Python PYQT Tabs outside app window [why] -


tabs added before app.exec_() called , act other tabs u met, though if adding after app.exec_() call makes new tab 'detach' main app window. pic below :)

why? how can make move inside window?

import threading import time import sys  pyqt5.qtwidgets import qapplication pyqt5.qtwidgets import qformlayout pyqt5.qtwidgets import qlineedit pyqt5.qtwidgets import qtabwidget pyqt5.qtwidgets import qtextedit pyqt5.qtwidgets import qwidget  class atry(threading.thread):     def __init__(self):         super().__init__()      def run(self):         time.sleep(1)         anothertextedit = qtextedit()         anotherlineedit = qlineedit()         anotherlayout = qformlayout()         anotherlayout.addrow(anothertextedit)         anotherlayout.addrow(anotherlineedit)         anothertab = qwidget()         anothertab.setlayout(anotherlayout)         md.addtab(anothertab, "outside")  app = qapplication(sys.argv) md = qtabwidget()  atextedit = qtextedit() alineedit = qlineedit() layout = qformlayout() layout.addrow(atextedit) layout.addrow(alineedit) thistab = qwidget() thistab.setlayout(layout) md.addtab(thistab, "inside")  = atry() a.start() md.show()  app.exec_()

screen describing problem

it works qtimer or signals:

import sys import time  pyqt5.qtcore import qobject pyqt5.qtcore import qthread pyqt5.qtcore import pyqtsignal pyqt5.qtwidgets import qapplication pyqt5.qtwidgets import qformlayout pyqt5.qtwidgets import qlineedit pyqt5.qtwidgets import qtabwidget pyqt5.qtwidgets import qtextedit pyqt5.qtwidgets import qwidget   class atry(qthread):     def __init__(self, pointer):         super().__init__()         self.pointer = pointer      def run(self):         time.sleep(2)         self.pointer.emit()   def addthetab():     anothertextedit = qtextedit()     anotherlineedit = qlineedit()     anotherlayout = qformlayout()     anotherlayout.addrow(anotherlineedit)     anotherlayout.addrow(anothertextedit)     anothertab = qwidget()     anothertab.setlayout(anotherlayout)     md.addtab(anothertab, "whatever")   class myqobject(qobject):     trigger = pyqtsignal()      def __init__(self):         super().__init__()      def connect_and_get_trigger(self):         self.trigger.connect(addthetab)         return self.trigger      def getgfx(self):         app = qapplication(sys.argv)         md = qtabwidget()         md.show()         return app, md   obj = myqobject() app, md = obj.getgfx() addthetab() = atry(obj.connect_and_get_trigger()) a.start()  # timer = qtimer() # timer.timeout.connect(proba) # timer.start(3000)  app.exec_()

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
