[Implemented] Remove CreateGadgetList()

[Trond]

How about removing CreateGadgetList()? In the rare case you want to open a window without gadgets, does it matter if a few bytes are wasted?

And what about merging OpenGadgetList() and UseGadgetList()? They do basically the same except with gadgets and windows. Illogically one takes a PB number and the other one takes an ID. If both used the ID they could be merged into one function.

I find that's a cool idea! Although it doesn't need much typing to write CreateGadgetList(), it's still quite annoying to do it for every window you want to have some Gadgets in it. In most other programming languages that I know, there is a similar function usually named InitWidget, etc..

What sense does it make that CreateGadgetList() acceptss hWnd's only? You cannot create gadgets onto other windows, so it would be good, if CreateGadgetList() just accepts #WindowID's.
I tried to create gadgets onto other windows (not owned by my program, but it didn't worked.

(Sorry, if I'm wrong)

Trond posted something here where he added a button to an external window:

Also, I remember reading that CreateGadgetList can be used to create many
lists, not just one, so the user can select which list to use at any given time,
so I think that's why the command exists.

@ PB:
Sorry, didn't know that it's so easy:

Code: Select all

c=FindWindow_(0,"Calculator") 
CreateGadgetList(c) 
ButtonGadget(0,0,0,100,20,"test") 

iirc, I tried the same, but I've failed...

Because your program then ends and PB destroys the button before you can see it...

Ahhhhhhhhhhhhh! So that's the reason! THANK YOU!

You can't do that. You can't process the window messages for an unowned window. The best you could do is create a borderless window the size of the gadget and have it move with the target app, creating the illusion that you've put a gadget on it. There is a post from the team dealing with this:

I don't get it. If you're going to open a window without gadgets, then you
wouldn't need to call CreateGadgetList at all, so what's the problem here?
Isn't that like saying: remove DeleteFile because my app won't be deleting
any files?

I think it would be cleaner and less coding if every window you opened automatically came with a gadgetlist unless you passed the flag #PB_Window_NoGadgetList, which you'd only do infrequently. It would save typing the CreateGadgetlist(Windowid(0)) every time you open a window. But the command is still needed for API-created windows, so it can't really be retired.

Good idea about a #PB_Window_NoGadgetList flag for OpenWindow!

The flag sounds like a good solution.
