string control reset button (mac like)

[Sapiophile]

Hi all,

Has anybody ever created a string input control that has an 'X' at the right corner to reset the values in the control. If yes, how to do? I do have plenty of filters for my data in my application and it would be sweet to have similar input reset button as with the most aple applications.

Thank u 🙂

Hmm, an interesting idea.  Why couldn't you create a Cluster with two elements, String (a String, naturally) and Reset (a Latching Boolean).  I haven't tried making the appropriate Custom Control, but I can envision it ... .  I'm sure someone will give it a shot ... (maybe even I).

Hey, it works!  It was even easier than I thought it would be -- it's just a cluster, with some appropriate sizing and arranging the elements (Auto-sizing) horizontally.  I'm attaching the control -- feel free to play with it.

Depending upon how ambitious you feel, this would also make an interesting XControl.

Well I have to admit that I have like no clue of xcontrols. How would that work?

Have a look at this tutorial for XControls:

Creating New Front Panel Objects with LabVIEW XControls - National Instruments
https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000x2jVCAQ&l=en-US

It explains it pretty nicely. There is also a LabVIEW Example that you can use as a starting point.

Refer to the Simple Dual Mode Thermometer XControl project in the labview\examples\Controls and Indicators\XControls\Dual Mode Thermometer directory.

Hi all,

Thanks for your input. At the same time you recommended to so solve this task with xcontrols, I attended the lv adavnced architecture training and xcontrols are part of it. here's the solution:

Thank you all!

hi again,

the xcontrol I posted some time ago works like a charm, except the key focus. This seems to be an issue with any type of xcontrol that you cannot set the focus via the application anymore. I had the idea of a workaround to use methods, but I didn't got it to work. Any suggestions how to set the key focus of a xcontrol?

Thanks all!

[mikeporter]

What have you tried? I would be very surprised if the application key focus property worked. My expectation would be that it would give focus to the XControl as a whole, not controls within it.
