Hi,

I'm attempting to write a small setup application, in the style of Windows 95 Setup, and I'm wondering if aligning panels similarly to the way it does during setup would be a thing I could do here.

e.g.

This is neat as all crap, by the way!

Hi, I just noticed this, apologies for the flurry of tickets.

Anyway, I was wondering if it was possible to change(?) the default UI style to be more in-line with VBDOS?

Thanks!

e.g.

I have two minor compilation problems with finalcut

1. "fobject.h" includes "final/emptyfstring.h", but "emptyfstring.h" is not copied by default with "make install" command.
2. In the source code "register" word is used, but:
   warning: ISO C++1z does not allow ‘register’ storage class specifier

I have been playing with the FListView widget this morning and it looks extremely helpful for our particular use case where we have use case to print nested tabular data (similar to treeview example). Currently, I don't see a easy way to click on a column and possibly sort based on it's values; I see that FListView directly interacts with strings so it may not be able to sort numerical data but even if the library was able to provide a generic callback for clicked-column I should probably be able to handle it in client code; possible swap FListViewItem inplace without creating new objects; maybe something like
std::sort(itemlist.begin(), itemlist.end(), sort_fn); would probably need to additionally do a static_cast<FListViewItem*>() and then possible lookup client data based on 1st column to get new position.

bool sort_fn(FObject* a, FObject* b) {
  auto* x = static_cast<FListViewItem*>(a);
  auto* y = static_cast<FListViewItem*>(b);
  auto& name_x = x->getText(0);
  auto& name_y = x->getText(1);
  // Get saved data from client code which has correct data-types
  auto& x_struct = data_map[name_x];
  auto& y_struct = data_map[name_y];
  return x_struct.temperature < y_struct.temparature;
}

I suggest to enhance a bit FListBoxItem class by passing a user provided data pointer to the constructor.

Change (I just picked up one of the three available constructors):
explicit FListBoxItem (const std::string&);
To
explicit FListBoxItem (const std::string&,const void *data=0);
Store 'data' attribute in FListBoxItem and provide access method to it.

The introduction of data will simplify the use of FListBox class. Consider the following example. There is a custom list std::vector<MyData> mydata;. A programmer wants a UI to select an item in the list and pass it to a function void myfunction(const MyData &data);. To achive this, the programmer has to:

1. Create FListBox object
2. Loop over mydata vector and create string presentations if every MyData item
3. When user selects an item, the code will access FListBoxItem, which has (a) item "string" value and (b) item number
4. One should look back to the original mydata vector (which means the programmer has to keep the container it in the UI code) to access the selected MyData object.

With the proposed modification, the step (4) will not be needed. Think about situations when the original container is not vector, but list or map. In this case "item number" is more-or-less useless, and extra code should be written to keep the items connection.

Trying to do make (as told by README).

I am using the C++ based WebToolKit to build a web server. I would like to provide a virtual console within the solution.

Is there a mechanism for capturing FTermBuffer or FPutChar or similar to capture the results for remove viewing and interaction?

I'd like to submit finalcut to openSUSE for inclusion, but when building it on OBS I see this warning:

libfinal0.x86_64: W: shared-lib-calls-exit /usr/lib64/libfinal.so.0.5.0 exit@GLIBC_2.2.5
This library package calls exit() or _exit(), probably in a non-fork()
context. Doing so from a library is strongly discouraged - when a library
function calls exit(), it prevents the calling program from handling the
error, reporting it to the user, closing files properly, and cleaning up any
state that the program has. It is preferred for the library to return an
actual error code and let the calling program decide how to handle the
situation.

I get the following build failure for finalcut on openSUSE Tumbleweed:

I assume some library/compiler/toolchain was updated on oS TW.

i'd like to remove the red lines

didn't find this in the docs

if there isn't, i wonder why, because we can remove shadows no problem

I wanna a menú can change every widgets in the sceeen for others

1. I am having a little difficulty trying to understand the memory-model; particularly with local / member variables. Say, I create 2 FDialog's diag1 & diag2 and 1 FLabel. Now, based on a click event I change the parent window of FLabel from diag1 to diag2 and vice-versa. My code looks something like this:

FLabel label;
FDialog diag1(fapp), diag2(fapp);
diag1.addChild(label);

// And in some callback I do
diag2.addChild(label);

All is expected to work fine till now. However, if I destruct diag1 or diag2 then it'll also try to destruct FLabel; at this point am I expected to see a memory corruption / seg-fault given that FLabel is on the stack and not heap. Overall, I am having a little difficult with the memory-model; should I always construct stuff on the heap or there a different way to think about the memory-model ?

2. Small point but when I have multiple dialog windows; closing any of them creates a confirmation dialog that says do you want to quit the program but in the end it'll only close the window. If I always operate on multiple dialogs what's the correct way to either override this message so it says close window OR correct way to always make it close the complete app ?

    void onClose(FCloseEvent* ev) {
      FApplication::closeConfirmationDialog(this, ev);
    }

3. Dynamic Widgets: I am trying to work with the scrollview.cpp example to make it resizable. I am able to get quite far but I want to understand the different functions a little better. The process I'm following based on the dynamic layout (size-adjustment.cpp) is as follows; is this correct ? I'm going to have a few different types of dialog boxes that will have a dynamic layout so I plan to follow the same convention for all of them ?

