我认为PySide小部件的重绘问题。如何强制窗口小部件(或整个窗口/应用程序)在方法中间重新绘制?
def on_button_clicked():
window.resultTextEdit.setPlainText("Parsing file...")
# indicate delay, this message should be visible while parsing
# but in fact it never appears
# can I force a repaint here?
result = parse() # (takes a little while)
window.resultTextEdit.setPlainText(result)
# display the results once done
app = QApplication(sys.argv)
window = QtUiTools.QUiLoader().load("application.ui")
window.userButton.clicked.connect(on_button_clicked)
window.show()
sys.exit(app.exec_())
答案 0 :(得分:1)
对于在活动过程中需要重新绘制的任何窗口小部件,您只需拨打widget.repaint()
即可。请注意,其余的UI在重绘期间没有响应(这对于一次性通话是好的,但如果您重复重新绘制则不行。)
