Bug? Button Appearance is changed with hidden boolean text

I encountered the following problem with customized buttons:
I created a button,  made label, caption an boolean text invisible, then added a picture to decal and resized the button to fit to the picture. This means, i had to decrease the width. Everyting works fine on my development machine. There is installed LV2012f3 on Win7 x64.
When I open the VI or the created EXE on my Laptop, the Button changes in size and position. There is the same LV Version installed on WinXP 32bit.
This problem occurred with only two of several buttons. The other buttons didn't show this behaviour.
The pictures below illustrate this problem.
Now I found out, that the hidden boolean text was the reason for this behaviour. Because at these two buttons the boolean text is wider than the actual width of the button, LabVIEW resizes the button when opening in a different runtime environment(?)
So the workaround is, to delete the unneeded boolean text.

I think the logic behind this behavior is that while the text is hidden, you could show it programatically and presumably you wouldn't want the button size to change at that point, so the text is taken into account even if it's hidden.
Of course, you could also change the font size at run-time, which would also change the control size, so it could be argued that the control should only grow when you show the text.
Either way, I don't think this is so much a bug as it is unexpected behavior. The argument for how it should actually behave could go either way.

  • Array of buttons with different boolean text ?

    I'm looking for a method of displaying a 2D button matrix with
    different boolean text on each button. It seems an array of booleans
    must all have the same text. Perhaps a cluster could be used, but the
    array makes button alignment easy and easy to determine which had been
    pressed (radiobutton style with only one button true at a time).

    When might that Latched When Pressed behavior be useful ? Using a 2D
    array of buttons (not cluster), in LV 6.1, a Value Changed event for
    the array can be used as you mention below to XOR the event's OldValue
    and NewValue and wire that to a local variable copy of the array.
    This easily gives a radio button effect for the entire 2D button
    matrix. The array control automatcially arranges the visual
    alignment of the buttons.
    For the cluster method, I'd like to programmatically change which
    button is true. All the approaches I come up with end up using
    Array-to-Cluster which then requires the cluster size to be specified.
    I may end up wanting to programmatically vary the number of buttons in
    both dimensions and hence the cluster size. LV's Align Objects and
    Distribue Objects ends up making the button visual alignment not
    difficult (for a 12 x 8 matrix).

  • How to make mouseover scroll buttons attached to textarea with external loaded text ?

    Hi,
    I am working in Flash CS3 and AS3, and I'm not good in
    scripting.
    I want to make a dynamic textarea with loaded text from an
    external textfile, and then I want custom made arrow buttons to
    start scrolling the loaded text on mouseover (not click) andt stop
    scrolling on mouseout. Ala like in this webpage:
    http://boomjinx.com/
    The part with the loaded text is fine, but I can't manage to
    script the arrow buttons to do what I've just described. Even
    though I have searched the Internet for recipes I just find how to
    scroll loaded text on click or with a scrollbar. This problem is
    starting to drive me crazy!! Is there anyone that have a recipe for
    this??

    Here's one approach:
    First you need to create a dynamic mutline textfield that has
    autoSize properties set to handle a varying amount of text.
    Then you need to embed the font because you are going to use
    a mask over the textfield to define the viewable area of it.
    Then you will use the buttons to change the textfield's y
    property to move the textfield up/down vertically. You will
    probably need to use an ENTER_FRAME event handler so that a
    continuous hovering of a button will cause the textfield to
    continue moving until it either reaches one end or the other or
    when the hovering ends.
    Before you try to tackle that though, just make it so that
    hovering a button will cause the textfield to move up or down one
    increment of distance. Just take it one step at a time.

  • How to change gtk theme dialog box button appearance when using tab?

    Hi,
    I'm using candido as my gtk theme and have noticed that when a dialog box pops up (Yes / No), it is extremely difficult to tell which option is highlighted. How do I change this appearance? I searched through the gtkrc and even used gimp to manipulate the images used via trial and error to see if I found one that worked. Can someone familiar with gtk themes tell me which gtkrc or image to alter to affect this appearance?
    I use tab to select my option a ton and hate not being able to tell what I'm looking at.
    For reference,
    - here is the current look (can you tell which one is highlighted? It's "Cancel" -- just slightly bigger or a fine line around it) LINK
    - here is the gtkrc if that helps? LINK
    For one more point of clarification, I'm not talking about the button appearance on mouseover. I have identified that the button-prelight.png file changes that. I specifically am talking purely about a dialog popping up and then using the tab key alone to highlight through the options. I really like this theme, but this one thing drives me crazy. This appearance changes when I select different themes with lxappearance, so I've narrowed it down to being a gtk-theme issue, not my openbox theme or icon set.
    Many thanks!

