Odd behavior with a selected QTableWidgetItem

[Endless77]

The QTableWidgetItem doesn't support the setstylesheet method, so it doesn't seem that I can use stylesheets to alter its appearance.

Im not sure i understand

Is QTableWidget::item not for the items ?

You must set the style sheet on the TableWidget, NOT item.

Please see here

Oh, update:
This is the one u are after
QTableWidget::item:selected{ background-color: red }

Sorry, the other one will color ALL items. This is only on selected.

If I understand correctly, then setting the stylesheet for the table would mean that all of the QTableWidgetItems in the table would have that style. The background color for any given row may be different than another row.

Hi
QTableWidget::item
is for all items.

QTableWidget::item:selected{ background-color: red }
Is only for the selected ones

so that should work for you ?

Hi,to add to @mrjj, also I think your original ->setBackgroundColor() should work fine, but with a slight tweak:

jobEntry[index].jobId->setBackgroundColor(QColor(255,0,0));

(At least it works for me:-)

@Endless77 said in Odd behavior with a selected QTableWidgetItem:

. The background color for any given row may be different than another row.

Oh sorry i missed that. Just though you tried to match selection color for one color so to speak.
Then stylesheet is not optimal as you would have to change for each row.

Okay, so I thought the QTableWidget::item:selected would be promising, but it didn't work for me. The table looked the same as usual without anything selected, but when I selected a row, the normal selection coloring was in place.

I was also hopeful about the second suggestion, using setBackgroundColor(QColor()). That had no effect in my code. I changed the code in my slot that changes the colors, but the selection color was the same when the row was selected. When I deselected the row, that's when I saw the red background.

I can't seem to be able to override the default selection behavior for the QTableWidgetItems even when I specifically set the color to be different.

@Endless77
Hmm its hard to guess at.

How did u color all the rows in differnt colors in first place?

[Endless77]

I used the same method, setBackgroundColor, to set the color in each QTableWidgetItem when the table is first displayed. I figured that using it again when something was selected would simply change the background color.

@Endless77
well yes it should, if you use tableSelectionChanged
and set it there. Didn't try but it sounds ok.
