Access to Widget which is added to layout in other file - python

I'm trying to access a widget that is added to the layout in which it is displayed from another file.
ui_main.py
from ui_main_pages import Ui_MainPages
class UI_MainWindow(object):
def setup_ui(self, parent):
self.central_widget = QWidget()
self.central_widget_layout = QVBoxLayout(self.central_widget)
self.window = CustomWindow()
self.central_widget_layout.addWidget(self.window)
# Add Left, Right, Title frames code ...
self.content_area_frame = QFrame()
self.content_area_layout = QHBoxLayout(self.content_area_frame)
# Import pages from stacked widget
self.load_pages = Ui_MainPages()
self.load_pages.setupUi(self.content_area_left_frame)
ui_main_pages.py
class Ui_MainPages(object):
def setupUi(self, MainPages):
self.main_pages_layout = QVBoxLayout(MainPages)
self.pages = QStackedWidget(MainPages)
self.page_1 = QWidget()
# add page 1 code
self.page_2 = QWidget()
self.page_2_layout = QVBoxLayout(self.page_2)
self.scroll_area = QScrollArea(self.page_2)
self.contents = QWidget()
self.verticalLayout = QVBoxLayout(self.contents)
self.title_label = QLabel(self.contents)
self.verticalLayout.addWidget(self.title_label)
self.description_label = QLabel(self.contents)
self.verticalLayout.addWidget(self.description_label)
self.row_1_layout = QHBoxLayout()
self.row_1_layout.setObjectName(u"row_1_layout")
self.verticalLayout.addLayout(self.row_1_layout)
self.row_2_layout = QHBoxLayout()
self.row_2_layout.setObjectName(u"row_2_layout")
self.verticalLayout.addLayout(self.row_2_layout)
self.row_3_layout = QHBoxLayout()
self.row_3_layout.setObjectName(u"row_3_layout")
self.verticalLayout.addLayout(self.row_3_layout)
self.row_4_layout = QVBoxLayout()
self.row_4_layout.setObjectName(u"row_4_layout")
self.verticalLayout.addLayout(self.row_4_layout)
self.row_5_layout = QVBoxLayout()
self.row_5_layout.setObjectName(u"row_5_layout")
self.verticalLayout.addLayout(self.row_5_layout)
self.scroll_area.setWidget(self.contents)
self.page_2_layout.addWidget(self.scroll_area)
self.pages.addWidget(self.page_2)
Where i add the table widget is in the page_2 to row_5_layout, lets see in the next code
setup_main_window.py
from ui_main import UI_MainWindow
class SetupMainWindow:
def __init__(self):
super().__init__()
# SETUP MAIN WINDOw
# Load widgets from "gui\uis\main_window\ui_main.py"
# ///////////////////////////////////////////////////////////////
self.ui = UI_MainWindow()
self.ui.setup_ui(self)
def setup_gui(self):
# OBJECTS FOR LOAD PAGES
# PAGE 1 - ADD LOGO TO MAIN PAGE
self.logo_svg = QSvgWidget(Functions.set_svg_image("logo_home.svg"))
self.ui.load_pages.logo_layout.addWidget(self.logo_svg, Qt.AlignCenter, Qt.AlignCenter)
# PAGE 2
# TABLE WIDGETS
self.table_widget = PyTableWidget()
self.ui.load_pages.row_5_layout.addWidget(self.table_widget)
In the above file I add the table widget to the layout in ui_main_pages, and in the next file I try load a html file a make a pandas dataframe, then set a custom model to table_widget
app_file.py
from ui_main import UI_MainWindow
class Files:
def __init__(self):
super().__init__()
# IMPORT WIDGETS
self.ui = UI_MainWindow()
self.ui.setup_ui()
def load(self):
global file_name
# FILE DIALOG
dlg_file = QFileDialog.getOpenFileName(parent=self, caption=self.tr("Select a file"),filter=self.tr('HTML Files (*.html)'),)
# READ FILE
if dlg_file:
self.df_squad = FMi.setting_up_pandas(dlg_file[0])
# FMi is a custom package, which read the file and convert it to a dataframe
# self.df_squad is the dataframe
# Below i try to select the table_widget created before and edit it
self.ui.load_pages.row_5_layout.table_widget.setSelectionBehavior(QTableView.SelectRows)
model = CustomPandasModel(self.df_squad)
self.ui.load_pages.row_5_layout.table_widget.setModel(model)
I have already connected a button to load function in Files class, and it works up to the line of "setSelectionBehavior".
The error is:
AttributeError: 'PySide6.QtWidgets.QVBoxLayout' object has no attribute 'table_widget'
EDIT
The last file main.py from where I run all the project
from ui_main import UI_MainWindow
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.ui = UI_MainWindow()
self.ui.setup_ui(self)

