StyleSheet set is slow

Abin

HI,

I tried to set the style sheet. It gets effected, but takes a second to update in UI.
I am trying to change border on mouse press. I need to keep my widget pressed for a second for the change to appear

@void PosButton::mouseReleaseEvent(QMouseEvent *event)
{
qDebug() << Q_FUNC_INFO << "Invoked";

if(rect().contains(event->pos()))
{
    qDebug() << Q_FUNC_INFO << "Emit click";
    emit clicked(this->objectName());
}

m_pBaseWidget->setStyleSheet("QFrame#baseWidget {"
                      "border: 1px solid black;"
                      "border-top-width: 0;"
                      "border-left-width: 0;"
                      "border-style: outset;}"
              );

qDebug() << Q_FUNC_INFO << "Exits";
return;

}

void PosButton::mousePressEvent(QMouseEvent *event)
{
qDebug() << Q_FUNC_INFO << "Invoked";
Q_UNUSED(event);

m_pBaseWidget->setStyleSheet("QFrame#baseWidget {"
                      "border: 2px solid orange;"
                      "border-top-width: 0;"
                      "border-left-width: 0;"
                      "border-style: outset;}"
              );

qDebug() << Q_FUNC_INFO << "Exits";
return;

PosButton is derived from QWidget. I am trying to set style for the QFrame baseWidget inside it.

Also I tried setting property and change but I'm not sure if the style sheet statement I use is in right way

@PosButton[pressed="true"] QFrame#baseWidget
{
border: 2px solid orange;
border-top-width: 0;
border-left-width: 0;
border-style: outset;
}

PosButton[pressed="false"] QFrame#baseWidget
{
border: 1px solid black;
border-top-width: 0;
border-left-width: 0;
border-style: outset;
}

Hi,

Might be a silly question but, why don't you style a QPushButton ?

SGaist,

I use this class as multiple types of buttons.. It has 4 labels of which one has image set on it. In total it is a customized button. So I am forced to use a custom widget instead of QPushButton.

Thanks,

I resolved this issue by setting a timer on the mouse release. The timeout will reset the style of the button

@void PosButton::mouseReleaseEvent(QMouseEvent *event)
{
qDebug() << Q_FUNC_INFO << "Invoked";

if(rect().contains(event->pos()))
{
    qDebug() << Q_FUNC_INFO << "Emit click";
    emit clicked(this->objectName());
}

QTimer::singleShot(150, this, SLOT(styleTimeout()));

qDebug() << Q_FUNC_INFO << "Exits";
return;

}

void PosButton::mousePressEvent(QMouseEvent *event)
{
qDebug() << Q_FUNC_INFO << "Invoked";
Q_UNUSED(event);

m_pBaseWidget->setStyleSheet("QFrame#baseWidget {"
                      "border: 2px solid orange;"
                      "border-top-width: 0;"
                      "border-left-width: 0;"
                      "border-style: outset;}"
              );

qDebug() << Q_FUNC_INFO << "Exits";
return;

}

void PosButton::styleTimeout()
{
qDebug() << Q_FUNC_INFO << "Invoked";

if (NULL != m_pBaseWidget)
{
    qDebug() << Q_FUNC_INFO << "set style";
    m_pBaseWidget->setStyleSheet("QFrame#baseWidget {"
                          "border: 1px solid black;"
                          "border-top-width: 0;"
                          "border-left-width: 0;"
                          "border-style: outset;}"
                  );
}

qDebug() << Q_FUNC_INFO << "Exits";
return;
