PyQt4文件名对话框
|
我是一个新手，所以请客气；-)
我有一个使用PyQt4和python 2.6并带有工作文件对话框的GUI（即，您单击了一个按钮，然后弹出了一个窗口，允许您选择要加载/保存的文件）。 GUI的代码就像2000行，所以我将包括我认为重要的部分：
from PyQt4 import QtGui as qt
from PyQt4 import QtCore as qc
class NuclearMotion(qt.QWidget):
def __init__(self, parent=None):
super(NuclearMotion, self).__init__(parent)
file_button = qt.QPushButton(\"Use data from file\")
mainLayout = qt.QGridLayout()
mainLayout.addWidget(file_button, 14, 8, 1, 2)
def choose_file():
file_name = qt.QFileDialog.getOpenFileName(self, \"Open Data File\", \"\", \"CSV data files (*.csv)\")
self.connect(file_button, qc.SIGNAL(\"clicked()\"), choose_file)
self.setLayout(mainLayout)
if __name__ == \'__main__\':
import sys
app = qt.QApplication(sys.argv)
NuclearMotionWidget = NuclearMotion()
NuclearMotionWidget.show()
sys.exit(app.exec_())
from PyQt4 import QtCore, QtGui
class Ui_mainLayout(object):
def setupUi(self, mainLayout):
mainLayout.setObjectName(_fromUtf8(\"mainLayout\"))
mainLayout.resize(598, 335)
mainLayout.setTabPosition(QtGui.QTabWidget.North)
mainLayout.setTabShape(QtGui.QTabWidget.Rounded)
mainLayout.setElideMode(QtCore.Qt.ElideLeft)
self.basic_tab = QtGui.QWidget()
self.file_button = QtGui.QPushButton(self.basic_tab)
QtCore.QObject.connect(self.file_button, QtCore.SIGNAL(\"clicked()\"), self.choose_file)
def choose_file(self):
file_name = QtGui.QFileDialog.getOpenFileName(self, \"Open Data File\", \"\", \"CSV data files (*.csv)\")
if __name__ == \"__main__\":
import sys
app = QtGui.QApplication(sys.argv)
mainLayout = QtGui.QTabWidget()
ui = Ui_mainLayout()
ui.setupUi(mainLayout)
mainLayout.show()
sys.exit(app.exec_())