Clicking on a QGroupBox programmatically

This is a follow-up to this question of mine: Make QGroupBox selectable and clickable
My related question is how can I programmatically click on the first group upon startup?
I have tried to do this after implementing the solution provided in the original question using:
scrollLayout.itemAt(0).widget().click()
However, this did not work.
What am I missing?
Try it:
from PyQt5 import QtWidgets, QtGui, QtCore
class GroupBox(QtWidgets.QGroupBox):
clicked = QtCore.pyqtSignal(str, object)
def __init__(self, title):
super(GroupBox, self).__init__()
self.title = title
self.setTitle(self.title)
def mousePressEvent(self, event):
child = self.childAt(event.pos())
if not child:
child = self
self.clicked.emit(self.title, child)
class MainWindow(QtWidgets.QMainWindow):
def __init__(self):
super(MainWindow, self).__init__()
w = QtWidgets.QWidget()
layout = QtWidgets.QVBoxLayout()
w.setLayout(layout)
self.setCentralWidget(w)
my_tree = QtWidgets.QTreeWidget()
layout.addWidget(my_tree)
alpha = QtWidgets.QTreeWidgetItem(my_tree, ['Alpha'])
beta = QtWidgets.QTreeWidgetItem(my_tree, ['Beta'])
alpha.addChild(QtWidgets.QTreeWidgetItem(['one']))
alpha.addChild(QtWidgets.QTreeWidgetItem(['two']))
beta.addChild(QtWidgets.QTreeWidgetItem(['first']))
beta.addChild(QtWidgets.QTreeWidgetItem(['second']))
my_tree.expandAll()
alpha.child(0).setSelected(True)
scroll = QtWidgets.QScrollArea()
layout.addWidget(scroll)
scrollLayout = QtWidgets.QVBoxLayout()
scrollW = QtWidgets.QWidget()
scroll.setWidget(scrollW)
scrollW.setLayout(scrollLayout)
scrollLayout.setAlignment(QtCore.Qt.AlignTop)
scroll.setVerticalScrollBarPolicy(QtCore.Qt.ScrollBarAlwaysOn)
scroll.setHorizontalScrollBarPolicy(QtCore.Qt.ScrollBarAlwaysOff)
scroll.setWidgetResizable(True)
for _ in range(5):
fooGroup = GroupBox(f'GroupBox_{_}')
fooGroup.setObjectName(f'fooGroup {_}')
fooGroup.clicked.connect(self.onFooGroupClick)
fooLayout = QtWidgets.QVBoxLayout()
fooGroup.setLayout(fooLayout)
fooItem1 = QtWidgets.QLabel("fooItem1", objectName="fooItem1")
fooItem1.setStyleSheet('background: #44ffff')
fooItem2 = QtWidgets.QLabel("fooItem2", objectName="fooItem2")
fooItem2.setStyleSheet('background: #ffff56;')
fooItem3 = QtWidgets.QLabel("fooItem3", objectName="fooItem3")
fooItem3.setStyleSheet('background: #ff42ff;')
fooLayout.addWidget(fooItem1)
fooLayout.addWidget(fooItem2)
fooLayout.addWidget(fooItem3)
scrollLayout.addWidget(fooGroup)
# scrollLayout.itemAt(0).widget().click() # ---
_fooGroup = scrollLayout.itemAt(0).widget() # +++
_fooGroup.clicked.emit('GroupBox_0', _fooGroup) # +++
def onFooGroupClick(self, title, obj):
print(f"Group: {title}; objectName=`{obj.objectName()}`")

window.show()

