Can I control pages in tab control with case structure?

Hi there!
I'm quite new to Labview and my company wants me to make some programs for testing of electronics. I'm currently working on the GUI and I would like to control three pages in a tab control with buttons.
I only got the base package of Labview 2009 so I can't use Event structure.
If you open my .vi you can see I have a tab control with three pages. In the first page I got a "Start" button that should open the next page in the tab control. In the middle page I have a "Tilbake (Back)" button that should go back to the previous page. The button called "Lagre (Save)" should work as a next button and go to the last page. On that page I have a "Tilbake(Back)", "Ny test(New test -> go to first page again)" and "Avslutt (Quit)".
The buttons under the tab control where something I copied from an example just to try out. That works perfectly, but I cannot edit the Event Structure from the example.
Is this possible to solve with Case Structure? Or maybe there are other solutions? Feel free to edit my .vi if you like
Thanks for the help!

Hi again!
Well it solved my problem, but I got a strange error while running my program.
When I press "start", the tab control changes page. When I press "tilbake(back)" it is totally random how many clicks it is necessary for it to change back to the first page. It can be from 1 to 20-30 clicks. Which is very strange since all other navigation buttons works perfect. "Tilbake(back)" button on the last page works correctly and has the same structure as the "tilbake(back)" button on the middle page.
I have tried all the different options on how the button will response on a press.

Tab control with 2 pages

I want to create a Tab control with 2 pages, in each page there are 2 buttons - "OK" and "Cancel".
If on Page1, "OK" is clicked, Page2 will be disable and greyed, until "Cancel" is clicked. And vice-versa for Page2 buttons.
How to do this?
Thanks in advance...

Hi Splee,
Please view the attached vi, I believe it's doing what you've asked. You can invoke properties using property node in order to change the value of variables.
Hi Simply_me check your Vi will it really works. To make this VI in working condition you have to do some more coding in your code.
Check your page selection technique.
Hi Splee,
First you have to find out on which Tab Page user clicking the buttons, the all operations you have to do on other page.
Once your page is disable you can't access the controls of that page. As Geeta says make a code using event structure with Tab Control property and invoke nodes.
You have to do some coding to achieve your requirements.

Tab control with a case structure

I am having trouble getting my tab control to work with case structure. I have 4 tabs that i want displayed on my front panel, each with a separate graph. When I click on any tab besides the first one there is nothing shown on the graph. I think i have some wiring issues. Any ideas?

See also this and this discusion. Most of the time, tab controls don't need any code.
(You also have a couple of breakpoints (one on the entire diagram and one on the while loop). Make sure you remove them. Look for the red outlines.

Embedding SAP standard iviews in Tab controls with Web Dynpro

Hi,
I would like to develop a Web Dynpro application using TabStrip control. I have to display SAP standard iViiw(ex: KM navingation iView, expore iView) in each Tab. How can I embed iViews in each Tab in Web Dynpro.
Thanks
Tats

Hi,
using the IFrame UI element to display an iView inside a WD application will not work in general as the iFrame is reloaded after each request executed for the embedding WD application. In case that the iView is "stateless" this restriction is perhaps not so hard but you should nevertheless make sure that the ongoing reloading of the iFrame does NOT create new sessions again and again on the server-side for the iView running in the iFrame.
With the next NetWeaver release we will provide a capability to define page layouts using WD components. Doing this it will be easily possible to define a page layout showing several iViews in different tabs of a tab strip.
Best regards
Jochen

Problem while creating Table control with wizard

Hi All,
I am using the table control wizard.
Following is the declared data :
TYPES: BEGIN OF test_str,
        name TYPE string,
        city TYPE string,
      END OF test_str.
DATA: lt_str TYPE STANDARD TABLE OF test_str,
      ls_str TYPE test_str.
I activated the program after declaring this..
then I created a screen.
while generating the table control , i give the internal table name as lt_str and work area as ls_str(both of these are also coming in F4 help) , i am getting the following error :
the table work area ls_str does not exist or is not a structure.
Please help.
Regards
Panneer

HI Selvam
In the wizard please choose the radio button internal program table. I hope you might have choosen the dictonary table.
And activate the program before generating the wizard.
Please try this and let me know if any issues.

