用py2exe打包pyQt4

参考 http://www.linjunhalida.com/article/pyqt%E7%BC%96%E5%86%99%E7%9A%84%E7%A8%8B%E5%BA%8F%E5%A6%82%E4%BD%95%E5%8F%91%E5%B8%83
main.py:

#!/usr/bin/python
# coding=utf8

import sys
from PyQt4.QtGui import QWidget, QLabel, QLineEdit, QHBoxLayout , QApplication
from PyQt4.QtCore import *   #不加py2exe时会报缺QtCore模块的错误

app = QApplication(sys.argv)

w = QWidget()
label = QLabel("Name:")
w.resize(250, 150)
w.move(300, 300)
editor = QLineEdit()
layout = QHBoxLayout(w)
layout.addWidget(label)
layout.addWidget(editor)
w.show()

sys.exit(app.exec_())

setup.py:

# coding=utf8
# setup.py

from distutils.core import setup
import py2exe,glob

script = [{
    "script" : "src/main.py",
    "icon_resources": [(1, "res/app.ico")]
    }]

py2exe_options = {
        "compressed":1, #大大减小体积,upx无法替代
        "optimize":2,
        "bundle_files":2, #所有dll,pyd都打包到exe
        "dll_excludes":["MSVCP90.dll"],
        "includes":["sip"]
        }

files=[
("res", glob.glob("res/*.*")),
(".",glob.glob("dlls/*.*")),
]

setup(
        windows=script,
        data_files=files,
        options={'py2exe':py2exe_options},
        zipfile=None, #不生成libraray.zip
        )

必须附加的捆绑DLL: dlls ( Microsoft.VC90.CRT.manifest msvcp90.dll msvcr90.dll)

在win下配置所需环境环境并生成exe

1. 安装python
2. 安装py2exe
3. 安装pyqt4
4. 设置python的环境变量
5. 在setup.py所在目录运行下面的bat脚本
   make.bat

   python setup.py py2exe
   rmdir  /S /Q build
   dist\main.exe
   

技巧

tree实现多栏列表

• 创建

  def buildList(self):
  
    m = MyTreeWidget(self)
    m.setColumnCount(2)
    sl = QStringList()
    sl.append('id')
    sl.append(u'值')
    m.setHeaderLabels(sl)
  
    global qFrame
    attrs = qFrame.client.showarea.curPic[0].attrs
    for attr in attrs:
        sid = str(attr[0]) + ' ' + qFrame.proj.attrVerbose(attr[0])
  
        sl = QStringList()
        sl.append(sid)
        sl.append(str(attr[1]))
  
        item=QTreeWidgetItem(sl)
        item.setFlags(item.flags()|Qt.ItemIsEditable)
        m.addTopLevelItem(item)
  
    return m
  

• 读取

  item = self.list.topLevelItem(0)
  while item:
    s1 = unicode(item.text(0))
    s2 = unicode(item.text(1))
    if s1 and s2:
        try:
            id = int(s1.split()[0]) #取id
            v = int(s2)
            attrs.append((id,v))
        except ValueError:
            QMessageBox.critical(self,'X',u'请输入整数')
            return
  
    item = self.list.itemBelow(item)
  

右键删除菜单

class MyTreeWidget(QTreeWidget):

    def __init__(self,parent=None):
        super(MyTreeWidget, self).__init__(parent)

        self.itemPressed.connect(self.click)

    def click(self,item,index):

        if qApp.mouseButtons() == Qt.RightButton:
            m=QMenu()
            ac=QAction(u'删除',item.treeWidget())
            ac.triggered.connect(self.delete)
            m.addAction(ac)
            m.exec_(QCursor.pos())

    def delete(self):

        self.takeTopLevelItem(self.indexOfTopLevelItem(self.currentItem()))

双击某一栏不出现可编辑

class PathTreeWidget(MyTreeWidget):

    def __init__(self,parent=None):
        super(PathTreeWidget, self).__init__(parent)

        self.itemDoubleClicked.connect(self.dclick)

    def dclick(self,item,index):

        if index == 1:
            default = config.cfg['lastimgdir']
            fname = unicode(QtGui.QFileDialog.getOpenFileName(self, u'选择图片...',default))
            if fname:
                config.cfg['lastimgdir'] = os.path.dirname(fname)[:]
                item.setText(1,fname)
        else:
            #防止index=1时出现麻烦的可编辑,添加item时不要添加editable的flag
            item.setFlags(item.flags()|Qt.ItemIsEditable)
            self.editItem(item,index)
            item.setFlags(item.flags() & ~Qt.ItemIsEditable )
