[Fxruby-users] Sorting a FXTable

[Jamey C. <jc...@tw...>]

I must be crazy.  After Lyle answered my question about sorting a 
FXIconList, I spent the next few days coding my app using the IconList.  
I got it all done.  It looks good.  It's responsive.

So what do I do, I start messing around with FXTable, because, even 
though IconList works, I would REALLY love to have grid lines, 
alternating row background colors, and column justification in my 
listviews.  So, I couldn't leave well enough alone.  I'm thinking about 
ripping the IconLists out of my app and replacing them with Tables.

I've got most of the functionality I need working for the Table, but I 
have (again) come upon the sorting issue.

FXTable has a sort and a sort_by method.  Using Lyle's IconList example 
as a starting point, I started messing around with the sort method.  I 
overrode the FXTableItem's <=> method, but I ran into my first problem.  
Whereas the sortItems method in IconList was using the entire 
tab-delimited row, it was easy for me to split the row into an array and 
specify the column I wanted to sort on by using an index to the array.

However, since the TableItem represents only one cell, it seems to be 
defaulting to the first column of the Table.  I'm stumped as to how to 
get it to sort by another column.

Also, although the sort method does call the TableItem's <=> method, and 
the <=> method does return a -1, 0, or 1 based on the current value and 
the argument's value, it does not appear to be actually producing a 
table sorted on the first row.  What I mean is, even though I can see 
the sort method actually running and calling <=> for each cell in column 
0, the table is not resorted after the method finishes.

So that's my question with the sort method of FXTable.  I also looked at 
the sort_by method.  It appears that the sort_by method is looking for a 
code block that it will pass an entire row of cells to.  For a while, I 
thought I had found what I needed.  But I'm not sure what I'm supposed 
to put in this code block.

Anyway, any light shed upon FXTable sorting would be greatly appreciated!
