最近学习pyqt,在网上搜索到了做Google map的,发现那个使用图片作为显示的,感觉那样很不方便,所以想以HTML显示.运用pyqt4的QWebView显示
第一步申请Google map api key,然后进行开发.
第二步,写个运用Google map api进行解析的工具 GoogleMapsUtil.py.代码如下:

import urllib

GMap_KEY_ID = 'YOUR GOOGLE MAP API KEY'

def getGMapsGEO(qaddr):
     geo_url = 'http://maps.google.com/maps/geo?'+urllib.urlencode({'q':qaddr})+'&output=csv&key='+GMap_KEY_ID
     gdata = urllib.urlopen(geo_url)
     gdataArray = gdata.read().split(',')
     return gdataArray

def getGMapsStaticUrl(Latitudes, Longitudes, zoom=14, width=512, height=512):
     #print "--"+str(Latitudes)+"--"+str(Longitudes)+"--"+str(zoom)
     map_url = 'http://maps.google.com/staticmap?center='+str(Latitudes)+','+str(Longitudes)+'&zoom='+str(zoom)+
         '&size='+str(width)+'x'+str(height)+'&maptype=mobile&key='+GMap_KEY_ID+'&sensor=false'
     return map_url

第三步,用qt designer拉出界面,然后转化为python代码,Ui_GoogleMaps.py 代码如下:

from PyQt4 import QtCore, QtGui

class Ui_DialogGoogleMaps(object):
    def setupUi(self, DialogGoogleMaps):
        DialogGoogleMaps.setObjectName("DialogGoogleMaps")
        DialogGoogleMaps.resize(773, 588)
        self.inputAddress = QtGui.QLineEdit(DialogGoogleMaps)
        self.inputAddress.setGeometry(QtCore.QRect(40, 30, 371, 20))
        self.inputAddress.setObjectName("inputAddress")
        self.labelAddress = QtGui.QLabel(DialogGoogleMaps)
        self.labelAddress.setGeometry(QtCore.QRect(10, 30, 31, 16))
        self.labelAddress.setObjectName("labelAddress")
        self.groupBoxMapCtrl = QtGui.QGroupBox(DialogGoogleMaps)
        self.groupBoxMapCtrl.setGeometry(QtCore.QRect(530, 40, 211, 121))
        self.groupBoxMapCtrl.setObjectName("groupBoxMapCtrl")
        self.ButtonUp = QtGui.QPushButton(self.groupBoxMapCtrl)
        self.ButtonUp.setGeometry(QtCore.QRect(90, 10, 31, 31))
        self.ButtonUp.setObjectName("ButtonUp")
        self.ButtonDown = QtGui.QPushButton(self.groupBoxMapCtrl)
        self.ButtonDown.setGeometry(QtCore.QRect(90, 90, 31, 31))
        self.ButtonDown.setObjectName("ButtonDown")
        self.ButtonLeft = QtGui.QPushButton(self.groupBoxMapCtrl)
        self.ButtonLeft.setGeometry(QtCore.QRect(30, 50, 31, 31))
        self.ButtonLeft.setObjectName("ButtonLeft")
        self.ButtonRight = QtGui.QPushButton(self.groupBoxMapCtrl)
        self.ButtonRight.setGeometry(QtCore.QRect(150, 50, 31, 31))
        self.ButtonRight.setObjectName("ButtonRight")
        self.ButtonZoom = QtGui.QPushButton(self.groupBoxMapCtrl)
        self.ButtonZoom.setGeometry(QtCore.QRect(70, 50, 31, 31))
        self.ButtonZoom.setObjectName("ButtonZoom")
        self.ButtonNarrow = QtGui.QPushButton(self.groupBoxMapCtrl)
        self.ButtonNarrow.setGeometry(QtCore.QRect(110, 50, 31, 31))
        self.ButtonNarrow.setObjectName("ButtonNarrow")
        self.MapView = QtWebKit.QWebView(DialogGoogleMaps)
        self.MapView.setGeometry(QtCore.QRect(10, 60, 512, 512))
        self.MapView.setUrl(QtCore.QUrl("http://maps.google.com/staticmap?center=32.0583650,118.7964680&zoom=14&size=512x512&maptype=mobile&markers=32.0583650,118.7964680&key=ABQIAAAApIB1Ubv-TkAKBJ37W0Hh2RS1AC4DxUbsxJ-9A5H8anlW8PhTrBQW71UJo3SK1Lm1LK_DZxfeCJessA&sensor=false"))
        self.MapView.setObjectName("MapView")
        self.BtnSearch = QtGui.QPushButton(DialogGoogleMaps)
        self.BtnSearch.setGeometry(QtCore.QRect(440, 30, 75, 23))
        self.BtnSearch.setObjectName("BtnSearch")
        self.ListAddress = QtGui.QListWidget(DialogGoogleMaps)
        self.ListAddress.setGeometry(QtCore.QRect(530, 200, 211, 371))
        self.ListAddress.setFrameShape(QtGui.QFrame.StyledPanel)
        self.ListAddress.setObjectName("ListAddress")
        QtGui.QListWidgetItem(self.ListAddress)
        QtGui.QListWidgetItem(self.ListAddress)
        self.label = QtGui.QLabel(DialogGoogleMaps)
        self.label.setGeometry(QtCore.QRect(530, 180, 54, 14))
        self.label.setObjectName("label")

