Is there anyway to add like a button in qtablewidget? But the date within the cell would stil have to be displaying, for example if an user double clicked a cell, could i send a signal like a button? Thanks!

edititem():

def editItem(self,clicked):
 if clicked.row() == 0:
 #go to tab1
 if clicked.row() == 1:
 #go to tab1
 if clicked.row() == 2:
 #go to tab1
 if clicked.row() == 3:
 #go to tab1

table trigger:

self.table1.itemDoubleClicked.connect(self.editItem)

You have a couple of questions rolled into one...short answer, yes, you can add a button to a QTableWidget - you can add any widget to the table widget by calling setCellWidget:

# initialize a table somehow
table = QTableWidget(parent)
table.setRowCount(1)
table.setColumnCount(1)

# create an cell widget
btn = QPushButton(table)
btn.setText('12/1/12')
table.setCellWidget(0, 0, btn)

But that doesn't sound like what you actually want.

It sounds like you want to react to a user double-clicking one of your cells, as though they clicked a button, presumably to bring up a dialog or editor or something.

If that is the case, all you really need to do is connect to the itemDoubleClicked signal from the QTableWidget, like so:

def editItem(item):
 print 'editing', item.text() 

# initialize a table widget somehow
table = QTableWidget(parent)
table.setRowCount(1)
table.setColumnCount(1)

# create an item
item = QTableWidgetItem('12/1/12')
table.setItem(0, 0, item)

# if you don't want to allow in-table editing, either disable the table like:
table.setEditTriggers( QTableWidget.NoEditTriggers )

# or specifically for this item
item.setFlags( item.flags() ^ Qt.ItemIsEditable)

# create a connection to the double click event
table.itemDoubleClicked.connect(editItem)
