There are a number of text conventions used throughout this book.
CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "This template creates a form whose superclass is QWidget rather than QDialog."
A block of code is set as follows:
import sys
from PyQt5.QtWidgets import QDialog, QApplication
from demoSignalSlot1 import *
class MyForm(QDialog):
def __init__(self):
super().__init__()
self.ui = Ui_Dialog()
self.ui.setupUi(self)
self.show()
if __name__=="__main__":
app = QApplication(sys.argv)
w = MyForm()
w.show()
sys.exit(app.exec_())
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
[default]
exten => s,1,Dial(Zap/1|30)
exten => s,2,Voicemail(u100)
exten => s,102,Voicemail(b100)
exten => i,1,Voicemail(s0)
Any command-line input or output is written as follows:
C:\Pythonbook\PyQt5>pyuic5 demoLineEdit.ui -o demoLineEdit.py
Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "The amount the slider handle moves can be specified via the pageStep property."
Warnings or important notes appear like this.
Tips and tricks appear like this.
