Retrieve QTableWidget name when clicked/select cells in tablewdiget
How can i get the tablewidget name when i select any cell or click on any cell in a particulart tablewidget?
I tried using KeyPressEvent for this purpose, but not able to figure out which function do i need to use. Can anyone help me on this?
What do you mean by "tablewidget name" ?
Do you mean the text on the item(s) you click on ?
There is signals for that.
If you can have one or more selected, there is also
@mrjj So I have multiple tablewidgets in my GUI. I actually need to find the selected cell/item falls under which tablewidget? Is there any signal for that?
So whenever i select any item or cell in a tablewidget, it should give me the tablewidget's name.
But how come there can be any doubts ??
Do you have hook all tablewidgets to same slot or how come its even an issue ?
You have to explain why you need this as normally its non issue :)
u want to hangle item slection from same slot for all tablewidgets or why
do u need name ?

@mrjj Well, the bigger picture is, I want to copy selected cells irrespective of the tablewidget I choose. Currently, I have a code by which I can copy selected cells for a particular table. But I want to make it dynamic in the sense that I do not have to provide tablewidget name manually. It should automatically understand which tablewidget has the selected cells.
def keyPressEvent(self, e): if (e.modifiers() & QtCore.Qt.ControlModifier): self.table = self.ui.tableWidget selected = self.table.selectedRanges() s = '' if e.key() == QtCore.Qt.Key_C: #copy if self.table.horizontalHeaderItem(0): s = '\t'+"\t".join([str(self.table.horizontalHeaderItem(i).text()) for i in xrange(selected.leftColumn(), selected.rightColumn()+1)]) s = s + '\n' for r in xrange(selected.topRow(), selected.bottomRow()+1): if self.table.verticalHeaderItem(0): s += self.table.verticalHeaderItem(r).text() + '\t' for c in xrange(selected.leftColumn(), selected.rightColumn()+1): try: s += str(self.table.item(r,c).text()) + "\t" except AttributeError: s += "\t" s = s[:-1] + "\n" #eliminate last '\t' self.clip.setText(s)
Ok so its for generic handling.
If using signals
there is the sender() to know whom emitted the signal.
I assume QTableWidgetItem have a parent or something like that that would also tell you name.
(dont have docs here. if not, you can subclass and add it)
and there is QTableWidgetItem::setData() where you can simply stuff the info and read when needed.
( this should be pretty easy even if a bit wastefull since all items then have it :)
@mrjj i tried using self.sender(), but it gives the mainwindow name.
How do i subclass it and get the name?
@Piyush Where did you use sender()?
@jsulm I added it in the keypressevent function shared above, which gives me mainwindow as the sender. This was my bad.
However, now i created a cellclicked signal for all the tables as below to get the name and it works. Now the issue is keypressevent function is not responding (not copying the selected values). I made self.table as a class global variable, in which i have both the functions
def __init__(self): self.table = '' self.ui.table1.cellClicked.connect(self.get_obj_name) self.ui.table2.cellClicked.connect(self.get_obj_name) self.ui.table3.cellClicked.connect(self.get_obj_name) def get_obj_name(self, row, col): abc= self.sender() table = abc.objectName() self.table = "self.ui." + table
its a type issue i guess. The string i made is <type 'unicode'>, however, I should pass <class 'PyQt5.QtWidgets.QTableWidget'>
How do i correct this issue?
Got it. just had to equate self.table = QTableWdiget().
Thanks guys, for the patience and help.
