Users feedback, discussion
Markus Gans, I am really impressed of the work you have done! In comparision with dialog/newt-snack/ncurses/npyscreen it is like a breath of fresh air. Congratulations and please continue.
I think your library will get more attention if there is a place where users (like me) can ask questions, ask for advices, etc. What shall it be? A mail list? A web forum? Probably the easiest solution (it does not require anything to setup) is to use Stackoverflow with [final-cut] tag?!
Many thanks for your reply and your praise.
The using of an alternative and more established place for the user feedback sounds good. I joined Stack Overflow now. You can find me here: http://stackoverflow.com/users/story/7607413
Unfortunately, I can not create the tag "final-cut" without asking a question.
http://stackoverflow.com/questions/42408243/support-for-table-grid-widget-in-final-cut About tag "final-cut": I need to increase my reputation on stackoverflow to be able to create tags.
I don't have a macOS on my computer, but I'm using a compile-run with macOS on Travis-CI. The use of macOS should therefore be possible. Of course, I would appreciate a positive feedback.

I got this error message when try to compile hello sample. fterm.h:57:12: fatal error: 'gpm.h' file not found #include <gpm.h> (if this is mouse daemon, I can't find for MacOS ver.)
I have checked emac in Macport. This is how they implement the mouse. https://searchcode.com/codesearch/view/27232327/
I have download gpm from github since it can support xterm. Then I compile with g++ -I/Library/finalcut/include -o hellofinal hellofinal.cpp and I get linker error: Undefined symbols for architecture x86_64: "FMessageBox::setText(FString const&)", referenced from: _main in hellofinal-0f9b96.o "FMessageBox::FMessageBox(FWidget*)", referenced from: _main in hellofinal-0f9b96.o "FMessageBox::~FMessageBox()", referenced from: _main in hellofinal-0f9b96.o "FApplication::FApplication(int const&, char**, bool)", referenced from: _main in hellofinal-0f9b96.o "FApplication::~FApplication()", referenced from: _main in hellofinal-0f9b96.o "FDialog::exec()", referenced from: _main in hellofinal-0f9b96.o "FString::FString(char const*)", referenced from: _main in hellofinal-0f9b96.o "FString::~FString()", referenced from: _main in hellofinal-0f9b96.o
Then I tried to compile with g++ -I/Library/finalcut/include -o wtui hellofinal.cpp /Library/finalcut/src/fmessagebox.cpp get this error: error: "Only <final/final.h> can be included directly." #error "Only <final/final.h> can be included directly."
When I try to compile manually, error: "_tgetent", referenced from: FTerm::init_termcaps() in fterm.o "_tgetflag", referenced from: FTerm::init_termcaps() in fterm.o FTerm::init_termcaps_booleans() in fterm.o
Yes I know it is working on MacOS since I can make samples & run it. May I know what is c++ flag to compile it.I tried g++ -I/mylibrary/finalcut/include /mylibrary/finalcut/src/*.o -o hello hello.cpp but no success
Thank you for your feedback. I'm a little bit confused that the configure script has found a gpm.h on your system.
You should try the following commands:
autoreconf -v --install --force
./configure --prefix=/usr
make
If that doesn't help, you can also explicitly disable GPM support:
./configure --prefix=/usr --without-gpm
make
How to use the library (a little example):
#include <final/final.h>
using namespace finalcut;
int main (int argc, char* argv[])
{
FApplication app(argc, argv);
// Note: Use Shift+F10 or Ctrl+^ to close the dialog
FDialog dialog(&app);
dialog.setText ("A dialog");
dialog.setGeometry (FPoint(25, 5), FSize(30, 10));
app.setMainWidget(&dialog);
dialog.show();
return app.exec();
}
Compile with:
g++ -O2 -lfinal dialog.cpp -o dialog
It is important that you don't forget to include the libfinal via "-lfinal".
Yes, thank you. With "-lfinal" flag I'm able to compile my code. Thanks.
I have downloaded and make & install on ubuntu 17.04 but can't compile my code with same way I compile on Mac. On Mac, I download gpm first before make & install final cut.
A port to Microsoft Windows isn’t possible, because there are neither POSIX libraries nor a terminal emulator available.
For the compiling under Ubuntu you probably need some development packages.
apt-get update && apt-get install autotools-dev automake autoconf autoconf-archive libtool libglib2.0-dev libncurses5-dev libgpm-dev
I added the [finalcut-tui] tag on SO. Your tui doesn't work too well on my arch linux though within lxterminal :) All blinking and stuff.
Thanks for your tagging.
LXTerminal is a VTE-based terminal emulator and should not cause any problems.
Can you please compile Final Cut with ./build.sh debug and then execute the following command:
examples/termcap | tee /tmp/output ; sed -i -n '/^Terminal/,/`--/p' /tmp/output
Post me the output of cat /tmp/output
Do you also get the libtinfo.so displayed when using the ldd command?
ldd src/.libs/libfinal.so | grep tinfo
libtinfo.so.5 => /lib/x86_64-linux-gnu/libtinfo.so.5 (0x00007fc734d07000)
What does the environment variable $TERM contain?
If all runs correctly, the file /usr/share/terminfo/g/gnome-256color should be used.
Does this file exist on your system?

