I have written a GUI that gets data sent to it in real time and this data is
displayed in a table. Every time data is sent in it is displayed in the table
in a new row. My problem is that I would like to have the data just replace the
old in the first row.
The table has 6 columns (A, B, C, D, E, F) I want the new data to continue
replacing the old data in the same row unless the data that goes under column A
changes, at which point a new row would be added.
Does anyone have tips on how to approach this? I can post a portion of my code
to get a better idea of what I have done.
So that is where I am stuck. I don't how to compare them and I am trying to
avoiding saving the data to a file.
This is the code that I have:
if msg.arg2() != ERROR:
entry = (A, B, C, D, E, F)
self.data.append(entry)
data = self.data
# Display how many runs occurred
self.statusBar().showMessage('Data read. %s Run(s) Occurred.' %
self.runCount)
# Populates table by adding only new entries to the end of the table
lastRow = self.table.rowCount()
self.table.setRowCount(len(data))
for entryPos in range(lastRow, len(data)):
for fieldPos in range(6):
item = QtGui.QTableWidgetItem(str(data[entryPos][fieldPos]))
self.table.setItem(entryPos, fieldPos, item)
self.table.resizeColumnsToContents()
self.table.horizontalHeader().setStretchLastSection(True)
self.currentRunLabel.setText('Current Run: ' + str(self.runCount))
self.currentLineLabel.setText('Number of lines: ' +
str(len(self.data)))
print('End of %s. run: %s. entries found' % (self.runCount,
len(self.data)))
As sayed by Chris "Kwpolska", you can compare the new data with the data
of the first row.
Something like that:
# Get the content of row 0, column A
first = str(self.table.item(0, 0).text())
for entryPos in range(lastRow, len(data)):
if str(data[entryPos][0]) == first:
self.update_first_row(data[entryPos])
else:
self.add_new_row(data[entryPos])
