Changing the control after creation
A control tag changes the properties of an existing control after it has been created. The
tag must be specified with the name of the control to be changed and the new properties.
It can be executed only within a form tag. The following properties can be changed:
● xpos
● ypos
● width
● height
● color_bk
● color_fg
● access level
● fieldtype
● itemdata
● min
● max
● default
The reference variable cannot be modified. If a property is to be changed by triggering by
a softkey event, the send message tag must transfer this request into the form context. The
message tag is used to acquire the message.
Example:
<menu name = "main">
<open_form name = "attrib_form" />
<softkey POSITION="3">
<caption>Set%nro</caption>
<send_message>1, 0</send_message>
</softkey>
<softkey POSITION="4">
<caption>Set%nrw</caption>
<send_message>2, 0</send_message>
</softkey>
</menu>
<form name="attrib_form">
<init>
<control name="c_p0" xpos="60" ypos="70" width="272" />
</init>
<message>
<switch>
<condition>$message_par1</condition>
<case value="1">
<control name="c_p0" fieldtype="readonly" />
</case>
<case value="2">
<control name="c_p0" fieldtype="edity" />
</case>
</switch>
</message>
</form>
