ReaImGui and shortcut focus

[JLP]

Hello everyone,

I'm working on simple script to show/hide track in MCP and TCP based on their name. For the GUI, I'm using ReaImGui, with a simple text box.

Now, for it to be efficient in a real world situation, it would have to focus the text box with on a shortcut, no matter where the user is focused in the UI.

I've tryied a couple of approches without any success so far. What would you recommand ?

Thank you for your help !

Do you mean a shortcut key to focus the input field from within elsewhere in the window, like this?

package.path = reaper.ImGui_GetBuiltinPath() .. '/?.lua'
local ImGui = require 'imgui' '0.9.3'
local ctx = ImGui.CreateContext('My script')

local function loop()
  local visible, open = ImGui.Begin(ctx, 'My window', true)
  if visible then
    if ImGui.Shortcut(ctx, ImGui.Mod_Ctrl | ImGui.Key_F, ImGui.InputFlags_RouteGlobal | ImGui.InputFlags_RouteOverActive) then
      ImGui.SetKeyboardFocusHere(ctx)
    end
    ImGui.InputText(ctx, 'My input')
    ImGui.End(ctx)
  end
  if open then
    reaper.defer(loop)
  end
end

reaper.defer(loop)

Thank you very much, cfillion, for your answer !

You piece of code seems to work only if I'm focus in an ImGui window. If I'm focus in the arrange view for example, it does not work. I guess it's to be expected, but I was wondering how to build a mecanism to make it possible.

Bellow is a link to a gif to try to show the "issue" better.

For a shortcut from REAPER you'll need a second script bound to a shortcut in the Action List.

Have it send some message to tell the first script it's time to call SetKeyboardFocusHere, for example using SetExtState (with persist=false).

cfillon, thank you for your answer !

So it's kind of working.
The textbox is effectively focused using another script and ExtState, but as the window hosting the script is not focused the keyboard is still redirected to the main window of REAPER.

I'm digging in the API to found something

So just to share my solution on this problem, I've ended up doing this inside my main window function. :

    if reaper.GetExtState("jlp_Track filter", "request_focus") == "true" then
        local window = reaper.JS_Window_Find('Track filter', true)
        reaper.JS_Window_SetFocus(window)
        ImGui.SetKeyboardFocusHere(ctx)
    end

I have an action that set the request_focus to "true", then from the main script, I've only be able to get the window focused using the JS API, because it seems to me that the window focusing function of ReaImGui relates to ReaImGui window (which seems to makes sense now that I'm writting it )

Any way, this piece of code work just fine !

In my script, I have the opposite problem with focus, I don't want it at all. When I click in it I do not want to take focus from the main window. Does anyone know how to solve that?

WindowFlags_NoInputs to have clicks passthrough to the window behind. If you still want to process clicks then, instead of that, give focus back to the main window.
