  set(txtFilter1,"font",fonts[TEXT])  -- no property named 'font' 
  set(txtFilter1,"font_name",fonts[TEXT])  -- no property named 'font_name' 
  set(txtFilter1,"font name",fonts[TEXT])  -- no property named 'font name' 

How do you do it?

  set(txtFilter1,"font",fonts[TEXT])  -- no property named 'font' 
  set(txtFilter1,"font_name",fonts[TEXT])  -- no property named 'font_name' 
  set(txtFilter1,"font name",fonts[TEXT])  -- no property named 'font name' 

txtFilter1 = create(GtkLabel)

The reason why it's called a filter is the user types something in it and the list of foods is filtered by it. For example the user types "al" and all the food names must start with "al".

set(mylabel,"modify font","Courier 12")

I can't remember all these things either, but try changing to the directory with the EuGTK demos, and typing grep font * In most cases, something like that will pull up several instances to look at.

BTW, I am not at all sure a label is the correct thing to use display a lot of items. Suppose the user types A - he's going to get a very long list, and labels are for short things. You'll find the label extends off the bottom of the screen, and there's no way to see the bottom part.

Well, of course you can write your own filter routines, but GtkListView and GtkTreeView have those built-in. Euphoria's may actually be faster, we'd have to try both and see. The advantage of the built-in filters is that you can use a single list to display different 'sets' of the data in different views, so when you change an item, it is immediately updated wherever it appears.

Even though it's written for mono, there's a good tutorial about the list & view stuff. You can easily see how to translate it to Euphoria.

Now, for the input to your filter: seems like a GtkEntry would work, if the user needs to type something. When he hits enter, your routine to do the filtering could be called:

include GtkEngine.e 
 
function Foo(atom ctl) 
	puts(1,"You pressed enter!") 
	printf(1,"Control text is: %s\n",{get(ctl,"text")}) 
return 1 
end function 
 
constant win = create(GtkWindow) 
connect(win,"destroy",quit) 
 
constant input = create(GtkEntry) 
add(win,input) 
connect(input,"activate",call_back(routine_id("Foo"))) 
 
show_all(win) 
main() 

If you want the filter to update after every character is typed (instead of waiting for the enter key) change the "activate" signal to "changed"
