= triggerEvent =

== Syntax ==

:int triggerEvent(int n, int event, int previous)

== Arguments ==


::the control number of the event (eg CTL_OK or a programmer defined value)


::the type of event to raise (eg FME_CLICKED, FME_CUSTOMEVENT)


::a value to pass to the event handler (usually the previous value of the control)

== Return ==

:A value of 0 or 1, depending on whether the event handler code returned true or false.

== Description ==

:triggerEvent is used to artificially launch events, such as a dialog button click, the mouse moving over a dialog control, or to trigger timer events without resetting the actual timer. You can also use triggerEvent to write your own user-defined functions. By using FME_CUSTOMEVENT and creating custom values for the 'n' parameter, you can call specific sections of your OnCtl handler. You can even use the previous variable as a simple function parameter - though if you need more parameters, you are better off using the built-in global variables to pass and return values.

== Example ==


OnCtl( n ):




switch ( n )


case 0:

// Execute this code

if ( previous == 1 ) ...

else if ( previous == 2 ) ...

return true;

case 1:

// Execute that code


return false;



return false;

== Comments ==

:Everyone can add his comments about his experiences with this function here. Tips for using it are welcome, too.
