示例1: fedit
# 需要導入模塊: from matplotlib.backends.qt_compat import QtWidgets [as 別名]
# 或者: from matplotlib.backends.qt_compat.QtWidgets import QApplication [as 別名]
def fedit(data, title="", comment="", icon=None, parent=None, apply=None):
"""
Create form dialog and return result
(if Cancel button is pressed, return None)
data: datalist, datagroup
title: string
comment: string
icon: QIcon instance
parent: parent QWidget
apply: apply callback (function)
datalist: list/tuple of (field_name, field_value)
datagroup: list/tuple of (datalist *or* datagroup, title, comment)
-> one field for each member of a datalist
-> one tab for each member of a top-level datagroup
-> one page (of a multipage widget, each page can be selected with a combo
box) for each member of a datagroup inside a datagroup
Supported types for field_value:
- int, float, str, unicode, bool
- colors: in Qt-compatible text form, i.e. in hex format or name (red,...)
(automatically detected from a string)
- list/tuple:
* the first element will be the selected index (or value)
* the other elements can be couples (key, value) or only values
