Dynamically changing QLabel background-color
Hi everyone!! I m newbee on the QT platform. :) now I have actually a problem on QLabel. Problem is that QLabel background-color is not changed as dynamically on the my gui which is designed. Firstly I have added 3 slider(for RGB in range(0-255)) to gui and then QLabel. in side of programming I use together with QPalette on the QT 5.3 release Result in I wanted a user to change QLabel background-color dynamically. Althought I research this problem I could not find a convenient way to solve it. I hope you can help to me :) as you 're senior Coder. I have also added below sourcefile and" Code "snippet":http://uploaded.net/file/g6axidqj.
//also I use uchar array for RGB Values so that I m going to able to change the color of QLabel according to position of slider(as a mutual exclusion ) in the Next time.
@MainWindow::MainWindow(QWidget *parent) :
palet = ui->Color_label->palette();
void MainWindow::on_Green_slider_2_valueChanged(int value)
This might give some hints:

Hi Breeder! very thanks for your reply. now I found a solution while I research in net. it seems that I should had added below code line while QPalette is created.
this link says " that ":http://qt-project.org/forums/viewthread/4291
@title->setAutoFillBackground(true); // IMPORTANT!
QPalette pal = title->palette();
