Layout Events

<Field specification>: STRING

Pagecontrol.

OnClick

Event that is started when the end user clicks on the concerned fields.

<Field specification>: STRING

Checkbox, radiobutton group.

OnClose

Event that is started when a Closeform() is executed or when the end user chooses the AMT Screens menu option "Close" (or "Close all").

The CanClose parameter determines whether the form is closed or not. The default setting for this parameter is "TRUE", which means a close of the form. This parameter only has no effect when there is a SHOWPOPUP or GOTOFORM in the OnClose event handler. In that case, the form will not be closed.

On closing a form, eventual sendmessages, alerts or calls through a SHOWPOPUP or GOTOFORM instruction will be ignored. There is only one exception. A GOTOFORM that uses the option "BYE" will still be executed (meaning that the whole application will be closed).
