Hi Clifton,

I've been struggling with this for a couple of hours and have now found a workaround. But I wonder, should it be as complicated as this?

The problem: in a TB single-select box I use buildComboboxOptionsList to do just that. No problem, the list is created. However if the listbox has a click action, it no longer functions: the lines are not selectable. It seems pretty fussy. It won't even tolerate a variable being defined for the click event. I want the selected line to be put into a variable. I can do this if I use setComboboxOption in a click event in a separate button but this complicates the process for the user. My workaround is to use userProperty and mouseEvents and then use the mouseup event in the single-select box. But is this the best way?

To manipulate the comboBox or listBox, you must put your actions on the property change event for the comboBox or listBox.

Example:

To get the current item selected:




Actions for "on property change" event

When you run this example, a message box should pop up after selecting an option in the comboBox with the text of the chosen selection.

NOTE: Please realize that as soon as you use PowerPac functions to manipulate a comboBox or listBox, then some of the default behaviors do not work as expected. The reason for this is because ToolBook hardcodes comboBoxes and thus it does not understand the dynamic changes made to the HTML of the object. Therefore the parameter propertyName is always empty when using actions for on property change. To get information about a comboBox or listBox selection, always use setComboBoxOption() as it is entirely dynamic and more full-featured in that it can get mutliple selections and values assigned to selections. Also, the on select event is non-functional (or never gets sent) when a list is dynamically generated.

Hope this helps!
 

Many thanks once again.
