[SOLVED] QStyleOptionViewItem draw text ?
-
Ok i'll explain in detail,
The background color(yellow/red) of the lineEdit changes based on the validator and the current text. The tableview cell should render the same palette/effect of the lineEdit.
The lineEdit is initialized/editable when a particular cell is clicked. I need to set the same effect for a particular cell. For the tableView each cell contains an object of a class that stores the property like text/palette etc.
Eg I need to render something like

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

bq. Or why do you want to use a QLineEdit widget at all?
The lineEdit is initialized in the createEditor(). what else you recommend ?

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?

thats why i asked ;)

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::?????); -

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!
