layout support?

[gansm]

If you need a flexible layout, you can overload the adjustSize() method.
An example can be found in examples/ui.cpp.

Planned for the future is an FGrid widget container, which organizes its child widgets into rows and columns.

[user1095108]

The issue transcends adjusting the size to different screens. There exists a Turbo Vision port for Linux/Windows, that has implicit 80x25 assumptions. Nasty.

I'm afraid I don't understand the question. I can't see your point.
If you have a flexible layout, then it also works in 80x25.

[user1095108]

That's the point. I wrote a tvision app once and once I ssh-ed to the shell and tried out the app, one could see there were some 80x25 assumptions in library code, as the phone terminal emulator had very strange dimensions, you could see artifacts stemming from the 80x25 assumptions.

Unfortunately, I still don't understand your question.
Have you a problem with tvision or Final Cut?

Final Cut gets its resolution information via TIOCGWINSZ. If this doesn't work I use the environment variables COLUMNS and LINES. Otherwise I assume a standard xterm resolution of 80x24.

[user1095108]

I was merely making a philosophical observation. Not only do layouts provide flexibility are regards different screen resolutions, they also guard us from making potentially invalid assumptions (like the 80x25 assumption in tvision). As for me personally, I was looking for a TUI library, that would support something like the Qt's QScrollArea, but no luck :(

BTW: If you intend to implement signals/slots, take a look at:

Otherwise, you can close this issue.

There is FScrollView that should be what you are looking for. For an example you can look into the examples/scrollview.cpp source code.

A callback functionality is already implemented. For example, you can use emitCallback("clicked") to generate a signal that can call a own routine via widget.addCallback("clicked", F_METHOD_CALLBACK (this, &classname::method)).
