How to centre an image within tab control on front panel in LabVIEW 10 (Mac Version)?

Hello,
I would like to centre an image on the front panel. The image is on a tab control that is fit to the pane. I can't seem to find a way. I'm working with LabVIEW 10 on a Mac. Any suggestions would very much be appreciated.
Thanks,
Michelle

Thanks Gita_A. 
I have attached the relevant part of my program. It's not to do with the size but position of the image - I would like the image to be right in the centre of the tab control.

  • How to add external images onto a control and still be able to resize

    Hello,
    I'm a LabVIEW newbie.  I'm trying to customize the appearance of my VIs, and one of the things I like to do is to import external image and paste it onto the faceplate of the gauge indicator.  I've followed the instruction in the Labview application note using the control editor and was able to paste the picture into indicator.  But when I use it in the front panel and resize the gauge indicator, the image (added as a decoration) doesn't resize together with the indicator.  My questions are:
    1. How to add external images onto a control/indicator and still be able to resize the image automatically when I resize the control/indicator?
    2. How to "add" a new part to an existing control/indicator?  It looks like I can only customize/modify the existing parts of the control/indicator in the control editor. 
    Any help is appreciated.  Thanks.

    1/ Do not use the image as an added decoration. Instead replace part of the control with the image. Tis is illustrated in the attached vi : the arrow was pasted as a decoration, and also used to replace the slide cursor. Changing the control size do not affect the decoration, but changes the cursor.
    2/ What do you mean by adding new parts to a control. We have just seen that it was possible to modify a control. Now, if you want to include additionnal functionnality, that's another story. You can replace parts of the control, and this can give interesting results.  You can edit a slide control, and replace the numeric indicator by another control, including a numeric indicator, that you can replace with etc...
    But there, it still the same info displayed under different forms. If you want to have several independant functions on the same control, such as a string display and a boolean and a numeric indicator, then that's a job for a cluster...

  • How to show or hide a control in front panel

    Hi All, I am revising the code from someone else, and a control in front panel seems to be hidden until you click something to make it show. I tried to use right click in front panel and it did not work by clicking something related to show or hide. Since I don't quite familiar with property nodes, this hidden setting may be related to that.
    In the picture it shows the front panel and its two property nodes, could anyone advise me how to change the setting to show this control? Thank you!
    Solved!
    Go to Solution.

    If you right-click on the the control's terminal, you will see an option to "Hide Control" or "Show Control".  This is what you should use when editing the code.  The property nodes set to Visible are for when the application is running.

  • How to convert U32 value obtained from color control of front panel to float(SGL) for use with IMAQ Draw ?.

    I am trying to get user color inputs from front panel and use it in IMAQ Draw. I need to draw an oval of a certain color in a background of another color. Both these color values are user input. The problem is IMAQ Draw requires SGL color value and the color controls of front panel give U32. I have tried conversion VI's which hasn't worked. HELP !!!

    Jake,
    I think the color control can be wired directly to the input, but I am not positive. I don't know of any color conversions that would help.
    Make sure your image is a color image. You can't draw colors on a grayscale image.
    You might want to consider using overlays, which appear on top of the image but are not part of the image.

  • Identifying selected tabs within tab control

    I'm looking for a way to determine which tab is selected within the CVI tab control. The index is available, but the index isn't that helpful if the tabs aren't always in the same order. The Constant Name is used to identify controls on the tab page, but it doesn't look like there is a function to find the actual tab ID.
    I was thinking that a work-around is to programmatically add the panels to the tab control and track the IDs against the index in a table.
    The header file that is generated from the UIR only refers to the Constant Name as part of the #define associated with the controls.
    Any ideas ?

    It's true that you can use the label text and discover the active panel by means of a series of comparisons between strings, but it seems to me not the best way to go and surely not the fastest. The same consideration applies to ATTR_CONSTANT_NAME (the panel attributes which returns the text of the constant name, e.g. "MyPanel"). Moreover, this last solution leads to these additional critical points
    1. If you load a panel more than once, this approach doesn't give you a unique solution
    2. On the other side, supposing you can retrieve the value associated to the constant name, this value is unique only if all tab panel are defined in the same UIR file, otherwise their IDs could overlap
    In my opinion your solution of programmatically load panels and save panel handles in a array is the only possible way to go, since only panel handles are unique throughout the whole application.
    BTW, in the header file associated with the UIR panel constant names are listed too: in every group of #defines that refer to a panel and its controls, the very first is the panel constant name with its associated value (used in LoadPanel).

