本文实例为大家分享了PySide和PyQt加载ui文件的具体实现代码,供大家参考,具体内容如下
在用PySide或PyQt的时候,经常用到要将画好的ui文件导入到代码里使用,下面是两种调入的方法:
import PyQt4.uic from PyQt4 import QtCore, QtGui MainWindowForm, MainWindowBase = PyQt4.uic.loadUiType('ui/mainwindow.ui') class MainWindow(MainWindowBase, MainWindowForm): def __init__(self, parent = None): super(MainWindow, self).__init__(parent) # setup the ui self.setupUi(self) if ( __name__ == '__main__' ): app = None if ( not app ): app = QtGui.QApplication([]) window = MainWindow() window.show() if ( app ): app.exec_()
第二种:
import PyQt4.uic from PyQt4 import QtCore, QtGui class MainWindow(QtGui.QMainWindow): def __init__(self, parent = None): super(MainWindow, self).__init__(parent) # load the ui PyQt4.uic.loadUi('ui/mainwindow.ui', self) if ( __name__ == '__main__' ): app = None if ( not app ): app = QtGui.QApplication([]) window = MainWindow() window.show() if ( app ): app.exec_()
当然如果是用PySide的话,我们可以写个专门读取ui文件的方法,将baseclass和formclass返回出去,供后面UI的类继承。
# -*- coding: utf-8 -*- from PySide import QtGui import xml.etree.ElementTree as xml from cStringIO import StringIO def load_ui_file(ui_file, type='PySide'): if type == 'PySide': import pysideuic print pysideuic parsed = xml.parse(ui_file) widget_class = parsed.find('widget').get('class') form_class = parsed.find('class').text with open(ui_file, 'r') as f: o = StringIO() frame = {} pysideuic.compileUi(f, o, indent=0) pyc = compile(o.getvalue(), '', 'exec') exec pyc in frame form_class = frame['Ui_%s' % form_class] base_class = getattr(QtGui, widget_class) return form_class, base_class elif type == 'PyQt4': import PyQt4.uic return PyQt4.uic.loadUiType(ui_file) if __name__ == "__main__": ui_file = 'test.ui' load_ui_file(ui_file)
这样Pyside和PyQt就可以调用.ui文件了,而且这两种调用方法的性能和占用的内存都有人专门测试过,但作者也比较推荐第一种方法。
