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 make non-visible 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?
THANKS.

This is documented in the LabVIEW Help.
Displaying Hidden Front Panel Objects
Complete the following steps to display a hidden front panel control or indicator. You also can hide front panel controls and indicators.
Find the block diagram terminal for the object. If you have several terminals with the same data type, right-click the terminals and select Visible Items»Label from the shortcut menu. Find the object with the label that matches the hidden front panel object.
Right-click the terminal and select Show Control from the shortcut menu if the object is a control or Show Indicator if the object is an indicator.
You also can use the Visible property to display controls and indicators programmatically.
You also can display all hidden front panel controls and indicators.

How do I get the Label for a Front Panel Control to appear in the Block Diagram but not on the Front Panel?

How do I get the Label for a Front Panel Control to appear in the Block Diagram but not on the Front Panel? On the Front Panel I am making a complex control that consists of a Slider and a Numerical Input box. Both Controls display the same information and either can be used for Input. When one changs, the other is made to display the same value.
But I only want the Slider to display the Label on the Front Panel, to avoid confusion. On the Block Diagram however, I want both controls to display their Labels so that I know what they are. How do I display the Label for a Control on the Block diagram, but not display its Label on the Front Panel?

No. The Label Visible property is separate for the front panel control label and the block diagram terminal label.
How did you start out with the block diagram's label not being visible? Whenever I drop a control or indicator, the label is always visible on both the FP and BD by default. Maybe there is a LabVIEW option that causes new controls/indicators not to have their labels visible by default, but I have yet to find it. I don't think an item should ever be dropped without the label visible, good LabVIEW coding practice demands that the labels for control terminals on the block diagram be visible so that you know what control or indicator a wire is going to.
That being said, I have seen a lot of VI's posted where the label for the terminal on the BD is not shown (against good programming practice.) I've gone to the BD and right clicked to show the label. Sometimes, the people have an empty label (which will turn off the visibility for both the FP and BD) and I'm forced to add some text of my own into the label so I can figure out what their code is doing. When I add some text to the label, at that time, I find both the BD and FP labels become visible.
Are you dealing with controls that have empty labels to start?
Good programming practices:
1. Always have a name for all of your controls, never use and empty label by deleting the text in the label.
2. Make the labels unique. For example, don't have two controls both called Stop. How do you know quickly know which terminal relates to which control?
3. Always show the labels on the block diagram, so you know the function of a control's terminal. If you want to hide the label on the FP, that's okay.
4. If you want a different label to appear on the FP than whatever you actually called the control, then use the caption. You can hide the label and show the caption. This is useful if you need to programmatically change what the "label" is on the front panel such if you are making an application that needs to change its user interface such as for a foreign language.

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.

How to show or Hide Generic Column in a regular report

Hi All,
I have created report based on "SQL query (pl/sql function body returning sql query). It returns columns based on some conditions. I have total 60 generic columns like (COL1,COL2....COL60) but it returns 18 or 20 columns based on my conditions, how can I hide the columns that I don't needed. My column heading is based on function return by ':' separated. My function returns number of columns also. Is there any we I can show only those columns which contains data. My report is exactly similar to the default "SQL query (pl/sql function body returning sql query). I didn't find any logic how they are doing this show and hide. I appreciate any ones help.
Thanks,

Hi there,
Somehow you need to find out how many columns your dynamic select will return (by what you said it seems that your procedure returns this information). Then store that number in a hidden page item, say Pnn_COUNT.
Then, for the 19th and 20th columns in the report add these conditions:
Column 19: :Pnn_COUNT >= 19
Column 20: :Pnn_COUNT >= 20
I hope this helps.

How to show or hide portlets dynamically on a Portal Page

Dear All
1. I have a Portal Page with One Portlet in the top having like 5 Buttons. Each button click should display a separate portlet in the bottom on this same page.
2. I have Top Portlet. For bottom I have 5 Portlets P1, P2, P3, P4 and P5. On my .portal file, I dragged and dropped top portlet and all these 5 Portlets one below each other.
3. Now, I am trying to use BackingFile approach at PageLevel/Portlet level, to get the details of button clicked in top portlet (like name etc), and then show only one portlet at a time in the bottom section (using portlet backingcontext show/hide APIs). I do need to compare the bottom portlets defintion_label etc. which is fine for now.
Is this the right approach...?
Or do I have to use Portlet Custom Event approach. So top portlet will trigger event everytime button is clicked with some payload. And bottom 5 portlets listen to that event and show/hide accordingly. But in this approach, I have to attach backingfile to all the bottom portlets to listen to them.
All the portlets are Pageflow based Portlets. Any ideas or any other simpler approaches, are highly appreciated.
Thanks
Ravi Jegga

