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!
Solved!

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 shows wrong display for selected tab

My computer crashed when I tried to post this earlier, so I apologize if the first post actually shows up.
I have seen this for years so it is nothing new, but I don't remember seeing it in any release notes (sorry if I missed it).
Upon loading the .vi (or as an executable), the .vi shows the wrong page for the selected tab. After selecting a different tab, the control works fine. Also, if you create a property node to read the tab value, it matches the displayed page....just the selected tab seems to be incorrect.
A work around is to select the default tab before saving the .vi, but why is this happening in the first place?

Hi Stephen,
The erroneous tab display is something I see on most of not all of my code that uses a tab control (each is a typedef).
What change would I make the the typedef? If I disconnect the tab from the typedef then I will loose the advantages of using the typederf...I will stick with the workaround like I have for the past 3+ years.
Isn't this a LabVIEW bug since the displayed tab is not equal to the value read from the control? I have not tried it on this example I posted but in the past, writing to the control does not fix the displayed tab (writing the control may not work since I wrote the same value that LabVIEW thinks is the current value, but the displayed!=actual).
Thanks,
Todd

Tab Control will not build properly if "tab location" are on left or right.

Using LV 6.1, try the following;
Create a new vi. Place a Tab control,(from the Arrays & Clusters palette), on it's front panel. Right click on one of it's tabs and follow "Advance-->Tab Location-->select Left". Save your vi. Create a build for it and run the program. Does anyone know of a fix for this? Does this also happen on LV 7.1?
Thanks

That is good news to me. That probably means I am doing something different here.
What happens to me is that when I create an executable of a VI which uses a Tab Control that has had its tabs set on the left or right of the control instead of its original location, the tabs are now all stacked on top of each other at the very bottom and the text labels are not shown.
I don't know how else to explain this. I've attached a sample of a vi I used to test this. Please take a look at it.
Thank you,
Wil

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"?

How can I get around the find bar no longer being shared between tabs in the latest version of Firefox?

Previously, one could open a new tab and the find bar would remain at the bottom of the page from the previously opened tab. So, for example, I could search for something in a tab I open, open a new tab and the same find bar would be at the bottom so I could search the new website for the same thing. Any way around this?

Hi,
This function is no longer officially in Firefox, however this addon replaces it: https://addons.mozilla.org/en-US/firefox/addon/find-in-tabs
Hope this helps!

Can you change tabs on a tab control by using boolean buttons?

Need to change tabs by pressing a button instead of using the actual tabs.

Absolutely. First create a local variable for your tab control. Then poll your boolean to tell when its value has changed. Finally write a value to the tab's local variable to change its tab page programmatically.

How to create tab control within a tab control?

So I'll lay out the basic outline of my project. Right now I have a tab control which scrolls through each of its tabs 1 second at a time. It does this until the user presses the pause button, the the scrolling stops and the user sees the tab that was onscreen right at the moment of pressing pause. Now what I want to do is have a separate tab control which comes up automatically once the user presses pause instead of the 1st tab control just stopping as it does now.
Or alternatively is there a way to programmatically tell the tab control to stop on a specific tab once pause is pressed? Even turn on and/or off the tab labels upon pressing pause? I've been informed I can accomplish this by way of using "nodes" I think is the term, but have yet to successfully implement anything.

On Pause value change-event, change tab. To lock, either disable tab control (which'll also disable its controls), keep track of pause status to return to this tab if changed (in the tab change event) or place a transparent image over the tab selectors (which'll stop attempts of clicking them).

Tab Control Solution for my project

I am implementing the program acquisition and signal processing. The program has two parts are Aquisition and Analysis. I want to integrate into a program should use the "tab control". Each program section have some special processing so I do not know how the tab control to not conflict.
+ Aquisition Tab will perform receiving signals continuously from the computer through the COM port, recording the file by "write the measurement file" .tdms
+ Analysis performs the "read measurement file .tdms", which have been recorded to display and several other process.
I expect people to help to have appropriate solution for the tab control for my project.

Hi ducta,
Ofcourse you can integrate the tab control in your project.But please clarify me on this question.
Do you want to use the tab control in a toggling fashion?i.e. initially keep the tab in acquisition and then change the tab in analysis and then again change it to acquisition.If you are using this way then only it makes sense as the acquisition and analysis will hand in hand according to the tab control.

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?

A pop-up window says I have mutiple tabs but I can't switch between them

Was making payment in popup window. Asked to print confirmation and pop-up window went blank (did not print). Cannot recover payment confirmation screen. When I try to close the pop-up window it says there are several tabs. How do I switch between tabs in the pop-up window? There are no menus nor drop-downs.

I want to make sure you're using the auto-update system, because that's the safest most reliable way to go, and it shouldn't appear in the download manager, so I lets make sure you're doing it right. <br/>
This is a screencast I made a couple of years ago. It refers to 3.5 and 3.6, but the steps are still the same: http://ilias.ca/screencasts/ISUHD45.mov
If that doesn't work, then maybe your Snow Leopard account doesn't have permission to update applications?

Is there a Keyboard shortcut to: a) Switch between Tab Groups? b) Switch between matching Panorama search results?

a) Switching between tab groups would improve my workflow. Like Alt+(Shift+)Tab to switch to next/prev Tab. Cmd+Shift+W/R wold be another possible option beside the Cmd+Shift+E for Panorama.
b) When searching in Panorama Tabbing between results would be great.

CTRL+SHIFT+E got me to the tabs group "menu" so you could pick which tab you wanted. it's all explained here:

Error in Nested Tab controls

I seem to have found a bug in nested tab controls. If one nests a tab control in a tab control, the remove page uses the index of the parent tab control to determine which tab to remove of the child tab. I use Labview 6.1 on Win2000.
In addition, it seems that I cannot add a tab control to a cluster. This seems to be a "feature".

Jazee,
Apparently, this seems to be a bug for nested tab controls.
You can't add a tab control to a cluster.
You can keep the value of the actual choosen tab in a cluster by converting it to a number and put that number in a cluster.

Tab control

Hi all,
I have a tab control with 3 tabs. I was wondering how I can do the following:
1. I want to show only 1 page of the tab control without the tab header name when i start the program.
2. When i hit ctl + shft + , I would like my tab control to display all 3 tabs with the header.
3. When i hit ctl + shft + , I would like my tab control to display only the first tab with no header.
Has this ever been done? Can it be done?

Sure. It doesn't do exactly what you want but should be simple to modify. To control individual tabs, you use the read only property pages. This returns an array of references. You use an index array function to get a specific page. For example, if you want to manipulate page two, index element 1 of the pages property. The returned reference can be used to create properties for just page 2.

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.

My tabs abruptly change from tabs to new firefox windows.

When I have several tabs open to different website, clicking on a particular tab frequently leads firefox to change the tab into a new instance of firefox, that is, a new window. This began happening a few weeks ago and seems to be happening more frequently. It happens on different computers also.

Welcome to the discussions,
a manual backup will help:
Disable autosync in itunes, connect your phone, right click on it in the device list and choose backup.
This will save data, pictures taken with the phone and settings to itunes. See what's included in this backup here: http://support.apple.com/kb/HT1766
Transfer your purchases the same way to copy all apps and bought media from the Store to your computer.
Set up at least one contact and event on your computer to be able the merge your calendars and contacts after your phone got wiped during the first sync.
The rest of the data can be restored from the backup you made.
