Re: [Sawfish] Beginner's Rep Question

[Richard <r_j_humphreys@xxxxxxxxxxx>]

Thanks for the advice.

I don't have a specific use-case at present. I wanted to learn what facilities are available; then I can think of how to use them. In this particular case some cases which I was curious about were:

- Buttons which highlight as the mouse moves over/near them. (I know that this is addressed through the inactive/focussed/clicked states - but I like to play).

- Resize handles which only appear when the mouse is over/near them.
- Buttons which slide out of the title bar in response to a click or other event.
- Disabled buttons being completely hidden (rather than displayed inactive), which would involve the other buttons being shifted along.


It is fairly straightforward for some properties to vary for each window; the title bar is already showing different text for each window (generally by using window-name or a more complex function to derive some text) so it would be feasible to use a function call to provide coordinates, size, colours etc. So I may play with that method.

If I can get that working, the last hurdle will be that I was expecting a call to refresh-window to redraw all the frame parts immediately, but I was obviously wrong. I'll keep thinking about it.

Again, may thanks for the help.

R.
