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.

since 6.0.1

As of 6.0.1, we provided more options for Popup position: 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.

The following illustrates the simplicity of usage,

<popup id="pp">
	Here is popup
<button label="before_start" onClick=', "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.

Or specify these positions using the following code.

<button id="btn" label="overlap" width="300px" height="300px" popup="component_id, position=overlap_end"/>

In addition to this more options are available such as positioning by x and y co-ordinates as demonstrated below.

<button id="btn" label="overlap" width="300px" height="300px" popup="component_id, x=50,y=50"/>

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 label="Tooltip" tootlip="id, position=before_start, delay=500"/>
