1.12.3 BLOX.BDropDown: flexibility

createList

Create the popup widget to be used for the ‘drop-down list’. It is a BList by default, but you can use any other widget, overriding the ‘list box accessing’ methods if necessary.

createTextWidget

Create the widget that will hold the string chosen from the list box and answer it. The widget must be a child of ‘self primitive’.

itemHeight

Answer the height of an item in the drop-down list. The default implementation assumes that the receiver understands #font, but you can modify it if you want.

listCallback

Called when an item of the listbox is highlighted. Do nothing by default

listSelectAt: aPoint

Select the item lying at the given position in the list box. The default implementation assumes that list is a BList, but you can modify it if you want.

listText

Answer the text currently chosen in the list box. The default implementation assumes that list is a BList, but you can modify it if you want.

text

Answer the text that the user has picked from the widget and/or typed in the control (the exact way the text is entered will be established by subclasses, since this is an abstract method).

text: aString

Set the text widget to aString
