prev sib - how?

hogi — Sat, 01 Jun 2024 15:13:53 GMT

I want to get in this display tree from the Axis Box to the TextEditBox:

but with the below code, I get stuck at step 2: going to the previous sibling:

Names Default to Here(1);
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
gb = dt << Graph Builder(

	Variables( X( :height ), Y( :weight )),
	Elements( Points( X, Y) )
);
	
show(start= report(gb)["Graph Builder",AxisBox(1)]);
show(step1 = start << parent());
show(step2 = step1 << Prev Sib()); // -> empty. doesn't work
show(step3 = step2 << child());

The Properties Widow does not appear to show all levels of the hierarchy. The Show Tree Structure window has an additional layer that needs to be traversed to get to the TextBox() you are looking for

I was able to get to the TextBox() with the below modifications to your illistration

show(start= report(gb)["Graph Builder",AxisBox(1)]);
show(step1 = start << parent());
show(step2 = step1 << parent());
show(step3 = step2 << Prev Sib()); 
show(step4 = step3 << child());
show(step5 = step4 << child());

which has the below results

start = Report(gb)["Graph Builder",AxisBox(1)] = DisplayBox[AxisBox];
step1 = start << parent() = DisplayBox[GraphBuilderAxisBox];
step2 = step1 << parent() = DisplayBox[GraphBuilderComponentBox];
step3 = step2 << Prev Sib() = DisplayBox[GraphBuilderComponentBox];
step4 = step3 << child() = DisplayBox[GraphBuilderTitleBox];
step5 = step4 << child() = DisplayBox[TextEditBox];
