Keep animation/widget state on widget enter event

[tIk90wT]

I've got a widget that is revealed when a button is under mouse and it is hidden on leaveEvent of the button unless the mouse enters the revealed widget. I tried something like the following , thought it is simple but doesn't work as intended and not sure what I'm missing.

# coding=utf-8
import os
import sys

from PySide6.QtCore import *
from PySide6.QtGui import *
from PySide6.QtWidgets import *


class MainWindow(QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()

        self.main_container = QWidget(self)
        self.main_container.setGeometry(50, 0, self.width()-50, self.height())

        self.pop = QWidget(self)
        self.pop.setGeometry(-100, 0, 0, 0)
        self.pop.installEventFilter(self)
        self.pop.setStyleSheet("background: orange;")
        self.pop_anim = QPropertyAnimation(self.pop, b"geometry")
        self.pop.setObjectName("pop")

        self.but = QPushButton("H")
        self.but.setFixedHeight(50)
        self.but.setStyleSheet("background: green;")
        self.but.installEventFilter(self)
        self.but.setObjectName("but")

        self.sidebar = QWidget(self)
        self.sidebar.setGeometry(0, 0, 50, self.height())
        self.sidebar.setStyleSheet("background: black;")

        self.sidebar_lay = QHBoxLayout()
        self.sidebar_lay.setSpacing(0)
        self.sidebar_lay.setContentsMargins(0, 0, 0, 0)
        self.sidebar_lay.addWidget(self.but)
        self.sidebar_lay.setAlignment(self.but, Qt.AlignTop)
        self.sidebar.setLayout(self.sidebar_lay)

        self.resize(500, 500)

    def AnimPop(self, sx, ex, sw, ew):
        self.pop_anim.setStartValue(QRect(sx, 0, sw, 200))
        self.pop_anim.setEndValue(QRect(ex, 0, ew, 200))
        self.pop_anim.start()

    def eventFilter(self, obj, e):
        if e.type() == QEvent.Enter:
            if obj.objectName() == self.but.objectName():
                self.but.setStyleSheet("background: orange;")
                self.AnimPop(-100, 50, 100, 180)
            elif obj.objectName() == self.pop.objectName():
                self.pop.setGeometry(self.pop.geometry())

        elif e.type() == QEvent.Leave:
            if obj.objectName() == self.but.objectName():
                self.but.setStyleSheet("background: green;")
                self.AnimPop(self.pop.x(), -100, 180, 100)

        return False


if __name__ == '__main__':
    app = QApplication(sys.argv)
    mw = MainWindow()
    mw.show()
    sys.exit(app.exec_())

What I need is; the animated widget should stay in place if it is under mouse.

Hi,

You might want to rather do the hiding if the enter event is not of any of these two widgets and the widget is not already invisible.

@SGaist Something like

if e.type() == QEvent.Enter:
            if obj.objectName() == self.main_container.objectName():
              self.hidePop()
                

Am I understanding this correctly?

I would have put the hide in the else after the elif within the EnterEvent handling.
