Re: Using PyQT with QT Designer

Thanks. I probably will do exactly like you suggested later on. But, those two lines have solved the problem I had and I can work on the actual program now. I can come back to the GUI later.

Thanks for the manual. I will look into it but all the examples are probably c++. Ive tried zetcode and some of the other tutorials. That's the problem though.

The problem is, when I try to follow zetcode and other tutorials about how to import and use my form as designed by qt designer and run through pyuic4 it doesn't seem to even notice my ui file...and certainly isnt acting on it.

Again thoughI'm finished with QT Designer. I have the finished product I want exactly like I want it. But, as ive shown in the screenshots, I'm doing exactly what ive seen in zetcode and other tutorials but It doesn't seem to incorporate and act upon that ui file. The first thing you notice is that it doesn't resize the main window to 800x600...which is one of the first lines in the ui file.

You don't say what the name of the generated file is, but perhaps since the source file was window.ui, the generated one is window.py My guess is that when you do the from window import Ui_MainWindow it is finding some OTHER window.py file.

Thank you. I just deleted all of them, reran pyuic4 on window.ui and regenerated window.py just to make sure. Unfortunately, I get the same problem.

This is what I tried: from PyQt4.QtCore import * from PyQt4.QtGui import * from window import Ui_MainWindow THUMBNAIL_SIZE = 128 SPACING= 10 IMAGES_PER_ROW = 4 class MainWindow(QMainWindow, Ui_MainWindow): def __init__(self): super(MainWindow, self).__init__() #self.setWindowTitle(Image Gallery) centralWidget=QWidget(self) l=QVBoxLayout(centralWidget) self.tableWidget=TableWidget(self) l.addWidget(self.tableWidget) self.listWidget=ListWidget(self) l.addWidget(self.listWidget) Ui_MainWindow.pushButton = QPushButton(self) l.addWidget(Ui_MainWindow.pushButton) self.pushButton_2 = QPushButton(self) l.addWidget(self.pushButton_2) self.pushButton_3 = QPushButton(self) l.addWidget(self.pushButton_3) self.setCentralWidget(centralWidget) picturesPath=QDesktopServices.storageLocation(QDesktopServices.PicturesLocation) pictureDir=QDir(picturesPath) pictures=pictureDir.entryList(['*.jpg','*.png','*.gif']) rowCount=len(pictures)//IMAGES_PER_ROW if len(pictures)%IMAGES_PER_ROW: rowCount+=1 self.tableWidget.setRowCount(rowCount) row=-1 for i,picture in enumerate(pictures): col=i%IMAGES_PER_ROW if not col: row+=1 self.tableWidget.addPicture(row, col, pictureDir.absoluteFilePath(picture)) class ListWidget(QListWidget): def __init__(self, parent=MainWindow, **kwargs): QListWidget.__init__(self, parent, **kwargs) self.setGeometry(QRect(70, 400, 661, 181)) class TableWidget(QTableWidget): def __init__(self, parent=MainWindow, **kwargs): QTableWidget.__init__(self, parent, **kwargs) self.setIconSize(QSize(128,128)) self.setColumnCount(IMAGES_PER_ROW) self.setGridStyle(Qt.NoPen) # Set the default column width and hide the header self.verticalHeader().setDefaultSectionSize(THUMBNAIL_SIZE+SPACING) self.verticalHeader().hide() # Set the default row height and hide the header self.horizontalHeader().setDefaultSectionSize(THUMBNAIL_SIZE+SPACING) self.horizontalHeader().hide() # Set the table width to show all images without horizontal scrolling self.setMinimumWidth((THUMBNAIL_SIZE+SPACING)*IMAGES_PER_ROW+(SPACING*2)) def addPicture(self, row, col, picturePath): item=QTableWidgetItem() # Scale the image by either height or width and then 'crop' it to the # desired size, this prevents distortion of the image. p=QPixmap(picturePath) if p.height()p.width(): p=p.scaledToWidth(THUMBNAIL_SIZE) else: p=p.scaledToHeight(THUMBNAIL_SIZE) p=p.copy(0,0,THUMBNAIL_SIZE,THUMBNAIL_SIZE) item.setIcon(QIcon(p)) self.setItem(row,col,item) if __name__==__main__: from sys import argv, exit a=QApplication(argv) m=MainWindow() m.show() m.raise_() exit(a.exec_()) and I'm getting this (not even starting at 800x600): http://i.imgur.com/Xg4Qnzl.png instead of this as it was designed in QT Designer: http://i.imgur.com/ULRolq8.png Here is the ui file window.py that I got by running pyuic4 on window.ui: # -*- coding: utf-8 -*- # Form implementation generated from reading ui file 'window.ui' # # Created by: PyQt4 UI code generator 4.9.6 # # WARNING! All changes made in this file will be lost! from PyQt4 import QtCore, QtGui try: _fromUtf8 = QtCore.QString.fromUtf8 except AttributeError: def _fromUtf8(s): return s try: _encoding = QtGui.QApplication.UnicodeUTF8 def _translate(context, text, disambig): return QtGui.QApplication.translate(context, text, disambig, _encoding) except AttributeError: def _translate(context, text, disambig): return QtGui.QApplication.translate(context, text, disambig) class Ui_MainWindow(object): def setupUi(self, MainWindow): MainWindow.setObjectName(_fromUtf8(MainWindow)) MainWindow.resize(800, 600) MainWindow.setAnimated(False) self.centralwidget = QtGui.QWidget(MainWindow) self.centralwidget.setObjectName(_fromUtf8(centralwidget)) self.tableWidget = QtGui.QTableWidget(self.centralwidget) self.tableWidget.setGeometry(QtCore.QRect(70, 20, 661, 381))
