Hi everyone,

I'm trying to develop a custom QtabWidget which can auto-hide by clicking on a button placed in the widget tab. Here is a sample code:

Qt Code: 
  1. from PyQt4.QtCore import *
  2. from PyQt4.QtGui import *
  3.  
  4. class HidingTabWidget(QTabWidget):
  5.     def __init__(self, parent):
  6.         super(QTabWidget, self).__init__(parent)  
  7.         self.show_tab = True
  8. 	self.max_height = 1000000
  9.  
  10.     def OnHideShow(self, event):
  11. 	self.show_tab = not self.show_tab
  12. 	if self.show_tab:
  13. 	    self.setFixedHeight(self.h)
  14. 	    self.setMinimumHeight(2*self.tb_h)
  15. 	    self.setMaximumHeight(self.max_height)
  16. 	else:  
  17. 	    self.h = self.height()
  18. 	    self.setFixedHeight(self.tb_h)
  19.         print self.height()
  20.  
  21.     def AddTab(self, widget, label):
  22. 	self.addTab(widget, label)
  23. 	index = self.indexOf(widget)
  24.         self.tabBar().setTabText(index, label)
  25. 	button = QPushButton(self)
  26.         button.setMaximumSize(16,16)
  27. 	self.tabBar().setTabButton(index, QTabBar.RightSide, button)  
  28.         button.clicked.connect(self.OnHideShow)	   
  29. 	self.tb_h = self.tabBar().height()-7
  30. 	self.setMinimumHeight(2*self.tb_h)
  31. 	self.setMaximumHeight(self.max_height)
  32.  
  33.  
  34. class Panel(QWidget):
  35.     def __init__(self, parent=None):
  36.         QWidget.__init__(self)
  37.  
  38. 	l = QVBoxLayout(self)
  39.         splitter = QSplitter(self)
  40.         splitter.setOrientation(Qt.Vertical)
  41.         frame1 = QFrame(splitter)
  42. 	frame1.setMinimumHeight(50)
  43. 	tab_table = HidingTabWidget(splitter)
  44.  
  45. 	l.addWidget(splitter)	
  46. 	tab_table.AddTab(QTableView(), "Table") 
  47.  
  48. 	self.setLayout(l)
  49. 	self.resize(600,400)
  50.  
  51. if __name__ == "__main__" :
  52.     import sys, os
  53.  
  54.     a = QApplication(sys.argv)
  55.     dia = Panel()
  56.     dia.show()
  57.     a.exec_()
To copy to clipboard, switch view to plain text mode 

If you click on the tab button, the widget collapses as I expect and its size cannot be changed. If you then re-click it, the widget original size is restored. The problem arises if I try to resize the widget when it is collapsed. If you try that and then re-click the tab button, the height of the widget is set to its minimum value, even if self.height() returns the correct height value. Is there anything I am missing?

Thanks in advance for your help!
