我有一个应用程序,需要在10英寸触摸屏上运行。我尝试将QSlider的手柄更大,以便更容易移动。我找到了很多在样式表中更改手柄宽度的例子,但是当我运行代码时,更改并没有反映出来。我正在使用PyQt5 Designer,并且这是滑块的样式表。
QSlider::groove:horizontal {height: 10px; margin: 0 0;}
QSlider::handle:horizontal {background-color: black; border: 1px; height:
40px; width: 40px; margin: 0 0;}
以下是主程序:
from Slidertest import Ui_MainWindow
import sys
from PyQt5.QtWidgets import QApplication, QMainWindow
class RPTApp(QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
super(RPTApp, self).__init__(parent)
self.setupUi(self)
def main():
app = QApplication(sys.argv)
window = RPTApp()
window.show()
app.exec_()
if __name__ == '__main__':
main()
以下是滑块的设计代码:
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(640, 480)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.PS_timeSlider = QtWidgets.QSlider(self.centralwidget)
self.PS_timeSlider.setGeometry(QtCore.QRect(100, 100, 371, 50))
sizePolicy = QtWidgets.QSizePolicy(QtWidgets.QSizePolicy.Expanding,
QtWidgets.QSizePolicy.Expanding)
sizePolicy.setHorizontalStretch(0)
sizePolicy.setVerticalStretch(0)
sizePolicy.setHeightForWidth(self.PS_timeSlider.sizePolicy().
hasHeightForWidth())
#needed to add a return and break the line above
self.PS_timeSlider.setSizePolicy(sizePolicy)
self.PS_timeSlider.setBaseSize(QtCore.QSize(0, 0))
font = QtGui.QFont()
font.setPointSize(12)
font.setKerning(False)
self.PS_timeSlider.setFont(font)
self.PS_timeSlider.setFocusPolicy(QtCore.Qt.WheelFocus)
self.PS_timeSlider.setContextMenuPolicy(QtCore.Qt.NoContextMenu)
self.PS_timeSlider.setToolTip("")
self.PS_timeSlider.setStatusTip("")
self.PS_timeSlider.setWhatsThis("")
self.PS_timeSlider.setAccessibleName("")
self.PS_timeSlider.setAccessibleDescription("")
self.PS_timeSlider.setStyleSheet("QSlider::groove:horizontal
{height: 10px; margin: 0 0;}\n"
"QSlider::handle:horizontal {background-color: black; border: 1px; height:
40px; width: 40px; margin: 0 0;}\n"
"")
self.PS_timeSlider.setMinimum(0)
self.PS_timeSlider.setMaximum(100)
self.PS_timeSlider.setSingleStep(1)
self.PS_timeSlider.setPageStep(5)
self.PS_timeSlider.setProperty("value", 50)
self.PS_timeSlider.setSliderPosition(50)
self.PS_timeSlider.setTracking(True)
self.PS_timeSlider.setOrientation(QtCore.Qt.Horizontal)
self.PS_timeSlider.setInvertedAppearance(False)
self.PS_timeSlider.setInvertedControls(False)
self.PS_timeSlider.setTickPosition(QtWidgets.QSlider.TicksBothSides)
self.PS_timeSlider.setTickInterval(1)
self.PS_timeSlider.setObjectName("PS_timeSlider")
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 640, 26))
self.menubar.setObjectName("menubar")
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
我已经尝试了搜索到的所有方法,但都没有成功。我会非常感激您能提供任何帮助。
