Я пытаюсь изменить размер виджета таблицы внутри QVBoxlayout, который я добавляю в виде строки в QFormlayout в pyqt
В настоящее время я добавляю QVboxlayout, который содержит внутри себя виджет таблицы в виде строки в Qformlayout.
И главная цель - разместить виджет Таблица до конца окна приложения, чтобы он получил оставшееся пространство в окне
Используя приведенный ниже код -
class PGSearchDetails():
def __init__(self,parent=None):
self.widget_pgsd = QWidget()
self.layout_pgsd = QFormLayout()
self.layout_pgsd.setFieldGrowthPolicy(QFormLayout.FieldGrowthPolicy(2|1))
self.PG_Id = QLineEdit()
#rx = QRegExp("^\\D+[!,@,#,$,%,\^,&,*,(,),:,\",{,},?,<,>,|,+,-,~,]")
#rx = QRegExp(" (?!(@,#,$|%|\^|&|*|(|)|:|\"|{|}|?|<|>|\||+|-|~|!))[\\w]+")
str_rx = QRegExp("^[A-Za-z*]{20}(?!@#$%^&*():\"\{\}?<>\|+-~!_-)")
adhr_rx = QRegExp("[A-Z0-9]{12}(?!@#$%^&*():\"\{\}?<>\|+-~!_)")
val = QRegExpValidator(str_rx)
val3 = QRegExpValidator(adhr_rx)
self.PG_Id.setValidator(val3)
self.LastName = QLineEdit()
self.LastName.setValidator(val)
self.MobNum = QLineEdit()
qint_val = QIntValidator()
qint_val.setTop(10)
self.MobNum.setValidator(qint_val)
self.layout_pgsd.addRow("First Name",self.PG_Id)
self.layout_pgsd.addRow("Last Name",self.LastName)
self.layout_pgsd.addRow("Mobile Number",self.MobNum)
update_layout_pgsd = QHBoxLayout()
layout_test,table = dbv.Search_View(self.getT)
#layout_test.setGeometry(QRect(200,200,50,50))
#table.setMaximumHeight(800)
#table.setGeometry(200,200,200,200)
#table.setGeometry(1,1,1000,600)
table.resize(1000,600)
update_btn_pgsd = QPushButton('Update')
reset_btn_pgsd = QPushButton('Reset')
update_layout_pgsd.addWidget(update_btn_pgsd)
update_layout_pgsd.addWidget(reset_btn_pgsd)
self.layout_pgsd.addRow(update_layout_pgsd)
##Adding the Table Widget to FormLayot
self.layout_pgsd.addRow(layout_test)
update_btn_pgsd.clicked.connect(partial(self.database,table,self.MobNum,
self.LastName))
#self.widget.setLayout(self.layout_pgsd)
def returnLayout(self):
return self.layout_pgsd
def returnWidget(self):
return self.widget_pgsd
def getT(self,linedit):
print("LE--->",linedit.text())
Настройка QtableWidget ---
def Search_View(self):
print("Inside Search_view")
central_widget = QWidget() # Create a central widget
db_layout = QVBoxLayout()
#col_count = len(self.pg_details.__dict__.keys())
col_count = 3
table = QTableWidget() # Create a table
#central_widget.setGeometry(200,200,150,150)
#table.maximumSize()
#db_layout.setMaximumSize(200)
db_layout.setGeometry(QRect(0,0,100,30))
db_layout.addWidget(table)
##Tried resizing the Table widget but nothing seems to works
table.resize(1000,600)
table.setGeometry(0,2,1000,600)
#central_widget.resize(central_widget.sizeHint())
#central_widget.setColumnWidth(1000,600)
#db_layout.addItem(update_layout)
central_widget.setLayout(db_layout)
print("Geometry H--->",table.geometry().height())
print("Geometry W--->",table.geometry().width())
print("Geometry X--->",table.geometry().x())
print("Geometry Y--->",table.geometry().y())
return central_widget,table
После функции изменения размера геометрия таблицы изменяется на 1000 600, но на экране она не отображается. На экране приложения он остается одинаковым каждый раз

Кажется, я не понимаю, чего мне здесь не хватает
