Mark,

I think you can indeed use a radio button and put the code lines you already worked out into a local method (local to the radio button).
You would indeed use the newValue that gets passed to the local method to control some if..else or case coding.
You won't get around acquiring some coding experience if you want to realize such stuff in applications, but it is worth the effort.

Cheers
Edgar

Hi Edgar,

Many thanks for the response.

As is typical, as soon as I posted the problem, I had a new idea how to achieve my desired result. Having tested this out, it seems to work.

Basically I created a new string variable called "filter_state" with a default value of "enabled".


I modified the methods I posted above to set a value for the "filter_state" string as seen below for the "disable_filters" method:

model.result("pg5").feature("surf1").feature("filt1").active(false);
model.result("pg3").feature("arws1").feature("filt1").active(false);
model.result("pg3").feature("surf1").feature("filt1").active(false);
filter_state = "disabled";

and below for the "enable_filters" method:

model.result("pg5").feature("surf1").feature("filt1").active(true);
model.result("pg3").feature("arws1").feature("filt1").active(true);
model.result("pg3").feature("surf1").feature("filt1").active(true);
filter_state = "enabled";

I then create a new method called "toggle_filters" as below:

if (filter_state.equals("enabled")) {
disable_filters();
}
else {
enable_filters();
}

I then created my button which simply invokes the "toggle_filters" method above. Right next to this button in the UI, I added an information card control which reads the string variable "filter_state" and displays some text and an icon that changes depending on the value of the "filter_state" string variable.

This pretty much achieves what I set out to and seems to work pretty well. The only thing is that the button itself does not change to reflect the "filter_state", but it is clear from the neighbouring info card what the state is. I will endeavour to develop the code such that the button image/text itself changes... just to satisfy my own pursuit of perfection!

Thanks again for your input...

Hi,

Just to add to this thread, for your information. From version 5.2, there is a Toggle button form object that you can use for this purpose. It can be connected to either a Boolean or a String declaration variable, which will be automatically toggled when the button is selected or deselected. For Strings, the variable will switch between the strings "on" and "off". Or you can use a Boolean variable with the values true and false.

Best regards,

Aaah... another reason to update to 5.2, will have to get our IT department to update my machine...

Thanks for the feedback!
