Hi Arjen
That looks like the class you are looking for. Those comments
shouldn't be important. They just mean that you can access x and y
exactly like in a C struct, for example wxSize mySize; mySize.x=4;.
But the comment says please don't do this.
Further down in that class is there a constructor? it will look
something like wxSize( int w, int h). It looks like a function
declaration, but with no return type. The variable names may be
different too - probably some variation on width and height or x and
y.
