I have a nana::group which, inside it has a nana::checkbox and a nana::label.

The label provides a help message for the options in the checkbox. If label is located in the same vertical level as the checkbox option then when I press on label, instead of seeing the message, the checkbox option close to it gets activated. How can I limit the action of checkbox to the horizontal length of the t

The text of combox is left justified. How can I make it centered or right justified?

If there is no method to do this, then I ask Jinhao to add these features to the nana::combox class. Thanks.

I am trying to specify a nana::combox that has several predefined options. I would like to have an option to get a user defined string for this combox. So, I decided to have a nana::checkbox and if this checkbox is checked then I make the combox editable and get the user specified string and add it to the combox options. This idea does not work. The combox remains un-editable. What is wrong here?

Hare Krishna, All!

I have Windows 10, download and install MinGW from into C:\MinGW, download and install CodeBlocks 11979 from,23712.0.html , I followed instruction from . I set also Settings-> Compiler...->Toolchain executable:

I edit item GNU GCC Compi
I still cannot build a simple "hello world" program using nana v1.7.3, even when I build with gcc v8.3

This problem was reported back in August when v1.7.2 broke it.

Here is the program

#include <iostream>
#include <nana>
#include <nana>

using namespace std;

int main()
using namespace nana;
form fm;
label lb(fm, rectangle(fm.size()));

Hi All,
I'm currently learning advanced STL concepts and consider nana as my learning project. Currently focused on how animation works and for that, I have started looking into related classes and methods.

One question I have in my mind is to render BMP image sequences we have to use pushback method of image class but I am unable to create frambuilder example.

How can I use this std:

When you click on a menu choice, the menu will be closed... this is fine. But if it is an option or a highlight, you'd want it remaining open... so that user knows that they choose the right option.

The question then, how to let the menu remaining open after choosing an option?
