is it possible to change an image of an imagelist item?

it seems only to be possible to add items to the list and destroy the complete list.
so my workaround is to destroy the list an reinitalize it. not the best way as the list disappears for some 10th of a second

Ah, I see you started to realise...

Don't anybody full you, AHK is full of such things... this is certanly not lonely spot that needs to be fixed.

ok.
i realize, i have to live with my workaround

Can you give an example why you need to replace an image instead of adding one and using it?

OMG!

Why ppl around need examples for every thing in the world.

New keyword: extraploation
New kyeword: multiverse

If I add an image to the list, the most natural thing is to be able to remove it. Those things come together:

ADD     REMOVE

cmon, lets repeat it loud:

ADD     REMOVE

ADD     REMOVE

ADD     REMOVE

you see... you understand now

majkinetor, AutoHotkey's handling of GUI has been designed as a balance between functionalities and ease of use.
If Chris has implemented all the Win32 API, there would have been no need for DllCall (except for 3rd party DLLs) but we would use a 10MB software with a 1000 page reference manual...
He chose to implement what he finds to be the most useful/used features. He can be wrong in his choices, but wish list is there to debate for that.

I found the ImageList_Replace function, which can be used with DllCall in the rare cases it is needed.
I write "rare case" because when I searched with Google for examples of use of this function, I found 88 hits (you might have more with less restrictions on languages), including the references and alternate implementations (ReactOS, Wine, etc.).

Having a perfectly orthogonal language is very nice in theory, but might not be very practical.

Remove function has nothing to do with that. It wouldn't change easines as you don't need to use it if you dont' need it, and it would add new functionality.


When did I say that all api have to be implemented ?
As usual, ppl give me extremes of my ideas. I can give extreme of your ideas too, just I am serious enough (may be hard to grasp for some) not to do so.



Oh, so if we add few functions it imediately becomes Java, like PhiLho already "explained". About your 1000 pages manual, you can always use existing and add one link: "You want more, ha, do you? Well click here for more you crazy son of a ... "



Ok, if you like, ask Jonny the boy to move this to the wish list, I wont mind

Yeah, if you put CSound as a language restriction, there is 0. What a stupid function. Nobody uses it. (its not very nice to use extreme's in discussion isn't it )


Really ?
Can you show me an example ?
I wonder what will you put as HIMAGELIST parameter.
Ah... I know... it has to be implemented all the way again, in AHK... good luck with your example that you are going to show me, right ?


I am not talking about theories here. For that, I use different nickname

the need for replacing an imagelist icon is simply speed.
it took a while to recreate the whole list. not much, but it does

the link to the msdn article looks interesting, but it would be a huge task to implement it.

You didn't understood the question. Why do you need to change an image of the list?
In other words, I just want a real world use case of this functionnality.
A Google Code Search shows 300 occurences of the ImageList_Replace function, most of them in Windows emulators or Windows API wrapper (like wxWidgets). I didn't looked at all the pages, but the first (and only) case outside these was in a program which changed an image on the toolbar. And it probably could instead change the index in the image list, which would have been faster and more logical (that's the purpose of an IL).
On the other hand, searching ImageList_Add returns more than 2000 occurences. It shows the relative importance (use) of these APIs.

The problem isn't to add new functionalities, but to demonstrate they are compelling, beyond extrapolation...

Strange how ppl evolve here from one post to another


ROFL.
Did you searh how many times wrappers are used ?
