In this recipe, we'll demonstrate one of the simplest methods used for accepting input from a user, a text input dialog.
Open the QGIS Python Console by selecting the Plugins menu and then clicking on Python Console.
In this recipe, we will initialize the dialog and then configure its title and label. We'll set the editing mode and the default text. When you click on the OK button, the text will be printed to the Python Console. To do this, we need to perform the following steps:
from PyQt4.QtGui import *
qid = QInputDialog()
title = "Enter Your Name" label = "Name: " mode = QLineEdit.Normal default = "<your name here>"
text, ok = QInputDialog.getText(qid, title, label, mode, default)
print text
