[SOLVED] QStyleOptionViewItem draw text ?

Sam

[quote author="raven-worx" date="1371554769"]ok, but why do you want to draw a line edit instead of using a real qlinedit widget?
pro: works our of the box like a qlineedit should
con: may cause performance
[/quote]

I can't use setInexWidget() performance drops heavily !!!

bq. Or why do you want to use a QLineEdit widget at all?

The lineEdit is initialized in the createEditor(). what else you recommend ?

raven-worx

just draw the text with a simple background is enough for you?

How do you exactly change the background color of the line edit when the QValidator fails? By Stylesheet?

Sam

yes the background color for the lineEdit changes through styleSheets.
Yes easiest way is to change the background color of the cell.

Thanks :)

PS : I was thinking too complex :)

raven-worx

thats why i asked ;)

Sam

One more question I would like to ask , is there anyway we can get the background-color of the lineEdit which is set through stylesheets like in the above image the yellow color is set through stylesheet.

Anything like
lineEdit->palette().color(QPalette::?????);

andre

No. It might not even be a color. It might be a brush. Or an image, or...

raven-worx

try QPalette::Background

Sam

and if we are setting the background-color through stylesheets then also its not possible to retrieve the value ?

PS : QPalette::Background return gray color

AFAIK: indeed not. The style sheets are not exposed through the public API other then setting them on a widget or the application.

I'd love to be proven wrong on this one though!

Sam

Thanks Andre,

I think then I have to check/set the color for the painter based on properties specified for the lineEdit.
