[Xerte] Combobox thing

[Dave Burnett]

Thanks for that Julian, always handy to know what's going on under the hood.

This seems to work:

dropdownrs.selected[0].sIndex = -1;

You can force any list item to the display top.
-1 seems to blank it without affecting the rest of the list.

Make the array yourself and set null as the first item? Here’s the dode from the engine: cbo = this.attachMovie("FComboBoxSymbol", "cbo"+this.levels, this.levels);                this["cbo"+this.levels]._x = x;                this["cbo"+this.levels]._y = y;                if (w != undefined) {                                cbo.setSize(w, h);                }                cbo.index = this.pages.length;                //set up items...                               if (items.indexOf('{') == 0) {                                var cboItems = expression(items.substr(1, items.length-2), engine).split('~');                } else {                                var cboItems = items.split('~');                }                //set up data...                 if (data != undefined) {                                if (data.indexOf('{') == 0) {                                                var dataItems = expression(data.substr(1, data.length-2), engine).split('~');                                } else {                                                var dataItems = data.split('~');                                }                }                for (var i = 0; i<cboItems.length; i++) {                                cbo.addItem(cboItems[i], dataItems[i]);                }                cbo.setStyleProperty("background", STYLES.statusBarColour);                cbo.setStyleProperty("selection", STYLES.titleBarColour);                cbo.setStyleProperty("textColor", STYLES.textUnselected);                cbo.setStyleProperty("textSelected", STYLES.textSelected);                cbo.setChangeHandler("onComboChange");                cbo.getItem = function() {                                return this.getSelectedItem().label;                };                cbo.getData = function() {                                return this.getSelectedItem().data;                };                cbo.tabIndex = getTabIndex();                cbo.onSetFocus = function() {                                speak("Options.

Any way to set the default entry to ''  ?

Say we have these items:
New York~Moscow~Tokyo~London

New York appears in the default position, as well as the first dropdown list item.
Can I get a blank box initially?

I tried dropdownrs.topLabel.label = '';
But that blanks the New York in the first list position as well.
