hiding LEDs during runtime

[srini]

Does anyone know how to hide some of the LEDs or buttons on the front panel based on some conditions. Actually I am developing an user interface which will display the status of some digital lines and these lines are not fixed. They will vary with the project. So, I want to read the no:of lines from a file and display only those LEDs on the front panel .I want the rest of them to be either hidden or grayed out. How to do it?

You can put them in an array and crete a property node on it.

Chose the property "number of columns" or "number of rows" and set it to the value of the number of lines you want to show.

hi,
you can make use of the Property Node Property VISIABLE{TURE/FALSE},to hide things on runtime.

Right-Click on the "LED", choose "create -> Property Node". You'll get a
node on the diagram which is on "visible" by default. If you wire a
boolean "false" to this, it get's invisible, otherwise it's visible.

He forgot to mention he has 96 digital lines (see other questions by Srini today), so I am not sure it is the best way to do it ...

Using of 'property node' is the best option for this!!!

A tab control might be an option.

Hi,
Your option is good if I have to gray out(or make invisible) say 10 or 20 of the total lines. But in my case, the no:of LEDs do be grayed out are not in continous order and they may vary for different projects. In that case, I feel that using the property node for each LED is better. Any comments! I haven't used tab control till now. I will try that. But in case, when the application is opened, it should automatically read from a configuration fileand gray out the required LEDs. I don't know whether tab control can do it.
