Having a QTableWidgets with a list of tables and two additional classes Combocells and Groupcells. They are shown with QTabWidget. I want to click and highlight a row or cell in the table then the two classes Combocells and Groupcells refreshs and loads into QTabWidget according to row of table.
The structure of files.
- Main.py
- Tablecells.py
- Combocells.py
- Groupcells.py
Visualisation
Update:
I have updated the code, signal and slot catch row number and send it. Despite by clicking on cells
Data and Valuetabs add to tabwidgets and removes, whenrow 0is selected. what I do not get is whenrow 1is selected, wellData and Valuetabs add to widget, make some changes incomboboxandQlineeditinside Data and Value to see, whenrow 2is clicked, wouldData and Valuereally add to tabwidget from beginning. I notice it does not update. I have tried withaddTabandinsertTabwithself.update(), still does not really process in a way I want to do.Could anyone know how to fix this issue? Review this piece of script which has problem.
class Tabwidget(QtWidgets.QWidget):
def __init__(self, parent=None):
super( Tabwidget, self).__init__()
-----------------------
@QtCore.pyqtSlot(int)
def rowselected_tables(self, row):
print('Row {} is selected.'.format(row))
if row > 0:
self.update()
#self.Tab.addTab( self.Combo, 'Data')
#self.Tab.addTab( self.Group, 'Values')
self.Tab.insertTab( 1, self.Combo, 'Data')
self.Tab.insertTab( 2, self.Group, 'Values')
I want to load data and values tabs accordingly to number of rows. for example when user clicks and highlights a certain row inside the table the classes are loaded and any change in Data and Values for that row should remain, when user highlight another row then new Data and Value appears, but in case of return to previous highlighted and clicked row or cell any previous changes in Data and Values would appear again.
I want to print something like.
Row x is highligted: Data : ( L6, 0,10) and Value: (10)

I really do not know how to achieve that. It might be some special scripts in PyQT5 to do the task. I appreciate any help. Thanks.
