LV RT and tab controls

I'm still coming up to speed with LV RT and had a question. I
understand the general philosphy of separating the UI and the
deterministic part of the RT engine, but haven't gotten around to fully
implementing that yet. As a first step, I was using the front panel of
the RT application to show all kinds of configuration info and live
data. I put a tab control on that panel to organize it. However, when
I download and run the program from my host to the RT chassis, the tab
control is unresponsive and I can only interact and see those controls
on the first tab.
Is this a known limitation of RT (LV 7.0) - that you can only see
and interact on the host with those controls that are visible when the
program starts?
TIA,
Dave

It might seem that way, but that's not what's going on. When you deploy to
the real time platform, those sockets that pass live data to the GUI on the
host side either slow things down enormously, or take place with such low
priority that they never or rarely happen. You need to religiously keep
your real time process from sending live data to the GUI!

Obscured Labels - Graphs and tab controls

In LV 2012 new options (Preferences or Options on the Mac) allow placing labels on new controls and indicators in various positions. I have noticed that for graphs and tab controls some of the options result in obscured labels. See the image below.
The preferences are set as shown:
When a graph is dropped, the label is superimposed on the plot legend display.
For a tab control everything is OK until enough tabs are added to create a second row. Those tabs are behind the label. I can understand some reluctance to move a label automatically after it has been created (in the tab case), but I think it would be better moved up than obscured. Perhaps if the programmmer had repositioned the label before the tabs were added, then it should not move automatically.
Is this a bug?
Lynn

Hi Lynn,
I've played around with these settings and I get the same results. It seems with the tab control that the new row of labels is pushed to the top by default, and the label will be obscured unless it has been placed to the bottom or side of the control. After looking into things further it seems that this is the expected behavior rather than a bug. You're welcome to post your idea to the Idea Exchange as a feature request, it seems like that might be a better way to handle the label positioning in the future.

Bookmarks bar and tab controls not working in mobile Safari on iPad2

The bookmarks bar as well as tab controls in Mobile Safari on iPad 2 are not clickable. Only the topmost nav buttons work. This persists through reboots w/Safari closed via mem manager, and a system restore. What do?

closing Safari via the taskbar
or having done a reset (unless that is what you mean by a reboot)
"This persists through reboots w/Safari closed via mem manager"
That is obviously exactly what I meant. How does one reboot an iPad without "resetting" it? How does one do a system restore without "resetting" it?

Two instances of quirky behavior: array size of empty array and tab control freeze

LV 7.1
Array size of empty array. Adding empty arrays to an array of higher dimension produces a fantom array of non-zero size.
Tab control freeze. An event structure with checked 'lock front panel until the event case completes' option permanently freezes the front panel in certain special circumstances.

Whew, let me look at this tonight after I activate the 4D module in my brain.
(I think it makes sense, though ) Generally I look at the product of the dimensions array to determine if an array is empty. You can initialize a multidimensional array with some dimensions at zero and it is reproduced nicely in the array size output. Also the "Empty array" tool correctly identifies it as empty, even if some dimensions are nonzero.

EVENT_MOUSE_POINTER_MOVE and Tab Controls

Is there a way to get EVENT_MOUSE_POINTER_MOVE events in a callback whenever the user moves the mouse over a panel that's part of a Tab control? Basically, I don't see a way to define a panel callback for the panels that are made inside of a Tab control, which would be possible using the old EasyTab way of doing things. I can define a panel callback for the panel that the Tab control is on, but that callback appears to not receive EVENT_MOUSE_POINTER_MOVE events when the mouse is over the Tab control. I can put a callback on the Tab control itself, but it seems to only receive EVENT_MOUSE_POINTER_MOVE events when the mouse is at the edge of the control. It seems like there is something obvious that I am missing here, but I can't figure out what it is. Thanks!

You can get the panel handle of the desired tab, and then install a panel callback for that panel. I've attached a sample program. Hope this helps.

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!

Navigate pages of tab control with radio buttons

hi guy,
i need to navigate 7 pages of a tab control container usings custom buttons. that is, when i click on a button, i takes me to the specific page on the tab control container.

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"?

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.

"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.

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.

Tab Control - change page name and color

a)
Is there any possibility to
change the names of pages in a Tab Control programmatically?
(I want to change the names in a runtime version depending on the user
selected language. Therefore I can't use the Import Strings function.)
b)
Is it possible to change the colors of a Tab Control ?
Robert
(using LV6.02 on WinNT)

Hello,
If you use the property "Independant Label" of the tab, you can change the TabCaption.
You cannot use blank names.

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.

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.

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.
