Clicking Whitespace in a table

[shooogun]

Hi All,

I've been trying to work out how to deselect all cells in a table, by selecting white space in the table.

My table has a set height and width, and is initially empty, so theres a lot of white space. When I add a row and select it, I can't deselect it by clicking the whitespace below. Thats what I'm trying to solve.

I'm using a QTableWidget as my table. Is there anyway to do that?

Reimplement mousePressEvent() and clear selection if itemAt() returns 0 for event->pos(). Don't forget to call the base class implementation to keep it aware of mouse press events.

Awesome, thanks for the help jpn!

I did what you said, and its nearly working . I added

def mousePressEvent(self, event):
      if not self.table.itemAt(event.pos()):
            self.table.clearSelection()

def mousePressEvent(self, event):
      if not self.table.itemAt(event.pos()):
            self.table.clearSelection()

To copy to clipboard, switch view to plain text mode 

It works when I click anywhere on the interface, but not on the whitespace of the table, or other widgets. Has that got something to do with calling the base class? I don't understand the last comment you made. Do I have to make the table aware of mouse events?

Looks like you reimplemented mousePressEvent() of the widget which contains the table. Instead, you should have reimplemented mousePressEvent() of the table itself.

Hey again,

I had to move on to other fixes, so I put this on hold for a while. I understand what you mean jpn, but how do I re-implement the mouse press event of the table. Has that got something to do with the signature?

Subclass QTableWidget and reimplement it for the table. Just like you subclassed QWidget and reimplemented it for the window so far.
