Hi you all,

I have built a TImageList that contains several Icons, now what I need to do is, to draw them dynamicaly on the form, and that they could be dynamicaly changed (for examle an icon of a led that comes on and off).
What I thought would serve the purpose was to build TImages and connect them to the TImageList.
But , allas , I can't find the property that holds the handle to the Image list I have built.

Thanx in advance.
Zvi.

Hi,

Try this:

Image1.Picture := ImageList1.GetImage(1);

Hi, Tasomia.
There is no such function as get Image, only GetImageBitMap, and that does not do the work.
If I use the Picture property, I need to use a function that'll return a TPicture or a handle to one.

HI,
You can Add and Insert methods of TImageList to add and insert
new images (TBitMap).
You can use GetBitmap method to get the required image from your ImageList.
Maybe I didn't understand exactly what the problem?
Sincerely,
Nestorua.

Hi.
TImageList have also Draw method. You can draw icon from TImageList direct on canvas.

I will try all your proposals later today,
but I remeber I used (a year ago) some property of either TImageList or TImage that made a kind of "connection" between them (I think I gave the TImage object the name or a handle of the TImageList object).

I'll be more specific in about 5 hours.

Thank you all.