    HI,
    Debug the program after you press the CANCEL button , you will get where the conrol is flowing , And instead of using
    Leave to screen '910'          use               Leave to screen 0.

  • Bug: "Paste Special: Value" overwrites data hidden with Table filters

    I've noticed the following....
    Create a sheet with the values below and enable the "Filter" option on this table.
    (I've added the row-numbers on the left, to later show the filter in action)
    (1) col1
    col2
    (2) a 1
    (3) a 2
    (4) a 3
    Using the filter option on the col2 column, unmark value "2".
    This is an essential step, since the bug only appears when hiding rows -in between- of other rows.
    Hiding 1 or 3 will not have the same result.
    You table should now look like this. Notice row (3) is hidden, as it should be:
    (1) col1
    col2
    (2) a 1
    (4) a 3
    Now type "b" in a random empty cell, select the cell (not the value), and copy it.
    Now, and this is an essential step, click down on the "a" value on row (2), keeping your mouse pressed, drag to the "a" value on row (4),  so that both cells are selected with one selection box, not two separate boxes.
    Within this selection box, right-mouse click, and select "Paste Special -> Values" NOT "Paste Special -> Paste".
    Now use the filter to unhide value "2". You table should/will look like this:
    (1) col1
    col2
    (2) b 1
    (3) b 2
    (4) b 3
    This is -not- the expected behavious, when using "Paste Special -> Paste", the result is
    as expected:
    (1) col1 col2
    (2) b 1
    (3) a 2
    (4) b 3
    This issue is also present in Excel 2010, and i've tested this on various computers.

    Tested in Excel 2013, it also happens there.

  • Run time change # of radio button and boolean text

    does Labview 8 support run time programmically change number of radio button and boolean text for each radio button?
    Thanks,
    DG

    You can also customize a slide control to look like radio buttons. You can control the text labels and the number of element through a property (by changing the scale properties). If you really want it to look like radio buttons, you can try ripping the images from the dialog radio button. Also, to save some time, you can get the OpenG buttons package, which includes a slide customized to look like radio buttons. The main problem with this is that changing the number of items does not change the size of the control and that makes the dot filling the radio buttons look compressed.
    Another option is to create an array of radio buttons, but then you will have to handle the logic yourself.

  • Creating a button that changes with the images in a slideshow in Adobe Muse?

    Are you able to create a new button inside or outside of a slide show that changes with the images?  I want to have the images change and contain a title and link to the project they are related to.  Whenever the image changes, whether automatically or someone clicks the "Next/Previous" buttons, the button link and title will change with it.

    Sorry,  not sure exactly how to describe it.  I have a link to a page that uses this technique:
    www.roofstudio.tv
    The first page ("Featured" page) contains the what I am looking for.   The title of the project changes with picture but the link on the "view  project" button (probably just a new button in the same location) also changes.   So when the picture of project X is up the button will take you to project X's page.  When it changes to the project Y picture, the link will take you to project Y's page.  My problem is that I'm not sure how have my button or even the text to change.   Slideshows only change pictures not buttons.   Since it's a widget i can't seem to add any new buttons.  Hope this is a better description of my issue.

    Hello, Miryam Maria. 
    Thank you for visiting Apple Support Communities. 
    I see you are experiencing issues with sound on applications when playing video/audio content.  If this is the case, the first thing I would check is if the side switch is set to silent as this can cause applications to be mute.  Below I have included an article that covers adjusting the  settings for the side switch.  Also, make sure to close all applications in Multitasking and power cycle the device.  Test the sound issue after processing these steps.

  • My magic trackpad fell yestarday and the start button appeared blocked and now it does not work. Apple is not competent in giving a solution. Only replacement is possible paying a new one. They simply do not repair it. Anyone may help me with a solution?

    My magic trackpad fell yestarday and the switch button appeared blocked and it is not possible to make it working. I contacted Apple support and it is not competent in giving a solution. They only suggest replacement and pay a new one. They simply do not repair it. It is a very poor solution since there would be other solutions. Anyone may help me with a solution?

    Hello folks!!!. I found out a solution. I simply take the start button off with a screwdriver and now the trackpad works properly. Since it initializes automatically when the computer turns on, the magic trackpad works without the need of using the start button. The only drawback is that there is a loss of aesthetic because the trackpad has now a gap, which was occupied by the button, but it is not easy to notice. It seems to be a better solution than that given by the apple customer service, which was to pay a new one.

  • How to fix the with of buttons when boolean text is too wide

    I need to change the boolean text of boolean. But the size of buttons is increasing when the text is too wide.
    I have created a SubVI to avoid that. But it is taking some time to compute...
    If anyone has a better idea...
    The reason why I need that is becase I don't have control of what the user will put in the button.
    See the example attached.

    Right-Click on the Booleans and select "release text". This will decouple the size of the boolean from the size of the text.
