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?

Tab control doesn't highlight when tabbing

I have to navigate through my application without a mouse, using the tab key, return key, etc. As I tab through the controls I've noticed that as a control receives focus it is outlined with a black box. This doesn't seem to be true, however, for the tab control. Is there someway I can get the tab control to be highlighted when it receives focus via the tab key?

There are ways you can do it by using attribute nodes. You can monitor the tab controls attribute node to see if it is in focus, then change color, size, or display the page, etc. Here is an example.

Keyboard Navigation with Tab Control

We have a tab control in a form and it has several pages.
On one of the tabs we show data from a multi row block, the first 3 columns are on the tab canvas, then we have a stacked canvas that scrolls left/right that shows the rest of the data. We fix the first three columns as they give context to the rest of the rwo that is scrolled within the tacked region.
Now the problem:
When focus is on one of the columns displayed on the tab page we can press CTRL-TAB and the tab switches to the next tab page.
If focus is on one of the fields on the stacked canvas CTRL-TAB doesn't navigate to the next tab page - it attempts to switch windows.
It looks like the items that aren't onthe tab canvas, but are on the stacked canvas, aren't party to the CTRL-TAB event?
Has anyone else experienved this problem? Or know of a work around?
Regards,
Bren

When I use CTRL-TAB just the trigger key-next-item fires. In our environment we use CTRL-PageUp/Down to switch the tab canvas. But I think the event that is really fired is key-nxtblk. So on forms-level I added the triggers key-nxtblk/prvblk that call my procedure next-/previous-tab-page.
In the when-new-forms-instance trigger I initiate a plsql-table, that has the following record type as a rowtype:
TYPE TabPage_Rec IS RECORD
(TabPage Varchar2(80),
First_item Varchar2(80));
So each tab page 'knows' its predecessor and successor. I then implemented two procedures next_tab_page and previous_tab_page, that iterate the plsql-table and set the canvas_property TOPMOST_TAB_PAGE to the requested value and navigate to the first item on the tab page.
That way you are mostly independent of the way your form is designed (blocks, items, order in object navigator). It is a bit of an investment and you have to keep it consistent to the way your form changes tabwise, but I found it quite handy.
Hope this helps.

Bettina

Tab controls

I have a program with 3 tabs using tab control. The first tab is a login
screen (because this will be used for remote fron panel use), the next is a
configuration tab and the last is the execution.
The login tab is an event structure waiting for a value changed on the
"login" bool button.
The config tab is a while loop that updates different settings which are
later being read from the execution tab and is also used for running small
test executions from within the config tab.
The execution tab is a while loop that reads settings from the config tab
controls and actually manipulates I/O ports.
So far so good. Now, when the VI is started, I switch to the login tab and
disable the others by use of a property node and references. Works well.
Once the user is l
ogged in, I disable the login tab and enable the others
and jump to the last tab. Works OK as well.
Problem: If I start the VI when any other tab than the login tab is in
"focus", that tab will continue running and you can never log in because the
login tab will never get "its turn" even though it will actually disable the
other tabs and put the login tab in focus. Also, I would like for the tabs
to stop running when I switch to another tab and continue when I switch back
to them, thereby only having one while loop running at a time.
Right now, if I stop the while loop in one of the tabs the whole program
stops.
Can anyone help me in the right direction?
TIA,
- Soren

I never thought of the tab control as an actual control, but more of a
display device. Anyway, you can make a local variable from the tab and
write a constant to it to switch between tabs.

Tab control in sequence

Hello,
I'm learning LabView and until I have started making applications I couldn't see how complicated it is.
I have tried to do VI to choosing in sequence some parameters. After many attempts to solve the problem, the VI it's working wrong all the time. Could you give me some leads how to do that? What architecture should I choose?
The idea is:
- after start VI only Page1 is visible and active
- when conditions for Page1 are correct we could push Next button and go to the next page
- Page 2 is visible and active and so on
- When we achieve Page4 (should be called "Summary page"), that ist summary page, which I not prepare yet
- in any moment we should have ability to go to any page using tabs
The problem is:
- the next buttons are grayed when I select previous page
- there are some problem with reliability, sometimes I push next button and nothings happen or page is visible but not active
I'll be glad about any suggestions.
Regards

Thanks altenbach for your post. It is very constructive.
I have changed my program and now it works as it should. It of course requires some cosmetical improvings, but it works. QSM is complicated for someone like me, who started with LabView.
FYI resetting partNo an foamNo is required to prevent from typing this values from keyboard and instead of it use barcode scanner. Barcode scanner works like paste function. Value just shows up in control.
I didn't know how to go to this same state many times - it is required for Key Focus all the time on proper controls. So I use timer to go periodically to cases depending on in tab I use.
Great thanks for your help,

Error: Accessing grouped objects in tab control

I have encountered an error where I cannot use/select objects within a tab control because they are grouped together.
If I copy/paste the tab control it shows them grouped and I can select them but as it stands in my program I cannot select the objects.
I would just copy/paste and work with that but I have property nodes and additional code for each of the 20 objects and would rather not have to go back and relink each property node and wire the new controls within the BD.
I am looking for a way of accessing the objects without having to copy+paste/recode anything.
Please note that there is a recent post about this tab control grouping error but is geared more towards adding an error notifier to LabView rather than how to fix the error.
Solved!
Go to Solution.

