  • QTWebkit 4.6 and ico images, Rendering problem

    - by Red Serpent
    Hi I have a local html file which I'm trying to view using QTWebKit, there are some images in the file which are of type ".ico" which seems that QTWebKit is not able to render them as it gives a question mark icon instead. I tried opening the html file in firefox and its working fine and all images gets rendered. My question is, does QTWebKit support ico images, and if it does... what should I do to enable webkit to render ico images? Regards

  • insertRecord into QSqlTableModel fails, but item appears in QListView

    - by Anteru
    I got a pretty weird problem with a QSqlTableModel. The underlying SQL Database has a constraint Title UNIQUE. If I add a record which violates the constraint using insertRecord, the call fails (return value is false.) However, the view which uses the model displays the entry -- I have to manually remove it in order to get rid of it. How can I change this so the view does not get updated when an insertRecord fails? I would have assumed that the view gets only updated if there is really a change ...

  • Right clicking on QHeaderView inside of QTreeView

    - by taynaron
    I've written a descendant of QTreeView with multiple columns. I want to create a popup menu that appears whe nthe user right-clicks over the column headers. I have tried catching signals from QTreeView for this, but QTreeView doesn't seem to emit signals on the headers. QTreeView.header() does. I therefore believe I must either: 1: connect one of QHeaderView's signals to a popup function - I have been unable to find a signal that is triggered on a single right click - I have tried sectionClicked, sectionHandleDoubleClicked, sectionDoubleClicked, sectionPressed (not surprised the double click functions didn't catch a single right click - but they do catch a double right click) self.header().sectionClicked.connect(self.headerMenu) self.header().sectionHandleDoubleClicked.connect(self.headerMenu) self.header().sectionDoubleClicked.connect(self.headerMenu) self.header().sectionPressed.connect(self.headerMenu) or, 2: write a descendant of QHeaderView with my own MousePressEvent function, and use that for my headers. I have so far been unsuccessful in connecting the new header class to the QTreeView descendant. I keep getting a Segmentation Fault on runtime, with no more explanation. #in DiceView's init, where DiceHeaders is the QHeaderView descendant self.setHeader(DiceHeaders()) Any ideas?

  • Unit Testing in QTestLib - running single test / tests in class / all tests

    - by Dave
    I'm just starting to use QTestLib. I have gone through the manual and tutorial. Although I understand how to create tests, I'm just not getting how to make those tests convenient to run. My unit test background is NUnit and MSTest. In those environments, it was trivial (using a GUI, at least) to alternate between running a single test, or all tests in a single test class, or all tests in the entire project, just by clicking the right button. All I'm seeing in QTestLib is either you use the QTEST_MAIN macro to run the tests in a single class, then compile and test each file separately; or use QTest::qExec() in main() to define which objects to test, and then manually change that and recompile when you want to add/remove test classes. I'm sure I'm missing something. I'd like to be able to easily: Run a single test method Run the tests in an entire class Run all tests Any of those would call the appropriate setup / teardown functions.

  • Calling activateWindow on QDialog sends window to background

    - by Stan
    I am debugging certain application written with C++/Qt4. On Linux it has problems that with certain window managers (gnome-wm/metacity), the main window (based on QDialog) is created in the background (it's not raised). I managed to re-create the scenario using PyQt4 and following code: from PyQt4.QtCore import * from PyQt4.QtGui import * import sys class PinDialog(QDialog): def showEvent(self, event): QDialog.showEvent(self, event) self.raise_() self.activateWindow() if __name__ == "__main__": app = QApplication(sys.argv) widget = PinDialog() app.setActiveWindow(widget) widget.exec_() sys.exit(0) If I remove self.activateWindow() the application works as expected. This seems wrong, since documentation for activateWindow does not specify any conditions under which something like this could happen. My question is: Is there any reason to have activateWindow in showEvent in the first place? If there is some reason, what would be good workaround for focusing issues?

    What is the correct interpretation of the following segfault messages? segfault at 10 ip 00007f9bebcca90d sp 00007fffb62705f0 error 4 in libQtWebKit.so.4.5.2[7f9beb83a000+f6f000] segfault at 10 ip 00007fa44d78890d sp 00007fff43f6b720 error 4 in libQtWebKit.so.4.5.2[7fa44d2f8000+f6f000] segfault at 11 ip 00007f2b0022acee sp 00007fff368ea610 error 4 in libQtWebKit.so.4.5.2[7f2aff9f7000+f6f000] segfault at 11 ip 00007f24b21adcee sp 00007fff7379ded0 error 4 in libQtWebKit.so.4.5.2[7f24b197a000+f6f000]

