don't work qlineargradient for text in QLabel

[GreenScape]

i tried everything. in QtDesigner, gradient for QLabel works perfectly, but when i setting style sheet like this :
"* {color: qlineargradient(spreadad, x1:0 y1:0, x2:1 y2:0, stop:0 rgba(0, 0, 0, 255), stop:1 rgba(255, 255, 255, 255));"

dynamically in my code, i have a white text on my label
what am i do wrong?

here, how i do this:

mpExampleLabel = new QLabel(tr("Cell text example"), this);
mpExampleLabel->setFrameStyle(QFrame::Box);
mpExampleLabel->setAlignment(Qt::AlignHCenter|Qt::AlignVCenter);
mpExampleLabel->setStyleSheet("* {color: qlineargradient(spread:pad, x1:0 y1:0, x2:1 y2:0, stop:0 rgba(0, 0, 0, 255), stop:1 rgba(255, 255, 255, 255));");

mpExampleLabel = new QLabel(tr("Cell text example"), this);
mpExampleLabel->setFrameStyle(QFrame::Box);
mpExampleLabel->setAlignment(Qt::AlignHCenter|Qt::AlignVCenter);
mpExampleLabel->setStyleSheet("* {color: qlineargradient(spread:pad, x1:0 y1:0, x2:1 y2:0, stop:0 rgba(0, 0, 0, 255), stop:1 rgba(255, 255, 255, 255));");

To copy to clipboard, switch view to plain text mode

Looks like you are missing a closing brace in your setStyleSheet statement.

You can also try to skip the "* {".

no, this is just example, i copied style from QtDesigner and loose brace pasting into browser

as i said, i tried everything, without selector (i. e. without "* {" and "}"), with "QLabel" and "*".

here, compilable example:

#include <QApplication>
#include <QLabel>

int main(int argc, char *argv[])
{
QApplication app(argc,argv);
QLabel mpExampleLabel("Cell text example");
mpExampleLabel.setFrameStyle(QFrame::Box);
mpExampleLabel.setAlignment(Qt::AlignHCenter|Qt::A lignVCenter);
mpExampleLabel.setStyleSheet("* {color: qlineargradient(spreadad, x1:0 y1:0, x2:1 y2:0, stop:0 rgba(0, 0, 0, 255), stop:1 rgba(255, 255, 255, 255));}");
mpExampleLabel.show();
return app.exec();
}

i always have a label with white text! (i. e. text color will be always the color of last stop of any gradient). what am i do wrong?

i exeperimented with styles and found interesting stuff:

when i replace

color: qlineargradient(spreadad, x1:0 y1:0, x2:1 y2:0, stop:0 rgba(0, 0, 0, 255), stop:1 rgba(255, 255, 255, 255));

color: qlineargradient(spreadad, x1:0 y1:0, x2:1 y2:0, stop:0 rgba(0, 0, 0, 255), stop:1 rgba(255, 255, 255, 255));

To copy to clipboard, switch view to plain text mode 

with

color: qlineargradient(spreadad, x1:0 y1:0, x2:[B]100[/B] y2:0, stop:0 rgba(0, 0, 0, 255), stop:1 rgba(255, 255, 255, 255));

color: qlineargradient(spreadad, x1:0 y1:0, x2:[B]100[/B] y2:0, stop:0 rgba(0, 0, 0, 255), stop:1 rgba(255, 255, 255, 255));

label's text filled with gradient starts from (0,0) to (100,0), this seems to be bug? values after x1,x2,y1,y2 means proportion of widget but not concrete width/height! x2:1 always means x2=width()*1 but not just one pixel (x==1) same gradient for background-color works perfectly(i. e. x2=width()*1).

No it is not a bug. You can specify if your given coordinates should be treated absolut or streched to the actual painting area. I'd suggest also to skip the first option. Then by default it is streched to the painting area.

what first option? spreadad? how can i specify?

and why absolutely the same style sheet string for background-color works relatively, but for color - absolutely?

HOW can i specify, man!?
