Introduction

Ce sont des extraits de code utiles lors de création d'interfaces avec PySide.

Pour plus d'informations sur la création d'interfaces complètes, voir Création d'interface avec des fichiers UI.

Quelques commandes utiles

# Here the code to display the icon on the '''pushButton''', 
# change the name to another button, ('''radioButton, checkBox''') as well as the path to the icon,

       # Displays an icon on the button PushButton
       # self.image_01 = "C:\Program Files\FreeCAD0.13\icone01.png" # he 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


# path = FreeCAD.ConfigGet("UserAppData") # gives the user path
  path = FreeCAD.ConfigGet("AppHomePath") # gives the installation path of FreeCAD

# This command reverses the horizontal button, right to left
self.pushButton.setLayoutDirection(QtCore.Qt.RightToLeft) # This command reverses the horizontal button

# Displays an info button
self.pushButton.setToolTip(_translate("MainWindow", "Quitter la fonction", None)) # Displays an info button

# This function gives a color button
self.pushButton.setStyleSheet("background-color: red") # This function gives a color button

# This function gives a color to the text of the button
self.pushButton.setStyleSheet("color : #ff0000") # This function gives a color to the text of the button

# combinaison des deux, bouton et texte
self.pushButton.setStyleSheet("color : #ff0000; background-color : #0000ff;" ) #  combination of the two, button, and text

# replace the icon in the main window
MainWindow.setWindowIcon(QtGui.QIcon('C:\Program Files\FreeCAD0.13\View-C3P.png'))

# connects a lineEdit on execute
self.lineEdit.returnPressed.connect(self.execute) # connects a lineEdit on "def execute" after validation on enter
# self.lineEdit.textChanged.connect(self.execute) # connects a lineEdit on "def execute" with each keystroke on the keyboard

# display text in a lineEdit
self.lineEdit.setText(str(val_X)) # Displays the value in the lineEdit (convert to string)

# extract the string contained in a lineEdit
 val_X = self.lineEdit.text() # extract the (string) string contained in lineEdit
 val_X = float(val_X0)        # converted the string to an floating
 val_X = int(val_X0)          # convert the string to an integer

# This code allows you to change the font and its attributes
       font = QtGui.QFont()
       font.setFamily("Times New Roman")
       font.setPointSize(10)
       font.setWeight(10)
       font.setBold(True) # same result with tags "<b>your text</b>" (in quotes)
       self.label_6.setFont(font)
       self.label_6.setObjectName("label_6")
       self.label_6.setStyleSheet("color : #ff0000") # This function gives a color to the text
       self.label_6.setText(_translate("MainWindow", "Select a view", None))

Problèmes d'encodage

UTF8

En utilisant les caractères accentués, dans le cas ou vous obtenez les erreurs suivantes:

UnicodeDecodeError: 'utf8' codec can't decode bytes in position 0-2: invalid data

Plusieurs solutions sont possibles.

# conversion from a lineEdit
App.activeDocument().CopyRight.Text = str(unicode(self.lineEdit_20.text() , 'ISO-8859-1').encode('UTF-8'))
DESIGNED_BY = unicode(self.lineEdit_01.text(), 'ISO-8859-1').encode('UTF-8')

or with the procedure

def utf8(unio):
    return unicode(unio).encode('UTF8')

ASCII

UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 9: ordinal not in range(128)
# conversion
a = u"Nom de l'élément : "
f.write('''a.encode('iso-8859-1')'''+str(element_)+"\n")

or with the procedure

def iso8859(encoder):
    return unicode(encoder).encode('iso-8859-1')

or

iso8859(unichr(176))

or

unichr(ord(176))

or

uniteSs = "mm"+iso8859(unichr(178))
print(unicode(uniteSs, 'iso8859'))
