PySide: Drag and drop files into QListWidget

问题 This is my first entry here so apologies for any newbie mistakes. I've searched both here and Google with no luck before posting. I want to be able to add images to a QListWidget, using drag and drop from a file browser. Dropping a valid file on the list widget also needs to trigger a function in the main class of my app, and pass it the image path. I found this code that does exactly that, but for PyQt4. Importing QtCore and QtGui from PySide instead of PyQt4 produces a segmentation fault

问题 I need to include text and greek symbols (for simple mathematical equations) in the different options proposed by a QListWidget in a '.ui' file (I use to work with Qt Designer and I like python if it matters). I want the options to appear like this: theta = phi^2 (toto et al.) theta = phi^2.5 (tata et al.) theta = 1-log(phi/2) (mister brown et al.) ... with 'theta' and 'phi' replaced by their symbol. Strangely, this turns out to be not so simple... How to define several fonts in one line of a

PyQt5 ListWidget add list items

由 怎甘沉沦 提交于 2020-01-03 19:40:30
问题 while learning PyQt5 i found a little problem( maybe a bug) in the ListWidget Widget (and all other widgets) the ListWidget have a addItem method overloaded : ( the code is in c++ but this is the same interface in pyqt ) void addItem(const QString &label) void addItem(QListWidgetItem *item) void addItems(const QStringList &labels) so the problem is that in PyQt5 there is no more QStringList type, and i should use a simple list of strings instead of the QStringList but when i receive and error

Drag'N'Drop custom widget items between QListWidgets

问题 i am currently working on a Python program, where i want to move items from one QListWidget to another with Drag and Drop. i read this thread, and implemented the Drag and Drop as described. It works with standard QListWidgetItems. The Problem is, i wanna do this custom widgets inside the QListWidgetItems, as described here, to store an icon and several lines into 1 QListWidgetItem. So when i now drag and drop an item into another list, it is empty, because it seems just to move/copy the

Can't change state of checkable QListViewItem with custom widget

问题 I have a QListWidget where I want to add a bunch of items with a custom widget: listWidget = QListWidget() item = QListWidgetItem() item.setFlags(item.flags() | Qt.ItemIsUserCheckable) item.setCheckState(Qt.Unchecked) listWidget.addItem(item) widget = MyLabelAndPushButton() item.setSizeHint(widget.sizeHint()) listWidget.setItemWidget(item, widget) As the name suggests MyLabelAndPushButton is just a widget containing a QLabel and a QPushButton in a layout. The problem is that I can not use the
