioning controls correctly:

override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void {
    verticalScroller.left = topGroup.height;
    contents.left = verticalScroller.x + verticalScroller.width;
    super.updateDisplayList( unscaledWidth, unscaledHeight );
}

adjustPopupWidth will not correctly work if there is a vertical scroll bar

Previously, I use "adjustPopupWidth", so that my JComboBox will enough width to display all items in the drop-down list.

However, I realize when he is present of the vertical scroll bar, 'adjustPopupWidth' will not produce a good width to display all the items in the drop-down list. This causes a horizontal scrollbar to appear as well (which is not what I want)

Remove 'Item 1' up to 'Article 7', results in a vertical scroll bar is not displayed. Therefore, "adjustPopupWidth" will work correctly.

It seems that the calculation within the "adjustPopupWidth", should take into account in the bar vertical scrolling. But how?

Thank you.

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.

TREE programmatically set vertical scroll bar

Is there a way to programmatically control the position of the vertical scroll bar of the TREE. I've looked through the nodes of property and do not see it. Thank you...

The closest thing I know is to call the Visible ensure invoke node on a specific item tag. Who will ensure that the node can be seen in the current scrolling selection. So you can call it on a particular tag to access a particular section. This has other side effects, such as the expansion of the section that contains the node you call it, is not an ideal way to scroll position.

Instability of the vertical scroll bar of the Panel

Win 7 Professional, SP 1, 64-bit on a Lenovo ThinkPad. The vertical scroll bar on the "Programs and features" Control Panel suddenly is so unstable that it is impossible to click on a title. Agitation is present both a Logitech mouse and ThinkPad track point device, well even more so with the mouse. The mouse driver is up to date, and the batteries are charged. The instability of the scroll bar does not seem to occur in all areas of the Control Panel, but appears on some menus of Windows Explorer, to a certain extent on this page (I have difficulties to access the submit button) and some Internet sites. Word so far. What do about it?

How to hide the vertical scroll bar in the Combobox?

Hello
I try to hide the vertical scroll bar in my combobox, because the number of items is small so it is not necessary that the vertical scroll bar is displayed.
I have a very strange behaviour :
When I view for the first time in my combobox, the vertical scroll bar is displayed - unless I have enough evidence to justify the appearance of the vertical scroll bar!
When I select an item in my combobox, the vertical scroll bar disappears (good behavior): it is always the same list of items!
I have try several solutions... the vertical scroll bar always appears!
If you have any ideas, it will be fun...
Thanks in advance
concerning
FM

Try the following:
```
  primaryStage.show();
        Platform.runLater(new Runnable() {
            public void run() {
                final Node scrollBar = comboBox.lookup(".scroll-bar:vertical");
                scrollBar.setOpacity(0);
            }
        });

Vertical scroll bar in a tree node
Hi friends,

I am trying to create a tree in Apex 4.0. I need a vertical scroll bar in my flowchart if no: values is greater than 8. For example, I have a tree with customers and sites. When I press the clients it will list sites for this customer. I need a vertical scroll bar is displayed for the sites if no: sites is greater than 8, so I can limit the size of the tree. Are there ways to achieve Apex 4.0. Any entry for this will be appreciated.

Thank you
NAV
You could combine all these properties in one class (inline of the div & fix Andy's IE styles) and assign it to the div.
```
  div.tree_scroll_div{
  overflow-y: auto;
  display: block;
  min-height: 10px;
  _height: 10px;
   }
```
+ Note: _hieght * gets ignored by all browsers except IE, it considers the height itself (CSS Hack). +

Dashboard area vertical scroll bar
I need to place a table bi report area of fixed size on my dashboard page. The report will be generally more lines that can be found in the space available if I want to use a vertical scroll bar to allow the user to view the entire report.

The report will be no more 10-20rangs so I don't want to use pagination if I can help it. I would like a vertically scollable region on my dashboard. Is this possible? I don't seem to be able to find previous examples of this but would be surprised that he has not done before.

TIA.
Paul
Hi Paul,.

You do not have this feature by default, we can do this by using an IFrame like this.

[Iframe src = saw.dll? Go&path=/shared/sample%20Sales/test/product%20Sales width = 300 height = 500 scrollable = yes >

[Note: replace space] [with html tags >]

In the path % 20 is used for white space and mention your path to the report, by adjusting the width and height, you can set the report accordingly

Two ways you can do,

Create table view, save the view.

(1) go to the narrative mode add the Iframe it and specify the path of the report and in the layout made add narrative display, remove the table view.

or

(2) to change the dashboard, add text, and enter the code Iframe the report path.

In both cases do not forget to check HTML.

Thank you
Vino
