示例1:
QStackedWidgetEventFilter *QStackedWidgetEventFilter::eventFilterOf(const QStackedWidget *stackedWidget)
{
// Look for 1st order children only..otherwise, we might get filters of nested widgets
const QObjectList children = stackedWidget->children();
const QObjectList::const_iterator cend = children.constEnd();
for (QObjectList::const_iterator it = children.constBegin(); it != cend; ++it) {
QObject *o = *it;
if (!o->isWidgetType())
if (QStackedWidgetEventFilter *ef = qobject_cast<QStackedWidgetEventFilter *>(o))
return ef;
}
return 0;
}示例2:
QToolBoxHelper *QToolBoxHelper::helperOf(const QToolBox *toolbox)
{
// Look for 1st order children only..otherwise, we might get filters of nested widgets
const QObjectList children = toolbox->children();
const QObjectList::const_iterator cend = children.constEnd();
for (QObjectList::const_iterator it = children.constBegin(); it != cend; ++it) {
QObject *o = *it;
if (!o->isWidgetType())
if (QToolBoxHelper *h = qobject_cast<QToolBoxHelper *>(o))
return h;
}
return 0;
}示例3: managedButtonGroups
ButtonGroupList ButtonGroupCommand::managedButtonGroups(const QDesignerFormWindowInterface *formWindow)
{
const QDesignerMetaDataBaseInterface *mdb = formWindow->core()->metaDataBase();
ButtonGroupList bl;
// Check 1st order children for managed button groups
const QObjectList children = formWindow->mainContainer()->children();
const QObjectList::const_iterator cend = children.constEnd();
for (QObjectList::const_iterator it = children.constBegin(); it != cend; ++it) {
if (!(*it)->isWidgetType())
if (QButtonGroup *bg = qobject_cast<QButtonGroup *>(*it))
if (mdb->item(bg))
bl.push_back(bg);
}
return bl;
