So I have this (Code Snippet):
Any way I can fix this?
Full code:
#------------------------------------------
# Database Dropdown
#------------------------------------------
#Choose a database to access
Databases = [MainDatabase, CategoryDatabase, UserDatabase]
self.DataBaseComboBox.addItems(Databases)
CurrentDatabase = self.DataBaseComboBox
CurrentDatabase.currentTextChanged.connect(self.DisplayDatabase)
def DisplayDatabase(self):
SelectedDatabase = self.DataBaseComboBox.currentText()
if SelectedDatabase == CategoryDatabase:
TableName = "Categories"
elif SelectedDatabase == UserDatabase:
TableName = "Users"
else:
TableName = ""
#------------------------------------------
# Category Database Display
#------------------------------------------
#Connect to Database
self.db = QSqlDatabase.addDatabase('QSQLITE')
self.db.setDatabaseName(SelectedDatabase)
self.model = QSqlTableModel()
self.delrow = -1
#Initialize Model
self.model.setTable(TableName)
self.model.setEditStrategy(QSqlTableModel.OnFieldChange)
self.model.select()
self.sbar = self.statusBar()
self.CategoryTableView = QTableView()
self.CategoryTableView.setStyleSheet("background-color: rgb(255, 255, 255);")
self.CategoryTableView.setModel(self.model)
self.CategoryTableView.clicked.connect(self.findrow)
self.CategoryTableView.selectionModel().selectionChanged.connect(self.getCellText)
#-------------------------------------------------|
#For Testing: |
self.formLayout.addWidget(self.CategoryTableView)#|
self.setCentralWidget(self.centralwidget) #|
#-------------------------------------------------|
#Original:
# self.formLayout.setWidget(14,0, self.CategoryTableView)
#Only selects cells
self.CategoryTableView.setSelectionBehavior(0)
# 0 Selecting single items.
# 1 Selecting only rows.
# 2 Selecting only columns.
#----------------------------------
#Make Specific Columns Un-Editable/ReadOnly
#----------------------------------
class ReadOnlyDelegate(QStyledItemDelegate):
def createEditor(self, parent, option, index):
print('This column is Read-Only')
return
delegate = ReadOnlyDelegate(self)
self.CategoryTableView.setItemDelegateForColumn(0, delegate) #ID
self.CategoryTableView.setItemDelegateForColumn(3, delegate) #Privilege (for users.db)
#----------------------------------
def findrow(self, i):
self.delrow = i.row()
def getCellText(self):
if self.CategoryTableView.selectedIndexes():
model = self.CategoryTableView.model()
row = self.selectedRow()
column = 1
def selectedRow(self):
if self.CategoryTableView.selectionModel().hasSelection():
row = self.CategoryTableView.selectionModel().selectedIndexes()[0].row()
return int(row)
def selectedColumn(self):
column = self.CategoryTableView.selectionModel().selectedIndexes()[0].column()
return int(column)
#------------------------------------------And it techinaclly works, but when I want to switch between tables, It opens a new one instead of getting rid of the old table and replacing it with the one I want to view (I have attached a screenshot below, showing the problem). Any way I can fix this?
