Date Picker w/ blank year

cvp

@osamu try this little script. You will not see the wanted "----" but after the now-date, day/month/years are grayed and not selectable with automatic return to today picker. I'm sure I'm not clear, thus try it.

import ui
v = ui.View()
v.name = 'for @osamu'
v.frame = (0,0,300,150)
d = ui.DatePicker()
d.frame = v.frame
d.mode = ui.DATE_PICKER_MODE_DATE
v.add_subview(d)
objc = ObjCInstance(d)
nsDate = ObjCClass('NSDate').alloc().init() # initialized with now-date
#print(dir(nsDate))
objc.setMaximumDate_(nsDate)
v.present('sheet')

@cvp said:

objc.setMaximumDate_(nsDate)

Thank you, I’m interested in the above attribute.

osamu

@cvp I tried the first version but Pythonista claimed create_objc_class() is missing. There may be some more. I guess I need to sneak into your library and steal them.

@osamu my error

from   objc_util import *

osamu

@cvp I got it. Thank you.

@cvp This script initializes the year as 2019. If I set;
years = [str(y) for y in range(1605,datetime.now().year+1)] + ['----']
the initial year is set to 1605 and we’re far away from —— and recent years. Can we control this initial value?

Have you tried reversing the list?

osamu

@JonB That’s a good idea 👍

@cvp one last question.
Can I set the initial year?
The following does not work.

class MyUIPickerView(ui.View):
    def __init__(self, data, horiz=False,myRowHeight=100, myDidSelectRow=None, **kwargs):
        super().__init__(**kwargs)
        
        UIPickerView = ObjCClass('UIPickerView')
        self._picker_view = UIPickerView.alloc().initWithFrame_(ObjCInstance(self).bounds()).autorelease()
        ObjCInstance(self).addSubview_(self._picker_view)
       ...
       self._picker_view.selectedRow = XXX

Thanks in advance.

@osamu selectedRow is not an attribute of UIPickerView but is an user attribute set in the pickerView_didSelectRow_inComponent_ delegate, thus you can't set it.

I think we would need to use kind of

.
.
.
        self._picker_view.horiz = horiz
        xxx = 1
        self._picker_view.selectRow_inComponent_animated_(xxx,0,True)

Tested, ok

@cvp Yes, it works. Thanks！
