Date Picker w/ blank year

@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！
