installing

out of the box the zk eclipse framework will use the Commerical version: Download the CE version

  • extract this to your apps folder
  • update zk eclipse to use this CE version

Note: the classes output of your project should be WEB-INF/classes

Installing in Mule Studio

For mule 3.4 (built on Eclipes 3.8) compatabile with 4.2 Add

Button Layouts

To align right and put space between buttons 

<div style="float:right;">
    <button id="Submit" label="Submit" />
    <space spacing="5px" orient="vertical" />
    <button id="apply" label="Apply" />
    <space spacing="5px" orient="vertical" />
    <button id="clearAll" label="Clear All" />
    <space spacing="5px" orient="vertical" />
    <button id="close" label="Close" />
</div>

Form Layout

To get a neat form layout, use grid with fixed columns http://www.zkoss.org/zkdemo/input/form_sample

Data Binding

Form level binding

apply="org.zkoss.bind.BindComposer"
        viewModel="@id('vm') @init('demo.input.form_sample.FormViewModel')"

Save only data binding annotations 

   <textbox value="@save(vm.person.firstname)"/>
   <textbox value="@save(vm.person.firstname) @save(vm.tmpperson.firstname)"/>
   <textbox value="@save(vm.person.firstname, before='update')"/>
   <textbox value="@save(vm.person.firstname, after='delete')"/>
   <textbox value="@save(vm.selected.firstname, before={'update','add'})"/>

Form Elements

Radio Buttons
<radiogroup id="evt">
  		<hbox width="100%" align="start">
				<label value="Migrate Messages"
					style="padding-left: 10px" />
			</hbox>
			<radio label="CmdMigrateDeal2" />
			<radio label="CmdMigrateTitleRights" />
			<radio label="CmdMigrateFinance" />

@Wire
  Radiogroup evt;
	@Wire
	Radiogroup migrate;

	private static final long serialVersionUID = 1L;

	@Listen("onClick=#Submit")
	public void doSaveProfile() {
		System.err.println("inside GetXmlController3  doing on click ");
		System.err.println("Got submit index: " + evt.getSelectedItem().getLabel() );
	}
TextArea's

some what confusing zk uses the same zk input field for texbox and text area.. the key differnces is adding the multiline="true" attribute

Message Boxes

Message boxes can be triggered from the controller without any client code required. 

Messagebox.show("Warning is pressed", "Warning", Messagebox.OK, Messagebox.EXCLAMATION);

Messagebox.show("Question is pressed. Are you sure?", "Question", Messagebox.OK | Messagebox.CANCEL, Messagebox.QUESTION);

Messagebox.show("Information is pressed", "Information", Messagebox.OK, Messagebox.INFORMATION);

BandBox

Injecting in Jquery

Zk supports jquery out of the box. For example if I wanted to modify a textarea wiht a custom attribute, add the following javsascript to the zul page:

<script>
zk.afterMount(function () {
    jq("textarea").attr("spellcheck", "false");
});
</script>

Timer - Refresh

Refresh page 

<!-- refresh content every 5 seconds -->
    <timer id="timer" delay="2000" repeats="true" />

Building and Deploying - Maven etc.

The deploy path for Webcontent folder can be configured in eclipse in the project properties:

Perhaps worth adding the lib to WEB-INF/lib as well

an example maven build file that then builds assumes /src/main/java /src/main/webapp
