I've recently wanted to be able to display ANSI content with a scrollableãinterface, and tonight I found frame.js, which seems to do the job. I startedãusing frame.js a bit tonight to see what it can do. I saw that it has aã'scrollbars' property, but it seems that even when I set it to true, it isn'tãdisplaying scrollbars. I tried making sure v_scroll and h_scroll are bothãtrue, but it still wasn't displaying scrollbars. Is that a known issue? Also,ãwould it display a vertical scrollbar if v_scroll is true and h_scroll isãfalse?ããNightfoxãã---ã þ Synchronet þ Digital Distortion: digitaldistortionbbs.comã

Re: frame.js scrollbarsã By: echicken to Nightfox on Tue Nov 24 2015 08:25:30ããHi echicken,ããAnother thing I've noticed about using frame.js to display ANSI content is thatãit doesn't seem to totally refresh the background text when scrolling the ANSIãup & down - Some text from some of the lines is left over when scrolling. Forãexample, in the following screenshots, the ")" in the origin line at the bottomãis left over when scrolling the message down (as the message text moves up):ãhttp://bit.ly/1Ntklt5ãhttp://bit.ly/1Ndg5Mjãhttp://bit.ly/1Ib9YI5ããNightfoxãã---ã þ Synchronet þ Digital Distortion: digitaldistortionbbs.comã

- When first displaying the file, it looks like the scrollbar has "holes" in it. This is a screenshot I made as an example (using white as the scrollbar foreground and light grey as the scrollbar background):

Not sure. Are you setting the background colour to LIGHTGRAY or BG_LIGHTGRAY? Is the ANSI content being loaded before or after the scrollbar is opened / cycled for the first time?

- I have an input loop in my script that waits for a keypress and scrolls the Frame when the user presses the up or down arrow, PageUp, PageDown, Home, or End. The scrollbar refreshes when I scroll up & down one line (using the Frame's scroll() method), but after using the Frame's scrollTo() method (which I'm using for PageUp, PageDown, Home, and End), the scrollbar doesn't refresh until cycle() is called a 2nd time (which happens when I press PageUp, PageDown, Home, or End in my script).

The ScrollBar doesn't actually redraw itself when you call .cycle() on it; it just updates its position info. The drawing takes place when .cycle() is called on the parent Frame. You could try calling .cycle() on the ScrollBar after you have called Frame.scrollTo() but prior to calling Frame.cycle(). (That may or may not help, but it's worth a shot.)

For the 2nd issue, I'm not sure if it's something I'm doing wrong in my script or if it's an issue in the scrollbar/frame class.

Probably just differences in the way you're using it and the way I expected to use it. In my input loops, I usually use console.inkey rather than console.getkey, and call [whatever].cycle() each time through the loop. This way, stuff gets updated as needed whether the user has pressed a key or not. (Useful if you want to update stuff in the terminal while the user is idling, etc.)

I was using LIGHTGRAY. I tried BG_LIGHTGRAY just now, and I think it actually looks/behaves better with LIGHTGRAY.

Only the BG_* values in sbbsdefs.js should be used for background colours; using the others may result in strange-looking things.

LIGHTGRAY incidentally looks better as a background here because - since WHITE is your foreground - it's like not setting a background colour at all. The foreground and background colours are OR-ed together to make an attribute number. In this case you end up with WHITE|LIGHTGRAY, which is 15|7, which is 15, which is WHITE. (You should see the same result when using any other non-BG_* colour as your background, so long as WHITE is your foreground.)

The ANSI content is being loaded before the scrollbar & frame are opened for the first time. Should it be loaded after?

Not sure - I was just curious. How are you loading the ANSI stuff into the Frame - using Frame.load(), or some other way (Frame.putmsg(), etc.)?

Ah, that seems to help. So it seems that the documentation (comments) in scrollbar.js are wrong -

Not really. The example works, but there's a crucial difference between it and what you're doing. (Which isn't to say that your way is wrong.)

if(f.cycle()) {
s.cycle();
console.gotoxy(console.screen_columns, console.screen_rows);
}
That seems to suggest that if the frame cycle succeeds, then cycle the scrollbar. But as you suggested, it seems to work better when the scrollbar's cycle() is called before the frame's cycle().

Frame.cycle() returns true if something changed, false otherwise. In my example, I'm only updating the ScrollBar if something changed in the Frame it's attached to. However changes to the ScrollBar's position won't be displayed until the Frame is cycled again. In my example, that next Frame.cycle() happens right away. In your code, there's presumably a blocking input prompt (console.getkey perhaps) in between.

The best solution would be for me to just bring ScrollBar into frame.js, and tie it into the Frame.cycle() method. Then you would use those currently-placeholder properties of Frame to enable scrollbars, and the rest would work behind the scenes - no need to manage the scrollbars separately.

What I think I'll do is leave scrollbar.js where it is, and then have frame.js load it. That way any script currently loading scrollbar.js will still have it available. Frame will then create ScrollBar instances if scrollbars are toggled on, and maintain them for you.

Even if some script is already using scrollbar.js and setting 'scrollbars' to 'true' on a Frame, it probably won't break anything. You'd just end up with two scrollbars, one layered over the other, doing the same thing, with only the topmost one visible.
