Auto resizing path control

[Rashid-Malik]

How can I resize (programatically) so that the whole path is visible in a path control (for a file selected at run time)?
Thanks!

you can use a string indicaor/control instead to display the path, and create an invoke node called "size to text"

Hope this helps.

this is probably a very roundabout way of doing it, but they make it difficult on purpose, so you don't accidentally overlap your controls.

Hi rashid,

it seems you can't as the "bounds" property of a path control is read only (as for other controls too...).

The path indicator usually is fixed in size, also in other programs not written in LV...
The common work-around are:
- cut to filename
- use abbreviation (parts of the folder structure is presented as "/../../")
- use a scrollbar
- make the path control big enough

Hi Jeff,

how do you set the "Width" property to writable? Is this part of LV scripting? All my LV installations (ok, atleast LV7.1 and LV8.5) don't allow this feature...

[Rashid-Malik]

Dear Jeff! One question. The last width which one is it? size.width or something else?
Thanks a lot for the great answer.

You have to right click on the control and set the caption to visible (which I thought I eliminated by the first caption.visible step), otherwise labview doesn't create the caption for it, I guess.  And yes, the last one is Path Control.size.width.

This works in 8.2.1.  Also, it extends to the right.

edit - tst brought it to my attention that property nodes execute top to bottom, so you can combine the first three nodes.

Hi Jeff,

aahh it's the size and not the bounds...

Just a note: for me this method seems to get to small values for the width, I need some adjustments (~24 pixels?) probably due to path control border included in size property...

Happy Easter to you all!

I noticed something like that, but I wasn't sure if it was a font issue or a border issue, and I'm kind of swamped today so I couldn't monkey around and find out.

If you want to go the other way around, here's an XControl that truncates the path:
