That sound like bad idea, to no longer point direct to a class using pointer's.

If you are using ID's insted, you actually need to search for ID every time you are changing a property, the search time in a linked list as we think is good in Amiga world, but it is shit design, require you search every node in list, to find the id in the worst case.

1. First of all, we should not use linked list.

2. We should try to get from point A to point B as quality as possible, search algorithms are normally slow. Try to avoid it everywhere its possible. We do not wont slow GUI, that do not respond and do takes for every to resize.

3. Some times you need to write it as multithread program, its useful to let threads update gadgets, all new GUI’s should have built in thread safety. (Mutex/Lock/Unlock)

I wouldn't like to challenge your ability to read an article in English, but... what on EARTH are you talking about???

This is what I'm reacting to.

Quote:

In the SpeedBar Gadget, an element is referred to by a pointer to an Exec list node. (In other words: the class exposes the actual implementation to the programmer, which I think is wrong.)

I’m saying ID’s are bad, in the article it did suggest using ID’s, I'm suggest using index numbers instead, if possible, or maybe provide method to obtain the index number.

Using index number cut down access time to the class, because wont need to search the nodes or items.

Use vector’s or something similar, not linked lists.

The numerical ID is just an abstract way for the programmer to address a toolbar element on the API level. How the class accesses elements internally is another thing.

I would agree that a linked list could slow things down if the gadget had to scan the list looking for a named node (i.e. for a string ID), but this is not what the ToolBar Gadget does.

if the latest blog has peaked your interest about the capabilities of versatile Toolbar Gadget Class then the clipboard manager ClipViewer is the latest utlity to be adapted to use it.
