Events status

This command can set the frequency (1-10) or disable event checking (0). By temporarily disabling events you can speed critical processing. The default value is 1 which sets event checking on but less frequent.

The maximum setting is 10 which will cause event checking to occur very frequently. Note that a higher the setting is the slower your application is liekly to run.

status - This is a numeric value which is zero (0) to disable event processing or set from 1 to 10 to set event checking. Default = 1

This command sets a command key to call a Sub procedure or clears an existing definition.

char - This is a numeric value representing the ASCII code of the key used in conjunction with the Command key.

Sub - This is a reference to the a SUB procedure that will be called when the designated Command key is pressed. Use NONE to clear the Command key.

 

var = EventCode( code )

This function returns a numeric value that represents the event codes that caused a Sub procedure to be called. This is usually used in a Sub procedure that was called by MacStandardBasic in response to an event such as a mouse click in a contro1, window, or menu.

code - This argument should be a numeric value from 0 to 3 that indicates which event code parameter to be returned.
