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：
代码
<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
<class>GoToCellDialog</class>
<widget class="QDialog" name="GoToCellDialog">
<property name="geometry">
<rect>
<x>0</x>
<y>0</y>
<width>226</width>
<height>70</height>
</rect>
</property>
<property name="windowTitle">
<string>Go to Cell</string>
</property>
<widget class="QLineEdit" name="lineEdit">
<property name="geometry">
<rect>
<x>98</x>
<y>8</y>
<width>119</width>
<height>20</height>
</rect>
</property>
</widget>
<widget class="QLabel" name="label">
<property name="geometry">
<rect>
<x>8</x>
<y>8</y>
<width>84</width>
<height>20</height>
</rect>
</property>
<property name="text">
<string>&Cell Location:</string>
</property>
<property name="buddy">
<cstring>lineEdit</cstring>
</property>
</widget>
<widget class="QPushButton" name="okButton">
<property name="geometry">
<rect>
<x>58</x>
<y>38</y>
<width>77</width>
<height>25</height>
</rect>
</property>
<property name="text">
<string>Ok</string>
</property>
</widget>
<widget class="QPushButton" name="cancelButton">
<property name="geometry">
<rect>
<x>141</x>
<y>38</y>
<width>77</width>
<height>25</height>
</rect>
</property>
<property name="text">
<string>Cancel</string>
</property>
</widget>
</widget>
<resources/>
<connections/>
</ui>
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：
代码
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'gotocelldialog.ui'
#
# Created: Wed Oct 27 17:13:19 2010

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：
代码
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()
最终的效果图：
