Anyway something I've noticed after playing with LICE,GDI etc last 20 days.

Sometimes one bitmap renders over others and sometimes below. I'm not sure why is that happening. You can see that in my last post here regarding touchscreen:
You can see that "menu" highlight bitmap is behind main one, but one of 30 times it will get rendered above it. Is there any control over it or the code just needs to be:
first - second - last regarding drawing?

EDIT: Just as I've try to test something it appeared

You can see that last one menu highlight is rendered above everything along with its background

ATM there is no control over the order in which linked bitmaps get drawn on the screen.

Hey Julian,

Something in the latest dev build 521 - causes reaper to hard crash when I run some of my scripts which use your API.

I remove your extension dll - and although my scripts lose some functionality - they work ok again.

I'm generally using Mouse and Window functions - some GDI functions (and load mouse cursor - but still crashed when I removed this).

Trying to narrow down the problem...

EDIT:

Strangely - it seems to be your JS_ReaScriptAPI_Version() function which is crashing Reaper.

Would it be to much to ask for an API to set global project startup actions. It would work similar to SWS/S&M: Set global startup action but it would get called on every project load.

I know we can create project templates with SWS/S&M: Set project startup action, but that doesn't always really work

This is indeed strange. What OS and REAPER version are you using?

Does even a single-line script "v = reaper.JS_ReaScript_Version()" crash your system?

Yeah- I went through all the commands I use in Stripper in a separate Lua file - and the version API was the cause.

I'm on windows 10 64bit - latest dev build of Reaper - dev521

This crash was reported to me by Stevie - so it's not just me.

The latest dev build has this:

Code:
+ API: support optional arguments in extension-supplied functions when called from ReaScript/Lua [t=219455]
which might be the cause?

Julian I have small issue that i cannot figure out how to fix so if you can please assist:
Image of the item is not shrinking/stretching it just reveal its content and disappears when its off the original.



Drawing code
Code:
for j = 1, #tbl.info[i].items do
            local as_item = tbl.info[i].items[j]
            local item_bm = item_ghosts[as_item].bm
            local item_start, item_lenght = item_blit(as_item, tbl.time_start, tbl.time_end, pos)
            reaper.JS_Composite(track_window, 
                      math.ceil(item_start * zoom_lvl) - Arr_pixel, -- X
                      item_t - y_view_start + item_bar,             -- Y
                      math.ceil(item_lenght * zoom_lvl),            -- W
                      item_h,                                       -- H
                      item_bm,                                      
                       0,                                           --x
                       0,                                           --y
                       math.ceil((item_lenght * zoom_lvl)),         --w
                       item_h)                                      --h
          end
grabbing code
Code:
for j = 1, #tbl.info[i].items do
        
        local as_tr, as_item  = tbl.info[i].track, tbl.info[i].items[j]
        local item_t, item_h, item_b = TBH[as_tr].t, TBH[as_tr].h, TBH[as_tr].b
        local item_bar = (item_h > 42) and 15 or 0
        local item_start, item_lenght = item_blit(as_item, tbl.time_start, tbl.time_end)
        
        local bm = reaper.JS_LICE_CreateBitmap(true, math.ceil(item_lenght * zoom_lvl), item_h)
        local dc = reaper.JS_LICE_GetDC(bm)
        
        reaper.JS_GDI_Blit(dc, 0, 0, track_window_dc,                                -- SOURCE - DESTINATION
                            math.floor(item_start    * zoom_lvl) - Arr_pixel,        -- X
                                      ((item_t       + item_bar) - y_view_start),    -- Y
                            math.ceil(item_lenght   * zoom_lvl),                    -- W
                                       item_h - 19)                                  -- H (-19 TO COMPENSATE ITEM BAR REMOVING)
      
        item_ghosts[as_item] =  {bm =  bm , dc = dc }
      end

At first glance, this drawing code might be the problem:
Code:
            reaper.JS_Composite(track_window, 
                      math.ceil(item_start * zoom_lvl) - Arr_pixel, -- X
                      item_t - y_view_start + item_bar,             -- Y
                      math.ceil(item_lenght * zoom_lvl),            -- W
                      item_h,                                       -- H
                      item_bm,                                      
                       0,                                           --x
                       0,                                           --y
                       math.ceil((item_lenght * zoom_lvl)),         --w
                       item_h)                                      --h
          end
The last --w and --h lines probably cut off part of the bitmap. To shrink and expand the ghost, the entire source bitmap must be composited, so (source w and h remain constant), and only the image size W and H in the track window changes.

Yeah thats whats happening, so the last two should be zero or I need to store original sizes also ? Probably second one

You will need to store the original size.

The code from my own scripts above is probably the best example I can give.

