Toolbarbutton

• Demonstration: Toolbar and Fileupload
• Java API: Toolbarbutton
• JavaScript API: Toolbarbutton
• Style Guide: Toolbarbutton

Employment/Purpose

The behavior of Toolbarbutton is similar to the button except the appearance is different. The button component uses HTML BUTTON tag, while the toolbarbutton component uses HTML DIV tag.

A toolbarbutton could be placed outside a toolbar. However toolbarbuttons change their appearance if they are placed inside a toolbar.

Toolbarbutton supports getHref(). If getHref() is not null, the onClick handler is ignored and this element is degenerated to HTML's A tag.

Within ZK 5, the file upload has been redesigned so it can be integrated with any widget. For example, the toolbarbutton can now be used to upload a file. In addition to this, the display of the upload status has been enhanced and can be customized easily.

        <toolbarbutton label="button6" image="/img/network.gif"

Toggle Mode

Toolbarbutton support toggle mode since ZK 6.0.0 . (mode="toggle" )

In the toggle mode , the toolbarbutton will be persistent checked after user clicked it, and will be released after next click. It will fire CheckEvent when state changed.

<window title="Toolbarbutton" border="normal" width="250px" >
	<toolbar >
		<toolbarbutton label="File system" mode="toggle" >
			<attribute name="onCheck"><![CDATA[
			    if(event.isChecked()){
					result.setValue("Activated:"+event.getTarget().getLabel());
			    }else{
			    	result.setValue("Deactivated:"+event.getTarget().getLabel());
			    }
			]]></attribute>			
		</toolbarbutton> 
	</toolbar>
	
	<label id="result" />
</window>

File Upload

Any toolbarbutton can be used to upload files. All you need to do is:

1. Specify the upload attribute with true
2. Handles the onUpload event.

<toolbarbutton upload="true" label="Fileupload" onUpload="myProcessUpload(event.getMedia())"/>

When the file is uploaded, an instance of UploadEvent is sent to the button. Then, the event listener can retrieve the uploaded content by examining the return value of UploadEvent.getMedia().
