Как обратиться к числу написанному внутри LineEdit?

Question

Я работаю в Pyside Мне нужно чтобы я смог как либо обратиться к числу или тексту написанному внутри программного окошка в LineEdit, допустим мне хочется чтобы после нажатия кнопки к тому числу которое я написал прибавилась двойка. как мне это сделать? Код:

#
app = QtGui.QApplication(sys.argv)
#
Dialog = QtGui.QDialog()
ui = Ui_Dialog()
ui.setupUi(Dialog)
Dialog.show()
#Действие

#
sys.exit(app.exec_())

Нужно написать логический код в: #Действие

Answer 1

мне хочется чтобы после нажатия кнопки к тому числу которое я написал прибавилась двойка

Для этого нужно повесить сигнал кнопки clicked на метод, а в методе обратиться к текущему тексту lineEdit и поменять его:

self.ui.pushButton.clicked.connect(self._on_push_button_click)
...

    def _on_push_button_click(self):
        value = self.ui.lineEdit.text()
        self.ui.lineEdit.setText(value + "2")

Сделал отдельный класс, в которым добавил элементы из Ui_Dialog. Советую и вам так дальше делать, т.к. лучше разделять графический интерфейс и логику под сущностям.

Пример:

from PySide import QtCore, QtGui
import sys

class Ui_Dialog(object):
    def setupUi(self, Dialog):
        Dialog.setObjectName("Dialog")
        Dialog.resize(400, 391)
        Dialog.setCursor(QtCore.Qt.ArrowCursor)
        Dialog.setStyleSheet("QDialog{\n"
"background:#434542;\n"
"}")
        self.pushButton = QtGui.QPushButton(Dialog)
        self.pushButton.setGeometry(QtCore.QRect(330, 20, 51, 51))
        font = QtGui.QFont()
        font.setFamily("Century Gothic")
        font.setPointSize(16)
        font.setWeight(75)
        font.setBold(True)
        self.pushButton.setFont(font)
        self.pushButton.setCursor(QtCore.Qt.ArrowCursor)
        self.pushButton.setStyleSheet("QPushButton {\n"
"background: #282928;\n"
" border: 3px solid #FFFFFF;\n"
" border-radius: 10px;\n"
"border-color: #7ad442;\n"
"color:#ffffff;\n"
"\n"
"}\n"
"")

        self.textBrowser = QtGui.QTextBrowser(Dialog)
        self.textBrowser.setGeometry(QtCore.QRect(20, 190, 281, 131))

        font.setFamily("Century Gothic")
        self.textBrowser.setFont(font)
        self.textBrowser.setStyleSheet("QTextBrowser {\n"
"background: #434542;\n"
"border: 3px solid #7ad442;\n"
"\n"
"}")
        self.textBrowser.setObjectName("textBrowser")
        self.label_2 = QtGui.QLabel(Dialog)
        self.label_2.setGeometry(QtCore.QRect(10, 340, 281, 41))
        font = QtGui.QFont()
        font.setFamily("Univers Condensed")
        font.setPointSize(11)
        font.setWeight(75)
        font.setBold(True)
        self.label_2.setFont(font)
        self.label_2.setStyleSheet("QLabel {\n"

if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)

    mw = MainWindow()
    mw.show()

    sys.exit(app.exec_())

PS.

Советую давать виджетам на форме в objectName свои названия, чтобы при генерации кода по форме, они получали понятные названия.

Например, для кнопки pushButton с objectName=pushButton можно было дать, например, такое название objectName = pb_ok, тогда в коде будет понятнее для чего этот виджет

Answer 2

Рекомендую повысить версию до PySide2 или PyQt5 и можно попробовать:

'''
import PySide
import self as self
from PySide import QtCore, QtGui
'''
import sys
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.Qt import *
