Global Special Event Handlers
The global special event handlers implement specific global interpreter features.
They must be defined in the startup class as static methods to be taken into account.
Application_Read
Public Sub Application_Read()
Catches data sent to the standard input.
If that static method is defined in the project startup class,
then the standard input is watched by the interpreter, and the method is
called each time there is something to read on the standard input.
Application_KeyPress
Public Sub Application_KeyPress()
This handler is defined by GUI components. It intercepts every key press sent to the application.
If you stop the event, the key press will be ignored.
Application_Error
Public Sub Application_Error()
Since 3.5
This handler is called when an error is raised and is not handled by any
CATCH,
TRY or
FINALLY instruction.
Application_Log
Public Sub Application_Log(Text As String, Where As String)
Since 3.19
This handler intercepts each call to the
ERROR or
DEBUG instruction.
-
Text is the text printed by the entire instruction line.
-
Where is what
Debug prints before the text. It is void when the Error instruction is used.
If the standard error output is redirected by
ERROR TO,
Application_Log will not catch the printed text.