Graph range problem with tab control

Hello.
I am using LabVIEW 8.2.1
I have five XY-graphs in a tab control, with five tabs. One graph in each tab. When running, theese graphs is constantly written to, but the user is only allowed to watch one at a time.
The program also contain a maximum&minimum chart, containg the maximum and minimum value for every plot in the viewable part of the graphs. The user can zoom in on a graph, and then watch the max&min values in this picture. The values are calculated by taking the range to each graph, and use theese ranges to cut out the viewable part from the input data to the graphs.
The problem is, that the program only see the last viewed range. If I view a graph in a tab, the max&min values for this graph is correct, but the four other graphs dont get the correct values. The graphs data is written correctly. It seems like the ranges from the "hidden" graphs dont get updated when not viewed. Does anybody know how to fix this problem?
I have uploaded an example to this problem. See how the range just freezes on the not viewed graph, even the two graphs is exactly the same.
Thanks
Fredrik, Norway

Frederik,
the reason for your issue is autoscaling. If the graph is not drawn, autoscaling will not take place, so you will not get any correct values, you will get the last autoscale-values.
The behaviour therefore is "works as intended" since it reduces CPU usage.
So the best way to work around is something like seen in the attached VI: you should compute the scaling for each graph on your own and use this to update the scales as well as the indicators (which i left out in my VI).
hope this helps,

Tab control problems

I made a peogram to look at the file name back and forth. seefile.vi works great. I also need to do further work after seefile.vi. I created TAB control with two pages. Simply I duplicated seefile.vi (page 1) as page 2, which is seefile1.vi as attached. Now I can not run it right. The problem is Next Buttorn can be used once and then it is running for ever.
If I delete all content in page 2, it works great again. My question is what in page 2 can cause Next Button in page 1 frozen??? Or I did not figure TAB control right.

I don't see any Tab control, I don't see page 1 or page 2, I don't see a Next button, and I don't know what you're talking about. You will have to do a better job at explaining what it is that you want. Also, in one of your block diagrams, you have a loop condition with a False wired to the Stop sign. This will cause your vi to run forever.

Text Tool on Tab Control Bug?

I'm trying to create some free labels on a tab control with the text tool and I've found the postion of the text insertion point is off. When I click anywhere on the tab the text appears a few inches above the point that I clicked on. The tool is working fine off the tabs and when I go to select the previously written text with it that works too. I've noticed the insertion point jumps around and is often in a new place when I open a new VI and drop a tab control down. I have free text on tabs I created last week so I know it wasn't doing it then. Has anyone else seen this behaviour?

Tab control bug?

I have a problem with tab control which has been bugging me for a long time and i can't seem to solve it.
I have a tab control with 4 pages, A, B, C and D. All these pages are invisible at the beginning. Once the user selects the page from the custom run-time menu, the appropriate page then showns up (PageVis=True). Now, when i try a few more times switching between different pages, some pages showns up together with the intended page. Once i click the correct page's tab, the others disappear. Now this is a problem because when a user is using page A, i do not want he/she to be able to access other pages.
Can someone help me before i kill someone? Thanks.

The order of the property nodes is not defined because you have no dataflow between. Execution order is not defined by where a function is on the block diagram (left, right, top bottom), but how data is connected. You have no connections between the properties so they execute in parallel and you have no way of knowing which one will actually execute first. The simplest way to enforce dataflow is with the error in/error out connections. That is shown below. also shown is one way to select the active page. I used a local variable but if you make the tab control an indicator instead of the default control, just wire a value to the terminal itself.

