In EWB1 I often used TImage to build GUI's. Autosize and visibility in
the IDE helped a lot.

In EWB2 that seems to be different. Will there be an additional
Image-control in the final version?

Thanks.

And:

1) Can you remove the border?
2) What ImageLayout do you use to get your image central and fitted without any skewing?

With the given controls and without changing interfaces, the only way I
see is to use a TBasicPanel.

The image can be loaded as a background image, the constraints can be
set to the image's bounds, borders and corners can be removed... A lot
of handwork.

Interesting. I popped a TImage onto a form, then looked for where to
set the image. Only property I can find is in the Background, and that
has all the options one might want for an image - centre, fill, all
sorts. But running it shows the border and the "standard image" on top.
I wonder if that isn't finished.

A look at the source and interface for TImage shows that it is quite
smart, allowing for normal, hot, and focused states (hence the border).
I can't work out how the image gets changed though.

Even so, it won't be hard to have a "TStaticImage" which doesn't do
anything fancy.

I look forward to hearing Tim's thinking on this though - I expect it
is quite powerful.

No, the TImage control is *the* control for *dynamically-loaded images*.
That's why it's on the Web page instead of the Standard page.  If you want a
static image that is included in a form, then you should use one of the
panel controls with a background image.  Background images are always
included as part of the form.

The way images work in EWB 2 had to adjust to the fact that the design-time
environment is completely different and there are limitations on what kind
of binary data can/cannot be loaded at design-time, especially for images.

Mark,

<< 1) Can you remove the border? >>

Not for the TImage control, no.  It allows for focus, so it needs a border.
Of course, this is just the standard interface: you're free to develop your
own interface that shows focus in a completely different way, or not at all.

ImageLayout.Position setting of ptCenter.

See my first reply to Uli.

That's bug in the interface, and it also affects the TBrowser and TPlugin
controls - the standard background is set on the Client element instead of
the Base element.  It's only supposed to be there as a default that can be
cleared at design-time by setting the Background.Image.Name property to ''.

OK, I got it.

Any chance to implement something like "Autosize"? IOW: a property that
is available, if a background image is assigned?

Thanks Uli

Uli,

<< OK, I got it. >>

Actually, I need a static image without a border for the example projects
(logo), so I might include one in the component library.....

I'll see what I can do.  Normally, you don't want the size of the image to
affect the layout, rather the other way around.  But, I can certainly see
some cases where you would want the size of the image to affect the layout,
such as with flowing sets of images like a Netflix/Amazon Video/Hulu
interface.