"Are these objects grouped because they are in a cluster or possibly because they were grouped using the reorder menu?"
The objects were grouped using the reorder menu on the front panel and then placed on a tab control.
The issue was that when I tried clicking on any of the grouped objects within the tab control on the front panel, nothing would happen.
If I double clicked, I would select the tab control on the BD.
I got rid of the bug by selecting everything on my BD and copying it into a new, blank VI.
Once I did that, I was able to access the objects that were grouped on the tab control.
Sorry for the late reply-- once I got it working I was only focused on finishing my task.

Highlighting current page on Tab control

Hi!,
I am using tab control with 7 pages. The page names are all in the same colour. Is there any way in which the colour for the name of the current page can be made different from the rest?
If your answer involves property nodes (or more advanced techniques) please be descriptive as I am beginner.
Also, which is the best book for inside stuff on property nodes?
I am using LV-PDS 6.1

It isn't possible to assign a key to more than one control, since then
it would be pretty unclear which control should out-of-the-blue receive
the key. It is possible to catch key events and perform and action
based upon the key press. Another option is to set
the key focus to the
next logical button in your progression. If the focus is set to a
button, then the space bar, enter key, etc all work.
Since you are asking for comments, the UI you describe sounds a bit odd
to me. A sequence of buttons that the user is required to click in a
given order? You might want to compare this to an indicator showing the
stage and current results, and one more button that says Next. Tie the
key navigation shortcut to the single button, and each button press
moves to the next stage. You might want to add a Cancel or Stop button
if there is ever any need to break out of the sequence. Finally, this
is pretty close to a wizard that allows the user to go both directions.
If it makes sense to reverse and redo a step, add that button too and
you have a very standard UI.
To build a wizard, use a tab control with a page for each stage. Hide
the tabs, and modify the pages by adding or subtracting on the value.

How can I set the tab order of text box controls on each page of a tab control?

I need to be able to select the tabbing order of individual controls on a single page of a tabbed control. How??

In LV 6.1 an up you should be ablel to right click on the edge of the tab control when the tab-page in question is selected.
The bttom selcetion in the pop-up is "Reoder controls in page..."
selecting this option will switch editing modes to allow you to specify the ored, just like in a cluster.
I seem to remeber in older versions you had to drag the tabable controls off the tab control, specify the tabbing oder and then drag them back on. The oldest version I have on this machine is 6.1 so that all I can speak for at the moment.
I hope this helps,

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"?

Make the tab control a control and not an indicator. If you want to write
to it you need to create a local variable.

Data Origin Types not filled in the tab "Control Data" of BP interface

Hello experts,
I have loaded the clients from ECC6.0 to CRM 4.0.
Before I have loaded the clients I have maintained the data origin type for the BP in spro -> cross application components -> SAP Business Partner -> Business partner -> Basic settings -> Data Origin -> Maintain Data Origin Type.
After I have done the load initial of clients, the field "Data Origin" is empty in the tab "Control Data" in BP interface. If I do F4 in the field appear the configuration that I did in spro appear.
For this field will appear filled I'll need to do more configurations in spro?
Best regards,
Mary

Hi Mary,
The middleware does not fill this field in BP master data. You can maintain data origin type in SPRO, however the mBdoc does not use this customizing in order to fill this field.
Please try to use the BADI CRM_DATAEXCHG_BADI in order to fill this field during master data download.
It hope it helps.

Horizontal tabs when they are on the left side of tab control

I have a tab control for a touch screen where I was going to use buttons along the left side to change tabs, and hide the tabs. However, I realized I can put the tabs on the left side of the tab control and remove my buttons all together. Only issue is, I would like them (along with their font) to be horizontal, not vertical as they are shown in my screenshot. Is there a way to change this?

It's a really poor design aspect of tab controls that the text is sideways when the tabs are on the left or right side.
I've looked into it and found no way to re-orient the text.
However you can put images on the tabs instead of text, and the images can be of text (correctly oriented of course).
The attached code can be used to generate such a tab control.

How to hide a tab in a Tab Control by Property Node?

Hi,
I have a Tab Control in my Front Panel. So, using a array of LEDs, I would like to hide some tabs, probably using Property Node functions, but I can't find what option do it. Is it possible?

Thanks Macro! I came to the forum to find a solution for this exact problem, it's nice to find it already laid out for me so clearly.