    # Override these 3 functions
    void setSize(const FSize& size, bool adjust) override;
    void adjustSize() override;
    void draw() override;

# This code is always fixed; just copy/paste it
void Scrollviewdemo::setSize(const FSize& size, bool adjust) {
  // Calling super class methods setSize() + adjustSize()
  FDialog::setSize (size, false);
  FDialog::adjustSize();
}

# Here, call the base class version and change the widget size if required
void Scrollviewdemo::adjustSize() {
  FDialog::adjustSize();
  // Change widget size (centerDialog())
}

# Here, adjustWidgets() and then call base class function
void Scrollviewdemo::draw() {
  adjustWidgets();
  // Calling super class method draw()
  FDialog::draw();
}

4. I played around the scrollview.cpp (making it dynamic) and menu.cpp and merged the 2 examples. It is working fine in terms of functionality but when I exit the app it screws up the terminal; the cursor disappears and new line is skipped too. Please advise if you can spot the issue. Also, any general advise based on this code. Please see attached code.

Hi , I wanted to make it possibly to redirect the output of a file to a "QuickForm" to simply edit some fields. but it is like cin does not close really well.

so for e.g. : cat test.data | ./quickform -> this shows the fields but when i type on the keyboard I see my input on the form which shouldn't unless a field is selected.

When I try it with a file the read it works fine
So ./quickform test.data
does work

here is my code :

#include <final/final.h>
#include <regex>
#include <string>
#include <fstream>
#include <iostream>

using namespace finalcut;

//		explicit QuickForm (FWidget* parent = nullptr) : FDialog(parent)
    		{

			this->setText("QuickForm");
			this->setGeometry (FPoint(1, 1), FSize(50, 40));
			this->quit_btn.setGeometry (FPoint((this->getWidth()/2-5),(this->getHeight()-3)), FSize(10, 1));
			this->next_btn.setGeometry (FPoint((9),3), FSize(3, 1));
			this->prev_btn.setGeometry (FPoint((5),3), FSize(3, 1));
//			std::vector<std::string> data { "The Quick", "Brown Fox" };
			this->records_vctr = data;
			for (int i=0;i<data.size();i++)
				std::cerr<<data[i]<<i<<"object\n";

		field->setGeometry(FPoint(9,(i*3+20)),FSize(20,1));
		field->setLabelText(record[i]);
		field->redraw();
		this->Fields_vctr.push_back(field);
			}
	
	this->redraw();
	this->show();
	
	}
};

	{

		std::vector<std::string>v {};
		while(std::getline(in,line))
			{
			 v.push_back(line);
			}
		return v;
	}
std::vector<std::string> processparameters(const int& argc, char** argv)
	{
	if( argc > 1)
		{
				std::ifstream ifile(argv[1]);
			if (ifile)
				{
				 return readData(ifile);
				}
			else 
				{
				//deal with file errors
				}
		}
	return readData(std::cin);
	
	}

int main (int argc, char* argv[])
{
	std::vector<std::string> v {};
	v = processparameters(argc,argv); for (int i=0;i<v.size();i++) std::cerr<<v[i]<<i<<"vector\n";
	argc = 0;
	argv = nullptr;
	std::cin.clear();
	fflush(stdin);
	FApplication app(argc, argv);
	QuickForm dialog(&app,v);
	app.setMainWidget(&dialog);
	dialog.show();
	return app.exec();
}

If you could point me in a direction would be nice.
Kind regards,

Better yet, try -fsanitize=address,undefined I'd paste them here, but my terminal window freezes when executing my app.

EDIT: I now remember the reason why I didn't want to use tvision anymore was, that the sanitizer went ballistic with it too. It had memory leaks and undefined behavior.

It's a minor warning, but I thought you should know.

Currently, I am running a very basic FApplication which has a number of FDialog's. However, I would like to build something that has multiple Tabs on the top and within each Tab a number of FDialog's. Please suggest a way to accomplish this.

Also, really appreciate the effort you have put in this library. I have found it useful for some of my use cases.

Hi! trying to generate Makefiles with Cywing, after use "autoreconf --install --force" I get the error:

error: AC_CONFIG_MACRO_DIRS([m4]) conflicts with ACLOCAL_AMFLAGS=-. m4

Similar to issue #48, I'm looking to change the box surrounding to an empty space (" ") character. Is there any "good" way to do this (e.g. remove the visual border, but keep its padding)?

After today update from git the mouse is not initialized and is not active. Tested on Fedora Core 31.

The assertion is triggered in the code below. This is really nasty :(

    std::string s1="abc";
    FString s2=s1;
    std::string s3=s2.toString();
    assert(s1==s3);

I've been using this library for a while now and I'm really impressed with it.
I have and option in my ListView to open the bash from the app, when the user clicks the bash option the following function is called

void MainDialog::startBash() { system("cd; clear; reset; sudo bash"); }
now when when I type "exit" I lose focus and can't do any navigation.
is there a way to restore focus to the app after executing these commands ?.

