pygame file dialog

[KLL]

i am stuck with PYTHON PYGAME
and need a popup window / or MENU to allow a user to select a ( existing) file from the filesystem.

anybody has a ready code?

[ghans]

I guess using TkInter instead is the easeist option ... not very beautiful , though .

You should have a look at PGU (Phils pyGame Utilities)

http://www.pygame.org/project-PGU+-+Phi ... 8-471.html

It has a range of GUI elements including a file open dialog.

[KLL]

thanks, i will check on both,
but i had already bad luck with mixing PYGAME and Tkinter
as a Tkinter dialog is it exactly the same as with the Python 2 IDE File open
see attachment, nice.
but i started with the gtk ( mixed / called from PYGAME )
and i am not able to close the dialog, but it actually works to choose a file.
possibly only one "smart" line of code missing.
that one looks like the new filemanager PCManFM
see attachment (low quality!)

there must be a way that it is not needed to mix the various GUIs.

ok, here is a "BAD ASS" trick: the PYTHON gurus will hate me for that
the python gtk file open dialog is a stand alone program
and saves the result to a RAM DISK file.

Code: Select all

#/pytho_audio/file_open/fileopenwindow.py
# from github majorsilence pygtknotebook

# KLL 16.01.2015
# start terminal or suprocess : python fileopenwindow.py
# result:
# there is a file in /run/shm/filechoose.txt
# it contains:
# if window open: "!open"
# if window closed "!close"
# if button [Cancel] "!cancel"
# if button [Open] or double click on file "/path/filename"


import pygtk
pygtk.require('2.0')
import gtk
import sys
import os

def save_to_file(fileline="") :
    if os.name == 'posix':      # RPI linux
        RAMDISKpath = '/run/shm/'
    else :
        RAMDISKpath = 'C:/tmp/'
        
    sfiledata   = RAMDISKpath+"filechoose.txt"
        
    fdat = open(sfiledata,"w")
    fdat.write(fileline+"\n")
    fdat.close()

def main():

    #file filters used with the filechoosers
    text_filter=gtk.FileFilter()
    text_filter.set_name("Text files")
    text_filter.add_mime_type("text/*")
    all_filter=gtk.FileFilter()
    all_filter.set_name("All files")
    all_filter.add_pattern("*")
    filename=None
    
    save_to_file("!open")     # open the file in ramdisk for masterprogram to check   
    dialog=gtk.FileChooserDialog(title="Select a File", parent=None, action=gtk.FILE_CHOOSER_ACTION_OPEN, buttons=(gtk.STOCK_CANCEL, gtk.RESPONSE_CANCEL, gtk.STOCK_OPEN, gtk.RESPONSE_OK))
    #dialog.connect("delete-event",gtk.main_quit)
    if (text_filter != None) and (all_filter != None):
        dialog.add_filter(text_filter)
        dialog.add_filter(all_filter)

    filename = "!close"    
    response = dialog.run()
    if response == gtk.RESPONSE_OK:
        filename = dialog.get_filename()
        #print "File Choosen: ", filename
    elif response == gtk.RESPONSE_CANCEL:
        filename = "!cancel"
        #print 'Cancel Clicked'
    save_to_file(filename)        
    dialog.destroy()
    sys.exit(filename)  # prints the "filename" OR "!cancel" after all that stupid gtk warnings in terminal window
                        # but if you click window[x] get nothing!

any main program can call that program and evaluate the result by reading the file
