Re: Worker and UI

Peter: I’ve been using Call worker to display a large ALP Area - 3k to 30k rows and 115 columns. The UI supports a palette that communicates with all of the windows and the windows communicate with each other so that when a value is changed in one window, Call form is used to initiate the update

Re: Worker and UI

I’ve used Call worker with the dialog command. Call worker seems to be "yet another way" to open a process but it doesn’t return a process ID. Similar to New process, you can name the process and pass parameters. If you’re closing the dialog and want the process to terminate, just call Kill worker

Re: Display entity selection time fields in a list box?

No, that is a compatibility setting for older 4D versions where time values were converted to milliseconds instead of seconds. Hoping some day there will be an option to just use time values instead of numbers. That was done for dates (instead of strings), seems like it should be possible for

Re: Worker and UI

I don't see why it would not work. I'm not aware of any real difference between a worker and a regular 4D process except that a worker has queue of requests and lives until killed whereas a regular process executes one request and exists. I tend to use the 4D progress component with some

Display entity selection time fields in a list box?

I'm replacing some record based list boxes with entity selection list boxes. I want to see HH MM SS format which was easy and the default with selection list boxes. But since ORDA treats time as a number, the only way I see to do that is to wrap the field property path with the Time function,

Worker and UI

v18.1, Mac What can a worker process do by way of UI? Are there any restrictions? Situation: I have a task which takes a while to set up but which, once set up, runs swiftly, perhaps quite often. At present, I just wait for the setup to complete, but while it’s only a few seconds, it’s boring.

Re: Text Editor Which Knows 4D Tags?

just so you know, language-4dm is for 4D method code (project mode, or METHOD GET CODE with tokens). it is a "tree-sitter" parser, a relatively new type of syntax highlighting. language-4dtag is for 4D code embedded in XML or HTML. this one is a regular type of parser. (regex based). ---

Re: v17.4 and UUIDs

not 100% sure, but maybe the duplicates are actually nulls. if you display the UUID fields in a list form, and resize the window, do the values change? if yes, what you see are phantom UUIDs, there are actually null. I assume you added auto-generating UUIDs, I assume you did this in a v17.4

Re: v17.4 and UUIDs

It is not my code. It is 4D that fills in the UUIDs in this circumstance. The question is why does 4D fill in some but not all UUIDs Chuck Chuck Miller Voice: (617) 739-0306 Informed Solutions,
