PySide和PyQt加载ui文件的两种方法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(), '<string>' , '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。
