    [CLOSED] FontFamily style in ComboBox

    Hi,

    We are trying to build a ComboBox for a font family selection. Is it possible to show each item in the combo with their own font-family style?

    More or less, something like this:

    <ext:ComboBox runat="server" Width="120" Editable="false" ColSpan="5">
        <Items>
            <ext:ListItem Text="Arial" />
            <ext:ListItem Text="Courier New" />
            <ext:ListItem Text="Verdana" />
        </Items>
        <SelectedItems>
            <ext:ListItem Index="0" />
        </SelectedItems>
        <Listeners>
            <AfterRender Handler="item.getEl().dom.style.fontFamily = this.value;" />
            <Change Handler="changeFontFamily(this.value);" />
        </Listeners>
    </ext:ComboBox>
    Thanks in advance.

    Thanks,

    It works well unless the first time, when "combo.inputEl" is undefined. I will check for it in my code.

    Please replace
    <script type="text/javascript">
        var onChange = function (combo, newValue, oldValue) {
            combo.inputEl.applyStyles({
                "font-family": newValue
            });
        };
    </script>
    with
    <script type="text/javascript">
        var onChange = function (combo, newValue, oldValue) {
            if (combo.inputEl) {
                setFont(combo, newValue);    
            } else {
                combo.on("afterrender", function () {
                    setFont(combo, newValue);
                });
            }
        };
    
        var setFont = function (combo, font) {
            combo.inputEl.applyStyles({
                "font-family": font
            });
        };
    </script>

    Thank you very much, again.
