Dialog creation with various widgets

Introduction

This is an example of dialog creation with PySide.

In this example, the entire interface is defined in Python. Although this is possible for small interfaces, for larger interfaces the recommendation is to create .ui files through Qt Designer, and load these in the program.

Method 1

An example of a dialog box complete with its connections.

Here the code to display the icon on the pushButton, change the name for another button, (radioButton, checkBox) and the path to the icon.

        # Affiche un icône sur le bouton PushButton
        # self.image_01 = "C:\Program Files\FreeCAD0.13\icone01.png" # the name of the icon
        self.image_01 = path+"icone01.png" # the name of the icon
        icon01 = QtGui.QIcon() 
        icon01.addPixmap(QtGui.QPixmap(self.image_01),QtGui.QIcon.Normal, QtGui.QIcon.Off)
        self.pushButton.setIcon(icon01) 
        self.pushButton.setLayoutDirection(QtCore.Qt.RightToLeft) # This command reverses the direction of the button

The command UserAppData gives the user path AppHomePath gives the installation path of FreeCAD

#        path = FreeCAD.ConfigGet("UserAppData")
        path = FreeCAD.ConfigGet("AppHomePath")
``` This command reverses the horizontal button, right to left.

 
```python
self.pushButton.setLayoutDirection(QtCore.Qt.RightToLeft) # This command reverses the direction of the button

Method 2

Another method to display a window, here by creating a file QtForm.py which contains the header program (module called with import QtForm), and a second module that contains the code window all these accessories, and your code (the calling module).

This method requires two separate files, but allows to shorten your program using the file ' ' QtForm.py ' ' import. Then distribute the two files together, they are inseparable.

The file QtForm.py

class Form(object):
   def __init__(self, title, width, height):
      self.window = QtGui.QMainWindow()
      self.title=title
      self.window.setObjectName(_fromUtf8(title))
      self.window.setWindowTitle(_translate(self.title, self.title, None))
      self.window.resize(width, height)

   def show(self):
      self.createUI()
      self.retranslateUI()
      self.window.show()
   
   def setText(self, control, text):
      control.setText(_translate(self.title, text, None))
``` The calling file that contains the window and your code.

The file my_file.py

The connections are to do, a good exercise.  
```python

# -*- coding: utf-8 -*-
# Create by flachyjoe
from PySide import QtCore, QtGui
import QtForm

class myForm(QtForm.Form):
   def createUI(self):
      self.centralWidget = QtGui.QWidget(self.window)
      self.window.setCentralWidget(self.centralWidget)
      
      self.pushButton = QtGui.QPushButton(self.centralWidget)
      self.pushButton.setGeometry(QtCore.QRect(30, 170, 93, 28))
      self.pushButton.clicked.connect(self.on_pushButton_clicked)
      
      self.lineEdit = QtGui.QLineEdit(self.centralWidget)
      self.lineEdit.setGeometry(QtCore.QRect(30, 40, 211, 22))
      
      self.checkBox = QtGui.QCheckBox(self.centralWidget)
      self.checkBox.setGeometry(QtCore.QRect(30, 90, 81, 20))
      self.checkBox.setChecked(True)
      
      self.radioButton = QtGui.QRadioButton(self.centralWidget)
      self.radioButton.setGeometry(QtCore.QRect(30, 130, 95, 20))
   
   def retranslateUI(self):
      self.setText(self.pushButton, "Fermer")
      self.setText(self.lineEdit, "essais de texte")
      self.setText(self.checkBox, "CheckBox")
      self.setText(self.radioButton, "RadioButton")
   
   def on_pushButton_clicked(self):
      self.window.hide()