Screenshot of "ui" (add blinking in your imagination):
That's interesting. I found out that the VTE project has changed the terminal ID from 1 to 65 since version 0.53.0. I have changed the terminal detection in the current commit.
If it doesn't work, please don't put the whole screen output here again. I only need the part from /tmp/output.
You need an operating system enviroment that implements a POSIX system call API. Under Windows this can be realized with the Cygwin project.
Rather than reimplementing Qt, you should strive to provide features, that Qt does not provide. Perhaps web deployment (emscripten has a curses port available) and declarative language support, that compiles into C++. Qt Quick and the associated bloat are a major issue among embedded Qt devs.
I'm not trying to reimplement Qt Framework. The basic class design is influenced from Qt and not a one-to-one Qt clone. A curses library is not required by Final Cut, it has its own cursor optimization and window management. Only a Termcap library with a capability database is required.

Hi!
I'm trying to catch the terminal resize event, but don't know how. My first thought was to subclass FWidget and add a onResize(FResizeEvent *event), but it did not work. In the First Steps you explain that most events will be provided by event() of FObject, but all I see is just a call to onTimer() and onUserEvent(). Is there a simple example available about this?
Thanks in advance.
FObject is the base class of FWidget that implements the onResize() event for terminal resizing. The resize event is a specific case that only sends events to the application object.
Code example:
#include <final/final.h>
using namespace finalcut;
class FApp : public FApplication
{
public:
FApp (const int& _argc, char* _argv[])
: FApplication(_argc, _argv)
{ }
private:
void onResize (FResizeEvent* ev) override
{
FTerm::beep();
FWidget::onResize (ev);
}
};
int main (int argc, char* argv[])
{
FApp app(argc, argv);
FMessageBox mbox(&app);
mbox.setTitlebarText("Listen...");
mbox.setText("Beep on resize.");
mbox.exec();
}
Maybe the method adjustSize() is more what you are looking for:

Hi! I've got another question. Since yesterday I'm struggling with a std::thread. Within a subclass of FDialog I want to fill a FListBox with items read by a thread. The thread is created after instantiation. Well, I started with a simple function that just prints that it's been called. But even this thread causes a segmentation fault on thread.join().
void test() { fprintf(stderr, "Test running\n"); }
// void Module::test() { fprintf(stderr, "Test running\n"); }
void Module::revert() {
std::thread thread_read_communities(test);
if (thread_read_communities.joinable())
thread_read_communities.join();
}
Well, Module::test() fails too. To test it, I tried the following simple code snippet:
class test {
public:
void testfunc() { printf("Thread Running\n"); }
void main() {
std::thread foo(&test::testfunc, this);
foo.join();
}
};
int main(int arc, char **argv) {
test bar{};
bar.main();
exit(0);
}
This snippet works like charm. I'm not used to C++ so I think I'm missing something important here. Does anyone have got an idea?
Thanks in advance.
Unfortunately I don't know your program code, so I can't tell you what could be the reason for the segmentation fault.
This little example might help you:
#include <chrono>
#include <thread>
#include <final/final.h>
using finalcut::FPoint;
using finalcut::FSize;
class ListBoxDialog : public finalcut::FDialog
{
public:
ListBoxDialog (FWidget* parent = nullptr) : FDialog(parent)
{
setText (L"List copy per thread");
setGeometry ( FPoint(int(1 + (parent->getWidth() - 41) / 2), 5)
, FSize(41, 16) );
setShadow();
list1.setGeometry(FPoint(2, 1), FSize(18, 10));
list1.setText ("Source");
list1.insert ( {1, 2, 3, 4, 5, 6, 7, 8} );
list2.setGeometry(FPoint(21, 1), FSize(18, 10));
list2.setText ("Destination");
Quit.setGeometry(FPoint(28, 12), FSize(10, 1));
Quit.setText (L"&Quit");
Quit.addCallback
(
"clicked",
finalcut::getFApplication(),
&finalcut::FApplication::cb_exitApp,
this
);
}
~ListBoxDialog()
{ }
private:
void copy() // run as thread
{
std::this_thread::sleep_for(std::chrono::seconds(2));
for (std::size_t i = 1; i <= list1.getCount(); i++)
list2.insert(list1.getItem(i));
list2.redraw();
updateTerminal();
}
void onShow (finalcut::FShowEvent*)
{
std::thread t1(&ListBoxDialog::copy, this);
t1.detach();
}
finalcut::FListBox list1{this};
finalcut::FListBox list2{this};
finalcut::FButton Quit{this};
};
int main (int argc, char* argv[])
{
finalcut::FApplication app(argc, argv);
ListBoxDialog dlg(&app);
app.setMainWidget(&dlg);
dlg.show();
return app.exec();
}
