Python 从QComboBox中的样式列表使用QStyleFactory在中设置样式
我一直在使用PyQt4实现一个应用程序 在这个应用程序中,我想根据用户的选择设置样式,并且我想在不重新启动对话框的情况下设置样式 下面是我的一段代码,它影响了造型领域:Python 从QComboBox中的样式列表使用QStyleFactory在中设置样式,python,pyqt4,qcombobox,qstyle,Python,Pyqt4,Qcombobox,Qstyle,我一直在使用PyQt4实现一个应用程序 在这个应用程序中,我想根据用户的选择设置样式,并且我想在不重新启动对话框的情况下设置样式 下面是我的一段代码,它影响了造型领域: import sys from PyQt4.QtCore import * from PyQt4.QtGui import * from PyQt4 import QtGui styles = ["Plastique","Cleanlooks","CDE","Motif","GTK+"] class AppWidget(Q

class AppWidget(QWidget):
def __init__(self,parent=None):
super(AppWidget,self).__init__(parent)
global styles # declaring global
# I've skipped the useless codes
horizontalLayout = QHBoxLayout()
self.styleLabel =QLabel("Set Style:")
self.styleComboBox = QComboBox()
self.styleComboBox.addItems(styles) # adding the styles list
horizontalLayout.addWidget(self.styleLabel)
horizontalLayout.addWidget(self.styleComboBox)
# skip more code
self.setLayout(layout)
def getStyle(self):
return self.styleComboBox.currentIndex() # get the current index from combobox
# another way i also implement is :
# return self.styleComboBox.currentText()
# after that i remove the global and directly access using this method
# which is of no success
if __name__ == "__main__":
global styles # declaring global
app = QApplication(sys.argv)
widgetApp = AppWidget()
i = widgetApp.getStyle() # assign the index here
QtGui.QApplication.setStyle(QtGui.QStyleFactory.create(styles[i])) # setting the style
widgetApp.show()
app.exec_()
print i
但是我一直只得到“Plastique”样式。您不需要一个全局样式列表,因为它已经从中提供 您需要做的是将这些键加载到组合框中,将组合框索引设置为当前样式,然后将组合框
activated
信号连接到处理程序,以便可以更改样式
像这样的方法应该会奏效:
import sys
from PyQt4 import QtCore, QtGui
class AppWidget(QtGui.QWidget):
def __init__(self, parent=None):
super(AppWidget, self).__init__(parent)
horizontalLayout = QtGui.QHBoxLayout()
self.styleLabel = QtGui.QLabel("Set Style:")
self.styleComboBox = QtGui.QComboBox()
# add styles from QStyleFactory
self.styleComboBox.addItems(QtGui.QStyleFactory.keys())
# find current style
index = self.styleComboBox.findText(
QtGui.qApp.style().objectName(),
QtCore.Qt.MatchFixedString)
# set current style
self.styleComboBox.setCurrentIndex(index)
# set style change handler
self.styleComboBox.activated[str].connect(self.handleStyleChanged)
horizontalLayout.addWidget(self.styleLabel)
horizontalLayout.addWidget(self.styleComboBox)
self.setLayout(horizontalLayout)
# handler for changing style
def handleStyleChanged(self, style):
QtGui.qApp.setStyle(style)
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
widgetApp = AppWidget()
widgetApp.show()
sys.exit(app.exec_())
@LucyJaa。我已经为我添加的行添加了注释。对于
global styles
和getStyle
,您不需要示例中的任何代码。我还在一些地方添加了QtGui
(但这不会有任何区别)。除此之外,我的代码与您的示例相同。
