setting text to disabled widget action enables the widget

[user4592357]

i have a disabled widget action
the widget is a tool button
when i set text to button's action, the button and action become enabled
why is this?

class WidgetAction : public QWidgetAction
{
public:
	explicit WidgetAction(QObject* parent = nullptr);
	QToolButton *getButton() const;
protected:
	QWidget* createWidget(QWidget* parent) override;
};

WidgetAction::WidgetAction(QObject* parent /* = nullptr */)
	: QWidgetAction(parent)
{
}

QToolButton *WidgetAction::getButton() const
{
	auto lstWidgets = createdWidgets();
	return !lstWidgets.isEmpty() ? static_cast<QToolButton *>(lstWidgets.at(0)) : nullptr;
}

QWidget* WidgetAction::createWidget(QWidget* parent)
{
	auto pAction = new QAction(parent);
	connect(pAction, &QAction::triggered, [=]() { ... });

	auto pButton = new QToolButton(parent);
	pButton->setDefaultAction(pAction);
	pButton->setAutoRaise(true);
	pButton->setEnabled(someCondition);
	return pButton;
}

// USAGE

m_pWidget = new WidgetAction(this);
insertAction(pFirstAction, m_pWidget);
m_pWidget->setEnabled(false);

later, when i set the text (actually i need to set the tooltip only, but the issue still remains for tooltip too):

auto pButton = m_pWidget->getButton();
if (auto pAction = pButton ? pButton->defaultAction() : nullptr)
{
    pAction->setText(...);
}

after this the disabled button becomes enabled.
p.s. the widget action is added to toolbar.

Hi,

From the looks of it, each time you call getButton, you in fact create a new button.
