QinputDialogشرح ال

 QinputDialog

 

Ok, cancelبالإضافة إلي زرارين QLabel,QSpinBox, QTextBox,QComboBoxهو عبارة عن نافذة صغيرة بها 

 

Create object of QFileDialog: 

 

Return_Value,ok=QInputDialog().getreturn_type(self,’title’,’label_text’)

getreturn_type:getInt(),getText(),getItem(),getDouble()

 

 

getInt()	لإستقبال الأرقام الصحيحةQSpinBox تعمل
getDouble()	لإستقبال الأرقام العشريةQSpinBox تعمل
getText()	لإستقبال النصوصQLineEdit تعمل
getItem()	لإختيار القيم من خلالهQComboBoxتعملَ

 

Functions:

 

نستخدم الواجهة التالية:QLineEditلإستقبال نص من

text, ok = QInputDialog().getText(self, "QInputDialog().getText()",                                   "User name:", QLineEdit.Normal,                                   QDir().home().dirName()) if ok and text:     print(text)

 

نستخدم الواجهة التالية:QComboBoxللإختيار قيمة من

items = ["Spring", "Summer", "Fall", "Winter"] item, ok = QInputDialog().getItem(self, "QInputDialog().getItem()",                                   "Season:", items, 0, False) if ok:     print(item)

 

نستخدم الواجهة التالية: QSpinBoxللإستقبال رقم صحيح من

def getint(self):     num, ok = QInputDialog.getInt(self, "integer input dualog", "enter a number",int default_value)     if ok:         self.le2.setText(str(num))

 

نستخدم الواجهة التالية: QSpinBoxللإستقبال رقم عشري من

def getint(self):     num, ok = QInputDialog.getInt(self, "integer input dualog", "enter a number")     if ok:         self.le2.setText(str(num))
