Control Element- Specific Events
In addition to the preceding events, which are supported by all control elements, there are
also some control element-specific events that are only defined for certain control elements.
The most important of these events are:
When Item Changed
the value of a control element changes
Item Status Changed
the status of a control element changes
Text modified
the text of a control element changes
When initiating
an action that can be performed when the control element is triggered (for example, a
button is pressed)
When you work with events, note that some events, such as the When initiating event, can
be initiated each time you click the mouse on some control elements (for example, on radio
buttons). No action is performed to check if the status of the control element has actually
changed. To avoid such “blind events”, save the old control element value in a global
variable, and then check to see if the value has changed when an event is executing.
The When initiating event is also noteworthy for the following reasons:
• This event is initiated by either a key-press or a mouse button. Thus, it provides a
consistent interface for users who navigate by mouse or by keyboard.
• When the Repeat property of a command button is set to True, this event is the one
which is repeatedly sent, as long as the triggering action (key down or mouse-button
down) remains in effect.
The properties for the Item Status Changed event are:
Selected (long)
currently selected entry
Highlighted (long)
currently highlighted entry
ItemId (long)
ID of entry
