tableview_did_select

[mikael]

@Appletrain, please use the friendly code button </> to surround code with backticks and make it much more readable.

So the dialog comes up, you make the selection normally, but the return value is None?

Very curious: if you put the dialog call in another function that you call from did_select with ui.delay (very small delay), it works.

@Appletrain put @ui.in_background just before the def

@ui.in_background	
def tableview_did_select(self, tableview, section, row):

@cvp, cool!

But then I do not really understand why ui.delay and the button action handler worked, as they are both run on the main UI thread, as is tableview_did_select.

@mikael I don't understand too but I often (not always) meet this problem.
The problem comes from the wait_modal in the dialog, it doesn't wait sometimes

@cvp @mikael this question is me trying to understnd.

is it posible the dialoge is making a synchronus call? or possible the dialoge delegate method is retuning before the diloge skipping dialoge return all together?

[cvp]

@stephen I think it is something like that..

@mikael @cvp @Appletrain sorry about post miss-hap.. i found this to work. but it bypasses dialogs module..

import ui

class DataSource(object):
	def __init__(self, items):
		self.items=items
		
	def tableview_cell_for_row(self, tableview, section, row):
		# Create and return a cell for the given section/row
		cell = ui.TableViewCell()
		cell.text_label.text =  self.items[row]
		return cell
	
	def tableview_number_of_sections(self, tableview):
		# Return the number of sections (defaults to 1)
		return 1

	def tableview_number_of_rows(self, tableview, section):
		# Return the number of rows in the section
		return len(self.items)

class TV:
	def __init__(self):
		self.menu_one_options = ['Banana', 'Orenge', 'Grape']
		self.menu_two_options = ['happy', 'days', 'are', 'here', 'again']
		frame=(0, 0, 200, 600)
		
		self.selected=''
		
		self.tv1 = ui.TableView(frame=frame)
		self.tv1.name='menu-one'
		self.tv1.delegate = self
		self.tv1.hidden=False
		self.tv1.data_source = DataSource(self.menu_one_options)
		self.tv1.present('sheets')
		
		self.tv2 = ui.TableView(frame=frame)
		self.tv2.name='menu-two'
		self.tv2.delegate = self
		self.tv2.hidden=True
		self.tv2.data_source = DataSource(self.menu_two_options)
		
		
	def tableview_did_select(self, tableview, section, row):
		if not self.tv1.hidden:
			self.selected += tableview.data_source.items[row] + ' '
			self.tv1.hidden=True
			self.tv2.present('sheets')
			self.tv2.hidden=False
		elif not self.tv2.hidden:
			self.selected += tableview.data_source.items[row]
			print (self.selected)
			self.tv2.hidden=True
			self.tv1.close()
			self.tv2.close()
