Employment/Purpose

The popup is a container that does not have any special frame. You can associate a popup with any component by specifying the popup's id at one of the following attributes:

    <button popup="popup_id"/>
    <button tooltip="popup_id"/>
    <button context="popup_id"/>

    <popup id="popup_id">
        this is a popup
    </popup>

Example

<separator bar="true" />
<label value="Tooptip for Another Popup" tooltip="any" />
<popup id="any" width="300px">
	<vbox>
		ZK simply rich.
		<toolbarbutton label="ZK your killer Web application now!"
			href="http://www.zkoss.org" />
	</vbox>
</popup>

<textbox popup="popup, position=after_start"/>
<popup id="popup" width="300px">
	<vbox>
		ZK simply rich.
		<toolbarbutton label="ZK your killer Web application now!"
			href="http://www.zkoss.org" />
	</vbox>
</popup>

Position

You can simply specify a popup's position when attaching to a component by

• built-in position
• x, y coordinate

<button popup="popup_id, position=overlap_end"/>
<button popup="popup_id, x=50,y=50"/>

Since 6.0.1 ZK supports the following position string:

overlap, overlap_end, overlap_before, overlap_after are kept (still available) for backward compatibility. They are identical with top_left, top_right, bottom_left, and bottom_right, respectively.

Before 6.0.0

The 14 possible positions are provided below:

The following illustrates the simplicity of usage,

<popup id="pp">
	Here is popup
</popup>
<button label="before_start" onClick='pp.open(self, "before_start");' />

Upon clicking the button the popup component will appear in the relative position specified. In this case the position is just above the button.

Methods

There are several overloading open() methods available, please check javadoc

Toggle Popup

 Since 7.0.0

If a popup/context menu is assigned to a target component via the popup/context attribute, the popup up will show up when the user clicks on the target component. Click the target component again, the popup will still show up by default. As of 7.0.0, The popup/context attribute supports additional toggle type, which could make target component act as a toggle switcher. If the popup has not shown up yet, click the target component will cause the popup to show up. If the popup is showing up, click on the target component again will toggle the popup to hide. The usage is in below code.

<button label="Popup" popup="id, type=toggle"/>

Tooltip Delay

The tooltip attribute can also support a delay, the following code outlines how to accomplish this.

<label value="Tooltip" tooltip="popup_id, position=before_start, delay=500"/>
