How to unclick a QPushButton

summit

i am able to click a push button but not able to unclick it.This line button->setDown(false); does not unclick the button,

bool eventFilter(QObject* obj, QEvent* event)
{
	if (obj->isWidgetType())
	{
		// Check if the event is a KeyPress or KeyRelease
		if (event->type() == QEvent::KeyPress)
		{
			QKeyEvent* keyEvent = static_cast<QKeyEvent*>(event);
			// Check if Ctrl is pressed (Ctrl key is Qt::ControlModifier)
			if (keyEvent->modifiers() == Qt::ControlModifier)
			{
				
				// Check if the QColorDialog is currently open
				QColorDialog* colorDialog = qobject_cast<QColorDialog*>(obj);
				if (colorDialog)
				{
					// Find the "Pick Screen Color" button and click it programmatically
					QList<QPushButton*> buttons = colorDialog->findChildren<QPushButton*>();
					for (QPushButton* button : buttons)
					{
						if (button->text().contains("Pick Screen Color", Qt::CaseInsensitive))
						{
							button->click();
							break;
						}
					}
				}
			}
		}
		else if (event->type() == QEvent::KeyRelease)
		{
			QKeyEvent* keyEvent = static_cast<QKeyEvent*>(event);
			// Check if Ctrl is released (Ctrl key is Qt::ControlModifier)
			if (keyEvent->key() == Qt::Key_Control)
			{
				// Check if the QColorDialog is currently open
				QColorDialog* colorDialog = qobject_cast<QColorDialog*>(obj);
				if (colorDialog)
				{
					// Find the "Pick Screen Color" button and uncheck it programmatically
					QList<QPushButton*> buttons = colorDialog->findChildren<QPushButton*>();
					for (QPushButton* button : buttons)
					{
						if (button->text().contains("Pick Screen Color", Qt::CaseInsensitive))
						{
							// Uncheck the button if it is checked (simulate unclicking)
							
							button->setDown(false);
							break;
						}
					}
				}
			}
		}
	}
}

This button requires a esc event to be called to be unselected.

QKeyEvent escapeEvent(QEvent::KeyPress, Qt::Key_Escape, Qt::NoModifier);
QCoreApplication::sendEvent(button, &escapeEvent);

What are you trying to achieve? Click a button? See https://doc.qt.io/qt-6/qabstractbutton.html#click

@Christian-Ehrlicher i want to unclick the pick screen color button after it has been clicked , currently i am not able to do it with code.

I need to manually click once with the mouse to unclick it.

Christian Ehrlicher

Why do you want to do this? I would guess it's a button with checkable property so you have to reset this. Simply look in the source code to see if I'm correct.

@Christian-Ehrlicher This is not a checkable button.

QKeyEvent escapeEvent(QEvent::KeyPress, Qt::Key_Escape, Qt::NoModifier);
QCoreApplication::sendEvent(button, &escapeEvent);

The dialog literally says "Press ESC to cancel" :)