Add/Remove layout containing multiple widgets pyqt

I'm trying to make a gui that allows the addition/removal of multiple QtWidgets. The user selects a file and has the option off adding a comment in the lineedit next to it. A quick search on this site has so far given me the following code which allows me to add rows widgets.
import os
import sys
from PyQt5 import QtGui, QtCore, QtWidgets
class Additional(QtWidgets.QMainWindow):
def __init__(self):
super(Additional, self).__init__()
self.addButton = QtWidgets.QPushButton(' + ')
self.delButton = QtWidgets.QPushButton(' - ')
self.acceptButton = QtWidgets.QPushButton('Accept')
self.cancelButton = QtWidgets.QPushButton('Cancel')
self.addButton.clicked.connect(self.addWidget)
self.delButton.clicked.connect(self.delWidget)
self.acceptButton.clicked.connect(self.acceptValues)
self.cancelButton.clicked.connect(self.cancel)
self.scrollLayout = QtWidgets.QFormLayout()
self.scrollWidget = QtWidgets.QWidget()
self.scrollWidget.setLayout(self.scrollLayout)
self.scrollArea = QtWidgets.QScrollArea()
self.scrollArea.setWidgetResizable(True)
self.scrollArea.setWidget(self.scrollWidget)
self.button_layout = QtWidgets.QVBoxLayout()
self.mainLayout = QtWidgets.QHBoxLayout()
self.button_layout.addWidget(self.addButton)
self.button_layout.addWidget(self.delButton)
self.button_layout.addWidget(self.acceptButton)
self.button_layout.addWidget(self.cancelButton)
self.mainLayout.addLayout(self.button_layout)
self.mainLayout.addWidget(self.scrollArea)
self.centralWidget = QtWidgets.QWidget()
self.centralWidget.setLayout(self.mainLayout)
self.setCentralWidget(self.centralWidget)
self.resize(800, 200)
self.setFixedSize(self.size())
self.show()
def addWidget(self):
self.scrollLayout.addRow(AddRow())
def delWidget(self):
# Would this call another class to remove the row? If so, how?
pass
def acceptValues(self):
# Would I count the widgets in the 'scroll' area and get the data from that?
pass
def cancel(self):
QtCore.QCoreApplication.instance().quit()
# BTW, is this the right way to close the window/instance?
class AddRow(QtWidgets.QWidget):
def __init__( self, parent=None):
super(AddRow, self).__init__(parent)
self.button = QtWidgets.QPushButton('Select file')
self.label = QtWidgets.QLabel('Selection will go here')
self.lineedit = QtWidgets.QLineEdit()
self.lineedit.setPlaceholderText("Rename (optional)...")
# Would I add the button callback here?
layout = QtWidgets.QHBoxLayout()
layout.addWidget(self.button)
layout.addWidget(self.label)
layout.addWidget(self.lineedit)
self.setLayout(layout)
app = QtWidgets.QApplication(sys.argv)
myApp = Additional()
app.exec_()
I'm trying to figure out:
How to delete the last row that's been added.
How to assign the action to the button (this be done in the 'AddRow'
class likeself.buttton.clicked.callback(self.selectfile)
How to collect the data from the rows (ie, after 'accept' has been
clicked)
Any ideas would be welcome!
Before pointing to the solution, I'm just going to change the name of the AddRow class to RowWidget because a class should not indicate action.
class RowWidget(QtWidgets.QWidget):
def __init__( self, parent=None):
super(RowWidget, self).__init__(parent)
...
How to delete the last row that's been added ?
Since you are using QFormLayout and assuming that you are using a version PyQt5>=5.8 you can use the removeRow() method:
#QtCore.pyqtSlot()
def delWidget(self):
if self.scrollLayout.rowCount() > 0:
self.scrollLayout.removeRow(self.scrollLayout.rowCount()-1)
How to assign the action to the button (this be done in the 'AddRow' class likeself.buttton.clicked.callback(self.selectfile)?
Each part of your application must be independent so the slot that you select the file must be part only of RowWidget, and RowWidget must have a method that returns that value:
class RowWidget(QtWidgets.QWidget):
def __init__( self, parent=None):
super(RowWidget, self).__init__(parent)
self.button = QtWidgets.QPushButton('Select file')
self.label = QtWidgets.QLabel('Selection will go here')
self.lineedit = QtWidgets.QLineEdit()
self.lineedit.setPlaceholderText("Rename (optional)...")
self.button.clicked.connect(self.on_select_file)
layout = QtWidgets.QHBoxLayout(self)
layout.addWidget(self.button)
layout.addWidget(self.label)
layout.addWidget(self.lineedit)
#QtCore.pyqtSlot()
def on_select_file(self):
filename, _ = QtWidgets.QFileDialog.getOpenFileName(self, "Open File")
if filename:
self.lineedit.setText(filename)
def get_filename(self):
return self.lineedit.text()
How to collect the data from the rows (ie, after 'accept' has been clicked)?
The widgets attached to a layout are children of the widget where the layout has been added, that widget can be obtained through parentWidget(), having that parent we can obtain their children through findChildren():
#QtCore.pyqtSlot()
def acceptValues(self):
l_values = []
for w in self.scrollLayout.parentWidget().findChildren(RowWidget):
l_values.append(w.get_filename())
print(l_values)
The previous method may fail if the parentWidget() has other children that belong to RowWidget.
Another option, and that does not fail is to iterate through the QLayoutItems:
#QtCore.pyqtSlot()
def acceptValues(self):
l_values = []
for i in range(self.scrollLayout.rowCount()):
layout_item = self.scrollLayout.itemAt(i)
if isinstance(layout_item.widget(), RowWidget):
l_values.append(layout_item.widget().get_filename())
print(l_values)

