A container can be displayed as a popup. The popup window does not have any special frame. Popups can be displayed when an element is clicked by assigning the id of the popup to either the XulElement.setPopup(java.lang.String), XulElement.setContext(java.lang.String) or XulElement.setTooltip(java.lang.String) attribute of the element.

Popup

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

ZKComRef Popup.PNG

<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>

ZKComRef Popup2.PNG

<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:

ZKComRef Popup Position 601.png

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:

ZKComRef Popup Position.png

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

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.

The usage is in below code.

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