jverzani / gtkinteract.jl Goto Github PK

To make a button with a callback utilizes a pattern like

b = button("click me")
window(b)
map(b) do args...
   println("clicked me")
end

All good, but if things get more complicated, the button fails to be lifted:

window(toolbar(b), grow(b))

Now clicking on b does not update the GUI (any of the three instances)

Also directly pushing a value doesn't work, though this will at first:

push!(b.signal, nothing)

Not sure what happens here...

In #10 it was pointed out this is not working. The issue lies in the relationship between Gtk and Reactive and is reported here: JuliaGraphics/Gtk.jl#229

Until that gets sorted out, this package will only work with older commits, such as can be done through Pkg.pin.

I tried with Immerse, inspectDR and Gadfly to add a image in a window with widgets, for example sliders.
When i use the slider i get this error:
MethodError: no methiod matchin update_view.

For example, this code from examples:

w = mainwindow(title="Simple test")
n = slider(1:10, label="n")
m = slider(11:20, label="m")
cg = cairographic()

append!(w, [n, m, cg])

map(n,m) do n,m
  push!(cg, plot(sin, n*pi, m*pi))
end

Can you show me an example. A simple one, for example a plot of a function that changes in real time when you move the slider. It would be nice if you tell me packages versions.

Thanks.

I have a program, which could run for a very long time and generate a lot of pictures associated with different parameters. I want to use GtkInteract to visualize those pictures by

using GtkInteract,ImageView
@manipulate for a=1:10, b=1:10, c=1:10
   img=imread("...")
   view(img)
end

Is it difficult to integrate ImageView into GtkInteract? Or could you suggest other methods to achieve this?

Thanks

I tried the @manipulate example in the README and got the following error:

ERROR: MethodError: `display` has no method matching display(::Gtk.GtkCanvas, ::Winston.FramedPlot)
Closest candidates are:
  display(::AbstractString, ::Any)
  display(::TextDisplay, ::Any)
  display(::MIME{mime}, ::Any)

I was trying to get this package to work with Immerse using the following flow, but had some problems. There may be simpler implementations of this, but I have found none that works with multiple plots and sliders/checkboxes (feel free to give me some pointers if there is). Below follows a toy example:

using GtkInteract, Immerse
k = slider(1:0.1:10)
cg1 = cairographic(width=200,height=150)
w = window(hbox(k,grow(cg1)))
Reactive.preserve(map(k) do k
    fig1 = Immerse.plot(y=(1:10).^k)
    push!(cg1, fig1)
end)
w

The code above doesn't work, but I was able to create a solution.
Would you consider adding the following function to the package? (I can create a pull request, but wanted to know if I'm using the package correctly first)

function Base.push!(obj::CairoGraphic, p::Gadfly.Plot)
    if obj.obj != nothing
      push!(obj.obj, p)
    end
end

The problem that the old image doesn't disappear is still present. This can be easily solved by adding a backgound to the plot:

fig1 = Immerse.plot(y=(1:10).^k, Theme(background_color=Colors.RGB(1.,1.,1.)))

is there a way to generalize this or solve it in some other way?

JuliaGizmos/Reactive.jl#65 was a big (and likely breaking) change that just got merged. Once it gets tagged (CC @shashi), this will likely need updating. I might be able to help, but first some questions:

• Are you interested in registering this sometime? If so, I might use it in GtkUtilities.jl.
• Given the existence of Immerse.jl, what do you think of removing the Winston dependency? I went with Gadfly mostly because it is more actively maintained.

Is this package still being developed?
It doesn't seem to work for me on Fedora 22 with julia 0.4.5. I simply get either a completely black or completely transparent window depending on which window manager I use.