PYQT - Qframe - Show/Hide without shifting the rest of the window

I got the following Test-GUI.
There is a left layout and a right layout where i want to put buttons and other things onto. The button on the right should make a QFrame unhide or hide and all the widgets in it. This works.
But after the first two clicks, the layout is different.
The TableWidget on the left layout gets resized and the button is a bit more south.
Is there an easy way to fix this?

PyQt QVBoxLayout and missing widgets?

I am trying to set up a window that has a text input & a combo box. At the moment I just want to see the text & the selection displayed under the appropriate widget.
I have used QVBoxLayout() as I will be adding more stuff later & thought it would be a simple way of laying out the window.
Unfortunately only the combo box ever gets displayed. The code:
from PyQt4 import QtCore, QtGui
import sys
class Polyhedra(QtGui.QMainWindow):
def __init__(self):
super(Polyhedra, self).__init__()
self.initUI()
def initUI(self):
# Poly names
self.pNames = QtGui.QLabel(self)
polyNameInput = QtGui.QLineEdit(self)
# polyName entry
polyNameInput.textChanged[str].connect(self.onChanged)
# Polytype selection
self.defaultPolyType = QtGui.QLabel("Random polyhedra", self)
polyType = QtGui.QComboBox(self)
polyType.addItem("Random polyhedra")
polyType.addItem("Spheres")
polyType.addItem("Waterman polyhedra")
polyType.activated[str].connect(self.onActivated)
# Layout
vbox = QtGui.QVBoxLayout()
vbox.addWidget(polyNameInput)
vbox.addWidget(self.pNames)
vbox.addWidget(polyType)
vbox.addWidget(self.defaultPolyType)
vbox.addStretch()
# Set up window
self.setGeometry(500, 500, 300, 300)
self.setWindowTitle('Pyticle')
self.show()
# Combo box
def onActivated(self, text):
self.defaultPolyType.setText(text)
self.defaultPolyType.adjustSize()
# Poly names
def onChanged(self, text):
self.pNames.setText(text)
self.pNames.adjustSize()
def main():
app = QtGui.QApplication(sys.argv)
ex = Polyhedra()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
So whats going on here? Am I missing some important directive to QVBoxLayout()?
Using Python 2.7 on Win 7 x64 machine with PyQt 4.
EDIT: Additional problem (still related to missing widgets)
I have amended the code following the clarification below. I then added more widgets when a certain option in the combobox is chosen (see below) but these widgets dont show. I attempted to add a child widget to 'widget' called 'ranPolyWidget' to take a numerical input.
# Combo box
def onActivated(self, text):
if text=="Random polyhedra":
self.randomSeedLbl = QtGui.QLabel("Seed: ", self)
randomSeed = QtGui.QLineEdit(self)
randomSeed.textChanged[str].connect(self.setSeed)
ranPolyWidget = QtGui.QWidget(self.widget)
rbox = QtGui.QVBoxLayout(ranPolyWidget)
rbox.addWidget(randomSeed)
self.layout().addWidget(ranPolyWidget)
self.show()
else:
self.defaultPolyType.setText(text)
self.defaultPolyType.adjustSize()
Same issue as before, no widgets. I am missing something pretty fundamental arent I?
You're forgetting to set it to the widget or main window, so since the QComboBox is the last one made, it's the only one displayed. Basically, everything is added to the layout, but the layout is "free-floating", and so it does not display properly. You need to bind the layout to a QWidget, which I do here. For most widgets, you can can do this by the QtGui.QVBoxLayout(widget) or by widget.setLayout(layout).
Alternatively, if you want multiple layouts on a widget, you can do have a parent layout and then add each child layout to the main layout.
EDIT: This is a better answer:
Make a widget, set layout to widget and set as central widget.