Modifying tab control behavior

I have been toying around with a tab control trying to customize it to
suit my needs. I currently have a tab control with a transparent
background (since it is within another tab control, and I find it looks
far better without any borders or anything) that cotains 4 tabs.
I'm wondering if there's any way to change the colour of the different
tab texts, based on the selection. For instance, if you click on
tab A, which has the text "TAB A", is there any way to change the
colour of that (and only that) text? As it stands, it's somewhat
difficult to distinguish from the other tabs, since all of the tab
outlines are transparent, the text only shifts to the left a little.
I've played around with the properties, but with no success. I
feel like this probably isn't possible, but if anyone has any other
ideas of how to distinguish the text, I'm all ears (or eyes I guess).
Thanks for your help.

Two suggestions: either hide the tabs and create other buttons to handle the switching of your tabs (what I do when I want to create a more elegant interface where tabs "don't make sense") or change the FP colors of all the other pages. That way only your page will have a transparent background and it's label will stand out.

Tab control - takes long to change between tabs

Hi everyone,
I am using a tab control to display a set of results on each tab. So, I have a tab control with three tabs and each tab consists of 16 indicators which are updated with values. Now, when I run the program, it is taking a long time to switch between these tabs. For instance, if I am currently on Page 1 and then I click Page 2, it takes around 5 seconds to change the tab. I know this should be like this but I cannot understand what is happening.
I need help, please. I know it is a silly question but I cannot make heads or tails of it!
Thanks!

I would also recommend to streamline the code a little bit.
For example the cases in frame#1 differ only by some small operations. All that belongs inside the case is the code that differs. none of the local variable seems to be necessary. All that belongs in the smaller cases are the colorbox constants (might be easier to index into an array of colors). If you autoindex on the For loop boundary, you don't need to wire N and you can eliminate the "index array" operation.
In frame #2, you could autoindex on arrays of references, all in a single FOR loop (same for all the initializations).
You have race conditions. Initializing all the colors (to the right and left of the sequence structure) all occur in parallel to the sequence structure. You should create a data dependency to ensure things occur in a defined order.
You can probably eliminate all these hidden indicators and associated local variables. The wire is the data!

Tab Control Focus

I have a tab controls with two tabs. I put a lot of indicators under each tab. During run time, the indicators will get updated, and the user can select which tab he wants to view. I only want the user to change the tab order. It seems like when the user is on the 1st tab and the indicators on the 2nd tabs are being updated by the program, the problem will switch the tab control to the 2nd tab. Is there a way to disable that?
Kudos and Accepted as Solution are welcome!

You'll have to show us a VI. I have never seen the tab switch from one page to another unless either the user clicked on a new tab, or the program programmatically changed the tab. Generally for me, the tab control is never read from or written to inside the VI, it is just used as a mechanism to separate and organize different parts of the program. Updating an indicator on a non-shown tab should not be causing that tab to be switched to.
How do you want the user to change the tab order? Do you mean that you want to swap the locations of the tabs so that page 2 moves to the left ahead of page 1?

Is there a way to add a LED indicator to the tabs in a tab control

I have a tab control with multiple rows of tabs. I would like to know if there is a way that I could add round LED indicators to each of the tabs so that I can quickly see the status of each page. If I only have one row I can just allow for my LEDs to "hover" over the tab, but this does not work if there are multiple rows since the tabs change locations when they are selected. Does anyone have experience with this?
Thanks in advance!
Solved!
Go to Solution.

I decided to take some time (probably way too much time!) to try this out and prove it would work. See the attachment in LV 8.5.1.
I used arrays and control references to make the code as scalable as possible. I added several spaces at the end of each label name so that there was some room to place a very small LED.
The trickiest part (and I would save this until the tabs are named, laid out, and the overall tab control is sized) is to find the best location and screen coordinates for each LED.
I discovered for best looks, that the LED should jump up and to the left by 2 pixels when its specific tab is selected, just like the label text does. Otherwise the LED's just jump around on the screen to match whatever row its respective tab is on.
I have the timeout event randomly turning on and off the LED's, but that would actually be handled by your other code and whatever events determine whether the LED should be on or off.
