How do I re-size a front panel display so that it fits on a smaller monitor?

My labview front panel looks grate on my desktop, but if I send it to one of the user's laptops it's much smaller. Is there a way I can scale the hole GUI to make it bigger?

Hi Over_Nyquest,
You can try auto adjust
Thanks as kudos only

How to lock the size of front panel so that user can't see hidden objects?

For that you can lock the VI with a password

Hmmm, Thats a really good idea! a key thought for you:
Protect the user from himself! your exe should NEVER display the Front Panel of a non-running vi. That data can't be updated or renewed - it contains no information the user could possibly be interested in. Really, that's the mindset you need while refactoring the app! Some other RUNNING utility may need to display information simillar to that shown on the vi FP in question but "Dead Data" is about the worst thing you can give to a user. (I've had simillar "Face-Palm" moments - don't feel too bad)

How can i use the same front panel graph in more than one events in an event structure?

i want to display the signals from my sensorDAQ in a graph.but i have more than one event in the event structure to acquire the signal and display it in the graph.the first event is to acquire the threshold signals and its displayed in the graph as a feedback.after the first event is executed, i will call the second event,where the further signals are acuired and compared with the threshold signals from the event 1.my question is how can i use the same front panel control in more than two events in the event structure?please answer me i'm stuck.
Solved!
Go to Solution.

Hi,
I have attached here an example of doing the same using shift registers and local variables. Take a look. Shift register is always a better option than local variables.

How can I save an EXE front panel image to a file?

The methods to save a VI front panel image to a file don't work on executable applications. How can I save an EXE front panel image to a file? (LabVIEW 6.1)

Hi,
i wrote some vi that save FP to image and created exe and it works fine. How do you save FP to image in VI?
If you use VI server method "Get Panel Image" and use "Write JPG file" ( or BPM) it works fine.

How to synchronize presentation on the front panel to the start of a 75Hz monitor's retrace cycle?

How to synchronize front panel presentation with the start of a retrace cycle of a 75Hz Monitor, so when a bitmap is presented 100ms, its duration is indeed 100ms on the monitor?

Hi,
In the old days (late 90's), we used in port and out port to wait for
vertical retraces (or even horizontal retraces).
I searched the web (vertical retrace), and there seem to be lots of
infromation and tools, like
http://www.compuphase.com/vretrace.htm
It uses a simple routine:
mov dx, 3dah ; VGA input status register
vretrace_loop:
in al, dx
test al, 8 ; bit 3 set?
jz vretrace_loop ; no, continue waiting
But to get it working, you need a VxD. Good news is you can download it.
The also suggest you use WaitForVerticalBlank(), but dx could be hard to get
working under LabVIEW.
Please let us know how (and if) you got it working with LabVIEW!
Regards,
Wiebe.

Leaving the front panel displayed on a subpanel after stopping

I have a tab control.
Each tab control has a subpanel.
Each subpanel has a static vi reference attached to it for launching.
I would like the image of the front panel displayed in the subpanel after the program has finished running so that any information that was displayed is still present.
Is there a way to retain all the settings between run's?

When you say settings, do you mean controls? If so, you can right click on them and select Data Operations >> Make Current Value Default. That will keep the settings initialized how ever you set them up.
I believe you can use use the Get Front Panel Image VI Method node, similar to the way to run the VI. You can create one by right clicking on the VI reference wire and selecting Method for VI Class >> Front Panel >> Get Image.
I've attached a code snippet of the node. If you want you can just drag the file into your block diagram and it should turn into code.

How can I make sure the text size on front panel will be adjusted by itself from PC to PC?

In my VIs under VI Properties -- Window Size, I checked the two boxes:
--Maintain proportions of window for different monitor resolutions
--Scale all objects on front panel as the window resizes
It seems that it worked for everything on front panel except the pure text wording that I put there for instruction purpose. The size of those text stuff didn't get changed proportionally after my application was built and run on different machines so some of them got cut off and looked messy.
Does anyone know how to fix this problem?
Thanks very much!

Hi Andrew,
Thank you for looking at my problem!
Both my development system and test system are Window XP. The font size are all set to Normal. What other details do you need to know?
The text on front panel shows well on my development machine. But when the .exe runs on my test machine, the text size was not adjusted by itself so the text body got cut off.
I found a way to "fix" this problem: I had to drag the text box down and right so there is enough magin between the text body and the box on the right and at the bottom. I had to try it a few times until it finally shows well on my test machine. However, with those magins, it doesn't look nice on my development machine anymore. Also, I only tried on one test machine, if it looks good on one test machine, will it look good on all the other machines? Eventually my app is going to run on Window 7. I'll have to test that out and find out if it's still going to be a problem. Anyway, I don't feel this is the right way to do it. I hope someone knows what I'm talking about and have a soluction to it.
Thanks very much!

How do I automatically make new front panels and block diagrams a certain size and screen position, like able to fit on a 1024 x 768 screen?

I'm studying for the CLD and I notice that one of the requirements is this:
Develop block diagrams to fit a screen resolution of 1024 x 768.
When I create a new VI, its resolution is slightly too big: 1110 x 768.
When I create a subVI via the menu item Edit >> Create SubVI, it is way too small: 800 x 543.
For both methods of creating new VIs, I would like to specify both the screen position and window size. But if that is not possible in LabVIEW, I'd like a quick way to make this happen. I see some property nodes for VIs where I could write a subVI that could do this for the front panel, but that is awkward. And it does not apply to block diagrams.
Is there a clever way to do these things?