  • How to fit the images within textframe in indesign using javascript?

    Hi,
    We are using the update script for updating the values in table.
    If i am using images within textframe, the table is not fitting after updating it. Without using images the table is fitting.
    First i have dragged the table in Indesign document. Then i have altered the image size and updated the table using Update script.
    Finally i want to fit the table with the resized images.
    Note: I can get the updated values in table . but i cannot get the resized images.( Now i can get the original image after updating the table)
    Please help me if anyone has idea regarding this issue.
    Thanks,

    You'll need to use an event structure to respond to the mouse down, mouse
    move and mouse up events. In the mouse down event of the control, set a
    value in a shift register to true. In the mouse move event, when the value
    is true, change the position of the control with a position property node.
    In the mouse up event of the control, set the boolean in the shift register
    to false.
    &nbsp;second thing I want to ask if I want to make&nbsp;it copy
    paste,&nbsp;means main control will b at its initial position and where the
    mouse moves the image moves and when I leave the mouse&nbsp; the image gets

    You can't copy paste controls during run time. It seems you want to make a
    graphical application, where you can graphically drag and drop some
    configuration or something like that. You should have a look at the picture
    control. You can draw anything you want in this control, and catch mouse
    down, move and up events in the same way. It is perhaps a bit difficult to
    get to know it, but it is very powerful when you do.

  • How to make non-visibl​e Control on Front Panel Appear at Design Time?

    I have some Controls on the Front Panel whose visibility is changed (turned on or off) at Run Time. The problem is that if I stop the Run time, the Visibility of the Control remains in the runtime state in Design mode. So I may not be able to see or find the Control to make changes in Deisgn mode.
    How can I make all Controls on the Front Panel visible, or find and make visible a Control on the Front Panel whose Visibility has been made False?

I would mostly like to be able to display one image at a time and have the ability to programmatically change the image to different ones under program control. I found a picture indicator but not sure how to use if or if this is the best way. Thanks for any help.

    Yes, you can use a picture indicator.
    The attached simple codelet shows how to display a jpeg image on it (Make sure the image indicator is big enough).

  • How can I rotate waveform graphs or charts on front panel?

    I'd like to have my power spectrum graph displayed vertically on front panel. Any idea how to do it?
    Thanks for helps.

    THree quick ideas come to mind.
    1) Use XY graph and transpose X and Y.
    2) Use Picture control version of XY chart and hack away (these are included as example under chart and graphs)
    3) Graph to a "off-screen" indicator and periodicly use an invoke node to grab the image. There is an example on this web-site that will let you rotate an image and display it in a picture control.

  • Manually controlling the front panel without a keyboard

    Hi all,
    In my application I constantly switch the keyboard and the mouse between two computers (using a KVM switch), but would like to continuously be able to control a numeric control on the front panel of one of the computers (running LabView 6.1). Even if I wasn't switching, the use of the keyboard is awkward, since the control needs to be fairly effortless, quick and smooth. After searching a bit for a knob/wheel/dial type of controller, I was only able to find the new PowerMate (Griffin Technology) as a reasonable candidate, and have yet to purchase and try to integrate it. I'm also not sure how it will work with LabView.
    Am I overlooking a simple solution?
    Anyone have some experience with the Pow
    erMate?
    many thanks, Shy

    Another option: Create a simple TCP/IP application in VB or LabVIEW to
    control the control.
    That is,
    Monitor for incoming TCP/IP data in the VI with the control.
    If on your other computer you wish to make a change, just use your
    little application to do it, and send the value to the main app.
    Very cheap to do =)
    Another option 2:
    Grab the available Parallel Port digital interface design specifics for
    labview. Create yourself a simple binary switch interface. Assign 4
    bits for up and 4 bits for down.
    That is,
    sw1 = -10
    sw2 = -1
    sw3 = +1
    sw4 = +10
    Read in the digital input from the parallel port and increment your
    control accordingly. You can obviously assign any values you want to
    the digital inputs.
    Hope this helps guide you a little bit!
