QTabBar Indexing is wrong for right mouse click - xenas - Jan-04-2019
Hi all, I am trying to grab ahold of the mouse position + right mouse click on QTabBar where it will pops up a message to User if they want to remove the said tab.
(Pardon the vague design) This is what my QTabBar looks like:
| + | food | snacks | drinks |However, in my following code, whenever I tried to print out the index as I do a right-mouse click on the tabs, the returned index value is wrong.
It seems to have taken into account of the ‘+’ button as it is indicating as index 0 where index 0 should actually starts from the ‘food’ tab onwards.
Here is my code:
class MyWin(QtGui.QMainWindow):
def __init__(self, parent=None):
super(MyWin, self).__init__()
central_widget = QtGui.QWidget()
self.setCentralWidget(central_widget)
vlay = QtGui.QVBoxLayout(central_widget)
hlay = QtGui.QHBoxLayout()
vlay.addLayout(hlay)
vlay.addStretch()
self.add_button = QtGui.QToolButton()
self.tab_bar = QtGui.QTabBar(self)
self.add_button.setIcon(QtGui.QIcon('add.png'))
self.add_button.setMenu(self.set_menu())
self.add_button.setPopupMode(QtGui.QToolButton.InstantPopup)
self.tab_bar.setTabButton(
0,
QtGui.QTabBar.ButtonPosition.RightSide,
self.add_button
)
hlay.addWidget(self.add_button)
hlay.addWidget(self.tab_bar)
def set_menu(self):
menu_options = ['food', 'drinks', 'snacks']
qmenu = QtGui.QMenu(self.add_button)
for opt in menu_options:
qmenu.addAction(opt, partial(self.set_new_tab, opt))
qmenu.addAction
return qmenu
def set_new_tab(self, opt):
self.tab_bar.addTab(opt)
def mousePressEvent(self, event):
if event.button() == QtCore.Qt.RightButton:
index = self.tab_bar.tabAt(event.pos())
print index
menu = QtGui.QMenu(self)
action = menu.addAction('Remove tab', partial(self.removal_tab, index))
else:
super(MyWin, self).mousePressEvent(event)
def removal_tab(self, index):
self.tab_bar.removeTab(index)
my_win = MyWin()
my_win.show()Appreciate for any insights and many thanks in advance for any response!

That's only a part of the code.
what is opt, partial ?
and I miss something like this at the end
if __name__ == '__main__':
import sys
app = GtGui.QApplication(sys.argv)
my_win = MyWin()
my_win.show()
app.exec()

Hi Axel,
partial are part of the import module that I did not added in my above code.And so it should be (I can't seem to find the 'edit; to my post):
from functools import partial
class MyWin(QtGui.QMainWindow):
def __init__(self, parent=None):
super(MyWin, self).__init__()
central_widget = QtGui.QWidget()
self.setCentralWidget(central_widget)
vlay = QtGui.QVBoxLayout(central_widget)
hlay = QtGui.QHBoxLayout()
vlay.addLayout(hlay)
vlay.addStretch()
self.add_button = QtGui.QToolButton()
self.tab_bar = QtGui.QTabBar(self)
self.add_button.setIcon(QtGui.QIcon('add.png'))
self.add_button.setMenu(self.set_menu())
self.add_button.setPopupMode(QtGui.QToolButton.InstantPopup)
self.tab_bar.setTabButton(
0,
QtGui.QTabBar.ButtonPosition.RightSide,
self.add_button
)
hlay.addWidget(self.add_button)
hlay.addWidget(self.tab_bar)
def set_menu(self):
menu_options = ['food', 'drinks', 'snacks']
qmenu = QtGui.QMenu(self.add_button)
for opt in menu_options:
qmenu.addAction(opt, partial(self.set_new_tab, opt))
qmenu.addAction
return qmenu
def set_new_tab(self, opt):
self.tab_bar.addTab(opt)
def mousePressEvent(self, event):
if event.button() == QtCore.Qt.RightButton:
index = self.tab_bar.tabAt(event.pos())
print index
menu = QtGui.QMenu(self)
action = menu.addAction('Remove tab', partial(self.removal_tab, index))
else:
super(MyWin, self).mousePressEvent(event)
def removal_tab(self, index):
self.tab_bar.removeTab(index)
my_win = MyWin()
my_win.show()opt is part of the menu options as stated in line 28.This is a complete code despite I did not added in the execution code as you have defined, as the tool is still operatable.