Hi Kevin
1. Thanks a lot for the pointers. I will go with Events. So for bottom Portlets, I will use the same BackingFile. But still it is going to be custom Event. Because only one portlet will be shown. So its like my payload will be portlet def label. In Backing File, I will compare this payload with actual dynamic value and if same, show or hide that portlet. Please let me know if this is correct approach.
2. Now each one of the Bottom Portlets is a complex pageflow portlet with many buttons of their own. So everytime a button is clicked or action is invoked, the Backing File gets called. And I had to somehow know that the same portlet has to be shown or the show/hide logic should not be called. Is there any way, where backing file gets called or just listen for Events triggered only from main top portlet.
Thanks for the other message, where looks like you already gave lots of pointers. I will go through them.
I will design and test this out and will keep you posted with my results.
Thanks a lot again

How to move control in front panel at run time

       Hi,
                I'm using LabVIEW 8.5. I want to move the control anywhere in front panel. For example in the attach file I want to pick up the pict control (with the help of mouse) and drop it anywhere in front panel. second thing I want to ask if I want to make it copy paste, means main control will b at its initial position and where the mouse moves the image moves and when I leave the mouse the image gets drops there. How to do it. Please help me.

control anywhere in front panel. For example in the attach file I

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.

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 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,

How can I make an area of the front-panel have scroll bars?

I'm writing a VI that provides many options to the user. The front-panel is large and contains many controls ~130 of them, it's divided up visually to match the workings of the system the VI controls. One particular functional block has very many control options though these are rarely used. I can't fit all of the controls I need onto the screen area I have available.
What I would like is a way of making an area of the screen with scroll bars on it. I don't need any more than that, just an expansion of the front-panel area I have available. The "Sub-Panel" feature provides the scroll bars. But, a Sub-Panel is a way of accessing another VI, I don't want to do that. I could put the extra controls on the far-left or far-right of everything else and get the user to scroll the main scroll bars at the edges of the screen. The problem with that is that I it would mean couldn't lay out my front panel to match the system block-diagram as I have so far.
Does anyone know how to do this?
Solved!
Go to Solution.

I know I can show the scroll bars at the edge of the VI. In my case that's not very useful. The front panel shows a block diagram of a system. It's made up of a set of clusters which control various parts of the system. I want to keep this layout because it's very useful in explaining to people new to the system how it works. I inherited that approach from a previous iteration of the program for an older system. The problem I have is that the new system has far more control parameters for one of the blocks. Unfortunately it's one of the blocks in the middle of the block diagram. If it were one at the left, right, top or bottom it would be no problem because the main scrollbars could be used.
I can use a tab-control, that's my fall-back plan. The problem is that would be abusing the purpose of the tab control. In a tab control each tab is supposed to deal with a group of controls that have a common connection. So, all the things in tab #1 are supposed to be connected in some way and all the things in tab #2 are supposed to be connected in some way. There not supposed to be a way of gaining more screen space.
The controls I'm dealing with are numeric controls, switches and rings.

Urgent How to fulfill multiple lines input in CVI front panel?

Hi Guys,
I want to paste multiple lines text from other files to CVI front panel, but String, Text Box or List Box can't do when I tried.
Could some one tell me how I can realize it or show me an example?
Thanks in advance!

You can add this functionality by using RunPopupMenu to display your own menu when right-clicking on the control: see this discussion and the example attached to this post.

How to see the full program on the front panel when it is running?

Hi, my program is really big, and when I run it and obverserve the program on the front panel, I cannot drag the window to see the other parts. Also, I tried the method like hold control, then press + to zoom in or press - to zoom out. However, labview seems doesnt have this function. Does anyone know how I can see the full program then it is running, maybe zoom out or drag the windows? thanks!

You should use a Tab control. Group your front panel objects together and put the grouped items in tabs. Then you can select the Tab you want to display while the program is running.
It is never a good idea to make your screen too big to fit on one display. This goes for the block diagram also. If you have to scroll to see it all, use more subvi's. Make it modular. A state machine is a good way to put a lot of code on one display screen.

How do I center and/or maximize the front panel on every event?

Hi,
So basically I have a little issue with trying to maximize and then scale back a VI's front panel every time a user selects a different option from a ring control.
So far i've been using the LVWINUTIL.LLB and the provided window size vi to set the size I want on ring selection change which works fine, but as far as centering the VI goes, the method I'm calling only works the first time. After it maximizes and I select a different option on my ring control which is linked to a case within a while loop it simply resizes to the size i set which is correct but when I got back to the ring case which is supposed to maximize the front panel again, it doesn't do it. Centralizing the FP also only works once.
I'm using FP.Run-Time Position.Centered to try and center the VI....only works once. I do understand that this might be the desired behavior since the name is run-time position meaning it'll only do this when the VI is first run, however I need this to happen more then once, how can i do this? Thanks...

How did you center the FP?
Their a method that should work time after time.

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!