  • PyQt: How to keep QTreeView nodes correctly expanded after a sort

    - by taynaron
    I'm writing a simple test program using QTreeModel and QTreeView for a more complex project later on. In this simple program, I have data in groups which may be contracted or expanded, as one would expect in a QTreeView. The data may also be sorted by the various data columns (QTreeView.setSortingEnabled is True). Each tree item is a list of data, so the sort function implemented in the TreeModel class uses the built-in python list sort: self.layoutAboutToBeChanged.emit() self.rootItem.childItems.sort(key=lambda x: x.itemData[col], reverse=order) for item in self.rootItem.childItems: item.childItems.sort(key=lambda x: x.itemData[col], reverse=order) self.layoutChanged.emit() The problem is that whenever I change the sorting of the root's child items (the tree is only 2 levels deep, so this is the only level with children) the nodes aren't necessarily expanded as they were before. If I change the sorting back without expanding or collapsing anything, the nodes are expanded as before the sorting change. Can anyone explain to me what I'm doing wrong? I suspect it's something with not properly reassigning QModelIndex with the sorted nodes, but I'm not sure.

  • get all running processes info using QProcess

    - by kaycee
    few days ago i asked about how to get all running processes in the system using QProcess. i found a command line that can output all processes to a file: C:\WINDOWS\system32\wbem\wmic.exe" /OUTPUT:C:\ProcessList.txt PROCESS get Caption this will create C:\ProcessList.txt file contains all running processes in the system. i wonder how can i run it using QProcess and take its output to a variable. it seems every time i try to run it and read nothing happens: QString program = "C:\\WINDOWS\\system32\\wbem\\wmic.exe"; QStringList arguments; arguments << "/OUTPUT:C:\\ProcessList.txt" <<"PROCESS"<< "get"<< "Caption"; process->setStandardOutputFile("process.txt"); process->start(program,arguments); QByteArray result = process->readAll(); i prefer not to create process.txt at all and to take all the output to a variable...

  • qtcreator keyboard problem: azerty/qwerty

    - by Allen
    I picked up the qt SDK and I've been trying it out. I'm working in English but I have a French AZERTY keyboard. When I run Qt Designer all is fine. When I run Qt Creator or Qt Designer from within Qt Creator things work as though I had a QWERTY keyboard, so I have to hit the "q" key to get an "a", etc. Qt Creator is version 1.3.1 and it is using Qt 4.6.2. My PC is running XP. What is going on and what is to be done? Any ideas? Editing a program in this setup is, of course, impossible! Luckily I discovered I can use an external editor, so I can use xemacs, which would be my first choice anyway, but this keyboard problem is a real nuisance! Thanks.

  • Save QList<int> to QSettings

    - by Tobias
    Hello, I want to save a QList<int> to my QSettings without looping through it. I know that I could use writeArray() and a loop to save all items or to write the QList to a QByteArray and save this but then it is not human readable in my INI file.. Currently I am using the following to transform my QList<int> to QList<QVariant>: QList<QVariant> variantList; //Temp is the QList<int> for (int i = 0; i < temp.size(); i++) variantList.append(temp.at(i)); And to save this QList<Variant> to my Settings I use the following code: QVariant list; list.setValue(variantList); //saveSession is my QSettings object saveSession.setValue("MyList", list); The QList is correctly saved to my INI file as I can see (comma seperated list of my ints) But the function crashes on exit. I already tried to use a pointer to my QSettings object instead but then it crashes on deleting the pointer ..

  • PyQt: Get the position of QGraphicsWidgets in a QGraphicsGridLayout

    - by Chris Phillips
    I have a fairly simple PyQt application in which I'm placing instances of a QGraphicsWidget in a QGraphicsGridLayout and want to connect the widgets with lines drawn with a QGraphicsPath. Unfortunately, no matter what I try, I always get (0, 0) back as the position for both the start and end widgets. I'm constructing the graph with a recursive function that adds widgets to the scene and layout. Once the recursive function is complete, the layout is added to a new widget, which is added to the scene to show everything. The edges are added to the scene as widgets are created. How do I get a non-zero position of any of the widgets in the grid layout?

    Hi everyone, I need to do some actions when item in QTreeWidget activates, but following code doestn't gives me expected result: class MyWidget(QTreeWidget): def __init__(self, parent=None): super(MyWidget, self).__init__(parent) self.connect(self, SIGNAL("activated(QModelIndex)"), self.editCell) def editCell(self, index): print index or class MyWidget(QTreeWidget): def __init__(self, parent=None): super(MyWidget, self).__init__(parent) self.connect(self, SIGNAL("itemActivated(QTreeWidgetItem, int)"), self.editCell) def editCell(self, item, column=0): print item What am i doing wrong or how to hadnle item activation in the right way?
