问题 I have a program that creates a number of qlineedits and buttons depending on the users input: On the image above 4 lines have been added with a button after the grayed out "Next" button was clicked. Now I want to get the input from the user into a function when the corresponding button is clicked (Click "Create Shot 1! --> goto a function with "exShot1" passed as an argument). The thing is I have no idea how to get the names of each qline and button when they are created in a loop. I guess I

问题 I have tried to implement in Pyside the method described in How to distinguish between mouseReleaseEvent and mousedoubleClickEvent on QGrapnhicsScene, but I had to add a crufty flag to keep it from showing single click after the second button release in a double click. Is there a better way? import sys from PySide import QtGui, QtCore class Example(QtGui.QWidget): def __init__(self): super(Example, self).__init__() """an attempt to implement https://stackoverflow.com/questions/18021691/how-to

问题 How do I get a link's URL when clicking on the link? If I have a link in the A tag, it's simple: just connect linkClicked(const QUrl&) signal to specific slot. But if I have a table with an "onClick" event on its cell (generated html: "<td onClick=\"window.location.href='" + link_ + "';\" ......blahblahblah"), it's not working. Why? 回答1: As it's name suggests, the linkClicked signal is only emitted whenever a link is activated. But you can intercept all navigation requests by reimplementing

问题 My knowledge of Python is still pretty basic, and I am only now trying to wrap my head around how to use / call libraries from within Maya. (Because I need to create a basic UI from QT Designer and have it be opened in Maya after converting it to a .py file) After I learned to properly convert a .ui to a .py, I now get this error in Maya "Module use of python34.dll conflicts with this version of Python" I tried following what was said here and here, but even then - after setting these

问题 This might be a very uninformed question. I've been trying to figure out QGraphics* , and have run into a problem when trying to move an item (a pixmap) relative to or inside of the QGraphicsView . class MainWindow(QMainWindow,myProgram.Ui_MainWindow): def __init__(self): super().__init__() self.setupUi(self) self.scene = QGraphicsScene() self.graphicsView.setScene(self.scene) pic = QPixmap('myPic.png') self.scene.addPixmap(pic) print(self.scene.items()) This is the relevant part of the

问题 I've implemented a version of the worker pattern that is described in the Qt Threading docs. I'm using Signals/Slots to send data between the worker thread and the main thread. When defining the Signal , I've set the argument signature type to object since I believe it should allow me to pass any python object through the Signal . result_ready = QtCore.Signal(object) However, when I try to pass None through the Signal it crashes python. This only happens when trying to pass the Signal across

问题 HTTP 1.1 supports persistent connection by default, so I want to send my a second http request using the same connection that was setup when the first HTTP request was made. how can this be achieved through Qt? If I simply make the second request after the first one finished like the following manager->get(QNetworkRequest(QUrl("http://qt-project.org"))); it seems a new TCP connection to the server will be initiated (I have checked with a network sniffer) The experiment also says: If the reply

问题 I'm attempting to use QThreads to update my custom tool's Qt-based UI inside of Maya. I have a thread that executes arbitrary methods and returns the result via an emitted signal, which I then use to update my UI. Here's my custom QThread class: from PySide import QtCore class Thread(QtCore.QThread): result = QtCore.Signal(object) def __init__(self, parent, method, **kwargs): super(Thread, self).__init__(parent) self.parent = parent self.method = method self.kwargs = kwargs def run(self):

问题 I'm currently writing a GUI for rvplayer that shall enable artists to automatically render dailies with slate and burn-in information. The GUI is written with PySide and scripted in Python 2.7. My problem is that upon calling my process and updating my QProgressBar with the stdout the GUI freezes. I know that this is a common problem and that it can probably be solved with processEvents() somehow, but I know far too little about threading and process loops to get my head around this issue.

问题 Is there some way to make sure that updating an existing QTreeWidgetItem or inserting a new one ensures that the item is unique among its siblings based on the value of a single column? I have tried to do something like this with a QTreeView and my own custom model and have gotten it to work, but some advanced features like moving items with drag and drop are eluding me. I figure, the QTreeWidget and QTreeWidgetItem classes ought to get more of this type of stuff for free and ought to cause
