Can't Resize Vertical Arrow Decoration

[Derek Price]

Using LV8.5.1, I'm unable to resize a vertical arrow decoration using the "Set Width and Height" layout tool.  Nothing happens when I select Apply Height. 



What am I missing?  Is this a bug?

Thanks,
Derek

I agree this looks like a bug. Once one of the dimensions is zero (horizontal or vertical), the resize dialog no longer works.

This is very frustrating when trying to draw multiple decorations and have them line up correctly.  Any ideas on a workaround?

Thanks,

The properties work, so you can try modifying the VI attached here and use that to change the size of all decorations.

I can think of two convenient ways to do this.

First, you can replace the existing dialog with your own VI. In your VI, you can test if the objects are decorations and if not, call the current VI. To do this, you will need to edit <LabVIEW>\resource\dialog\Resize.llb. If you do this, make sure to create a backup of the LLB so that you can revert to it if necessary.

The other option is to have this as a Tools menu option. You can see how to do this here. If you want a specific example, the Code Capture Tool is a nice one.

General comment on this issue.

Please correct me if I get this wrong.

Most of LV's graphics are 2-d are can be scribed by a top left corner and a bottom right corner. The exception to this statement are the line decorations. The difference between these two type can be seen when replacing a needle on a guage with one of the line decorations. They WILL rotate correctly. But if you replace the needle with a flat box decoration, the box will not rotate.

So in both case (line and rectangle) there are two points that define the object but how that definition is used differs.

I know this does not help with above problem but I hope it help sus understand a little bit more about the working of LV.

Again, correct me or enhace as you see fit.

Ben. Line decoration can easily be resized as long as they are not horizontal or vertical. Only once they are, things start to get weird.

Once they are horizontal or vertical, the length is no longer accepted and even if you change the width (which is now zero) back to a valid number, nothing happens.

Hi Derek,

I replicated this same problem and also searched through our corrective action request database for a previous bug report and wasn't able to find anything.  It does look like a bug, I'll create a corrective action request and see if we can find a work around for you.  Thanks.

Hi Stephen,

Thanks for the update!

Hi Stephen,

Do you have a CAR for this yet?

I have put in a corrective action request #116754 for this issue.  It actually affects all of the line decorations.  Thank you for your help gentlemen.  I should get more information after this request is processed through R&D but in the mean time, if you readjust the decoration with your mouse so that it is not verticle or horizontal, the dialog box will respond.  Of course, if you are doing this during runtime I realize that this isn't much of a work around.  Like I said, after the request has been processed with R&D we may be able to find a better work around.  Thanks.
