As you may already know, the Form event command identifies the type of form event that has just occurred. It’s typically used within a form or object method.
Some changes have been made in 4D v18, but it’s all good. Here’s what you need to know:
1 – Renaming the command
If (Form event=On Clicked)
When reopening your database, you’ll now see:
If (Form event code=On Clicked)
2 – Generic code is the way to go
Do you need to retrieve information about the current form event … using generic code? Just use the new FORM Event command in your form method! You can use the code attribute to get the event code, and the objectName attribute to find out which object triggered the event:
If (FORM event.code=On Clicked)
: (FORM Event.objectName="Save_button")
: (FORM Event.objectName="Add_button")
: (FORM Event.objectName="Remove_button")
3 – More information returned
For complex objects such as list boxes or 4D View Pro areas, you may need even more information. Therefore, the FORM Event command returns additional attributes just for these objects! For example, clicking on a cell in a 4D View Pro area will add information about the coordinates of the cell in the object returned by the FORM Event command.
