Creating a Flex AIR text editor: Part 29

In this tutorial we will add icon buttons to the tool bar of our application.

This is what we'll have by the end of this tutorial:



Firstly, we will turn our toolBar Box component into an HBox with a fixed height and padding values:

<mx:HBox id="toolBar" width="100%" backgroundColor="#dddddd" height="30" visible="{pref_toolbar}" paddingTop="2" paddingLeft="3">

</mx:HBox>

We are going to create buttons with icons in them now. All of the icons that are use are from the Silk icon set from FamFamFam, and they're 16x16. My buttons are going to be 20x20, so that I can display a transparent square around the icon when the user rolls it over.

To create the buttons, I need to create a new class for my button - IconButton.

Create a new document IconButton.mxml, use it to create the 'icon' property using metadata tags. In the root Button tags, set the skinClass property to skinIcon:

<?xml version="1.0" encoding="utf-8"?>
<s:Button xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" skinClass="iconSkin">

<fx:Metadata>
[Style(name="icon",type="*")]
</fx:Metadata>

</s:Button>

The iconSkin class is a separate document, create it - iconSkin.mxml. Here we need to first set the states for the button, then use the Metadata tags to set the HostComponent to the Button component (because this is a button skin) and draw whatever graphics you want. For me its a transparent on roll over square.

Add a BitmapImage or an Image object to hold the icon - set its source to hostComponent.getStyle('icon') and set its position too:

<?xml version="1.0" encoding="utf-8"?>
<s:SparkSkin name="iconSkin"
        xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark" 
        minWidth="21" minHeight="21"
        alpha.disabled="0.5">

    <s:states>
        <s:State name="up" />
        <s:State name="over" />
        <s:State name="down" />
        <s:State name="disabled" />
    </s:states>
 
    <fx:Metadata>
        [HostComponent("spark.components.Button")]
    </fx:Metadata>
 
    <s:Rect width="24" height="24" alpha.up="0" alpha.over="0.8" alpha.disabled="0">
<s:stroke>
<s:SolidColorStroke color="#666666"/>
</s:stroke>
<s:fill>
<s:SolidColor color="#ffffff"/>
</s:fill>
</s:Rect>
<s:BitmapImage source="{hostComponent.getStyle('icon')}" top="4" right="4" left="4" bottom="4" />
 
</s:SparkSkin>

Now that this is ready, we can populate our toolbar with icon buttons! Set each object's icon property to the url of the icon graphic, and toolTip to whatever the button represents. Also, for buttons like New, Cut, Copy and Paste we can already set the click property to the functions we already have:

<mx:HBox id="toolBar" width="100%" backgroundColor="#dddddd" height="30" visible="{pref_toolbar}" paddingTop="2" paddingLeft="3">
<custom:IconButton icon="@Embed('../lib/page.png')" toolTip="New document" click="doNew();" />
<custom:IconButton icon="@Embed('../lib/folder_page.png')" toolTip="Open" />
<custom:IconButton icon="@Embed('../lib/disk.png')" toolTip="Save" />
<custom:IconButton icon="@Embed('../lib/disk_multiple.png')" toolTip="Save all" />
<custom:IconButton icon="@Embed('../lib/printer.png')" toolTip="Print" />
<s:Label text="|" fontSize="18" color="#bbbbbb" paddingTop="4" />
<custom:IconButton icon="@Embed('../lib/arrow_undo.png')" toolTip="Undo" />
<custom:IconButton icon="@Embed('../lib/arrow_redo.png')" toolTip="Redo" />
<s:Label text="|" fontSize="18" color="#bbbbbb" paddingTop="4" />
<custom:IconButton icon="@Embed('../lib/cut.png')" toolTip="Cut" click="doCut();" />
<custom:IconButton icon="@Embed('../lib/page_white_copy.png')" toolTip="Copy" click="doCopy();" />
<custom:IconButton icon="@Embed('../lib/paste_plain.png')" toolTip="Paste" click="doPaste();" />
</mx:HBox>

Full main mxml file code:

<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
                       xmlns:s="library://ns.adobe.com/flex/spark"
                       xmlns:mx="library://ns.adobe.com/flex/mx"
   xmlns:custom="*"
   creationComplete="init();" title="Kirpad" showStatusBar="{pref_status}"
   minWidth="400" minHeight="200" height="700" width="900">
