[Pharo-dev] Layout in bloc

Aug. 28, 2016

      Hi!

I am working on a popup support in Bloc and I am facing a problem. Consider the following code:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
	space := BlSpace new.
	space root layout: BlLinearLayout horizontal.
	10
		timesRepeat: [ | e |
			e := (BlRectangle new extent: 20 @ 20) asElement.
			e background: Color random.
			space root addChild: e ].
	space root children withIndexDo: [ :e :index | e translateBy: (index * 30) @ 10 ].

	space root children do: [ :e | 
		e
		addEventHandler:
			(BlEventHandler
				on: BlMouseEnterEvent
				do: [ :evt | 
						| txt |
						txt := BlText new
							position: evt position;
							fill: Color red;
							text: 'Hello World'.

						e parent addChild: txt ]).

		 ].
	space show
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

If you uncomment the second line (âspace root layout:â¦â), then the string hello world is added text to the element in which the mouse enter. With the layout, the string is added at the end of the line.

I like very much the idea of having the layout applied when elements are added (even I suspect we may have scalability issues very soon), but in that situation, this is not wished.
