Have you tried this?

Yes, there is a workaround. Select the video in the Files app and run the import file script. Don't know if there's a size limit, just tested it with a small one.

When you set .bordered to False you can change the settings (workaround)

        self['textfield1'].enabled = False
        self['textfield1'].bordered = False
        self['textfield1'].border_width = 0
        self['textfield1'].background_color = 'blue'
        self['textfield1'].text_color = 'white'

"TextField.action: A function or method that gets called when text field has finished editing."
So you could check if all textfields have a valid value, insert them to your db and clear the textfield.text

def textfield_action(self, textfield):
    # This is called after pressing RETURN
    if ...
        c.execute...
        self.tf_first.text = ''
        ...

Btw. this is an example of a own view class.

Don't know if it's still working... Workflow

Have you read all the comments in the getting started section? Here Or do you create a pyui project with a separate pyui file? Then you could write e.g. button_tapped in the Action field in the button preferences.

import ui

def button_tapped(sender):
    sender.title = 'Hello'

v = ui.load_view()
v.present('sheet')

length = len(self.view['tableview1'].data_source.items)
r = []
for i in range(1, length):
    t = tuple([0, i])
    r.append(t)
    self.view['tableview1'].selected_rows = r

TableView.selected_rows needs a sequence of selected rows, each as a 2-tuple (section, row). try (0, row)
