Julia Package for UI development

Hi everyone,

I want to develop a GUI written in Julia, with the following requirements:
Widgets: top menu, tabs, checkboxes, radio button, range sliders, text-fields
Widgets state: enabled/disabled, hidden/unhidden

I need your advice about the best Julia package to develop my GUI (preferable web-based but can also be desktop-based).

Thank you so much,
Sara

Hey Sara, welcome.

Check out this article I wrote: 6 Julia Frameworks to Create Desktop GUI’s and Web Apps | by Logan Kilpatrick | Towards Data Science

I suggest also checking out:

I am probably missing a few but this is at least the start of where you should look. There are tons of tradeoffs for each so the right one depends on your use case.

Here is a quick example using Gtk.jl and GtkReactive.jl . This is desktop based. Please keep in mind that if you use Gtk on Windows, your REPL will become a bit sluggish:

using Gtk
using Gtk.ShortNames, GtkReactive

# Init GUI objects
win     = GtkWindow("GUI", 600, 600);
g       = GtkGrid();
c       = canvas(UserUnit,400,400);
# Text label
label   = GtkLabel("Welcome")
# Buttons
b1  = GtkButton("B1");
b2  = GtkButton("B2");
b3  = GtkButton("Fill");
b4  = GtkButton("B4");
b5  = GtkButton("B5");

# Dropdown menu with labels
c_b     = GtkComboBoxText();
push!(c_b,"none");
for x in ["apples","oranges","blah"]
    push!(c_b,x)
end
set_gtk_property!(c_b,:active,1);#set the active element

# Set layout
g[1:2,1] = label;   # Cartesian coordinates, g[x,y]
g[1,2] = b1;
g[2,2] = b2;
g[1,3] = b4;
g[2,3] = b5;
g[1,4] = b3;
g[2,4] = c_b;
g[1:2,5] = c;
set_gtk_property!(g, :column_homogeneous, true);
set_gtk_property!(g, :column_spacing, 15);  # introduce a 15-pixel gap between columns
# Build and show
push!(win, g);
showall(win);

# Callbacks
function btn_1(w1)
	println("button 1 pressed")
end
signal_connect(btn_1, b1, "clicked")

function btn_2(w2)
	println("button 2 pressed")
end
signal_connect(btn_2, b2, "clicked")

function btn_3(w3)
	@guarded draw(c) do widget
    ctx = getgc(c)
    h = height(c)
    w = width(c)
    # Paint red rectangle
    rectangle(ctx, 0, 0, w, h/2)
    set_source_rgb(ctx, 1, 0, 0)
    fill(ctx)
    # Paint blue rectangle
    rectangle(ctx, 0, 3h/4, w, h/4)
    set_source_rgb(ctx, 0, 0, 1)
    fill(ctx)
	end
	show(c);
end
signal_connect(btn_3, b3, "clicked")

function btn_4(w4)
    GAccessor.text(label,"this button does something")
end
signal_connect(btn_4, b4, "clicked")

function btn_5(w5)
    # get text
    txt_from_dropdown = Gtk.bytestring(GAccessor.active_text(c_b))
    GAccessor.text(label,"you selected:"*txt_from_dropdown)
end
signal_connect(btn_5, b5, "clicked")

There is also GitHub - Gnimuc/CImGui.jl: Julia wrapper for cimgui, for hardcore stuff.
