滑动条添加工具提示

我刚才更新了 ToolTip 的代码，现在它是顶层窗口了，拉取更新后，你可以使用下述代码实现一个带工具提示的滑动条：

# coding:utf-8
from PyQt5.QtCore import Qt, pyqtSignal, QPoint, QSize
from PyQt5.QtGui import QMouseEvent
from PyQt5.QtWidgets import QSlider

from tool_tip import ToolTip


class Slider(QSlider):
    """ A slider which can be clicked """

    clicked = pyqtSignal()

    def __init__(self, orient, parent=None):
        super().__init__(orient, parent=parent)
        self._toolTip = ToolTip('0', self)

    def mousePressEvent(self, e: QMouseEvent):
        super().mousePressEvent(e)
        if self.orientation() == Qt.Horizontal:
            value = int(e.pos().x() / self.width() * self.maximum())
        else:
            value = int((self.height()-e.pos().y()) /
                        self.height() * self.maximum())

        self.setValue(value)
        self.clicked.emit()

    def mouseMoveEvent(self, e):
        super().mouseMoveEvent(e)
        self._toolTip.setText(str(self.value()))
        if self.isSliderDown():
            pos = self.mapToGlobal(QPoint())
            pos.setX(pos.x() + e.x() - 13)
            self._toolTip.adjustPos(pos, QSize(26, 26))
            self._toolTip.show()

但是把滑动条把手移到最左端之后终端会报警：

UpdateLayeredWindowIndirect failed for ptDst=(857, 464), size=(68x61), dirty=(66x70 1, -2) (参数错误。)

暂时没想到解决办法，所以我没把这个滑动条一起提交了