Depending on exactly which keys you would like to include or exclude, you may need a combination of GetState and GetDown or GetUp:

In case of "press and hold" functions that run as long as the key is held down, use GetState to get the currently active keys. To include the shortcut keys that were used to call the scripts, use GetState(startTimeOfScript-1).

To get keys that were newly pressed, I use a combination of GetState and GetDown: GetDown(prevCycleTime) gets KEYDOWNs since the last defer cycle, and then compares it against GetState(startTime-1) from the *previous* defer cycle (which was called at prevCycleTime), to exclude repeated KEYDOWNs that are being sent by keys that were already down in the previous cycle.

Hey, thanks man!

He firsts creates this static variable:
https://github.com/reaper-oss/sws/bl....cpp#L421-L422

The he registers it on reaper startup:
https://github.com/reaper-oss/sws/bl....cpp#L430-L431

And then during every project save/load these 3 functions get called by REAPER:
https://github.com/reaper-oss/sws/bl....cpp#L391-L419

And in those functions you check if there's anything you would like to run during that time. In global project action case, you simply read the action in question during extension load and run it in ProcessExtensionLine.

The timer he is using is just to postpone running the action until the whole project loads (at least I think...I do remember these updates and I remember we had some trouble until we used the timer trick...I think it's the same thing as doing defer() from .lua script )

So instead of just doing Main_OnCommand(cmdId, 0) - he registers a timer:
https://github.com/reaper-oss/sws/bl....cpp#L401-L402

And then deregisters that same timer from itself and calls Main_OnCommand(cmdId, 0) there:
https://github.com/reaper-oss/sws/bl....cpp#L224-L236

And also makes sure timer gets deregistered properly on REAPER exit (not sure if this actually might be necessary because timer deregisters itself, but it's good practice anyway and we always strived to make sure everything deregistered properly during REAPER exit):
https://github.com/reaper-oss/sws/bl....cpp#L436-L437

If you got any specific question, feel free to ask. While working on SWS, both Jeffos and myself met with a lot of small quirks like this one (registering a timer like this)...SWS is like a small encyclopedia on how to deal with a lot of small idiosyncrasies inherent to REAPER This is the exact reason I was always for unification of C++ extensions and was afraid SWS will go to hell if people start doing their own extensions instead of contributing directly to SWS...


Regarding contributing - I actually wouldn't mind contributing but I just can't find the time to go through the whole visual studio setup etc...I had a lot of work on setting things up since I got back to REAPER and now I'm in the middle of writing an album.

I must confess that after writing countless scripts these days, I do miss C++. Who knows, when I finish this period of life, I just might give it another round. No promises, lol - who knows where this music making will take me ;D

No, no...it works! But the problem is that you have to set up project action for every project you want it to use. There's currently no known way to have REAPER run something on EVERY project load without setting the project up.

That's why I tried to differentiate between PROJECT action and GLOBAL PROJECT action when describing the issue. I remember actually wanting to add that, but that being Jeffos part of code, I just hoped he would add it. And then he abruptly left and I had a breakdown and switched to Cubase and then abandoned music all together until now

osX users have trouble with

Code:
local _, scroll, _, _, _ = reaper.JS_Window_GetScrollInfo(track_window, "SB_VERT")
SInce by API it expects string what can I do about this?

And while we are at it I also have

Code:
local mixer_wnd = reaper.JS_Window_Find("mixer", true)   -- DONT KNOW ITS ID

local track = reaper.JS_Window_GetLongPtr(handl, "USER") -- DONT KNOW HOW OTHER PLATFORMS SEE THIS

local window = reaper.JS_Window_GetRelated(track_window, "NEXT")

reaper.JS_Window_GetRelated(window, "CHILD")

reaper.JS_Window_GetLongPtr(window, "USERDATA")
I know mixer will be a problem with other platforms but do not know how to convert it to ID. This other strings also I'm not sure if they will pass on other platforms but I dont know how to fix it

deeb's error report refers to argument 1, the void*. This is because the line to get track_window uses Window_Find:
Code:
local track_window = reaper.JS_Window_Find("trackview", true) -- GET TRACK VIEW
For cross-platform usage, you should rather use ID (check out Mespotine's long list above):
Code:
local track_window = reaper.JS_Window_FindChildByID(main_wnd, 1000)

I would recommend caution when using GetRelated(hwnd, "NEXT"), since it might not always get the same sequence of windows. Even stuff such as presence of docks or other child windows may change the sequence.

