Change the size of the Tab Widget icon

Raphawel

It is possible to change the icon size of a Tab Widget.

I don't think you need the code to answer me. But if ever I will give it to you.

Thanks for your help

A QTabWidget has a QTabBar where those tabs/text are placed. That is what you need to affect. Example using stylesheet:

// tabWidget is a pointer to a QTabWidget
tabWidget->setStyleSheet("QTabBar::tab { height: 100px; width: 100px; }");
// each tab should now be 100x100px

Though you ask about "icon size", but show no icons.... There is also QTabWidget::setIconSize(const QSize &size).

QTabBar::tab { height: 100px; width: 100px; }");

The order you tell me to make does not change anything. So I don't know if I'm writing it down correctly.
In my case if I want to change the size of the "Control" icon, it is declared as "control_tab" in my QWidget.

So according to what I wrote I put:

ui->control_tab->setStyleSheet("QTabBar::control_tab { height: 100px; widht: 100px; }");

Why don't you start by clarifying why you are asking about an icon size, given that you don't show any icons, while there is a QTabWidget::setIconSize() method. And you quote the line which sets the tab size, no reference to icon. We are not mind-readers, so don't know what you actually want to affect.

the size of the "Control" icon, it is declared as "control_tab" in my QWidget

What "Control" icon??

QTabBar::control_tab { .... This is simply wrong. You can only write ::tab there.

Look at the pictures, I want the Control icon that I circled in red to take up less space. I have already tried to change the iconsize, in the settings but nothing changes

When I run the .exe the Control tab that I circled in red again takes up space. I want to reduce this size just for aesthetics, that's all.

I can't do more simple to explain my problem, sorry.

So I need QTabWidget::setIconSize but why when I change the size of the Control tab in the settings nothing changes?

I see no icon, neither on the Control tab nor elsewhere. What is circled in red is not an icon.
I leave someone else to try to understand what you are asking.

@Raphawel I rectify not icon but tab, so change the size of the tab

Ok it works well, I didn't understand that tabWidget was applied to all the tabs of the GUI.
Thanks for help
