无法完全删除PyQt QGraphicsView的边框 [英] Unable to fully remove border of PyQt QGraphicsView

问题描述

我尝试在QGraphicsView上调用 self.setStyleSheet("background:transparent; border:transparent;")，但它在顶部边缘仍留有1像素的边界.我也尝试过用 border-style:none; 替换 border:transparent; ，但是它也不起作用.

I have tried calling self.setStyleSheet("background: transparent; border: transparent;") on a QGraphicsView, but it still leaves a 1 pixel border on the top edge. I have also tried replacing border: transparent; with border-style: none;, but it didn't work either.

以下是问题的屏幕截图:

推荐答案

您可以使用以下CSS规则之一:

You can use one of the following css rule:

graphicsView.setStyleSheet("border-width: 0px; border-style: solid")

或

graphicsView.setStyleSheet("border: 0px")

您的边框应该消失了.

import sys
from PyQt4.QtGui import *

class Ui(QWidget):

    def __init__(self, parent=None):
        QWidget.__init__(self, parent)

        graphicsView = QGraphicsView()
        graphicsView.setStyleSheet("border: 0px")

        grid = QGridLayout()
        grid.addWidget(graphicsView)

        self.setLayout(grid)

app = QApplication(sys.argv)
ui = Ui()
ui.show()
sys.exit(app.exec_())
