Thanks everyone,
@JonB You cleared my doubt on @ui.in_background, Now I'm using threading instead of ui.in_background

import ui,threading as thr

class view():
    def __init__(self):
        self.flag = True
        content = ui.TableViewCell()
        play = ui.Button(frame = (259,0,50,content.height))
        pause = ui.Button(frame = play.frame)
        
        play.image = ui.Image('iob:ios7_play_256')
        pause.image = ui.Image('iob:pause_256')
        pause.hidden = True
        play.action = self.Play
        pause.action = self.Pause
        label = ui.Label(frame =(0,0,0,content.height))
        label.touch_enabled = False
        
        label.background_color = 'blue'
        

        self.play = play
        self.pause = pause
        self.label = label
        self.flag = False
        content.content_view.add_subview(play)
        content.content_view.add_subview(pause)
        content.content_view.add_subview(label)
        self.content = content
    def table(self):
        return self.content
        
    def Play(self,sender):
        t = thr.Thread(target=self.Playy,args=(sender,))
        t.daemon = True
        t.start()
    def Pause(self,sender):
        t = thr.Thread(target=self.Pausee,args=(sender,))
        t.daemon = True
        t.start()
    def Playy(self,sender):
        sender.hidden = True
        self.pause.hidden = False
        import time
        for a in range(320):
            self.label.width = a
            time.sleep(0.1)
            if self.flag:
                self.flag = False
                return 
    

    def Pausee(self,sender):
        sender.hidden = True
        self.play.hidden = False
        self.flag = True
        
class Llist():
    def tableview_number_of_rows(self,t,s):
        return 40
    def tableview_cell_for_row(self,t,s,r):
        return view().table()
        
a=ui.TableView()
a.data_source = Llist()
a.allows_selection = False
a.present()

The pause button is not working

import ui

class view():
    def __init__(self):
        self.flag = True
        content = ui.TableViewCell()
        play = ui.Button(frame = (259,0,50,content.height))
        pause = ui.Button(frame = play.frame)
        
        play.image = ui.Image('iob:ios7_play_256')
        pause.image = ui.Image('iob:pause_256')
        pause.hidden = True
        play.action = self.Play
        pause.action = self.Pause
        label = ui.Label(frame =(0,0,0,content.height))
        label.touch_enabled = False
        
        label.background_color = 'blue'
        

        self.play = play
        self.pause = pause
        self.label = label
        self.flag = False
        content.content_view.add_subview(play)
        content.content_view.add_subview(pause)
        content.content_view.add_subview(label)
        self.content = content
    def table(self):
        return self.content
    
    @ui.in_background
    def Play(self,sender):
        sender.hidden = True
        self.pause.hidden = False
        import time
        for a in range(320):
            self.label.width = a
            time.sleep(0.1)
            if self.flag:
                self.flag = False
                return 
    
    @ui.in_background
    def Pause(self,sender):
        sender.hidden = True
        self.play.hidden = False
        self.flag = True
        
class Llist():
    def tableview_number_of_rows(self,t,s):
        return 40
    def tableview_cell_for_row(self,t,s,r):
        return view().table()
        
a=ui.TableView()
a.data_source = Llist()
a.allows_selection = False
a.present()

I am trying to make a downloader's ui,
but the problem after it pauses, the progress get resetted when scrolled down and scrolled up.

import ui

@ui.in_background
def progress_(sender):
    a=sender.superview
    for f in range(150):
        
        a['progress'].width=f
    return a['progress']

def make():
    a=ui.TableViewCell()
    b=ui.Label(frame=a.content_view.frame)
    c=ui.Label(frame=a.content_view.frame)

    c.name='progress'
    c.width=0
    c.bg_color='lightblue'
    h=ui.Button(frame=b.frame)
    h.x=250
    h.width=59
    h.action=progress_
    h.image=ui.Image('iob:arrow_expand_256')
    
    a.add_subview(b)
    a.add_subview(h)
    a.add_subview(c)
    return a
class listdata():
    def __init__(self):
        self.tv=ui.TableViewCell()
        self.b=ui.Button()
        self.l=ui.Label()
    def tableview_number_of_rows(self,t,s):
        return 20
    def tableview_cell_for_row(self,t,s,r):
        return make()
    

s=ui.TableView()
s.allows_selection=False

s.data_source=listdata()
s.present()

On the section header how to change its background color
But this doesn't work for me

def tableview_title_for_header(self, tableview, section):
    # Return a title for the given section.
    # If this is not implemented, no section headers will be shown.
    self.background_color='black'
    return 'Some Section'

@JonB Actually I am creating a Downloader like IDM So I am creating this view with a pause and resume button and the label as the progress bar how can I Do this with tableviewcell, An example would be helpful.
Thanks in advance.

I am trying to create a table without using tableview because tableview doesn't cant help me, so I created a scrollview with a view inside that view is the row, but I am having trouble with view I can't create more than one row.

view.py

import ui
d=ui.load_view()
def g(text,no):
    
    sv=d['scrollview1']
    v=sv['view1']
    l=v['label1']
    b=v['button1']
    
    l.text=l.background_color=b.background_color=text
    
    v.add_subview(l)
    v.add_subview(b)
    v.frame.y=no*(l.frame.height+5)
    sv.add_subview(v)
    
for ss,s in enumerate(['red','green'],1):
    g(s,ss)
    
d.present()

dialogs.form_dialog(title='fu',fields=[{'type':'switch','key':'chrc','title':'yas','tint_color':'linen'}])

How do I use sections?

Can anyone give me examples on dialogs.form() ?

Thanks in Advance

Thanks ,I used Auto-Lock in settings to 30-Seconds and used

console.set_idle_timer_disabled(True)

Untill the timer runs out and changed the flag to False.

I am creating a timer after the timer runs out I want to lock the screen .How do I do that?
