Qcompleter的匹配机制问题[Bug]:

[iMallpa]

What happened?

Qcompleter的匹配机制看起来是输入的文本和列表stands中的对比，只有在输入的内容和列表内字符串的文本从左到右匹配才会展示。我觉得这样的匹配机制不妥，我建议只要输入的文本存在于字符串的文本，就展示条目。

Operation System

Windows 10 22H2

Python Version

3.12 64bit

PyQt/PySide Version

PyQt/PySide-Fluent-Widgets Version

may newest

How to Reproduce?

Minimum code

# coding:utf-8
import sys
from PyQt5.QtCore import Qt, QStringListModel
from PyQt5.QtWidgets import QApplication, QWidget, QHBoxLayout, QCompleter

from qfluentwidgets import LineEdit, SearchLineEdit

class CustomCompleter(QCompleter):
    """ Custom QCompleter to show all suggestions regardless of input text """

    def __init__(self, parent=None):
        super().__init__(parent)
        self.setCaseSensitivity(Qt.CaseInsensitive)
        self.setMaxVisibleItems(10)

    def splitPath(self, path):
        # Override this method to always show all completions
        return self.model().stringList()

class Demo(QWidget):

    def __init__(self):
        super().__init__()
        # self.setStyleSheet("Demo {background: rgb(32, 32, 32)}")
        # setTheme(Theme.DARK)

        self.hBoxLayout = QHBoxLayout(self)
        self.lineEdit = SearchLineEdit(self)

        # add completer
        stands = [

        ]
        self.model = QStringListModel(stands)

        self.completer = CustomCompleter(self.lineEdit)
        self.completer.setModel(self.model)
        self.lineEdit.setCompleter(self.completer)

        self.resize(400, 400)
        self.hBoxLayout.setAlignment(Qt.AlignCenter)
        self.hBoxLayout.addWidget(self.lineEdit, 0, Qt.AlignCenter)

        self.lineEdit.setFixedSize(400, 33)
        self.lineEdit.setClearButtonEnabled(True)
        self.lineEdit.setPlaceholderText('搜索地点')

if __name__ == '__main__':
    # enable dpi scale
    QApplication.setHighDpiScaleFactorRoundingPolicy(
        Qt.HighDpiScaleFactorRoundingPolicy.PassThrough)
    QApplication.setAttribute(Qt.AA_EnableHighDpiScaling)
    QApplication.setAttribute(Qt.AA_UseHighDpiPixmaps)

    app = QApplication(sys.argv)
    w = Demo()
    w.show()
    app.exec_()

可以告诉我如何修改匹配机制吗

[Zzaphkiel]

self.completer.setFilterMode(Qt.MatchContains)

[iMallpa]

self.completer.setFilterMode(Qt.MatchContains)

谢谢，不过我刚刚通过另一个人做的模糊搜索机制完成了。
