[RkWard-devel] Images in dialogues

Hi Stefan,

sorry for the long delay.

From the programming point of view, your idea really breaks down into four 
rather separate parts:

1) Embedding static image-files (.png/.jpg, etc.) in a plugin's GUI to 
visualize some options. Should be very easy to do, and I intend to tackle 
this soon. Using the <logic>-section it will also be possible to switch 
images according to GUI settings, but images will be passive, in that they do 
not react to clicks, etc.
2) Something like an image-based radio-control. E.g. you have three different 
images on the left, each visualizing a different distribution (or whatever). 
On the right there is a short text describing each option. To select an 
option, click on the image, the choice will be shown by a border around the 
image. Will be integrated with the current <radio>-elements, as that is what 
it is functionally. Pretty straightforward in principle, but as far as I can 
tell, not supported by Qt out of the box (but maybe I'll have to look 
harder), therefore needs more work to implement.
3) Real preview of R graphs. I've tried this once, but did not succeed on the 
way I had chosen. Alternative approaches are possible, but have not been 
tried, yet. Definitely something to have in the long run, but not quite easy 
to do. Probably not coming very soon.
4) The color-choser widget. I think the way to go for this sort of 
functionality is to create embeddable plugins in pyQt (or something else). 
With rkward 0.3.5 we've gone some more way towards making this sort of plugin 
possible, but more work is needed. Not coming very soon, either, but also 
something that is definitely on the list for the future.

So the bottom line is: Those are all sensible suggestions, and eventually we 
should support all of them. Don't expect anything other than 1) in the short 
term, however. (If someone would like to work on 3) or 4), I already have 
some thoughts on these, which I could share with you, but which I have not 
written down in an itellegible way so far; just contact me, if you're 
interested).

Regards
Thomas