Regarding cross-platform testing, please see PM.

function with "NEXT" is the most important function in the script I do not know how to refactor this if its problematic, but I did not encountered any problem with it yet

Code:
local function GetTrackFromMouseRange(t, b)
  if l_r_t ~= t or l_r_b ~= b then                                                  -- GET TRACKS ONLY IF MOUSE RANGE CHANGED
    local range_tracks = {}
    local trackview_window
    local _, _, arr_top = reaper.JS_Window_GetRect(track_window)
    local window = reaper.JS_Window_GetRelated(track_window, "NEXT")
    while window do
      local _, _, top = reaper.JS_Window_GetRect(window)
      if top == arr_top then trackview_window = reaper.JS_Window_GetRelated(window, "CHILD") end
      window = reaper.JS_Window_GetRelated(window, "NEXT")
    end 
      -- loop over track and envelope windows 
    local window = reaper.JS_Window_GetRelated(trackview_window, "CHILD")
    while window do
      if reaper.JS_Window_IsVisible(window) then
        -- windows visible in arrange view only
        local _, _, top, _, bottom = reaper.JS_Window_GetRect(window)
        if top >= t and bottom <= b then -- IF TRACK IS IN THE MOUSE ZONE RANGE 
          local pointer = reaper.JS_Window_GetLongPtr(window, "USERDATA")
          if reaper.ValidatePtr(pointer, "MediaTrack*") then
            if not Has_val(range_tracks, pointer) then range_tracks[#range_tracks+1] = {track = pointer} end -- ADD TRACKS TO TABLE IF THEY ARE NOT ALREADY THERE
          elseif  reaper.ValidatePtr(pointer, "TrackEnvelope*") then
            if not Has_val(range_tracks, pointer) then range_tracks[#range_tracks+1] = {track = pointer} end
          end
        end
      end
    window = reaper.JS_Window_GetRelated(window, "NEXT")
    end
    l_r_t, l_r_b, last_tracks = t, b, range_tracks
    return range_tracks
  else
    return last_tracks                                                          -- IF MOUSE RANGE IS SAME AS LAST RETURN SAVED TRACKS
  end
end
Is there any other approach to it?
This is the ONLY way to get both tracks and envelopes, I've tried other methods many times before but non did it as it should. It is also CPU hungry but I've managed that to only check when actual track changed

I give it Y range and it gives me all the tracks AND envelopes in that range

Your function avoids the problem with GetRelated and "NEXT" that I referred to above, since it finds trackview_window by checking "if top == arr_top", instead of assuming that trackview_window will always be the Xth (fourth, for example) child window returned by GetRelated.

Update on the window pinning issue - it was partly on my side. I mistyped the variable name I was passing in, so I was giving nil as the HWND argument to JS_Window_Find. Working fine now on Windows 8 and 10.

I would have expected that to cause an error from the extension though, but it returns a UserData pointer without complaining.

While looking into that thread: https://forum.cockos.com/showthread.php?t=221481
I wondered, if it would be any useful, if you could add CreateWindowExW and such to JS-extension-plugin as well.
This could allow us to add system-ui-elements into windows. Would be helpful for lokasenna as well, as he's currently refactoring his Gui-Lib. If he could add also system-ui-elements, it would be fantastic and help making guis look more like system-stuff.

I wondered, if it would be any useful, if you could add CreateWindowExW and such to JS-extension-plugin as well.
This could allow us to add system-ui-elements into windows. Would be helpful for lokasenna as well, as he's currently refactoring his Gui-Lib. If he could add also system-ui-elements, it would be fantastic and help making guis look more like system-stuff.

Interestingly - I was thinking along similar lines regarding adding create window api.

My thought's were to intercept multitouch messages in a transparent overlay window - store the data somewhere - in order to get multitouch into script GUI's.

However - so far - it's just thoughts going round my head and may not even be feasible...

Julian is there some function which returns screen resolution? I have some problems with track heights:

Code:
function GetTrackTBH(tbl)
  local total_h = 0
  local t, b, h, nt
  
  for i = #tbl , 1, -1 do                                            -- NEEDS TO BE REVERSED OR IT DRAWS WEIRD
    local track = tbl[i].track
    t, b, h = TBH[track].t, TBH[track].b, TBH[track].h
    total_h = total_h + h
    if t ~= 2344 then nt = t else total_h = total_h - h end          -- NEED TO FIX THIS,RESOLUTION DEPENDANT        -- FIX FOR WHEN THE TOP OF AS IS OUT PROJECT TOP IT WOULD EXPAND THE BOTTOM WHEN THE TOP TRACK IS OUT OF VIEW
  end
  
  if total_h == 0 then nt = 0 end
  
  return nt, total_h, b
end
Code:
if t ~= 2344 then nt = t else total_h = total_h - h end
If track is off the screen it returns in screen resolution, in my case I own QHD monitor so I need to set 2344 or it gets broken, if its 1080p then it needs to be around 1860-70 something in that range (need to check whats returned). Spotted this issue while was working on notebook

hm.... not sure how to calculate this

Code:
Resolution 2560 x 1440 

TOP OFFSET - 2344
Code:
Resolution 1920 X 1080

TOP OFFSET - 1984
Do not know what it takes into account when calculating this offset (track height when track is not in the view any more)?

