在下面的示例中,我想用打开 Qdialog 的文件填充我的 QListWidget。我不明白如何添加列表中选择的文件。我应该上一门新课吗?如何连接 setupList 和 addFiles 这两个方法?
import sys
from PyQt4 import QtCore, QtGui
from datapath import *

def __init__(self):
super(MainWindow,self).__init__()
self.sources =[]
self.setupActions()
self.setupList()
self.setupUi()
self.setupStatusBars()
def addFiles(self):
files = QtGui.QFileDialog.getOpenFileNames(
self,"Open File", dirpath, "txt Files (*.txt)")
for string in files:
self.sources.append(str(string))
return self.sources
def setupActions(self):
self.exitAct = QtGui.QAction(
QtGui.QIcon(':/images/exit.png'),
"E&xit", self, shortcut="Ctrl+Q",
statusTip="Exit the application", triggered=self.close
)
self.addFilesAct = QtGui.QAction(
QtGui.QIcon(':/images/open.png'),
"Add &Files", self, shortcut=QtGui.QKeySequence.Open,
statusTip="Open an existing file", triggered=self.addFiles
)
def setupList(self):
#FileList
self.FileList = QtGui.QListWidget(self)
self.FileList.addItems(self.sources)
def setupUi(self):
#Window size
horiz = 300
vert = 300
self.setGeometry(self.width()/2, self.height()/2,horiz,vert)
self.setWindowTitle("test")
#MenuBar
self.FileMenu = self.menuBar().addMenu("&File")
self.FileMenu.addAction(self.addFilesAct)
self.FileMenu.addSeparator();
self.FileMenu.addAction(self.exitAct)
#ToolBar
self.fileToolBar = self.addToolBar("Open")
self.fileToolBar.addAction(self.addFilesAct)
self.fileToolBar.setIconSize(QtCore.QSize(64,64))
#Build Layout
mainLayout = QtGui.QVBoxLayout()
mainLayout.addWidget(self.FileList)
widget = QtGui.QWidget()
widget.setLayout(mainLayout)
self.setCentralWidget(widget)
def setupStatusBars(self):
self.statusBar().showMessage("Ready")
def main():
app = QtGui.QApplication(sys.argv)
mw = MainWindow()
mw.show()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
