Callback function triggered when a file is dragged and dropped onto the window.

Function

Synopsis

love.filedropped( file )

Arguments

DroppedFile file
The unopened File object representing the file that was dropped.

Returns

Nothing.

Examples

Read and print the file, drag-and-dropped to love window using (File):read and (File):getFilename.

function love.filedropped(file)
	file:open("r")
	local data = file:read()
	print("Content of " .. file:getFilename() .. ' is')
	print(data)
	print("End of file")
end

If dropped file is a .png, use it to create a löve image using love.image and love.graphics

function love.filedropped(file)	
	filename = file:getFilename()
	ext = filename:match("%.%w+$")

	if ext == ".png" then
		file:open("r")
		fileData = file:read("data")
		img = love.image.newImageData(fileData)
		img = love.graphics.newImage(img)
	end
end

Notes

File:open must be called on the file before reading from or writing to it. File:getFilename will return the full platform-dependent path to the file.
