Cannot drag an indicator off a tab control page

I inherit this VI and try to change certain controls in the tab control pages. But the controls are locked together, every time I select an item on the control, everything is selected. And when I make a new string indicator and drop onto the page, I cannot select or delete it. also when I use the arrow down key to move a control onto the tab control page, it does not have a normal shadowed effect to indicate that it's a floating control.
The tab control is in the attachment.

Click on the control, then click on the Reorder button in the toolbar (should be the far right) then click Ungroup.

  • Are indicators updated on an inactive tab control page

    To decrease loop execution speed (increase acquisition speed) I have placed diagnostic displays on a seperate tab control page which is normally not the active page.  The thought is that speed will be increased as these displays would not be updated unless needed (screen I/O is normally time consumming).
    Is this a viable method?
    Roy

    It is not that those controls will not be updated, but the drawing of
    those controls on the screen that you save. This can definitely be very
    significant. It is also good programming praxis to hide unnecesary
    front panel elements.
    Also keep in mind that the eye can only handle 10-20 updates a second,
    and even that is for most controls much too fast. Lowering the
    indicator update rate to, say, 5-10 times a second, can  already
    achieve  major CPU relief. depending on the kind of interfacing I
    would go to much slower updates still.  If you use big data sets,
    you should also try to prevent creating too many copies in memory.

  • How do i set tab control page size programmatically?

    Hi,
    I have a tab control in my program and each page has different amounts of controls on it. I would like to know how I can make the tab control pages resize automatically, only to fit the controls on the page and not have extra space underneath that other pages require.

    You can use the tab control property 'PaneDimension' to
    programatically change the size of the tab control. To
    programatically find the areas occupied by the controls on each page:
    Use the 'Pages' property of the tab control to get a reference to the
    desired page; wire that to a property node and select the
    'ControlsOnPage[]' property; iterate through all the control
    refere
    nces, getting the position and bounds of each control, using
    'Max & Min' and shift registers to find the extent occupied by the
    controls.

  • Array of Tab Control page names

    Hi,
    I wish to programatically create an array of the names of the pages within a Tab Control.
    See the attached VI for my attempt at this.
    It works, but as it runs it changes which page is displayed on the front panel.
    Is there a way to do this without changing the page displayed on the front panel?
    Cheers,

  • Tab control page label change color programmatically

    Hi everybody!
    I have a question about a tab control.
    I'm trying to figure out a way to programmatically change the  properties of the tab labels so the selected tab's label looks different to the others.
    I'd like to do this by changing aspects of it's font and it's color. But I can't find out how to access it either directly or by reference.
    I can get at the label string so if all else fails I could make the selected one all capitals!
    Am I missing something, or is this one of those things which can't be done?
    I'm using Labview 11.
    Regards,
    Jonathan.

    The link still works for me!
    Search the forum for "Tab Color".
    This does not change the text, but the tab color which is what I do to high light the selected tab.
    I use dark gray and light gray to help the user tell which tab is "active".
    Not exactly what you wanted.

  • Tab control page name

    I’d like an example or description of this:
    For Tab Control, change the name of the Tab Page at Runtime?
    Thanks,Chris

    You CAN do this.  For each tab, right-click and choose Advanced->Make Page Caption Match Label to uncheck the option.
    Then, in your program, get the Pages property.  Use that reference to access the Caption property.
    Note that the enum strings do not change, so if the LABEL for the tab is Page 1 and the caption is hello world, the tab value is still Page 1.

  • Tab control page Setting problem?

    Why I am not able to change the page Label name programmatically. Why the page Label Name property is only readable?

    Hello.
    If using Labview 7, you must be able to change tab labels programmatically. There is an example called "tab control properties.vi" that shows how to do that.
    If using Labview 6 , this link has an example, too.

  • Change tab control page programatically using boolean.

    I am wondering if there is a way to programatically change the tabs on tab control when a user clicks a button on  the interface? Here is what I am trying to do and if anybody has any great ideas please let me know. I have a tab control with currently 3 tabs. I want a button on the main area of the vi to go to page 2 and back to page 1 as the user clicks it. The second is that I want about 5 buttons in page 2 that will go to say page 3-5. Any ideas. Thanks

    Sure, though I don't know why the user can't just click the tabs themselves. All you need is a simple event structure and writing to a local variable of the tab control.

  • Duplicate a Tab Control Page

    This there a way to progamically duplicate a page of a tab control.

    No, that would require duplicating not just the page but also duplicating all the controls and indicators on that page--which LV can't do at runtime.
    No problem though, there's always a way to get where you're wanting to go. What exactly is it that you need to do?

  • Pass data between Tab Control Pages

    I’d like to initiate a serial VISA session in the first page of a Tab Control to use the VISA Serial Configure.VI outputs (Visa resource name and Error cluster) in other pages or outside the tab control.
    So, how can I pass those references outside the page? I used local variables, but it doesn't seem the best way to do this because I need to create several variables to capture the reference in each page of the tab control...
    I created a sub-VI to initialize the VISA session, but in this case it always starts a new session every time I use the sub-VI….
    Thanks in advance!

    There's no reason at all to wire the tab control to a case statement. Since you have the read and write Booleans and they can't be clicked until the user changes tab pages, no code for the tab is necessary.With the Booleans for write and read, you should just have an event structure for those. You could initialize the serial port outside the main while loop and just pass the resource name in. Of course, if you wanted a tab for the init funciton, you could do that to but put a Boolean on that page to execute it. The only time you need to wire the tab control to a case statement is if you want to run some code immediately when the page is clicked.

  • Cannot drag and drop library items to master page

    I'm using Windows 8 and just downloaded Muse. In following along the tutorial (https://helpx.adobe.com/use/how-to/create-website.html) the instructor has us download some graphics. One is a library item, which opens fine in the panel, but I cannot complete the action the instructor does, which is to grab the color swatches from the library panel and place them on the main template. Any ideas?

  • 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,

    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.

  • 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.
