If you run this, it displays a simple table.
If you look at the source, you can see that the calls to "fitColumnsToContents" and "fitRowsToContents" are both commented out. Note that the "fitColumnsToContents" is the replacement version you wrote a few days ago.
If I un-comment either of these, then the table columns or rows (respectively) are shrunk bigtime. There is a printf in "fitColumnsToContents" to display the cw and hw values - these clearly are garbage (far too small).
What ever have I done wrong here?
The problem is that at the time you're calling fitColumnsToContents(), the fonts haven't been created yet. I can't seem to get to the FOX home page at the moment, but if I could, I'd point you to an item in the FAQ there that talks about this issue of created versus non-created fonts (or icons, etc.) There's also some discussion of it in section 7.7 of the book, where I talk about client-side versus server-side objects.
If you just move those two calls to your create() method, e.g.
def create
super
@table.fitColumnsToContents(0,2)
@table.fitRowsToContents(0,2)
show(PLACEMENT_SCREEN)
end
You should get the desired result.
Hope this helps,
Lyle
