Load and read a file from selection in filechooser

[NDD Mais]

Hi

I'm trying to read an mp4 file with videoplayer, from selection, since the user, when he clicks on the open button, a boxdialog appears, giving the option to choose to read or something else, and after accepting to read, the player had to be able to read it. However, even satisfying the condition, which generates an error, does not work anyway. Can you help me

Here is an example of a simple filechooser.  The point of this exercise was to add a drive selector.  This is a relatively simple example that does a load and save dialogs with the filechooser.

https://github.com/ElliotGarbus/KivyFileAndDrive

 

run main.py 

You can ignore main1.py,  it is a simple test of the popup using Factory.

 

 

The filter is set to only show *.txt or *.pdf files.

Hi

Thanks for the answer. However, I think I didn't expose the subject well, from what I understood in your answer. The file loading and reading happened satisfactorily, due to a problem, it started when I put a Boxdialog with options 'Open' and 'others'...for other purposes to be considered. Between the open button and reading the selected file, the problem here is that it doesn't load the file to read in the reading function (o_dx), the variable in that function doesn't even receive the path. 

Regards

Ok, your proposal solution, a little different from what i wanted, but give it a try, and see how it looks when inserted into the main program and its layouts

[elli...@cox.net]

Looking at this code:

 

class Screen2(Screen):

    theme_cls = ThemeManager()

 

    def selected(self, filechooser,filename):

        p=self.selected(filename)

        return p

 

You have a problem that selected is calling itself.  No need for recursion here. 

Also note that selection, filename here, is a list.  Print it out, you will see it a list at that the filename is an absolute filename with full path info.

You might want to change your kv code to:

 

on_selection: root.selected(filechooser.selection[0])

[elli...@cox.net]

I was not suggesting you use the code – or change the look.  It is just an example of a file chooser.

The problem here is that the select function gets the file path, but does not transmit it to the read function to be able to read it.

You are calling selected when the file is selected.  Store the selected filename in an instance variable, let’s call that self.selected_file.  In your read method() use self.selected_file to read the file.

Alternatively, you could call read() and pass in the filename from kv.  The core of the problem is calling selected() from read(),
