<p>Hi Marcel,</p>
<p><br>
</p>
<p>actually I find re-evaluability quite often useful - for example, when I would like to take the LayoutFrame and set it to another Morph. At the moment you need to totally deconstruct + rewrite the expression to reuse it, while on the other hand you can directly
print-and-eval points and rectangles. For beginners, it also helps to understand how the Objects are created.</p>
<p><br>
</p>
<p>Is</p>
<p><span>LayoutFrame fractions: (0.25@0 corner: 0.5@0.42) offsets: (4@0 corner: 0@ -20)</span></p>
<p><span>actually harder to read than</span></p>
<p><span><span>a LayoutFrame( l 0.25+4 t 0+0 r 0.5+0 b 0.42-20 )</span><br>
</span></p>
<p><span><span>?</span></span></p>
<p><span><span>(Imho, the latter with the unfamiliar non-Smalltalk syntax looks much more confusing to me. :) )</span></span></p>
<p><br>
</p>
<p><span><span>Best,</span></span></p>

Hi Christoph,
<div><br>
</div>
<div>I recently changed that to be more valuable for me when debugging layout issues. Feel free to add more "ifNil" checks if needed - there are already some.</div>
<div><br>
</div>
<div>However, there is no need to make that string re-evaluable. It's designed to fit the human eye. At least mine. :-)</div>

<p>Hi all,</p>
<p><br>
</p>
<p>is anyone attached to the current <span>LayoutFrame>>#printOn: design?</span></p>
<p><span>The current one fails if some instvars are nil. This is the case for SystemWindowButtons.</span></p>
<p><span>Furthermore, I never liked the current string representation, it has a quite cryptic look and does not match the common way you create a LayoutFrame using #fractions:/#offsets:.</span></p>
<p><span><br>
</span></p>
<p><span>Would anyone mind me to rewrite #printOn: in order to return a re-evaluatable string? Are there any dependencies?</span></p>
