Nana v1.7.3 fails to build with g++ v5.1, which is the standard compiler with code::blocks release. Upgrading the compiler to v8.3 allows nana to build. Note that upgrading the code::blocks compiler is an advanced task.

The nana downloads page says it will build with "Any Standard C++ compiler(Visual C++ 2013, GCC/MinGW and Clang)". This is false.

Here is v5.1 error:

A few months ego I guessed that NANA is dead. Today, that comment is not a guess and is a reality. The main developer of the NANA has disappeared!!! and no longer continue developing the library.

Some of the more experienced users of NANA, like Error Flynn is trying to help and keep the hope alive by finding the bugs and write a fix for them. But, I think his efforts and other good people

It has been almost two years that I started to learn NANA for developing the GUI for my applications. It was a challenging and interesting experience for me. I was very excited that I am learning a library that soon would be a rival to Qt and wxWidgets, but unfortunately the pace of development of NANA and its awful documentation made me very disappointed.

Recently I noticed that the main d

Nana should have its centralized place to contribute to documentation? Yes :d
I have created a html documentation "template" for Nana in GitHub for everyone to contribute to it. You can clone the repository and start adding new pages and changes.

Examine nana-button.html to understand how the class "accordion" and the class "panel" work.

The structure is

From the blog:

The really important part is the API (the design of the global structure, main classes and functions)

So, maybe, there should be some discussion about this?

The first thing that hits me when I look at nana's API design is the large numbers of things that serve almost the same purpose but are not quite identical. This really clutters up the design and makes nana hard

The Goal and the goals of nana. : I just added this nana blog. Jinhao added this text some months ago on the wiki, with the intention of getting people helping to improve it. But I afraid it have not a good visibility there.
I hope it will help people understand a few things, and that it will be improved.
(you can just improve the wiki, and I will port it back)

Yeah, the Winter is coming) (or Q- What does it mean), and we need to be prepared.
This will be a post blog I'm thinking about. The reason is that a new major version of the c++ standard is a great opportunity for all of us to improve our programming experience, but it is also a lot of work as library maintainer and tester.
Nana already has experience with this: the c++03 version was maint

Hi, I am using gcc-7.3.0 (provided with qt-5.13.1). When i try use nana-1.7.2 then there is a lot of linking problems with filesystem, either when i use nana or std filesystem. All of them are related with filebox and filesystem units.

I remember a few months back, after a few exchange of messages, Jinhao agreed to cleanup the NANA classes and method's name and their arguments in version 1.8.

I am wondering if this is still on?

For example:

if a class is called "Sort", it would be nice to have the methods like this:

Hi All,

I'm working on a new project and I would like to create a customizable layout where the user can show/hide, arrange, move, resize, etc ... several panels.
As reference example think to the MS Visual Studio editor.

I've worked a little with the DOCK field and it seems to be a good start but not yet complete.

Is there someone who use the DOCK field? If yes, what are your impr

I'm trying to compile nana-creator for linux. I downloaded the project and it includes a build/codeblocks_linux folder.

I opened that project and when I gave it to compile I get the following errors:

Running the following simple demo and dragging the splitter bar to left (or right) close to the edge cause a crash due to the dock caption text renderer function

Nana does not provide an arc drawing primitive, so we have to use the windows API directly. Something like this:

#include <cmath>
#include <nana/gui.hpp>

#include <windows.h>

/** Draw Arc of circle
@param[in] graph context
@param[in] x for conter, pixels 0 at left of window
@param[in] y for center, pixels 0 at top of window
@param[in] r radius, pixels

I need to make a function which open new form. In this form need to use mouse event and change label caption. Need this form to open many times.

bool openHold() {
using namespace nana::gui;

form fm(nana::rectangle(20, 20, 300, 300));
fm.caption(L"Hello World");

static label lm(fm);
lm.caption(L"Hello, world!");
button change(fm), quit(fm);

I want to build a program with system tray. For this I used WINAPI WinMain

When I close the program using LRESULT CALLBACK WindowProcedure I get this error: Nana.Gui detects a memory leaks in window_manager, 2 windows are not uninstalled

I try nana::API::exitall() but get error: 'exitall' : is not a member of 'nana::gui::API
