Unable to resize QTableWidget
I m trying to resize a table widget inside a QVBoxlayout which I further add as a row to a QFormlayout in pyqt
I m currently adding a QVboxlayout which contains a table widget inside it as a row in a Qformlayout.
And the main aim is to strecth the Table widget till the end of the application window that it acquires the left over space on the window
Using the below code -
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())
QtableWidget setup ---
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
After the resize function, The table geometry changes to 1000,600 but on the screen it is not reflected. On the app screen it remains the same size everytime
Also find the entire code which contains the Tablayouts as well and Stacked widget for individual radio buttons
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.init_ui()
def init_ui(self):
self.tab_widget = MainTabWindow()
self.setCentralWidget(self.tab_widget)
self.show()
class MainTabWindow(QTabWidget):
def __init__(self,parent=None):
super(MainTabWindow, self).__init__(parent)
self.init_ui()
def init_ui(self):
self.setWindowTitle('PyQt5 Tab Example')
self.tab1 = QWidget()
self.addTab(self.tab1,"Search")
self.PGSearchTab()
def PGSearchTab(self):
print("Search Tab First Tab")
self.central_layout = QVBoxLayout()
self.stack1 = QWidget()
self.stack2 = QWidget()
self.stack3 = QWidget()
self.stack_widget = QStackedWidget()
button_layout = QHBoxLayout()
radio_button_1 = QRadioButton("Search")
radio_button_2 = QRadioButton("Add")
radio_button_3 = QRadioButton("Update")
button_layout.addWidget(radio_button_1)
button_layout.addWidget(radio_button_2)
button_layout.addWidget(radio_button_3)
self.central_layout.addItem(button_layout)
self.stack_widget.addWidget(self.stack1)
self.stack_widget.addWidget(self.stack2)
self.stack_widget.addWidget(self.stack3)
self.central_layout.addWidget(self.stack_widget)
radio_button_1.toggled.connect(lambda :self.SelectButtonCheck(radio_button_1))
self.setTabText(0,"Search")
update_layout = QHBoxLayout()
update_layout.setAlignment(QtCore.Qt.AlignBottom)
update_btn = QPushButton('Update')
reset_btn = QPushButton('Reset')
update_layout.addWidget(update_btn)
update_layout.addWidget(reset_btn)
self.tab1.setLayout(self.central_layout)
def SelectButtonCheck(self,b):
if b.text() == "Search":
if b.isChecked():
print(b.text()+ "is selected")
self.obj_pgsd = pgsd.PGSearchDetails()
layout = self.obj_pgsd.returnLayout()
if self.stack1.layout() is None:
self.stack1.setLayout(layout)
self.stack_widget.setCurrentIndex(0)
def main():
application = QApplication(sys.argv)
main_window = MainTabWindow()
main_window.show()
sys.exit(application.exec_())
if __name__ == '__main__':
main()
I do not seem to understand what is I m missing here
Any pointers would be appreciated.
Also find the working code to execute the above layout setup.

The problem is that QFormLayout makes every time you add a widget using addRow () uses strech, the solution is to use a QVBoxLayout, and in that QVBoxLayout is to pass the QFormLayout and the layout_test.
class PGSearchDetails():
def __init__(self,parent=None):
self.widget_pgsd = QWidget()
self.layout = QVBoxLayout() # <---
self.layout_pgsd = QFormLayout()
self.layout.addLayout(self.layout_pgsd) # <---
self.layout_pgsd.setFieldGrowthPolicy(QFormLayout.FieldGrowthPolicy(2|1))
...
self.layout_pgsd.addRow(update_layout_pgsd)
##Adding the Table Widget to FormLayot
# self.layout_pgsd.addRow(layout_test)
self.layout.addWidget(layout_test) # <---
update_btn_pgsd.clicked.connect(partial(self.database,table,self.MobNum,
self.LastName))
def returnLayout(self):
return self.layout # <---
