I tried to run the program and ran into 2 errors:

Error #1:

Quote:---Error: could not open '/boot/home/yab_work/Templates/Toolbar': No such file or directory

It would appear yab-IDE does NOT like files with spaces in the names (which seems odd as this is a pre-packaged program FOR Yab)

Error #2:

Quote:---Error: in /boot/home/yab_work/Templates/ToolbarTemplate.yab, line 6: couldn't open library '/boot/home/config/settings/yab/Toolbar.yab'
---Error: Program not executed

I checked, and sure enough the 'yab' directory is missing from '/boot/home/config/settings/yab'
What's the work-around? Reinstall Yab via HaikuDepot?]]>

I have a very small C++ application that retrieves some information via web api to retrieve some live data on the internet. The C++ compiled with no issues and runs perfectly.

My Yab:

Code:
#! /bin/yab

PRINT SYSTEM$("./myApp")

Code:
#! /bin/yab

PRINT SYSTEM$("./myApp")

The C++ program when ran in Terminal outputs a single line of text. I want to DRAW TEXT to a window. That wasn't working, so I figured I'd just use PRINT to get something in the console to see if that was working... it wasn't. All files are in the same working directory.

I've completed 1 subroutine, saved it as 'routineExample.yab' and then used "EXPORT SUB routineEXAMPLE()" and then in my main program I call it with "IMPORT routineExample" however, the imported subroutine isn't sharing variables I've declared in my main program & which I rely on in routineEXAMPLE().

Is it possible to do this?

Also, curiously, when I import the subroutine file, I cannot used "#! /bin/yab" at the beginning of the imported .yab file or I get an error.]]>

One of the applications I am developing - I think - will turn out best (from a user experience) if I use Stackview to change views depending on how the user interacts with the main application.

Example: I want to have several buttons on the main window that lead to other sections "inside" of the application. Instead of having a button open a whole new window (which doesn't look good if there are window's all over the desktop) I figured, why not just use Stackview to generate a view with the exact same dimensions as the main window's view, allow the user to use buttons, lists, etc and then if they click a "Back" button, it will take them back to the original window (or view).

That being said, Yab-Documentation doesn't really go very "in-depth" with their synopsis or explanation of Stackview. I guess it's not impossible to have a whole bunch of things going on inside different views.

This all being said, this leads me to my final point: how much input/output/widgets can I have going on inside different Stackviews? Can I treat each Stackview like a window in terms of the content that's drawn on said view? Can I have a view with a BoxView, a field that takes input from the user, buttons, &etc? Or is there a better way of doing this? Initially I thought I'd just open a window directly on top of the main window, that way it looks like one application, but if the user accidentally bumped or moved the window, then it would reveal the original one below it, and that doesn't make for a nice, clean, user-experience.

If this post seems "a bit of a ramble", my apologies. Just learning Yab and the breadth and widths of its capabilities.

Cheers.

EDIT: I did visit Besly's site for more info on "Stackview" but it looks like all their links on different resources and information are all broken. If you visit this LINK, and stroll down to Stackview, there's a hyperlink that is broken/leads nowhere.]]>

When I close this second window, the program doesn't switch back to the first window. The first window stays 'greyed' (Disabled) and waits for my to click it, bringing it back and the tab once again goes from grey to yellow.

How can I change this so that the first window is brought right back to the front (enabled) immediately upon closing the second window.

Thanks.]]>

I'm trying to recreate an old utility called status in yab, this shown a statusbar and it's updated from bash...

[Image: statussc.png]

Before start i'm asking if it's possible with yab, and if it, how is the better way? Im thinking in a program reading a file every x seconds and change this file with the % in every pass...

But sure exists a better solution.

Thanks in advanced!]]>

Having finished (for now) Dungeon of Danger, I'm looking at my next project: porting Telengard from TRS-80 BASIC to Yab. For this one, I've implented new PRINT statements to work on a View.

However, I realize that I'm going to have to use inverse video (well, not have to, but it would be nice) but I can't figure out how to get that to work.

I know I can DRAW SET BGColor and HighColor to get that classic 'green on black' look, but no matter what I try, I can't get black on green, unless I set BGColor to green, which isn't useful because it turns the entire view's color to green.

I see there's a LowColor, and I have no idea what that's for.

So... is there an easy way to draw text while mixing background/foreground colors?

Thanks!]]>

However, if I run the basic code, it works fine. I'm importing two other files (neither of which have this subroutine it's complaining about).

Any ideas on that one?

Ah. Never mind. For some reason I had it as "export sub" even though it was in the main file. Removing 'export' got it to work. Seems a bit strange to me, but there it is.]]>

1. With a TEXTCONTROL, how can I tell if the ENTER key has been pressed?
2. I can create RADIOBUTTONS and SET them, but how do I tell which one the user has set?
