qpcr4vir/nana

a modern C++ GUI library

nana's Issues

edit item in treebox and listbox (optional only)

a format for the entire column or row, not for each cell

The format set for a cell will override the format for the column.
This could be dynamic. We set a function for the column which create dynamically the format for cell.

listbox column get moved after resize

Repeat scrooll page by long mouse click

drag the bar: OK: move the list. Click long the buttons in the bar - not

make more "std::"

container - like objects:
back() and front() for menu & item_proxy & menu_bar, tabbar, combox, listbox & cat_proxy,

refactor all API to use or mimic std , extensions or proposed libraries:
std::filesystem, chrono, 2D drawing, regex, codecvt_utf, atomic, thread, iterator, optional, any
see feature test macros

Whell dont scrooll in textbox, listbox and treebox in secundary monitor

Only occurred in second display !!

textbox select a word by double-click

Use color scheme in scroll

the textbox emit new position of cursor in relation to absolute pos in string of text and in line number, and pos in line

Use CTest to create and run our demos instead of (re)implementing it in travis

statusbar

listbox shrink a group of colummns to fit all in screen

or to fit the text

create a CMake package

This make even more sense now that VS2017 and CLion work easily with cmake

incorrect listbox navigate with cursor when items ordered

How to put text in clipboard?

Improve CI

Examples: travis CI with clang 5 and gcc 7 in Linux and OSX and including Boost.
A book: how to use Travis CI with C++

Create connan package:

See
cnjinhao#283

Conan introduction; OpenAl example, Wt, cli11, zstd

demo: more for widget_show, calculator, notepad and a pure nana filebox (as in linux)

Introduce command to share with menu, toolbar, button and checkbox

• menu vs. toolbar:
  toolbar is a widget, menu - not.
  • menu: hold a plain ptr to an implement which use structures in a drawerbase::menu namespace.
    The later includes a menu_type, menu_item_type, and the enum checks,

			enum class checks
			{
				none,
				option,
				highlight
			};

menu_item_type hold a plain pointer to a menu_type and all the state-data of the item which can be acceded with an item_proxy which hold a pointer to the menu and the position order of the item.
A new item can be added with menu::append or menu::insert.

			enum class tools
			{
				separator,
				button,
				toggle,
				dropdown
			};

• toolbar: the drawer hold a plain pointer to a drawer_impl_type that hold an item_container of toolbar_items. The later hold the state-data.
  A new item can be added with toolbar::append or with item_proxy::dropdown_append.

• Implement/use checks/tools

• create command: a no-widget class, wich state-data useful to set and to share menu, toolbar, button and checkbox

  • title/text, tooltip/status
  • event handler
  • image (a shared type),
  • set/get image
  • checks style
  • flags: enabled, checked

• Make menu and toolbar API similar:

  • prefer item_proxy

In menu:

• no struct arg_menu ?
• menu::append(shared_command)
• menu::insert(shared_command) .
• in menu_type
• in menu_item_type <---- real data here (generalize?)
  • hold a shared_command
  • add constructor that take a shared_command
  • set/get shared_command (to be used by other constructors)
  • really need 'linked'?
• add to item_proxy
  • set/get shared_command (to be used by other constructors)
  • set/get image
  • answerer()
• reuse renderer_interface?
  In toolbar:
• dropdown_item construct take a menu?

update vs package

complete and improve documentation, Wiki, etc

recomended "About" form (powered by nana v1.... tralala with picture)

treebox right-click on tiptooled item (large node titel) not called

Its seems to ignore some times the gaps from a div string ??? not sure

posible optimization in very big listbox

I may have listbox with more than 100 000 items, and I need to sort.
The sort function come in two versions: for text only and for the atached any.objects only. If the second exist for the given header (column) to sort it have preference to be used.
Also, it could be a ref to an array or vector with the actual data, and indexed by the any object or better simple by the index of the item. The real items or item proxys are created only on demand, on the fly, need to be draw, but not when only need to be ordered. To draw we need maximal 20 to 100 items, not more: it is not to much and is not going to be very slow. Drawed items could be conserverd until it go out of the screen.

listbox quick find/show/select items by firs letters in ordered column

update toolbar

set the font for textbox

How to un-set the column ordered marker in the header of a listbox?

listbox export cvs

And then to have a way of switch the entery application from one "style" to other

listbox and treebox - drag-drop items

generalize radio_group into check_group

for check-style buttons, menu items, and toolbar buttons

string place::div() to retrive last div string

Related to that:
conserve beging and end for each field (in the div string), and have a function that return it and another that return the rectangle of a field based on the position in the string.