QMainWindow-s don't like you using the builtin layout or overriding it.
widget = QtGui.QWidget()
vbox = QtGui.QVBoxLayout(widget)
self.setCentralWidget(widget)
Old Answer:
self.layout().addLayout(vbox).
This should fix your issue:
Changes I made:
Since QMainWindow already has a layout, add in a widget (28G) and then set the VBoxLayout to the widget and add it to the main window.
from PyQt4 import QtCore, QtGui
import sys
class Polyhedra(QtGui.QMainWindow):
def __init__(self):
super(Polyhedra, self).__init__()
self.initUI()
def initUI(self):
# Poly names
self.pNames = QtGui.QLabel(self)
polyNameInput = QtGui.QLineEdit(self)
# polyName entry
polyNameInput.textChanged[str].connect(self.onChanged)
# Polytype selection
self.defaultPolyType = QtGui.QLabel("Random polyhedra", self)
polyType = QtGui.QComboBox(self)
polyType.addItem("Random polyhedra")
polyType.addItem("Spheres")
polyType.addItem("Waterman polyhedra")
polyType.activated[str].connect(self.onActivated)
# Layout
widget = QtGui.QWidget()
vbox = QtGui.QVBoxLayout(widget)
vbox.addWidget(polyNameInput)
vbox.addWidget(self.pNames)
vbox.addWidget(polyType)
vbox.addWidget(self.defaultPolyType)
vbox.addStretch()
# Set up window
self.setGeometry(500, 500, 300, 300)
self.setWindowTitle('Pyticle')
self.layout().addWidget(widget)
self.show()
# Combo box
def onActivated(self, text):
self.defaultPolyType.setText(text)
self.defaultPolyType.adjustSize()
# Poly names
def onChanged(self, text):
self.pNames.setText(text)
self.pNames.adjustSize()
def main():
app = QtGui.QApplication(sys.argv)
ex = Polyhedra()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
EDIT:
For adding new widgets, you should add them to the layout of the central widget and parent them to that widget.
Here's how I'd restructure your full code:
from PyQt4 import QtCore, QtGui
import sys
class CentralWidget(QtGui.QWidget):
def __init__(self, parent=None):
super(CentralWidget, self).__init__(parent)
# set layouts
self.layout = QtGui.QVBoxLayout(self)
# Poly names
self.pNames = QtGui.QLabel(self)
polyNameInput = QtGui.QLineEdit(self)
# polyName entry
polyNameInput.textChanged[str].connect(self.onChanged)
# Polytype selection
self.defaultPolyType = QtGui.QLabel("Random polyhedra", self)
polyType = QtGui.QComboBox(self)
polyType.addItem("Random polyhedra")
polyType.addItem("Spheres")
polyType.addItem("Waterman polyhedra")
polyType.activated[str].connect(self.onActivated)
self.layout.addWidget(polyNameInput)
self.layout.addWidget(self.pNames)
self.layout.addWidget(polyType)
self.layout.addWidget(self.defaultPolyType)
self.layout.addStretch()
def onActivated(self, text):
'''Adds randSeed to layout'''
if text=="Random polyhedra":
self.randomSeedLbl = QtGui.QLabel("Seed: ", self)
randomSeed = QtGui.QLineEdit(self)
randomSeed.textChanged[str].connect(self.setSeed)
self.layout.addWidget(randomSeed)
else:
self.defaultPolyType.setText(text)
self.defaultPolyType.adjustSize()
# Poly names
def onChanged(self, text):
self.pNames.setText(text)
self.pNames.adjustSize()
class Polyhedra(QtGui.QMainWindow):
def __init__(self):
super(Polyhedra, self).__init__()
# I like having class attributes bound in __init__
# Not very Qt of me, but it's more
# so I break everything down into subclasses
# find it more Pythonic and easier to debug: parent->child
# is easy when I need to repaint or delete child widgets
self.central_widget = CentralWidget(self)
self.setCentralWidget(self.central_widget)
# Set up window
self.setGeometry(500, 500, 300, 300)
self.setWindowTitle('Pyticle')
self.show()
# Combo box
def onActivated(self, text):
'''Pass to child'''
self.central_widget.onActivated(text)
def main():

