How to Display/Paint raw image data.

[vinaykusta]

Hi,

I’m new to Qt.

I’m using a QTabWidget. I want to display/paint raw image data in the tab area.

Please guide me how can this be achieved. What factors/resources/widgets are to be considered to achieve this.

Thanks for all suggestion and support.

Hi,

QTabWidget::setTabIcon() : As per my understanding is it used to set an icon for the tab. But, I'm trying to display/paint an entire 800X600 image in the tab area below.

Please let me know how can it be achieved.

Oh, ok. Use QLabel then. Possibly inside QScrollArea.

Thank you.

I'm using Qt creator.

I have used Qt designer to create create MainWindow only.

The following files are generated: main.cpp, mainwindow.cpp, mainwindow.h and mainwindow.ui. The class MainWindow inherits the class Ui_mainwindow generated from mainwindow.ui. Ui_mainwindow class is defined in the file ui_mainwindow.h which does not appear in the file explorer. I understand the ui_mainwindow.h is generated automatically from mainwindow.ui

Further in the mainwindow.cpp, ui->setupUi(this) instantiate the screen. Please let me know what has to be done if I want to create QLabel and add this to UI through cpp file.

Where should that peice of code be written. ?? Please dont mind answering my silly questions. Thanks a lot.

You can put the label directly in Designer. If you don't want to, there is a section in the docs describing how to blend Designer generated forms with your C++ code.
