I've tried to use the WOPopUpButton. I need to know how to select
an item of this list in order to call upon an action following this
selection (choice). What are the steps to follow in .WO and .java.
Thank you.
YourPopUpButton: WOPopUpButton {
list = theList; /* [1] */
selection = selectedItem; /* [2] */
noSelectionString = "-- choose one --";
displayString = anItem.name; /* [3] */
item = anItem; /* [4] */
}
[1] path to the list of items to iterate relative to current
component. e.g., productsList || application.marketingChoices || ...
[2] this variable will be equal to one of theList items if a
selection was made. It should also have the previous selection (if
applicable). If set anItem == selectedItem at some point.
[3] if your list has items that aren't strings then use this to
determine what method to call on each item to get a string value to
display
[4] anItem is each item in the list as it is iterated.
So upon form submission you can determine the selection via
selectedItem. If you're wanting the form to be submitted upon user
selection then add an additional binding to the popup:
YourPopUpButton: WOPopUpButton {
<...>
onChange = "javascript:this.form.submit;" /* or whatever */
}
with regards,
