How to insert QProgressIndicator into QLineEdit?

RazrFalcon

I'm trying to insert "QProgressIndicator":http://qt-apps.org/content/show.php/QProgressIndicator?content=115762 into QLineEdit, but for now I only find right padding, but not a height (for all OS).

@LineEdit::LineEdit(QWidget *parent) :
QLineEdit(parent)
{
progressIndicator = new ProgressIndicator(this);

QStyleOptionFrameV2 panel;
initStyleOption(&panel);
QRect rect = style()->subElementRect(QStyle::SE_LineEditContents, &panel, this);
qDebug()<<rect;

progressIndicator->setFixedSize(rect.height(),rect.height());
progressIndicator->move(rect.x(), rect.y());
setStyleSheet(QString("padding-left: %1px;").arg(progressIndicator->width()));

}

void LineEdit::initStyleOption(QStyleOptionFrameV2 *option) const
{
option->initFrom(this);
option->rect = contentsRect();
option->lineWidth = style()->pixelMetric(QStyle::PM_DefaultFrameWidth, option, this);
option->midLineWidth = 0;
option->state |= QStyle::State_Sunken;
if (this->isReadOnly())
option->state |= QStyle::State_ReadOnly;
#ifdef QT_KEYPAD_NAVIGATION
if (hasEditFocus())
option->state |= QStyle::State_HasEditFocus;
#endif
option->features = QStyleOptionFrameV2::None;

Would it help if you moved your code from the constructor to the resizeEvent? That's where I usually do this kind of tricks. There you can be sure you get the correct size information from the widget.

Thanks! It helps.

But now,
@setStyleSheet(QString("padding-left: %1px;").arg(progressIndicator->width()));@
move progressIndicator to left too.
Can I set padding only for text?

Could you show the code you now have, please?
You should of course still position the indicator manually inside the resizeEvent implementation.

@void LineEdit::resizeEvent(QResizeEvent *)
{
QStyleOptionFrameV2 panel;
initStyleOption(&panel); // the save as in the first post
QRect rect = style()->subElementRect(QStyle::SE_LineEditContents, &panel, this);
progressIndicator->setFixedSize(rect.height(), rect.height());
progressIndicator->move(rect.x(), rect.y());
setStyleSheet(QString("padding-left: %1px;").arg(progressIndicator->width()));
}@
