Tab control and Multiline mode property

We are using tab control with multiline mode property true. We have around 20 tab pages and because of multiline mode property items are displayed in three rows. Annoying thing is whenever we do selection of a tab in first row tab items get rearranged
and my selected tab will come to last row. Is any one facing the same issue. Please suggest me.

The selected Tab has no bottom border (assuming top alignment) and so the selected tab should always merge with the tabpage. This is why the row with the selected tab always moves to the tabpage border. If you don't want this behaviour then set the tabcontrols
appearance to Button and the rows will not change when a tab is selected.

"Tab" control and Tab order of controls inside the tab

Hello everybody,
I have created the tab control with 6 'tabs', inside every tab I have some controls, like edit fields etc. I wanted to make an order of controls for every tab, so I have selected the option "Tab-order settings" from menu "Edit" (sorry for translation, I use non-English version of LabView), and tried to set the order. After saving it with "OK" button it turned out that the order is not changed. Simple it seems that the option doesn't work for controls in tabs. Is this a bug or do you have a solution for this?
TIA,
Yazilim.

Sorry LabviewGuru, but I haven't found anything concerning Tab control and tab order inside it. Of course, I have found the topic "tabbing through front panel objects", but it simply describes how to change order for standard controls, not for controls which are inside the Tab control. But maybe you have another, extended help? So can you please copy and paste to discussion forum message this part of your help which concerns the Tab control and tab order, and then send the message?
TIA,
Yazilim.

Tab control and content

on my main page i have a five tab control, and each tab has its own content. below the tab control and external to it is another region containing a dynamic page portlet. this region faithfully shows its contents when 4 of the 5 tabs are displayed. when the 5th tab is displayed, it is empty. i've cleared the cache numerous time with no effect.
if anybody has any ideas please pass them on.
thanks,

Tab Control and Property node

Hi everyone,
i'm trying to create a vi that is able to run more than one test simultaneously but so far i only succeed in using the tab control to control case structure.
What should i do to change the vi to suit my objective?
thanks for any insight.
Currently using labview 8, winsXP.

The tab control is just something that tells which page is visible. It has nothing to do with the execution of code. To have multiple things happening at the same time, you will need several while loops happening in parallel with each test in its own while loop. Right now your code (and maybe its on a section of screen you didn't copy to the .jpg) does not show any looping whatsoever.

Possible bug with Tab Control and Context Help?

I created Description and Tip text for each Tab of a tab control I am using on my front panel. I have a subVI that is called by selecting a menu item from my main front panel. The subVI's front panel also has a menu system and a Tab Control. I have Description and Tip text written for each of the tabs on the subVI's front panel.
When I enable context help from the menu of my main VI, the proper help text shows up for the tabs on the main vi and, when I bring up the subVI's front panel, for its tabs as well.
So far so good...
Now I builld the application and run it as an executable. For ALL of my panel tab descriptions, I get the tab's label in bold text, but no description (just a blank area).
Is this a bug in LabVIEW?

I'm still seeing this behavior in LV8.2.1. Does anyone know if/when it was fixed? Also, my tip strips show up in the corner of the monitor when I mouse over a tab (in both the executable and the development version).
I see it still even in 8.5.
The Help part of the bug is still NOT fixeed by NI.
But I dont get the tool tip appearing in the corner of the monitor, it is showing up as usual.

Hi,
Aaa.. the blue box is an Enumeration Constant. Because I've used something like this you cannot change the name of the Tabs. To fix it:
Simply replace these two Constants with Numerical Integer Constants 0 - for the first Tab and 1 - for the Second Tab. It took me a while to understand what you wanted to say . This way you can change the name without getting an error.
I've rewritten the entire VI in order to be clean (I was ashamed of the previous one). You can still use the first one.
Just an advice: Even if it looks at the beginning more complicated try to use Event Structure all the time when you have buttons. The use of loops with buttons and if structure (like in your vi) creates a lot of problems and it's hard to debug.

How do I create more tabs in my tab control, and place graphs/charts on these.

It has to be done in the program depending on a setup file.
This is due to that I have from 2 till 100 graphs/charts needed to be shown. One graph/chart on each tab.
How many tabs I need comes from the setup file.

This is not really a goo way to approach this. 100 tabs ouch. This would not only be a nightmare to code and keep up to date but I think it
could be done. Here is an examlpe of how to do it in LV 8 and a file saved for previous into 7.1 it seams to me it was easier to do in lv 7 but I cannot be sure since I no longer have 7.0 or 7.1 on this machine.

Executions on both tab control and list tab

In my TestStand OI, on the left exists the listbox that contains the Sequence Files and Executions. On the right is the tab control that shows the Test Sequence only. Then, when a sequence file is run, the Executions and Report tab appear. What do I add/change such that the Executions tab is displayed next to the Sequence tab at all times.

Hi mrbean,
I am not quite sure how this will benefit you as the Execution tab is solely for executions and when you start up your OI, there is no executions you are running. However, if you open up the Full OI's block diagram, you will notice a subVI called "Full OI - Show Appropriate Tabs". This is the VI that sets when the tabs are visible. If you change up that case structure for the ListBar (setting the different boolean constants), you can dictate which tabs are visible.
Hope this helps!

