How to select all items in a table view? (iOS python ui on Pythonista)

[BobPeltonUK]

I tried really everything but no success,also tried to look for it in here and google but Nothing !

Cycling all items and append them in the selected rows list has no effect!
Thanks in advance.

Here’s the def:

def SelezionaTutti(sender):
	chkbox=sender.superview['SwitchSelezionaTutti']
	listview=sender.superview['DatiDaExcel']
	if chkbox.value==True:
		for i in listview.data_source.items:
			listview.selected_rows.append(i)
	elif chkbox.value==False:
		listview.selectedindex=-1
	print(listview.selected_rows)```

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

Where do I put the tuple? It’s ok to iterate on datasource.items to select them?

[brumm]

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

I was having an issue setting TableView.selected_rows. I discovered that my problem was assignment doesn't replace the current list, but adds to it. So setting it to [] will not clear the current selections and adding say [(0, 1)] will simply add row 1 to the already selected rows.
The only way I could find to clear the current selections to [] was calling TableView.reload_data() before setting selected_rows.

Have you tried using append and clear or del, rather than setting to a new empty list?

I.e
tableview.selected_rows.append((0,1))

And either

tableview.selected_rows.clear()

Or
del tableview.selected_rows[:]

To clear it.

I can imagine a scenario where the selected_rows object is linked in some way to the native iOS list, and so just setting to a new object doesn't actually clear the old one..
