使用Qt Designer为PySide设计用户界面

Qt Designer中文名：Qt设计师，是一个可视化GUI设计工具。可以帮助我们加快编写Qt程序的速度。Qt Designer可以将设计好的用户界面保存为.ui文件，其实是XML格式的文本文件。

为了在PySide使用.ui文件，我们需要通过工具pyside-uic将.ui文件转换为.py文件，然后将转换后的.py文件引入我们自己的代码中。

下面是一个实际的例子，首先在Qt Designer中设计一个对话框，名为GoToCellDialog，并另存为 gotocelldialog.ui。

gotocelldialog.ui文件内容：

<ui version="4.0"> <class>GoToCellDialogclass> <widget class="QDialog" name="GoToCellDialog">  <property name="geometry">   <rect>    <x>0x>    <y>0y>    <width>226width>    <height>70height>   rect>  property>  <property name="windowTitle">   <string>Go to Cellstring>  property>  <widget class="QLineEdit" name="lineEdit">   <property name="geometry">    <rect>     <x>98x>     <y>8y>     <width>119width>     <height>20height>    rect>   property>  widget>  <widget class="QLabel" name="label">   <property name="geometry">    <rect>     <x>8x>     <y>8y>     <width>84width>     <height>20height>    rect>   property>   <property name="text">    <string>&Cell Location:string>   property>   <property name="buddy">    <cstring>lineEditcstring>   property>  widget>  <widget class="QPushButton" name="okButton">   <property name="geometry">    <rect>     <x>58x>     <y>38y>     <width>77width>     <height>25height>    rect>   property>   <property name="text">    <string>Okstring>   property>  widget>  <widget class="QPushButton" name="cancelButton">   <property name="geometry">    <rect>     <x>141x>     <y>38y>     <width>77width>     <height>25height>    rect>   property>   <property name="text">    <string>Cancelstring>   property>  widget> widget> <resources/> <connections/>

接下来使用pyside-uic转换.ui文件：

pyside-uic gotocelldialog.ui -o gotocelldialog_ui.py

gotocelldialog_ui.py文件内容：




# -*- coding: utf-8 -*-# Form implementation generated from reading ui file 'gotocelldialog.ui'## Created: Wed Oct 27 17:13:19 2010#      by: PySide uic UI code generator## WARNING! All changes made in this file will be lost!from PySide import QtCore, QtGui
class Ui_GoToCellDialog(object):    def setupUi(self, GoToCellDialog):        GoToCellDialog.setObjectName("GoToCellDialog")        GoToCellDialog.resize(226, 70)        self.lineEdit = QtGui.QLineEdit(GoToCellDialog)        self.lineEdit.setGeometry(QtCore.QRect(98, 8, 119, 20))        self.lineEdit.setObjectName("lineEdit")        self.label = QtGui.QLabel(GoToCellDialog)        self.label.setGeometry(QtCore.QRect(8, 8, 84, 20))        self.label.setObjectName("label")        self.okButton = QtGui.QPushButton(GoToCellDialog)        self.okButton.setGeometry(QtCore.QRect(58, 38, 77, 25))        self.okButton.setObjectName("okButton")        self.cancelButton = QtGui.QPushButton(GoToCellDialog)        self.cancelButton.setGeometry(QtCore.QRect(141, 38, 77, 25))        self.cancelButton.setObjectName("cancelButton")        self.label.setBuddy(self.lineEdit)
        self.retranslateUi(GoToCellDialog)        QtCore.QMetaObject.connectSlotsByName(GoToCellDialog)
    def retranslateUi(self, GoToCellDialog):        GoToCellDialog.setWindowTitle(QtGui.QApplication.translate("GoToCellDialog", "Go to Cell", None, QtGui.QApplication.UnicodeUTF8))        self.label.setText(QtGui.QApplication.translate("GoToCellDialog", "&Cell Location:", None, QtGui.QApplication.UnicodeUTF8))        self.okButton.setText(QtGui.QApplication.translate("GoToCellDialog", "Ok", None, QtGui.QApplication.UnicodeUTF8))        self.cancelButton.setText(QtGui.QApplication.translate("GoToCellDialog", "Cancel", None, QtGui.QApplication.UnicodeUTF8))

然后编写代码，引用gotocelldialog_ui.py，并显示GoToCellDialog。代码如下：




 1 #!/usr/bin/env python 2   3  import sys 4  5  from PySide.QtCore import* 6  from PySide.QtGui import* 7  8  from gotocelldialog_ui import Ui_GoToCellDialog 9 10  class GoToCellDialog(QDialog):11 def__init__(self, parent=None):12         QDialog.__init__(self, parent)13 14         self.ui= Ui_GoToCellDialog()15         self.ui.setupUi(self)16 17  def main():18     app = QApplication(sys.argv)19     d = GoToCellDialog()20     d.show()21     sys.exit(app.exec_())22 23  if__name__== '__main__':24     main()
