Force Qt/PyQt/PySide QTabWidget to resize to active tab

由 对着背影说爱祢 提交于 2020-03-03 10:13:10
问题 I have a QTabWidget working correctly except that it doesn't re-size how I would expect it. There are 2 tabs in the widget. Each has a QVBoxLayout with widgets in it. The VBox also works as expected. The issue is that the first tab has more widgets in its layout than the second tab. When viewing the first tab, the tab sizes to appropriately contain the widgets inside of it. However, when viewing the second tab, the tab widget stays the same size of the first, instead of re-sizing to the

Fixing Threads in PySide2

由 那年仲夏 提交于 2020-02-25 23:09:06
问题 I have programmed an application using PySide2 with some 800 lines of code and now when I want to show a variable in the progress bar it crashes after a short while without any warning. Silently. Just now it dawned on me that my whole approach to this GUI building is probably incorrect. Can this code be saved somehow so that it can via signals set this progress bar from inside the thread without the application crashing? EDIT: this minimal code works and crashes but needs a small ui file.

PySide: Drag and drop files into QListWidget

由 一笑奈何 提交于 2020-02-20 10:39:51
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

Signal in PySide not emitted when called by a timer

由 北慕城南 提交于 2020-02-07 23:46:11
问题 I need to emit a signal periodically. A timer executes certain function, which emits the signal that I want. For some reason this function is not being emitted. I was able to reproduce the error on minimal code (see further down). If I do the same without the timer everything works: from threading import Timer import time from PySide import QtCore class testSignals(QtCore.QObject): signal = QtCore.Signal(); def __init__(self): QtCore.QObject.__init__(self) def run(self): self.signal.emit()