How to fit widgets within frame in python

I am pretty new at python but currently I am getting some problem here with the part where I am unable to get my stuff fit within the width of the window.
I am trying to set it in such a way that it is:
Eg. Name Button
by the way, I am using Maya to integrate and run my stuff.
If I set it to central, it fits but it is all over the place as I only wanted it to occupy a portion only. So are there any ways for me to fit it nicely into it?
By the way, if its possible, can it be done using my current codings?
from PyQt4.QtCore import *
from PyQt4.QtGui import *
import sip
import maya.OpenMayaUI as mui
import os
class MainWindow(QMainWindow):
def __init__(self, parent = None):
QMainWindow.__init__(self,parent)
self.resize(400,800)
self.setWindowTitle("GetShots")
self.pubDock = SetShotInfo()
self.pubDW = QDockWidget(self.tr(""), self)
self.pubDW.setWidget(self.pubDock)
# self.setCentralWidget(self.pubDW)
def getMayaWindow():
ptr = mui.MQtUtil.mainWindow()
return sip.wrapinstance(long(ptr), QObject)
def main():
global app
global form
app = qApp
form = MainWindow(getMayaWindow())
form.show()
class GetShot(QFrame):
def __init__(self, parent = None, display=None):
QFrame.__init__(self, parent)
self.createWidgets()
self.createLayout()
def createWidgets(self):
self.showLabel = QLabel('Show')
self.showName = QLineEdit()
self.showName.setText(str(os.environ['SHOW']))
self.shotLabel = QLabel('Shot Filter')
self.shotName = QLineEdit()
self.showButton = QPushButton('Set Show')
self.showButton.setMaximumWidth(200)
self.shotButton = QPushButton('Filter Shots')
self.shotButton.setMaximumWidth(200)
self.rootLabel = QLabel('Change Root')
self.rootButton = QComboBox()
def createLayout(self):
# Sets the Layout of Show and Shot
setShowLayout = QHBoxLayout()
setShowLayout.addWidget(self.showLabel)
setShowLayout.addWidget(self.showName)
setShowLayout.addWidget(self.showButton)
setShotLayout = QHBoxLayout()
setShotLayout.addWidget(self.shotLabel)
setShotLayout.addWidget(self.shotName)
setShotLayout.addWidget(self.shotButton)
# Sets the Change Root Layout
chgRootLayout = QHBoxLayout()
chgRootLayout.addWidget(self.rootLabel)
chgRootLayout.addWidget(self.rootButton)
mainLayout = QVBoxLayout()
mainLayout.addLayout(setShowLayout)
mainLayout.addLayout(setShotLayout)
mainLayout.addLayout(chgRootLayout)
self.setLayout(mainLayout)
if __name__ == '__main__':
main()
You need to use Layouts, combine vertical and horizontal and play with the size policy of the widgets to fit them as you need.
Here's a quick example:
import sys
from PyQt4 import QtCore, QtGui
class ButtonContainer(QtGui.QWidget):
def __init__(self):
super(ButtonContainer, self).__init__()
self.initUI()
def initUI(self):
self.setGeometry( 150, 150, 650, 350)
btn = QtGui.QPushButton('Name button', self)
btn.setSizePolicy( QtGui.QSizePolicy( QtGui.QSizePolicy.Minimum, QtGui.QSizePolicy.Fixed ) )
vbox = QtGui.QVBoxLayout()
vbox.addWidget( btn )
self.setLayout(vbox)
self.show()
app = QtGui.QApplication(sys.argv)
ex = ButtonContainer()
sys.exit(app.exec_())
The commenters are right in suggesting QtDesigner, if you'd rather code it yourself at least have a mock up ui file where you can play interactively with the layouts and size policies, it's really helpful.
