maya Python file writing progress bar ?

[Virbhadra Gupta]

here is my code

def exportAnimation():

    dataForJson = getAnimData(startFrame,endFrame)

    path = cmds. internalVar (utd=True)

    filePath = str (path)+'animaton.VGdata'

    exportData = json.dumps ( dataForJson , sort_keys= True , ensure_ascii=True , indent= 2 )

    File = open( filePath, 'w')

    load = File.write (exportData) 

    

    """

    Here i need to create file writing progressBar

    """

    #craete progressBar

    gMainProgressBar = maya.mel.eval('$tmp = $gMainProgressBar')

    

    # need to show progress of writing 

     

    

    File.close()

Do you only need progress for the act of writing the file? Is the write going to take a while and not the other steps? Any progress bar implementation is going to need you to feed it updated progress values to push it towards 100%. So if this file write really needs a progress bar then you have to split the writes up into chunks. Then you loop over the number of chunks, write the bytes and update the progress bar. 

Is this what you meant? Or did you want progress for the entire set of steps? Can you be more specific about what aspect has you stuck?

From your code the .write(exportData) is going to write all data at once. As Justin pointed out, you'll need to break up the write into smaller pieces so you can increment your progress bar. 

There are plenty of good examples in the world showing progress with python. This one should help:
