View source is enabled in the following example.

You can also set the buttonHeight style in an external .CSS file or <mx:Style /> block, as seen in the following example:

    <mx:Style>
        ButtonBar {
            buttonHeight: 16;
            buttonStyleName: buttonBarButtonStyles;
        }

        .buttonBarButtonStyles {

        <mx:Object label="Blue"
                icon="@Embed('assets/bullet_blue.png')" />
    </mx:Array>

    <mx:ApplicationControlBar dock="true">
        <mx:Form styleName="plain">
            <mx:FormItem label="direction:">
                <mx:ComboBox id="comboBox"
                        dataProvider="[horizontal,vertical]" />
            </mx:FormItem>
        </mx:Form>
    </mx:ApplicationControlBar>

    <mx:ButtonBar id="buttonBar"
            dataProvider="{arr}"
            direction="{comboBox.selectedItem}" />

</mx:Application>

Or, you can set the buttonHeight style using ActionScript, as seen in the following example:

        }

        .buttonBarButtonStyles {
            textAlign: left;
        }
    </mx:Style>

            }

            private function comboBox_change(evt:ListEvent):void {
                buttonBar.direction = comboBox.selectedItem.toString();

                        value="24"
                        snapInterval="1"
                        tickInterval="2"
                        liveDragging="true"
                        change="slider_change(event);" />

            </mx:FormItem>
        </mx:Form>
    </mx:ApplicationControlBar>

    <mx:ButtonBar id="buttonBar"
            dataProvider="{arr}" />

</mx:Application>

Due to popular demand, here is the “same” example in a more ActionScript friendly format:

View source is enabled in the following example.

For simplicity sake, I only set the generic “skin” style which applies to all states (up, over, down, and disabled). You will also notice that we embedded a skin from a SWF file and the skins various scale grid settings (scaleGridTop, scaleGridBottom, scaleGridLeft, and scaleGridRight) are set in the FLA/SWF file and not in the MXML file itself. This allows you to resize the ButtonBar control without distorting the 2 pixel border on the bottom of the skin.
