Autohandlers

The autohandlers offer improved inherit mechanism. That means they might just as well be used as normal libraries. If we want to write a generalized method that we could use in multiple .mql files it can be put in the appropriate autohandler file. One such example is the data/global_autohandler which is inherited in the data/autohandler file.

Autohandler files:

global_autohandler

GenericSelect_FIELD Method

The drop-down lists in the MasonSQL framework are implemented with select, htmlselect or divselect widgets, their implementation files are in the /opt/masonsql/htdocs/input/ directory.
All three widgets are wrapped around with GenericSelect_FIELD method from /opt/masonsql/htdocs/data/global_autohandler file. Its best to use the method with the _FIELD and _FIND_FIELD methods.

Here are parameters for the GenericSelect_FIELD method:

Parameter Name	Description	Default Value
widget	The type of widget is chosen with the widget parameter. Types of widgets are: 'select', 'htmlselect' or 'divselect'.	'select'
from	A .mql file name (without extension). The parameter determines from which table is the contents of the drop-down list.
buffer	A buffer name. The buffer parameter is specific to the default select method. It tells the method it should save the content of the table in a buffer so it doesn't need to be reloaded every time it is requested. The parameter is particularly useful with the TABLE form.	from
width	The parameter determines the width of the select field.	80
remote		Undefined.
readonly	If readonly is enabled and user clicks on the select element the alert pops ups saying 'Il campo non è modificabile'.	1
