Re: [Pharo-project] Polymorph - TabIndex and layoutFrames questions

Sept. 14, 2009


      #position: and #extent: etc. won't work since the owner is laying out as per 
the layout frame.
You'll need to adjust the offsets instead...

...
iÂ´m already using fractions and offsets, through my class CLDecorMorph...
http://paste.lisp.org/display/87049
(Note: in that class properties as #position or #top, #left etc  be
relatives to owner)
IÂ´m use the owner always with ProportionalLayout and the "anchors" with 
the
fractions-offsets mechanism. The problem is when I try set the #position: 
or
#extent: accessors. DonÂ´t works.

1. "Fixed" positioning can be achived by setting the fractions to 0@0 for
top-left and bottom-right then using the offsets.

questions
1. I have always work with owners in ProportionalLayout, donÂ´t let work
with another layoutPolicy in the canvas designer. In view designer exists
the possibility of "anchor" a widget to top, left, down and right. That 
is
all need the user ( for the moment ) for anchor a widget, but fails to
change size and position.Exists the possibility of do it in
ProportionalLayout on owner?
2. Then i understand than changing the order of submorphs that works? I
will probe.
Regards and many thanks.

1. position/extent depends on how thae morph is laid out in its 
owner.
    LayoutFrame is used when the owner specified a proportional layout,
use the
    fractions to pin corners and the offsets to.. offset.
    If the owner specifies no layout then postion/extent work as 
expected.
    For table layouts things are more complicated (see 
hResizing/vResizing
etc.)
2. Tab order (keyboard navigation) follows the order of the submorphs
at
    present. Add your morphs (using addMorphback: or via the Polymorph
    row/column type stuff) in the order you want navigation to follow.
