今回はQComboboxのオシャレなデザインサンプルを4種類紹介します。QSSコードとClassをコピペすればそのまま使うことができます。もちろん自分好みにカスタマイズして使って頂いても構いません。

この記事で紹介するQComboBoxはどれも以下のクラスを使っています。

class CustomeComboBox(QComboBox):
    def __init__(self, parent=None, *args, **kwargs):
        super(CustomeComboBox, self).__init__(parent, *args, **kwargs)
        self.__PopupOffcet = (0, 0)
        self.__fade = False
        self.__stretch = False
        self.__slide = False
        self.popup = self.view().window()

    @ property
    def PopupOffcet(self):
        pass

    @ PopupOffcet.getter
    def PopupOffcet(self):
        return self.__PopupOffcet

    @ PopupOffcet.setter
    def PopupOffcet(self, value):
        self.__PopupOffcet = value

    @ property

        pass

    @ fade.getter
    def fade(self):
        return self.__fade

        pass

    @ stretch.getter
    def stretch(self):
        return self.__stretch

    @ stretch.setter
    def stretch(self, value):
        self.__stretch = value

    @ property
    def slide(self):
        pass

    @ slide.getter

            self.rect.x() + self.__PopupOffcet[0],
            self.rect.y() + self.__PopupOffcet[1]
        )

            if not finished:
                self.opasicyAnimationtion.finished.connect(self.finishedPopup)
                finished = True
        if self.__slide:
            self.slideWindowAnimation(start=0, end=10, duration=300, object=self.popup)
            if not finished:

        animationStyle=None, finishAction=None, windowAnim=True,
        startCurveType=QEasingCurve.OutCubic,
        endCurveType=QEasingCurve.InCubic,
    ):
        geo = object.geometry()
        self.stretchAnimation = QPropertyAnimation(object, bsize, object)
        self.stretchAnimation.setDuration(duration)
        style = QEasingCurve()
        if start >= end:
            style.setType(endCurveType)
        else:
            style.setType(startCurveType)
        if animationStyle is not None:
            style.setType(animationStyle)
        self.stretchAnimation.setEasingCurve(style)
        self.stretchAnimation.setStartValue(QSize(geo.width(), start))

        self.stretchAnimation.start()

    def slideWindowAnimation(
        self, start=-100, end=0, duration=300, object=None,
        animationStyle=None, finishAction=None, windowAnim=True,
        startCurveType=QEasingCurve.OutCubic,
        endCurveType=QEasingCurve.InCubic,
    ):
        pos = object.pos()
        self.slideAnimation = QPropertyAnimation(object, bpos, object)
        self.slideAnimation.setDuration(duration)
        style = QEasingCurve()
        if start >= end:
            style.setType(endCurveType)
        else:
            style.setType(startCurveType)
        if animationStyle is not None:
            style.setType(animationStyle)
        self.slideAnimation.setEasingCurve(style)
        self.slideAnimation.setStartValue(QPoint(pos.x(), pos.y() + start))

        self.slideAnimation.start()

    def fadeWindowAnimation(

        self.opasicyAnimationtion.setStartValue(start)
        self.opasicyAnimationtion.setEndValue(end)
        self.opasicyAnimationtion.start()

このクラスはQComboBoxのpopupにオフセットやアニメーションをつけれるようにQComboBoxを継承したものになります

また、実行するUIは基本的に以下のコードになっています

class GUI(QFrame):
    def __init__(self, parent=None, *args, **kwargs):
        super(GUI, self).__init__(parent, *args, **kwargs)
        self.setWindowTitle(Qss template)
        self.resize(300, 230)

        self.ComboBox_ListView = QListView(self)
        self.ComboBox_ListView.setObjectName(ComboBox)
        self.ComboBox_ListView.setVerticalScrollBarPolicy( Qt.ScrollBarAlwaysOff ) 
        self.ComboBox = CustomeComboBox(self)
        self.ComboBox.setView(self.ComboBox_ListView)
        self.ComboBox.setObjectName(ComboBox)
        self.ComboBox.setEditable(True)
        self.ComboBox.lineEdit().setObjectName(ComboBox)
        self.ComboBox.lineEdit().setReadOnly(True)
        self.ComboBox.PopupOffcet = (0, 10)
        self.ComboBox.fade = True
        self.ComboBox.slide = True
        self.ComboBox.stretch = True
        self.ComboBox.setGeometry(50, 30, 200, 25)
        for i in range(5):
            self.ComboBox.addItem(Item %s % i)

        self.setStyleSheet(
        # ここにcopy&paste
        )

def main():
    app = QApplication.instance()
    gui = GUI()
    gui.show()
    sys.exit()
    app.exec_()

if __name__ == '__main__':
    main()

25行目の# ここにcopy&pasteの部分にQSSをコピペすると同じものを作成できます
また、下のコードの部分をTrueかFalseにすることでアニメーションに変化を与えています

self.ComboBox.fade = True
self.ComboBox.slide = True
self.ComboBox.stretch = True

スタイルシートに使用するイメージと同じものを使用したい場合は
ここからimageResource.pyをダウンロードして使用してください
PYTHONPATH直下であれば下のコードで問題ないはずです

import os
import sys
import imageResource

from PySide2.QtGui import*
from PySide2.QtCore import*
