It generates this (Ubuntu 18.04):
I want to use mousewheel only on the left QScrollArea, for which I've made a separate class. However, its wheelEvent fires only when I'm outside the red box, not when I hover over it. How can I make ScrollAreaWheel.wheelEvent fire even when mouse is over the child label (the red box)?
You are the QLabel placing on top of the QScrollArea instead of placing it inside, visually it is the same but at the level of events it is not.

Here the GUI with the table not correctly sized:
Thank you in advance for your support!
First you must correctly state the layouts and you should not use setGeometry since that is the task of the layouts. I have modified the structure of your code to have an order so at the end I point out the relationship between the layouts.

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():

self.layout_pgsd.setFieldGrowthPolicy(QFormLayout.FieldGrowthPolicy(2|1))

adhr_rx = QRegExp("[A-Z0-9]{12}(?!##$%^&*():\"\{\}?<>\|+-~!_)")
val = QRegExpValidator(str_rx)

self.PG_Id.setValidator(val3)

#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())

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

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.groupscrolllayouttest.addWidget(self.groupscrollbartest)
self.groupscrolllayouttest.addWidget(scroll)
self.tab_ModelSelect.setLayout(self.groupscrolllayouttest)
def main():
app = QApplication(sys.argv)
ex = SurfViewer(app)
ex.setWindowTitle('window')
# ex.showMaximized()
ex.show()
sys.exit(app.exec_( ))
if __name__ == '__main__':
main()
and here is the result:
In my more complex code I used QTabWidget, that why I included it in this example. What I would like to do is having a horizontal scrollbar to the bottom which allows me to shift the text left and right. Obviously I want keep the other one to shift the text up and down.
I also try to add a second scroll bar to the first one (groupscrolllayouttest)
from PyQt5.QtGui import *
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *
import sys
class SurfViewer(QMainWindow):
def __init__(self, parent=None):
super(SurfViewer, self).__init__()
self.parent = parent
self.centralTabs= QTabWidget()
self.setCentralWidget(self.centralTabs)
self.setFixedWidth(200)
self.setFixedHeight(200)
#tab Model selection
self.tab_ModelSelect = QWidget()
self.centralTabs.addTab(self.tab_ModelSelect,"Label")
self.groupscrolllayouttest2 = QVBoxLayout() ####
self.groupscrollbartest2 = QGroupBox() ####
self.groupscrolllayouttest = QHBoxLayout() ####
self.groupscrollbartest = QGroupBox() ####
self.mainHBOX_param_scene = QVBoxLayout()
for i in range(10):
Label = QLabel('BlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBlaBla')
Label.setFixedWidth(200)
self.mainHBOX_param_scene.addWidget(Label)
#
scroll = QScrollArea()
scroll.setWidget(self.groupscrollbartest)
scroll.setWidgetResizable(True)
scroll.setFixedWidth(20)
scroll.setVerticalScrollBarPolicy(Qt.ScrollBarAsNeeded)
scroll.setHorizontalScrollBarPolicy(Qt.ScrollBarAsNeeded)
# self.mainHBOX_param_scene.addWidget(scroll)
self.groupscrollbartest.setLayout(self.mainHBOX_param_scene)
self.groupscrolllayouttest.addWidget(self.groupscrollbartest)
self.groupscrolllayouttest.addWidget(scroll)
scroll2 = QScrollArea()
scroll2.setWidget(self.groupscrollbartest2)
scroll2.setWidgetResizable(True)
scroll2.setFixedWidth(20)
scroll2.setVerticalScrollBarPolicy(Qt.ScrollBarAsNeeded)