It doesn't mean the default size of the window. It means once your code is complete, your block diagram should be small enough that you can see all your code when its on a monitor of that resolution. Before you test, set your computer monitor resolution to 1024x768. Write your code. If all the code on your block diagram can be seen without scrolling, you will be fine. They won't measure this explicitly. They are basically just saying "you shouldn't have a huge block diagram."

Maximum Character size of Front Panel indicator in LabVIEW

Hi,
I have a simple question that I hope somebody can answer. Is there a maximum character size that can be displayed in a Front Panel indicator in LabVIEW? If so, what is it? I have a VI that is continuously reading a serial port and updating a front panel indicator, and I need to know how much text can be displayed before it either truncates or throws an error. This is for LabVIEW 2010 SP1.
Thank you,
J Korn

A quick Flatten to string shows how LabVIEW stores strings {size-data} Size is a U32 so 4294967295 characters max.
The big thing to remember is this memory must be contiguous (and the Indicator requires a COPY) so in practice the performance hit for constantly allocating larger and larger buffers for the data and available memory impose practical limits much lower than the 4294967295 Char maximum. Probably better to log the data to a file and maintain only the last x characters on the indicator and use the file to look a history data

How to pop up another VI front panel and run this in the main VI?

Hi all,
I want to create a VI, which contain several buttons: like "RUN ANALYSIS 1" and "RUN ANALYSIS 2".
When I click one of them, another front panel of VI jump out and run automatically. When I click on "Finish" button on this VI (the one jump out), this front panel close.
How to complete it?
Thanks,

Hi Osso,
The ability to click on other VIs is also controlled by the Window Appearance. If you follow Dennis' instructions above, but this time change the Window Behavior to modal. You can find more information about the different selections in the LabVIEW Help: Customize Window Appearance Dialog Box.

How can I close a remote front panel by closing only the browser window?

I control a remote front panel in a browser (from the client PC). If I don't use the 'close' - button in my program to end the remote front panel, but instead of this the 'x' of the browser window (in the right bottom corner), my program won't be close, it continues on the server. Do you know how to end a VI by closing only the browser windows?
Thanks for any help!
wolfe

I found the examples. Thanks.
But I could not find a solution yet. Now I know how to end a VI by clicking on the x of the VIwindow.
My problem is, to end a VI by clicking on the x of the BROWSER window after I loaded and controlled a remote panel VI in a browser (e.g. IE).
If you have any ideas ... I'd be happy.
Thanks for your help.

Q:How to trim a VI's front panel at runtime?

The occupied front panel space can be obtained by calling
"GetPanelImage" via an invoke node. The resulting cluster "bounds"
describes the union of all front panel objects. The front panel can then
be resized to fit these bounds. The content of the front panel can be
repositioned by manipulating "FrontPanelWindow.Origin". This "...Origin"
points with an _unknown_ _offset_ (which varies with the FP´s layout) to
the upper left corner of the front panel content.
How to exactly calculate the origin from other front panel values?
Thanks,
TC

You can use a VI Server to position the front panel of your subVI. Look at the Ghost in the Machine.vi example that ships with LabView.
To see where to position the subVI, you need to know the position of the calling VI or of something on it. You could use a property node of the Get Details button.
1. On the front panel on Panel.vi, right-click on Get Details and select Create >> Property Node
2. Right-click on the Property Node and select Properties >> Position >> Left.
3. Point to the bottom edge of the property node and pull it down to add another element. That element should default to Top.
That will give you the coordinates of the Get Details button. Now use a VI server (based on Ghost in the Machine.vi) to place the subVI front panel the desired distance
from the Get Details button.

How to save settings in the front panel to different files and retrieve it later?

How to save the front-panel controllers' settings to different files and retrieve it later?
What I've archived is the "Save Settings" function, but when trying to "Reload Settings", I can only retrieve the saved data to front-panel indicators, but not the controllers!
Can anybody give me some advises?
Thanks in advanced!
Charles Lu

Hi
Just write the retrieved data to a local variable (but make it writable first) or property node of the controls.
Hope this helps.

How to set the size of my panels?

I have 4 JPanels inside of a JFrame.
I am using a GridLayout with 1 column and 4 lines.
My problem is that all panels have the same size.
I want to modify the size of each panel as I want.
How can I do that?

How to make some part of front panel transparent?

There is a property node to make a front panel completly transparent...but is there anything that only makes some part of the vi transparent like if I define a decorative block in the vi which takes 1 quardant of front panel and I have a control to make it transparent during runtime...
And moreover the frontpanel transparent property makes the whole window transparent, is there any way to retain toolbar of window like stop, run button when front panel is transparent??

Hi,
Have a look at this VI (attached). To make it work you need to create an image mask as a .png (open paint, colour in the areas that you want to become invisible and save it as a .png). The VI diffentiates between white areas and black areas of the mask you create, the black areas will become transparent and the white areas will remain the same- this will be implemented on your front panel. I've included an example of a possible paint image in "mask2.png".
You may also want to play around with the resolution of the mask created in paint, this will effect how the program works (I advise you use a lower resolution than your display- I used 500x300)
NT: If the front panel controls disappear, go into the block diagram window and attach a false constant instead of a control. Let me know if this works
Cheers, Tom