Tab control and Ring???

have a tab control, where results will be displayed on tabs A,B,C
in my vi. i have a ring; of options 1,2,3 when i change them i get various results. (A-C correspond to 1-3)
is there a way when i select '2' on my ring, it will bring up tab B??
hope this makes some sort of sense.
Thanks in advance.

The pages of a tab control are inherently an Enum.
If you create an Enum control, and wire that to a local variable of the tab control, then the Enum control will change to that page within the tab control.

Tab controls and team develop enviroment

I just tried to insert a control to the form and I realised that there is tab controls available to insert.
I would like to know does DW have tab control, if yes, any way to access it?
by the way, does DW have version control for team develop enviroment?
Your information is great appreciated,
iccsi

Thanks for the message,
Do you mean that I need plug in a version control or CF has its own version controls?
If it has how can I access it?
Thanks again for helping,

Customizing Tab control and Enum

I am trying to do two things here regarding customizing controls.
The first is to add a down-arrow decoration to an enum so that it looks kind of like a menu ring (click the down arrow to drop down the selections). If I simply paste it on top of the control, the decoration will intercept the click and not drop the selections down. I want to have the control colored, so putting it behind and making the ring text background transparent doesn't really work either. If I make it part of the "Ring Text" background element, it's fine for that one size, but if I resize the control it gets all stretched out.
The second is to modify the "Page Labels Display" in a tab control. The only selection allowed when attempting to customize the tab control is to "replace" the page labels display with a different control type. Every enum or ring that I've tried has simply beeped at me with no replacement. I would really like to get the aforementioned Ring-styled enum in this box as well.
One other quirk that I haven't noticed before (Maybe since I haven't done a lot of work with tabs in the past), but when I'm trying to get context help for anything inside of a tab, the only thing that shows up is the context help for the tab itself. Is that "working as expected"?
Regards,
Mike

hi Mike,
there is another discussion forum covering your first question, but it sounds like your best bet would be a ComboBox:
This will give you the appearance you want, and behaves the same as an Enum.
In order to set up a similar drop down menu of the pages of a Tab Control, it will be a little more indirect. Take a look at the attached example, which populates a combo box with the pages of a Tab Control.
That quirk you mentioned with the Context Help and Tab Controls is a known bug, and is fixed in LabVIEW 2011. Hope this helps!

Bug? Tab control breaks graph autoscale (+workaround)

I had this really annoying problem where two of my graphs did autoscale and the other two didn't... Although all the code and graph properties were exactly the same.
I finally figured it out... The graphs are in a tab control. And only the graphs that are on top get autoscaling. Labview 'forgets' to autoscale the other graphs when you show those other tabs. Even when I use a property node, I can't force the graphs to autoscale, unless they are on the showing tab.
Feels like a bug to me.... I can understand that graphs aren't updated/autoscaled when they're not shown for performance reasons... but I think the axis should then be updated/autoscaled as soon as the corresponding tab is shown. And it certainly would be nice if the axis does autoscale when I explicitely ask for it using the property node...
Now that I understood the problem, I could also make a work-around. I made a 'value changed' event for the tab control, and put the property node autoscale code in it. That way, I ask for an autoscale right after showing the new tab page. (See attached vi for example of the problem and work-around.)
The workaround works fine... but I think that this should be default built-in behaviour for graphs in tabs that have the autoscale enabled.

Hi Anthony,
This is a known issue that was partially fixed in LabVIEW 8, which you appear to be using. By partially, I mean that the behavior only persists when you update the value of your graph using a property node (either Value or Value Signaling). If you update the value using a direct wire connection to the graph terminal, or using a local variable, then the problem goes away. I would recommend using either of these methods, because they will fix your issue. Also, in general a direct wire connection or a local variable will greatly improve LabVIEW's efficiency in terms of updating the front panel. The only situation where this fails is if you need to update your graphs from inside a subVI using control references.
Because that last note is a very real situation, we will notify R&D of this matter so that they can investigate this further. Thanks for bringing this to our attention.

Tab Control Property Node unknown error on TPC

I am using Lab View 8.6. I am programming an HMI onto a TPC 2106. I am using a Tab Control and it workls fine. The problem is when I add a property node for the tab control to the block diagram. I get an unknown error no matter which property I choose or if it is read or write. I tried it on a vi destined for the computer and it works fine. It seems to be an issue with the TPC 2106 as the destination.

Hi vrundquist,
When compiling a VI for a TPC, there are many properties of controls and indicators that will not be supported. Which properties specifically have you tried? I want to be sure you are choosing a property that should be OK. For example, try the Visible property. Also, is there anything else going on in your code, or can you reproduce this with a VI that has nothing but a tab control?

Can you print all the tab control's contents and include the tabs?

We are trying to generate a report that includes the contents of a tab control (graphs, text). Using the Append Control Image to Report.vi, we are only able to print out the active tab and the tab is cut off of the image. How can we generate reports that include all the tab pages and their contents and include the labeling tabs?
Thanks in advance.
Jim

I do have a workaround for makinging the prints but it looks like some sort of cropped screensave that cuts off the tabs. In my sample I was printing out 3 of the tab controls and you can see there are three by the cut off tabs. Is there a setting to allow for more of the graph and its surroundings to be "captured"?
