Problem with cluster containing different objects !

Solved!
Go to solution

Hello 2 all !

 

Here is what i'm trying to do :

 

- i have a cluster of 3 elements : 2 boolean controls and 1 arrow.

- i want to  make every object in the cluster appear and dissapear in a sequential order like : boolean - invisible; arrow - invisible, boolean - visible; arrow-visible, boolean 2 -invisible and so on.

 

I've attached a vi in wich i've tried to deal with this issue but with no luck.

 

Any ideas ?

 

Thank you very much!

 

Andrew.

Hi Andrew,

use a property node to be able to connect the refnum to it.

Andrew,

 

Make the arrow a boolean control with a picture of an arrow.  Then all the controls are booleans and the visibility can be controlled by a simple loop.

As u can see in the original vi, i've already used property nodes but with no succes. (there was a type missmatch error).

 

Can u point out to me where was the mistake in the original vi ?

 

I ask this because i am still learning LabView and your opinion would be very useful 2 me.

 

Also a big  "thank you" to johnsold ! Smiley Wink

Your original VI doesn't work because you are wiring a control reference into an error cluster.  Because you are using Property nodes connected to the control, the reference is not needed.  You need to diconnect the property node from the control (right-click and choose "Disconnect from Control"

You can also use Link to... to select the control to which you want the property node to link.

 

To get a property node for the decoration is a little more involved.  One way to do it (there are usually several ways to do something in LV) is to drop a new property node from the Application Control palette.  Then Select Class >> VI Server >> Generic >> GObject >> Decoration >> Decoration.  Obvious to a beginner, right???

 

Here is another version of your program showing this method.

Thank you all 4 your time and interest !

 

Indeed the solution proposed by johnsold is very very simple . Smiley Happy

 

The first solution was also interesting...i didn't realyze that i could create a boolean control from a arrow.

 

Thank you 4 pointing this simple approach to me.

 

Guess i still have lots and lots to learn about LabView... but i must say it is a real treat !Smiley Wink

 

Excelent software ! Good work NI !
