I'm working on a Progress-4GL programming environment, based on AppBuilder release 11.6.
Until now I've been changing already existing *.w and *.p files, but now I wanted to created my *.w file from scratch.
I've created a window and I've put a browse, a fill-in field and a button. Now I would like to add an event to that button. In order to do that, I add following lines to the *.w file:
ON CHOOSE OF btn-Start_Query IN FRAME DEFAULT-FRAME
DO:
MESSAGE "button is pushed" VIEW-AS ALERT-BOX.
END.
However, when I save the *.w file, re-open it in the AppBuilder and save the file there again, those lines of code get removed.
I've already understood that, in order to avoid this, I need to "wrap" those lines of code by Scoped-define
or Analyze:suspend/resume
lines, something like this:
&Scoped-define SELF-NAME btn-Start_Query
&ANALYZE-SUSPEND _UIB-CODE-BLOCK _CONTROL btn-Start_Query C-Win
ON CHOOSE OF btn-Start_Query IN FRAME DEFAULT-FRAME
DO:
MESSAGE "button is pushed" VIEW-AS ALERT-BOX.
END.
&ANALYZE-RESUME
However, this seems not to be working.
Can you explain me what exactly I have to do in order avoid my lines of code to be removed?
By the way: I know that I'm working with extremely outdated technology, but I only work here for two weeks, so I don't have the authority to force my boss to change his development environment, just for me.
The recommended approach is to use the Wizards of the AppBuilder to create the trigger block with the required AppBuilder markup for you.
This will create an empty default trigger block (in case of a button, that's the CHOOSE). To create a different event, use the "New..." button in the section editor window.
