orb.dialogs.app_store.app_summary.app_summary module

class orb.dialogs.app_store.app_summary.app_summary.AppSummary(app, *args, **kwargs)

Bases: BoxLayout

The AppSummary is the card that shows in both the installed and available apps.

app

ObjectProperty(defaultvalue=None, rebind=False, **kw) Property that represents a Python object.

Parameters:
defaultvalue: object type

Specifies the default value of the property.

rebind: bool, defaults to False

Whether kv rules using this object as an intermediate attribute in a kv rule, will update the bound property when this object changes.

That is the standard behavior is that if there’s a kv rule text: self.a.b.c.d, where a, b, and c are properties with rebind False and d is a StringProperty. Then when the rule is applied, text becomes bound only to d. If a, b, or c change, text still remains bound to d. Furthermore, if any of them were None when the rule was initially evaluated, e.g. b was None; then text is bound to b and will not become bound to d even when b is changed to not be None.

By setting rebind to True, however, the rule will be re-evaluated and all the properties rebound when that intermediate property changes. E.g. in the example above, whenever b changes or becomes not None if it was None before, text is evaluated again and becomes rebound to d. The overall result is that text is now bound to all the properties among a, b, or c that have rebind set to True.

**kwargs: a list of keyword arguments
baseclass

If kwargs includes a baseclass argument, this value will be used for validation: isinstance(value, kwargs[‘baseclass’]).

Warning

To mark the property as changed, you must reassign a new python object.

Changed in version 1.9.0: rebind has been introduced.

Changed in version 1.7.0: baseclass parameter added.

on_touch_down(touch)

Receive a touch down event.

Parameters:
touch: MotionEvent class

Touch received. The touch is in parent coordinates. See relativelayout for a discussion on coordinate systems.

Returns:

bool If True, the dispatching of the touch event will stop. If False, the event will continue to be dispatched to the rest of the widget tree.

selected

NumericProperty(defaultvalue=0, **kw) Property that represents a numeric value.

It only accepts the int or float numeric data type or a string that can be converted to a number as shown below. For other numeric types use ObjectProperty or use errorhandler to convert it to an int/float.

It does not support numpy numbers so they must be manually converted to int/float. E.g. widget.num = np.arange(4)[0] will raise an exception. Numpy arrays are not supported at all, even by ObjectProperty because their comparision does not return a bool. But if you must use a Kivy property, use a ObjectProperty with comparator set to np.array_equal. E.g.:

>>> class A(EventDispatcher):
...     data = ObjectProperty(comparator=np.array_equal)
>>> a = A()
>>> a.bind(data=print)
>>> a.data = np.arange(2)
<__main__.A object at 0x000001C839B50208> [0 1]
>>> a.data = np.arange(3)
<__main__.A object at 0x000001C839B50208> [0 1 2]
Parameters:
defaultvalue: int or float, defaults to 0

Specifies the default value of the property.

>>> wid = Widget()
>>> wid.x = 42
>>> print(wid.x)
42
>>> wid.x = "plop"

 ValueError: NumericProperty accept only int/float

Changed in version 1.4.1: NumericProperty can now accept custom text and tuple value to indicate a type, like “in”, “pt”, “px”, “cm”, “mm”, in the format: ‘10pt’ or (10, ‘pt’).
