How to use Allow Drop File on form components?.
i.e: Drag and drop text file to CEMemo or an Image to CEImage?
Any example?

in the form's OnDropFiles event fetch the current mouse cursor position

then use screenToClient(x,y) on the controls to figure out which control the mouse is over

Thanks DB, the script below is an example to drag components on the form:

Code:
memo = UDF1.CEMemo1
image = UDF1.CEImage1

local down = false

function ObjMouseDown(sender, x, y)
 down = true
end

function ObjMouseMove(sender, x, y)
 if down == true then
 local x,y = getMousePos()
 x1,y1 = UDF1.ScreenToClient(x,y)
 sender.Top = y1
 sender.Left = x1
 end
end

function ObjMouseUp(sender, x, y)
 down = false
end


UDF1.show()
memo.onMouseDown = ObjMouseDown
memo.onMouseMove = ObjMouseMove
memo.onMouseUp = ObjMouseUp

image.onMouseDown = ObjMouseDown
image.onMouseMove = ObjMouseMove
image.onMouseUp = ObjMouseUp


But, I am sorry for not clear information. What I mean is to drag and drop file from explorer to the controls.
i.e : drag a text file from explorer to CEMemo and the text automatically as CEMemo Text, or an image to CEImage, etc.

Similar like do in Lazarus (with listbox control), example:

Code:
procedure TForm1.FormDropFiles(Sender: TObject; const FileNames: array of String);
var
  i: Integer;
begin
  for i := Low(FileNames) to High(FileNames) do
    ListBox1.Items.Add(FileNames[i]);
end;
end;


I try port to CE Lua:

Code:
form.AllowdropFiles = true

function form_FormDropFiles(sender, FileNames)
 FileNames = {}
 for i = 0, #FileNames do
      ListBox1.Items.Add(FileNames[i]);
 end
end


Of course doesn't work. So, is there any ways to do it properly in CE Lua?.

of course that won't work as you're throwing away the filenames tables before you read through it

and do you assign that function to OnDropFiles ?

Code:
if f then f.destroy() end
f=createForm()
f.FormStyle='fsSystemStayOnTop'
f.AllowDropFiles=true

m=createMemo(f)
m.setSize(200,150)
m.setPosition(5,5)
m.Lines.Add('This is Memo')
m.Lines.Add('Please drag in the TXT file')

img=createImage(f)
img.Stretch=true
img.Align='alClient'
function setPrompt(str,v)
  img.Canvas.clear()
  img.Canvas.gradientFill(0,0,img.width,img.height,0x55,0xff00ff,v)
  img.Canvas.Brush.Style=1
  img.Canvas.textOut(0,200,str)
end
setPrompt('This is image , Please drag in the jpg file',1)

f.OnDropFiles=function(sender,filename)
  for k,v in pairs(filename) do
    local fi=('.txt' or '.ini' or '.lua')
    local path,name = string.match(string.lower(v),'(.*\\)(.*)')
    local txt=string.match(string.lower(v),'(.*)%.txt')
    local jpg=string.match(string.lower(v),'(.*)%.jpg')
    if jpg then
      img.Picture.loadFromFile(jpg..'.jpg')
      setPrompt('Current file：'..path..name,0)
    elseif txt then
      local file=io.open(utf8ToAnsi(txt)..'.txt','r')
       if file then m.Lines.Add(file:read('*a'))  file:close() end
      setPrompt('Current file：'..path..name,0)
    else
      beep()  setPrompt('The file is not in jpg or txt format',0)
    end
  end
end

Thanks DB and lua... my bad, not really understand what I am trying to do by follow some articles for lazarus/delphi style to drag and drop process.

It's work and this is script according to my needs.

Code:
if f then f.Destroy() end

f = createForm()
f.setSize(600, 400)
f.Position = 'poScreenCenter'
f.Caption = 'Test Drag And Drop'
f.AllowdropFiles = true

memo1 = createMemo(f)
memo1.setSize(580,340)
memo1.setPosition(10,10)
memo1.ScrollBars = 'ssAutoBoth'

btn1 = createButton(f)
btn1.setSize(150, 30)
btn1.setPosition(225, 360)
btn1.Caption = 'Clear Memo Text'

f.OnDropFiles=function(sender,filename)
 for k,v in pairs(filename) do
 local txt = string.match(string.lower(v),'(.*)%.txt')
 if txt then
    local file=io.open(txt..'.txt','r')
    if file then
       local content = file:read('*a')
       file:close()
       memo1.Clear()
       memo1.Lines.Text = content
    else
       showMessage('file error')
    end
  end
 end
end

btn1.OnClick = function(sender)
 memo1.Clear()
end

You'd better write it safely, because if you have a file name with wide characters, it may appear that the file does not exist
Code:
local file=io.open(utf8ToAnsi(txt)..'.txt','r')

Yes, I know. The script I made has no error handle checking. Actually I am use functions IsDirExist() or IsFileExist including check if the file name contains native characters or not, and use assertion too.
Thank to remind me
