prevent double clicking action on mouse

[dphan128]

Hi,

How do I prevent the operator mistake of clicking more than once on a button and and causing the action to repeat again. I'm using event structure with "value change" event.

Thanks

You can disable the control in the value change event (using a property node), then enable it again after a timeout or after a process has completed, for example.

Thank you Altenbach. I tried what you recommended . But my program only work half of the time with that approach (inconsistent). Must be something else with my code that I need to sort it out on my own.

I was wonder if event structure can be set to accept the first click only and ignore any click after that.

You can programmatically filter out double clicks using Filter Events in the Event Structure. You can usually tell Filter Events by the "?" in their name. For instance, "Mouse Down?" is a filter event whereas "Mouse Down" is a notify event. There is a big difference between the two. Filter events allow you to change the event data before they get processed, whereas notify events happen after the processing occurs.

So you can actually register for a "Mouse Down?" event for your control and alter the Mods data that contains what type of mouse click gets registered. Specifically, you can set Double Click to false for your control. This will get processed before the Value Change event case.

What I said does technically remove the Double Click, but it doesn't keep two Value Changes from being recorded. You might try some form of the following, which does only register one value change for either a single click or a double click.

It is not clear if this is suitable for dphan128

Clicking more than once is "potentially" different to a double-click. We need more information on the application. 🙂

Agreed, more info would be helpful. Just guessing exactly how often the user should or shouldn't be able to click on a control is tricky to say the least. Perhaps a more passive aggressive approach would work for your average operator.

[dphan128]

I just want the first click to be acknowledged and any additional click after that will be ignored, until the process is completed executed and then ready for the new click again.

OK, that's not a "double-click" as defined by the OS. Use my suggestion. have you tried?

[dphan128]

Altenbach,

Yes, I have tried. But the result was not consistent as expected (see my earlier response).
