View source for Experiment:The wx wrapping function

==Set up==
- STUB - [[User:Alec|Alec]] ([[User talk:Alec|talk]]) 16:38, 23 April 2017 (UTC)
* See ''wxGraph'' project folder, and {{C|wxStaticWrappedText}} (my class, not a {{C|wx}} class)
** during an {{C|EVT_SIZE}} we copy some stored {{C|wxString}} to the label of a {{C|wxStaticText}}, we then tell it to {{C|Wrap}} passing the usable width as a parameter, the wrap function takes the bulk of this time<ref group="Note" name="Measure"/>
===Test string===
<source lang="cpp">
		wxString longText("This is long, or it will be!"); //28 chars
		for(int i=0;i!=345;i++) {
			longText = longText << " longer still"; //13 char
		}
</source>
==Models==
# {{M|w\eq 124.1\ell^{0.9762} }} - to {{M|4}} s.f. - even for {{M|\ell=40,000}} these only differ by {{M|\approx 1500}} and are in the order of {{M|3.85}}m {{M|\mu\text{S} }}
#* Actual model: {{M|w\eq }}''124.085862874602''{{M|\ell}}<sup>''0.976171971433827''</sup>
#* Created from first 4 - 6 data points and compared, {{M|x^2}}, {{M|x^3}} and {{M|x^4}} models were just fitting to plot and didn't converge outside of it
# {{M|w\eq 94.85\ell^{1.020} }} created from almost all the points except the last 1 then the last point was added to see how well it predicted 
#* Actual model: {{M|w\eq }}''94.8492202616877''{{M|\ell}}<sup>''1.02004775561656''</sup> - difference of about {{M|2.3}}k at {{M|\ell=40,000}}, they're in the order of {{M|4.7}} million {{M|\mu\text{S} }} anyway

! Result
! {{M|k}}<ref group="Note">{{M|\ell:\eq 28+13k}} where {{M|\ell}} is the resulting string length and {{M|k}} is the number of times a string is appended to to a base string to generate it</ref>
!String length
! {{C|Wrap}} time<ref group="Note" name="Measure">Actually the time to copy the string into the {{C|wxStaticText}} and the wrap time is included, but for even a short {{M|353}}-length string, the copy time was {{M|435\ \mu\text{S} }} per call, the bulk of that will be the cost of allocating memory not the copying cost. For reference the {{C|Wrap}} time for 353-length example was {{M|37\ \text{mS} }} or {{M|\approx\ 37,000\ \mu\text{S} }}</ref>
