Method to disable/grey-out widgets?

[IanButterworth]

It seems that disabling/greying-out widgets to prevent user interaction in imgui itself isn't well implemented (see ocornut/imgui#211), but I was wondering whether that functionality is somehow added/addable through CImGui.jl?

Also, thanks for all the work on this package! It's been a delight to work with

I was wondering whether that functionality is somehow added/addable through CImGui.jl?

It looks like this feature is already in ocornut's TODO list, it would be great if it could come into 1.70. Since CImGui.jl is just a wrapper and not able to provide additional internal features like this one, the only feasible way is to manually patch imgui and expose that API like what CImGuiBuilder did here.

Now those internal APIs are supported in CImGui.LibCImGui, so we can implement this on the Julia side:

julia> using CImGui, CImGui.LibCImGui

julia> include(joinpath(pathof(CImGui), "..", "..", "examples", "Renderer.jl"))
Main.Renderer

julia> using .Renderer

julia> Renderer.render(width = 360, height = 480, title = "IMGUI Window") do
           CImGui.CSyntax.@cstatic disabled=false begin
               CImGui.Begin("Hello ImGui")
               CImGui.CSyntax.@c CImGui.Checkbox("Disable", &disabled)
               if disabled
                   igPushItemFlag(ImGuiItemFlags_Disabled, true)
                   CImGui.PushStyleVar(ImGuiStyleVar_Alpha, 0.5)
               end
               CImGui.Button("My Button") && @show "trigger"
               if disabled
                   igPopItemFlag()
                   CImGui.PopStyleVar()
               end
               CImGui.End()
           end
       end

Great! Thanks for the example

I'll close this but if I come across any issues will reopen
