me: If we want this to be a gui program, what options do we have in Nim?
Nim has several options for creating GUI programs. Here are some of the most
popular ones:
> NimQT - a binding for the Qt GUI framework.
>
> Nimx - a widget toolkit for creating GUIs.
>
> GTK+ bindings for Nim - a binding for the GTK+ GUI toolkit.
>
> Nimgl - a binding for the OpenGL graphics API.
>
> Nuklear - a small, efficient, immediate-mode UI library.
>
> WxWidgets bindings for Nim - a binding for the cross-platform GUI toolkit.
>
> Electron-nim - a Nim wrapper for Electron, which allows you to create desktop
> applications using web technologies.
You can choose the one that best fits your needs and experience with GUI
programming.
me: show me an example winzip graphics interface (for just one window) with the
nuklear library
Sure, here's an example GUI program using the Nuklear library for a single
window WinZip-like interface:
import nuklear
proc main() =
# Initialize Nuklear context
var ctx = initNuklear()
# Define window properties
const WIN_WIDTH = 640
const WIN_HEIGHT = 480
const WIN_FLAGS = nk_window_flags.NK_WINDOW_BORDER or
nk_window_flags.NK_WINDOW_MOVABLE or nk_window_flags.NK_WINDOW_CLOSABLE or
nk_window_flags.NK_WINDOW_TITLE
# Start GUI loop
while true:
# Poll events and update GUI
nk_input_begin(ctx)
while true:
event = pollEvent()
break if event.type == nk_evt_type.NK_NONE
handleEvent(ctx, event)
nk_input_end(ctx)
# Begin GUI layout
if nk_begin(ctx, "WinZip", nk_rect(100, 100, WIN_WIDTH, WIN_HEIGHT),
WIN_FLAGS):
nk_layout_row_dynamic(ctx, 30, 2)
if nk_button_label(ctx, "Compress"):
# TODO: Handle compression
echo "Compression button pressed"
if nk_button_label(ctx, "Decompress"):
# TODO: Handle decompression
echo "Decompression button pressed"
# End GUI layout
nk_end(ctx)
# Render GUI
nk_render(ctx)
# Shutdown Nuklear context
shutdownNuklear(ctx)
when isMainModule:
main()
Run
This example creates a single window with two buttons for compression and
decompression. When the buttons are pressed, the program will output a message
to the console. You can replace the echo statements with the appropriate
compression and decompression code using the functions we defined earlier.
