prett6 1.0.3

A Pretty Project Framework

A pretty project framework for Python3 & PySide6.

I hope it is useful for you, too. :D

Dict Storage

All the project items’ values are stored in the project.value dict. The key is the item name. Generally this dict can be serialized and stored in the file if the dict can be pickled directly.

import prett


class ItemDemo(prett.IntProjectItem):
    pass

class ProjectDemo(prett.AbstractProject):
    def __init__(self):
        self.width = ItemDemo(self)
        self.height = ItemDemo(self)

p = ProjectDemo()
p.width.int.value = 16
p.height.int.value = 20
print(p.value)  # {'width': '16', 'height': '20'}

Type Conversion

In prett, there are default type conversion in string-int and string-float. When the item is inherited from StringIntItem, the item value is stored in string type, and its int property will automatically convert to or from string type.

import prett


class ItemDemo(prett.IntProjectItem):
    pass

class ProjectDemo(prett.AbstractProject):
    def __init__(self):
        self.length = ItemDemo(self)

p = ProjectDemo()
p.length.string.value = '200'
print(p.length.int.value)  # 200, type is int

Changed Signal

When the value of property change, the changed signals of project, item, and properties will be emitted.

import prett


class ItemDemo(prett.IntProjectItem):
    pass

class ProjectDemo(prett.AbstractProject):
    def __init__(self):
        self.width = ItemDemo(self)
        self.height = ItemDemo(self)

p = ProjectDemo()
p.width.int.value = 16  # p.changed signal emitted, p.width.changed emitted
                        # then p.width.string.changed emitted, p.width.int.changed emitted
