SOLVED: Set Tab Icon with code

Qatto

Hello Developers,

I have been trying to set an icon for a tab in a tabWidget using code but failed so far. Its easier with the form designer but I need to use code to make my app dynamic.
Here's the code for mainwindow.cpp, the rest of the files are the default for a MainWindow project.
Please show me how to set icons with size 20x20p for both tab1 and tab2 below.

mainwindow.cpp
@#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

QTabWidget *tabWidget = new QTabWidget;
QWidget *tab1 = new QWidget;
QWidget *tab2 = new QWidget;

setCentralWidget(tabWidget);

tabWidget->insertTab(0, tab1, "Tab 1");
tabWidget->insertTab(1, tab2, "Tab 2");

}

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

Thanks in advance

Hi Qkato.
Did you try insert tabs with this option?

@int QTabWidget::insertTab(int index, QWidget * page, const QIcon & icon, const QString & label)@

Hope it's util.

Read the manual please:

@
int QTabWidget::insertTab(int index, QWidget * page, const QIcon & icon, const QString & label)

or even QTabWidget::setTabIcon() ...

Qatto

Yes, I can see the parameters but cant seem to get it right.
Please illustrate how I can add an icon that's a resource with path "image/icon.png"

raven-worx

@QIcon(“:/image/icon.png”)@

Qatto

Tried the example, still can't get the icon on the tab. Is it about having the size of the image defined too, and if so how is it done?

Please show you full code and resource file

Thanks for all your posts, When mcosta talked of resource file I took a look at it and there was a prefix for images. Its why the icon wasn't visible all along. Now all is fine.

Thanks so much for the help.
