stylesheets with RGB

[tommy]

Hi,

Normally this is how I use to set the background color of my pushbutton:


colorButton->setStyleSheet("background:red;");

But how do you do it using RGB colors?
This doesn't work:


colorButton->setStyleSheet("background:QColor(200,100,150);");

you do it like this


colorButton->setStyleSheet("background:rgb(200,100,150);");

But why doesn't it work with variables, like below?



int rand1 = 100 + qrand()%155;
int rand2 = 100 + qrand()%155;
int rand3 = 100 + qrand()%155;
colorButton->setStyleSheet("background:rgb(rand1,rand2,rand3);");

Because "background:rgb(rand1,rand2,rand3);" is a string.. and u have "rand1" as a string, not as a number.
Use

QString("background:rgb(%1,%2,%3);").arg(rand1).arg(rand2).arg(rand3)

background: #RRGGBB
also works, where RR, GG, and BB are colour values in hex. ie #FFFFFF being white.