Edit: nvm, added track visibility parameter to main tbl

Julian does JS_destroy_bitmap releases dc or I need to manually delete it?

second question:
Is it possible to get what is the current mouse cursor (want to track elements when cursor changes)?

and third, Julian take a look at PM

Question about JS_Window_Find

If I use JS_Window_Find to get the HWND from a window that doesn't exist, like:

Code:
reaper.JS_Window_Find ("Render to File", True)
If the Render to File window is closed and I run this script, then Reaper hang.

What does the rest of your code look like? It just returns nil for me on Linux and W10.

I am not aware of a function to release LICE bitmap dc's, so I think the dc is destroyed along with the bitmap.

This is an excellent idea for getting a more detailed cursor context. I quickly tested it, and it seems to work well. I will soon upload a new version with a Mouse_GetCursor function (and perhaps some window creation functions).

Julian I cannot reuse same bitmap do draw it again but on other place? I need to blit it to new bitmap?

If its the second part what would be the most simplest code to duplicate it?

Use case : Draw it multiple times on different coordinates

Default Q; How to refresh media explorer after scroll via API ?

Hi,


I'm tryong to scroll Media Explorer to a certain arbitrary pos,
the code works but the display isn't refreshed,
we can see the scrollbar scrolled a little to the bottom,
but the File List isn't refreshed, even when JS_Window_SetScrollPos return true.


Code:
local hWnd = reaper.JS_Window_Find("Media Explorer", true)
if hWnd == nil then return end  

local container = reaper.JS_Window_FindChildByID(hWnd, 0)
local file_LV = reaper.JS_Window_FindChildByID(container, 1000)
a = reaper.JS_Window_SetScrollPos( file_LV, "v", 80 )
reaper.JS_Window_Update( hWnd )
reaper.JS_Window_Update( container )
reaper.JS_Window_Update( file_LV )

I tried to push various Window Update without success.


What do I miss ?

Yes, you need to blit to a new bitmap: simply create a new bitmap of the same size, and LICE_Blit in "COPY" mode.

Code:
local SB_LINEUP = 0
local SB_LINEDOWN = 1
local SB_TOP = 6
local SB_BOTTOM = 7

-- go to top
reaper.JS_WindowMessage_Send(file_LV, "WM_VSCROLL", SB_TOP, 0,0,0)
-- scroll down to line #
for n = 1, 7 do
  reaper.JS_WindowMessage_Send(file_LV, "WM_VSCROLL", SB_LINEDOWN, 0,0,0)
end

Seems to works fine on Win7.

Code:
local hWnd = reaper.JS_Window_Find("Media Explorer", true)
if hWnd == nil then return end  
local container = reaper.JS_Window_FindChildByID(hWnd, 0)
local file_LV = reaper.JS_Window_FindChildByID(container, 1000)

local SB_LINEUP = 0
local SB_LINEDOWN = 1
local SB_TOP = 6
local SB_BOTTOM = 7

-- go to top
reaper.JS_WindowMessage_Send(file_LV, "WM_VSCROLL", SB_TOP, 0,0,0)
-- scroll down # of lines
for n = 1, 7 do
 reaper.JS_WindowMessage_Send(file_LV, "WM_VSCROLL", SB_LINEDOWN, 0,0,0)
end

Is there a regression in JS_Window_AttachTopmostPin? This used to work for me (though when I'm not entirely sure), but at least as of 0.988 with Reaper 5.978 this isn't working:

Code:
gfx.init('blargh!', 640, 480, 0, 100, 100)
local hwnd = reaper.JS_Window_Find('blargh!', true)
reaper.ShowConsoleMsg('found hwnd: ' .. tostring(hwnd) .. '\n')
reaper.JS_Window_AttachTopmostPin(hwnd)
function go()
    gfx.update()
    reaper.defer(go)
end
go()
The console does report a non-nil hwnd. But the pin isn't showing on the window. Anyone else see this?

Windows 10 x64 (build 1809).

Also, how might one fetch the hwnd of a docked gfx script that matches the hwnd returned by JS_Window_GetFocus() when the docked script is focused?

JS_Window_Find(title_passed_to_gfx_init, true) != JS_Window_GetFocus() when the docked script is focused. However this does work when the script is undocked and floating.

(I swear this used to work, in fact I even went out of my way to add a comment to that effect but either I was wrong at the time or the behavior changed, because it doesn't seem to work anymore.)
