fxcore

Wrapper around the QtCore module for fxgui.

This module provides core functionality and custom classes to enhance the use of QtCore within the fxgui framework.

Classes:

Name	Description
FXSortFilterProxyModel	A filter model using fuzzy matching based on SequenceMatcher similarity ratios.

Examples:

Using FXSortFilterProxyModel with a search bar:

>>> from fxgui.fxcore import FXSortFilterProxyModel
>>> proxy = FXSortFilterProxyModel(ratio=0.6)
>>> proxy.setSourceModel(my_model)
>>> search_bar.textChanged.connect(proxy.set_filter_text)

Classes

FXSortFilterProxyModel

FXSortFilterProxyModel(
    ratio: float = 0.5,
    color_match: bool = True,
    parent: Optional[QWidget] = None,
)

Bases: QSortFilterProxyModel

A filter model that uses SequenceMatcher to filter items based on a similarity ratio. The similarity ratio is a value between 0 and 1, where 1 indicates a perfect match.

Examples:

Filter a list of items using the FXSortFilterProxyModel

>>> items = ["apple", "banana", "cherry", "date"]
>>> search_bar = QLineEdit()
>>> view = QListView()
>>> model = QStringListModel()
>>> model.setStringList(items)
>>> proxy = FXSortFilterProxyModel()
>>> proxy.setSourceModel(model)
>>> view.setModel(proxy)
>>> search_bar.textChanged.connect(proxy.set_filter_text)

Notes

Base code from Alex Telford: LinkedIn post

Initialize the FXSortFilterProxyModel.

Parameters:

Name	Type	Description	Default
ratio	float	The ratio threshold for filtering.	0.5

parent	Optional[QWidget]	The parent widget.	None

Methods:

Name	Description
data	Get the data for a given role and index.
filterAcceptsRow	Determine whether a row should be accepted by the filter.
lessThan	Compare two indices to determine their order.
set_color_match	Set whether to enable color matching.
set_filter_text	Set the filter text.
set_ratio	Set the ratio threshold for filtering.
set_show_all	Set whether to show all items regardless of the filter.

Functions
