src Void close()

Close this popup. If popup is already closed this method does nothing.

src Void fitBounds()

Fit popup with current window bounds. This may move the origin of where popup is opened, or modify the width or height, or both.

This method is called automatically by open. For content that is asynchronusly loaded after popup is visible, and that may modify the initial size, it is good practice to invoke this method to verify content does not overflow the viewport.

If popup is not open, this method does nothing.

src Align halign := Align.left

Where to align Popup relative to open(x,y):

• Align.left: align left edge popup to (x,y)
• Align.center: center popup with (x,y)
• Align.right: align right edge of popup to (x,y)

src Bool isOpen { private set }

Return true if this popup currently open.

src new make()

src protected virtual Void onBeforeOpen()

Protected sub-class callback invoked directly before popup is visible.

src Void onClose(|This| f)

Callback when popup is closed.

src Void onOpen(|This| f)

Callback when popup is opened.

src Void open(Float x, Float y)

Open this popup in the current Window. If popup is already open this method does nothing. This method always invokes fitBounds to verify popup does not overflow viewport.