        self.retranslateUi(DialogGoogleMaps)
        QtCore.QMetaObject.connectSlotsByName(DialogGoogleMaps)

    def retranslateUi(self, DialogGoogleMaps):
        DialogGoogleMaps.setWindowTitle(QtGui.QApplication.translate("DialogGoogleMaps", "Google maps应用程序", None, QtGui.QApplication.UnicodeUTF8))
        self.labelAddress.setText(QtGui.QApplication.translate("DialogGoogleMaps", "地址:", None, QtGui.QApplication.UnicodeUTF8))
        self.groupBoxMapCtrl.setTitle(QtGui.QApplication.translate("DialogGoogleMaps", "地图控制", None, QtGui.QApplication.UnicodeUTF8))
        self.ButtonUp.setText(QtGui.QApplication.translate("DialogGoogleMaps", "上", None, QtGui.QApplication.UnicodeUTF8))
        self.ButtonDown.setText(QtGui.QApplication.translate("DialogGoogleMaps", "下", None, QtGui.QApplication.UnicodeUTF8))
        self.ButtonLeft.setText(QtGui.QApplication.translate("DialogGoogleMaps", "左", None, QtGui.QApplication.UnicodeUTF8))
        self.ButtonRight.setText(QtGui.QApplication.translate("DialogGoogleMaps", "右", None, QtGui.QApplication.UnicodeUTF8))
        self.ButtonZoom.setText(QtGui.QApplication.translate("DialogGoogleMaps", "大", None, QtGui.QApplication.UnicodeUTF8))
        self.ButtonNarrow.setText(QtGui.QApplication.translate("DialogGoogleMaps", "小", None, QtGui.QApplication.UnicodeUTF8))
        self.BtnSearch.setText(QtGui.QApplication.translate("DialogGoogleMaps", "搜索", None, QtGui.QApplication.UnicodeUTF8))
        self.ListAddress.setSortingEnabled(False)
        __sortingEnabled = self.ListAddress.isSortingEnabled()
        self.ListAddress.setSortingEnabled(False)
        self.ListAddress.item(0).setText(QtGui.QApplication.translate("DialogGoogleMaps", "结果1", None, QtGui.QApplication.UnicodeUTF8))
        self.ListAddress.item(1).setText(QtGui.QApplication.translate("DialogGoogleMaps", "新建项目", None, QtGui.QApplication.UnicodeUTF8))
        self.ListAddress.setSortingEnabled(__sortingEnabled)
        self.label.setText(QtGui.QApplication.translate("DialogGoogleMaps", "搜索结果:", None, QtGui.QApplication.UnicodeUTF8))

from PyQt4 import QtWebKit

if __name__ == "__main__":
    import sys
    app = QtGui.QApplication(sys.argv)
    DialogGoogleMaps = QtGui.QDialog()
    ui = Ui_DialogGoogleMaps()
    ui.setupUi(DialogGoogleMaps)
    DialogGoogleMaps.show()
    sys.exit(app.exec_())

第四步:写界面的动作插槽,GoogleMapsExec.py,代码如下:

第五步:这样你运行一下就可以看到最终的成果了.如图.呵呵:

可以在地址框里输入查询的地址,这个程序还没有完善好.怕自己忘记先记录下来吧.等有时间在加以完善.源代码在我的附件里.呵呵

googlemapsapp_pyqt4.zip

下载了中文包eric4-i18n-zh_CN.GB2312-4.3.6.zip,解压后,安装一闪,在Interface的语言设置里却没有中文选项。不用说没有安装成功.
上 网所了一下资料,手动将i18n目录下的eric4_zh_CN.GB2312.qm和eric4_zh_CN.GB2312.ts拷贝到 C:Python25Libsite-packageseric4i18n,然后在Interface的语言设置里有中文选项了.选中 ->应用->重启.然后就是以中文启动了.下面提供Eric4的中文包下载
