Hi Jean-Noël, I may well be wrong here, but from my understanding, the alignX/Y properties only work if the parent layout arranges its children in a cell-like structure. From what I can see, apart from Dock only HBox, VBox and Grid support them.
I'd use a Grid layout to achieve what you're trying to do, but that doesn't mean there isn't a more elegant solution ;-) Regards, Daniel Jean-Noël Rivasseau schrieb: > Hello, > > I have a simple Composite widget (container) and I want to place 4 images: > > * first is centered horizontally and at top vertically > * second is centered horizontally and at bottom vertically > * third is left horizontally and centered vertically > * fourth is right horizontally and centered vertically > > I wanted to use alignX and alignY for this. > > The docs say: > > Horizontal alignment of the item in the parent layout. > > Note: Item alignment is only supported by LayoutItem > <http://demo.qooxdoo.org/current/apiviewer/#qx.ui.core.LayoutItem> > layouts where it would have a visual effect.
