Hello,
I’m currently writing a UI in Maya using Pyside2. This UI has a number of tabs. Each Tab having 3 child tabs of model names within the tabs listWidget. I’m having a problem to query the active tab. I use the self.mytab.currentWidget() method that returns a pointer (PySide2.QtWidgets.QWidget(0x2439df45d30) at 0x0000024378A0B688) which I store in a variable. But how do I use this pointer to access the selected tabs name?
Here is some code to shed some light:
# self.tab_piece is a QtWidgets.QTabWidget() that has a number of tabs with child tabs that will
# be queried for selected.
# Get selected pieces tab
index = self.tab_pieces.currentIndex()
tab_text = self.tab_pieces.tabText(index)
# The above will only give me the parent name and not the active child tab name
current_tab = self.tab_pieces.currentWidget()
# the above returns this PySide2.QtWidgets.QWidget(0x2439df45d30) at 0x0000024378A0B688
# how to I query current_tab tab name?
You could traverse through children of that widget, and find your tabs among them, and do same logic - check for currentIndex, and get tabText (tab label) at that index. Something like this:
tab = QtWidgets.QTabWidget() # parent tab, tabs_pieces in your snippet
widget = tab.currentWidget()
children = widget.children() # children widgets
for child in children:
if isinstance(child, PySide2.QtWidgets.QTabBar): # is it QTabBar, since there will be other widgets
current_index = child.currentIndex() # get current tab's index
tab_text = child.tabText(current_index) # get label of current tab
P.S. If your children tab widgets aren’t QTabBar, replace instance checking with correct type.
Or avoid ‘if isinstance(…):’ check altogether, and wrap <current_index, tab_text> in try-except block.
Hey bjeDark, thanks for pointing me in the right direction. I got it working!
I used QTabWidget instead of QTabBar.
Her is a snippet of the code to help others. Note: I was querying the active tab from a parent tab that had 3 child tabs to which one of these will be active:
# Get selected parent tab and it's selected tab category name.
# self.tab_pieces is my parent tab
tab_pieces_index = self.tab_pieces.currentIndex()
tab_pieces_text = self.tab_pieces.tabText(tab_pieces_index) # Get tab category name
print(f"Tab Pieces category name: {tab_pieces_text}")
current_tab = self.tab_pieces.currentWidget()
children = current_tab.children() # Get parent tab children, list pointer to widgets.
child_tab_text = ""
# Find tab widget within children. This will get the active tab!
for child in children:
if isinstance(child, QtWidgets.QTabWidget):
current_index = child.currentIndex() # get current tab's index
child_tab_text = child.tabText(current_index) # get label of current tab
print(f"Current active tab: {tab_pieces_text}_{child_tab_text}")
