I would like to use the check type entry in a form dialog but in a radio button fashion. ie only one check mark in that section at a time.
I’m trying to work it out and I think I know how to program it, I just don’t know where to implement it in the _FormDialogController
http://omz-software.com/pythonista/docs/ios/ui.html#switch
I hadn’t thought of switch, I think that looks better than check anyway :)
@ccc or @cvp , What is the method that is called within the form controller that would need to be overwritten/created?
Wow, and I've just found the segmented control too that @cvp was talking about. Am working to implement that. A single line of options is much better than a list. That's very nice, I'll let you know how I get on
@madivad try this and see field under age and value of returned diag when you select a segment

I don't understand the question if it is relative to the switch because your sample already contains a switch.
And without your own form_dialog....but it has been hard to find 😅

The last code is not correct if you scroll the dialog so the Segments are hidden and reshown back because the code adds a new subview each time. Let me some time to correct it.
That's the problem when you do this process in tableview_cell_for_row
Code corrected (and edited in the post), sorry for that
And if you want a dialog field as a button (radio, checkbox, ...), this code could help you.
You have to design the field with two images for your button, like:
sectionA_dicts.append(dict(type = 'text', title = 'My button',
key = 'button', button = ['iob:ios7_checkmark_32','iob:ios7_checkmark_outline_32']))
and the associated process:
def button_action(sender):
global c
sender.idx = 1 - sender.idx
sender.image = ui.Image.named(sender.images[sender.idx])
c.values[sender.name] = sender.idx
def my_tableview_cell_for_row(self,tv, section, row):
global c
c = self
cell = self.cells[section][row]
if len(cell.content_view.subviews) > 0:
tf = cell.content_view.subviews[0] # ui.TextField of value in row
item = self.sections[section][1][row]
if 'segments' in item:
# check if SegmentedControl already added
for sv in cell.content_view.subviews:
if type(sv) is ui.SegmentedControl:
return cell
segmented = ui.SegmentedControl()
segmented.name = cell.text_label.text
segmented.action = segmented_action
segmented.frame = tf.frame
segmented.x = c.view.width - segmented.width - 8
segmented.segments = item['segments']
cell.content_view.add_subview(segmented)
elif 'button' in item:
# check if Button already added
for sv in cell.content_view.subviews:
if type(sv) is ui.Button:
return cell
button = ui.Button()
button.name = cell.text_label.text
button.action = button_action
button.frame = tf.frame
button.width = button.height
button.x = c.view.width - button.width - 8
button.images = item['button']
button.title = ''
button.idx = 0
button.image = ui.Image.named(button.images[button.idx])
cell.content_view.add_subview(button)
elif type(tf) is ui.TextField:
tf.alignment=ui.ALIGN_RIGHT
return cell
and supporting color images in button:
.
.
.
sectionA_dicts.append(dict(type = 'text', title = 'My face',
key = 'face', button = ['emj:Smiling_1','emj:Disappointed']))
.
.
.
def button_action(sender):
global c
sender.idx = 1 - sender.idx
sender.image = ui.Image.named(sender.images[sender.idx]).with_rendering_mode(ui.RENDERING_MODE_ORIGINAL)
c.values[sender.name] = sender.idx
.

@cvp you are incredible...
I saw your first posts on the way to work and thought, “yeah, I have to get to that!” And now I log back and on and find this!!!! MUCH to digest!
I will be back (busy the next few days, but the kids are on holidays after tomorrow and I’ll slow down on the workload, so I should be able to get into this more)
Seriously, thanks for your contributions, you are awesome!
@cvp I finally got back to this, I got it all working as expected, the only issue I have is with the custom rows (My segmented control*, My button, and My face), they allow the cursor into the row label on the left hand side if the user touches near them.
I’ve spent a couple of hours going over the cradle and only minimally beginning to understand it :)
* the segmented control is ok in the custom/my_form_dialog and doesn’t allow the cursor in. It only allows the cursor when using the inbuilt dialog.
@madivad It is normal. When we create the new fields types in tableview_cell_for_row, the original TextField still exists. In the other case, the code deletes the TextField.
@madivad you can add these lines when you create a new field type
after
cell.content_view.add_subview(segmented)
Add
cell.content_view.remove_subview(tf)
del self.values[tf.name]
del tf
@cvp said:
cell.content_view.remove_subview(tf) del self.values[tf.name] del tf
I knew it was something like that, I was giving it a go but hadn’t got it right.
Thanks.