Using PyQT with QT Designer
I'm learning Python and I have a problem. I've asked the question everywhere and no one helps me, so I'm hoping someone here will. I am making a program that shows album covers and you click on the album cover in the top window. In the bottom window, the list of songs appear and you can click the individual song to play it. It's going to be a media player for children. I'm thinking I'll be able to use a dict and have the album as the key and the list of songs as the value to accomplish this. Right now, I'm just using my picture directory to try and get the basic layout right. I designed a form in QT Designer: http://i.imgur.com/Wrp1zHW.png Here is my gui file I got from running pyuic4 on the ui file: # -*- coding: utf-8 -*- # Form implementation generated from reading ui file 'window.ui' # # Created by: PyQt4 UI code generator 4.9.6 # # WARNING! All changes made in this file will be lost! from PyQt4 import QtCore, QtGui try: _fromUtf8 = QtCore.QString.fromUtf8 except AttributeError: def _fromUtf8(s): return s try: _encoding = QtGui.QApplication.UnicodeUTF8 def _translate(context, text, disambig): return QtGui.QApplication.translate(context, text, disambig, _encoding) except AttributeError: def _translate(context, text, disambig): return QtGui.QApplication.translate(context, text, disambig) class Ui_MainWindow(object): def setupUi(self, MainWindow): MainWindow.setObjectName(_fromUtf8(MainWindow)) MainWindow.resize(800, 600) self.centralwidget = QtGui.QWidget(MainWindow) self.centralwidget.setObjectName(_fromUtf8(centralwidget)) self.tableWidget = QtGui.QTableWidget(self.centralwidget) self.tableWidget.setGeometry(QtCore.QRect(70, 20, 661, 381)) self.tableWidget.setObjectName(_fromUtf8(tableWidget)) self.tableWidget.setColumnCount(0) self.tableWidget.setRowCount(0) self.listWidget = QtGui.QListWidget(self.centralwidget) self.listWidget.setGeometry(QtCore.QRect(70, 400, 661, 181)) self.listWidget.setObjectName(_fromUtf8(listWidget)) MainWindow.setCentralWidget(self.centralwidget) self.retranslateUi(MainWindow) QtCore.QMetaObject.connectSlotsByName(MainWindow) def retranslateUi(self, MainWindow): MainWindow.setWindowTitle(_translate(MainWindow, MainWindow, None)) Now, according to websites I read, I should just have to add the following to my program to get it to use the form: from window import Ui_MainWindow class MainWindow(QMainWindow, Ui_MainWindow): def __init__(self, parent=None, **kwargs): super(MainWindow, self).__init__(parent) self.setupUi(self) and here is my program: from PyQt4.QtCore import * from PyQt4.QtGui import * from window import Ui_MainWindow THUMBNAIL_SIZE = 128 SPACING= 10 IMAGES_PER_ROW = 5 class TableWidget(QTableWidget): def __init__(self, parent=None, **kwargs): QTableWidget.__init__(self, parent, **kwargs) self.setIconSize(QSize(128,128)) self.setColumnCount(IMAGES_PER_ROW) self.setGridStyle(Qt.NoPen) # Set the default column width and hide the header self.verticalHeader().setDefaultSectionSize(THUMBNAIL_SIZE+SPACING) self.verticalHeader().hide() # Set the default row height and hide the header self.horizontalHeader().setDefaultSectionSize(THUMBNAIL_SIZE+SPACING) self.horizontalHeader().hide() # Set the table width to show all images without horizontal scrolling self.setMinimumWidth((THUMBNAIL_SIZE+SPACING)*IMAGES_PER_ROW+(SPACING*2)) def addPicture(self, row, col, picturePath): item=QTableWidgetItem() # Scale the image by either height or width and then 'crop' it to the # desired size, this prevents distortion of the image. p=QPixmap(picturePath) if p.height()p.width(): p=p.scaledToWidth(THUMBNAIL_SIZE) else: p=p.scaledToHeight(THUMBNAIL_SIZE) p=p.copy(0,0,THUMBNAIL_SIZE,THUMBNAIL_SIZE) item.setIcon(QIcon(p)) self.setItem(row,col,item) class MainWindow(QMainWindow, Ui_MainWindow): def __init__(self, parent=None, **kwargs): super(MainWindow, self).__init__(parent) self.setupUi(self) centralWidget=QWidget(self) l=QVBoxLayout(centralWidget) self.tableWidget=TableWidget(self) l.addWidget(self.tableWidget) self.setCentralWidget(centralWidget) picturesPath=QDesktopServices.storageLocation(QDesktopServices.PicturesLocation) pictureDir=QDir(picturesPath) pictures=pictureDir.entryList(['*.jpg','*.png','*.gif']) rowCount=len(pictures)//IMAGES_PER_ROW if len(pictures)%IMAGES_PER_ROW: rowCount+=1
