Is it possible to resize the window of the exported panel via Lua?

Hello everybody,

I was thinking to add a foldable keyboard to my panel. Similar to what happens in Kontakt for example, where you can see the digital keyboard or decide to hide it, and this resizes the window as well to show it.

I wrote the following code to change the panel height once a button is pressed, and this works fine in Ctrlr for resizing the canvas:

    keys = mod:getValue()

    if keys==1 then
        panel:getPanelEditor():setProperty("uiPanelCanvasRectangle","0 0 820 465",true)
        panel:getPanelEditor():setProperty("uiViewPortMinHeight",465,true)
        panel:getPanelEditor():setProperty("uiViewPortMaxHeight",698,true)
    elseif keys==0 then
        panel:getPanelEditor():setProperty("uiPanelCanvasRectangle","0 0 820 380",true)
        panel:getPanelEditor():setProperty("uiViewPortMinHeight",380,true)
        panel:getPanelEditor():setProperty("uiViewPortMaxHeight",570,true)
    end


end

However on the exported instance, this does not change the size of the window, so when the keyboard disappears, and the canvas height is changed, there is a big empty part with the background colour.

Is there a way in Lua to resize the window? I searched online and it says it is possible if using a windows manager like "awesome-wm", however I'm not sure if this applies to Ctrlr. Is anybody aware if this is possible?
Otherwise no wahala, I'll just keep the digital keyboard always present :)

There is no way to resize the app window container from LUA. The only thing that is going to change is the inner canvas size.
You can play with the canvas size, it would require to close the ctrlr instance as VST/AU plugins only and display it again to refresh.
Resizing with dragging the corner window will pass the window size for scalable UI but at this point you cannot change the container shape with code like Arturia's plugin showing keyboard or tutorial hints on the right etc.
I don't know how I could implement this. I'll think about it but the way ctrlr is done is one-way at this level.

Yeah that is what I thought. It is perfectly ok, thank you very much I just wanted to know if it was possible in the first place. i guess the discussion is now useful for any other people who where wondering the same thing.

I will look at a way to pass width and height to the top level container but if I remember it was crashing ctrlr. I will post here for further info ;)
