[Harini]

Hello everyone :)

I'm using Qt 4.7. I want a main window of size 272x380 with a line edit widget in it of completely black color(total window and lineedit). But here i'm unable to change the color of line edit border :confused:
Here is my code and screen shot attached....As displayed in the screenshot I need that red shaded border also black. I tried different types of code but i din't get it.Can any one please help me regarding this issue?? :confused: :confused:


#include <QtGui/QApplication>
#include "mainwindow.h"
#include <QLineEdit>


int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QLineEdit *LineEdit = new QLineEdit;
LineEdit->setStyleSheet("border: black");
//LineEdit->setStyleSheet("border: 1px solid black");


//LineEdit->setStyleSheet("QLineEdit{background: black;}");
// ("QLineEdit { background-color : rgb(45, 45, 45); }");
//LineEdit>setStyleSheet("QLineEdit{background: black;}");


QMainWindow window;
window.setWindowFlags(Qt::WindowTitleHint | Qt::FramelessWindowHint);
window.setWindowTitle(" ");
window.setFixedSize(272,480);

MainWindow w;
w.show();
return a.exec();
}

#include "mainwindow.h"
#include "ui_mainwindow.h"


MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent, Qt::FramelessWindowHint),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
this->setStyleSheet("background-color:rgb(13, 13, 13);");
// this->setStyleSheet("QLineEdit{foregroundRole-color : rgb(244, 244, 244); }");

//this->setStyleSheet("QLineEdit{border: black;}");


}

MainWindow::~MainWindow()
{
delete ui;
}

void MainWindow::changeEvent(QEvent *e)
{
QMainWindow::changeEvent(e);
switch (e->type()) {
case QEvent::LanguageChange:
ui->retranslateUi(this);
break;
default:
break;
}
}


#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow {
Q_OBJECT
public:
MainWindow(QWidget *parent = 0);
~MainWindow();

protected:
void changeEvent(QEvent *e);

private:
Ui::MainWindow *ui;
};

#endif // MAINWINDOW_H

You seem to make the window frameless, but did you try that with the LineEdit? QLineEdit::setFrame(false); Set a styleSheet on the LineEdit as well, similar to how you set it for the window

did you check the attributes of lineEdit manually? look for its properties in your form inside your project.

@ saman_artorious

I got it :) thank you :)

[saman_artorious]

sorry can u please explain me in detail...

inside your form, where you design your UI, on the right side. click on the lineEdit and check its properties on the right side, should you find what you are after there.
