module:delite/Widget

<static> hide(widget)

Hide this popup widget (until it is ready to be shown). Initialization for widgets that will be used as popups.

Also puts widget inside a wrapper DIV (if not already in one).

If popup widget needs to layout it should do so when it is made visible, and popup._onShow() is called.

Parameters:
Name Type Description
widget module:delite/Widget
Source:

<static> moveOffScreen(widget) → {HTMLElement}

Moves the popup widget off-screen. Do not use this method to hide popups when not in use, because that will create an accessibility issue: the offscreen popup will still be in the tabbing order.

Parameters:
Name Type Description
widget module:delite/Widget
Source:
Returns:
Type
HTMLElement

<static> open(args) → {*}

Popup the widget at the specified position.

Note that whatever widget called delite/popup.open() should also require activationTracker and listen for delite-deactivated event to know that focus has moved somewhere else and thus the popup should be closed.

Parameters:
Name Type Description
args module:delite/popup.OpenArgs
Source:
Returns:

If orient !== center then returns the alignment of the popup relative to the anchor node.

Type

Examples
// Open at the mouse position
popup.open({popup: menuWidget, x: evt.pageX, y: evt.pageY});
// Open the widget as a dropdown
popup.open({parent: this, popup: menuWidget, around: this, onClose: function(){...}});

Properties:
Name Type Description
popup module:delite/Widget

The Widget to display.
parent module:delite/Widget

The button etc. that is displaying this popup.
around Element | Rectangle

DOM node (typically a button); place popup relative to this node. (Specify this or x and y properties.)
x number

Absolute horizontal position (in pixels) to place node at. (Specify this or around parameter.)
y number

Absolute vertical position (in pixels) to place node at. (Specify this or around parameter.)
orient Array.<string>

When the around parameter is specified, orient should be a list of positions to try, ex. [ "below", "above" ] delite/popup.open() tries to position the popup according to each specified position, in order, until the popup appears fully within the viewport. The default value is ["below", "above"]. When an (x,y) position is specified rather than an around node, orient is either "R" or "L". R (for right) means that it tries to put the popup to the right of the mouse, specifically positioning the popup's top-right corner at the mouse position, and if that doesn't fit in the viewport, then it tries, in order, the bottom-right corner, the top left corner, and the top-right corner.

Alternately, orient can be an array ["center"], which pops up the specified node in the center of the viewport, like a dialog. It will shrink the size of the node if necessary, in which case the node must be designed so that scrolling occurs in the right place.
onCancel function

Callback when user has canceled the popup by:

  1. hitting ESC or
  2. by using the popup widget's proprietary cancel mechanism (like a cancel button in a dialog); i.e. whenever popupWidget.onCancel() is called, args.onCancel is called
onClose function

Callback whenever this popup is closed.
padding Position

Adding a buffer around the opening position. This is only used when around is not set.
maxHeight number

The max height for the popup. Any popup taller than this will have scrollbars. Set to Infinity for no max height. Default is to limit height to available space in viewport, above or below the aroundNode or specified x/y position.
