How to detect whether mouseEvents take place over this or not?

deleted385

When I press the mouse over this (ActionButton), it turns red and as I move mouse (while it's pressed) away from this, the leaveEvent doesn't fire. That's ok, I want to suppress the emit triggered() in the mouseReleaseEvent if it's released elsewhere (not over this). Here's what happened:

First, the Print button is disabled so it shouldn't change color, I wanted to make it light gray when it's disabled and reset the color on isEnabledChanged, looks like there's no such event to handle the effect of setEnabled, is there any?

Second, when I moved mouse away, while it was pressed, from the plus icon on Objects section it was red and as soon as I released mouse emit triggered was called so the file dialog opened. I want it to open the file dialog if the mouse is released over that icon otherwise ignore. Here's what I've for now:

ActionButton::ActionButton(const QString &fileName, const QString toolTip, int size, QWidget *parent)
    : QSvgWidget(parent)
{
    QFile f(fileName);
    f.open(QIODevice::ReadOnly | QIODevice::Text);
    m_document.setContent(f.readAll());
    setToolTip(toolTip);
    m_isChecked = false;
    if(size == 0) setMaximumSize(QSize(16,16));
    else setMaximumSize(QSize(size, size));
    changeColor(QColor(Qt::black));
}
bool ActionButton::isChecked(){ return m_isChecked; }
void ActionButton::setIsChecked(bool value){
    if(m_isChecked == value) return;
    m_isChecked = value;
    if(value) changeColor(Qt::blue);
    else changeColor(Qt::black);;
}
void ActionButton::enterEvent(QEnterEvent*){ if(!m_isChecked) changeColor(Qt::blue); }
void ActionButton::leaveEvent(QEvent*){ if(!m_isChecked) changeColor(Qt::black); }
void ActionButton::mousePressEvent(QMouseEvent*){ if(!m_isChecked) changeColor(Qt::red); }
void ActionButton::mouseReleaseEvent(QMouseEvent*){ if(!m_isChecked) emit triggered(); }
void ActionButton::changeColor(const QColor &color){
    m_document.elementsByTagName("path").at(0).toElement().setAttribute("fill", color.name());
    renderer()->load(m_document.toByteArray());
}

Then I would recommend taking a look at the various button class implementation directly and start with QAbstractButton.

Hi,

Beside your SVG color customization, doesn't QPushButton provide the behaviour you want ?

@SGaist, that's an entry point for understanding QWidget behavior, way of implementing custom functionalities, etc.

As @SGaist said, QPushButton or QAbstractButton already implements that behaviour.

I want it to open the file dialog if the mouse is released over that icon otherwise ignore

if(! hitButton(event->pos())) return;

I wanted to make it light gray when it's disabled

isEnabled() exists in QAbstractButton
and isDown() for highlight the button when clicked inside.

@SGaist, excellent. Needed that changeEvent to change color on enabled/disabled and for hit test rect().contains(releaseEvent->pos()) looks like working perfectly.