Configuration was fine, but 'make' returns:
....../finalcut/missing: line 81: aclocal-1.14: command not found
And my system does have aclocal-1.15

Hi, it's me again.
Thanks again for resolving the std::cin problem.
But now I have the following problem
if I do : finalcutdemo > file.txt
I don't see my finalcut window appear.
if I close the stdout like with the stdinput I see my finalcut program. but I cannot get the output the be written to the file.txt. I should be able to reattach the stdoutput.
Or to make only the finalcut windows appear to tty.
Do you have an idea ?

kind regard,
Wim Stockman

Thank you very much for this cool collection of widgets. They do look much more awesome than the ancient libnewt. I successfully compiled libfinalcut and the examples in test directory. Everything runs perfectly in x86_64 linux environment.

However, on the armhf Debian on my tablet, the whole library as well as all examples compiled nicely but all the executable gave "cqBus error". I am wondering if there is anything in the source code restricted to x86_64/i386 archs.

Maybe it is too greedy to ask for ARM support at the moment. :)

Hello dear team,
I am trying to integrate this project into an existing CMake based project.
Before I spend more time on this, is there an existing migration that someone did?

Many thanks.

• go to 'examples' directory
• run ./windows (or .libs/windows)
• in the 'windows' application I click "Create", "Quit", "Yes" (to confirm the quit)

On the program exit I receive "Bus error".

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?!

Thank @gansm for this cool console widget library!

I am trying to compile on Mac OS X, and get the following errors possibly due to the missing of gpm library on Mac. Is there any way to fix quickly? Otherwise, is there any plan for support macOS?

In other words, support for different text resolutions?

Im following along with the color themes tutorial and im having a bit of trouble getting it to work.

I've noticed a significant decrease in performance after the update. Is it something that you plan on improving as 0.70 gets closer to release?

Button shadows display weird in Konsole, Alacritty and several other terminal emulators. Alacritty simply displays squares for all of the UI characters.

Consider the following code. It works fine with short (less than terminal window width) strings, and crashes with long.

#include "final.h"

int main (int argc, char* argv[])
{
    if( argc!=2 )
        return 1;
    FApplication app(argc,argv);
    FMessageBox info ( "Greeting",argv[1], FMessageBox::Ok, 0, 0, &app );
    info.show();
    return 0;
}

It's Windows' terminal capable tu use some of the xterm-256color features?
I ran term-attributes.exe but the next features don't seems to works:

• Double underline
• Crossed-out
• Blink
• Invisible
• Protected

I've successfully compiled and installed finalcut:

$ ls /usr/lib/libfinal*
/usr/lib/libfinal.a  /usr/lib/libfinal.la  /usr/lib/libfinal.so  /usr/lib/libfinal.so.0  /usr/lib/libfinal.so.0.6.1

$ sudo /sbin/ldconfig -p | grep final
	libfinal.so.0 (libc6,x86-64) => /lib/libfinal.so.0
	libfinal.so (libc6,x86-64) => /lib/libfinal.so

but when I compile the dialog.cpp example I get this:

Hello, was experimenting with finalcut (already a huge fan, absolutely brilliant work) and found setMaximumWidth , setMaximumSize, etc. don't see to be obeyed when updating a label's text dynamically. Here's a minimal reproduction case for my scenario below.

The output looks something like the screenshot attached, with dots wrapping line after line.
If you uncomment the commented two lines, I noticed it would enforce the minimum size as the maximum, and only 5 dots were displayed. Also to note, if I use FLabel::setGeometry or setSize, the maximum size is enforced, and no wrapping occurs.

Perhaps I am not using FLabel the way it was intended, but as a newcomer it seems like this is probably not intended and maximum hints should be enforced. Or maybe I made a simple mistake?

Thanks!

#include <iostream>

#include <final/final.h>

namespace fc = finalcut;

class HelloDialog : public fc::FDialog
{
	fc::FLabel labelDim{this};

public:
	HelloDialog(fc::FWidget& widget)
		: FDialog(&widget)
	{
		setText("Hello Finalcut - Size Issue");
		setPos(fc::FPoint(10, 1));
		setSize(fc::FSize(50,25));

		//labelDim.setMinimumSize({5,1});
		labelDim.setMaximumSize(30, 1);
		labelDim.setMaximumHeight({30,1});

		addTimer(100);
	}

	void onTimer (fc::FTimerEvent *ev) override
	{
		labelDim.getText() << ".";

		//adjustSize();

		redraw();
	}
};

int main(int argc, char **argv)
{
	fc::FApplication app{argc, argv};
	HelloDialog dialog{app};
	dialog.show();

	app.setMainWidget(&dialog);

	return app.exec();
}

I want to compile this with my application... how do I do that? I can't include the CPP files, nor can I act like final.h (define USE_FINAL_H, symlink src/include/final to src/final and include the C++ files in the same order)...

After I opened file "fstab", then any action in related windows is finished by segfault.
