Hey folks. I just published 0.9.1-SNAPSHOT and would love to get some feedback before a full release. You can try it out by pointing to `maven { url = uri("`https://oss.sonatype.org/content/repositories/snapshots`") }` Here's what's included so far... New PopupManager You can now present top-level Views that will cover all other existing ones in a safe and reliable way using the new

PopupManager

. Before, you could make custom popups by directly adding items to the

Display

. This worked in many cases, but had a lot of limitations. For example, Views added this way would be affected by any

Layout

on the

Display

, which meant you couldn't control these Popups as easily. Also, new Views added to the

Display

after a custom popup was shown could overlay the popup. So there was no way to guarantee that a popup remained the top-most View. The new PopupManager fixes these limitations and provides a simple API for showing popups. Any View Can Be A Popup The PopupManager's API works with

View

, so you can make anything a popup. Simply do the following:

popupManager.show(myView) {
    it.center eq parent.center
}

// ...

popupManager.hide(myView)

Views that are shown as popups will automatically become top-level (being removed from their existing parent if already displayed) and sit above all other existing Views. Hiding a popup removes it from the

Display

, but it won't return the View to a previous parent if it had one. Popup Layouts Popups are shown with layout information directly. There are two ways to show a popup: relative to the

Display

, or relative to another

View

and the

Display

. There is an API call for each: Here,

myView

is positioned with only a "reference" to the Display (parent).

popupManager.show(myView) {
    it.center eq parent.center
}

But sometimes a popup needs to be positioned relative to another View. This shows how to place

myView

so it tracks the bounds of

someView

. The PopupManager will handle keeping the popup aligned with

someView

.

// myView is positioned with only a "reference" to the Display (parent)
popupManager.show(myView, relativeTo = someView) { popup, anchor ->
    <http://popup.top|popup.top>     greaterEq 0                             // Popup top-left always visible
    popup.left    greaterEq 0                             // Popup top-left always visible
    popup.width.preserve                                  // don't shrink popup
    popup.height.preserve                                 // don't shrink popup

   (popup.right   lessEq    parent.right ) .. Strong      // stay in parent as long as doesn't compress popup
   (popup.bottom  lessEq    parent.bottom) .. Strong      // stay in parent as long as doesn't compress popup 
  
   (<http://popup.top|popup.top>     eq        anchor.bottom + 10) .. Medium // follow anchor, as long as stronger constraints not in conflict 
   (popup.centerY eq        anchor.centerY    ) .. Medium // follow anchor, as long as stronger constraints not in conflict
}

More Powerful Text Rendering Text Alignment There is a new

TextAlignment

enum that controls how wrapped text is displayed within its margins. This is a replacement for

HorizontalAlignment

, which currently uses

Left

,

Right

(instead of

Start

,

End

) and does not support

Justify

. You can justify text by doing the following:

canvas.wrapped(
  text,
  at          = Origin,
  leftMargin  = 0.0,
  rightMargin = width,
  alignment   = TextAlignment.Justify,
  fill        = Black.paint
)

canvas.wrapped(
  styledText,
  at          = Origin,
  leftMargin  = 0.0,
  rightMargin = width,
  alignment   = TextAlignment.Justify,
)

Letter, Word, And Line Spacing You can now control the way letters, words and lines are spaced when rendering text. Letter and words spacing can be provided to the text rendering methods on

Canvas

using the new

TextSpacing

class. This information can also be passed to

TextMetrics

when measuring text.

Label

also has support for both letter and word spacing. Line spacing can also be specified whenever you deal with wrapped text. APIs •

Rectangle.toPath

that allows specifying each corner radius • Exposing

insets

in

simpleTextButtonRenderer

function •

repeat

and

loop

animations can now have delays •

Canvas

can now render wrapped text with custom line-spacing •

Label

now has

lineSpacing

property which controls how it displays wrapped text • Animatable Properties are no longer restricted to use within Views • New method to create

Ellipse

and

Circle

by inscribing within

Rectangle

• New

Circle.diameter

property • New constructor for

StyledText

that takes a

String

and

Style

Accessibility • Browser ◦

Button

now sets

accessibilityLabel

to its

text

if no label is already provided ◦

HyperLink

with native behavior will now apply aria-label to the anchor tag using the HyperLink's text when the

AccessibilityManager

is present Fixes | Improvements • General ◦ Bug with empty AnimationBlock when created during active animation ◦ Wrapped text not correctly aligned ◦ Bug in

FilteredList

iterator.remove ◦

CommonLabelBehavior

no longer provides an x offset for wrapped text since the alignment is handled correctly by

Canvas

◦ Edge case where layout can hang b/c of double imprecision ◦ Issue where

CommonLabelBehavior

overrides

Label.foregroundColor

on uninstall ◦ Bug where incorrect item could be removed from

RenderManagerImpl.pendingLayout

◦ Bug where some View properties lost during behavior install ◦ Bug where some views not cleaned up by

RenderManager

◦ Bug in pointer handling when

Display

transformed ◦

ToggleButton

no longer relies on being displayed to listen to its model ◦

StyledText.text

now returns correct value • Browser ◦ Misidentifying elements as native scroll panels led to incorrect pointer behavior ◦ Reuse instances for linear/radial gradient paints ◦ Reusing clipped images ◦ Hyperlinks now open in new tab ◦ Shadow render bug when using SVG ◦ Element sometimes not reused when drawing shadow ◦ Remove overflow on element w/ shadow ◦ Fixed wrapped

StyledText

rendering ◦ Wrapped

StyledText

now supports text decoration on previously unsupported cases • Desktop ◦ Fixed SVG image file loading issue ◦ Fixed rendering of images with radius ◦ Issue where font families weren't being properly tracked and therefore incorrectly applied ◦ Incorrect paragraph width measurement