scroll2.setHorizontalScrollBarPolicy(Qt.ScrollBarAsNeeded)
self.groupscrollbartest2.setLayout(self.groupscrolllayouttest)
self.groupscrolllayouttest2.addWidget(self.groupscrollbartest2)
self.groupscrolllayouttest2.addWidget(scroll2)
self.tab_ModelSelect.setLayout(self.groupscrolllayouttest2)
def main():
app = QApplication(sys.argv)
ex = SurfViewer(app)
ex.setWindowTitle('window')
# ex.showMaximized()
ex.show()
sys.exit(app.exec_( ))
if __name__ == '__main__':
main()
But I end up with a strange scroll bar:
So now I'm stuck. Any idea?
What you have to do is create a widget, and in that widget place the QGroupBox:
[...]
scroll = QScrollArea()
widget = QWidget(self)
widget.setLayout(QVBoxLayout())
widget.layout().addWidget(self.groupscrollbartest)
scroll.setWidget(widget)
scroll.setWidgetResizable(True)
self.groupscrollbartest.setLayout(self.mainHBOX_param_scene)
self.groupscrolllayouttest.addWidget(scroll)
self.tab_ModelSelect.setLayout(self.groupscrolllayouttest)
[...]
Output:
I am trying to create a dialog with three tabs using PyQt. However, I am annoyed because although the dialog is displayed, the embedded widgets are not displayed!. I suppose this is a very simple problem with a correspondingly very simple solution, but I am struck! Can anyone give a hint? Thanks in advance!
Here is my code so far:
import sys
from PyQt4.QtCore import *
from PyQt4.QtGui import *
class TabbedDialog(QDialog):
def __init__(self, parent = None):
super(TabbedDialog, self).__init__(parent)
self.tabWidget = QTabWidget()
self.tabWidget.tab1 = QWidget()
self.tabWidget.tab2 = QWidget()
self.tabWidget.tab3 = QWidget()
self.tabWidget.addTab(self.tabWidget.tab1,"Tab 1")
self.tabWidget.addTab(self.tabWidget.tab2,"Tab 2")
self.tabWidget.addTab(self.tabWidget.tab3,"Tab 3")
self.tab1UI()
self.tab2UI()
self.tab3UI()
self.setWindowTitle("tab demo")
def tab1UI(self):
layout = QFormLayout()
layout.addRow("Name",QLineEdit())
layout.addRow("Address",QLineEdit())
self.tabWidget.setTabText(0,"Contact Details")
self.tabWidget.tab1.setLayout(layout)
def tab2UI(self):
layout = QFormLayout()
sex = QHBoxLayout()
sex.addWidget(QRadioButton("Male"))
sex.addWidget(QRadioButton("Female"))
layout.addRow(QLabel("Sex"),sex)
layout.addRow("Date of Birth",QLineEdit())
self.tabWidget.setTabText(1,"Personal Details")
self.tabWidget.tab2.setLayout(layout)
def tab3UI(self):
layout = QHBoxLayout()
layout.addWidget(QLabel("subjects"))
layout.addWidget(QCheckBox("Physics"))
layout.addWidget(QCheckBox("Maths"))
self.tabWidget.setTabText(2,"Education Details")
self.tabWidget.tab3.setLayout(layout)
if __name__ == '__main__':
app = QApplication(sys.argv)
form = TabbedDialog()
retval = form.exec_()
here is my solution to the problem
On the init method, I declared a layout, then added the 'tabWidget' widget to that layout and set that layout as the layout of your QDialog.
def __init__(self, parent = None):
super(TabbedDialog, self).__init__(parent)
self.tabWidget = QTabWidget()
self.tabWidget.tab1 = QWidget()
self.tabWidget.tab2 = QWidget()
self.tabWidget.tab3 = QWidget()
self.tabWidget.addTab(self.tabWidget.tab1,"Tab 1")
self.tabWidget.addTab(self.tabWidget.tab2,"Tab 2")
self.tabWidget.addTab(self.tabWidget.tab3,"Tab 3")
self.tab1UI()
self.tab2UI()
self.tab3UI()
self.setWindowTitle("tab demo")
# Here is the addition to the code.
mainLayout = QVBoxLayout()
mainLayout.addWidget(self.tabWidget)
self.setLayout(mainLayout)
