How to highlight a whole line in PyQt5?

Question

PyQt

I am writing a music player . I
display a playlist in QTableWidget. Selecting rows with selectRow().
The code that fires on startup to highlight the first row:

self.window.playlist_table.clearSelection()

self.window.playlist_table.setSelectionMode(QAbstractItemView.MultiSelection)

self.window.playlist_table.selectRow(0)

self.window.playlist_table.setSelectionMode(QAbstractItemView.NoSelection)

And here is the code triggered by the cellClicked() event. (click on a cell in the table):

self.window.playlist_table.clearSelection()

self.window.playlist_table.setSelectionMode(QAbstractItemView.MultiSelection)

row_num = self.window.playlist_table.currentRow()
self.window.playlist_table.selectRow(row_num)

self.media_playlist.setCurrentIndex(row_num)
self.playSong()

self.window.playlist_table.setSelectionMode(QAbstractItemView.NoSelection)

And what exactly is the problem. When you start the window, the first line is highlighted in gray, and after clicking - blue. Moreover, if you click on an empty area without cells with a gray selection, the selection will turn blue. It feels like the widget is in a "collapsed" state. How to keep the table always in the "activated" state, or how to select rows correctly?

Answer 1

It 's because of this line
self.window.playlist_table.setSelectionMode(QAbstractItemView.NoSelection)
that "NoSelection" is grayed out.
