XlsReader question

in Contributed Library Questions • 2 years ago

I am new to Processing and Java so I am sure that this question will be obvious to those of you who are skilled in both. In any event I would appreciate your help.

The code below produces the following error:
The constructor XlsReader(XlsReaderTest.XlsTable, String) is undefined.

import de.bezier.data.*;
XlsTable school;
XlsReader excelTable;

void setup(){
school = new XlsTable("schools.xls");
}

void draw(){

}

--------------------

class XlsTable {
XlsTable(String fileName) {
excelTable = new XlsReader (this, fileName);
}
}

Many thanks in advance,

Ron

Old problem: if you call a library constructor needing 'this' from a class, you have to pass the 'this' of the sketch (PApplet) to the class so it call the constructor with the reference to the PApplet, not to the class itself.
That's probably confusing.
In short, call school = new XlsTable(this, "..."); and the constructor should be XlsTable(PApplet pa, String fileName) { excelTable = new XlsReader(pa, fileName); }
