Examples for dialogs.form_dialog() ?
-
Look at this discussion
https://forum.omz-software.com/topic/4260/dialogs-form_dialog-wrapper-helper -
import dialogs sections = [] fields = [] field = {'type':'switch','key':'chrc1','title':'yas','tint_color':'linen'} fields.append(field) sections.append(('title section 1', fields)) fields = [] field = {'type':'switch','key':'chrc2','title':'ying','tint_color':'linen'} fields.append(field) sections.append(('title section 2', fields)) dialogs.form_dialog(title='fu',sections=sections) -
You could have footer also in the sections
import dialogs import datetime form_list_of_sections = [] sectionA_dicts = [] sectionA_dicts.append(dict(type = 'text', title = 'First Name', key = 'first', placeholder = 'John')) sectionA_dicts.append(dict(type = 'text', title = 'Last Name', key = 'last', placeholder = 'Doe')) sectionA_dicts.append(dict(type = 'number', title = 'age', key = 'age', placeholder='30')) form_list_of_sections.append(('Section A', sectionA_dicts, 'Section A ends')) sectionB_dicts = [] sectionB_dicts.append(dict(type = 'date', title = 'Date Of Birth', key = 'DOB', value = datetime.date.today())) sectionB_dicts.append(dict(type = 'url', title = 'Home Page', key = 'homepage', placeholder = 'http://example.com')) form_list_of_sections.append(('Section B', sectionB_dicts, 'Section B ends')) sectionC_dicts = [] sectionC_dicts.append(dict(type = 'email', title = 'email', key = 'email', placeholder = 'name@mailserver.com')) sectionC_dicts.append(dict(type = 'switch', title = 'is_married', key = 'is_married', value = True)) sectionC_dicts.append(dict(type = 'check', title = 'is_registered', key = 'is_registered', value = False)) form_list_of_sections.append(('Section C', sectionC_dicts, 'Section C ends')) diag = dialogs.form_dialog(title = 'Form Dialog', sections=form_list_of_sections) print(diag) -
Not sure what’s happening here, if it is intended or something is broken in iOS, but a lot of fields appear to have their alignment broken. This is on the iPad with iPad os. Is there a way to force right alignment?
-
@madivad True, I also remarked this problem but with the beta version of Pythonista3
Édit: temporarily, I've added some blanks at end of each field title
-
@cvp Do you mean it’s only a problem with the beta? I am on the beta.
-
-
@cvp do you think there would be a workaround using the objc tools?
-
@madivad I think that Objectivec is not needed and that you could use tableview_cell_for_row delegate
Édit: but you need to have your own form_dialog, I think 😢
-
@cvp ok, thx
-
@madivad try this, waiting that @omz correct it

@madivad better with
if len(cell.content_view.subviews) > 0: tf = cell.content_view.subviews[0] # ui.TextField of value in row if type(tf) is ui.TextField: tf.x += 20 tf.width -= 20 -
@cvp said:
if type(tf) is ui.TextField:
PEP8: Avoid directly comparing types. Use isinstance(tf, ui.TextField) instead.
-
@ccc ok, PEP are conventions. Why "Avoid directly comparing types"? Is there a technical reason? You have to agree that "type(tf) is xxx" is more readable than the PEP code 😀
-
@ccc found that, and I like it, thus, forget my previous post 😀
isinstance caters for inheritance (an instance of a derived class is an instance of a base class, too), while checking for equality of type does not (it demands identity of types and rejects instances of subtypes, AKA subclasses).
Normally, in Python, you want your code to support inheritance, of course (since inheritance is so handy, it would be bad to stop code using yours from using it!), so isinstance is less bad than checking identity of types because it seamlessly supports inheritance.
It's not that isinstance is good, mind you—it's just less bad than checking equality of types
-
@cvp but but but...
It's a text field, why not just align it right?I did just that and it's perfect now:
tf.alignment=ui.ALIGN_RIGHT:)
Is there a way to do that without creating our own custom dialogue type?
-
@madivad said:

I don't think so because dialogs.form_dialog does the "present" and you can't modify something after the view presentation. But perhaps somebody else could find another way.
-
@madivad said:
tf.alignment=ui.ALIGN_RIGHT
Good idea but sometimes, user may prefer a left alignment for text and a right alignment for numbers, thus, up to you 😀
-
@cvp maybe, but in any case, left aligned to the fields title is ugly to me. I can't think of a usecase where you would want it like that. Maybe in an RTL language, but I wouldn't know.
About the modifying after the present, yes makes sense. Having the custom dialogue type is no big issue. I'll use that.
Thanks for your help!
-
For info, in all my big scripts I always use my own form_dialog, while keeping the standard dialogs._FormDialogController, because in my dialog views I add some buttons or I add some types like SegmentedControl or ImageView or even MkMapView, so...
