<br>
I have a window with four panes: <br>
top left: LayoutFrame fractions: (0@0 corner: <a class="moz-txt-link-abbreviated" href="mailto:0.2@0.5">0.2@0.5</a>)).<br>
top right pane: LayoutFrame fractions: (0.2@0 corner: <a class="moz-txt-link-abbreviated" href="mailto:1@0.5">1@0.5</a>).<br>
bottom left pane: LayoutFrame fractions: (<a class="moz-txt-link-abbreviated" href="mailto:0@0.5">0@0.5</a> corner: 0.19@1).<br>
bottom right pane: LayoutFrame fractions: (<a class="moz-txt-link-abbreviated" href="mailto:0.19@0.5">0.19@0.5</a> corner: 1@1).<br>
<br>
self addPaneSplitters does its impressive magic; <br>
a horizontal pane splitter right across the window at y=0.5<br>
two vertical pane splitters one between top left and top right and
another between bottom left and bottom right.<br>
(The latter two has 'splitsTopAndBottom'=false)<br>
<br>
The curious thing is that the two vertical pane splitters are linked;
any one of them cannot be moved past the other one. The constraint is
in these methods <br>
<i><b>ProportionalSplitterMorph>></b></i><br>
<b>normalizedX: x</b><br>
^ (x max: self leftBoundary) min: self rightBoundary<br>
<b>rightBoundary</b><br>
^ (self splitterRight ifNil: [self containingWindow
panelRect right] ifNotNil: [self splitterRight left]) - 50<br>
<b>splitterRight</b><br>
| splitters |<br>
splitters _ ((self siblingSplitters select: [:each | each x
> self x]) asSortedCollection: [:a :b | a x < b x]). <br>
^ splitters ifEmpty: nil ifNotEmpty: [splitters first]<br>
<b>siblingSplitters</b><br>
^ self owner submorphsSatisfying: [:each | (each isKindOf: self
class) and: [self splitsTopAndBottom = each splitsTopAndBottom] and:
[each ~= self]]<br>
<br>
Does anybody know the motivation for this curious behavior? The easiest
workaround would be to hack <b>siblingSplitters </b>to return an
empty collection. Perhaps it would be better with a new preference?
(Subclassing <i><b>ProportionalSplitterMorph</b></i> does not seem
practicable).<br>
<br>
I'll be grateful for enlightenment about this curious behavior.<br>
